[Anon makes a noise at the first real bite, low and lengthy and it's part-gasp and part-laughter somehow because he is an absolute disaster honestly but he's a disaster who's intimately familiar with the wide and brilliant spectrum of physical sensation, embraces all of it like a part of himself because it is, all of it is. Natsuno's reaction feeds into his, frissons on top of the new and interesting kind of pain he's tasting and exploring right now.

Tasting his own blood is always interesting, but now it's mixed with a potent cocktail of venom and the now-familiar soft-hard intimacy of Natsuno's mouth, his tongue and fangs. And as with any kind of pain -- usually fight-related but he is definitely learning all kinds of things tonight -- it gets his blood up, both literally and in spirit. There's another soft low noise when Natsuno uses his nails and lights up a dozen other pinpricks across his skin, because Anon is nothing if not vocal, even if asking him to string a sentence together at this stage would be like asking him to pull away even a little right now.

He doesn't pull away; ignores the increasing tightness of his chest (Natsuno's grip is fierce and he pushes harder into it) and lungs and the dizzying flurry of motion as they both try to get impossibly closer. Because he knows his limits, at least he usually does, and the temperature isn't it and the biting isn't it and the blood probably dripping haphazardly into the onsen isn't it either.

They are definitely crashing past all kinds of limits but he's always loved doing that, too.]
