MRSS-120 My wife, drunk and returning home, mistakenly entered the neighbor's junk house. She mistook me for her husband and got aroused by a middle-aged man, leading to unprotected sex. This is Hibiki Otsuki's story.

My wife and I, Hibiki, are a newlywed lovebird couple. Today, Hibiki went to her company's drinking party but hasn't come back yet. However, since everyone at Hibiki's workplace is female, nothing weird should be happening. She's probably just taking her time with the drinks. Anyway, moans have been leaking from the next room for a while now. It's incredibly erotic. It kind of sounds like Hibiki's voice. We promised to have sex when she gets back, so I need to hold back, but I can't take it anymore—I'm going to jerk off!
