[Odenden (Etori)] Natsuyasumi mo Sensei Iinari! [Mr_Person]

Niiyama-kun's summer vacation gets hijacked when his teacher summons him, tosses him a swimsuit swiped from the school storeroom, and orders him into an inflatable pool for some so-called punishment. Lotion-slick hands wander where they shouldn't, and the sharp-toothed tomgirl's protests melt into shameless moans as his ass is teased open in increasingly humiliating poses. By the time his sensei is drilling him deep enough to wring out a hands-free climax, Niiyama is sobbing his apologies and clearly hooked on every punishing thrust.
