Yuuma is an ordinary sub who's having trouble finding a partner. Ever since his friend Mao bit him in high school and awakened his sub nature, he's been seeking that feeling of pain and pleasure, but his partners just can't seem to give it to him. He's finally matched with Mao himself, and Yuuma is ecstatic at the prospect of feeling the way he did before, but Mao is determined not to hurt him! Mao decides to teach Yuuma what a dom/sub relationship should really look like, and while Yuuma finds it enjoyable, he starts to worry he'll get in too deep. Pretty good up to chapter 4, but the plot gets a little confused after that. Trigger warning: violence.
