[Kokusan JK (Velzhe)] Buttfuck Practice [WannaSS]

Coach's orders: anal drills. In a school gym where every mat hosts a panting pair, a bald old instructor in a tracksuit walks his students through preparation—rimming eager young rims, then stretching them with thick lotioned fingers—before demonstrating on petite Sawato exactly how a big, girthy cock reshapes a twitching little hole, working her sweat-slick body through shaking orgasm as an awestruck classmate looks on. When her young admirer finally earns his turn atop her, lips crashing together mid-thrust, the possessive teacher shoves him aside to correct the boy's hip technique firsthand. Even after bloomers get peeled aside for a heavy x-ray creampie finish, practice isn't over until everyone's learned their lesson.
