[477GRMO-108] Ningen observation Seduced by a sister-in-law who quarreled with a sexless boyfriend and ran away from home, and had unfaithful SEX without his wife

My sister-in-law quarreled with her boyfriend and ran away from home, but the wife did not return overtime and was a serious brother-in-law who responded alone. The cause of the fight seems to be sexless, and she is seduced by her sister-in-law with a momentum that makes her feel unattractive. Even though I knew I shouldn't, I couldn't control my excitement at being younger than my wife and having a nasty body, and I drowned in my sister-in-law's.
