Interlude: Lucy waits for Billy to wake up.

Lucy sat near Billy and watched him. Her chest was still rising and falling quickly, her heart rate high from the thrill of the sparring match. Her legs were drawn up and she was hugging them, looking at Billy through the gap between her knees. If Billy had been awake, he could have ogled the backs of her thighs, which were completely exposed. He even would have been able to see a tiny bit of her panties that were visible due to her tiny shorts riding up.

But he wasn't awake. He was out cold. Dropped, slept, defeated by one vicious, downright sexy series of punches from Lucy.

Lucy looked at his body. Tall and strong, yet ****. Totally helpless. Her eyes strayed again to his cock, still hard and straining against his shorts. She slid her foot towards it and up over Billy's hip. She poked his hard cock with her foot. No response. Rubbed it sensually. No response other than the faintest little subconscious moan.

Professionally, Lucy felt bad for Billy. Obviously, something was going on with him. He had been getting beaten up so badly by Carly--a novice!--that Lucy had had to intervene. Then, thank god she'd sent everyone away, because she'd knocked him out effortlessly--accidentally, even!--during their sparring.

Lucy suspected his sudden weakness was due to an injury or traumatic experience. Yet he hadn't been injured on her watch, and she didn't think he boxed in any other context. Also, that didn't explain the bulge in his shorts...

Yes, professionally she felt bad. But on a deeper level, she was mega turned on at her own dominance, and it was clouding her judgment. Part of the reason she boxed at all was to beat up men who thought they knew everything. Sometimes that backfired; sometimes she'd lost to men she went in expecting to thrash and humiliate. But other times, it could be incredibly rewarding.

And this was one of those times. Billy was one of her top performers, tall and strong and fast and smart. Last time they'd sparred, she had still had a footwork and strategy advantage over him, but his strength and speed won out in a big way.

This time...well, this time was quite the opposite. He'd moved slowly, hesitantly, weakly, and she had taken full advantage. She wanted him to succeed, sure...but some part of her also wanted him to fail. At least when it came to her. This part of her wanted Billy on his knees, groveling and begging for her not to hurt him. And that part of her had won! He wasn't on his knees, he was on his back. And he was too **** to grovel. But both of those facts just made her victory more complete and certain.

And goddamn was it turning her on.

Lucy slid her hand between her thighs and clenched them tight, trying to relieve the desire in her throbbing pussy. But it wasn't enough. Not nearly. She eyed Billy's bulge again. Still rock hard.

In a smooth motion, Lucy slid one leg over Billy's insensate body, straddling his thighs. She put both hands on his cock, stretching it and straightening it in his shorts until it pointed toward his face. Then she gently lowered her crotch right onto his bulge, his erect cock pushing against his shorts and pressing against her barely-clothed pussy.

"MMMMmmmmMMmmm," Lucy moaned as she started gently sliding herself up and down Billy's cock. It wasn't inside her, or even directly touching her, but it was warm and firm even through his shorts and she slid up and down it.

Lucy threw her head back and bit her lip and moaned like a slut. She hadn't felt this good in years. Defeating Billy was something she knew she could potentially do...but she'd never done it before today.

Lucy's pussy started getting seriously wet. She continued rubbing her crotch against Billy's bulge, and she lunged forward a little and pressed her hands down on Billy's prone body. She ran her hands up over his abs, to his chest muscles and his shoulders. He didn't respond. His body was hers.

And the best part was, she knew he wanted it. Even though he wasn't conscious. She'd seen him ogling her often enough. Probably thinking maybe he could overpower her and fuck her doggy-style or something like that. Well, the joke was on him. He was utterly at her mercy and she was going to do WHATEVER she wanted to him.

And what she wanted right now was an unforgettable orgasm, so she kept rocking and sliding on Billy's cock. She thought maybe she could have that orgasm just from this clothed grinding, and she wanted to do that so that Billy wouldn't know. But after a few minutes she realized she was wrong. She needed his awesome cock INSIDE her. And he wanted this anyway. Even if he figured out what had happened, he wouldn't be mad.

Lucy fumbled with Billy's drawstrings, but quickly yanked his shorts down enough to release his rock-hard cock. She gasped as it straightened up like the mast on a sailboat. "Mmmmm," she whimpered, starting to work on her own shorts. She quickly pulled them off and sat hard on Billy's dick.

"MmmmMwwhwooaoaaaa!" she gasped as she impaled herself on Billy's cock. She started bouncing up and down and slid her hand up under her shirt, grabbing her own tit and exposing her abs. Those tight abs tightened even more as she flexed her pussy muscles and squeezed Billy's cock for all she was worth.

Pleasure ricocheted through Lucy's brain like machine gun fire. She pictured her knockout combo again, and felt the orgasm coming. She pinched her nipples, imagining her punches battering Billy's overmatched guard. She bounced up and down on Billy's dick while imagining her crisp little jabs to his face. She'd never been able to incapacitate such a big guy that way before, but his cross-eyed doofusy facial expression was one she'd never forget.

She ground harder and harder on Billy's body, caressing his chest and thinking about her knockout hook. She hadn't even meant to hurt him, not really, and instead she had ended him. At least for now.

The waves of the orgasm crashed over her, so hard they left her reeling. "Aiiieee!!!" she screamed, her body buffeted by an invisible wind. Billy stirred, but didn't wake up.

Lucy gushed pussy juice all over Billy's dick as she endured her powerful orgasm. She shuddered as it subsided, and gently let Billy's dick slide out of her as she rose.

She dabbed at Billy's softening dick with a warm towel she'd already had, then she stole off to the showers to give herself a rinse. Hopefully she'd be able to get back to Billy before he woke up.
