My new sister in Law!..Adultery

Pages: 1

My brother and I have never been very close. Steve was a gung-ho, go getter type that was always striving for more, bigger and better things in life. My name is Gus and I'm a little more laid-back and enjoy a little slower pace than my big brother. Needless to say, when Steve called me to tell me he was getting married and wanted me to be one of the ushers, it wasn't exactly the highlight of my life.

Now Steve is 4 years older than me, he's 30 and I'm 26. He met this girl at a downtown restaurant where she is a hostess. Her name is Sandy and she's more my age. She came from a lower-middle class family, her father was Irish and her mother Puerto Rican. She was nice to look at, but her intellect was a bit lacking. She looked great in a dress and pair of heel that really showed off her bronze legs. I kind of felt as if she was a bit of a gold-digger since our family was fairly well to do and Steve had certainly propelled himself even further up the financial security ladder. Still, it was easy to see what Steve saw in the dark haired beauty.

I was a bit pissed that Steve hadn't even made me the "best-man". That honor went to his best friend Gary (who also introduced Steve to Sandy). Gary was very full of himself and I couldn't really stand the guy. He always was telling you how great everything was that he ever did , and he could care less about anyone else.

So I went and got fitted for a tuxedo, bought Steve and Sandy a wedding present and dutifully went to the rehearsal at the church followed by the rehearsal dinner at my father's country club. There were at least forty people there including bridesmaids, ushers, family of the bride and groom and a few close friends. After the dinner and several rounds of "Toasts" to the happy couple, I went outside to have a smoke and wandered around the grounds for a while.

I re-entered the building downstairs were the men's locker room was and went in to take a pee. That's when I heard some noises in the far corner of the locker room and went to see who was down there. I quietly approached the last row of lockers and peered around the corner to get the hottest view of the night!

There in the dimly lit back corner was Gary, the best man, his pants down around his ankles and kneeling in front of him was Sandy, with her mouth firmly surrounding his erect cock shaft! I pulled back from the corner of the locker and thought a minute. What were my options? I could step around the corner and yell "surprise" at which point the whole wedding would be over and I wouldn't have to wear that stupid tux and my brother would somehow blame me for his fiancée's infidelity. I really wanted to figure out a way that this would be all blamed on Gary and I would never have to hear his insufferable chatter, or there was a third option.

I slipped my cell phone from my pocket and turned it on "camera mode".

I disabled the flash and peaked around the corner with the viewfinder in front of me. Sure enough, Sandy was noisily slurping on Gary's cock and he was pressing his hand on the top of her head trying to get her to take more of his member down her throat. I clicked a picture then retreated to take a look. The picture was a bit fuzzy, and Sandy's was pretty much unidentifiable covered by her hair falling forward over her face. I leaned around the corner and waited for another shot, and as luck would have it, Sandy pulled her hair away from her face and I got a clear shot of her mouth open wide for the best-man's cock.

I snuck away from the two and headed upstairs to join the party. There was my idiot brother chatting and laughing with some of his buddies, not knowing his slut bride was sucking off the best-man downstairs. A few minutes later, Gary appeared from the outside door to the patio, then shortly after, I saw Sandy coming from the direction of the ladies room (No doubt she had to clean the cum from the corners of her mouth!).

I left the party and headed home, trying to brainstorm the best way to use the damming photo on my cell phone camera. I had to admit Sandy looked pretty damned sexy as she sucked Gary off down in the locker room. I figured if she was slutty enough to give old Gary a blow job at the rehearsal dinner, then she probably was willing to do something nice for me as well.

I downloaded the pictures to my computer and left them on my camera to be able to show my proof to Sandy. Next morning, I got showered and dressed in my tux and headed off to the church. The whole wedding party was there, Steve and Sandy were outside getting some pictures taken by the photographer. I waited for the right time, but it had to be before the ceremony.

After all the wedding party had done the picture bit, I snuck down to the bride's dressing room and asked if the bridesmaids could leave us alone for just a minute while I talked to my future sister-in-law. She smiled at me as the others left the room and I asked her to sit down for a minute. She had no clue what this was all about until I said "I need to show you something." I flipped my cell phone open and opened up the photos and showed her the two shots from the previous night.

Her mouth fell open and all the color left her face as she looked up at me, totally dumbfounded. "What are you going to do with those Gus?"

I started to give her a very self-righteous answer like "When the pastor asks if there is anyone here who knows why these two can't be married......... "

"Oh God No Gus, You Can't!" she squealed and tears started to well up in her eyes.

"My brother should know that his best friend and his wife-to-be were cheating on him the day before the wedding!" I said.

"Gus........PLEASE, Please, there has to be some way we can keep this between you and me." she asked all sincere and sobbing.

"Why should I?" I said "What's in it for me?"

Sandy thought for a moment and replied "I could pay you......."

I cut her off in mid sentence and said "I don't need your money."

"What do I have that you want?" she asked, almost knowing the answer before I spoke.

"Tell you what, I'll keep my silence during the ceremony if you agree to see me after you return from the honeymoon." I said

"I guess I don't have much of a choice now, do I?" She said as she looked at me with those big puppy-dog eyes.

"No, you really don't. So go upstairs and get married, and go off to your South Pacific honeymoon, but when you come back......... You're mine to do with as I please." I said sternly. "Either that, or Steve gets an anonymous email with pictures of you giving Gary a blow job."

Sandy lowered her head and said "Okay" very softly.

As I left the dressing room, I was already getting a woody at the thought of fucking my new sister-in-law.

