Due to my wife's wishes, we are a couple who decided to live together at my wife's parents' house.There were no particular problems with living together, and I got along well with my kind parents-in-law.My mother-in-law, who is good at cooking, is a plump beauty, and because of her big breasts, I often had trouble finding a place to focus my eyes.However, my husband and I had stopped working at night since we lived together, and I spent every day in agony.One day, I tried to invite her to hold my wife, but she refused as usual.However, I could not suppress the sexual desire that had accumulated in the pool, and I was indulged in masturbation involuntarily with my mother-in-law's underwear.Then, her mother-in-law saw the bad things between her and tried to run away, but she stopped me to wait.Her mother-in-law is piling up because of her daughter, I'm sorry.She left me with a smile, saying that it was a secret between the two of us, who immediately fired me because it was so pleasant.
