Blood Type B, Wet and Hot Sister in law [Uncut]

A hot sister-in-law who can’t live without men and the sex scandal involving two brothers. Who will she sleep with tonight?

One day, Min-soo’s younger brother Kyeong-soo tells him and his wife Yeong-hee that he’s going to sleep over at the couple’s house like usual. Later, while Yeong-hee is busy with a business trip and Min-soo is out for work, Kyeong-soo finds himself alone at their home when Young-hee’s younger sister, Ga-hee, unexpectedly shows up to visit the couple. Ga-hee suggests having a beer to break the awkward situation of being alone in the house. Ga-hee eventually gets drunk and ends up having sex with her older sister’s brother-in-law. However, the real reason she came over was to seduce her brother-in-law. Later that night, after sobering up, Ga-hee quietly heads to Min-soo’s room.

Will Min-soo be able to resist his sister-in-law’s temptation?
