Brad started disrobing without going behind the screen.I watched fascinated as he removed is garments on by one. In minutes he was pulling off his bri...fs.Surprisingly his cock was semi-erect."Oh I'm sorry." He said embarrassed when he noticed his arousal. "It's O.K. I've seen hard ones before," I assured him.I still don't know why I did it but I walked over and took his cock in my hand.Brad's cock felt good in my hand, its girth and weight. I could feel it getting harder, "Mrs. Greene?" Brad. "I'm sorry I can't fit it very far down sweetie. It's just too big for me to do that." I told him.
