" Is fucking fun?" Of course it is." Would I be fun to fuck?" Shit, yes," he said, grinning."Then will you fuck me?" she excitedly asked, her eyes glo...wing with lust."I wish I could," he sighed. "But that would be impossible." Why?" Because you're my sister." So what," giggled Marci. "I've got a cunt, and you've got a cock. Isn't that all fucking takes?" It's not that simple," he explained. "Fucking your own sister is incest." I know that," she pouted. "But I want to be fucked." Then start out. I like large cocks. You eat pussy?"I didn't, but since this was going no place I said, "With the best of them." Any man of mine will have to be damned good at it. By the way, I'm promiscuous as hell and my guy is not only going to have to be able to handle that, but he will have to eat my pussy when I come home freshly fucked. You think you can handle that?"Yeah, sure, right I thought, but I said, "Depends." Depends on what?" I don't care all that much for mixtures. I like the cum I eat to have. Turning to watch, I eventually stood up and as I faced her, she foxily crawled to the middle of the bed, seemingly suggesting for me to get on the bed too. Smiling, I cast the covers back a little and as I leaned onto the bed, Maria seductively smiled. Climbing on the bed with her, we ended up kneeling and as we faced each other, I put my hands on her waist. She really was pretty and as I leaned into her, she closed her eyes and as we kissed, she put her hands on my waist too. Maria then subtly. Gently massaging my walnut and working my glans he brought me back to full erection. This time they both took turns on me, sucking and working my cock aggressively and massaging my prostate with first one and eventually three fully inserted fingers. Once again at full erection they found my sensitive spot under my pee hole and worked it and my prostate until I exploded again. I slumped back in to the sofa and let out a groan. At that point of total surrender both Bill and Al sat close next.
