Anna has a few more questions

During their whispered conversation, Billy's gaze had been laser focused on Anna's body. The only light came from the moon outside, but it was enough for Billy to see the contrast between Anna's thighs and her tiny shorts, the curve of her hips, the roundness of her breasts pressing against her white t-shirt, and her hair hanging over her face as she looked down at him. At first he thought he was imagining it, but he was increasingly sure that Anna was as turned on as he was. Her voice was getting breathier, and he could see her nipples through her shirt. Eventually, she slid one small hand underneath her own shirt and reached up, cupping her breast in her hands and playing with her nipple, and also exposing part of her sexy belly.

Billy couldn't believe it. What was she doing? It was like she was in a trance. He was okay with the idea of her getting turned on by him, but he was less okay with the idea of her getting turned on by beating him up, which was kind of how it seemed based on what she was saying.

For her part, Anna was about as horny and turned on as it was possible to be, but she was still trying to puzzle out whether Billy was being entirely truthful with her. It had all seemed pretty genuine, both the boxing match and Billy's explanation, but the basic fact of her, a totally untrained woman younger and smaller than Billy, knocking him out the very first time they sparred…as hot as it was, it still didn't seem possible!

But an idea was taking shape in her head as she stared down at the spellbound Billy. It seemed pretty clear he was turned on by her…if he wasn't, he surely would have pushed her off him or at least said something. Maybe she could use his desire to extract the truth from him.

"Is this turning you on?" she whispered to him.

"Yes," he breathed back to her, pressing his chest up against her, his hands on her bare thighs.

Anna gave him a smile that was half shy, half mischievous. "Do you like…getting blow jobs?" she asked.

"Who doesn't?" Billy replied.

"Would you want one…from me?" Anna asked, a hopeful note in her voice.

Billy froze. He had barely had time to even begin fantasizing about something like this. For the past few days, he'd been consumed with thoughts of his mother, until tonight when Anna had cleaned his clock, and now suddenly she was trying to give him a blow job? It was too much, yet he knew he couldn't turn it down.

"Yesss," he whispered, their eyes meeting.

Anna hesitated now. "Well…I wanted to give you one, but to be honest, now I'm not sure. Losing to your little sister in boxing isn't really a good look. I mean, I enjoyed beating you, don't get me wrong, but I don't want to suck a guy's dick if I can beat him up. Are you sure you weren't going easy on me?"

She had him trapped, he knew. He was a fly in her web, a mouse between her paws. He could either stand by his statements from the last few minutes, keeping up the charade but giving up the chance of a blow job while simultaneously cementing his status as the submissive loser of the family. Or he could reverse himself, and tell some portion of the truth, possibly exposing his lies AND his kink for getting knocked out…all just for the chance at a blow job from his hot sister.

Billy looked up at Anna. Her hand had disappeared way up her shirt, and she was smiling down at him expectantly, like a poker player with pocket aces. Just waiting for him to lay down whatever his losing hand was and slide alllll his chips over to her.
