Yes, this would be nothing for Ziggy's boundless energy. While for Hiroki's own it's quite a boost, and a great help sealing the holes and scars in his own quintessence.

But all that is happening unconsciously. Hiroki's whole conscious attention right now is on Ziggy.

Only one. Only one Ziggy'd be that intimate with. And sure, Ziggy might or might not have sex with other people, but in face of that, what does it even matter?

Being where they are, no deceit is possible, probably. So Hiroki knows Ziggy means it.

Also, some part of Hiroki wonders if he's left Ziggy with some hickeys, before, with all the biting. Er... spirit hickeys? Maybe a few.

And then he can barely think anymore, as this is all just too intense. Ziggy is.

Ziggy-- ahh, Ziggy--

The bonus of being here is also that he just freely 'talk' here without using his mouth. Just thinking.

Then again, Ziggy is psychic, so they can talk like that outside, too, but Hiroki's not always thinking about that clearly.

I don't think I've ever told you how much I... how much I need you. Need you. Want you.

Maybe he has, maybe he hasn't. He can't think clearly right now. He's close to coming, himself.

Maybe they should've done this in Hiroki's bed in his room, why did they leave the room, just moments ago, anyway?

But that's alright. Knowing Ziggy, doing more in bed moments from now is also possible.

But right now, Hiroki can't really think clearly about all that, anymore, really.

Ziggy, you must- ahh- be magical Hiroki thinks loudly, because with you, I feel utterly alive.

So what if he's not alive in any conventional sense, anymore, in any normal reality at least? He truly does feel completely alive with Ziggy.

And you are-- Ziggy, you are the only one I love this way, I'm sure
