As I knelt on the bed and watched my own son wrestle with the door of this strange room I realised I had been totally out of control.

I drew the sheet up to cover myself and moved to sit on the edge of the narrow bed. Brad was still magnificently erect and, in his desire to escape, made no attempt to cover himself.

His huge cock bounced and waggled as he banged and pulled uselessly at the door. I felt desire for him flood me once more.

"Bradley." I said sofly, using a form of his name we only used to repremand him. "Stop it. It's useless. Something some one has locked us in here. Let's just try to stay calm and think."

He stopped struggling but didn't turn to look at me, remaining at the door with his broad back to me. His head was down and I wondered, for a moment, if he was weeping.
