Physicality of a First Kiss Betrayal

As I was going to sleep a few days ago, this type of story just popped into my head. At first, it was just going to be a description of how a first kiss would feel like. But over time, as I was writing, it got deeper and I knew something would be going wrong. I haven't written in a while so it might not be too good. There are no names used in this story because it is not a fanfiction and no one in particular will be mentioned. Please think of the boy as whomever you would like. I tried to make it as generic as possible, although I was honestly thinking of Caspar Lee as I wrote it so you may find some connections to him in the story. Please remember: simplicity is beautiful.
