This film, "My Sister-in-Law ~My Closest Desire~ At Home... My Beautiful Wife Wet from a Sexual Encounter!!", is essentially a story of incest within a family. In the film, due to the death of his mother-in-law, the male protagonist and his wife return to their hometown for the funeral. There, they encounter his wife's younger sister, "Miyuki Arisaka," who had returned home earlier. Because her husband had other commitments, she had gone back to her hometown alone.
So, since it was her hometown and she was in front of her family, Arisaka Miyuki was quite relaxed in her daily life. Her underwear was faintly visible under her skirt, or her nipples were clearly visible after a shower without a bra, all of which the male protagonist noticed. Compared to his aging wife, his young sister made him incredibly aroused and unable to resist…
Thus, unable to contain his lust, he broke into his sister's room late at night and raped her while she was half-asleep. Of course, his ignited desire was "uncontrollable"!

After successfully having his way with her, the emboldened male protagonist took things a step further. During the day, while Arisaka Miyuki was hanging clothes to dry, he couldn't resist groping her. She seemed to be still aroused by the previous nighttime attack, even rubbing her genitals against the bathtub while showering, sending the peeping protagonist into a frenzy. He pounced on her, ejaculating repeatedly!
Even when the husband returned, it was too late. Behind the happy family photos, the two were secretly having an affair. They started an illicit relationship in their hometown, having sex from morning till night. Arisaka Miyuki became addicted to the pleasure her brother-in-law gave her, becoming increasingly proactive in both oral sex and riding positions. It's quite a rare case of two couples being cheated on together!
It just goes to show, it's always hardest to guard against your own people…?
I'm really looking forward to Arisaka Miyuki's performance in the 2018/01/25 release 【家内の妹 ～ひとつ屋根の下にある身近な欲～ 実家で… サイレント性交に濡れる美顔妻！ ！ 有坂密雪】JUY-738.
