How, you ask, did I happen to be taking a bath with my eighteen year old twin sister? Well, being twins, we were always close, though our mutual bathing had stopped once we hit puberty. Our parents always made sure we weren't TOO close, since as young children we would often be naked together or using the toilet while the other one was in the bathroom. But even our parents couldn't keep us from playing around with each other when the mood hit.
Usually the games we would play were pretty childish. We would show each other our genitals, since we each had a mutual curiosity. We had seen each other naked as toddlers, but as we matured we became interested in seeing how the other person changed. Of course, that only lasted until we were about fourteen, and we seemed to lose interest in our games. I had not seen my sister naked since then.
But one day, when our parents were gone for the day, I was taking a bath since our shower was broken. I sat there in the hot water, just having filled the tub, when there was a knock on the door.
"Can I come in?" my sister asked.
"Yeah," I said, trying to cover my crotch with my hands.
She opened the door and left it open as she lifted the lid on the toilet and dropped her panties. She smiled at me, her eyes drifting to my crotch. I was at the perfect angle to see her neatly trimmed crotch as she was taking a leak. I felt my dick twitch, and she saw me staring at her vagina. She finished peeing and lifted her hips a bit.
"Get a better look," she joked.
I was embarrassed, and sheepishly smiled. "Sorry."
"Well, come on," she said.
"What?" I asked.
"I let you see my pussy, now show me your dick."
I nervously removed my hands from my crotch, and realized I had an erection. She smiled and tried not to laugh.
"Geez, I didn't mean to make you so horny," she said.
"Well, what did you expect? I haven't seen you naked in years."
She stood and took off the rest of her clothes, to my surprise. When she removed her top, I realized how much her breasts had grown. She was at least a C-cup. Her small nipples stood out from her firm globes. She stepped into the bathtub and sat across from me. It was a large tub, but we were still sitting very close.
"I remember those games we used to play," she said, as if sitting there naked with me was nothing out of the ordinary. "It looks like you've gained a couple of inches since then."
My dick was still on display, but I wasn't going to hide it now. She stared at it, and her hand roamed over her stomach, and then to her chest.
"God, I'm so horny," she said.
"I don't have to tell you I am," I said.
"Yeah, I'd say you're ready for some action," she said, and to my shock she grabbed my dick.
I jumped as her fingers wrapped around my shaft. I couldn't believe this was happening. But before she did anything else, she turned around and leaned back into me. She nuzzled her back against my chest, and pulled my hands to her breasts.
"Massage me," she said.
I was temporarily distracted by my dick pressing between her ass cheeks, but the feel of her tits soon overtook me and I went to work gently feeling her up. She moaned, and flexed her buttocks around my dick. I thrust into her gently, and she smiled.
"You horny bastard," she said. "Don't you know the difference between pussy and ass?"
"I do, but my dick doesn't," I joked. "A hole's a hole."
She tilted her head back and kissed my chin. "Let's give your dick a little relief."
At the most I thought maybe she was talking about giving me a handjob. But instead she pulled her ass cheeks apart and I felt her hot hole touch the head of my dick.
"You really want to?" I asked.
"The hot water is very relaxing, let's take advantage of it."
Her asshole was surprisingly relaxed, and my head sunk in quite easily. After I was about an inch in, she tightened and we sat there for a while, so she could get used to the feel.
"What does it feel like?" I asked.
"It feels naughty," she smiled. "But really good."
Even though the water was not a very good lubricant, I found it surprisingly easy to sink into her. I pushed a few more inches into her, and after a few minutes I was buried as far as I could go. I held her tightly on top of me, my dick completely inside of her ass. She groaned and writhed around, my hands massaging her tits. She frigged her pussy while I was still to the hilt in her ass. In less than a minute, I felt her ass clench around my shaft as she climaxed. It was incredibly tight, as was her contorted face. She kept rubbing her pussy until her orgasm had passed. She let out a long breath, resting her body against me.
"That was fucking incredible," she said, her breath very intoxicating on my neck.
I grabbed her hips and began sliding in and out of her ass. As I did so, she let out wonderful sounds of sexual pleasure. I stuffed her ass nice and hard, and she was loving every minute of it. I felt orgasm approaching, and thought I should see where she wanted me to cum.
I leaned close to her face.
"In my ass," she said before I could say anything.
I smiled and continued humping her butt. Before long she began cumming again, and when her ass clenched around me, I blew hard. I spasmed into her more powerfully than I ever had in my life. I sent spurt after spurt deep into her bowels. Her orgasm lasted through mine, and after we were both finished, we sat there in the tub for minutes in silence, except for our breathing.
"God, I never thought it would be that good," she said finally.
"You're so fucking hot," I answered.
She turned her head and kissed me on the lips. "Did you like my ass?" she said sexily.
I nodded, and flexed my dick inside of her.
She giggled. "Go again?"
I happily nodded. "In the ass?"
So, again we fucked. I took me much longer to cum, of course. She had three orgasms before I came, but when I did it was heavenly. But by now we were both spent, and the water was getting cold. I finally pulled out of her ass for the first time. Her ass was leaking my cum. She put a finger up her asshole and rubbed the cum around inside.
We dried off and went to our parents' bedroom. They wouldn't be home for a good few hours, so we rested and played around with each others' naked bodies. Since I was still not getting hard, I ate out her pussy. I didn't know what I was doing, but she seemed to be loving it.
"What if Mom and Dad found out?" she said, while I was still eating her out. "What if they walked in right now and saw us doing this? We're so nasty, so fucking nasty."
She was dirty-talking herself to a good cum.
"Brother and sister fucking each other, what would they say? Does my pussy taste good?"
She began a constant whine, and her orgasm overtook her. She bucked her hips and writhed in ecstasy, and while she was cumming I stuck a finger up her ass. She screamed and her back arched off the bed. Her head tilted back and her mouth was open in a silent scream. After a good minute, she was panting and rubbing her body all over.
"Fuck me," she said when she got her voice back.
I got on top of her and plunged my rock hard dick into her pussy. I'm sure I broke through her hymen in my first thrust, but we were both so sexually high that she didn't seem to register it. We were humping and fucking at an incredible pace. Suddenly we were both energized and I felt like I couldn't get enough of her pussy.
Our sweating bodies were intertwined, her legs wrapped around me and pressing me into her. She came twice, and I didn't relent in my pace while she orgasmed around my dick. When I finally reached my orgasm, neither of us had thought for a second about protection. It wasn't until after I had sent my ropes of sperm into her that the thought crossed my mind.
We just stared at each other, knowing we were thinking the same thing. It was too late to do anything about it. We just stared at each other for a while until we rolled over and she was on top of me, my dick still inside of her. She laid on top of me, her head resting against my chest. The question hung in the air...What if?
