I initiated oral sex on my stepsister while she was resting on my lap

I was lounging on the couch when my stepsister plopped down on my lap. She was tired and just wanted to rest for a bit. But when she noticed the bulge in my pants, she couldn't resist. She started teasing me, her fingers tracing the outline of my hardening member. I couldn't hold back any longer. I pulled her face towards me, forcing her to take me in her mouth. She choked and spluttered, but she didn't stop. She took me deeper, her eyes pleading with me not to stop. I could feel her throat tightening around me, her lips and tongue working in tandem to bring me to the brink. And then, with a final gulp, she took me all in, her little body shuddering with the intensity of it all. I couldn't help but give in, filling her mouth with my hot load.
