Isn't this just a Sub for sub? A lot of people do these, but there's also a ton of people who really hate people doing them. There are some on here who will avoid your story just because you do sub for subs, since those who are against it see it as actually being harmful in the end.
I personally don't want to take sides, but there is a stigma about Sub for subs in some of the creator circles on Tapas and I just wanted to make you aware of it.
