Consent can be taken back it's not absolute. The moment he puked and showed he didn't like it, consent was immediately rescinded. If your understanding of consent is this shallow you shouldn't be reading this story. Also he wanted to try it to please minyoung not because he was buzzing with excitement to get his ass pounded. That also matters. So yet it has everything to do with consent.

Y'all are obsessed with the switching thing when it's clear that cheol didn't want to do it and doesn't want to do it and his feelings on it are absolutely valid. Like I get the appeal of it but him puking put me off from ever wanting to see that shit. If it is not consensual and met with enthusiasm please just keep it.
This is why convos about consent on here are always performative cz y'all only care about consent when it's your fav bottom but when a top doesn't want such boundaries crossed all of a sudden it's "he could have just lubed him up." Utterly disgusting.
