Blaine tilted his face upward, searching for Sebastian's mouth, attempting to appease the pure need that had begun surging through his body with the words, but instead found himself hissing at the sensation of Sebastian's hand gripping the back of his hair, tilting Blaine's head until the line of his neck was exposed. Sebastian's teeth hovered over the skin, threatening to graze harshly against it, but instead he ghosted upward, voice low and warning as it reached Blaine's ear.
"You need to be shown what it's like not to get everything you want exactly when you want it. Maybe then you'll think twice about parading the halls of Dalton whenever the fuck you feel like it, whoring yourself for attention like some prodigal son." He punctuated the sentence with a solid bite to Blaine's neck, only lathing his tongue over the spot once he'd added, "Est-ce que tu vas être un gentil garçon?"
Blaine nodded as effectively as he could with Sebastian fisting his hair, desperation overtaking the tiny spark of shame that had flickered in his stomach at the demeaning words. Sebastian caught Blaine's lips between his own, and it didn't even occur to Blaine to struggle for dominance when his mouth was seized by a skilled tongue. Fists coiled around the neck of his sweater as Sebastian left the chair, and Blaine allowed himself to be dragged up onto his feet, a movement that barely dislodged their mouths, but gave Blaine enough room to answer, "Oui, monsieur."
Sebastian growled at the words, hands tugging at the fabric in his grasp until it was being pulled over Blaine's head, effectively breaking their kiss. Blaine's sweater and the undershirt that had been beneath it were discarded, neither boy bothering to pay attention to where they had landed, and Blaine immediately lunged forward for another kiss. He didn't realize he was cold until the warmth of Sebastian's palms forcefully met his chest, the blonde denying Blaine access to his mouth, which was now sneering, "Avide."
Blaine literally swallowed whatever objection he had, the gulp audible as Sebastian began trailing downward. His fingers were firm against Blaine's goosebumped skin as he dragged them down the boy's torso, watching the way Blaine's stomach clenched when he traced the faint lines in his barely-defined abdomen. The reflex coincided with the increased speed of Blaine's breath, and when Sebastian glanced up, Blaine was taking in air through open, just-kissed lips. The feel of Sebastian's fingers on the outline of his erection invoked another hard swallow.
"Mets toi à genoux," Sebastian voiced, but Blaine hesitated, not wanting to pull away from the hand that was now massaging his cock through the front of his slacks. He inhaled sharply when Sebastian's free hand came in contact with his cheek, enough of a smack that Blaine's skin had a slight tingle to it as Sebastian repeated, "A genoux!"
The carpet was less forgiving than Blaine would have expected had he been thinking of anything besides the ache between his legs. Sebastian circled him once, devouring the image of a shirtless, desperately hard Blaine Anderson, on his knees in the middle of a Dalton study. Blaine's eyes noted the impressive erection in the front of Sebastian's uniform once the blonde had returned to stand in front of him, bringing his cock more or less eye-level with his hungry gaze. Blaine stiffened when Sebastian reached out a hand, wincing in anticipation of another slap, but he relaxed when his tutor merely caressed the spot on his cheek that had been abused, then dragged his thumb over Blaine's pouted lips. His tongue darted out to swipe against it, and Sebastian grinned down at him.
"That's a good boy. You'll learn fast."
Sebastian's unoccupied hand palmed his own hardness, the other continuing to rub across Blaine's mouth, catching the vibrations of a moan when Blaine saw him squeeze his length. Blaine's lips had parted to release the sound, and Sebastian allowed his thumb to slide between them. His tone was rough but teasing as he asked, "Do you need something inside that beautiful mouth?" and the response was a swirling tongue, followed by the gentle pull of Blaine's teeth along the pad of his thumb. Hazel eyes noticed the way Sebastian's jaw clenched, which only spurred Blaine on, devotedly working over the object in his mouth as though it would convince Sebastian to take off his slacks.
It did, eventually.
Sebastian was able to pop the button and lower the zipper of his pants one-handed, as well as toe off his footwear, but had to abandon Blaine's mouth in favor of fully removing the lower half of his uniform. His otherwise-crisp shirt was disheveled towards the bottom, where it had been tucked into the waistband of his pants, and only drew attention to the fact that the oxford was brushing just over the top of his thighs; it was was also tenting slightly from the throbbing erection trapped behind it. Sebastian bunched up the hem of his shirt, holding it just over his belly-button until Blaine let out an impressed, "Fuck," then let go of the fabric, inadvertently tucking the white cotton behind his cock as he grabbed the base and stroked. He teased the head with his thumb, the lingering wetness of Blaine's spit mixing with his bead of precum, and the grunt it forced from him was enough to have Blaine leaning forward, open-mouthed.
When his tutor took a step back, Blaine was too disappointed to be embarrassed by the whine that built in his throat. He had barely touched or been touched, and yet every inch of his being was begging for contact, needing to be the one earning the noises Sebastian was making as he jerked himself off just out of Blaine's reach. They were both so fucking hungry for each other, but in any other scenario, the dapper Blaine Anderson always managed to have a better grasp on battling the dirty thoughts they shared; any sign of desire could be camouflaged with a cough or a leg-cross, and conversation was always turned back to a neutral subject. Even if he'd blush, or stumble over a word or two when he looked directly into Sebastian's eyes, Blaine never broke.
Until now, Sebastian mused. The tables had turned, and he'd teach his student a lesson.
Sebastian hid the smirk creeping across his lips by lifting a hand to his mouth, spitting into it before running it over his length. Blaine groaned as he watched Sebastian's hand glide back and forth, twisting into a fist at the head before sinking back down, and, God, Blaine could do that, could make it so good for him if Sebastian would just let him. Blaine's thoughts were etched into the distressed lines in his forehead when he finally glanced up at Sebastian, but it didn't matter, because when their eyes locked, Blaine knew he had just said those things out loud.
"It's not fun to be teased with something pretty that you can't have, is it, Blaine?" Sebastian taunted, and if the question hadn't been so snarky, it could have been sad.
It was then that Blaine released a shaky breath that sounded a lot like "please," and it only took two strides before Sebastian was tapping his cock against Blaine's lips, wetting them with the fluids that were glistening on the head, and then muttering, "Ouvre."
