Fuck me Sister,,, I dare you, he whispered

It's surprising how tight you can squeeze a hard cock and the sensations are pleasurable. A soft dick, not so much, not the same sensations, but a good hard squeeze without stroking it, seems quite pleasing to Mark. I ease my grip and suck this prime meaty cock into my mouth. He moans aloud and throbs in my mouth.

Mark is 6', slim fit with dark ragged hair that always looks a mess. He works hard to look that unkempt. He maintains a slight stubble and has deep dark eyes that melt my panties, and finally, I have my brother's perfect cock inside my mouth again. It feels like it belongs there, pulsing, dancing on my tongue.

I cradle his big smooth shaved balls in my right hand. They feel heavy, full of hot gooey sperm and tonight, it's mine. We are twins, and as such, share a bond beyond what non twins, can understand. My other hand grips his lovely cock and I slowly hand job his thick meat while I suck it deep into my mouth and work my tongue around the bottom of the meaty head. I'm giving my brother the wealth of every cock I've sucked. Every cock I've drained has taught me something, and I'm using every ounce of that knowledge on my brothers thick 8.5” cock.

“Fuck me Sis,,,, I dare you to fuck me” he moans. I take my hand off his cock and deep throat his steel hard dick to the base and pause. I stay there, breathing through my nose, tonguing the tender underside. His cock stretches my mouth wide, almost too much, but I have it all in my mouth and lodged in my throat. I stay for a solid minute, fighting off the impulse to gag. He lightly lays his hand on the back of my head and prays “Oh god”. He knows now, I've grown into a cock sucker. No longer that girl that did not know what she was really doing at 16.

I raise my head quickly, clearing my lips from his meat and gasp to get a little more air into my lungs and he moans out, “Fuck Sis,, that's incredible”. I lick a path up his torso and straddle his waist then settle my firm 36c tits against his chest. As I kiss my brothers lips that fat cock pokes at me, nudging at my wet pussy lips, seeking to join it's wet counterpart. The meaty head spreading my pussy lips feels so good. I can feel my pussy tingle, my wetness is flowing and ready. Mark's cock searches my slit, and finds the entrance to it's sisters body, but that's all. He won't go further.

He throbs in the wetness of my outer lips, stretching me wide and the tip of his dick sniffs at my hot tunnel wanting to defy god and enter me. I want filled by my brothers dick. “Do it,,, I so dare you” he whispers into my mouth.

We grew up in a small house and shared a bedroom until we were twelve. The sign on our bedroom door read, “Mark and Mandy”. We've seen each other naked many times, but when we began to blossom into pubescence our parents had managed to save enough to buy a new home and we gained our own separate bedrooms.

I missed sharing the room with him. But as we became more curious about our changing body parts, playing house began to include some kissing, and touching of my little breast and his peter. It was a handful back then, but I did not know what big or little was really. I just remember, I could make it go from soft to hard really fast and thought that was funny. Sometimes I'd pass his door and if no one was looking, I'd show him my perky young tits, rubbing them and twisting my perky little hardened nipples, because I'd learned it would harden his dick.

As the years blew by we began to learn more about sex. One day while wrestling about and fighting over a game controller, I reached under the leg of his shorts and grabbed his dick to force him to give up the controller. He did not, and I held on to his dick as it grew to hardness in my grasp. He relaxed and laid down the controller and I began to stroke his cock. He began telling how good it felt. It was the first time I gave my brother a real hand job. I loved the way his cum blew out of his cock so high in the air and rained down on top of both of us as he jerked came hard. It was both surprising and exciting.

We also had learned brother and sister should not touch each other in “bad ways”. That we'd go to hell and all sorts of things for doing so wrong and even having thoughts about it would an ungodly sin. But, we liked playing with each other, it was comfortable and seemed a lot more right than it did wrong. So natural and right. I loved his cock, even as a child.

That's when “The Dare” became a thing for us. Mostly for Mark. His moral compass pointed a little more north than mine. When he wanted to mess around, certainly, it would not be his fault if I was the one who did it. So, He'd dare me to jerk him off. He wanted it bad, but he needed to feel I was the bad one, I had to do it to him, therefore, he was innocent from incest. Once, when I came home from a date with a local boy. We'd played around with some petting, and I let him finger my young hairy pussy. He made me wet and horny and I gave him a hand job, but I got no release. So at home that night, I sneaked into my siblings room, and snuggled into bed with my brother. I spoke softly as to not awaken out parents“Finger my pussy” I whispered. “No, that's wrong” he whispered back. I took his hand an lay it on my horny wet pussy and pressed on his middle finger the slightest amount and “assisted” it into my pussy. He fingered me good, for as long as my hand was slightly on his, “making” him finger me until I came. He never failed to make me cum. The other guys I don't think really cared or knew enough too make a girl cum.

