妻と倦怠期中の僕はまりん（義妹）に誘惑されて何度も、何度も、中出しをしてしまった…。 ひなたまりん

My wife has gone on a trip alone. As the couple's relationship cools down, she can no longer stand the aggressive and challenging temptations of her wife's sister, Marin. Even if I thought it was no good, Marin, who has a better style than her wife, was too erotic... Day, night, morning, Marin asked me, and while her wife was away, I repeated dense SEX, I had vaginal cum shot over and over again...
