My friend is housmates with my gf. I've been with my gf for almost a year but I can't stop thinking about our friend. Every day when I'm with them it's constant. When they were both out I took the hottest looking pair from my friends panty drawer and went to the bathroom. It took my seconds to get fully hard and I came the most I ever have in my life with them in less than 2 mins thinking about me and our friend.
