Summer vacation! After school, sweaty female student Reo goes to the house of her neighbor, Umeda-sensei, to take a shower. When the teacher sees her wet, plump, busty body, Reo exclaims, "Huh? It's erect!" and presses her wet body against him, exposing his erect cock, and chomps it down with her mouth-pussy, full of sucking pleasure! Reo doesn't care about the teacher's resistance, as she sucks and slurps on his cock. The summer vacation begins with the lewd acts of a super-voluptuous, busty J-girl!
