In the back of the old school building, there's an unused gymnasium. Inside a locker there, a mysterious flyer. Hesitantly calling the number written on it... what, what! Students and female teachers had opened a rejuvenation massage parlor to earn pocket money!? That girl from the next class... my big-breasted junior... even my admired teacher... even the top student of the year... everyone has wandered into a dreamlike space where they are refreshed in body and mind, even their balls, with close, slippery oil massages in erotic costumes and even more erotic secret options!!