“Jerk me off Sis,,,, I dare you, ” he then whispered softly. It was a teenager's game, we both used it many times to condone our immoral incestuous actions, that way blame could be put upon the other, or at least in our minds. To dare the other, was really a request in sheep's clothing. He always needed jerked off if he fingered me first. I liked that my body excited my brother.

I was still heated from him fingering me to orgasm. “That's nasty” I teased. “Go ahead, touch it, I dare you to” he whispered underneath the covers. “Okay, I will” I said. I reached into his tighty whities and found my brothers stiff cock. Perhaps it had grown some too. His dick was far larger than my date's had been.

I decided to try something new. I always enjoyed Mark's dick. I stroked his cock slow and could barely see it as I lay underneath the dark covers. I lowered my head down and took my brother's cock into my mouth and wow, I liked the feeling of his dick in my mouth.

My girlfriends had begun to experiment with blowing their adolescent boyfriends, mostly laughing about the icky cum that lay inside. But Mark's cock felt so nice in my mouth, soft, warm but still a very hard thing, and it jumped in my mouth. I was so excited to feel his dick jump inside my mouth. In about thirty seconds his cock throbbed hard then my tongue felt a bulge streak up through the thin skin along the bottom of his cock, then a hot liquid slammed into the back of my mouth, then another, and another. My mouth was filling up with what I've heard called cum. I did not know there was so much of it I thought as my brother moans deep, “Oh Sis” and his body shakes and does crazy funny things.

I've heard a couple of the girls say they swallow their boyfriends gooey spunk. So I swallowed. The huge mouthful of warm thick cum went down, and after a couple more blast painted my tonsils again, I swallowed anther load of my brother tasty cum. I'd heard different things about cum, but I liked my brothers. I kept my mouth on his cock until it went softer. “God Sissy, that was, wow” he said. Mom and dad split up. Mark and I separate and were two states away from each other. We were 16, and far apart, but we talked every day. We could tell if the other was having a bad day, and when one of use were, a call would come over the phone, and it would be me or him and we'd feel better instantly. We had a connection distance could not dull.

We grew up. We are now 28 and neither married. We'd both dated a lot, and had normal lives as things go. Mark got serious with a woman, and he moved her in with him. That lasted about six months. I cared little for her, but he seen something in her I did not. I guess he cared for her, but In the end they had a fight and she moved out. He felt alone and abandoned and wanted me to visit him for a few days get out and have some fun on the town.

I decided to take him up on his offer to stay with him a few days. I thought it would be fun, and help him forget about that looser bimbo. When I arrived, he seemed as glad to see me as I was to see him. We hugged each other hard and spent most the day catching up on things, and later bar hopping.

About 10pm, I decided to fire up a big fat joint and chill for the evening. Mark hit the joint a few times too, and we were feeling great. We laughed about the childhood days and eventually nervously, we began to talk and snicker about the messing around we'd done as kids and earl teens.

I began to feel a tingle between my legs as we talked about the first time we got each other off and our many sexy little interludes involving much touching and kissing. I also noticed my brother's cock had begun to snake down his pajama bottoms and was tenting it nicely. I'd not seen his cock since we were 16 and I swallowed my first load of cum. We did not say any thing about our current state. But clearly, my twin was feeling very similar to what I was, only his was more visible. I told him I was going to get ready for bed and went to the guest room and found my favorite sleeping tee shirt. Thin but not see through, and my nipples always perked up and clearly left no wonderment of where they were, and it hung half way between my shaved pussy and knee. Underneath, I went with a thin white thong.

I went out to the living area and Mark asked if I wanted a drink. I accepted a whiskey and coke. There was a movie on TV and sat on the sofa and pulled my legs up on the sofa and crossed my feet. All my brother had to do was look, and he would see my white thong, legs opened innocently. As the movie played, I noticed he looked right at my pantie covered vagina several times, and his bulging pajama bottoms again sported a tent of unmistakable man meat. After the movie ended we decided to go to bed as it was late. We sort of met at the junction of our separate rooms and gave each other a goodnight hug.

I felt my tits press against his chest as we pulled each other in and hugged. We held on a good bit and it felt like electric sex. The vibes were strong, powerful. My pussy was literally tingling and aching as we stood there embracing each other. I could feel his hardness pressing against my womb. I could have been content with that and went to bed perhaps, but then his cock pulsed against my pussy mound. I knew that was not enough. I wanted to fuck my brother.

We eased our hug and when he looked into my eyes we both knew it. The old days were back, the feelings of wanting each other, to sin, to do incestuous things and it feels so normal to us, but is so taboo.

