To avoid repeating a year, a busty female teacher provides all-night intensive tutoring. In this dream lesson, ejaculating improves grades; answer correctly for reward sex, answer wrongly for small demon torture, and it's an all-nighter with 14 explosions! Even if you climax multiple times, the intense sperm extraction doesn't stop until your balls are empty. The beastly teacher's abnormal sexual desire won't stop internal ejaculating until semen flows backward.
