Jay the bi guy here. Love first time stories, wished we had a way to like or comment on stories.
One of my favorite firsts with my buddy as middle teens was one night after we had decided to cum in each other's mouth and swallow. We had done this with each other twice, taking turns. That night I wanted us to cum at the same time in a 69. Back then, in the 70s, we weren't familiar with the term edging but that's what I did after we sucked each other and I was ready and he was still a minute or so from cumming. When he told me he was about to he went back down on me and we came at the same time swallowing all of what each other had. We did it that way often after that. I haven't had another buddy since and that was so long ago I'm looking for another buddy like that and in a sexless marriage.
