Faternal Twins With Benefits

All sexual participants are 18+. No person, living or dead, is present in this fictional story.

I didn't hate my twin sister. I didn't love my twin sister. Once we turned 18 I just fucked her.

I'm Nathan French and my twin sister is Francis French. Of course, we're known as Nate and Fran. We are 22 years old as of this writing, just graduating from college.

We had an older sister, Caroline, who developed osteosarcoma in her leg when she was 13 and we were ten. It was a painful three years for the family until she lost the battle. For those three years, Fran and I were as close as twins could ever be. When Caroline passed away, we were stricken and even closer.

Even as young as we were, a lot of things died with us in addition to Caroline. We lost faith in our parents, who we believed didn't do enough to keep her alive. Of course, we were totally wrong. Doctor and hospitals - obviously. We never regained any trust in them. God: We felt as abandoned as the Jews in the boxcars to Auschwitz. Maybe we're wrong, but we lost faith forever.

That left only us. The amount of tears we spilled on each other's shoulders would fill a bathtub. Being young, it didn't take very long to start recovering. We had been close before, but now we were inseparable. Maybe that's when we fine-tuned the twinness. We could easily know what the other was thinking, finishing sentences for each other.

That ability came with a cost. We lost the ability to love. That included each other. Oh, we felt great affection towards each other and some for our parents, but never that I'll-give-my-life-for-you type. From the time we were 13, we existed in a world that never included the mountains and valleys of love.

By the time we got to high school we were set in our emotional world. In our physical world, I was exactly six feet tall and a skinny 145 pounds. Dark hair and readily tanned skin. My rather large ears knocked me out of the running for handsome. Dark brown eyes and a scar on my forehead (falling out of a tree) pretty much described me. Close to ordinary, I wouldn't stick out from the herd. I was very good academically and not-so-good athletically. Never the last one chosen, but never the first.

Fran was a female version of me. She, too, was six feet tall and only 10 pounds lighter. Small tits and ass. Dark hair, brown eyes. Her ears were normal and until you saw her smile, she would also be one of the herd. But her smile! Never had I seen such a transformation from ordinary to extraordinary as when she smiled. Not just her lips, but her eyes and whole body participated in it.

Guess I was wrong on one thing. I loved her smile and would do almost anything to see it. Alas, it wasn't unsheathed as much as I'd liked it to be.

Fran was at the same level academically as I was. She, however, was also a good runner and was on the track team. I took in every meet. Don't remember the parents ever being there.

My interest was in rocks. I was an avid collector and filled my room to overflowing with what I found and could afford to buy. Fran shook her head, but she helped me when we had a chance to collect. There was never a doubt about my career path.

We rarely dated all through high school. Neither of us was shy nor did we have difficulties in dealing with the opposite sex. We just didn't feel like it. Now, of course, hormones did hit us like an earthquake, so evolution did push us towards sex, but something was just holding us back. We weren't asexual.

It finally came to a head one Friday evening in our senior year. We had turned 18 six months before. It started out like many Friday evenings. We were watching TV, the parents out playing bridge till late.

I turned to Fran, "Another Friday. Glad classes are over for the week... Have much school work to do this weekend?"

"No, nothing. You?"

"Nothing, either... I'm a little bored. Want to go get an ice cream?"

"No thanks. Bored here, too."

"We do this a lot, don't we?"

"Yeah... Maybe I'll just go to my room and play with my pussy."

"Not a bad idea."

"What? Going to my room or playing with my pussy?"

"Both sounds good to me."

She looked at me to see if I was joking, "Seriously?"

"Why not?"

"Where's this coming from? We've never done this before."

"So? I'm going to jerk off and so are you. Why not together?"

She thought for a moment, "What exactly are you proposing? That we get off together or that we get each other off?"

"Well, both sound good, but if I get a choice, I'd pick door number 2."

She thought for a moment, "How about a little persuasion first? Kiss me."

I leaned into her and covered her mouth with mine. I'd kissed girls before and I knew she had kissed boys, so we weren't tentative. Her mouth was sweet, and her tongue immediately touched my lips. We traded tongues and breath for several minutes. "Is that persuasion enough?"

"Think we need a little longer..."

