Shion gets a call from his drunk girlfriend, Ito. When he arrives at her place, he finds a strap-on that looks newly bought. When he asks why she got it, she gives him a puzzled look and says, "To use it, of course. Why else?"
Shion wants to do whatever the woman he loves wants. She has already trained many parts of his body, but the only thing he has used before is a prostate massager.
Still, refusing her isn't an option. In the end, Shion climbs into bed, ready to be embraced by Ito...
"I wanna break up." Ito is dumped by the boyfriend she's been with since her school days. The reason? She "awakened" him so completely that he can't enjoy ordinary sex anymore. Now Ito herself can't get off from anything normal either. If she starts seeing someone new and ends up breaking them the same way... will she just get dumped again? While wrestling with that thought, she remembers a young man she once met online-someone who said he was "into that kind of thing." Thinking, "If it's just a bit of kinky fun..." she agrees to meet him. But after some intense, kinky sex that unleashes his desires, the roles suddenly reverse-and now she's the one being pushed past her limits, over and over again...!?
