MDB-713 I joined a harem sports gym and the naughty instructor committed to his instincts!! Yui Hatano, Hibiki Otsuki, Anzu Hoshi, Shuri Atomi

A man with a sloppy body joins a sports gym called Zenzap after seeing an advertisement. The gym operates under the motto of "committing to instinct." The man joined to reshape his body, but he finds only wonderful female trainers. It's a wonderful gym that stimulates his instincts and leaves him exhausted in a different way, as well as providing exercise. All the female trainers engage in harem play that will have him milking all his semen!!
