Wait, I’m confused. Are you saying that the seme is in the wrong because the uke gave him a non-consensual bj?
The seme wasn’t actively involved in the activity, rather he was being taken advantage of in his sleep. There hasn’t been any signs of him reciprocating the actions towards the uke outside of a blush from the flirting. But, the seme didn’t act upon his love during their marriage from what we’ve seen so far.
Although I do agree that sleeping with your sister’s ex-husband is an extremely morally grey situation, I think the only one who had truly participated in cheating was the uke.
To be fair yall blaming the sister and shit me too but let’s be for real. The brother did not know anything yet he still cheated with his sister husband. They are all red flags but dude is way awful than them both