We parted and went into our separate rooms. I climbed into bed and my pussy was so wet and full of want for my brothers cock. I lay there for maybe ten minutes but had no choice, I got up and entered my brother's room. He was laying in bed underneath a sheet, head turned and watching as I closed the door. I walked over to his queen bed and he looked at me with a stare that said he wanted me too.

I pulled off my top and tossed it on the floor. He eyes grew big at how I'd filled out since he last held onto my perky tits at 16. I was a woman now. I slipped off my thong, and nervously whispered, “I dare you,,, to let me in”. My brother pulled the sheet away, inviting me into his bed.

I crawled into his bed and we wrapped ourselves around each other. My brothers body seems so familiar, although we'd not been together naked in 12 years. Our lips just met and we began to kiss and feel each others bodies. He grabbed my breast in one hand and held my ass cheek in the other while I had one arm around his neck and clutched his butt with other. We kissed with such passion and I felt it all the way to the depths of my dripping shaved pussy. We went savage, kissing and touching, building up a fire that could only be quenched with release.

“Touch my cock,,, I dare you” his words beat me to punch, we are twins and I smiled as I reached for his cock with the knowledge our thoughts were again those of brother and sister with a bond others don't understand.

I gripped his cock like I remember doing, giving it a hard squeeze. But this was the cock of man, big and thick, strong and hard. My brother had bloomed into a fine, man with a fine cock some 8 and half inches long and that wideness I recall from last we'd touched.

I stroked Mark's shaft, jerking him off slowly and reuniting with his cock. “Touch my pussy, touch me,,, I dare you” I whispered into my brothers ear. Instantly he sank a finger deep into my soaking wet, tight pussy. I let a moan escape my lips as I kissed his lips and he began to finger fuck me deep and rub my hard clit.

We were like animals, over taken with lust, almost driven by rage to mate, to fuck each other with abandon. I did not need a dare game, I quickly darted under the sheet and sucked my brothers cock into my eager mouth. I suck him solid, using all the skill every cock I'd ever sucked taught me.

His cock stretches my mouth wide, almost too much, but I have it all in my mouth and lodged in my throat. I stay for a solid minute, fighting off the impulse to gag. He lightly lays his hand on the back of my head and prays “Oh god”. He knows now, I've grown into a cock sucker. No longer that girl that did not know what she was really doing at 16. I needed him to know I was a woman, his sister, and I knew his body as well as my own.

I lick a path up his torso and straddle his waist then settle my 36c tits against his chest. As I kiss my brothers lips that fat cock pokes at me, nudging at my wet pussy lips, seeking to join it's wet counterpart. The meaty head spreading my pussy lips feels good. I can feel my pussy tingle, my wetness is flowing and ready. Mark's cock searches my slit, and finds the entrance to it's sisters body, but that's all. He won't go further.

He throbs in the wetness of my outer lips, stretching me wide and the tip of his dick sniffs at my hot tunnel that wants filled by my brothers dick. “Do it,,, I dare you” he whispers into my mouth.

I raise up on extended arms and in one smooth motion, I have all of my brothers cock deep inside my aching pussy. We both moaned the same cry as our bodies united in a feeling like we'd never experienced. He grabbed my butt in both hands and began to fuck me. Our bodies were on auto pilot and mirrored each others movements perfectly.

With each thrust of his hard cock into me I met it half way, and when I pressed down and ground my pussy on his body he'd already began the same motion, grinding our privates together “Cum on me Sissy” he said just as I began to feel I was close. Our thoughts were one. “Cum on me,,,, I dare you” my brother said.

“Okay” I say and my orgasm hit me like a Louisville slugger and I was a beach ball. My body convulsed and I jerked so hard I thought I may break. I cried out loud in his dark bedroom so loud the neighbors could hear, “I'm cumming on you brother”. I didn't need to whisper anymore, we were adults and alone and we had no shame.

“God Sis, your pussy feels so good” Mark say out loud. We both roll over at the same time, no need to wait for the other, we spun about in unison and he shoved my knees to my shoulders, folding me like a cheap taco and slam fucked me deep for what seemed thirty minutes. We kissed and our hands searched every inch of each other body. I repeated my orgasm three more times on my brother's steely cock. God he could fuck, and I met each thrust.

We were panting and sweaty, still in fuck frenzy when I said “Cum in me,,, I dare you”. He answer was instant, “I'm cumming”. I yelled out like hailing a cab “Me too, fuck, I'm coming again Mark”. He held me tight with his wonder cock pushed as far into my soaking wet pussy as it would go, and felt each pulse of his cock pumping his sweet hot cum into my depths.

We finally just collapsed, crumbled onto the mattress and into puddles of our fuck juices. We lay there a long while, catching our breath. No words were spoken, we both at the same time turned onto our side and we spooned. His arm around me, body pressed against my back side, and we slept.
