Watching porn together with my stepsister and playing with her genitals leads to ejaculation inside her

I've been craving the sensation of a tight, juicy pussy for weeks now. I finally managed to convince my stepsister to give it a shot. She's a college student with a big, fat pussy that's begging for some attention. I've been dreaming about this moment for a long time and I can't believe it's finally happening. We're in her dorm room, the air thick with anticipation. I'm watching as she pleasures herself, her fingers exploring every inch of her pink paradise. It's a sight to behold, a sight that's driving me wild. I can't resist the urge to join in, to taste her, to fuck her. And when I do, it's like nothing else matters. The sensation is overwhelming, the pleasure intense. I can feel myself coming, can feel the hot, sticky release inside her. It's a moment I'll never forget, a moment that's worth every second of the wait.
