safe word definitely would help lol
and yeah, this is S&M in the same way 50 shades of grey is S&M. There's supposed to be rules and guidelines and trust. This is just full on torture
my money's on his sister catching them
I think there is trust at least. I've heard that the Japanese SM scene doesnt even use safe words and operate on vibes, but that it works because people are very conscious of each other. Dont quote me on that tho. It seems insane to me, but cultures are different.
In the case of this relationship, I think that they are depicted to be very in sync with each other and that this is their source of trust. Nonetheless, I agree that this series has gone away from the mostly grounded start of them discovering themselves and doing somewhat taboo stuff in public spaces to making a full on routine of it, and fantasizing about punching lol.
I guess that's fine, the author wants to write what seems to be more of a fantasy for herself than something more grounded. But it takes some adjusting for me as a reader lmao. I guess it's been like this for a lot of chapters, though. Still, I think that when it comes to SM depicted in manga, this is still one of the more balanced and wholesome depictions.
