Satou's in a bind. He's desperately trying to keep studying while working to pay the bills, and this time around he just doen't have enough. He heads to college in a depressed slump, and with surprisingly good timing, his friends Kaname and Hata approach him about a part-time job. Satou jumps right in without so much as asking for details, and if it sounds too good to be true, it probably is... Surprise! Enemas. Edging. Anal stretching. Nipple tweaking. It goes on and on... He's a test subject for perverted acts! Just what is the point of this high-paying sexual experimentation job?!
