Seducing 18YO str8 boy one night - Part 1 of 2

18yo boy was gonna stay overnight at our place. My roomy was already crashed so it was just us awake. I massaged him all over trying to get to see his cock. Finally when he went to take a shower, I snuck in and surprised him. I was even more surprised when he let me take a shower with him. He was so fucking hot! I couldn't wait to feel his cock swell and shoot load after load
