Anna takes care of herself first--Billy's cock can wait.

As Anna gazed at Billy's limp, knocked-out body, she felt another surge of sexual pleasure. Unlike him, she had been turned on throughout the fight, and now she was back at the same intensity level she'd gotten stuck at when she was in her bed masturbating furiously to the memory of the first time she'd knocked him out.

Except now, there was no mental block. No longer was she bothered by the nagging question of how she'd beaten him. Now she knew how: she was just better than him. Instinctively, she knew she was about to have the best orgasm of her life. The only question was whether she wanted Billy to share the experience.

She lifted one dainty foot and placed it on Billy's chest, pressing and prodding gently. He didn't react. Still knocked out cold. She slid her foot up his chest to his neck, then his chin, then over his slack mouth. She lifted it, and gently smacked his cheek with her sole. His head lolled to the side, but there was no other reaction.

Anna pressed her hand to the crotch of her shorts and moaned. The area between her legs was starting to get drenched. It was just about time to get busy. But there was one thing she had to do first. She needed something to remind her of this experience, something concrete. Also, proof that she'd knocked her big brother out.

Anna skipped over to the coffee table that had been pushed to the side of the room. She quickly took her gloves off, squeezing her thighs together tightly to give herself a little stimulation while she was focused on her task. She grabbed her phone and brought it back over to Billy's still-inert body.

Then she sat down lightly on his chest, pausing a second to see if he would wake up. He didn't. It had been a solid couple of minutes, and if Anna weren't so distracted marveling at her own victory and pleasuring herself, she would have been worried about him.

Anna took a selfie of her straddling Billy's chest. She had one arm flexed, and although she didn't have a lot of definition, there was still a slight but noticeable muscle there. She had to bend low to get her arm, her face, and Billy's face all in the frame. When she examined the picture, she noticed that she was bent so that her boobs were practically popping out of her sports bra. At first, she was a little embarrassed, and her face turned red. But then, it started just making her more aroused. Her obvious, in-your-face cleavage in the pic just emphasized the fact that she, a woman, had beaten her boxing brother into submission. In the past, she had been very modest, but now she felt herself embracing her own sexiness.

At this point, Anna could no longer hold back. She tossed her phone aside, stood up just long enough to peel her shorts and panties off, and then sat her bare ass down on Billy's chest. She started by just sitting there and touching herself, but quickly realized that she was going to have to sit right on his face. It was the only appropriate way to punctuate her victory, and she knew from experience that it was her favorite way to cum.

Just before she slid forward onto his face, she saw his eyes open halfway.

"Whaaa...? Whaaa happened?" Billy slurred.

Anna felt a thrill run through her. "I beat you. I fucking beat you WITHOUT the loaded gloves!" she exclaimed triumphantly.

"Noo....I don't believe it," Billy groaned weakly. He was struggling underneath her, but she knew she had weakened him too much--pinning him down was easy now.

"You better believe it, bro!" she said, and booped his nose with her finger for emphasis. "And you want to know something else? You liked it! I know you did!" Billy started pawing at her thighs, trying to push her off his chest. Anna easily grabbed his wrists and slammed them to the floor, leaning over him to make sure her weight kept him pinned down.

"I was thinking...since I was going to give you a blow job if you won, and instead I won, it only makes sense for you to eat my pussy, right?" Anna asked.

Billy's face went red, and he stammered "Um, uh, I don't---".

Anna let go one of his wrists long enough to press a single finger against his lips. "Shhhh," she shushed him, a little condescendingly. "It's okay, I know it's hard for you to admit how bad you want me to sit on your face. Just nod if you want me to do it," she said.

Billy just stared at her, eyes wide like a deer in headlights. Anna grabbed a handful of his hair and shook his head yes. He didn't resist. "See? That wasn't so hard, was it?" she asked, laughing.

And with that, she moved forward those last fateful few inches, placing her drenched pussy right on Billy's mouth. She immediately threw her head back, consumed by pleasure. She started moving her hips, sliding forward and back on her defeated brother's face. She let go of his wrists, and his hands drifted up to her hips. For a moment she thought he was trying to fight her still, but it turned out he was just trying to ease some of the pressure and sync himself with the rhythm of her body.

Anna arched her back, one hand drifting up and cupping one of her breasts. After a moment, she grabbed the bottom edge of her sports bra and pulled it up over her breasts, which started bouncing alluringly along with the rhythm of her hips. She pulled it all the way off and tossed it onto the couch. She wished she could see her own sexy, naked, conquering body from Billy's point of view. She started moving faster, knowing that she was close to the ultimate orgasm. She pressed hard down into Billy's face, smothering him with her perfect pussy. God, it felt good!

Finally, she felt the wave of her orgasm wash over her and carry her mind away into an explosion of pleasure. It hit her again and again, her pussy and abs contracting rhythmically and involuntarily. Her moans turned into screams as she threw her head back. "Ohmygod! Ohmygod! Yes! Yes! Yessssss!" she shouted, no longer caring who might hear.

After the last "yes," the overwhelming pleasure finally subsided, and Anna was able to relax. She slid back off Billy's face to give her poor brother a chance to breathe. He stared up at her, dazed and in awe.

"please," Billy murmured, in a voice so quiet Anna could scarcely hear it.

"Please what?" she asked, playing dumb.

"please," Billy repeated, squirming slightly underneath her. Apparently he was still too weakened to utter more than one word at a time. It was okay though--Anna knew exactly what he wanted...his own release. And she could give it to him so easily, if she chose to. Anna held complete power over him in this moment, she knew.
