Your bitchy step-sister catches you perving on her again and decides to punish you by giving you an ass job and then making you clean up the cum. If you want to be her cuck you also have to break up with your stupid little girlfriend. She can tell you are enjoying being a sick fuck so she invites her hot hung boyfriend over later to have some more fun. Watching them fuck and cleaning both of their asses then jerking off in the corner like a big fucking loser while waiting for another load to swallow.
