Not only did Blaine drop his mouth open immediately, but he extended his tongue until it was flush with his chin, and blinked up at Sebastian with eyes that were legitimately golden. His tastebuds caught the barely-there bitterness of precum as Sebastian rubbed his cock across his tongue, and what would have been Blaine's moan came out as a humid breath of air that caused Sebastian to shudder. With the pressure on his tongue, Blaine wasn't able to swallow the saliva pooling in his mouth, and a small rivulet of spit ran down his chin when Sebastian actually thrust inside. For a moment, he thought Sebastian's extending hand was going to wipe it away, but the thought was fleeting, and Sebastian merely smeared the wetness up Blaine's jawline and onto his cheek, smirking at how debauched the normally put-together boy looked, messily sucking his tutor's cock. To complete the aesthetic, Sebastian tangled his fingers deep into Blaine's hair, mussing the gelled curls as he began to force Blaine's head to bob up and down his length. The first and only gag was purely out of surprise, but it still had Blaine's amber eyes watering as he took Sebastian into his throat.
"Is this what you c-came for, Blaine? Did you want some more fucking attention?" The question seemed to wash over Blaine in a wave, and when his gaze wavered under Sebastian's dark stare, it was clear what his answer would have been were he able to respond. He suddenly brought his hands to Sebastian's thighs, gripping at the edges of his shirt like a lifeline when Sebastian gave hard, lasting thrust, but when the blonde withdrew completely, Blaine's fingers didn't seem to relax. Sebastian gave a lovetap to Blaine's dry cheek - "Je t'ai posé une question." - and Blaine was strangely grateful that his eyes were already glassed over as he was forced to answer.
"Oui, monsieur."
His voice was low and rough from the throat-fucking he had endured, and Sebastian's cock gave a subtle twitch at the sound. The movement caught Blaine's eye, and, God, it was so much easier to focus on sinking his mouth back onto Sebastian's length rather than acknowledge the messiness of his own emotions, but he was unable to do either when he felt a demanding tug in his hair. Blaine tried to get to his feet, but Sebastian was too impatient to wait for him to fully stand before slamming their lips together. The force jolted Blaine slightly off-balance, but an arm locked around his waist so tightly that it may have felt protective had the events of the next five seconds not occurred: Blaine literally sank into Sebastian's kiss, letting the taller boy's frame keep him upright until his knees were steady, and his fingers were groping for purchase when they landed on Sebastian's tie. Forgetting himself, Blaine yanked at the knot, desperate to uncover more of Sebastian's body, and -
Blaine was only beginning to realize that Sebastian was snickering when he found himself walking backwards until he collided with the edge of the desk Sebastian had just cornered him against, the sturdiness of which proved impressive as Sebastian trapped Blaine's body against it with his own. The throbbing need in Blaine's cock was miserable, and when Sebastian began rocking their hips together, Blaine grunted so loudly that he almost missed what his tutor was saying.
"The only way this tie comes off is if I decide to take it off, and if I decide to take it off, it's going around your wrists," Sebastian explained, his tone nonchalant as he twisted his posture until Blaine was straddling his thigh. He allowed Blaine to continue rocking, chasing whatever friction he could while Sebastian calmly brought a hand up to cup his chin, demanding eye-contact. What he found in the blown pupils was a combination of yearning and desperation, with just the slightest edge of unease, and Sebastian awarded himself a tiny victory, because that was everything he felt whenever Blaine Anderson came around. Sebastian loosened his tie just an inch more, smirking when Blaine widened his eyes and rambled French apologies that weren't properly formed.
"Tu es un petit cochon," Sebastian whispered, the message delivered in a tingling breath against Blaine's ear. "Now, turn around, and bend over the fucking desk."
Blaine followed the order as soon as Sebastian had backed off enough to give him to room to do so, stroking his cock almost absentmindedly as he observed Blaine's movements. He cleared his throat when Blaine dipped slightly at the waist, leaning against the desk's surface on braced hands. Blaine threw a glance over his shoulder at the sound, and lowered himself onto his forearms, which caused his ass to stick out further, but Sebastian tsked and stepped forward, shoving a hand into Blaine's shoulder-blade to force his torso flat against the desk. Blaine winced at the coolness of the wood beneath his stomach, which ebbed as he tried in vain to even out his breathing - he could see his heated breaths making patterns against the wood with every exhale - but the temperature felt good against his forehead when he ultimately dropped his head in submission; that happened the millisecond Sebastian's hand made its way to the front of Blaine's pants, fingering the button and zipper until they were out of the way, and the fabric could be tugged down to Blaine's knees, along with the navy boxer-briefs that had been hiding underneath.
