a teacher summons a big-breasted student to a hotel and indulges in her massive tits. He fondles them relentlessly, humiliates her, makes her deepthroat, and enjoys endless paizuri. She wears a see-through swimsuit and washes his body with bubbles, using her giant tits for bubble paizuri. As a reward, he shoots his semen. He changes her into a gym uniform and has other teachers play with her huge tits. Beastly sex maniacs pour lube all over her and grope her mercilessly, using vibrators and dildos to make her squirt and cum. They finish her off with continuous blowjobs, covering her giant tits in semen. Finally, they fuck her senseless, making her cum with a twisted expression on her face, in this intense, semen-soaked extracurricular lesson.
