An ass kicking

Power Girl won nearly every fight she was in but that was due to her powers. She didn't have technique or skill while Onyx has had years of fighting experience. A lash of her whip connected with Power Girl's chest down the front of her body causing a long tear and a grunt of pain from the blonde heroine.

Power Girl felt fear. That hurt. She wasn't used to being hurt.

_"Okay Karen your powers may be gone but you're still Power Girl you can't give up" _The blonde heroine told herself just before another strike from the whip came this one directly on her left breast which sent her sprawling to the ground, landing on her sore breast.

"How does it feel Power Girl? To feel pain? To feel what the rest of us feel?" Onyx sarcastically asked as she struck again this time on Power Girl's ass, leaving a tear in her white costume and a red mark on her ass.

Power Girl ran a hand on her sore ass and tried to stand only for Onyx to kick Power Girl's ass literally sending her back to the ground. Pain ran through Karen's body as another strike came down across her back, tearing her costume further.

"Stand up" Onyx commanded

Power Girl stood to fight only to get a strike to her pussy. Instantly her hands went to her crotch. The constant tears finally took their toll and the blonde's costume fell apart leaving her in only her blue gloves and boots.

"My my I think they may be even bigger than they looked" Onyx commented

Humiliated and naked Power Girl lunged at Onyx. Onyx on her part used her whip again this time to wrap it around Power Girl's arm. Onyx pulled the kryptonian in who lost her footing and stumbled into Onyx who put both her hands on Power Girl's shoulders and brought her knee up as hard as she could to Power Girl's pussy.

The kryptonian screamed and grabbed her sore pussy as she fell to the ground. Onyx stomped on Power Girl's back forcing her massive breasts into the ground as the dominatrix repeatedly stomped and ground her heel into the heroine's back.

Onyx's whip was quite advanced able to change settings and forms. With the press of a button it transformed into a paddle that was brought down on Power Girl's ass making it shake as the kryptonian let out a yelp. Blow after blow came down on Power Girl's perfect ass Onyx taunting all the while

"Come on Power Girl just punch me into space, freeze me with your breath, reverse time and get the drop on me! Do it Bitch!" Onyx called out

"Stop it!" Power Girl could only cry out, having to accept she was powerless

"Beg me" Onyx commanded

"What?" Power Girl asked in shock

"Beg me to stop. Accept you are beneath me and I will allow you to spend the rest of your days as my personal bitch. If you don't we will cross that bridge when we get to it. Kiss my boot and beg me to stop" Onyx extended her other boot to Power Girl's face
