Usagi-chan, Doshikori Moushiagemasu

Trying to relax, Mitsuomi goes to a man-boob pub, where he meets Megu-kun—who has big pecs, a big ass, and an erotic body—and falls in love at first sight. If you rub his inverted nipples, Megu-kun gets hard!? Going all the way isn't allowed, but a little comfort is fine... right? A fluffy and sexy story begins!
