[Reducing Mosaic]DASD-451 Encountered in the bedroom at home. My boyfriend and a woman I don't know. Miho Yui

My boyfriend has been acting strange lately. When I come home, the bed sheets are new. After setting up a hidden camera in the room, I see...a woman with better style and who seems to enjoy sex more than me on my bed, begging for it. He said he couldn't get hard anymore, but he's getting hard right after coming. One day when I come home, I hear a woman moaning. When I open the door, there's an unknown woman sweating and thrusting her hips. 'Who is this woman!' She notices me and starts moving her hips even more intensely. (There's no crime in being sexy)
