Marco started rubbing Francisco's cock. He put his hands around the extra large member and started stroking up and down. Francisco groaned in ecstasy but still thought that it was ridiculous to have such an enormous penis. Trying to remember what phrase to use to shrink his mammoth penis down to a more reasonable size, Francisco accidently said "Auctus Genitalis" again.

The growing suddenly stops but Mendes's huge 6 foot long and 3 foot wide penis is sticking straight up out his crotch while he's sitting on the couch. Marco's body is wrapped around it, stroking it with his entire body. Marco suddenly thinks of another secret fantasy he's dreamed about. While Francisco is moaning in ecstasy, Marco says "......
