Then she closed the door, and I returned to my seat on the couch.I closed my eyes and tried to imagine her there in the bathroom, taking off her cloth...s, stepping into the shower... I heard the water turn on, and tried to picture it running down her hot little body. I wanted so much just to run in there right now, rip off my clothes, and make passionate love to her. This is crazy, I told myself. She's your cousin. And she's underage. You could go to jail for that. But I let my fantasies. To my surprise she said "Well if your so grown up, can I see it?", "When its hard I mean." I was shocked and replied "No way you can't see it", "your my sister!" She said "come on, if you want I'll show you my tits, I've seen you trying to take peeks at me getting ready in the morning." "What!" I said in desperation, "I have not." At this point I was wondering why I was lying about this when she was giving me a chance to live out my fantasy. She continued to plead with me, looking so cute. He was fucking me so hard and so fast. I felt like such a slut, and I loved every minute of it. “Oh fuck. Fuck me harder and faster Jack. I’m your whore, and I love your cock. Oh God it feels so good. Robert, it feels so good. I’m actually getting fucked hard and fast.” “Your pussy feels so good. You’re a fucking whore. Your husband is sitting there stroking his little puny cock. Look at his cock baby. Look how small he is.” We both giggled at Robert’s cock. His cock was just so small. Jack. "Someday in the near future, I'm gonna put a baby in it." She hissed, as a shiver passed through her. I jammed my rampant dick into her in one shot and started fucking her as hard as I could. Where we'd been gentle and loving in the bed, this time we were brutal. Each thrust almost lifted her off of her feet.The squishy sounds as I rammed her wet pussy were louder than the sound of the water falling on us. Her squeals were evidence of the fact that she loved what she was getting. After every.
