I am ERECT

Doesnt the guy say something like "you can do whatever you want with her, just dont let her escape"? he sees them on the bed together and thinks shes fucking her, right?
Like the guys pov is that shes using the p.o.w. for fun.

Seems even google translate says something like that on the japanese as well as the chinese version.

so i think she either dragged her into another bed in another room, while naked, in the few seconds it took the guy to arrive, or they are in the bed we see int he beginning, and this translation is completely wrong and changes the story for no reason.

Can confirm.
The original text from page 5 (checked from pixiv) says:
遊ぶのは勝手だが逃がすなよ

roughly chopped off:
遊ぶの // は // 勝手だ // が // 逃がすなよ
to play / to mess about // is // one's own convenience // but // not let go / release (逃がすな, 逃がさない, negative form)

Which tends to confirm the translations from both google and deepL ("You can play, but don't let her go" and "You can play all you want, but don't let her get away." after correction)