The ceremony went off as normal, and when the pastor asked the question, all I could do is smile and lower my head. The reception was fine, everybody got plenty of food and drink, and then the bride and groom went and changed into their traveling clothes for their trip to the airport. As they were bidding their goodbyes to everyone, I worked my way over to Sandy and whispered in her ear "You're mine when you get back."

I expected a look of disgust or even a little anger, but I was surprised to see a sly little smile at the corners of her lips. I kissed her on the cheek and they were off for two weeks of sun and fun. I spent many of the next several evening stroking my cock and thinking about what I'd do with my new little prize.

Steve and Sandy returned on schedule and two days later, Steve returned to work. I didn't want to appear too eager, so I waited a couple days and finally gave Sandy a call.

It was about 10:00 in the morning and I dialed their number.

"Hello Sandy, It's Gus." I said without any inflection in my voice.

"I've been waiting for you to call." She said.

"I think I'll come over this morning." I told her.

"Okay." She said.

I thought for a minute on the things I had been fantasizing about and sprung it on her. "And one more thing... I want you to be dressed in your wedding dress."

"What!" she said in protest, "What the hell for?"

"Just Do it!" I said and hung up.

About a half hour later, I pulled up in front of my brother's condo. I had been watering his house plants and stuff, so I already had a key.

I took the elevator up to the eighth floor and down the hall to his unit. I knocked on the door and waited. After 30 or 40 seconds, I heard the deadbolt turn and the door opened. There standing before me, just as I asked, was my new sister-in-law dressed in her wedding gown!

"Come in." she said and pulled the door open a bit more.

I came into the apartment and she closed the door behind me.

The wedding dress was not one of those old-fashioned kind with a neckline up around the woman's throat, no, this was an open neckline, cut fairly low and showing off Sandy's nice "C" sized titties. I took her by the hand and walked in towards the living room. Then I turned and put one hand around her waist and the other behind her head and drew her into a kiss.

She didn't offer any resistance, in fact, she quickly got into the whole idea and was soon thrusting her tongue into my mouth as I pulled her tightly against me. I could feel my cock springing to life as our bodies and mouths massed together. I lowered my other hand down and cupped both hands under her ass cheeks and pulled her mound against my manhood. I heard her groan with excitement as our kiss continued.

Finally, she pulled back and our mouths released.

"That was nice, Really nice!" Sandy said as my hands released their grasp of her nice tight ass cheeks.

I took a couple steps over to the couch and sat down. Sandy came over and stood directly in front of me.

"How about you do to me like you did for Gary?" I asked calmly.

A small smile shaped her lips as she knelt in front of me with her dress billowing all over the floor. I laid back and made sandy do all the work, unbuckle my belt, undo my pants and slide them down far enough to let my cock spring free. I knew that Steve's cock and even Gary's might have been a bit longer than mine, but my cock was by far bigger around which got a little "Mmmmm" from Sandy before she positioned herself over my shaft and began to lick the pulsating helmet-head.

It was quickly obvious why Gary was willing to risk his friendship with my big brother! Sandy had a fantastic technique for stroking and sucking and deep-throating your cock like no woman I ever knew. She was noisy and wet and hungry to take my entire cock into her mouth.

Her hands would squeeze and release and stroke and pull until I was on the verge of cumming in no time.

I quickly slipped my cell phone from my pocket and flipped it open.

Sandy didn't seem to mind getting photographed, In fact she seemed to be posing a bit for the camera. I kept clicking away as Sandy got me closer and closer to cumming. With one hand, I kept clicking pictures while my other hand grabbed a fist full of her hair and pulled her up off my cock just enough to have the stream of thick, white cum splash against her face. Sandy eagerly slurped up any globules of cum as my hips bucked uncontrollably.

Sandy slid back onto her knees and smiled at me. "You've got a powerful weapon there buddy!" she said jokingly.

"Yea, and now I want to try it in a different place!" I said.

I kicked my pants off my feet and took her by the hand into the master bedroom. I sat on the bed facing the mirrored wardrobe closets. I urged her to stand up in front of me. Then I had her pull the shoulders of the dress down on her arms and expose her breasts. Again I was clicking away as she bared her titties.

"Now, slip off your panties and give them to me." I instructed her.

Without hesitation, she raised her wedding gown and exposed her panties.

Then she slipped them down and kicked them into my lap.

"Now turn around and raise up your dress so you can see your pussy wiggle down onto my cock!" I said.

Again, without any hesitation, she did exactly as I ordered. I looked around the side of her and could watch our reflection in the mirror as she poised directly over my cock for a second or two, the started bearing her weight down and forcing my cock to part her labia until my cock was fully inserted inside her married cunt. I quickly wrapped my hands around her and fondled her tits as she began to undulate up and down on my shaft. Her pussy was like a warm Jacuzzi bath swirling around my erect cock. Her nipples were hard as pebbles and she leaned back against me so I could nibble on her neck.

After about twenty minutes like that, she rose up, shed her dress (but still had her garter belt, nylons, bra and heels) and plopped down on her back in the middle of the bed. I quickly got on top of her and slid deep inside her. She quickly wrapped her long legs around my back and locked her heels behind me as we started fucking wildly. She was grunting and groaning and soon was screaming "Cum in me you asshole, fuck my married pussy!"

I could feel her orgasm hit her just a few seconds before I unloaded my second blast of cum deep up inside her cunt. She bucked and quivered and shook for at least two minutes before she finally started to calm down. I'd never fucked a woman with that much energy!

After laying together for the next fifteen minutes or so, I got up and started to put on my clothes. Sandy just laid there smiling and I watched her pussy oozing cum onto the bed. She walked me out to the door and I retrieved my pants and finished dressing.

"I hope this wasn't just a one-time act of blackmail Gus..........

Because I'm going to need more of what you've got!"
