Inseminating Cathy (mff Sister In Law)

Shortly after the kitchen door closed, I heard Cathy’s car start and leave our driveway.

I found Ann, my wife of ten years, alone in the kitchen.

“What was that all about?” I asked.

It was the second time in three weeks that her twenty-two year-old sister had stopped by for an unannounced afternoon visit--very unusual.

“Oh, Cathy is just having some problems with Ted,” replied Ann, getting up to start making dinner.

I had some difficulty imagining that. Ted and Cathy seemed perfectly suited for one another, almost to a fault. Cathy had latched on to her mother’s religious conservatism which Ann, thankfully, had rejected. Ted, her husband, is also a religious zealot--a devoted follower of some right-wing evangelical minister on the east side with a church complex the size of a small college campus. Given their mutual commitment, body and soul, to their religious beliefs, I guess I just assumed that they wouldn’t be casualties to any form of marital strife, at least none for which there was not a spiritual answer.

“Anything we can help with?” I asked, expecting the answer to be no.

“Not at the moment, anyway,” came her reply.

Though I was damned curious as to what the “problems” could be, I wasn’t about to press Ann to disclose matters she was clearly reluctant to discuss.

“Can you round up the boys and get them cleaned up for dinner?” she asked.

I did as she requested.

****

I didn’t give our conversation that day another though until two months later. I came home to again find Cathy’s car in our driveway. Upon entering the house, I could hear the girls talking in the kitchen. Rather than intrude where I may not be wanted, I decided to head to my den to relax and watch ESPN. Ann joined me there about a half an hour later.

“Has Cathy left?” I asked.

“No, she is still in the kitchen. She’s thinking about staying the night.”

“Really,” I replied. “More troubles at home?”

“In a manner of speaking,” Ann responded as she moved to sit in one of the two chairs across from my desk. “Cathy has asked for our help with her and Ted’s problem. I need you to keep an open mind.”

Despite their differences, Ann had always been very close to Cathy, closer than any siblings I had ever known. Ann had been Cathy’s protector and provider for a number of years as they had both grown up in a rather abusive household. I genuinely think there is nothing that Ann wouldn’t do for Cathy and, so long as it did not violate her religious beliefs, nothing that Cathy would not do for Ann. Now, I had to wonder how Ann’s commitment to Cathy was going to obligate me. I jumped to what I thought was the obvious answer.

“Honey, you know that I think of Cathy as family,” I said. “She is welcome to stay with us as long as she wants.”

“Oh no, it’s nothing like that,” Ann replied. “No, it’s something very, very different.” Ann took a very deep breath and continued, “Cathy and Ted have been having problems conceiving. They have been trying since they were married with no success.”

“What has that to do with us?” I asked. “That sounds like a medical problem to me.”

“And, you’re right. Both Cathy and Ted went in for some testing last month. It turns out that Ted’s sperm count and quality are very low. The doctors give them one chance in fifty of conceiving naturally.”

“Ok, so isn’t that what artificial insemination is intended to solve? I still don’t see how this is our issue.”

“You’re right again,” continued Ann. “Except, Ted absolutely refuses to participate in the procedure. His minister says that artificial insemination is a sin and contrary to God’s plan. According to the minister, if God intends Ted and Cathy to have children, He will provide them no matter what the odds.”

“And, Cathy does not share this view?” I asked.

“She is troubled by the moral implications of the procedure, but she is more troubled by the thought of not having children.” Ann paused for a moment. “Oh Scott, Cathy has always wanted children, almost more than life itself. She doesn’t think that she can stay in the marriage knowing that it was medically possible to have children but for Ted’s refusal to participate in the procedure.”

“Honey, I still don’t see how any of this involves us. She isn’t asking us to give her one of our kids, is she?”

“No, but you are a bit warmer. She would like you to donate sperm so that she can be inseminated behind Ted’s back. Then, when she gets pregnant, she can claim that it was God’s will or a miracle or something and Ted will be none the wiser.”

The suggestion stunned me for a moment. I sat back in my chair and took a deep breath.

“Why me?”

“Two reasons, really,” replied Ann. “She cannot buy sperm from a donor bank and keep it a secret from Ted. He would see the expense and ask questions. Also, donor banks have limited information concerning the physical attributes of their donors. It is possible that her child would look nothing like either her or Ted causing questions. You, on the other hand, look quite a bit like Ted, and our children look like they could be their children. She figures that if your sperm combines with my eggs to make kids that look like they could be hers, your sperm will combine with her egg to generate similar results.”

I was genuinely speechless at Ann’s proposal. She clearly wanted me to donate sperm to be used to impregnate her sister. In those few moments, all I could think about is how weird it would be to see Cathy’s kids knowing that they were my kids, too. This would not be a situation where I would never see or know my progeny. They would be there, at every family gathering, at every holiday dinner, from now until the end of time. I expressed these concerns to Ann to be sure that she had considered them.

“You think I haven’t?” came her immediate reply. “I have thought of little else since Cathy first suggested the idea a couple month ago. So, I will certainly understand if you are unwilling to do this. But, it would mean so much to Cathy, and so much to me, if you would agree.”

I looked hard at my wife, taking in her auburn hair and fiery green eyes. I could tell that she was conflicted. But, I could also tell that she was passionate in her desire to help Cathy obtain what was clearly key to Cathy’s happiness. Ann wanted me to say yes; she needed me to agree to help her sister. Casting my gaze down her five foot, ten inch frame, over her C-cup breasts, along her ample, full hips and long legs, I knew that I could not refuse her request. I would do this, not for Cathy, but for Ann.

“What do I need to do?”

