Kurt's heart missed a beat and his mouth went dry as he slowly made his way over to the bed. Blaine lifted his head as he heard Kurt's footsteps, and Kurt couldn't help but react to his bound sub. He walked faster, not wanting to make him wait; who knew how long he had been lying here already. God - what had he been thinking? What if Kurt had stayed longer with Elliot? What if he had decided to go for coffee or groceries on the way back? He didn't know how to react to this. Blaine couldn't do something like this, something that dangerous. He thought about untying and punishing him to really drive that point home, and then establishing a new rule forbidding him access to their toys without Kurt there. But on the other hand...

When he arrived at the bed, he sat down and put one hand on Blaine's chest. Blaine had been tense, but Kurt could feel the tension dissolve under his fingers; he also saw the light sheen of sweat on Blaine's hairline. It couldn't have been easy for Blaine to do this, and despite everything, Kurt certainly appreciated the gesture. He also had about a million ideas about what to do to him. But first, he had to be sure.

He quickly took the blindfold and the gag off, keeping one hand on Blaine's chest as much as he could. When Blaine opened his eyes, he smiled brightly.

"Hello, Sir"

"What's this, pet?" Kurt asked. Neither the Dom voice nor the stern expression were a conscious decision, but came naturally as a reaction to Blaine and also because he still wasn't sure how to feel about this. He had the impression the smile grew even brighter.

Then it faltered, and Blaine cast his eyes down.

"I'm not trying to force your hand, Sir. I just thought I'd try to show you how much I trust you."

"Is that the only thing you want?"

It took Blaine a moment to understand, but when he did, he smiled again.

"We've been talking about this, Sir, and I told you I wanted it. And I've only been planning this since yesterday, but...well, sometimes it's seemed like a very long time. I'm a little scared, but mostly excited."

Kurt was mostly convinced, and moreover, he was sure that if he refused Blaine now, it could do a lot of harm. Blaine was offering something big, and it was Kurt's time to take what was given.

He smiled, determined not to show any displeasure. "One thing you have to tell me though, before we start." He gestured all over Blaine's body. "How on earth did you pull this off?"

Blaine laughed. "Chandler helped me. And, because I know you worry - Master Elliot was in on it. He texted Chandler when you left, and he left just early enough not to run into you on the stairs. I was alone for maybe three minutes. Also, if one of us doesn't text him within the next five minutes, he'll come back. I gave him a key."

Kurt was impressed and relieved. Blaine hadn't been quite as reckless as he had thought. He wouldn't punish him, but he'd probably still deny him access to the toys."It's a good thing I didn't get carried away, or else he would have walked in on us in the middle of the scene."

"He was probably hoping for that."

Kurt wrote a quick text to Chandler, thanking him and Elliot and telling him he would be taking over now. Then he ran a teasing hand over Blaine's body. Blaine was completely relaxed now and had closed his eyes. He smiled at Kurt's touch.

"I think," Kurt said, "I want you a little differently. It's time you discovered what this bed can do."

He stood up and released a flap in the wooden canopy of the bed. Like oxygen masks on a plane, two leather-padded stirrups tumbled down.

"They move on rails," Kurt explained. "If I put them on your ankles or knees, I can practically move your legs wherever I want them."

He freed Blaine's legs from their bonds and let him move them for a bit while he went to get a bottle of water and helped Blaine drink; even if he hadn't been wearing the gag for long, his mouth must be dry.

Then he placed Blaine's knees in the stirrups and pulled them up, forward and apart until Blaine was completely exposed, his ass just a little elevated from the bed and his legs pulled back and apart, everything wide open for Kurt to look at or to touch.

Blaine looked at himself and blushed, but his cock began to swell and his head fell back as he closed his eyes and moaned.

"You tell me the minute anything becomes numb or even just uncomfortable," Kurt said, and Blaine nodded. "You'll be getting the blindfold again, but not the gag. You may make sounds, but not speak except to safeword. I'll also give you headphones with music playing on low. You can't see or hear me, and occasionally I may even stop touching you, but I won't leave this room. I'll be here the whole time. Do you understand?"

Blaine nodded, then caught himself and said, "Yes, Sir."

"And if you get scared or uncomfortable and want to stop, even just for a moment?"

Blaine cleared his throat. "I'll safeword. Red for stop, yellow for a break," he said quietly.

Kurt nodded, took a deep breath, and started.

He gently kissed Blaine, put the blindfold back on him and took a step back to admire him. He got him headphones and put on a playlist of calming songs he sometimes put on when he had trouble falling asleep. He smiled. He doubted very much Blaine would fall asleep; after a while, he would probably not even notice the music anymore.

