A/N: Written for the prompt 'BDSM'. Rated M for bondage, heat and ice play. Future-fic. AU. Dom!Kurt Sub!Sebastian. Sebastian goes to Scandals looking to get laid and runs into an innocent looking man he can't wait to get on his knees. Things change drastically once Sebastian gets him home.

Kurt watched the white wax melt around the lit wick, the golden flame flickering every time Kurt breathed. The melting process fascinated him, his gaze fixated on a single drop that formed and grew as more hot liquid wax joined it. Then, with a pregnant pause and a slight bounce, it broke free and fell. Sebastian hissed as the scorching hot droplet made contact with his skin, sparking off a fantastic array of sensations – a piercing moment of intense heat which bled away almost immediately to an erotic crackle as the hot liquid cooled and hardened. Another drip joined it, then another, wax dropping like tiny explosions and igniting every nerve in Sebastian's body. With a wicked giggle, Kurt poured a line of hot wax down Sebastian's chest, threatening to travel lower, to more sensitive, delicate areas of skin. Sebastian's green eyes went wide with fear. He tugged on the leather restraints that kept him tethered to the bed frame, clenching his teeth in anticipation of the pain.

"Don't worry," Kurt purred. "I'm not sure you're ready for that yet…but soon."

It sounded like a threat and a promise. Secured by a restrictive metal cock ring, Sebastian's cock ached.

Kurt grinned, a devilish curl of his tempting pink lips that accentuated the mischief shining in his blue-grey eyes. He crouched over Sebastian's body like a cat; but not a sweet, docile house cat. More like a wild and untamed jungle predator, and Sebastian, hands locked above his head in thick, leather cuffs chained to the wooden slats of his headboard, felt an awful lot like prey – weak, vulnerable, helpless.

Another drop hit Sebastian's skin, dangerously close to his nipple, and he bucked up. Kurt's grin slipped immediately to a terrifying frown. He put a hand to Sebastian's chest, right in the center of a patch of thick wax, and pushed down hard. Sebastian groaned, his skin stinging beneath Kurt's hand. He fell back hard on the mattress.

"Bad dog!" Kurt growled, bearing perfect, white teeth. "Now sit! And stay…"

Sebastian watched Kurt sit up and stare down at him with blank eyes, but he could see Kurt's mind working. Kurt sat like a statue, his body wrapped in sinful black vinyl, such a stark contrast from the outfit he wore when Sebastian approached him at Scandals.

Bored, horny, and alone, Sebastian had gone out to the bar, prowling for someone to wrap their mouth around his dick. He stumbled on Kurt, sitting on a barstool, nursing a Shirley Temple. Sebastian usually went for the muscular, body builder type; guys who dressed in jeans and t-shirts, and generally had an IQ to match their shoe size. Kurt' s long, lean body draped in head to toe Alexander McQueen and straddling the boundary between masculine and feminine mystique definitely did not fit Sebastian's image of a perfect one-night stand. But pickings were slim, and Kurt, with a demure blush rising to his porcelain cheeks and his wide, innocent blue eyes made Sebastian's blood boil. He salivated at the thought of getting this frightened looking man on his knees.

How did the tables turn so drastically?

The wax travelled down the candle and settled on Kurt's hand, forming drips and rivers that hardened almost on contact, but Kurt didn't even flinch. Sebastian swallowed hard as Kurt's eyes swept over him. Sebastian was used to lovers looking at him. Usually he preened under the appreciative gaze of someone he intended on fucking, but for some reason this was different. He felt exposed. He gritted his teeth, desperate to regain some control.

"So, is that all you've got, princess?" Sebastian murmured, recapturing his cocky grin.

Kurt took a moment to respond, tilting his head curiously.

"Princess?" he repeated. Then he laughed. "Is that what you see when you look at me?"

Sebastian hadn't given it any thought. 'Princess' was just one of his patented insults.

"No," he said seriously. "It's not."

Kurt extinguished the flame of the candle with his fingers, setting the taper aside. He crawled slowly over Sebastian's body, inching over his wax covered chest until he looked deep into his eyes. Sebastian could smell Kurt's sweet vanilla scent. It seemed to cover every inch of him. Kurt bit his lip. Sebastian watched the teeth work over the delicate skin. He wanted those lips on his skin. He burned to find out if Kurt tasted like vanilla, too.

"Then, what do you see?" Kurt asked, mouth hovering dangerously close to Sebastian's eager lips. "What do you see when you look at me?"

Sebastian waited a beat, not wanting to rush into an answer.

"I think you're stronger than you appear," he started.

Kurt sat back, his brow furrowed.

"Do I look weak?" he asked.

"You…you did…" Sebastian stammered, "you know, before…at Scandals."

"Hmm," Kurt hummed as he nodded, considering this. "What else?"

"I think…I think you're sexy…"

Kurt chuckled.

"Sexy?" He sounded almost disbelieving as he repeated the word. "You think I'm sexy?"

Sebastian saw Kurt's walls, carefully constructed around vinyl catsuits and leather cuffs, come down a little. Kurt's cold eyes softened.

"Yeah." Sebastian's lips twisted into a more genuine smile than his signature cocky grin. "In fact, I think this whole BDSM thing you got going here…super-hot."

Kurt nodded again, reaching beside him to a bowl that Sebastian had noticed only briefly before, but had no idea what Kurt had put in it. He saw Kurt pull out a single cube of ice and slip it into his mouth.

"Go on," Kurt said around the ice, reaching for another piece. Sebastian's eyes followed Kurt's hands as he placed another piece in his mouth.

"I think…you seem really interesting," Sebastian continued, finding it hard to talk while Kurt moved the ice around his mouth, licking over the blocks with his delicious looking tongue. "I would really like to get to know you."

"Know me, huh?" Kurt mumbled. He started biting down on the ice, cracking the blocks into pieces and swallowing them, reaching into the bowl for more. "Well, I'll tell you what…let me finish and maybe I'll let you take me out for coffee."

Sebastian smirked. He thought over his situation for the moment. Tied up with Kurt on top of him; he figured sex was pretty much guaranteed.

"I think I can do that," he said, relaxing into the mattress and waiting for whatever Kurt had planned.

Kurt's sudden and menacing grin wiped the smirk off Sebastian's face.

"If that's what you think…"

Kurt moved quickly, crawling back down to Sebastian's legs and sinking his mouth over his straining erection. The intense cold of ice still melting in Kurt's mouth turned ache into agony. Sebastian screwed up his face, his eyes squeezing shut. He bit hard on the inside of his cheek to keep from screaming.

Kurt raked a hand down Sebastian's chest, nails tearing through the wax and scoring marks over Sebastian's sore skin.

Sebastian's screaming couldn't be helped this time.

Kurt pulled off Sebastian's cock and laughed.

"If that's what you think, then you're in for a long night."