****

Later that evening, I found myself alone in our bedroom with a plastic cup and thoughts of what I had gotten myself into. Ann had explained that Cathy would stay over so that she could take the fresh semen down to her clinic first thing in the morning for the insemination procedure. I was expected to supply the sample. I had thought they would want it first thing in the morning, but Ann assured me that it would be better if I provided the sample before going to bed-- something about men producing more ejaculate in the evening than in the morning.

Ann offered to help me, but I just couldn’t fathom her jacking me off to extract cum which was to be placed into her younger sister’s womb. Just too weird.

So, it came to pass that I was laying on our bed trying to find a mental image sufficiently erotic to induce an orgasm.

Several minutes passed without success. I just couldn’t shake the feeling of how weird and unnatural this entire enterprise was. It was then that I realized that I had to simply change my point of view. Ann wanted me to, in fact had begged me to, do this for her and for Cathy. There was something definitely erotic in that fact. So, if they didn’t think it was weird, I shouldn’t either.

Then I turned my mind to Cathy. Since her marriage to Ted, and her associated indoctrination by his church into its religion, it had been difficult for me to see Cathy in a sexual light. Yet, here she was doing something distinctly sinful in the eyes of her husband and her church. Could I not find something erotic in the idea that this devotedly religious married woman was not just willing, but eager, to accept into her womb the sperm of a man other than her husband.

I felt my cock twitch.

Bingo! It was erotic. A wife begging her husband to impregnate her sister. A young, religiously pure woman asking a man other than her husband to allow his sperm to be introduced into her womb. Freeing my mind, I focused on the delightfully naughty aspects of what had been asked of me. It was as though my wife had asked me to be unfaithful with her sister. It was as though her sister had asked me to take the place of her husband in their marital bed.

My cock gradually grew to full erection.

Infidelity, now there was an erotic thought! Ann and I had been married for going on ten years and had monogamously dated for three years prior to that. I’d only ever been with one other woman besides Ann, a girl really, who I dated for a time in high school. We’d fooled around on a couple of occasions. But, other than that, Ann had been my only lover and the only lover that I had really wanted. I loved the smell of her auburn hair and the way her hips responded to my light caress.

But, now that I was considering infidelity in a different light. Consensual infidelity--the thought of sharing myself physically, not emotionally, with another woman. The thought of experiencing the touch, smelling the hair, enjoying the reactions, of a totally different sexual partner. And, having that sexual partner be my wife’s sister.

My cock was now hard and streaming pre-cum.

I found the thought of my wife’s sister willingly, eagerly accepting my sperm deep within her vaginal walls to be a powerful motivator, maybe more powerful than the thought that my wife had begged, almost pleaded with me to allow her sister to take that sperm within her vaginal walls.

I began to consider Cathy as a pure sex object, a receptacle for my sperm and nothing more. How would her body react to my presence? What would her hair and lips smell and taste like? Would she squirm at the initial tickle of my tongue across her clit? I began to consider how cloistered her sexual experiences may have been. Was she a virgin when she married Ted? Had she ever experienced oral sex, giving or receiving? Had she ever experienced an orgasm?

My mind elected to paint her as a complete sexual novice, inexperienced in all but the most basic sexual practices.

I could feel the telltale signs of orgasm rising deep within my balls.

Cathy was so physically different than my Ann. Where Ann’s breast were large and fully developed, Cathy’s were barely two mounds sitting atop her chest. Where Ann’s hips and ass were full and curved, Cathy’s were relatively straight and flat. In some ways, Cathy presented an almost boyish frame when compared to the complete woman that is my Ann. And, Cathy’s short blond hair stood in stark contrast to Ann shoulder-length, deep-auburn hair.

I wonder if her pubic hair is just as blond, I thought to myself.

My balls and shaft twitched in anticipation of ejaculation.

Cathy’s lips, her vagina, they must be just as different from Ann’s as is the rest of her body, I thought. I imagined that Cathy’s vagina presented nothing more than a barely visible slit lightly covered with wispy blond hair. Cathy was probably uncomfortable with her sex, uncomfortable exposing herself to a man. I imagined how her sex might smell, sweet and inviting. I imagined how tight she must be, what it would be like to penetrate her lips with my cock...

I fumbled quickly to grab the plastic cup I had been given as I felt my body let loose the torrent of semen that had been rising within my testicles. Sitting up while continuing to stroke myself, I placed the cup below and in front my head as the first pulse of cum existed its eye.

My hands clamped down on the base of my shaft as my body shuddered from the power of the contractions now forcing the jism from my body. In my mind, I imagined my cock impaled deep within my sister-in-law’s vagina, depositing directly into her those juices which I knew tomorrow would actually be placed within her by a very different, more impersonal means.

“Ugh,” I grunted, as my hips struggled to push my penis deeper within my hand. Again and again, flood after flood of milky white cream passed from my head and into the cup. To my surprise, when I was finished, the cup was nearly filled with my spunk. Sweat dripped from my brow as the last, tiny contractions took hold at the base of my manhood. With the last contraction, I ran a loop made with my fingers the length of my shaft to extract the very last drop of sperm I had to give.

There, I thought, Ann would have to be pleased with my effort. I certainly had delivered more than I had expected to under the circumstances.

****

It was just after midnight when I awoke to discover Ann absent from our bed. I always found it hard to sleep without her body next to mine, but given the evening’s events and the exhaustion that had followed, I was somewhat surprised that my sleep was disturbed this night.

Then I heard the noises--voices coming from the guest bedroom. I could tell in an instant that Ann and Cathy were engaged in a conversation.

“Oh, Ann, I will forever owe you for this.”

“Don’t be silly, we just need to be sure that Ted never, ever finds out. Never a word, promise.”

