I took a swig of my beer, and nearly spit it out with her next statement. "Your sister is pretty hot, even if she is mad at you. I wonder what it woul... be like to sleep with your own sibling?" Her laugh grows stronger by the look on my face. "Relax, I don't judge. I actually think it is kind of hot." I can't believe this lady is being so coy and honest with me. I can even feel myself getting hard as she talks, and notice that her nipples are starting to poke through her top."How did you figure. I began to move more confidently and she approved a little more powerfully each thrust and then a stabbing lunging force inside her produced tight contractions forcing me out ward until I slammed roughly back against them a****l thrusting her extreme pleasure shook her body and she laughed uncontrolled as she craved more and for longer. I was in no hurry to climax and varied the speed and angle that went in deeply to her moaning lack of control, her panting laughing monosyllabic "yes" repeated.

"You hardly know me," she said. "You don't have to do this." Yes I do, for your mum's sake at least," I replied.I. .. Yeas ... Uh-huhhhhhmmmm..." I sighed."It's almost six-thirty. You're going to be late for school," she told me, like I didn't already know that someplace in my head. I just couldn't remember where."Ummmm ... Lick ... Lick ... Me ... Ahhhh..." I had to moan then. Maybe loudly too, because like I said, the whole world was turned way down ... except for me."Tiffany?" More rapping. "Are you okay?" Oh!" I gasped, breathing hard and blinking at my mom as she opened the door."What's the matter?".
