Offering Up My Virgin BFF

A deal is a deal, but I'm beginning to regret the one I made with Mr. Thompson. After saving me from trouble, he took my virginity, but I wouldn't let him finish inside me. So I make a deal, putting my best friend Mary in a compromising position, then letting Mr. Thompson have his way with her. But when I see him fill her with his impregnating creampie, I'm torn. I've avoided it for weeks, but I might change the terms of the deal- even if it means that both Mary and I will get pregnant!
