How I Became Big Sister's Sex Slave

... sucking cum out of your big sister's asshole," Karen moaned. "That's it, stick your tongue in real deep, make sure you get it all. " After awhile Karen stood up and smiled at me. "You did a real good job, little bro. You've earned your reward. Ok, go ahead and spread your legs wide apart." I did so and Karen crawled between my legs. I gasped with pleasure as I felt Karen's warm hand close around my dick and begin slowly pumping up and down. "Mmmmh, doesn't that feel good Brian? You like the feeling of your big sister's hand stroking your hard cock? Do you?" "Yes, yes!" I stammered. "Yeah, I thought so. Then you're gonna love this." Karen ran the tip of her tongue all around the head of my cock, licking at the piss slit and tasting the pre-cum that was flowing out of me as she continued to slowly pump up and down with her hand. I moaned deeply and arched my back. "Ohhh, God, Karen that feels so good!!" Karen glanced up at me again with that arrogant smirk on her face. "What do you want little brother? Do you want to cum? Do you want to feel my lips around your cock as you shoot your load into my mouth?" Weakly I gasped out, "Yes."

It felt so incredible, and I knew I couldn't last much longer. Looking down at my sister's head bobbing up and down on my hard shaft I felt my ball sac tighten and my toes begin to curl. "Oh, shit, yeah, oh god, Karen, I'm gonna cum!!!" Karen took my cock deep into her throat, swallowing reflexively as I shot blast after blast of hot cum into her mouth. Finally I lay back, panting for breath, my eyes half closed in delirious oblivion. My sister crawled slowly up my prone body, dragging her hardened nipples against my chest, sliding her beautiful tits against me. Our lips met in a long, delicious kiss, and as Karen's tongue slid into my mouth I tasted the salty bitter flavor of my own cum. "Did that feel good, Brian?" "Oh, shit, Karen, that was the best orgasm I've ever had!" She smiled. "Yeah, well it sure as hell won't be the last one. We've got all summer, and I have definite plans for you, little brother."
