Don't worry, I think that's gorgeous.
I don't personally scat onto clothes, I just wank into the linings, as I've mainly got a silk and satin fetish. That being said, as long as either are present, I'll get a hard on regardless of what people are doing to the garments or items.
Some things, like Leather and fur are a turn on as well because I also have a fetish for expensive items of clothing (so, coats/Jackets (my main fetish), skirts, blouses (my second main fetish mainly with silk/satin/high end cotton) shoes/sneakers/trainers, handbags and if I'm horny enough and the story is descriptive enough, socks and hats and watches.)
I mainly find pleasure in knowing that I'm dirtying or ruining something expensive or nice or new or precious.
If someone likes a jacket for example, (like you take care of yours) and it's expensive, then it's a real turn on (the idea is) to wank into it or cum on it or something because I'm violating their stuff.
So whilst I don't personally scat, the idea of you doing that to your beautiful expensive jacket and your description is really hot.
It's also hot to have people do it to their own clothes, either through being forced or willingly and showing remorse or acceptance of what they're doing. Normally, this'd come in the form of "dirty talk" where they point out how expensive it was and how it's precious and how they'd rather not, do it. In some cases, this takes the form of pleading with the person forcing them to ruin their clothing, with them continually citing the cost and what they like about it and the brand (so like, "Please, this is a £150 Zara jacket, OMG, I can't ruin this, it's so beautiful. Oh GOD, this is a £150 sheep leather Zara, OMG I'm gonna ruin it, please, no!" )
In other cases it's like what you did where you mentioned how expensive it was and how it's hot that you're ruining something you really like. Adding stuff like "It was really hot to rub my poo all over the gorgeous leather jacket, it was beautiful and expensive, god, the idea of getting shit all over this beautiful expensive jacket, knowing how much it cost, knowing how much I love the jacket made it hotter, it made it even more naughty" makes the description even hotter.
Like, it's hot seeing it, but when the person amplifies what you're seeing with verbal acknowledgements of everything they're doing, TELLING you what it's like to do what they're doing to the item and explaining in almost graphic minute detail what the item is worth to them and what what they're doing to it will do to it, the outcome of their act and the details of how the item is getting ruined, it's SUPER HOT.
So yeah, I really liked your post and your Imagefap account, wish there was video or some more description, there aren't many people in to ruining expensive clothing in general. There's even LESS that are willing to ruin THEIR own clothing and EVEN LESS that will post about it and describe the actual clothing and what it means to them.
So yeah, please, keep it up.
I think it's awesome.
