KAWD-602 - I couldn't help it... having secret sex with my friend's girlfriend

*There's not a trace of reality in the setting, where he moves in with his best friend who lives with him (lol). Ever since her debut, Tsubasa Aizawa has been shying away from her because of her overly loud panting, but in her current work, her overly loud panting doesn't make you feel like you're peeking at her. I can't help but think that instead of trying to control the way she speaks, she's trying to make her listen. I don't think it's possible for her to create a drama. It was a mystery until the end as to what was "secretly" about.
