A teacher summons a student with large breasts to a hotel and indulges in them. He gropes her relentlessly, humiliates her, performs deep throat fellatio, and then enjoys endless paizuri. She washes her body with bubbles in see-through swimwear, uses her large breasts for bubble paizuri, and is rewarded with semen ejaculation. He makes her change into a gym uniform and plays with other teachers' large breasts. These beastly sexual predators pour lube and grope her mercilessly, use electric massagers and vibrators to make her squirt and orgasm, and cover her large breasts in semen through continuous fellatio. Further assaults make her scream in orgasm, and the evil teacher's intensive extracurricular lesson soaked in thick semen begins.
