Young stepbrother masturbates while annoying me

As a young guy, I've always been a bit of a pervert. I love to tease my stepsister, a petite and adorable 18-year-old, by walking in on her while she's changing or taking a shower. I know it gets her all hot and bothered, and I love to see her blush and try to cover herself up. One day, as I walked in on her again, I decided to take things up a notch. I knew she was watching me jerk off in my room, and I decided to put on a show for her. I walked out in the hall, still stroking my hard cock, knowing full well that she was watching. The sight of her blushing and trying to look away was just too much for me. Suddenly, she couldn't resist anymore and rushed to me, eagerly taking my monster cock in her mouth. The sight of my stepsister deepthroating me was just too much for me. The thought of it still sends shivers down my spine.
