Joushima was so upset when he found out the girl he had a crush on, Reika Shichijou, dropped out of school to become a cum dumpster, he didn't even fuck the girl assigned as his personal sex servant, Seika Watarai. But the next day he's annoyed to find Seika was reassigned to the boys' bathroom to be a hole for anyone to use! Joushima finally pounds Seika's pussy like she wants and fills her with cum... and then turns to see Ryouta Niimi walking Shichijou-sempai into the bathroom on a leash. Niimi wants to continue Reika's training, and he fucks her ass and hands out vibrators for the other guys to use on her pussy. It's going to be another educational day as these girls learn what it really means to be a cum dumpster!
