Have you read the whole story? Nirisawa is crazy about Kabu-san. He wouldn't cheat.
Are you kidding? Narisawa is Kabul's "wife" I don't think
Koike is stupid enough to DO Narisawa. I doubt Narisawa would allow it even if Koike try to.
Koike who? He would disappear like Jimmy Hoffa if he penetrated even so much as a hole in Narisawa.
XD
LOL so funny. And that is the reason why there is no penetration xD
HAHAHAHAHAHHAHAH YES
The latest update just perfectly summed up your question. Isn't sensei great. ╮(￣▽￣)╭
WHY NO PENETRATION?
