Bored and alone, I'm relieving tension in my room when my stepsister, AleksKseNy, enters to grab a book. Catching me mid-stroke, she's intrigued by my throbbing cock. I hesitate, then continue jerking off, emboldened by her interest. She watches, licking her lips, before moving closer and wrapping her small hand around my shaft. I groan as she strokes me, her inexperienced touch sending electric shocks through me. Our eyes meet, and I know we've crossed a line, but I don't care. Right now, it's just her hand and my cock, and I'm loving every second.
