He moans at that, scrunching his eyes shut and squeezing his ass around Zagreus's finger. "You wouldn't dare."

"Wouldn't I?" he muses, massaging Thanatos's insides while teasing the tip and head of his cock. "But when I put that little toy," he continues, gesturing with his head in the direction of where he left it, "inside you and it lights up, you are going to be such a work of art. Your faces, the way your body will move..."

Second finger.

Thanatos grunts as the finger sends another jolt along his body. "What—Zag, what are you, nnngh, what are you going to put inside me?"

"You'll see. Or feel. I'm sure."

He pumps into and out of Thanatos's hole, mostly teasing and prepping for now, massaging Than's prostate and loosening him up (not that he needs much loosening, but Zag likes to be thorough).

Than whimpers then tries to clamp down on his mouth with his hands, but the collar is too awkwardly-positioned for that so he just bites down on his lower lip.

Thiiiiird finger?

"Hmmnnnngghhhh!"

He gives Than's dick a squeeze. "You're very beautiful."

Than cannot blush but he can look away from Zag.

So Zag can pull out of Than's ass and slap it. "Stay here," he singsongs.

"Yes, sir," he murmurs.

Then he returns, butt plug in hand. "Relax, lovely."

He does his best.

So Zagreus starts pushing the thinner end of the plug in until it's gone allll the way.

Than focuses on relaxing, but the plug feels like it's going to fill him up.

Until eventually it stops, and almost clicks into place.

At first, it doesn't feel particularly special, other than bigger than usual for these things. But then he understands—it starts getting warm. Warmer, warmer, hot. He whimpers, but it keeps getting hotter, and hotter, and at one point he realises he's started moaning loudly. He also notices that Zag's hand is still stroking him, and actually that he's leaking rather a lot of precum. This feels mostly abstract, though, as his awareness is almost entirely concentrated in the burning plug in his ass.

"Oh, lovely, you look stunning," Zagreus sighs, enchanted. "So now I think we can get started," he continues, getting to his feet and pulling on Than's wrists and torso to help him get up, as well.

Than almost misses those words, but they manage to make their way to his awareness enough for him to look at Zagreus with—he's not even sure what expression he's making, right now, probably something between abject terror and unbounded lust. "Get started?" he manages to say.

"Mmhm. I still have some things I want to do to you."

Zag walks Than over to a wall that has rather suspiciously-positioned hooks. He fiddles with Thanatos's collar and the wrist cuffs come detached, and he attaches them to the appropriate places at the wall, stretched to both sides and up. And at some point he seems to have attached ankle cuffs to Than, too, which he also hooks to the wall, so that Than is entirely hanging from them.

Thanatos's conscience manages to expand outwards from the burning plug around the time the first ankle cuff is being attached to that wall. He feels like he must have come at some point in this process, there's no way he's been feeling like that continuously for this long and not had a single orgasm, but a scan of the floor shows no evidence of it.

"Zag, this—this is—" Too much? Perfect? Not enough? He's not sure what he needs here but his mind is overwhelmed and whenever he can spare a thought to anything other than his direct senses he thinks only of Zagreus.

"I know, I know. I love you."

"I love you, too, Zagreus," he says, looking up at the god of life with—again, he's not sure what with, but it can't be bad, not when the love of his—existence—is right htere in front of him.

Zag walks up to Than, holding his chin between a thumb and index finger, and he lifts Than's head up to kiss him.

Than drinks up the kiss like a parched man in the desert, and this time he's aware enough to feel Zag's hand start fiddling with his nipple.

Zag gives Than's nipple one final pinch before pulling away.

Than lets out a downright undignified whine when Zag pulls away, and it speaks of how far gone he is at the moment that he doesn't even mind it that much.
