She thought she was alone, but little did she know, I was watching. My girlfriend's private masturbation session was now my personal porn. Her back arched, eyes closed, she was lost in her own world, fingers sliding in and out of her slick pussy. I zoomed in, capturing every detail, every twitch of her body as she chased her orgasm. Her moans grew louder, her movements more urgent, and just as she was about to come, she opened her eyes, catching me red-handed, my cock clearly visible in my pants.
