My stepsister's request for a video of my penis on camera leads to arousal

After a steamy encounter with my stepsister, she requested a video of my impressive manhood. Initially, I was taken aback by the audacious request, but her persistence and flattery soon had me reconsidering. The sight of her eager anticipation and her voluptuous curves only fueled my desire. I found myself alone, unable to resist the urge to indulge. With the camera rolling, I began to pleasure myself, my fat cock throbbing with excitement. The thought of my stepsister watching, her arousal palpable through the screen, only heightened my arousal. I stroked my dick, each movement bringing me closer to the edge. The sight of my fat, chubby body glistening under the dim light, coupled with the knowledge that my stepsister was watching, made the climax even more intense. As I came, the camera capturing every detail, I couldn't help but imagine my stepsister's reaction. A wild, taboo fantasy had just become a reality.
