Edit: One improvement would be certain points in the story where the protagonist deviates a bit from the character and sounds a bit like you?
I don't remember which areas but I think it's where he's usually alone and without Buddy, maybe that could be corrected, that's all.
Very delightful descriptions of fetish content. A lot of soul packed into a short amount of time, and an excellent usage of sparse bits of art. I love how you descibe the enjoyment these characters get to expereience, it really trickles down into a cohesive analysis of ones fetishes.
