Not too long ago, I was invited by a friend to an all male social. I knew he was a naturalist and I wasn't overly surprised that the social was clothing optional. Aside from a high school locker room after PE, I had never been naked in front of more than one person at a time. Well, here I was, fully naked in front of 9 men sitting around chatting. To me, that was kinky. Several of the guys began getting physical and several more joined in. Noticing my reluctance, the host indicated that I could stay, join in, just watch, or I could leave anytime I wanted. Although I found it very exciting, I chose to leave because I was having a bit of a hard time accepting the concept of group sex with people I had only met a hour ago. The host was very gracious and said I would be welcome at any future gatherings.
With the thought of that evening firmly planted in my memory, when the next invitation came along, I accepted. There we were, chatting in the nude again. As before, the guests began to become intimate. One gentleman, I'll call Mark, sat next to me and began to caress my chest and gently squeeze my nipples. I froze and told him I wasn't ready yet. Mark smiled and reassured me that no one at the gathering would do anything against the wishes of another. He moved on to another guest leaving me to be a spectator. I watched as the group engaged in oral and anal sex while switching partners from time to time. As I watched, I became quite excited and instinctively began to stroke my erection knowing that it wouldn't be long before I reached a climax. Mark, who had been watching me, moved close and, with a smile, asked "Are you ready now?". "Yes" was my answer as he gently and expertly drew my erect cock into his warm and inviting mouth. With a beautiful rhythm and a very active tongue, it took very little time to have an explosive orgasm with Mark anxiously taking in every drop. Well, I was done for the night and left feeling guilty that I hadn't reciprocated.
The next invitation came a month later. We gathered at the same residence, disrobed, and chatted together. Mark was there, and when the group began to engage, I moved over to him with intentions of showing my gratitude. We talked and caressed each other for a while and I then moved down to take his growing erection in my mouth. Before long, we were in a 69 position with me on the bottom enthusiastically sucking his engorged member. While doing so, another beautifully erect cock entered my view of Mark's balls and hole. The cock hovered above my face for a few moments then, with a push, entered Mark's hole and smoothly slid in up to the hilt. Now I had Mark in my mouth and was watching two sets of balls slapping against each other with an absolutely, close up view of anal fucking. If that wasn't enough, at the same time, my ass was being lifted and I felt cool lubricant being applied to my own hole. Moments later, I was being penetrated by another guest's ample erection. The four of us were busy for a while!
I'm thinking that I went from zero to kink in a very short time.
