The word is "dong" which is a sound for clamouring~

I see...thanks

June translates it as "whump," which I took to be Akihito pushing Asami away.

If you look at the panels following (the position of Akihito's arm and body, what looks like some kind of fluid flying from Asami's face, and then Asami rubbing his lip), I think it's safe to assume that Akihito struck him.
The weird thing is the kana is different in the tankōbon than in the scan found here. Mine has the kana "don", which means "bang" or "boom", but the accompanying translation is "WHUMP!".

Huh, I hadn't picked up that Akihito had struck Asami, I'd thought he'd just shoved him away, but it seems from the sound effect that he did slap/ hit him.
I'm surprised Asami's reaction is so mild...

I'm sure he likes it, that's why I'm surprised his reaction is so mild. Often when Akihito shows defiance, Asami's all over him talking about what a turn on it is.

Yes, but it's not just defiance. This time Akihito actually struck him.... and it's not the first time either.
You know what I think? I think Asami has a deeply buried, wild masochistic streak that manifests itself very rarely and only under the right conditions... and Akihito triggered it there. The look on his face after Akihito hits him reads, "That was... HOT..."
