He proposes a deal.

"You two are lovers, am I right?" the man asked Sally, glancing speculatively between her and Jenna.

"Yes... that is... we've.... yes..." Sally stammered.

"Okay, I can see you care about her, and I'm not a cruel guy, so here's what I'll do. You go back to your friend and start eating her pussy and I'll come fuck you doggy style while you're doing it. Deal?"

Sally looked at him with alarm, her eyes wide and surprised. She looked from the man's calm but determined face to Jenna, who was too far away to overhear but obviously knew something was going on.

"Look, sweetie," he said, as if making a final offer, "either take the deal or I'll just walk over there and take her whether she likes it or not. The choice is up to you."

Sally bit her lip, frantic with indecision.
