I know you don't mean it this way but this comes off as rape apologism.
Ash picks Lyle's safeword (a massive no-no) and it's something that Lyle does not feel comfortable saying (meaning he's unlikely to feel comfortable using it). Additionally, Lyle is terrified of disappointing Ash or Ash disapproving of him/stopping loving him. When coupled with play like this, that can easily lead to a disaster where Lyle is too scared to use his safeword out of fear of hurting or disappointing his partner.
- "He's a grown man" implies that grown men can't be forced to do things they don't want
- "Not an idiot" implies that if someone is forced to do something he doesn't want to, they're an idiot, or that you'd have to be an idiot to be scared of using your safeword or worried about upsetting your partner
Like, I'm not trying to make you feel bad or say you're a dick. Just that... as a grown man who is an SA survivor who couldn't speak out when I was being SA'd because I was scared... like... I know this is just a fictional story, but I just don't think it's good to say shit like this.

Bro. You don't have to agree or disagree about whether the scene itself is rape. That part is literally irrelevant other than the fact that OP clearly was uncomfortable with the scene and you are arguing why it's okay. It's not about the scene itself, I am strictly talking about your comment and why I felt it was disrespectful.
As much as I love the smut in this story, Karlyle lwk showed multiple times that he wasn’t necessarily fwing this whole thing.. don’t be mad at me guys..!! But I’m glad that I see so many people mentioning it.
