"No no I wasn't!"

"So you let me win? Why?"

"Not exactly." Billy looked away in shame before his sister put her hand on his face and move him back to looking at her. Billy suddenly got excited and he felt his dick lurch slightly as his sister started taking control.

"Explain."

"The gloves, the ones you used, they're not normal gloves." Anna stared at her brother waiting expectantly for an answer that would satisfy her. "They're loaded."

She looked confused. "I don't understand boxing terminology Billy, you know that."

"No no, I mean they're physically loaded. Like with extra weight."

His sister was both intrigued and confused at the same time. "Wait, so you're telling me that you cut open your boxing gloves, shoved extra weight in there, then sowed them back together?"

This was it. Billy knew that if he answered this question, there was no going back. He knew his sister would corner him into telling her why he had bought loaded gloves in the first place, the same way she cornered him into telling her what he had already told her. He briefly considered giving this up. He thought about making up a lie on the spot and running with it. But he was too flustered to come up with anything convincing, and he knew his sister would sniff out any lies he told. Plus he was horny and **** for attention, so that certainly wasn't helping.

"No. I bought them already loaded."

Anna's mouth morphed into a sly subtle smile as she realized she had her brother right where she wanted him. There had to be a reason he didn't just tell her the gloves were loaded. More importantly, there had to be a reason he bought them in the first place.

"Now why would you want to do that?" Billy remained silent for a few seconds, fearing the last step. She continued, "why would the boxing champion of the house need boxing gloves? Surely your teammates or coach would have noticed by now. Unless..." She was starting to connect the dots in her mind. "Unless they weren't for practice, weren't for you even." Billy's heart started sinking and his dick started rising. "Mom told me that you wanted to teach her boxing. That seemed weird. You were never a fan of her getting into your life. You would always handwave her interest, so what changed this time, hmm? Presumably, you would have had to buy her a pair to train in, and honestly I don't see any other pairs around the house, do you?"

Billy mouthed a soft "no" to her, confirming her suspicions. Her subtle smile shifted into a wide smirk. "So you wanted mom to beat you at boxing. No, correction, you wanted her to knock you out even!" Anna couldn't hold back a giggle as she finished that sentence. "And you wanted that either because you wanted to give her confidence in her abilities, you know build up her character. Or..." She moved her face close to her brother's so that their lips were almost touching. "Or you wanted to get something else out of this." Just then she looked back over her shoulder at his rock hard dick and smiled. "Could it have something to do with that thing back there? Big bro has a knockout fetish?"

His face went flush red. He couldn't answer the question, but that was all Anna needed to confirm her suspicion. "Oh. My. God. You do! You absolutely do!" She was basking in the glory of having figured it out.

"Anna please I'll do anything just don't tell mom." She held all the cards now. She knew it, and she knew that Billy knew it. She now had **** material like no other, and she was going to use it to her advantage.

"Fine, but first, you have to do something for me."
