Anna isn’t quite done with Billy

Anna walked out of her bathroom after her shower. As she dried herself and picked out her clothes for her date with Matt her heart was singing. In such a short space of time she had found herself as a dominant woman and an athlete and acquired a devoted new boyfriend that she utterly adored.

As she looked at herself in the mirror she flexed one arm experimentally, and felt another thrill as a little bicep popped up. She finished dressing and left excitedly to go and meet Matt.

As she walked past Billy’s room she saw her defeated punching bag lying in a heap where Matt must have put him, still in Dreamland. She stopped and bit her lip. She realized she was still pissed with Billy. Sure, she had beaten him to a pulp, but she felt she needed to give him one last lesson. After all, she hadn’t been joking about owning him.

Ducking back into her room, she picked up her hairbrush, the panties she had been wearing during their fight, and a long red and white stocking she had worn for a costume party. Walking into Billy’s room, she climbed on top of her slumbering older brother as he lay on his front. Pulling his arms behind his back, she held them in place with her legs and used her stocking to bind Billy’s wrists together. Anna felt pretty sure her beating would have destroyed Billy’s strength, but looking at the impressive muscles of his arm, which dwarfed her own, she wasn’t willing to take any chances.

Anna stepped off her brother and yanked his pants and underpants down and off. Then she crawled back on top of him so she was right above his face. She slapped him gently as he began finally to stir. “Wakey, wakey Billy. I’m sorry, but I’m just not done with you. I’m still pissed about what you told Matt. Plus I think you still need to learn your new place.”

As Billy began to wake she twisted his ear and **** him up on all fours. Leading him easily in his semi-stunned state she sat on the edge of the bed and pushed him down across her lap. She felt a twinge of embarrassment as his cock pressed against her thigh but pressed ahead. The new Anna could definitely cope with that sort of feeling.

Securing him lightly by wrapping her arm around his waist, she began to spank her older, larger brother with her hairbrush. She quickly got into a rhythm, but the pain of the blows finally woke Billy from his slumber. He struggled just enough to half wriggle of her lap. Anna reacted by grabbing Billy by the nearest available handhold, which happened to be his balls. She torqued her brother back over her left leg and used her right one to control both of his legs.

Anna realized with a thrill that she was easily able to control her struggling older brother. Right now, at least, she really was stronger than him! And all it would ever take was a display of her superior boxing skills to put him right back in the same position. She decided to twist the knife as she resumed his punishment.

“You’re not strong enough to stop this, little Billy, so just accept it. Like I said, I own you now. Perhaps if you can somehow beat me in a boxing match you can change things. But I wouldn’t hold your breath.” She smirked as she saw Billy’s muscular but weakened arms desperately twist to free himself, without success. Her leglock held him so securely that he couldn’t do much else but kick his feet.

Not for the first time in the last few days, Billy’s arousal at his humiliating predicament began to short-circuit all his other feelings. His smaller, younger sister had beaten him at his own sport and was now spanking him like he was a disobedient dame in a cowboy movie. Blood pumped to his cock and he got even weaker. He wondered what Anna would do to him if he lost control and came against her thigh. The thought got him even harder.

Anna was a little grossed out by her brother’s swelling erection pressing against her leg, but also very intrigued at this fresh demonstration of just how weak he was for being dominated by the women in his life. She wondered herself if he would orgasm, and pictured herself forcing him to lick her clean if he did. Still, she had just showered. She shifted slightly so that part of his anatomy was no longer touching her.

As she switched to her bare hand, Anna noticed that Billy was no longer struggling and had begun to sob. She wasn’t by nature a cruel girl, so she gently eased off. She rolled him over so his head was in her lap, and looked down at him, a smirk on her pretty face. She cupped her hand under his chin and **** him to look at her as the tears rolled down his cheeks.

“I’m s-s-orry I said that to M-Matt, Anna. P-please don’t punish me any more.” Anna had to bite her lip to stop herself from laughing. “Ok, little Billy. I accept your apology. Though I think you should call me Miss Anna until you can outbox me.”

Billy didn’t reply but she decided to show mercy. Scrambling out from under Billy, she picked up her panties. On a whim, she rubbed them across his beaten, tear-stained face for a few seconds. Then she pinned him to his bed with one knee and tugged the panties over his legs. Billy didn’t even try to stop her, and the only resistance she had was trying to **** the panties to contain his bobbing, bright red cock.

Taking Billy gently by the hair, she pulled him off the bed, threw back the covers and **** him to lie down. The champion boxer, feared by every man who stepped in the ring with him, was as meek as a kitten. His hands were still tied behind his back, so he had to lie awkwardly. Still, Anna tucked him in very firmly, teasing Billy by rubbing her pert tits in his face as she bent over him.

“Now you look very tired, little Billy, so I’ve decided you need a nap. I don’t want to hear a peep out of you ok? I’ll come and wake you up when I decide it’s time.” “Y-yes Miss Anna”, murmured Billy, his dick still throbbing at the overpowering humiliation of what she was doing to him.

Anna laughed and gave him a final kiss on the forehead. Then she swept out of the room to her date with Matt.

Billy lay in the darkness. His hands were still securely tied and Anna had tucked him in very tightly. All that she had inflicted on him that day had drained his strength completely. Still, he had to cum. Being beaten up, spanked and put to bed by his beautiful younger sister was just too much for him to take. With a huge effort he managed to twist until he was able to hump the mattress until he finally came, soaking Anna’s panties with his cum. Billy was instantly out like a light, dreaming dreams of his dominant little sister.
