step-Sister Dahlia and step-Sister Katana have been secretly pleasuring each other behind Superior Bats' back. After Bats catches the two nuns, she tells them that they will have to be disciplined. Katana and Dahlia ask the head nun if she's ever experienced pleasure before. They convince Bats that it feels good to give into sin. The nun gets groped as she learns to suck cock and repeat mantras. After cumming, Superior Bats accepts that she is now their step-sonal plaything.
