[EB110SS] Mr. Muscle Ch. 1-3 (Okosama Pyuppyu)

A hulking masked figure known as Mr. Muscle prowls an elementary school, roping a bound, gym-uniform-clad girl into a brutal lesson she won't forget while her classmates line up declaring they're next. Meanwhile a pack of shota students corner their soft, glasses-wearing teacher Ms. Tomoka, swarming her to finger her squishy pussy and beg her to cum for them all before the director catches on. The chaos barrels toward a schoolyard wrestling tournament where tiny Hideki dares to square off against the muscle-bound giant himself, closing on a crowd of cheering kids.
