Main super mutant heroine, Shouko, is married to a normal human actor whom she needs to be very careful with when having sex with, as she has actually injured him, badly, during her uncontrollable orgasm spasms. Last time got so bad her husband is actually afraid of having sex now. That's where the actual male lead of this works comes in, he is a mutant as well who loves them sexy heroines, he is super flexible, almost rubber like, so he can't get injured easily; when Shouko witnesses a movie scene shot where her husband flat out portrays a man who's afraid of physical contact with his super wife and wants a human woman to love instead, in his thoughts however he's is actually sorry, and feels that Shouko would be hurt if she watches this scene, so in reality he is not that offput by Shouko like the character he is portraying, but unknowing to him she was there watching it live and Shouko takes that scene to heart, it gives her the push to pursue an affair with the rubber MC, who will have similar encounters with several other mutant heroines.
