I was in the bathroom, minding my own business, when I noticed my stepbrother lurking outside the door. Despite my initial shock, I decided to play it cool and tease him a bit. As he caught a glimpse of my intimate area, I couldn't resist goading him to touch himself. The sight of my exposed body fueled his arousal, and he started pleasuring himself right there. I found it incredibly hot and decided to join in. We spent the next few minutes indulging in mutual pleasure, our hands moving in rhythm as we brought ourselves to climax. The sight of his cum made me even more aroused, and I couldn't resist touching myself again. The experience was intense, leaving us both breathless and satisfied. It was a wild ride that I'll never forget.
