Blaine blew softly against Kurt's stomach, raising the tiny hairs on his skin. The other boy shivered, then let out a giggle.

"Tickles," he said when Blaine looked up at him.

Blaine grinned devilishly before reaching down and tickling the back of Kurt's knees. Kurt squealed, curling his legs up to his chest and kicking his feet when Blaine tried to do it again. Blaine laughed with him, moving up the bed on his knees for a better vantage to poke and prod and wiggle his fingers at Kurt's sides and underarms and neck and inner elbows until they were both crying with laughter and collapsing on top of each other.

Kurt rolled them over so he was the one leaning over his best friend, both of his hands pinning Blaine to the bed. "Just for that, I'm going to nominate you for our sensory deprivation lesson tomorrow."

Blaine opened his mouth to complain, but really he didn't mind. It had been a while since he'd been teased that way.

Suddenly he was very eager for class the next day.

----

"All right, I need a volunteer," Mr. Ramstein called out the next day. It was only second period, so everyone was still waking up, coffee was just starting to kick in. Mr. Ramstein's classroom was on the first floor with a wall of windows that faced the courtyard. There was a layer of fog over the grass, hiding the buildings on the other side and cloaking two meandering professors as if they were phantom robes.

Kurt was quick to grab Blaine's hand and raise it up for him. His friend blinked blearily at him. He'd been running late that morning -the boys had invaded their room and they hadn't gone to bed until very late- and he had to skip his morning coffee run.

"Kurt?" their teacher questioned.

Kurt looked over at him with a wide grin. "Blaine volunteers, sir!"

"Ah, excellent. Blaine, if you will," he gestured towards the front of the class where a demonstration table was set-up. It wasn't as big a room as some of their lecture halls with stadium seating. This one only held twenty student desks, all facing a dry erase board, as banal as any high school.

With a side look at Kurt, Blaine stood up, ruffling his hair a little to try to wake himself up. His professor welcomed him at the front of the class with a cheery grin.

"Since you volunteered, you get to choose the order. What would you like?"

Blaine considered for a moment before answering, "Sight. Speech. Sound. Touch."

"Very well then," Mr. Ramstein replied while digging through a drawer in his desk. When he straightened back up, he had a blindfold in his hand. Blaine took a deep breath before he was turned around and his eyes covered.

"Now," his professor continued, his attention directed to the class at large. "I need four boys for each phase. Who would like to start?"

Blaine heard with minute detail as his peers shuffled in their seats, jackets jangling against chairs, fingers tapping against desks, murmurs not-so-whispered between friends. His vision was blocked -just a sea of black with red at the edges from the sunlight- and already his other senses were on high alert trying to make up for his blindness.

It was David who was eventually picked amongst the sea of raised hands. Blaine couldn't help but smile, to himself and to his friend. They hadn't seen each other in a while (intimately, that is) and it would be nice to re-familiarize themselves with each other.

David made quick work of his clothes, being careful to drape his jacket over a nearby chair so it wouldn't get wrinkled on the metal demonstration table.

Blaine shivered as his skin became exposed to the cool air of the room. There might even have been part of him that shivered from the idea of being so exposed. He'd been at the academy for three years and had shared his body with many of its members, but every now and again -like when he was vulnerable- his innocent side came out and he was suddenly aware again of having everyone's undivided attention.

He crossed his arms in front of himself self-consciously.

"Hey now," David soothed softly. "None of that." He reached out with gentle hands and helped Blaine get up onto the table behind him. He stopped him from lying down all the way, though, with a strong hand on the back of Blaine's neck. "Let's start slow, okay?" David suggested.

Blaine nodded, smiling when his fellow Warbler interlaced the fingers of two of their hands. It helped to ground him when his lack of sight threatened to let him loose in the abyss.

David continued from there, only using his other free hand to trail the feather Mr. Ramstein provided up and over Blaine's body. Blaine tried his hardest not to laugh as the barely-there down of the feather awoke all his nerves from toe to hip to shoulder, but he couldn't suppress a laugh when David playfully dug it into the sensitive spot of his neck. Blaine could practically feel Kurt's smug grin from across the room.

Shortly after that, when Blaine was shivering for yet another reason entirely, Mr. Ramstein signaled David to finish and for the next volunteer to come forth for stage two.

Speech.

Blaine waited, his ears pricked, to sense when his next classmate would approach with a gag. He heard Nick's named called and soon thereafter his mouth was being goaded open to accept a ball gag. He stretched his jaw open as wide as he could, adjusting to the size of the ball shifting it around with his tongue until it settled in place and Nick secured it behind his head.

The feel wasn't altogether unpleasant. He'd been gagged many times before by a variety of textures and styles and had become accustomed to the heavy weight on his tongue, the pressure on his teeth, the burn in his jaw after a while.

He didn't mind losing his speech that much, in the same way he enjoyed the surprise that came with blindness, he enjoyed the trust that came with being mute. He couldn't call out for anything -positive or negative- and so he always placed quite a bit of trust in his companion to know what his limits were.

Nick trailed his fingers through Blaine's hair after closing the fastenings on the gag. "Beautiful boy," he whispered in his ear. The sub in Blaine, who had been Dominated by Nick more than once, preened.