Somehow, it never really entered my mind that I was making out with my sister. It was like it didn't make a bit of difference that she was my twin.

We sat on the sofa and made out for maybe 30 minutes. Have to admit it was exciting and it was obvious we wanted more. I ran my hands around, trying to get re-familiar with her body. We had never been shy around each other and had often touched. However, that stopped a few years ago in the puberty tsunami. I explored her little breasts on the outside of her shirt and bra, her ass through her jeans.

She stood up and took my hand. We went upstairs to her bedroom. She pointed to a chair and said "Sit."

She took her place sitting on her bed. We just looked at each other for a moment, not sure how to start. By our twin connection, I knew that we weren't ready for anything complicated. I stood up and took off my jeans. She did likewise.

We took one final look at each other's face and both dropped our underwear. As can be imagined, I was hard and pointing at the ceiling. Her bush was a dark mass of curls. Neither tried to cover up. We simply looked.

She said, "I usually look at porn when I do this."

"So do I... Don't think I need it now. Do you?"

"No, definitely not. You're not even touching yourself and I'm wet as a sponge."

My hand immediately went to my cock. I started to slowly pump. She, meanwhile, covered her pussy with her right hand. It was apparent that her middle finger was no longer on the outside. She pulled up with it, exposing a line of pink on either side. When she repeated the action, it was wet pink exposed.

I quickly had the glans covered in precum. Her pubic hair was getting saturated in moisture. Her fingers separated further, going to the side of her vulva. She pressed down and her vulva emerged from the forest. Two eskers defined her split leading to a moraine that was her clit.

Needless to say, my cock got even harder at this erotic display. She pulled her middle finger from her depths so she could stroke her clit with the pads of her finger. Her inner lips were visible on the upstroke. Her eyes were clamped on my cock, as were mine on her hand.

In my imagination, I could smell her essence, although I was too far away to really smell her. I was sure that soon we would be close enough for me to taste it.

We were both moving hands faster and breathing deeper. I knew it wouldn't be long before I came. The muscles in her thighs were tightening, becoming long ridges under her skin. Her toes were alternating pointing straight out and curled up. Her palm was pressing harder on her pussy, flattening the hair. Her finger was moving in its mission. Her legs were spread and exposed her butt.

Meanwhile, the flow of precum oozing out of my cock increased. It spilled out and ran under my fingers. I felt my climax start from my toes. It ran a race to my cock. I couldn't stop it by squeezing my hand, "SHIT!"

A stream of cum shot towards her, not quite covering the full distance. A couple of drops hit her extended feet. She reacted as if the drops were burning napalm by cumming hard. She didn't say anything, but she stopped breathing for a few rapid heartbeats then gasped. And gasped again. And gasped as if she had been pulled from a burning house.

Not too surprising we didn't shout out our climaxes since we've been conditioned to silence for as long as we've been masturbating.

We both sagged down as if the bones in our bodies had turned to soup. My eyes met hers. I read the same thing she read in mine: lust. We knew this wouldn't be a one-time thing and that we'd escalate it.

"I hope you enjoyed it as much as I did."

She gave me the smile that launched a thousand ships, "Probably better."

"How often do you do it? I'm usually at twice a day."

"Once or twice... Have to admit that if it was as intense as what just happened, I'd want it 10 times a day, but that would probably do me in."

I could only nod my head in agreement. We would probably have gone another round, but we figured the folks would return soon. Their bridge sessions were variable, depending on how many couples showed up. They probably wouldn't come upstairs, just called out their return and expected an answer, but we couldn't be sure.

We got dressed and went back to the sofa. Without thought, we sat down next to each other, actually touching. I figured *What the fuck? Why not? * Reached down to put my hand on her upper thigh. She didn't even look at me as she put her hand in a congruent place on my leg. We simply started rubbing legs. Took me all of one minute to reach the crotch of her jeans. She put her hand on my rapidly rehardening dick and rubbed up and down.

Of course, the front door opened, and the parents came in. Our hands returned to safe territory, and we created a little space between us. I was sure we'd resume after they went to bed. They complained about the low turnout and Mom had a headache. So, they were off to bed.

