Busty G-cup beauty Ibuki Kanon is caught carelessly mixing her trash: used condoms belong with burnables, while vibrators do not. Her revealing breasts and poor sorting habits inspire a very physical lesson. The instructor enters while she is masturbating, jokes that her bra belongs in recycling, and gropes her huge tits before licking her bare pussy until it is dripping. Kanon relaxes into the pleasure, and the pair become hooked on turning their trash-sorting lessons into creampie sex.
