With a Friend Like This...

"Aahh!" Sierra moaned as she felt Da Xia's tongue lapped her sex. "I-I'm going to win!" she said with a determined expression before start licking Da Xia's sex with a quick pace.

Despite what she said, Sierra was pretty distracted with Da Xia's licking too much to be able to launch her assault properly. She simply tried to drive her sparring partner to the edge with brute force, just lashing her tongue consistently hoping that she could overwhelm Da Xia with the pleasure. Her rhythm was disrupted occasionally whenever the girl hit her sweet spot, though, so she couldn't really stimulate her sparring partner as much as she wanted as it was.

"Mmmff... mmmmfff...!"

"Mmmm!!!" Da Xia moaned out as she felt the vigorous tongue of Sierra's lashing into her sex, but the difference between her and Da Xia was that Da Xia was able to keep up her assault despite having a hot tongue whip back and forward across her sensitive sex. However that didn't mean it had no effect on her, Da Xia's pants began to increase and breathe out hot breaths over Sierra's sex while more and more of her juices were leaking out of her. Although her trainee lacked technique and consistency, she had the motion down and Da Xia knew that if she let Sierra keep it up, she was finally going to lose to her.

"N-no you're not!" Da Xia shouted out as she increased her speed, lashing her tongue across of Sierra's sex, temporarily halting her plan to plunge her tongue into Sierra's hot sex. Licking Sierra's sex she soon saw Sierra's clit and an idea popped into Da Xia's head as she would attempt to latch her lips on the nub before sucking on it as hard as she could to try and over stimulate Sierra into submission.

"Nyyaaahhhh...!" Sierra moaned in high pitch as she felt Da Xia sucked on her clit, her body jerked under the girl in response.

She stopped her licking for a bit as the sensation was electrifying her body to the point it's almost paralyzing. By the time she was snapped out of it, Sierra would try to catch up by licking Da Xia's womanhood as much as she could again, but she could already feel her own arousal building up close to the limit...

"H-haaa...! Mmmhhaa...!!"

Da Xia felt Sierra licking after the burst of sensual pleasure of sucking on her clit. It was dirty tactic to get ahead of Sierra and Da Xia didn't care as she released the clit from her lips and began to lick Sierra's sex again. She could tell that Sierra was close to climaxing with the amount of her juices leaking out of her. "Mmmm! Mmmmm!!!" Da Xia moaned as she would try to snake her hands between Sierra's buttcheeks and the mat in order to grab a hold of them. There really wasn't a point to it, but Da Xia felt like giving a little butt massage as she got Sierra to climax again.

Her licks would fast and hard, pressing down on the wet sex as she tried to lick the entire length of Sierra's flower. Although Da Xia had a decent amount of arousal built up, she was quite confident that she could get Sierra to cum first before she even came close to orgasming.

Sierra tried to give it her all to make Da Xia cum first, but in the end, she's getting exhausted before that could happen, and while her licking was getting sloppy, her sparring partner's was more consistent. The inevitable would soon happen as the raven haired girl tensed and began to buck herself a few times.

"Aaahh...!! Ahhnn...!!!" Sierra moaned as she came again, her body writhed in pleasure, her tongue going slower and slower on Da Xia's sex as her strength was drained by the climax.

She limped under her sparring partner soon after her orgasm subsided, breathing heavily while staring almost blankly to the room's ceiling. That was so close, and she still lost, again.

Da Xia smiled as she felt Sierra beginning to buck as the signs of her climax had finally come. It was Da Xia's victory again as Sierra's sex sprayed out her juices, getting on to Da Xia's face before she opened her mouth to drink in all of the juices. It was for a split second, but after Sierra climaxed, Da Xia's body slumped into Sierra's before tensing up again. A sign to Sierra that it was definitely the closest bout the two had so far in their extended training bout.

After taking in the rest of Sierra's orgasm, Da Xia rolled off of her trainee as she was still hotly panting with a fresh coat of cum on her face and chest. "Close...but not good enough Sierra." she 'praised' Sierra as she sat next to her raven haired student as she continue to pant. Her sex was still leaking out her juices as she was still aroused after that hot sexual duel of theirs. "Now then...for my request..." she began as she lifted her arm up to show her sweaty arm pit, Da Xia got a devious smile on her face as she looked at Sierra. "I want you to lick my arm pit."

It seemed that Da Xia managed to reach her orgasm as well soon after Sierra did, but not that it mattered too much. She was still defeated in the end, and owed the girl another request as it was. While still recovering from her latest orgasm, the raven haired girl heard Da Xia's request, and her cheeks turned bright red almost instantly.

"Y-your armpit..." she repeated, already imagining just how sweaty it would be after their intense sparring session, not to mention the smell!

She had no choice but to do it, though. Sierra slowly sat up and crawled towards Da Xia, looking a little hesitant, but still willing to fulfill the request. Taking a deep breath of fresh air, she'd move her face close to the girl's armpit and began to lick it.

Eww... the raven haired girl closed her eyes and wrinkled her nose as she smell the scent of Da Xia's sweaty armpit.

"Yes...my armpit." Da Xia said as she watched as Sierra readied herself to do the deed as she moved into her arm pit. Da Xia let out a giggle as she felt the tongue that was just licking her crotch was now licking her arm pit. She didn't quite care how rather nasty the request was, it was what she wanted and as per their agreement she knew that Sierra couldn't complain about doing it.

Didn't mean that Da Xia couldn't complain about how was Sierra doing it.

"Hey, you're not licking fast enough!" she barked, once again forcing Sierra to work even harder for the request as she would use her other hand to push the back of Sierra's head into her armpit to force Sierra to do better. "What happened to that tongue that was lashing at my pussy? I want that tongue lashing at my pit!"

"Mmmnnghh!" Sierra was once again subjected to Da Xia's displeased act as the girl shoved her face to the her armpit, almost rubbing it all over her features.

It seemed that no matter what she did, she'd always found herself in this situation! Part of her kinda suspected that Da Xia was doing it on purpose, but the rest of her seemed to want this embarrassing act to be done as quick as possible. The scent and heat was making her a bit dizzy already, and she complied by licking Da Xia's armpit faster, hoping to satisfy the girl this time.

"Mmmmm!!" Da Xia moaned out when Sierra started to lick her armpit with more vigor. With her opponent's nose also rubbing into her pit made her a bit ticklish as well. After a few more licks, Da Xia was satisfied with her request as she released Sierra's head, "Phew...that's good enough." she said as she then realized she's been letting her facade slip and needed to rebound with it in order keep up appearances. "But....you're definitely getting better, you almost had me in that 69." she praised her trainee while she saw the condition she was in.

"Looks like you're almost done. Want to do one more round before calling it a day?"
