Basically what I said, weird no one found you annoying : ////
But glad I'm not the only one seeing things this way, thanks for adding your comment!
With healthy bdsm play, a lot of communication is needed but the problem with the two is that: they just recently met up again after high school. They haven't even delved into friendship, and they just went ahead and "tried things out" with sex. This will obviously progress to a worse situation but I want to see how the artist will handle it by inserting "love" into the mix.

They are like two kids fumbling around in the dark trying to get off.
The M has no idea what his kink is about or his limits. He doesn't even seem to have done much research and find out what he likes or not. It's not just physical pain that gets him off but degradation as well.
The S has no idea what to do but try to address the M's needs but he's in the dark. He even talks about looking things up. He needs to talk to a Dom and get hands on training about boundaries, how to read the M, knowing when not to push even if the M tells you to, and so forth.
They have a verbal agreement but nothing written in a contact and having a name for a safeword isn't really safe. Not to mention the way the M gives the S carte blanche.
But I do like how the S keeps pausing and asking if the M is alright, but he takes it as a cue to escalate and I think that's where the issue is going to come in. Because of M's kink also being degradation this is can turn into an abusive relationship without proper limits set up.
They both don't know their limits and if they continue to push things further it is going to go bad.
But, there also seems to be a love story here so I have a bit of faith they can overcome this? But they are going to hit turbulent waters soon and hard.
