Summary: Ritsuka has terrible taste. Camazotz wants a priest.
Notes:

It's well known that Ritsuka is quick to forgive former enemies. As soon as he summons them as a Servant and they're not actively trying to kill him any longer, he treats them the same as anyone else in Novum Chaldea. He's summoned four former Beasts, five if you count Koyanskaya twice, and he trusts them with his life in battle.

Less well known, but probably not unrelated, is that Ritsuka has absolutely garbage taste.

When he met Camazotz, it was a bad time for gawking, given that he'd just badly injured Kingprotea. Now that Camazotz is his Servant, Ritsuka has no reason not to stare at his tattoo-covered chest, his sweeping wings, his long tongue that darts out to wet his sharp teeth.

Well. He has a reason, in that Camazotz is deeply unhinged and violent. It's just not a good enough reason to stop him from fantasizing about what he could do with that second mouth on his throat.

"Priest of Chaldea," Camazotz says, interrupting Ritsuka's increasingly degenerate thoughts. "Your blood is roused by my presence."

Ritsuka feels his face go red. It's true, but this is the first time he's been called out that directly. "-I'm not a priest of anything. My name is Ritsuka," he says, because there's no way he's actually going to respond to the rest of what Camazotz said.

"I remember your name." Camazotz's eyes lid as he watches Ritsuka's reaction. "What a waste it is, that you're not a priest. I would make you an acolyte of mine, if no other god has claimed you."

"What- does being your priest mean, exactly?" He has been a lot of things to a lot of Servants - a lord, a bellwether, a patron, a Roman citizen - but as far as he can recall, this is the first god who's invited him to be a priest.

Camazotz smiles, tongue lolling to one side. "An offering of praise. An offering of flesh."

"I can do praise, but I don't want you to drink my blood." Even that would be fine if it was just a sip, but he doesn't trust Camazotz to have restraint.

"No, no, no. I take blood from my sacrifices and my prey." Camazotz reaches out and tilts Ritsuka's chin up with one clawed finger. "My priests freely offer me their flesh, and I reward them with my own."

Ritsuka is almost completely sure this is a sex thing and not a mutual cannibalism thing, and the remaining risk is worth taking. Mostly because he's half-hard already and he doesn't think he could manage an answer that isn't, "Okay. Where do I start?"

Both of Camazotz's mouths have tongues, and the one coming from his neck is just as long and flexible as the first. It wraps around Ritsuka's cock, winding all the way around it twice over.

"Sing for me," rasps Camazotz. "Worship me. Cry to the heavens!"

Ritsuka doesn't need much encouragement. "Camazotz, Camazotz, oh-"

Camazotz's second mouth stretches as wide as it can on his neck to swallow Ritsuka's cock. Teeth threaten just a millimeter from his skin.

"Don't move, or I'll taste your blood." Not that Camazotz has any fear of that as his throat ripples around him.

Staying still might be the hardest thing Ritsuka's ever done. Camazotz's throat is hot and tight, and even the thought of being sliced open doesn't completely quell the urge to thrust deeper. His hips quiver almost imperceptively.

"Fearless? Foolish? I'll graciously reward either."

Ritsuka's cock slides in and out of Camazotz's neck, just barely avoiding a brush with teeth each time. It shouldn't make Ritsuka's pulse race the way it does. He can't hold back his moans, and he wouldn't try to anyway.

"Good, good. You worship me well, priest." Camazotz watches him with his other mouth set in a smirk. "Offer more to me, more, more!"

"Camazotz-" Ritsuka's voice breaks. "Please, I can't-"

"You can. You will. Give your everything to me, Ritsuka."

Of all things, it's Camazotz calling him by his name that makes Ritsuka come down his throat with one last cry of his name. Camazotz swallows it all, only releasing Ritsuka's cock from his second mouth once he's satisfied that Ritsuka truly has given him all he has to offer.

He doesn't give Ritsuka a moment to rest. Camazotz pounces on him, pinning him with his back to the bed, wings spread out like a canopy over them both.

"I have accepted your offering," he says, while his other tongue licks his mouth clean. His loincloth does nothing to hide his excitement, nor his size. "Now, my priest, you must take mine."
