Heya,
So first off, thanks for the long-time follow and thanks for the continued interest in the story. I do agree with the "experimentation" that you referenced. Without adding any spoilers since a lot of people check these comments before they even download, there is some experimentation in the story-- even if much of it is talk and just trying to figure out their boundaries. That being said, all of the adult content in the story is specifically dropped in there to push the story forward or setup something that's referenced later. You mention things like bondage, which does open up some potential conversation points (probably like consent or things like that). However, there's very much a control component there and for a story where the guys are trying to figure themselves out, it seems like a bit of a stretch for them to assume that much dominance. I think a lot of their scenes together are more like cat and mouse where they'll try something and then pull back afterwards.
Another concern here is that despite the project being adult, I didn't want to go too heavily into sex or kink stuff to the point that it distracts from the plot and just becomes porny-- which is why much of the content is super vanilla. I'm also a very vanilla guy in general, if you asked me to write a bondage scene, I have no idea how to even write it. Given the internal monologues and stuff throughout the game, I'd want that present in that scene just as much as any other but I have no idea what Zack would think because I'm not a bondage fan. Literally triggers a fear response and i'm not sure how I could get myself into the headspace to write a scene like that. In other words, I'm definitely not the guy to write a scene like that and I doubt I'd do it justice in any way. lmao
