Well they tried to do it in the very last chapter which takes place 3 years later, but even then it was Kokonoe that practically jumped him.
No he didn't because she started yelling "it hurts"
You could say that she stole his virginity instead of the other way around lol
He stopped immediately after she cried out in pain but when he said to take things slow to which she provoked him in saying something she wanted to hear and she jumped him again.
There was no yelling or anything afterwards so it's safe to assume that they did indeed lose their virginity and the story pretty much ended there.
Don't know about some of you guys but the interactions between teachers the whole series long was hilarious sometimes awkward, too bad it had to end there, as well for the anime stopping halfway of the mangathey already cut cetain bits out it seemed but i really would have liked to see the rest in anime form too.
So, i read few chapters in the beginning, and i thought " ok it got its plot, seems like it is not THAT innapropriate" and then i watch the anime, i... can't really watch it, but whatever, anyways. I recently google imaged this name and apparently the teacher DID have sex with his student... but then i see people talking about him not, which really confuses me, can anyone who knows the plot tell me if the teacher stole the girl's virginity or not..