“Promise. Are you kidding, this would end my marriage. Do you have the...um...stuff.”

“You mean Scott’s sperm? Really, sis, you can be so strange sometimes. How can you be committed to doing this and still have so many hang ups surrounding sex. At least you need to start calling things by their proper names.”

“It’s just, I mean, you know, it makes me uncomfortable. I don’t know what the big deal is about sex anyway. If it wasn’t necessary for children, I am sure I’d never do it again, ever.”

“How can you say that? Doesn’t it give you any pleasure?”

“Pastor John says that sex is the devil’s playground, and that any pleasure derived from it is evil.”

“And, you believe that?”

“I don’t know sis. I know that sex has brought me nothing but pain and sorrow. I know that Ted’s problems with sex have led me to these drastic measures in an effort to provide me what I want from life. I know that I feel terrible guilt and remorse when I think about sex. It is hard for me to see anything good that comes from sex in my life.”

A period of silence followed.

“I guess I see your point,” replied Ann, “but you should know that sex can be the most joyous and wonderful expression of love that two parties can share. You should also know that sex has the capacity to bring to you pleasures that have no equal in everyday life. Well, here is Scott’s sperm. Did you bring the syringe?”

Syringe, why do they need a syringe?

“Yeah, here it is,” replied Cathy. “Wow, Scott really had a lot of...sperm...in him. Ted was only able to fill the cup a quarter full when he had his...sperm...tested. Now, all my friend says we need to do is use this to inject the...sperm...into my...you know.”

“Vagina?”

“Yes, vagina. It works just like a man would delivering the...sperm.”

Oh my God, I thought to myself, they are trying to artificially inseminate Cathy by themselves. It will never work. Don’t they know that? I guess not.

“Ok, I have it in the syringe,” I could hear Ann say. “Are you ready? Spread your legs. There, guide it in as deep as you can take it.”

My cock became instantly erect. In my mind’s eye, I could see my thirty year-old wife sticking a tube up her twenty-two year-old sister’s twat filled with my sperm with the intent to deposit that sperm in her womb. I began absent mindedly stroking my shaft, the top of my head completely covered in pre-cum.

“There, it’s in,” replied Cathy.

“Done,” stated Ann. “Now hold your legs up over your head for fifteen to twenty minutes. That’s what my OB/GYN told me to do after sex with Scott when we were trying to conceive.”

“Well, hopefully, I won’t have to inconvenience the two of you again like this.”

“Hey, sis, don’t get your hopes up too high, this is unlikely to work first time out of the box.”

For the second time that night, I released a torrent of sexual energy and pleasure in the form of a shooting fountain of gooey white cream. This time, instead of catching it in a cup, I captured it into a tissue, which I quickly discarded.

Then, I rolled over an went to back to sleep.

****

As the days passed, I became increasingly bothered by what Ann and Cathy had attempted. As I learned more and more about artificial insemination, it seemed to me less and less likely that their home brewed approach would work. Moreover, what I read suggested to me that Cathy was running a serious, continuing health risk.

As I expected, I learned that the first attempt had been unsuccessful and that Cathy expected to be visiting again in a couple weeks for another try.

Three days prior to Cathy’s planned visit, I confronted Ann with what I knew.

“Look, Ann, I understand what you and Cathy are after. But, if she is going to do this, she needs to do it correctly. That means, she needs to engage the help of trained professionals with the right tools.”

Ann was deeply embarrassed that she had lied to me about their plans.

“I know, I know,” Ann replied. “I told Cathy it was crazy to try it this way. But, she insisted. She says that she can’t go to a clinic because the clinic won’t do it without Ted consent, which of course she can’t get. Plus, she doesn’t have the money to pay for it anyway even if she went to another clinic claiming to be a single woman. So, as low as the odds may be, she sees this as her only viable choice.”

“But, it isn’t really a choice, is it? It is a waste of time, and a potential risk to her health. It is not an acceptable substitute either for the preferred medical way or for nature’s own way with Ted. She is better off accepting the sperm that Ted’s dick is capable of delivering naturally into her vagina than she is working to get mine in there this way.”

Silence followed. I could see that Ann was seriously considering what I had said.

“You are right,” she said, finally, “this is a sad substitute for nature’s way. I need to talk to Cathy about this Friday night. But, just in case she wants to try again, I need you to preserve your sperm--agreed--no beating off.”

“Promise.”

****

I came home from work on Friday to again see Cathy’s car in the driveway. I assumed that Ann had been unsuccessful in talking Cathy out of another futile attempt. Oh well, I thought to myself.

Cathy barely spoke to me throughout dinner. Indeed, she could barely bring herself to look at me. The resulting tension I was made to feel was making me crazy.

As Ann whisked the kids off to bed, I decided that I needed to clear the air.

“Cathy, you haven’t said one word to me all night. We can’t continue this if it’s going to affect our relationship. We are going to have to interact with one another as brother-in-law and sister-in-law in all sorts of family situations.”

“You must think terrible things of me...” she started.

“Not at all. I think what you are doing is noble and selfless, else I wouldn’t have agreed to help. I just think that you have to see the bigger picture for a moment. What you are doing is placing your own health at risk. It was one thing when I understood that you were planning to use the services of trained professionals, but it is an entirely different thing now that I know you are trying to do this in some bastardized, home-chemistry-style experiment. I am just worried about your health. Your odds this way are no better than your odds with Ted.”

Cathy quietly began sobbing.

“I understand that rationally,” she managed between her sobs, “but, emotionally, and maternally, I simply don’t want to accept any of it.”

At which point, she looked deeply into my eyes. Until that moment, I had never really seen the depth of the blue captured in Cathy’s eyes. I could understand Ann’s passionate desire to help her sister. In that moment, I wanted nothing more than to wrap her kid sister up in my arms and make all of her troubles go away.

