Gia and Penelope are two school friends who come from very conservative and religious households. One day, Penelope shares with her bestie that she saw her step-parents having anal sex and just can’t stop thinking about it. This also sparks Gia’s curiosity, so the two try using a sex toy to explore their assholes together. Unfortunately, Dorian and Ken, their stepdads, are in the next room and come see what’s going on after hearing loud noises. Shocked to discover that their stepdaughters are doing this, the step-fathers use this situation as an opportunity to teach them how to take anal sex seriously…by swapping stepdaughters and teaching them how to do it.
