I caught my stepmom in the closet, her hands exploring her body as she prepared for her anal debut. The thought of her tight hole being stretched for the first time sent a thrill through me. I hid in the hotel room, watching as she continued to pleasure herself, her fingers gliding over her soft skin. The sight of her, lost in her own world, was intoxicating. I couldn't resist joining her, my own fingers finding their way to my throbbing cock. As she moaned in pleasure, I couldn't help but imagine what it would feel like to be inside her, to stretch her tight hole with my throbbing member. The thought of our taboo act sent waves of pleasure through me, and I found myself stroking harder, lost in the moment. But as I reached the brink of ecstasy, I suddenly remembered the rules, and with a gasp, I stopped myself. Only time would tell if our secret desire would remain hidden from our family.
