妻と倦怠期中の僕は逢花（義妹）に誘惑されて何度も、何度も、中出しをしてしまった…。 (2019)

Overview

My wife has gone on a trip alone. As the couple's relationship cools down, he can no longer stand the temptation of his wife's sister, Aika. Still, the more she thinks it's useless, the more her reason is blown away... During the day, night, and morning, while her wife was away, she repeatedly had intense sex with Aika, and she made vaginal cum shot over and over again.
