Some light sparring (...and chill?)

"Ooooh, you might jinx yourself like that, 'Haku-chan~" Rui smiled as she approached Kohaku slowly, also raising her arms. "Heheh... I hope your boobs are ready!"

And with that, she lunged forward, looking to initiate the lock up.

Kohaku would simply smile at hearing Rui words. “You should focus more on the match than the prize.” stated Kohaku in response to Rui remark. As her opponent came charging in, Kohaku would quickly get down on the ground and try to place one leg in front of Rui while also attempting to put one behind her, trying to set up a drop toehold in order to send her opponent right down in the wrestling mat face first!

As they clashed once more, Rui pushed forward, trying to overpower Kohaku again. Unfortunately for her, the maid got the drop on her once again, hooking one of hr legs and dropping the busty girl forward, causing her to land quite unceremoniously on her tits.

"Owwwwwww...!" Rui groaned, trying to bear with the pain in her chest while she tried to push herself back up.

Kohaku little trick had worked and Rui smack the canvas face first.  “Poor Rui-chan but don't worry it will soon all be over.” stated Kohaku as she would try to grab her opponent's legs and sit on her back.  If everything went according to plan, the redhead maid would start to pull back Rui legs, applying a Boston crab in hopes of making her opponent tap out.  She wasn't sure if this move was legal or not, but it was worth a try.

"Ghhhhhh...!" Rui groaned loudly as Kohaku pulled her into a Boston Crab, slowly bending her spine. What was worse, is that some of the strain she suffered in her match a few days earlier began to stir up again, making the pain even worse than normal.

With little else she could do, the bluish-green haired desperately tried to claw her way to the nearby ropes, unsure of how long she could bear this hold.

“Ready to give up yet?  Oh, do you even get a rope break in this kind of match?” stated Kohaku as she would apply more pressure by pulling back.  She didn't really know the rules too well aside that no strikes were allowed and leaving the ring meant an automatic point.  There technically wasn't a referee to enforce the rules so Kohaku didn't have to worry about being disqualified so she could continue to apply pressure even after Rui got to the ropes.  Though Rui was a friend and she did want to be somewhat nice to her and not do something so mean to ruin their friendship.

"Ah crap...!" Rui cursed, not even totally sure how it worked in this situation either. Even holding onto the rope like this, she couldn't really do much more without straining her back further. With no other choice, needing this to stop before her pain got any worse, the busty girl tapped the mat in submission.

"Alright, alright you got me, 'Haku-chan, now let goooooooooo...!"

Kohaku smiled as Rui cursed, realizing her misfortune.  She would continue for a second or two more until Rui finally tap and admitted she lost.  “That means I win three to one.” stated Kohaku as she let go of Rui legs and got off her.  “I wonder what kind of punishment I should give you now.  Maybe I should grope you and give you a taste of your own medicine?  Or would you actually enjoy that?” stated Kohaku as she tried to think of different possible punishments.

Rui let out a gasp of relief as Kohaku finally freed her, rolling onto her side a nursing her aching back for a while. Perhaps she hadn't recovered quite as much as she thought....

"Oooh, I dunno, why don't you try so we can find out~?" Rui chuckled with a strained grin on her face, deciding to remain on the mat until the pain died down bit more.

Kohaku had already given Rui a spanking and groping her only seemed to turn Rui on, thus it wasn't really a punishment.  Well did she really need to punish Rui, maybe the punishment could be something that Rui did enjoy. “Alright, I think it's time for a grope.” stated Kohaku as she would groping motion.  She would now try to get behind Rui and places her hands under Rui clothing before going for a very personal grope, trying to even touch the nipple.
