It was cramped and I lost my privacy, but I certainly wasn't complaining. Having that sweetheart around had my balls working overtime.One day after Ka...ren went to class, I decided to take full advantage of the privacy with a nice jack off session. I stretched out naked on the bed, greased my cock, closed my eyes, and tried to picture myself fucking my sister. I was pleased with the mental image I managed to conjure up. It was the best one yet. Having her around had refreshed my memory of her. "Bitch… you are a good cock sucker… you are a crazy slut…” The sight of my own spit coating that monster cock and my red lipstick all the way down at the root of it made me smile and feel wetter... Standing up, I leaned over the sink and looking up into the mirror I told him: "I want to feel your huge dick in my pussy… could you do it for me…”?The young black guy laughed as he stepped up behind me and quickly put the fat head of his cock against my wet open pussy lips…I felt him stretching me. ”And with that he left.After he left the room the rattle in her vagina started to buzz. After a while it began to make her wet, then the intensity increased. She moaned through the pacifier and squirmed but it only made it worse. Worse still she had to piss really badly. Half an hour later she mphhddd in orgasm and lost control of her bowels and wet herself. Every hour or so she would orgasm and all her restraint would go. By the end of the first day she was bogged down in wee and she hated it.. I enjoyed that for about two minutes, then I paused the movie and said, “Why don’t you go slip into something really sexy, and let’s have some fun.” She is always willing to dress up in some sexy stockings, heels, lingerie… she knows I love it. But before she left the room, she said something that really changed the entire night. She leaned over and whispered into my ear, “Think of something crazy –something new – something insane that will drive me beyond my limits tonight. I wanna go wild.
