My sister's boyfriend secretly watches me masturbate in my room

I was in my room, getting ready to pleasure myself when I noticed my sister's boyfriend lurking outside. He had always been a bit of a voyeur, and I knew he enjoyed watching me. I decided to give him a show, and I started to masturbate. He watched with intense desire, his eyes glued to my every move. I could see the lust in his eyes as he watched me stroke my pussy, my fingers exploring every inch of my fat, hairy cunt. He was captivated by the sight of my big, fat pussy, and I could feel his breath on my skin as he leaned in closer to watch. I could see the arousal in his eyes as he watched me pleasure myself, his own hand moving in rhythm with mine. It was a sight to behold, and I knew he would be coming back for more.