Nick continued to touch, deep and sensual, digging into the knots in Blaine's back and loosening his muscles until he was drooping onto the table. Nick let him lay down, a pool of liquid under his hands, and continued to knead at his thighs and calves. He took one of Blaine's arms in his hands and pressed endless circles into the flesh of his palm, following the vein in his forearm up to his tender elbow and further still to his toned bicep.

Blaine moaned, one of the few sounds he could still make, though it came out deeper and more muffled from his throat. He reached out and chased one of Nick's hands with his own, begging for more without words. Unlike their Body Worship class, they were allowed to interact for sensory deprivation. In losing one sense, they gained access to others.

Their hands danced together for a minute, Nick's under Blaine's as he continued to massage the prone boy. Nick pumped Blaine's cock a few times as well, relieving some of the pressure that was building up inside him. He stopped soon after, though, signaled again by their professor.

Blaine resisted groaning at the loss of contact. He knew what was next and things were about to amp up tenfold for him.

Sebastian was the one to place the noise-cancelling headphones over his head. He was kind enough to pause to give Blaine time to process the change.

For Blaine, he had just gone from being hyper aware of every little noise that anyone was making to suddenly hearing nothing but a faint hum of unnatural silence. There was a moment of panic as his body started to enter fight-or-flight mode. With no sight, no voice, and no hearing he was helpless against the whims of others.

The hairs on his skin prickled in awareness. He could suddenly feel the warmth of the sun through the windows in contrast to the flow of air from the vents above. He shivered and flexed all at once and that was when Sebastian finally made contact.

Blaine felt a solid hand wrap around his arm and he immediately reached back to wrap his own hand around Sebastian. He took a few deep, calming breaths, as Sebastian stroked a thumb back and forth across his inner arm.

And when Blaine's heartbeat finally returned to normal, and only then, Sebastian released his grip and let his hand slip away until Blaine was on his own again.

Not for long.

He felt a new heat near his ankle. More than sunlight. More than a hot breath. It trailed up his leg and over his stomach until suddenly a drop of something landed against his flexed abdomen.

Blaine flinched, his entire body reacting to the new stimuli.

It was hot at first, a pinprick in the darkness, but then quickly mellowed. Blaine flexed his stomach again to see what the liquid would do, but it was no longer a liquid. It sat on top of his skin like a protective shield, and diluted the sting of the next drop.

Wax.

Sebastian traced his body with the little firey drops. After getting Blaine used to the feel on his stomach, he shifted up to coat each nipple, then down again to dress his thighs, his balls, his cock.

Blaine arched, his back leaving the table with each lick of fire against his sensitive skin.

By now his senses were overloading, each nerve overexcited by the attention it was getting. And Sebastian was laving attention on his most sensitive spots so that he was mewling and salivating in need.

The torment suddenly stopped.

Blaine clenched his hands into fists at his sides. He wanted to reach out for more, but he knew that Sebastian's turn was over and there was no point.

His reaching hand was grasped by another. Skin smooth against his palm. He recognized him immediately.

Kurt.

His aching need only increased knowing who would finish him off. He shifted this way and that trying to relieve the itch, but Kurt took hold of both his hands and raised them over his head.

While his best friend secured him to the table, both hands together above him and each leg spread below him, someone else used a wet cloth to clean the cooled wax from his body.

He squirmed as his even more sensitive skin was touched and tried to make another sound of want deep in his throat.

He felt a hand against his chest. Strong. Firm. Grounding.

Kurt.

The other boy couldn't comfort him with words anymore, so he was doing the next best thing. Blaine let his body relax in gratitude.

Kurt started slowly at first, as all the boys had before him, giving Blaine time to adjust to having lost yet another sense. Touch. Blaine was now completely and utterly at the mercy of his best friend. There were worse things, he thought to himself.

After trailing his fingertips down Blaine's cheek and neck and chest and cock, Kurt disappeared for a second only to return with a cube of ice.

Blaine felt the cold like a shock against his ankle. His body jerked so violently in reaction that all his limbs pulled against his restraints. The cold was an awful contrast to the heat from Sebastian and to the heat that was burning low and steady inside of him.

It trailed up his leg and he shivered when Kurt pressed it solidly against his inner thigh. His cock twitched ans his balls tightened as if to escape the new unwelcome sensation. But then there was something else. A breath. Kurt blew softly along the line of the ice cube, raising hairs and unbelievable sensation along Blaine's leg.

Blaine shuddered, his mouth slackening around his gag. There were no words.

Kurt kept going, tracing the prominent vein on the underside of Blaine's cock and then letting the ice settle in his navel. All the while he'd blow dry the new wetness until Blaine was straining towards him, silently begging for more.

Kurt twirled his tongue briefly in the water that had pooled in Blaine's bellybutton. Then, he acquired a new cube, and Blaine twisted beneath him as he charted a path across the dark-haired boy's body.

He stopped at one nipple, holding the ice in place until Blaine was sure his skin would freeze, and then pulling away just at the breaking point to blow hot and humid against the hardened nub. He did it again on the other, then on Blaine's neck, licking up the trail of water with his tongue and heating Blaine's cool skin with his own mouth.

When Blaine couldn't take it any longer, his wrists red from pulling against the cuffs so hard, his body a molten mess of hot and cold and incoherent grunts escaping past his gag, Kurt helped him find release with an enveloping mouth around his cock.

"Class dismissed."