Kurt hesitated a little. He rarely used a Wartenberg Wheel, because he always felt a little stupid sitting there with this small toy like he was cutting pizza or something; furthermore, he used a similar instrument at work which held the possibility of a lot of awkwardness.

But he took it out now. No one was here, and Blaine was hardly in a position to judge him, even if he were able to see what he was doing. And he was indeed laid out there like a canvas to do with as he would, to leave his mark on, which made the comparison to work more appealing than awkward.

He waited a bit, not moving, barely breathing, just to let Blaine feel the anticipation. Not too long, though; he knew this was hard for Blaine, and he wanted to ease him into it a little. Besides, there were better things he could do.

So he sat down on the bed and felt Blaine relax again as the mattress moved under his weight. Without warning, he touched the wheel to the inside of Blaine's arm, so light the spikes would tickle more than prick. He heard Blaine's sharp intake of breath, and then rolled the wheel down his arm, keeping the pressure light until he reached his wrist.

When he took the wheel away, he could feel Blaine exhale and relax, but immediately tense again when Kurt put the wheel on his other arm. He pressed harder this time, not hard enough to break skin, but still so hard it hurt more than it tickled. Blaine gasped, and then moaned when Kurt followed the trail of the wheel with a featherlight touch of his fingers.

Kurt kept touching Blaine with the wheel, sometimes pressing hard, sometimes just tickling, sometimes rolling it on his skin for a while, sometimes just touching it somewhere and taking it away the next moment. He didn't keep any system to where he was touching him, if he used the wheel or his fingers, or how hard he pressed with either. There was no way for Blaine to figure out what he was doing, and he reacted in the most delicious ways.

Not being able to hear himself seemed to have taken away all of his inhibitions in that area, and Kurt was really glad he had foregone the gag.

Blaine gasped and moaned, whimpered and pleaded wordlessly. He clenched and unclenched his hands, and whenever the wheel came near an area he felt he didn't want it, his whole body tensed, only to relax again when the wheel wandered further. When Kurt rolled the wheel not too gently over one nipple and lavished the other with his tongue, Blaine arched from the bed as much as he could and cried out, turning his head from side to side as if his body wasn't able to understand how he could feel two such different sensations at the same time.

Kurt took great pleasure in this. At one point, he had to leave his sub lying there for a minute to at least open his pants; they had strained too much for him to keep sitting the way he had. He stood up to do it and watched Blaine gradually relax his body and calm his breath, and then, without warning, rolled the wheel gently over Blaine's exposed perineum.

Blaine thrashed in his bonds, his ragged breaths nearly obscuring his muttered curses. Kurt slapped his ass hard as a punishment for speaking, and while Blaine was occupied trying to get over these different sensations, he quickly lubed up his fingers. He pushed one finger into Blaine, then two, and started gently finger-fucking him for a while without doing anything else. He let Blaine enjoy the familiar sensation, watched how his cock started leaking precome on his belly, and listened to Blaine's moans. He decided to be merciful.

"You can come, pet," he said. "Whenever you're ready."

Then he touched the wheel to Blaine's cock.

Blaine shouted as his whole body tensed, tendons standing out like cords on his arms and neck as he threw back his head and came violently.

Kurt stood up, quickly got rid of the rest of his clothes, and then lubed himself up and pushed into Blaine's ass without giving him any chance to come down from his orgasm. Blaine hissed from oversensitivity, but pushed back as far as he could, welcoming Kurt in. Kurt groaned and lost himself in the feeling of fucking his completely bound, helpless sub, whose spent cock still twitched eagerly when Kurt hit Blaine's prostate. Which he did as much as he could, of course, as it also elicited the most delightful sounds from Blaine.

But as much as loved torturing Blaine that way, soon Kurt's body took completely over, and he fucked Blaine harder, kneeling between his legs and holding his hips for better leverage. Soon he came, toes curling into the mattress, to the sounds of Blaine's constant moans and whimpers. He pulled out, still panting, and finally released Blaine from his bonds. He massaged Blaine's legs for a bit, but he didn't worry; they had a good color, and when he asked Blaine if everything was fine, he nodded and smiled. He was asleep before Kurt was finished cleaning them up, which he did haphazardly and quickly and then went back to bed and pulled Blaine into his arms. Blaine mumbled and smiled and nuzzled into him, Kurt closed his eyes.

"I love you, and you make everything better," he whispered.