As Ann returned to the main floor after putting the kids down, I caught her in the hallway to ask her if I should excuse myself to fill the cup again.

“Hold off for now,” she told me. “I haven’t been able to get a clear answer from Cathy as to what she wants to do.”

“Well, from what she just said to me, it seems pretty clear that she’s committed to continuing with the attempts.”

“Give me just a couple minutes to chat with her.”

I retired to the den to await Ann’s word.

Five minutes turned into fifteen, then into thirty. I expected that Ann was trying to get her sister to see the folly of their efforts and was having no success. Never in a million years would I have guessed at what Ann was really discussing with Cathy.

Forty-five minutes later, I finally heard footsteps heading up the stairs. I assumed that it was either Ann checking on the kids or Cathy retiring for the night--or possibly both. Then, I heard footsteps coming back down the stairs. A couple of moments later, Ann stuck her head through the den’s door.

“The kids are both fast asleep,” she started.

“Good,” I interrupted, “so, what’s the verdict?”

“She’s definitely committed to trying again. She has no faith that she will ever conceive with Ted. So, in her mind, the odds with him are more like one in a million.”

“Ok, well then, I will head upstairs to give you girls what you need.”

“Not so fast,” Ann said, holding her hand up to stop me.

I sat back down in the chair behind my desk.

“Cathy and I are wondering if you’d be willing to...help...us more directly with the insemination process?”

“I’m not sure what more I have to bring to the table than is already available to you,” I replied.

“Well,” Ann paused, “you have a...tool...which we don’t possess and which may significantly increase our chances of success.”

Ann looked directly into my eyes. It took me a moment to unravel the complete implications of her statement. Ann held my gaze.

“You mean....you want me to....you have to be kidding....aren’t you?” I stammered out.

“I am totally serious. So is Cathy. I don’t think you understand how committed Cathy is to having a child. She is convinced that she won’t have a child with Ted. So, in her mind, she either leaves Ted or has a child with someone else. But, she loves Ted and can’t bear to think of leaving him. So, to her, the question is whether she has the child with a complete stranger who she picks up somewhere or with you. Under that reasoning, you would be doing her the greatest service possible.”

“That’s all well and good for her mind,” I replied. “But, what about your mind, huh? You understand what you are asking? You are asking me to fuck your sister and keep fucking her until she has my child.”

“I know what I am asking, and I know it is a lot. But, the thought of my baby sister bedding stranger after stranger, undertaking all of the health and physical risks that such an approach would entail is really too much for me to bear. I love her. In my mind, you’d be--we’d be--giving her the greatest gift possible under the circumstances.

“What if I really enjoy fucking your sister, huh, what then?”

Ann stood up from her chair and took my hand causing me to rise from my chair.

“Well, I would certainly hope that you will enjoy fucking Cathy,” she said, looking straight into my eyes. Placing my hand against her breast, she continued, “after all, your pleasure is sort of a necessary prerequisite to what we are trying to accomplish here.”

****

Ann told me to wait in our room while Cathy prepared herself to receive me. How does one of Cathy’s religious beliefs prepare themselves for adultery I wondered. What had started as the sublime had absolutely transcended to the surreal. I decided to take a shower and clear up. I really wasn’t sure what the girls had in mind for me. If the recent past was any indication, it wouldn’t be anything like what I expected.

Ann met me at the shower door as I turned off the water and grabbed a towel.

“Good thinking,” she said, referring to the decision to get washed.

Hey, an ‘A’ for effort I thought. That’s got to be worth something.

I had never been a man susceptible to performance issues. And, ordinarily, the thought of screwing Ann’s baby sister--not just with Ann’s permission, but at Ann’s insistence--would have been plenty of reason for me to ‘rise’ to the occasion. However, tonight was proving to be a night of first, and I was worried that it might be a night of firsts in the performance area, too.

I gently toweled the water from my body and applied a couple sprits of cologne.

Meanwhile, Ann reappeared from her closet wearing one of her wispy nighties.

“Why’d you put that on?” I asked.

“Well, I thought I would look pretty silly in there in jeans while the two of you are doing it.”

“In there? You mean that you are going to be in the room with us while I’m doing your sister? Honey, I am not sure that I can perform under that type of pressure.”

“Well, let’s see what happens. Cathy insists. Says that it will seem a lot less like cheating if I am there, too. It will be sort of like I am giving my blessing.”

I looked at her with bewilderment.

“Hey, we’re supposed to be doing this for her. I figure it is the least I can do. Plus,” she said again turning to me, “I want to see the look on your face when you stick that big dick of yours into her tight, little twat.”

Whoa, where did that come from? I looked for a moment into Ann’s eyes. I could tell that she was serious. What had I gotten myself into?

****

I had been told what to expect. The lights would be dimmed; Cathy would be dressed in Ann’s terrycloth robe. The plan, as it was explained to me, was to have Cathy position herself doggie-style over an ottoman which they had placed in the room at the foot of the bed. Cathy would then hike up the robe to allow me to “access” Cathy’s pussy with my cock.

This obviously well scripted and blocked approach to sexual relations did nothing to ease my performance anxiety issues. I really wondered if I would be able to perform, to hit my requisite mark, when called upon to do so by the script.

Ann assured me that she would be there to assist me when and how I needed to get the job done. She assumed that these assurances would ease my fears. They didn’t.

Ann knocked gently at our guest room door.

“Come in,” I heard Cathy say from behind the door.

It’s show time, I thought to myself.

