I didn’t know how long he had taken, but Tim stood up and put his hands on his head and stared at the wall above my head.Almost disbelieving he was submitting, I stood up and went and stood behind him. I leant forward and spoke softly into his ear, “I want you to remove your shorts and pants and go and bend over the right arm. Maybe as thick as Brad's cock. He slowly worked the vibrator into me, slowing down when I told him the thick base hurt.

He had to have his significant other’s permission to participate. The ad went on to say that the volunteers would receive $100.
