Unexpected Intimacy for Twin Sister

An unexpected event between me and my sister happened recently. Following a fight with my girl a few months earlier, I had left her and moved my things out of her apartment, taking everything to my sister Jill's home temporarily since she'd been kind enough to let me stay with her during my search for a new place to stay. Jill lived alone and offered to help until I could patch things up between Dawn and I or whatever.

Jill and I are twins. I'm a boy and ten minutes older than my sister. We came into this world twenty-three years ago and have always gotten along just fine, parting ways only as we hit our early teen years after losing our parents in a bus accident, following which the trustees packed us off to different boarding schools for our college years. This meant I didn't see much of Jill for almost twelve years. However, within the last year, we'd come back to our old city and now lived fairly close to one another.

As I soon noticed after moving in with her, Jill in heels is almost as tall as I am and with her thick, shoulder-length auburn hair, she's quite lovely. In hindsight, given my sister's looks, I'm not exactly surprised at what happened between us after I moved in with her but it sure changed our relationship.

Following my breakup with Dawn, I had found it difficult to go without sex since I was so often horny. Jerking off helped but was never completely satisfactory and I missed attaining my orgasms through female penetration. Once I started living with Jill, we were around each other all the time and I soon reached a point where, despite being her brother, I could not help noticing how sexy Jill was. I was increasingly horny, to the point I began to think of her as a potential sex partner, despite knowing full well how taboo this was.

As far as I knew, Jill had never felt anything like that toward me and, as I feared, she was extremely taken aback when I rather awkwardly broached the subject with her. This happened one night after dinner, Jill and I were taking care of the dishes and I asked her what had caused the breakup with her boyfriend.

Jill shrugged. "Oh, we're over each other, I guess. Why?"

Sis and I had never really discussed each other's love affairs.

"Well, I haven't seen Richard in quite some time, why did you two split?"

Jill just raised her shoulders. "We drifted apart, that's all. This new girl appeared at Richard's work and they hit it off, to say the least. I didn't mind much. Things had been kind of lukewarm between us and Richard's not exactly prince charming material so that's what happened. And I don't care. Satisfied?"

I came out with it. "Okay then, there's something I must tell you. Please hear me out. I, ah... I'm going out of my mind, Sis, I'm horny all the time." Jill opened her mouth but I didn't let her speak. "Listen... Please listen to me Jill, I want to fuck but there's a problem, I want this with you!"

Jill blushed, she dropped her wet utensils on the counter and covered her face with her hands, looking at me with an expression that clearly conveyed distress. She turned to leave the kitchen but I grabbed her and put my arms around her.

"It's okay, I would never force you into anything but I need it so much, because I think I love you. I was never able before to say this to you."

I could feel Jill sobbing in my arms, probably horrified after what I'd said. There had never been anything between us to indicate a situation like this could develop.

"What are you trying to say right now Tom?" she sniffed. "You can't be serious. Did you just ask me to have sex with you?"

"Yes, that's it. I need help. I'm going bonkers with need and jerking off is never enough. I need your help with sex. We're alone, it's just us. No one would know."

"Come on Tom, this is gross. Snap out of it" Jill squirmed out of my arms and picked up the utensils again and we sort of finished the dishes.

"You're right, Jill, I know, but why not? Why couldn't we have sex, I need it and you could help me. You're the most beautiful girl I know and so sexy it hurts. It's not as if you would get hurt or anything. Don't you enjoy sex?"

"You seriously want to fuck me?" Jill looked at me with tears in her eyes.

"Yes, I do. There needn't be anything serious between us, I just want to do this with you and finish quickly." I took Jill's hands in mine. "When my dick gets inside a woman, it's like heaven. You're a woman, Jill, you're beautiful and I need to fuck. Fuck you."

"This is nuts." Jill stood in front of me and I could see anguish in her eyes. "You wish to fuck with your own twin?"

"It wouldn't take long..." As I said it I knew it my answer was the lamest... Jill looked me in the eye then turned around and headed for her room. I'd messed up badly and prepared to spend the evening alone with the TV.