As Ann pushed the door open, I saw Cathy standing before the guest bed. As promised, she wore Ann’s white terrycloth robe dr*ped across her shoulders and cinched tightly about her waist. Notwithstanding the bulky robe, it was impossible not to realize that concealed beneath it was the lithe form of a sexy woman not yet twenty-three years of age. I felt my thirty-three year-old frame respond on an instinctive level to her impending deflowering. How many other men have been where I am about to go, I wondered.

Though it seemed a bit silly at the time, Ann insisted that I wear boxers into the room. Now, I was glad that she had. I would have felt very foolish indeed walking into the room buck naked.

As Ann closed the door behind us, I faced Cathy looking into her face. She tried hard, but she couldn’t hide her trepidation at what was about to transpire.

“Are you sure you want to do this?” I asked.

“Oh, yes,” came her immediate response, almost too rehearsed. “More than you can possibly know.”

An awkward silence descended over the room.

Thankfully, Ann was there to take charge. Following Ann’s instructions, Cathy positioned herself on her hands and knees so that the ottoman supported her chest and stomach. I took my place behind Cathy and removed my boxers. My member was at half mast, at best. I started stroking it in an effort to help build the erection. I felt more fear than zeal towards what was coming.

Ann glanced in my direction, noting my distress.

“Are you ready Cathy?” Ann asked.

“Ready,” came the noticeably shaky response.

With that, Ann grabbed hold of the hem of the robe and lifted it up exposing Cathy’s ass to my sight for the first time. Sitting on the ground next to Cathy and looking up at me, Ann softly asked, “doesn’t Cathy have a nice ass, honey?”

She certainly did. While it was relatively flat, it was tight and athletic. I could feel my member starting to fill with blood.

“Yes,” I replied as if in a trance.

“Oh, I can tell you do,” continued Ann, her voice taking on a low, husky tone. “Cathy, spread you legs a little and roll you hips forward a bit so that Scott can appreciate what he’s about to experience.”

As she did what Ann asked, I could see Cathy’s pussy come slightly into view. Her labia protruded only slightly framing the cleft within which I knew was hidden her vaginal entrance. Laying over her labia were slight whiffs of pubic hair. The smell of sex gently descended over the room.

The sight of my sister-in-law laying prone across a piece of furniture, my wife at her side, exposing her sex to me was undeniably erotic and arousing. My cock was responding to Ann’s calculatedly naughty approach.

“Honey,” Ann continued, “do you recall what I told you in our room about seeing that big cock of yours enter my baby sister?”

I fell to my knees almost involuntarily as those words passed across Ann’s lips. Harden steel now occupied the space between my legs.

Then, Cathy looked over her shoulder at me. “Scott,” she said, “please fill my pussy with your cum.”

With those words, pre-cum started draining down from my head. Any thoughts of performance anxiety were completely washed away. I was mesmerized by the images which had been placed before me--my sister-in-law’s most private areas exposed for me to see, Cathy’s head and face in profile as she looked back to me over her shoulder, my wife’s pleading eyes begging me to insert my hardened cock into her sibling’s tiny little love canal. At that moment, I could imagine no pleasure greater than that which I was about to experience as my manhood penetrated Cathy’s snatch allowing my shaft to come into the most intimate contact possible with her inner vaginal walls.

“Husband, rub the tip of your head against my baby sister’s tight little slit,” suggested my wife.

Who was I to refuse. On my knees, I moved myself so as to place my penis in position to penetrate my sister-in-law’s snatch. Taking my shaft in my hand, I gently brought my head into momentary contact with Cathy’s slit. The feeling was immediately electric for both of us. I felt a shiver of raw passion pass across my body as I fought my instinctual desire to thrust myself forward and complete the copulation. Cathy also reacted immediately to the touch, pulling slightly away as though to tease me by denying me the penetration that my body desperately wanted. Then, as quickly as she moved away, she gently pushed her hips back against my manhood to complete her instinctual tease by seemingly inviting further exploration of her inner regions.

Ann’s eyes were locked on the intimate contact taking place between her husband and her sister. I noticed that her hand was gently rubbing her own pussy as she watched the primal dance before her.

Almost involuntarily, my hips responded to the pressure applied by Cathy’s movement back against my shaft. Gently, but earnestly, I shifted my hips forward. My head pressed eagerly against Cathy’s vaginal sphincter muscles attempting to push through them to the expected nirvana that lay beyond.

Cathy let out a low moan.

“Am I hurting you?” I asked.

“Nooo,” came her deep, guttural response, “you feel so good to me back there. Keep going. Please, keep going.”

Gently, I grabbed Cathy's hips through the terrycloth which still encompassed them. In response, Cathy push herself back against me harder. I pulled myself towards her using her hips as a guide.

Suddenly, I felt my tip push pass what had been the guardians of Cathy's virtue. Her walls immediately grabbed it, issuing a warm and pleasurable welcome that I don’t think I will ever forget.

I grunted slightly at the incredible pleasure of the moment while Cathy let escape a second, very slight moan.

In immediate response to the penetration of my tip, Cathy jammed her torso hard back against my groin, taking the rest of my head and shaft deep within her snatch in one continuous motion.

Our infidelity complete, Cathy let out a sharp exclamation of combined emotional pain and physical pleasure.

We rested together for a moment. For myself, I was overcome with the attack on my senses as I took in the experience of the tightest vagina I had ever known. The complete length of my shaft felt as though it was encased in a form fitting glove specifically designed to maximize my enjoyment. Of particular note was the tightness encircling the very base of my cock. It was as though Cathy’s vaginal sphincter muscles were fighting desperately to close themselves up again in order to repulse the invader that had passed through only to be frustrated in that effort by my now stone-like shaft blocking the way.

