Holy shit, the morning after is... something. This all happend over the course of about 3-4 hours at his place last night. I think I left his place just before midnight. I went over to his place after my wife went to work last night and of course we were both awkward about the whole thing for a bit, and we both wanted to discuss it kind of quickly but were feeling each other out for a bit while we did other things. He eventually broke the ice and we talked about it for awhile, like the implications of being married to his sister and what not. Heavy shit, but there's been sexual tension for so long between him and I that we eventually just decided we felt comfortable to "experiment" and keep it entirely discreet but only occassional, and to not let it become some repeated thing that we are doing often or any chance we get.
So step one was telling the truth to each other about our past experiences with guys, and we both have done some general touching and oral with guys in the past but nothing too far. We talked about that for a bit and then moved into some of our fantasies, desries, etc and that's when we started getting noticebaly hornier. We grabbed some drinks and kept talking through it all.
We reached a point where we agreed that if we wated to experiement and were going to be discreet, we might as well throw on some porn and just go for it. I mentined a BBC fetish to him so he put some of that on, and we started touching oursevles, which eventually led to whipping our dicks out and jerking together.......... which eventually led to me going for it again and grabbing his cock. He grabbed mine after some time and we just started jerking each other. From there it escalated into grabbing some oil and using that on each other, squeezing each other's cocks in our hands, just playing around more innocently.
I asked if he felt comfortable shooting a load, and he got bold and said something like "yes, but do you feel comfortble with it in your mouth?" - paraphrasing here. My whole body tensed up with excitement. He suggested we take things to the shower which was a hot idea, and so we did. Excitement for both of us went up to 100 in the shower and we did nothing but jerk and suck while we were in there. I finished him off sucking his big dick until he shot down my throat, and he returned the favor and let me shoot down his. Hottest fucking thing of my life by far and I can't quit thinking about it this morning. Good news is we left things a bit less awkward than the first physical encounter.
Sidenote: I remember a long time ago when we worked together at a restaurant in college, he was in the kitchen and jumping up and down over somehing, some girl who had the hots for him mentioned when he was jumping up and down she could see his dick flopping and that it looked big. It was kind of a running joke for a bit after that. Let me say, she was not joking and that dick did not disappoint last night.
