I sneak into my stepsister's room and ejaculate on her underwear

After a heated argument, I sought solace in my stepsister's room. Overcome with lust, I indulged in self-pleasure, climaxing on her panties. This naughty act ignited an intense desire for her, leading to a steamy encounter.

After a steamy shower, I found myself in my stepsister's room, unable to resist the allure of her panties. I had always been drawn to their soft, silky texture and the intoxicating scent they held. As I slipped my throbbing member out of my boxers, I began to pleasure myself, my hand moving rhythmically. The sight of her underwear, so close yet so far, fueled my desire. With each stroke, I grew closer to climax, my breath hitching as I imagined her wearing them. Finally, with a groan of satisfaction, I released my load, painting her panties with my essence. The sight of my seed on her underwear, the knowledge of what I had done, made my heart race with excitement. I knew I had crossed a line, but the thrill was too intense to ignore.