As for Cathy, I could only imagine the thoughts that might be swirling in her head. Certainly, she had to be dealing in some measure with the shame and remorse associated with the adultery to which she had now become a party. But, I hoped that whatever her negative feelings, she was embracing the purpose for which she was sacrificing so much. Further, I prayed that she would allow herself to enjoy the joining of our bodies towards the end to which she was now inescapably committed.

Momentarily forgotten, Ann reasserted herself into the moment. “Oh Scott, you sticking your dick into my sister is the most erotic scene I have ever witnessed.” Turning to her, I saw that Ann had propped herself against the wall with legs spread wide vigorously working her clit with her fingers.

Gently, indeed tenderly, I initiated a slight rocking motion against Cathy’s ass. Cathy responded to my rocking by attempting to match my slight rhythm. The resulting gentle movement of my head deep within Cathy’s womb was more pleasurable than any sensation I had heretofore ever known. If Cathy was a drug, I could easily see myself becoming an addict.

“Oh,” Cathy exclaimed after a couple minutes, “Scott, your cock feels so good.”

“Gawd, Cathy, you are so fucking tight. I can’t believe how tight your little twat is.”

“Is that a good thing?” asked Cathy.

“Oh, Cathy, that’s a great thing to men,” Ann interjected.

“Well, then start fucking that tight, little twat,” urged Cathy, giggling slightly.

I needed no more encouragement. Gently I moved my hands from Cathy’s hips up to the sides of her waist. While doing so, I began to extend my rocking motions back and forth so as to withdraw my head further down her canal before driving it home again. Back and forth our bodies moved as Cathy worked to match my actions, thrusting herself back as I pushed myself forward. Soon the room was filled with the unmistakable slopping, slapping sounds of deep, penetrative fucking and the gentle grunts and moans that the participants often make.

I don’t really know how long we continued apace. Paradoxically, it seemed as though we maintained our mutual rhythm for what seemed to be both moments and days. Ann had cautioned me to cum as quickly as I could. Going in, I was definitely motivated to do so. But, the pleasures derived from the combined assault on my senses, the touches, the sights, the smells, the sounds, rendered time meaningless to me.

Apparently overcome by her own senses, Ann had once again moved over next to me.

Taking my face in her hands, she said, “Honey, I fucking love you so much.” With that, she brought her mouth close to mine and kissed me hard and open on my lips. Her tongue attacked mine in much the same way that I imagined my cock was attacking her sister’s pussy. I was then experiencing the twin sensations of my wife’s kiss and her sister’s twat.

Removing her face from mine, Ann looked me in the eye. “Deliver your load into her for me,” she said returning to her low, husky tone.

“Yes,” joined in Cathy, again looking at me over her shoulder, “Please, fill my womb full of your cum.”

Seeing Cathy looking at me in profile again, I was enthralled by the sight of her hair against her ears and side of her neck. Moving my hands from her sides to her shoulders, I leaned forward to place my chin at the base of her neck. Deeply, I inhaled that combined smells of her flaxen blond hair and the sweat that had formed in the nap of her neck while continuing to jam at her womanhood with my member.

With that, I felt the telltale tingling that signals for me the onset of orgasm rise for the first time in the base of my balls.

“Cathy,” I managed to grown as I quickened my pace against her hips and ass, “tell me again, what it is that you want.”

Looking again over her shoulder, rocking hard in response to my thrusts, Cathy forced her eyes to lock with mine. Bare inches away from one another, Cathy responded. “Give me a baby. Fill my womb with your sperm and make me pregnant.”

That was all I needed. I could feel my release now moments away. I decided to share that information with the others in the room. “Here I come Cathy. Get ready to feel me fill your womb.”

Just as the spasms marking my ejaculation started to build, Ann’s fingers gently started rubbing the space between my balls and asshole. With increasing pressure, she massaging my prostrate as my ejaculation spasms cut loose.

“That’s it,” Ann exclaimed, while applying pressure to my pleasure button, “fill my little sister, give her a baby.”

Millions of years of primal instinct took control of my body in an instant. As if in an epileptic fit, my hips began convulsing uncontrollably, attempting to drive my penis deeper into what had been the source of so much pleasure. Deep within Cathy’s body exploded a flood of milky, white fluid from my man-head. As each spurt of jism was force from my body, a blast of euphoric pleasure traveled up the length of my spine. A scream of raw emotion and passion escaped from my throat.

“Uuughhh!” I groaned.

Beneath me, I felt a subtle change to Cathy’s response to my physical presence. As the first floods of man juice were splashing against the back of her vaginal walls, the walls of her vagina started to contact and convulse in their own rhythm around my shaft. I vaguely became aware that Cathy was, herself, in the opening throws of her own orgasmic response to what we had done. Slowly she began to writhe against my body as her spasms joined with mine in an effort to extract the maximum amount of spunk my body could deliver.

“Oh my God, that feels soooo good!” she exclaimed, arching her back and pushing hard against my chest.

Deep within her, Cathy’s spasms took control of her vaginal walls using them to work my member like a dairy farmer bent upon extracting every last ounce of milk from her prized cow. Wave after wave of muscular contraction caused her walls to grip the base of my shaft and squeeze along its length up to its head. With each wave of contractions, my cock spewed forth an additional spurt of the creamy, white fluid needed to fertilize Cathy’s egg. With each round, millions of sperm were added to the growing pool deposited at the base of Cathy’s cervix. And, as Cathy’s orgasmic contractions continued, her cervix repeatedly dipped into that pool, inviting more and more sperm to make their way into her uterus and beyond to complete the task for which they had been deposited.

An exhausted silence fell over the room.

