I stood there speechless, but my cock began to swell in her hand.
“Ohhh!” She said smiling, feeling the growth she created. “I see someone is interested.”
She leaned forward again, this time she placed the whole of my cock in her mouth.
“Oh fuck!” I said my hands instantly going to her head for support. She looked up at me, smiled and began to suck.
Her skill was unique, not like our mother’s but talented none-the-less. In no time at all, she had my cock up to a full throbbing erection. She pulled herself off and jacked my member, smiling up at me the whole time while I heard the clicking of shutters as my mother captured the whole event.
“I bet you want to fuck me now, don’t you?” she said scrunching her nose.
She leaned back, showing me her sopping cunt as she began to finger herself again, all while stroking my cock.
“You don’t know how horny you two made me. How fucking hot it was watching the two of you. And you know what? You taught me something about myself. I like to be naughty. I like dirty, nasty things. I like watching a mother fuck her son. I want to fuck my brother. I might even fuck Daddy someday. But what I really want to do right now… Is be dirty. Really, really dirty.”
She leaned forward again, licking the tip my cock.
“So now, I want you to fuck me…. but not in my pussy.” She lifted both legs on the armrest rotating her hips up. “I want our first time to be in my ass.”
It took a few moments for what my sister said to register in my mind. I looked to our mother for support, but she was too busy snapping away at the camera offering no means of advice.
“Come here brother,” she said, pulling me down by my cock. I felt horny and helpless, all rolled into one as she positioned me at her tight little rosebud.
She let go of my tool and then reached behind me grabbing my ass and pulled forward, urging me into her. My dick was lubed with her spit and ready for entry into the tight crevice of her asshole. She clenched her teeth as her sphincter opened allowing the head of my cock to pop inside.
I have never had anal sex before, every girlfriend or one night stand was repulsed or never even showed any hint of interest. Yet here I was slowly easing inch after inch of my shaft into that taboo of taboos; and she was begging me for more.
“Oh My God, I can’t believe my brother’s in my ass.” Her teeth remained clenched as she began to rub her pussy with her free hand. “Oh fuck, keep pushing Jason.”
Slowly, I obliged.
“Come on Big Brother, I want you balls deep. Give me all of it!”
She was tight, tighter than anything I had experienced. It was so different, and so unbelievably naughty. I never expected her to be so kinky… and yet, though it was my first time, it slipped in easier than I would have thought. Slower, but easier. I believe she sensed my confusion.
“Bet my ass feels good around your hard dick. I lubed up my little hole while you and mommy were going at it. Now stop teasing me and-”
Her eyes went wide with a long, primal groan I pushed hard into her in one determined thrust. I felt my pelvic muscles pressing against her pussy, my hairs tickling her lips.
