My wife and I were going thru a divorce years ago and a good friend of mine let me stay at his for awhile. Weeks later I came home a little earlier than expected and since it was late I entered the house quietly. Right away I heard voices down the hall and listened for awhile and it was his voice and I could tell he was having sex. Then I heard another mans voice and walked quietly back to the bedroom door and saw him and another man in a 69 naked and my dick got hard right away as I watched and then saw them suck each other until both of them came and they both swallowed every drop.
I went to my room and jacked myself off and shot a huge load thinking about what I had watched them do. I went to sleep after that but woke up later to more sex sounds and went to check it out. This time my the other guy was on his back his legs over my friends shoulders and he was fucking the hell out of his asshole and he was pounding him good. When I looked closer I saw some cum leaking out of the guys asshole and I started jacking off right there in the hallway and watched my friend cum deep in that guys ass while I shot my load in my other hand and stood there until he took his dick out of tis guy and a bunch of cum ran out of his wide open asshole. My friend had a pretty big dick and this guy took it all pretty easy and let my friend pound his ass hard and cum in him.
I couldn`t sleep at all and had a hard on all night long thinking about that. The next morning he asked me how late I was out because he never heard me come in. I just told him it was very late. We talked like normal and it was hard for me not to say something to him. Two weeks went by and I just had to tell him what I saw and let him know I wanted in on the action so I just told him. He seemed embarrassed at first but as we talked he got more comfortable he became and by the end of the day he had taught me how to suck a dick and had fucked me so hard twice that I could barely walk.
We were the best of room mates for over a year and it was some very good sex.
