Her back and butt were sweaty as they pressed against the hard mattress of the dojo floor. Legs wrapped tight around his waist she pulled him inside.
The other students had long since given up on telling them to go somewhere private. Or perhaps she was just no longer listening, stuck inside a warm libido bubble where only she and he existed.
Fingers nested in his sweaty hair, she closed her eyes and pulled his mouth tight against hers, tasting his tongue. Muffling the noise he made as she felt his warm cum inside her.
She did not usually find grappling to be sexual, but with him it had been inevitable. She also hadn't meant to fuck him in front of the other students, but that too had been inevitable.
They had been sparring, him on top frantically trying to find purchase for a hold, her struggling to move out from under his weight. Outside of practice he was cute in an everyday kind of way. Reserved, unassuming, prone to averting his eyes in a way that made you want to hug him. When sparring, with his game face on, something awoke in those green eyes and he looked irresistibly sexy.
Instead of any of the techniques she had worked into her muscle memory, she had followed a different instinct -- putting him in a somewhat unconventional hold by grabbing his neck and pulling his lips towards her own.
For a moment, his face had lingered inches above her own. His eyes wide in confusion. His warm breath on her face. That smell of sweat and spices, so unmistakably his, filling her nostrils. The moment extended in time.
Then everything had happened so quickly. His face splitting into a grin, he had eagerly gone the last few inches to meet her. She had tasted his tongue as they both breathed hard, scrambling to undo the knots on the other's pants, reaching inside. His shudder as her hand awkwardly closed around his erection, pre-cum already wet against her palm, almost perfectly matching the warm tingle of his fingers rubbing inside her.
At first she had been aware of the sounds of the other students alerting one another to the events unfolding, her arousal heightened by an ecstatic sense of panic. Then the outside world had faded from existence and her recollection of anything that happened from that point on was quite hazy.
