The yankii younger sister of the wife always picks fights. She corners her brother-in-law. "Sis just stepped out, all alone?" she approaches her sister's husband in her underwear, trying to seduce him. Even if you think it's wrong, you can't help but get an erection. The yankii doesn't miss this and steps on his bulge through his pants... unintentionally feeling pleasure!! She's a bit scary when she glares, but she's actually kind... above all, she has a ridiculously sexy body... Near-incest sex while the wife is away!!
