Netorareta Bakunyuu Tsuma-tachi Season 2 Ep 2

What was supposed to be one last time at a love hotel only pulls Megumi in deeper. No matter how many times she swears she's finished, she can't resist the well-endowed student next door, all while her husband stays buried in his work.

By the time he finally comes home and catches them in the act, Megumi has already been bred and claimed completely as another man's woman.
