Riko Tachibana, a sultry Japanese educator, can't resist the temptation of her young, horny student. Catching him stroking his hard cock under the desk, she decides to give him an unconventional lesson in oral pleasure. Kneeling before him, she guides his thickness into her mouth, her full lips wrapping tightly around his shaft as she bobs her head, taking him deep. The sound of wet, sloppy sucking fills the room as Riko's tongue swirls and flicks, bringing her student to the brink of ecstasy.
