Masturbating while watching my best friend's red panties

I've always had a thing for my best friend's panties, and I've been trying to get my hands on a pair of her red ones for a while. When I finally managed to snag a pair, I couldn't resist the urge to touch them and imagine what it would feel like to be with her. As I was going at it, my buddy walked in and caught me in the act, but he didn't seem to mind. In fact, he joined in and we both got pretty wild. The sight of his cock throbbing while he was jacking off made me even more turned on. I could feel the heat rising and I knew I was close to coming. And when I did, it was all over her red panties, leaving a sticky mess that only made the experience even more thrilling. It was a wild ride, but one that I wouldn't trade for anything.
