"I don't even want to know how you got this," Kurt murmurs, his tone a mix of irritation and admiration. Blaine smirks and brushes a stray curl out of his eyes, noticing with satisfaction how Kurt's eyes follow his movement. Kurt sniffs and turns back to appraising the manuscript, his blue eyes bright.

"The marginalia is flawless," Kurt whispers, his touch reverent even through his gloves. He's used to the things Blaine brings him - the dark-haired man specializes in manuscripts, and Kurt knows to be careful with them. He doesn't ask how Blaine gets them, and Blaine doesn't ask what Kurt does with them. They have a mutual understanding.

Kurt's eyes flit up to meet Blaine's again, and the con artist's eyes are dark with hunger.

That understanding is not limited to business transactions.

Minutes later, Kurt is pressed up against the wall of his apartment, gloves shed and fingers twisting in the back of Blaine's shirt while Blaine's mouth works on his neck. Kurt moans and throws his head back, his hands sliding down and under Blaine's shirt until he is gripping smooth skin. Blaine grins against his neck.

Kurt laughs throatily and, in a flash, has reversed their positions. Blaine is now pinned against the wall, eyes wide and hair mussed. Kurt dips his head and bites harshly at his collarbone, and Blaine whines low in his throat.

"That was for nearly screwing up my Renaissance job with your goddamn theatrics," Kurt hisses out, hands on Blaine's hips and fingers digging into the fabric of his trousers. Blaine pants out an unintelligible curse, but Kurt is already working the trousers off his hips.

"I'm going to fuck you against this wall," Kurt breathes into Blaine's ear, hand reaching in between them to palm at Blaine's erection. The normally suave man lets out a pleading sound, and Kurt takes pity on him. He slides his underwear down, smiling darkly at how Blaine's hands move to Kurt's belt. Kurt wiggles his hips and helps Blaine shed his lower garments, his own hands working to pull off Blaine's shirt.

It's only when Blaine is fully naked and writhing against the wall, when Kurt's pants and briefs are puddled on the floor, that he leans forward again to whisper in Blaine's ear.

"But you're not allowed to scream."
