An Unexpected Summer Gathering with Friends

I have always been a bit of a man slut, but had never done more than some pretty vanilla encounters where we were caught fucking, plus once in college, had a nice (straight) MFM where our lady partner got all the cock she could handle. But my fantasies were realized one night. I was invited to help a guy please his wife, and he mentioned there might be another man there as well. I was a tad late, because I had trouble finding the place. Once invited in, the nekkid host apologized for starting without me, and there were clothes everywhere in their living room. He led me into the bedroom where it was in full swing (pun intended) and the lady was being spit roasted by 2 guys, while a 3rd guy on the bed was stroking and watching. So it turned out to be a 5 on 1 gangbang! It was summer, and I had flip flops and only 2 other articles of clothing (a shirt, and a pair of shorts) which were off instantly. And I was throbbing hard before they hit the floor. I watched in awe and stroked myself. Now, up to this point in my life I had never done anything with another man or any dicks. But when the guy on the bed offered his mouth, I thought “what the hell?”. He scooched to the edge of the bed, face up, and I slipped my cock into his mouth while I watched the threesome action. Didn’t take long until this guy’s cock, standing straight up in the air, caught my attention, where again I thought “what the heck?” then reached out and started stroking my first strange new (but nice) cock. Next thing I know, I was compelled to lean down and start sucking him. When the other guys both came, this guy and I moved over to service the lady, but not before her loving (& aging impotent) husband cleaned up the cream pie left there. Any way, at one point I was lucky to get in position and give head to both the lady and current cock as they fucked, all the way to them both cumming and getting to taste their mixed juices. She tasted so good, and making her cum with my tongue as he plunged into her was all time. After a few more rounds, I found myself standing at the edge of the bed as the lady sucked my cock. The same guy I had 69d with earlier came up and held me from behind as I enjoyed the fantastic BJ I was getting. In the heat of the moment his hard dick found its way up underneath me, and he started grinding on me, grazing my button time after time. I wasn’t and still am not quite ready to get fucked, but that felt really fuckin good. But... he took a couple jabs and missed, which was still hot, but made me giggle a bit. Aaaand, he tried again. So, I didn’t want this, but I hadn’t really fought it either. On his next attempt, he popped his fat head inside me. No pain because everything was super slippery, and I guess I have to admit that at least subconsciously I wanted it, because my back was slightly arched, my cock was rock fuckin hard, and my virgin hole was relaxed and ready when it happened. The look on my face was straight out of a cartoon! And I kinda freaked out internally, pushed her back, and fucked her kinda rough while the others watched our final action...
