What the fuck is he doing now?

I still don't understand what is going on.

Here's the commentary

鼻に浣腸なんて挿しちゃって。挿してしまった薬液は全部吸いだしてあげるね。それ、ズズズ～っとな

Um ... what does he do? Eats Kurodani nose? Makes artificial respiration through the nose?

Christ, man. This isn't how you exterminate monsters.

Maybe she had a cold and he's helping her unblock her nostrils.

Well in the title, it says Gaoo is apologising to her.

He's insane. He's completely insane. But why is my heart going doki doki?

Ew. Commentary's like "I put the enema fluid up your nose. Let me suck it out. *sucking noise*" close enough?

You nailed it. Also, enema fluid is usually glycerine, which is a sugar substitute and is perfectly edible. (It's why some kinds of diet candy are a laxative.)