Slowly, the cloud of euphoric tremors which had gripped my mind and body subsided. As my convulsions subsided, so did Cathy’s. Ann ceased her prostrate massage and let her hand trace up and rest in the small of my back. For a few moments, I allowed myself to rest against Cathy’s back, my now rapidly deflating shaft still buried deep within her slit. Gently, as my rod lost the last of its erection, Cathy’s now stretched and abused vaginal sphincters finally won their battle to eject the intruder. As my penis slid from Cathy’s now engorged lips, I felt a small glob of cum slide out along with it.

With my cock now fully disengaged from her body. I rocked myself back allowing my butt to rest upon my heals. Cathy remained prone across the ottoman, her sexually depleted body dr*ped over it both drenched and exhausted. In that position, I could not help but stare at Cathy’s now swollen and gaping vulva. My God, I thought, I’ve done it--I fucked my married, religiously conservative, sister-in-law. I marveled at how beautiful her vulva appear to me in that moment, distended and stretched, gently leaking my man seed from its entrance.

Ann seemed to be the first to regain her senses.

“Cathy,” she said, softly, “you should roll over on to you back and raise your hips.”

As she gave these instructions, Ann took the hem of Cathy’s robe and covered her ass and pussy shielding it from my further gaze. With her modesty restored, Cathy gently slid off the ottoman, rolled over onto her back on the floor, and raised her hips and legs under the coverage provided by the robe. She appeared tired, but strangely satisfied. I felt an almost uncontrollable urge to move next to her and take her into my arms. But, I resisted the urge knowing that such intimate contact would be unwelcome and misinterpreted both by Cathy and by Ann. The thought almost made me laugh. I could fuck Cathy, but I couldn’t cuddle her.

So I kept my distance but ended the silence.

“Are you alright, Cathy?” I asked.

“I think so,” she said. “I have never felt anything quite like...what I felt while you were... cumming.”

“You mean you have never experienced an orgasm?” asked Ann, almost in disbelief.

“Is that what it was?” responded Cathy in complete innocence.

“Well, that’s what it looked like to me,” replied Ann.

“That’s what it was,” I confirmed, “and a big one if I am any judge.”

After a moment’s thought, Cathy said, “well, hopefully that’s not the only first that will come from this night.”

****

Though Cathy’s sexual evening was over, I sensed that Ann’s was just beginning. She was clearly still very sexually charged when we made our way back to our room. I was convinced that I had never cum harder, never delivered more sperm, than I did inside Cathy’s pussy. I really wasn’t certain that a second performance was even possible. But, Ann would not be denied.

“Scott, the two of you were so, so hot together. Watching the two of you, being with you in the room, is the most erotic thing I have ever experienced.”

Notwithstanding her statements, I remained concerned over when the other shoe would drop.

“Are you sure that you are still OK with it Ann. I mean, it’s not every woman who is happy seeing her husband unload himself into another woman, let alone her sister.”

“Honey, I see absolutely nothing wrong with what we did this evening. Plus, I am convinced it was right for Cathy, too.”

I started to make my way to the bathroom to wash up.

“Hey, where are you going?” she asked.

“I thought I’d wash up before coming to bed.”

“Oh no you don’t,” she replied grabbing my arm. “I want you to come to bed with me just the way you are.”

“But honey, I am covered with sweat and sex. Please let me rinse off.” I was particularly aware of Cathy’s sexual juices still coating my cock and running all over and through my pubic hair.

“Not on your life,” came the reply. “I want to experience you just as you are, coated in sexual smells and all.”

Ann would absolutely not be denied. On one level, I was bothered by the thought that Ann might actually be turned on by my body coated in her sister’s sexual juices. However, on another level, I could appreciate her desire to share in the moments that she had just witnessed. I could understand that the sensations that remained attached to my body may be the best available substitute to allow Ann to live vicariously in the moments that I had enjoyed with her sibling.

As I settled into out bed, Ann was immediately all over me. She kissed me hard upon my lips as she pressed her breasts hard against my chest.

“Tell me, did it help...the things that I said?” she asked after a few moments.

“Absolutely,” I replied. I would have said if it wasn’t true, though it was.

“Was she...different...than me?”

“Yes,” I said more cautiously.

“Was she...tighter...than me?”

This question required a more carefully worded response. Ann knew the truth. She was just teasing me. But, still, it wouldn’t do to be too enthusiastic with the answer.

“You know she was, but not better.”

The answer seemed to satisfy.

“I never realized how noisy fucking can be, the way that you two were slapping your bodies together. And the smells in addition to the sounds. The sex smell was so sweet in the room. Did you notice it?”

“Yes,” I replied.

Her hand came to rest upon my cock, gently tickling the shaft.

“Boy, you are still wet down there, is that you or her or both do you think?”

“I imagine its some combination. Her vagina was pretty well lubricated at the end. I suspect that she hadn’t experience someone of my size before.”

“I don’t think she had either,” Ann replied, eyes wild with excitement. “Pull back the sheets, I want to see it.”

I was a bit embarrassed at the request, but I could hardly refuse. I pulled the sheets slowly back away from my groin.

“Boy, you are covered with juices, aren’t you? I hadn’t realized how messy sex can get,” she said, staring intently at by pubic region and lightly lifting my limp member with her thumb and index finger. Then, unexpectedly, she lowered her nose close to my groin and inhaled deeply.

“Ohhh, I love that sweet, sweet smell. Do you suppose its Cathy that I am smelling all over your dick.”

My cock twitched at the brazenness of her statement.

“I suppose,” I stuttered in replied. “It’s probably more her than it is me.”

Then, Ann did something even more unexpected. She bent further forward and licked the very tip and underside of my dick with her tongue.

“Oh wow, that tastes so sweet, too,” she said, as she returned to her upright position sitting next to me in bed.