Two hours later, Jill went to the bathroom and I heard her take a shower. When she came out and headed for her room, she said: "Tom, move your ass, get in here and do me quick, before I lose my nerve."

The room was dark. Jill was lying in bed, under a sheet but apparently nude. In a daze, I stripped and joined her under the sheet. My cock was hard as I moved over her, took hold of my dick and pushed it hurriedly in my sister's love tunnel. I grabbed her hands and held them up by the headboard as I fucked her. I didn't last long but my orgasm was hugely gratifying just the same. But I guess realization with what I'd done hit me at that point because I immediately got to my feet, grabbed my clothes and left Jill's room. She came out after a few minutes and went to the bathroom then came into the living room, almost as if nothing untoward had just happened.

"Jill... I don't know what came over me."

Jill sat beside me and reached for my hand. "It's all right, Tom, and you can come back to my room later. It'll be fine, I know this was too quick and not the best."

We watched the movie until it ended and didn't talk about what we'd just done. Jill went back to her room but turned to me at the door. "Remember what I said."

A few minutes later, entering Jill's room, I saw she had disrobed and lay nude on her bed. The light was now on and I had a good look at her shapely body this time as I feverishly got rid of my clothes then got on the bed and moved between my sister's legs. She raised her head and looked at my hard dick as I slowly entered her. She fondled her nipples as I plunged into her repeatedly. I had thought I should fondle her tits but decided to wait until she asked. My orgasm surged quickly but felt amazing and I quickly got up to leave. As I made my way out of the room, I looked back at my sister. "Fucking has never felt better than just now inside you, if you want to know."

The next day, a Sunday morning, Jill got up late and pecked my cheek as I prepared coffee. She was beautiful, as usual, and I desired her the minute she came into the kitchen. "So, how's my potent male kin doing this a.m., relieved?"

I poured some coffee and handed it to Jill and kissed her back, a quick kiss on the mouth.

"Your male half is feeling generous this morning and will gladly let you partake of his sexual ardor, dear temptress. So, drink up! Ogling your sexy curves and inhaling your female scent does tricks to my dick and it signals an urgent need for friction inside your tight pussy. So, I must have a quick go at you right away, before we eat."

When I penetrated Jill's body moments later, she moaned softly and I felt her body twist and stretch with what I hoped was lust for me as, for the first time, she moved her hips to meet my thrusts as I slowly fucked her. I lasted longer that third time and found our coupling very pleasurable. My sister's sex felt sufficiently lubricated despite my repeated failures to provide her with any kind of foreplay. She had beautiful breasts and I resolved to play with them during our next sexual encounter.

Jill did not resist me later that afternoon when I said I needed to fuck her and I could barely believe my luck. I began by fondling her tits this time around and I kept it up until I felt she was ready to beg me to get inside her. Then I fucked her hard and we came almost together. This was less than twenty-four hours after I first asked Jill for sex. I think she was starting to like the feeling of my thick prick making its way inside her. By this time, Jill's room smelled strongly from our sexual encounters so I opened the window. I got back in bed with Jill and we just rested for a while, our bodies always touching. I wondered why I hadn't felt drawn to my beautiful twin sister earlier but I suppose it was because of the old taboo about not desiring your sister.

Well, too bad. I no longer care. I'm making up for lost sex occasions and the next few months will be a very exciting, sexy time for me and my sister. I am now able to last inside Jill long enough for her to start getting orgasms just from fucking and she sometimes enjoys playing with her clit as I fuck her. We have yet to try oral sex with each other but I plan on going down on Jill soon. Then I'll ask her for a blowjob, I'm looking forward to the feeling of my dick being inside my sister's hot mouth and the feeling of her tongue twirling around my dickhead. I don't know how Jill feels about swallowing cum but I'll find out soon enough. It'll be fine even if she doesn't give me head. I love my sister and anything sexual feels good with her.

That's where things stand. If anything, my love for Jill has increased since we've been making love. If she feels as I do, she won't be looking for a new lover anytime soon. I suppose I'm in love with my sister and she says she loves me too. So, we'll remain together. We're twins and our love feels sweetly natural.
