It was his birthday, so she invited her little sister and her best friend over to work his cock with her. She made sure to spend hours licking his asshole, while her little sister and best-friend switched back and forth between his balls, or spent time bent over with his cock pounding at their hot, slutty, little holes. He told them this would be a weekly thing from now on, and they agreed it was for the best. After all, they all needed a weekly dose of cock, and he had enough to share.
