My wife and I are a family of three living with my wife's mother, Sumire, Sumire. We decided to renovate our room, but due to the work, we ended up sleeping in the same room for about a week. On the first day, I was nervous and couldn't fall asleep, so I couldn't take my eyes off my mother-in-law's body, which I could see through my wife. I thought about sneaking up to her and grabbing her breasts, but I stopped myself. On the second day, my mother-in-law's breasts were still swaying through my wife. My wife was sleeping soundly, and I couldn't resist and went next to my mother-in-law. I was enjoying her soft breasts, but I was curious about her crotch, so I quietly slipped my fingers in. I couldn't contain my excitement at the nectar that was slowly overflowing, so I quickly left the place and ran to the bathroom to stroke my dick. The next morning, my mother-in-law whispered to me, who was sleep-deprived, that she wasn't angry about yesterday. Then, at night, I was woken up by a pleasant stimulation as I was sleeping quietly. When I looked, my mother-in-law was burying her face in my crotch and sucking me. I was in a panic, but she said, "You did that to me yesterday, didn't you?" and took my semen in her mouth and drank it all...
