Wrestling my stepsister

She pinned me, without having to grab me by the balls. For the first time.

Amy slowly disengaged and stood up, standing over me as I blinked up at her. She was still naked, gorgeous and naked, standing there sweating. An attraction that had only been a joke before now started churning its way through my gut. Somehow, her defeating me in a fair fight had made me lust after her in a way that all our naked hijinx before had not.

But that was a bit beside the point, I thought, because now she was going to make me take my medicine. Dreading what came next, I stood up and, without her having to tell me, spread my legs and put my hands on my head. Amy caught her breath, then stood in front of me, her black hair falling in sweaty tangles over her pretty face.

“Go on,” I said. “Good job, you wrestled great. Now let’s get this over with.”

I almost peed myself in fear as she slowly reached her hand toward my balls. She gripped them, and started to roll them gently around in her hand. Embarrassingly, my erection started twitching back to life. Then she started squeezing, and a bit of pain shot through my gut. I realized suddenly that even the times when I had beaten her at wrestling, she had had the power to do this to me at any time, and she had refrained. At that thought, my erection returned in full, and I winced in both embarrassment and pain.
