SODstars Suzu Honjo and Rei Kamiki appear together for the first time. At an adult swim-school role-play, coaches Suzu and Rei are famous for being exceptionally beautiful. Miyamoto, an adult student who constantly fantasizes about the pair, notices a paper charm stuck to a locker one day. It promises that removing it will make both women obey him. Miyamoto peels it off and turns the two coaches into submissive sex servants who follow his every command.
