The righteous magical girl [Hearty Cherry/Ousaka Chieri] was driven to despair by the hands of [Soil], an officer of the evil organization [Plague Guard], and swallowed by the evil mud.
She was reborn in the form of [Muddy Cherry], a servant bound to Soil... At least, that's what should've happened.

But Soil has grown increasingly annoyed with Muddy Cherry, who refuses to listen to any of his orders and treats him like her lackey. And so, he tries to take control of Muddy's reins by using his signature massage to challenge her to an orgasm contest and see who can make the other climax. However, Muddy arbitrarily changes the rules to make it a “mutual orgasm contest,” and after using a urethral bougie to stop Soil from ejaculating, she uses her entire oil-slick body to give his cock continuous pleasure...
Will Soil be able to defeat Muddy Cherry?! (He won't)

He is an officer of the evil organization [Plague Guard], who seeks to fill the world with despair.

Unable to control his servant, [Muddy], he ended up being dominated by her.

In an attempt to get a grip on Muddy, he sets up a massage game "you lose if you cum," but instead, she denies his orgasms and torments his entire body with her voluptuous body...