We stayed up for another 30 minutes before heading to my room. As soon as we closed the door (no locks), we were in each other's arms kissing like we'd done it our whole lives. We didn't keep it up very long before simultaneously discarding out jeans and underwear. This time we sat side-by-side on my bed, legs in contact. A little more kissing and my hand tunneled into her forest while her hand had a firm grip on my erect cock.

Since she had watched me, she needed little instruction in how to move her hand. I just had to tell her how hard to grip it. Meanwhile, I was a babe lost in the forest. I cupped her vulva, pressing on it and rotating my hand to grind on her. She was getting stimulation because I was rubbing her clit, but she wanted more, "Put your middle finger in me. Don't push it in like you're trying to get the last of the jelly. Lay it parallel to the lips and bring your whole finger in."

She was very wet, and my finger easily slid into her as far as the labia minor, "OK?"

"Oh, yes! Move your hand up and down, rubbing my clit and caressing the inner lips... Oh, shit, just like that."

We ended the vocal instructions as we were having a hard time talking. It wasn't perfect for either of us, but it was certainly good enough. We kissed more urgently, reflecting our hand motions.

Wow, could I smell her essence! It caressed my senses like it was a tangible object. I stopped briefly, to her displeasure, to suck my middle finger. She opened her eyes to see what I was doing. They lit up. She knew what our next advance would be.

I returned to her forest which quickly became a swamp. Her face got flushed, and a pink area advanced up her exposed chest to her throat. Neither of us had the breath to resume kissing, and found panting was more comfortable. I used my other hand to touch her neck. Ran my fingers from her ear down to where it met her shoulder. This caused her to shiver, but didn't interrupt her work on my cock.

The glans of my cock was getting very wet with precum, "Use your thumb to spread the slickness."

She spread the moisture over the head and down the bottom side. The added slickness was a big turn-on. Her grip was perfect - as if she could read my mind.

I crooked my finger in her slit so that it went beyond the inner labia. Not far as I knew she was a virgin and I didn't really know where the hymen was, other than it wasn't very deep. There was a pool of soup there at the bottom that spilled out when my finger opened her labia.

She had a look of compete concentration on her face. I probably did, too. Her thighs were compressing her labia, so I had a hard time moving my hand. She recognized this (More awareness than I possessed.) and opened them up. I think every muscle in her legs was involved. Her quads got as rigid as guywires, long, lean cables that showed she was a runner. Her feet and legs were pointed straight out like a ballerina doing pointe.

Since I wasn't a runner, there wasn't as much definition in my legs. They were tucked back under the edge of the bed, my groin trying to thrust up to expose more of my cock to her hand.

The feelings were exquisite. We touched all the time, but this was so different. It was the first time I felt her. Can't really say what the feeling was because it wasn't describable. The only thing I could say that it was condensed lust. Pretty sure it wasn't love, but that didn't make it any less intense.

We were so excited that it couldn't keep going very long. She went rigid. Her whole body a single plank. Juice flowed out of her pussy, and she had a difficult time catching her breath. Seeing this my cock without any instruction from my body took over and I ejaculated a tower of white cum. I could almost hear it splatter on the floor.

Conditioning held and neither of us screamed out our joy. It was clear we would be repeating this frequently. And we did.

One side effect of our activity was that we dated even less than previously. Didn't seem to be any reason to date.

Our parents were thinking ahead, though. Two months before the prom Mom put Fran on birth control pills, "Why now, Mom?"

"Everyone knows that after the prom activities frequently involve sex and it takes a while before the pill is effective, so just to be safe..."

"I haven't even been asked to the prom and not sure I'm going."

"Won't hurt you and will keep your periods regular."

So that was how Fran became safe. It was food for thought even though we hadn't progressed beyond mutual masturbation. We ended up not going. Not that the prom night wasn't useful.

Because we were staying home the night of the prom our parents decided to have a date night of their own. They left for an early dinner and then went dancing. They connected with another couple, "We'll probably be late. We've left you some money so you can order pizza and enjoy a quiet evening."

Our parents' interactions with us were kind of strange. They were concerned with Fran getting pregnant, but on the other hand seemed unconcerned that we skipped prom and did little dating.

