Kinky boxing! Rias vs Mai!!

Rias cried out loud as Mai continued to fuck her in the ass. Eventually she gave up and just allowed Mai to fuck her until she couldn't take it anymore and orgasm. The girl knew how embarassing it was, but she rather not waste energy in a fight she was likely going to lose and instead save it for one she could win.

Mai felt Rias' resistance die down, as she began to increase the pace of the ass-fucking. "Come on, honey let it all out!" Mai continued to Rias as the ass-fucking continued.

"Oh come on! Ref!" Rias cried out for some assistance. The poor girl didn't want to admit that she wasn't able to break free. The ref girl quickly came between them to remind Mai the goal was to fuck three different areas. Anymore attacking on her ass wouldn't count.
Rias was certain that Mai would back down or risk disqualification.
(Sorry, exam period, no time lately.)

Mai would stop fucking Rias' ass because of the ref's intervention. However, Mai noticed that Rias was too exhausted to stop her from fucking another hole. Mai then said "I'm not done with you yet."Mai would then flip Rias over on her back and held her legs up as she began to fuck Rias' pussy.

However that moment of brief respite was all it took for Rias to get back in the game.
As Mai tried to grab onto her legs, she would quickly swing her legs so that it kicked Mai in the side of her head knocking her down.
Naturally such an act would get her a warning, but it was worth it if she could do so, so that she could get enough strength to climb back on her feet.

Mai didn't expect the Rias to recover so quickly, nor did she expect to get kicked in a boxing match. The kick knocked Mai onto the mat but Mai would try to get back up to her feet quickly so she can get back into the match.

Rias took some time to catch her breath. Though she was hurt, she was still raring to go. As soon as the bell rang, Rias would circle around Mai, but not doing anything as she was trying to goad her into attacking.
She waited until Mai would either taunt her, or she attacked her.
If Mai taunted her, she would interrupt her with a straight to her face. If Mai tried to punch her, she would dance to the side and evade it.

Once Mai got to her feet she started complaining to the referee for not doing anything about Rias' blatant kick. "What the hell ref! She just kicked me!" Mai was angry but she wasn't paying attention to Rias who was waiting to strike.

The referee was responding with how she had given Rias a warning.

It was at that moment when neither was paying attention did Rias strike. She threw a straight right into Mai's face. If that connected, she would quickly step in and give her an uppercut to her stomach.

Mai was hit with a straight punch to the nose. Mai groaned and took a step back trying to cover her face not knowing what Rias was going to do next.