Before I could respond, she suddenly leaned forward again engulfing my complete member in her mouth. I felt her tongue swirling about my head and shaft, licking from them the combination of Cathy’s vaginal juices and my spunk off that remained from our illicit encounter. As Ann did so, my member filled again with blood.

“Umm, the combination of you two together tastes so good to me.” She paused looking up into my eyes. “What do you think of your wife being turned on by the taste of your cum mixed with her sister’s juices?” she asked.

I wasn’t certain what had gotten in to Ann. While never a sexual prude, she was never the most sexually adventuresome person either. And, that was really fine with me. But, the person occupying my bed this evening was someone new, someone adventuresome, someone willing to take risks, and someone willing to enjoy the moment. There was absolutely no doubt that the thought of Ann enjoying the combined taste of her sister’s pussy and my spunk was exciting to me. My cock sprang to almost instant attention as she continued to lick the combined juices from around my pubic region.

Deciding to throw caution to the wind in that moment, I suggested, “Ann, what do you think licking my juices directly from your sister’s naughty little pussy would have tasted like?”

Ann couldn’t respond orally as her mouth was full of me. But, I instantly knew her response. She rotated herself about so as to position her pussy over my mouth in a sixty-nine position. Once situated with her knees on each side of my head, she started grinding her labia and clit against my tongue and lips. Meanwhile, she continued attacking my cock with increased zeal while grinding her hips hard into my face. We continued in this position for several minutes until a felt a small spasm pass across Ann’s body.

I knew this tiny little orgasm would not satisfy Ann this evening.

Sure enough, once her body ceased its twitching, she repositioned her knees so that they straddled my hips. Positioning her slit over my rock-hard cock, she took me into her body in a single, downward thrust. As my dick penetrated her inner folds, she arched her back slightly and let out a deep, guttural groan.

Once she settled down with her full weight on my member, she made her request. “Tell me what you were thinking as you fucked her.”

Ann’s full, rounded breasts were hanging before me. Gingerly, I ran my fingers under their curves and across their tops ending on each of the nipples. I ran my thumbs and index fingers over and around each of her nipples, applying slight pressure to each. Then, I began my response.

“Before we started fucking,” emphasizing the word in the dirtiest, nastiest tone possible, “I imagined what it would be like to feel the newness of a different pussy, a young and very tight pussy, caressing my penis with its walls.”

Ann started rocking slowly back and forth on my hips.

“My cock has become somewhat accustom to your feel and grip. I wondered how her feel and grip would be different than yours,” I continued.

“Was it different?” she asked in a quiet and expectant voice.

“Very much so,” I responded truthfully. “Her opening is so much tighter than yours. Her entire vaginal canal is so much tighter. It was hard to penetrate her, she was so tight.”

Ann was rocking hard now back and forth against the base of my penis. As she rocked forward, she let out slight groans.

“Did she...did she...feel good...being so tight?” Ann finally managed to get out between the gasps accompanying her thrusts.

“Very,” I said, in the deepest, most earnestly aroused voice I could muster. “I remember thinking that her pussy was like the hand of a milk maid jacking me to an orgasm.”

Ann was virtually throwing her body down against mine following this statement. Ann’s eyes were on fire with passion. I could tell that she was close to coming again as her pace quickened further against my shaft.

“Was it...nice...to blow...your wad...into...into my...little sister’s...pussy?” Ann asked between the next series of thrusts and grunts.

Unexpectedly, I felt the sudden onset of a second orgasm rising within me, too. Her last words had reminded me of the extreme pleasure I had experienced deeply planting my man-seed inside her sister’s womb.

“Oh God, YES!” I exclaimed, raising up to hug Ann about her waist as she continued her rocking motions. I sucked on each of Ann’s nipples, taking in the sweet smell of the sweat generated by her continued effort against my member. I could feel an orgasm rising within her for a second time as the grip of her vaginal walls tightened ever so slightly on my cock.

“Would you...like to...fuck her...again?” Ann asked just as her orgasm took control of her hips and back.

“Oh, yes, yes, yes,” I responded, “I would love to pump her full of my cum again and again.”

With that statement, my mind and body completed its recreation of the events transpiring only a few short minutes earlier in the evening. In my mind at that moment, my cock was trapped in Cathy, not Ann. In my mind, I was depositing my load deep within Cathy, not Ann. In my mind, it was the spasmodic contractions of Cathy’s vaginal walls in orgasm working overtime to extract every last drop of jism from my body. I had not thought it possible to deliver a second load of any appreciable size after the load I deposited with Cathy. Yet, in response to Ann’s orgasmic massage, my member strained to find and deliver whatever reserves were held in the deepest recesses of my testicular glands. The resulting extraction process from those deepest regions of my very soul was simultaneously exquisitely painful and pleasurable.

“Uuughhh!,” I exclaimed, grabbing Ann’s torso and burying my face between her breasts.

The spasms taking hold of my scrotum and prostrate moved into overdrive in a seemingly desperate attempt to compel the delivery of every last drop of spunk forcibly wrung from my body. As our mutual orgasms subsided, I could feel a slight trickle of my seed escaping from Ann’s opening to run down over my balls and onto the sheets. For moments which seemed to be years, we held our mutual embrace, Ann’s legs now wrapped tightly about my waist. I could hear her heart beating rapidly as my ear pressed hard against her sternum. The trickle that I had felt gradually grew to a small stream. A large wet spot had now formed upon our bed.

Eventually, Ann pulled my head away from her chest so that she could look into my eyes.

“Honey, I want you to know how much I truly appreciate all that you did this evening.”

No remorse, sorrow or guilt, just genuine appreciation and happiness. I could only hope that it would last.
