I'm expecting the extra pages in that volume to confirm no sex happened, at least for the manga. This page could still happen if stopped them from going that far, but there's no way to know yet whether it was an immediate demand to get dressed again, or if he waited until later, or if they got him out of his clothes first too. The color page almost looks like they might have started adding nipples, but I'm not expecting that to have changed yet either. This was volume 3 though. https://litter.catbox.moe/fj9hxtsoalszreud.jpg
The WN isn't completely clear what happens although it lasts until morning.
