The boys, desperate to have sex with Eimi-sensei somehow, trick her into drinking a Ramune candy laced with an aphrodisiac to see what happens. The teacher is in a sexy mood! But, what? It's too effective... She can't stop riding him at high speed and destroys the condom! Furthermore, she feels so good raw that she can't stop thrusting and cums inside! The teacher's lewd slut transformation goes out of control!
