yaoi defied science and nature once again. . penetration without preparation, come on

I think he did a bit while peeping on Hibiki and Nonohiko.

But of course that's not enough for a virgin ass.

Right?! It always bothers me when they skip essential parts like preparation.

yap like Sensei if you added a panel of kaname-San preparing his Uke won't that be great (づ￣ ³￣)づ

Honestly, I read them for the plot more than anything. Most yaoi mangas these days have relatively realistic depictions of sex and that's why this portrayal disappoints me. Assholes are not to be treated like vaginas. Even porn gets that.
