[Saboten Binta (Kawakami Kou)] Showdown! for the Assvisor Sensei [Black Grimoires]

Two busty schoolgirls corner their teacher after discovering his two-timing between the swimming club and the cosplay club, and demand a shameless showdown to settle which of them deserves him. What starts as a scolding quickly becomes a double paizuri contest, with the pair pressing their huge breasts together around him until he erupts across both their faces. The lesson continues in the shower, where he takes turns plowing each girl from behind, deciding that if he can't choose, he'll just have to scrub both pussies clean with his cock.
