Kat and Karina had spanked Amaya and Riley when they first arrived to the sorority house because Kat said it was authorized by the sorority leaders. Only it wasn't. So now it is time for some payback. Riley and Amaya put each girl over the knee for a sound spanking, then take turns on the other girl. They spank with hand, and with hairbrush until Kat and Karina are left with red, sore bottoms from Spanking Sorority Girls.
