Kinky boxing! Rias vs Mai!!

Rias getting dizzy from Mai's attacks was unable to do anything as she was shoved onto the ropes, where she stood helpless against her.

"I hope you like the taste of leather, honey." Mai taunted as she attempted to hit a left uppercut to Rias' jaw.

Rias sees this attack coming. However there isn't much she can do other than quickly place her gloves in front of her to block the attack. However because it was a hasty one, it didn't work properly and her own gloves slammed into her face, causing her to let out a yelp as her head snapped back.
Quickly she put up her guard again knowing that all she could do at this moment was endure Mai's attacks until she could fight back.

After Rias blocked Mai's uppercut, Mai wanted to try to keep up the pressure. Mai tried to hit Rias with a right hook to the stomach.

Rias worrying too much about her face, left her stomach exposed and Mai took advantage of it. She slammed a right hook into it.
"Ugh..." Rias cried out in pain as she closed one eye, as her knees wavered from the impact. At present, her stance was rather shaky.

Mai smirked a bit after she connected with her right hook. Mai then attempted to hit Rias with a left uppercut to the stomach.

Rias couldn't defend in time and so she took the uppercut to her stomach. "Kaahh!!" Her eyes widen as the blow slammed into her. The impact nearly forced her to spit out her mouth piece. In desperation, she quickly tried to cinch with Mai again, so as to stop the attacks.

Rias went for the clinch, but Mai didn't seem to mind. She believed she was in control, and thought that Rias was too tired to stop her. While in the clinch Mai attempted to lift Rias' legs in the air so she could insert her purple strap-on into Rias' pussy.

As Mai went and lift up her legs, Rias quickly knew what she was doing. Though despite this, she wasn't able to react in time to stop it, and Mai slid her strap-on into her pussy. Letting out a gasp, Rias quickly changed tactics in an act of desperation. She broke off the cinch, and quickly slammed a punch straight into Mai's kidney with all her remaining strength.

Mai believed she had Rias right where she wanted her, but then Mai got hit in the kidneys. This punch left Mai winded and caused her to release Rias from her hold. Mai is now holding the area she was punched as she also dropped Rias after the punch.
