I think for some yaoi sex scenes without lube, it's supposedly the uke's cum drippping down to their assholes, therefore making it 'wet'
Saaame! Especially the ones where the seme randomly eats the uke out. Like damn, I hope you washed *beyond* well (⊙…⊙ )
I sometimes just think of the "Spit ain't lube" and that has stuck on my mind everytime they put spit on the uke's asshole. To be fair Yaoi doesn't make any sense if we put logic into it
Then good on him ig
I read a comment once on a yaoi that said “Assholes don’t get wet naturally. If you’re ass is getting and releasing a liquid, go see a doctor because somethings wrong.” And that has always stuck with me and changed the way I see sex scenes in yaoi
