I'll try my best.

。。。え何この状況？
...Eh? What is this situation?

これは。。。頂いちゃっても良い感じ？
This is... the feeling that even if we eat this it'll feel good?

でも解いても殺しにくる雰囲気だし。。。
But even if we unbind her, there's an atmosphere that she'll come and kill us...

いや普通に捕まるからな？
No, because we'd normally be arrested, right?

いやダメですよ
早く解いてあげましうよ
No, it's really no use!　Let's hurry up and unbind her!

据え膳食わぬは男の恥！
To not eat a meal set before oneself is a man's shame!
(TL: This is a pun. 「据え膳」 means both, "A meal set before oneself, as well as "A woman's advances", while 「食う」 means both "to eat" and "to have sexual relations with a woman")
