Just before he was about to cum I backed off and told him to stay still.
Megan gave me a zip-lock bag.
"So, you've got a nice big dick," I said. "Do you have a lot of cum?"
He nodded and sweated.
"Have you been holding it in like I've been asking you?"
He nodded.
"Have you been a good boy?"
He whimpered.
"O.K. I'm going to let you jerk off then stroker boy. If you've got enough cum like you say you do, then maybe we'll let you off."
Within three strokes he came.
Amazingly, he stayed hard?!
