Creampie prank involving step-brother gets ex jealous

This story begins when my stepsister invites some guys over for an evening out after work. One guy decides that instead of just having sex as everyone expected they would — because apparently I’m too much trouble–they’ll use one last trick up their sleeve before leaving me alone with them again tomorrow night. And what’s worse than trying new things? Trying new things together.with multiple people present while we’re all standing right there watching eachother get fucked by those strangers. Well guess who was feeling really lonely lately without being able to invite anyone home since he had already sworn off dating her due to his own family issues which were getting pretty bad around him?
