Kurt didn't plan it. He didn't even realize what he'd done until Blaine was on the leather sofa next to him with his ears flushed pink with . . . arousal? Humiliation? Probably both, if he was being perfectly honest.

Kurt didn't plan it but they'd just come off a very intense weekend of play and the edges between master and boyfriend apparently hadn't quite gelled yet. One minute he was sitting on the couch wishing Blaine was next to him instead of a few feet away deep in conversation with one of the other Ph.D. candidates from his department, and the next he was saying “Blaine” in that tone of voice, and jerking his head toward the empty seat next to him.

Blaine only froze for a microsecond – no one else would have even noticed it. He smiled at his companion and murmured something then sauntered across the room and settled next to Kurt on the sofa. He was perfectly composed; only his ears gave him away.

Kurt was more than a little shocked himself. And yet . . . he'd liked watching Blaine respond so quickly to his command in front of everyone. He'd more than liked it. It didn't matter that barely anyone at the party had noticed it, it had happened, and Kurt wanted more. Blaine eyes meeting his were wary but not alarmed, so Kurt held up his glass between them.

“I need more wine.”

Blaine nodded. “Okay,” he said, reaching for the glass.

Kurt held onto it and raised an eyebrow. He watched Blaine's trembling inhale and challenged him with his eyes.

“Yes sir,” Blaine said, quietly, but loud enough that he could be heard, if anyone happened to be listening.

Kurt surrendered the glass and Blaine rose and headed toward the makeshift bar. His ears had gone full red, and the flush was starting to bleed down his neck as well. Kurt's belly was hot with desire, watching his boy obey him in front of everyone. No one was actually paying any attention, of course, but he knew, and Blaine knew, and that, apparently, was enough.

While Blaine was gone another student plopped down in the armchair next to Kurt's sofa and introduced himself. They were deep in the requisite “how did you end up at this party” conversation – Kurt with only half of his brain as the other half was busy praying he hadn't pushed Blaine too far, too fast – when Blaine returned with Kurt's glass full of red wine.

His eyes widened when he saw the other student sitting so close, another tiny signal that Kurt was sure only he noticed. Kurt smiled at Blaine as he approached but he didn't speak. Whatever happened next was up to Blaine.

Blaine stopped in front of Kurt and though he angled himself slightly away from the other young man, he stayed on his feet as he handed Kurt his glass.

“Thank you,” Kurt said. He tried to make it sound like a dismissal.

Blaine stood still, not taking the out Kurt had offered him. There was too much white in his eyes, like he was on the verge of panic, but he held Kurt's gaze and asked, “Is there anything else I can get you . . . sir?” His voice shook like a leaf in a gale and for a moment he closed his eyes and hung his head, gasping sharp breaths in a familiar way that Kurt couldn't quite put his finger on, until it hit him like a sledgehammer between the eyes.

Blaine was trying not to come.

“No.” Kurt had to keep his reply short so his own voice didn't break as badly as Blaine's. Because they were deep, deep in uncharted territory and he was sure that Blaine needed him to be in control now more than he ever had. He tilted his head toward the empty half of the sofa. “Sit.”

Blaine sat. He folded his hands in his lap and lowered his eyes to the floor.

Not sure what he was supposed to do next, Kurt turned back to the student in the armchair, who he only just now realized was wearing a submissive's cuff on his right wrist. And sort of looking like he was trying not to come too.

“So you were saying?” Kurt said, as if nothing at all unusual had happened. The boy stammered out a reply but Kurt was only listening with half his brain. The other half was praying that Blaine, sitting in silent submission beside him, wasn't going to kill him as soon as they got home.

*���� *���� *

“Swear,” Blaine panted.

Kurt opened his eyes and found to his surprise that they'd actually made it all the way to the bed, although the decorative bedspread and shams were most definitely underneath him and not out of harm's way on the chair where they usually ended up. He and Blaine were also both still dressed, although all the important bits were exposed. A trail of discarded outerwear was scattered between the door and the bed.

“What?”

Blaine's face hovered into view above him, out of focus but obviously demanding. He didn't seem to care in the slightest that Kurt was still trying to recover from having his brains sucked out through his dick.

“Swear. Solemn vow. Unbreakable.” Blaine kissed him hard and Kurt moaned, because his cock was trying to twitch to life again and that was so, so not a good thing.

“Can't this wait at least until the feeling comes back in my legs?” he protested when Blaine's lips released him.

“No. Now.”

“Pushy,” Kurt admonished, but he had to admit he was finding pushy Blaine very compelling. He wrapped his arms around Blaine's chest and flipped them so that he was on top, his soft cock pressing against Blaine's still very much hard one. “Okay. I, Kurt Hummel, do solemnly swear that I will find more ways to dominate you in public.”

“And never hold back . . .” Blaine prompted.

“And never hold back because I'm afraid I might be pushing you too hard. And always take just what I want from you no matter who else might be around.”

Blaine moaned and thrust against Kurt's cock, which was definitely getting hard again.

“You promise? Really?”

“Blaine, you trying not to come in front of a room full of people is one of the hottest things I've ever seen. And that's a really high bar. I guarantee it's going to happen again. Is that enough of a promise?”

Blaine made a show of considering, then shook his head. “I feel like we need to seal it somehow. Like a blood vow or something.”

Kurt grinned down at him. “I have a better idea. Something even more precious than blood.” He scooted to the side enough to wrap a hand around Blaine's straining cock and pumped hard and fast. Blaine's body went rigid under him.

“Oh, God, no Kurt, I'm too close, I'm going to come . . .” Blaine moaned.

“Yes you are.” Kurt made it a command and always obedient Blaine was only too happy to comply.
