Sylvia began to unbutton her blouse making my dick grow even bigger, I heard a huge tear as my trousers split from the size of my dick. Her left hand ...an slowly up my body unhooking my black bra through my white blouse. She put her hand on my rock hard dick and began to rub it up and down. Sylvia ripped my trousers then looked up at my shocked face and grinned.I didn't know what to think. It was my dream come true being in a elevator with my sexy boss in a sexy situation. All of a sudden, the. ..Before taking off my chastity device she made sure i was properly tied down. She had me lie on my back and tied my hands away from my body on the floor. Then she spread my legs and pulled up my ankles all the way back until my knees were on the ground on the side of my head.After that, she kneeled on me, facing my cock, so that her crotch would be on my face.

Mum positioned herself on her hands and knees with her chest above my face so that she was looking right down at me. Her dangling, tits hung right above my eyes."Ready?" She asked.I knodded. "It was an argument that I was never going to win, I love being at her mercy, being helpless and used for her pleasure.My hole was puckering, in anticipation, but that soon disappeared as I felt her strong hand connect with my left cheek then the right, I knew that on any other time I would have to thank her for every stroke, and count each one, but as my mouth was full, all I could do was mumble, and moan, I could feel the heat rising on the surface of my arse.And of course this only increased.
