I cock teased my step-brother

As the night fell, I slipped into my most revealing nightgown, knowing my step-brother was not asleep yet. I strutted to his room and locked the door behind me. He sat on his bed, eyes bulging out of his head as he took in my body in the thin fabric."Well, well...what do we have here?" I purred, running my fingers through my hair. I started slowly undoing the buttons on my gown, teasing him with each reveal. His cock twitched in his pajamas and I couldn't help but smirk. When I finally got the last button undone, the gown fell to the floor, leaving me completely naked."You've been such a bad boy, step-bro," I whispered, climbing onto the bed. I slowly crawled towards him, my breasts swaying seductively. He reached out and touched her hand, feeling the warmth and softness of her skin.
