I would have screamed, but Tom had put his hand over my mouth and told me to relax and ride out the pain, and before long Frank was filling me with hi... cock, all the way to his balls has they slapped against my thighs. I was dimly aware of Tom getting to his feet, and some voices in the background, as Frank pummelled my arse, and grunted he was cumming, and I had my second load of cum deposited within my body.

"But Ma made me come, so here I am."Dr Knox nodded. "Sarah Lee, your mother is a wise woman. Before you leave here today you'll understand exactly why this is necessary. First, take off.
