@Buraindo He does a good job of it, not the best but definitely very good. Posture and leaving parts of it to the imagination are key.
With depicting kisses, I think there's a line between it being lewd and erotic, and so messy that it turns grotesque for the observers. Of course, you always have that saliva guy who's like "but that's my fetish."
Never thought I would get a boner in this manga. Hata really upped the lewdness after Hayate.
Smell fetish hmmm. Actually, I have that as well. People calling me weirdo for smelling everything I touch and see. Definitely not toilets and trash, cause who would actually smell that?
