I tried not to go for porn on that one, I really did
“R-Rachel’s gonna be here any–ungh, oh, Kurt please, she’s gonna be here any s-second, stop t-teasing–”
Kurt slides his mouth off Blaine’s cock and licks his lips. “Not teasing,” he corrects hoarsely. “Savoring.” He’s on his knees, between Blaine’s legs and under the piano in McKinley’s auditorium, slowly jacking his brand new husband’s cock as he licks just under the head. Blaine’s clutching the piano bench for dear life, rock-hard where he hangs out of his pants and so close to coming he can taste it.
“Stop. Teasing,” Blaine grunts, putting one hand on the back of Kurt’s head and pushing him forward. He makes a low, breathy noise when Kurt laughs and takes him back into his mouth. Kurt glances back up, meeting eyes with Blaine, then holds his gaze, takes a deep breath through his nose, and keeps going until his nose hits the hair below Blaine’s belly button.
Blaine doubles over, whimpering, his hand tightening in Kurt’s hair as he holds him in place and shoots down his throat. His other hand comes up to the piano, a hideous chord clanging through the auditorium as he grasps the keys. Kurt slides off and licks Blaine clean, gently placing him back in his pants, and not a moment later do they hear two people at the top of the stairs on the far end of the huge room. Kurt frantically tries to finger-comb his hair back into place as Blaine tries to compose himself.
“Hey, Mr. Anderson! Or is it Mr. Hummel now?” Spencer’s voice rings loud and clear through the space, his and Roderick’s footsteps thumping down the stairs.
“It’s–” Kurt coughs, clearing his throat, and crawls out from under the piano. “It’s both,” he says, then widens his eyes dramatically and says, “Found it! My ring, it–it fell. Under the piano.”
“Still have to get them fit properly,” Blaine adds, discreetly zipping his pants; thankfully, he’s covered by the piano from this angle, so Spencer and Roderick can’t see anything. “Guys, have you seen Miss Berry, by chance?”
A soft, high-pitched, and all-too-familiar cackle emits from the black curtain a bit farther up the stage, and Kurt immediately turns pink and meets narrowed eyes with Blaine.
“Rachel Berry is a god damn pervert.”
