I always had access to the studio. How was I supposed to know? No matter how much I tried to justify my actions I could not get over the feeling that ...I had violated my mother’s privacy again.The fact that my mother was on her knees sucking and fondling Derrick’s cock certainly surprised me. But it did not offend me. I finally realized what was bothering me so much. I had ruined her moment to live her fantasy. I could not blame her for being furious with me. And Derrick may never model for her. I saw Lauren’s calf muscles tense again and a moment later the pain cascaded around my bottom as the hairbrush landed. It hurt so much, as did the next spank and the next and the next. I couldn’t stop myself saying how sorry I was and was begging her to stop, but also willing her to continue, as I felt so aroused.

Her low, throaty moan was his undoing. ‘We can go slow next time, I promise.’ He said, giving no other preamble as he slammed his full length inside her hot core. She was tight, matched with the way she was clenching down on his aching cock he wasn’t. I rotated my head around his stiff shaft keeping his penile head in the grips of my lips. Bruce kept me at this for nearly twenty minutes and just when I thought he would come in my mouth he pushed me off. I looked at Bruce, not saying a word as he instructed me '...get us something to lubricate that tight ass hole of yours. If you can't find no hair grease get some cooking oil out of the kitchen...' I came back with a small glass of cooking oil, Bruce smiled and ordered me to '...make my dick.
