"What is he going to do?" Ichiro muttered in the bath.A night when my wife is away on a trip.Her sister-in-law Yumi came over.She couldn't grasp her intentions, but she was puzzled by the sudden visit... "Would you like me to wash your back?" Naked Yumi came in there.She seemed to think that Yumi was trying to seduce Ichiro and use it as an outlet for her sexual desire.She cannot betray her wife.Moreover, her opponent is her sister-in-law.Ichiro desperately tries to use her reason and refuse, but Yumi has her bewitching smile on her face and keeps her body in close contact.
