That's going to leave bruises, and half-distracts him from the pleasure he's feeling, making Ankh make an undignified squawk that he'll be sure to deny later. His neck nip to Hina's neck is rouger, a reminder that her stopping any potential roof injuries earlier doesn't matter if she's just going to manhandle them too much now, but he's quick to follow it up with a soft kiss to the spot.

But it's hard to stay annoyed with Eiji pounding into him or how hot and sharp Hina's pleasure is, which is annoying in it's own way. The feedback reaches a tipping point, and his thoughts are swept away in the stimulation overload, arms going weak as his eyes roll back, having to just trust Eiji can keep them going as he gasps into Hina's neck.
