Newlywed life at my wife's parents' house. My mother-in-law is also kind and loves my wife. My sister-in-law came back to this peaceful house and my daily life was broken. A sister-in-law who seduces me as a matter of course. I managed to escape, but for a moment, I couldn't join a man I didn't know in front of me ... I was finally eaten by my sister-in-law who was too free-spirited, and I was addicted to the swamp of unfaithful sexual intercourse with my sister-in-law.
