"Extra training!" she yells, summoning students and forcing erotic private lessons on them for failing to swim. She ties their hands with ropes hanging from the ceiling, clamps their nipples, and whips them mercilessly. On rainy days, she screams "Extra training!" while injecting multiple enemas of milk into her students. She throws women into pools and dumps ice on their heads, a cruel teacher without mercy. She makes them swim while engaging in bareback sex in the pool—an extreme act of domination. Outdoors, she forces women into seiza position and piles stones on their thighs before subjecting them to candle wax torture. "You were smoking, weren't you!" she shouts, making students wear bloomers, injecting them with enemas, then forcing them to run. With hands bound behind their backs, she torments them ruthlessly with vibrators and glow sticks. She spreads their legs wide and binds them open, using a low-frequency massager to deliver electric shocks. Finally, she hangs them upside down from the ceiling for relentless flogging.
