Old dog and new tricks~ [LunarOcean and radiantkarna332]

Yahagi wasn't sure if she was climbing slowly to victory or busy enjoying defeat; both sensations blurred together in the coiled mess of lust and ecstasy that was both of their bodies pressed so tightly together. She grunted in annoyance as Eirina complained, her own trembling and needy abs tensed and grinding slow and hard over Eirina's tummy. She tried not to huff and pant; tensing at this level was taxing on her body and she felt she'd crumble any moment. Yet this increased abdominal hardness rewarded her with both additional sensitivity and power, letting her grind deep into the increasingly softer abs of Eirina and lighting both their bodies alight with fiery pleasure.

"Stop... complaining..." Yahagi's lips found Eirina's and pressed down hard, saliva mixing and tongues exploring, pushing her head down to the mat. Her movements would still but Eirina would feel a powerful, lust-driven pressure crushing into her tits and abs, making the latter buckle and parting the former like the Red Sea. Yet only Eirina would hear the loud moans spoken directly into her lips as Yahagi began to expend the last of her energy into dominating Eirina!

At this rate, Eirina would certainly succumb under the might of the younger woman, and she would have no choice but to be tamed by her sensual prowess. But, for a woman like Eirina, there were fights that she could not afford to lose, and this one was one of them. At the brink of defeat, Eirina would try to call forth whatever left of her strength, attempting to do one last ditch effort to turn the whole thing around. The untapped potential that Eirina did not unlock, she tried to make use of it.

And slowly, her mind turned blank. Not due to overwhelming pleasure or arousal overloading her brain, but due to her conscious effort to still her senses. Under normal circumstances, there's no way she could accomplish such a feat, but due to being driven by pure stubbornness and spite, Eirina stopped thinking and only acted on pure instinct. She had become nothing but a machine made of flesh, methodically enduring whatever Yahagi was throwing at her with the efficiency of a fleshy automaton. Her expression was that of serenity as she fought back Yahagi's kiss. She would also grind her body against Yahagi's, this time much rougher and more primal, totally driven to overwhelm Yahagi's senses with such erotic rubbing.

Like mentioned before, it was a last ditch effort from Eirina. While it might work for a short while, it wasn't something that Eirina could maintain for too long because she would soon come back to her senses, and that would bring instant defeat once that happened.
