Look I haven't read this one, but I read the synopsis, checked the photos previews and my first thought was "is this a mrm confinement escapee ?" and went direct to the comments to confirm.
It's not just pure porn, it's the vibe and the very specific unrealistic way it's freaky. If you spent enough time on mrm you can just tell when one is from there. So yes people try to draw the line because you need to be in the mood for mrm, it's.... Peculiar.

Another MRM scape. I read this one, and I'm not proud of it. It's funny how embarrassed I get when I see this kind of BL in this site here
