A mistress

Moxxie waits in a cell nervous, he looks at his locked up dick at tries to see if he can possibly get it off but nothing seems to work the only way is to get a key.

He hears footsteps of heels coming closer and closer. The cell door swings open with someone wearing a black tight leather leotard that has its chest cut off so it exposes their boobs they also wear high heels.

(It can be someone from helluva boss or hazbin hotel or even someone from an entire other universe or even an OC)