The study had one small window, mainly decorative, meant to dispel the feeling of imprisonment in the otherwise secluded room, and the sight a passerby would have stumbled upon had he peered through the glass was obscene: Blaine white-knuckling the far edge of the desk he was stretched over while Sebastian knelt behind him, still donning his shirt and tie, spreading the cheeks of Blaine's ass before leaning forward to tease the tight opening with a firm swipe of his tongue. Blaine gritted his teeth against the feeling, fighting whatever noises were bubbling higher in his throat with each lick. It wasn't until Sebastian nudged the tip of his tongue inside that Blaine released a guttural sob.
"Gah!"
"Naughty boy," Sebastian growled again, this time in English, as he got back on his feet. He promptly sucked a finger into his mouth, coating it with saliva before tracing Blaine's hole, lightly pulsing at it without actually entering. Blaine's naked muscles strained in pure want, and watching the tension build in his student's body momentarily distracted Sebastian from what he was doing. Blaine was a fucking wreck by the time Sebastian slid a finger into his tight heat, and he melted into the wood, whimpering at the relief of being somewhat filled. That seemed to refocus Sebastian, who masterfully warmed Blaine up until he was hungrily fucking back against three of his tutor's fingers.
"You need my dick, don't you? Have you learned your lesson, Blaine, huh? Do you know what it's like to be so fucking close to something and not be able to have it?" The interrogation only paused long enough for Sebastian to spit into his hand, transferring the slickness onto his cock as he continued.
"What if I walked out right now, left you here exposed and unfuckingwanted, like a toy I got sick of playing with? Is that what I should do, Blaine?" because, fuck, it wasn't fair! It wasn't fucking fair that Sebastian had to compete with the ghost of some asshole who'd abandoned Dalton on a goddamn whim, who dropped in on rehearsals that he was no longer a part of to boast about his lead in his new school's musical, further reminding everybody of how flawless he was, and then Sebastian had to find out that the "whim" was some pretty little twink, and that even if he could lure Blaine out for coffee or dancing or whatever other trick he had up his sleeve, the golden eyes and gorgeous lips and infuriatingly perfect everything were taken, and it wasn't fair!
Sebastian didn't remember sheathing himself in Blaine Anderson, but he was suddenly hyper-aware of the merciless grip he had on the dark-haired boy's hipbones, the drabble of "God, fuck, I'm sorry, just please, Sebastian, please don't stop" coming from beneath him, and the mindblowing sensation of Blaine shattering around him as he climaxed against the underside of the desk, and then Sebastian was cumming harder than he had in his entire life.
Once the cell phone reading "1 missed call" was back inside the pocket of Blaine's straightened pants, and glasses were again masking the already unreadable emotions in Sebastian's eyes, a stray napkin from the wastebasket was used to wipe away whatever physical evidence of their lesson had been left underneath the desk. Sebastian unlocked the door, holding it open for Blaine, who tried to pass through when he was promptly stopped by a hand on his chest. Blaine pulled his gaze from the carpet to his tutor's face, which looked blank as Sebastian reached up to smooth a few rogue curls that hinted at Blaine's activities. The hand didn't linger, immediately gripping the doorknob as he nodded for Blaine to leave. Sebastian barely shut the door behind them before striding away, once again leaving Blaine to stare after him.
"Hey."
Had he not been the one on the receiving end of everything, Blaine never would have guessed that Sebastian had just had rough sex against the desk of a prep school library. He looked handsome as fuck as he casually turned around, hands in his pockets, eyebrow quirked at Blaine in a silent, "What?" and it wasn't the first or last time that Blaine was almost too taken aback by Sebastian Smythe to speak. Nothing he actually wanted to say seemed right, so he settled for the obvious.
"We - you're supposed to lock the door."
The arrogant half-smile made an appearance as Sebastian took a few steps back towards Blaine, leaning forward in fake secrecy. His stage-whisper seemed deafening in the abandoned space as he confided, "The door needs to stay open, because that room smells like sex, and my name is on the sign-in sheet."
Blaine felt his smile mirroring Sebastian's, and the two fell into a weirdly comfortable silence as they walked together, neither chasing after the other. Whatever unresolved issues would rekindle the guilt in Blaine's gut on his drive home, or follow Sebastian to bed that night, would have to be resolved at their next lesson.
