Dominic and I were ready for our next challenge, trading underwear. Dominic immediately ripped off his clothes. When he slipped out of his Andrew Christians, I couldnt help but eye his hard-on bouncing around. We both exchanged our pair of underwear. Seeing his cock filling my underwear drove me insane, so I reached for his enormous bulge. The challenge was over too quick but I didnt want to move on to the next challenge just yet.
