Blaine looked around the party, noticing that more than one of Kurt’s colleagues was stumbling around too drunk to be paying attention to them. "You know what I've always wanted to do?" 

"What's that?" Kurt asked curiously.

"Have sex in your office." 

“Oh, do you now?” Kurt trailed his fingertips from Blaine’s shoulder to his wrist. “Alright then, let's go." 

He grabbed Blaine’s hand, and they quickly made their way out of the room, hoping that nobody saw them. Impatiently, he swiped his access card to get them past the currently unmanned security point and pressed the button for the elevator. 

Once inside, Blaine wasted no time pressing Kurt up against the wall and buried his face in his neck. 

"Fuck, Kurt. The things you do to me," he moaned as he kissed his way up his neck to just behind Kurt's ear. "You look so good tonight, and it’s been so hard to keep my hands off of you." 

"Oh yeah?" Kurt grabbed Blaine's hips and pulled them flush together. "Do tell…" 

Groaning, Blaine bucked his hips and rubbed his erection against Kurt's hip as his hands slipped round to grip Kurt's ass. "These pants, they're so tight and your ass looks so amazing in them and I keep thinking about how it feels to be buried in it. Your shoulders look so broad and strong and I always feel so safe in your arms. This shirt is so simple and yet it stretches across your chest so tightly that I'd swear I can see the bruises I left on it last night. Your tie makes your eyes even brighter than normal and I could get lost in them forever because I feel so loved when you look at me. Like I can have it all with you, for the rest of our lives." 

"You can, I promise," Kurt whispered as he rested his forehead against Blaine's and intertwined their fingers. "I am never saying goodbye to you."

The elevator dinged their arrival, and Kurt pressed a last kiss to Blaine's lips before he pulled him down the hallway to his office. He opened his office door and pushed Blaine through, flicking on the light with one hand as the other locked the door behind them. 

"Pants. Off. Now."  

Blaine had been in the process of taking off his shirt, but he left it hanging open and quickly unzipped his dress pants, pushing them and his underwear down to his ankles in one swift motion. 

Kurt pushed Blaine back to lean against his desk and fell to his knees in front of him. 

"You say I'm driving you crazy, but what about you, huh? Twirling around the dancefloor with my boss and showing off how well your own ass fills out your suit." Kurt took hold of Blaine's cock in one hand and gripped his hip tightly with the other. He licked a broad stripe up the underside and swirled his tongue around the head. "So fucking delicious, all mine." 

"Yes, yours. Kurt, please…" Blaine barely got out before he felt Kurt take him into his mouth. 

Kurt bobbed his head up and down, swirling and his tongue on every upstroke, just the way Blaine liked it. His hand was pumping the part that didn't fit, and Blaine gripped the edges of the desk tightly, trying desperately not to mess up Kurt's carefully styled hair. "More, please, Kurt, I need more." 

With his free hand, Kurt reached into his desk drawer and drew out a single serve packet of lube and a condom. 

"Do you usually have those just lying around?" Blaine asked amused. 

Kurt pulled off Blaine's cock with a smirk, "No, not usually, but I had a feeling they might come in handy sooner or later. You are many things, my dear, but subtle about what you want is not one of them." 

He spread some lube on his fingers and traced them around Blaine's hole. Kurt could feel the muscle flutter under his touch in anticipation, and he gently pushed a finger in as he sunk his mouth back over Blaine's cock. 

Steadily, he pumped his finger in and out until Blaine was relaxed enough to take another despite the tension in his trembling legs. Kurt crooked his fingers and moved them around until he found the spot that made Blaine buck his hips up with a shout. 

"Fuck!" 

Relentlessly, Kurt rubbed his fingers against Blaine's prostate as he took his length as far as it would go into his mouth, making Blaine babble incoherently. "Fuck, shit. Yes. Fuck, right there. Kurt! More, please, I'm good, just need more, please, Kurt." 

Kurt drew off Blaine's cock and swiped his tongue to disconnect the line of spit that connected the head to his bottom lip and removed his fingers from Blaine's ass. He stood up and in one motion lifted Blaine up onto the glass surface of his desk, making him hiss at the cold temperature on his bare ass.

Blaine automatically laid back and hooked his arms under his knees to spread himself open for Kurt, who wasted no time pushing his pants and underwear down far enough to release his aching cock. He quickly put on the condom and lubed up before pushing himself into Blaine's waiting body. 

Kurt's balls rested against Blaine's ass as he leaned forward, trapping Blaine's cock in between them, and he grabbed his face for a fierce kiss. He drew his hips back and thrust forward, making Blaine keen out at the sensation as he established a punishing rhythm. 

The table shook under Kurt’s unrelenting assault, but the craftsmanship held up, and before long, Kurt could feel his balls tightening. He released one of his hands from the tight grip he had on Blaine’s hips and wrapped it around Blaine’s cock, the leftover lube helping ease the friction. 

Kurt tilted his hips slightly until he found Blaine’s prostate and brought him to a babbling mess in seconds, grasping at the desk and Kurt’s shoulders for grip. “Kurt, so close!”

As much as he tried, Kurt could not stave off his orgasm any longer, and with a groan, he buried himself deep inside Blaine and let go. His head fell on Blaine’s shoulder and his hand slackened around Blaine’s cock as Kurt shuddered through his release. 

“Kurt, please. I’m so close, please,” Blaine whined, and Kurt could feel his inner muscles contracting around his still half hard cock. He leaned up slightly and tightened his hand around Blaine’s cock, giving it a few pulls before he, too, tumbled over the edge and moaned loudly while Blaine’s come painted white stripes over his bare chest. 

They laid there for a minute, trying to catch their breaths, but Kurt soon grabbed some nearby tissues and cleaned them both off. He tied off the condom and wrapped it in as many tissues as he could, hoping with all his might the cleaners would not notice anything amiss the next day. 

Kurt helped Blaine off the desk, and it wasn’t until Blaine turned around that he saw the sweaty butt print he had left on the glass surface. 

“Oh. Got any Windex lying around?”