The pizza was on order before they got to the end of the block. We started looking for movies while we waited. Seems everyone was going out, so there wasn't a long wait for the pizza. We still hadn't found a movie that both of us wanted to see, so after pizza we just said, "Let's go upstairs."

We went to my room. Normally, when we masturbated, we just removed our clothes from the waist down (in case we got interrupted). Now we knew there wouldn't be any interruption. After kissing for a while, we stripped completely. We first just stood there looking at each other. I had never seen a fully naked woman in the flesh. She was beautiful, "Wow! You're absolutely gorgeous!"

That brought her smile. The combination was overwhelming. My cock was so hard. Harder than it had ever been. It felt like there wasn't enough skin to contain it. Her breasts were small, and the nipples erect. Looked like they were as hard as my cock. They weren't very thick but were at least three quarters of an inch long. Think they were longer than breasts were. Maybe my drooling was only in my imagination...

Her eyes were initially focused on my cock but quickly drifted over my whole body. I didn't have much chest hair, just a few curled around my nipples. Since I was fairly thin, there was a considerable definition of my abs. I hoped that I looked OK. She seemed happy and her smile broadened.

We closed the distance so that it was flesh on flesh contact. I regretted not having her turn around so I could see her ass, so had to be content with feeling it. As I expected from her running, it was firm. No excess padding, each cheek just a good handful. We explored whatever we could reach. When we felt satisfied with our knowledge of the territories, we fell together onto the bed.

I rolled off of her, so we were side by side. Now I could feel her tits and smooth abdomen. It was also the first time I had been able to see the full extent of her pubic area. The line of dark hair extended all the way to her bellybutton. A passing thought: that part would need to be adjusted when the swimsuit made its appearance. Her tits were small, especially now when they barely drooped off her chest. I learned later she wore an A-cup.

I knew enough without her giving me instructions, to start playing with her tits. Her skin was warm and smooth till I got to the nipple and surrounding terrain. The nipples drew most of my attention. I caught the right one between thumb and forefinger and pulled up, making it longer. Repeated with the left one. They were as hard as possible, like my cock. Bent over, my lips latched onto the right one. I alternated between them. Leaving them in a thick coating of saliva. She pushed me off and started sucking on my nipples!

Never thought my nipples were an erogenous zone, but she made me a believer. Her scent filled the room, so as she sucked I reached down to her pussy. It was definitely wet.

We knew that we wanted to taste each other, to bring the other off with our mouths. Neither of us wanted to relinquish our pleasuring of the other, so by twin-thought we rotated into a 69.

We lay side by side and she put a leg over my head to allow access to her pussy. I thrust my groin forward to allow her to take the head into her mouth. Her scent was overwhelming from a range of two inches, one inch, bingo. The tiny tastes I had enjoyed from licking my fingers were molehills to mountains. I went crazy licking everything within reach. From our earlier handling, I knew exactly where her sensitive parts were, so attacked them in earnest now with my tongue.

She, meanwhile, had enveloped my cock with her mouth. I thought I had entered one of those cavities in the lava that led to the molten heart of the volcano. Of course, our only knowledge of oral pleasure was through porn. Guess we knew enough that neither complained. Our biggest problem was restraining ourselves. I wanted to push my cock all the way to her feet. She wanted to flatten my face with her pussy, leaving only my tongue in her hole.

We attacked for what seemed like seconds, but it was surely minutes. Her pussy and my face were awash in her fluids. I poured out precum and the excess saliva made my cock super slick. Her hand moved with skill and determination, coordinated with her head motion. Her mouth, on fire, set my cock on fire! Her tongue explored every part of my cock. She couldn't reach the base, but that didn't make any difference in the electricity flowing from her to my cock. No way could I last. I fired a monster load into her mouth. She stopped moving and backed off far enough to have room for the fluid that she was trying desperately trying to swallow.

The momentary distraction allowed her to hold off her own climax. I redoubled my attack on her clit, pushed the jungle of hair aside. This accomplished the goal. She came, a river poured out of the bottom of her pussy and ran down her leg. I vowed that next time it would flow into my mouth and onto my face. If she said anything, I couldn't hear as her legs tightly covered my ears.
