SDMU-479 - Best friend and boyfriend cheating in front of me? Revenge sex between the betrayed

It's a self-swapping style story where partners cheat on each other during a double date. The plot of confirming the affair through a magic mirror and then having sex as a form of revenge was good. However, even considering the story, the pacing felt a bit lacking. It would have been better if the revenge had been a bit more intense rather than just standard. Also, it feels like this premise could have worked even without the magic mirror.

I bought this for Yuri Oshikawa, but I didn't find anything particularly good about it overall. Even the scenes with Yuri, which are the main point, had poor camera angles, so it wasn't very practical. It's going straight to the resale pile.

Three couples appear, and their reactions are all different. The first, Yumi, makes a quick decision the moment she sees the condom; after fully enjoying the sex, she leaves, saying she doesn't even want to see her cheating boyfriend's face. The second, Kaori, is petite with small, pink breasts and a childlike figure. She moans intensely while being taken from behind, all while listening to her boyfriend outside, who is in the middle of a passionate kiss with his affair partner. They came out as a group of four to talk after, but who knows what will happen. The third, Aya, is a beauty with a stunning figure—she looks like the actress Matsuyuki, or maybe not? The 'absolute territory' between her miniskirt and thigh-highs is so erotic; she's my favorite. After putting the condom on the man, she asks to hear the voices outside one more time; the moment she hears them, she makes a sad expression before allowing penetration—it was a tear-jerker. Even after it was over, she said, 'I love Ma-kun so much, so I won't say anything about what I saw or what we did. I'll work hard so I don't lose to her'... what a sweet girl!

Does anyone know the name of the last actress? Please let me know if you do.
