Smothered All Night

I'm alone in a room and sitting naked on a chair with my arms tied up. A gorgeous woman comes into the room and puts her hand over my mouth and tells me to be quiet. She leaves the same hand on my mouth and with her other hand she starts to stroke my cock slowly. This goes on four hours where she tells me how I can't speak whilst she caresses my balls and plays with my hard cock. After such a long time my covered mouth starts to make moaning noises. I have the best orgasm I've ever had and I cum all over her.
