Sex Kakumei Okoshimasen ka? Nazo no Dokushin Kizoku ni Kareshi Sengen Saremashita

Jun Onodera was dumped by her boyfriend because of her insensitivity to sex. Just as she was starting to lose confidence in herself as a woman, she started dating Kengo Hidaka, a mysterious but handsome bachelor. Hidaka remained aloof and unreadable as he toyed with her, and before she knew it, he was trying to have sex with her for the first time!? Jun wanted to refuse, trying to hide the fact that she had trouble getting wet. But as soon as Hidaka touched her, her whole body felt weak and tingly!

"If I don't stop him… he'll find out I'm a frigid woman!"
"You've already made a wet spot down there."
What in the world is that squishy sound…? What… no way… is that coming from my vagina! Could he be...? The man with the "Magical Hand"! Can Hidaka start a "sexual revolution" in Jun's life?
