Bind You Down Just for You

Dr. Blaine Anderson was extremely upset these days. There was an 8 years old boy who just came to his diagnosing room 3 days, an Asian black eyes with slim limbs, which reminded him of one of his old high school classmates. However, a tumor was discovered by the MR image in the pons which was a restricted zone for surgery, so he had to tell the parents that there was no chance he could be fully cured. The crying sound and desperate eyes haunted in his mind for days, leaving him with the feeling of powerless and inability. And he found there was no chance he could talked that to Kurt, who was over-occupied with those interns, one of them, Chandler or something else, keep texting Kurt asking those stupid questions, "What is the most common complication of semicircular decompression？", really? Can't you look up in the books by yourself? But Kurt seemed more than happy to answer those questions. Blaine's volcano finally exploded after he broke the plate in the Christmas morning.

"What happened, honey?" Heard the sound, Kurt ran to him from bedroom.

"Perfect!" Blaine roared to himself, "Now I have no breakfast!" He squatted down to pick up the scattered debris and scrambled eggs.

"Sweetheart, are you hurt?" Kurt showed concern.

"No, stay there, Kurt, you gotta stand on them!" Blaine was still annoyed. The gentleness of Kurt which he used to find sweet seemed bothersome now. He didn't deserved being gentle now.

"Do you need me to cook one more egg for you?"

"No! I can do it. Just go back to sleep!" Blaine shouted.

"Blaine…what happened? Why are you acting so strange?"

"Nothing!" Blaine's voice went down a little. "Just, leave me alone."

Kurt raised his eyebrows, Blaine thought he was going to say something, but he just turned back to the bedroom.

Great! Blaine Anderson, now you just drove away the man you love the most! He is going to abandon you now!

Blaine cupped his face and sat back to the ground, feeling so frustrated and helpless.

After a while, he heard footsteps coming to him, he looked through his fingers: black boots. Then he looked up and totally stunned by the owner of the boots.

Kurt was wearing a black unitard and skin-tight black leather trousers which depict the perfect body line of his long legs. He looked so sexy that Blaine felt the reaction in his pants immediately.

"What…what is that? Kurt? Some sort of role play?"

"No," Kurt smirked, looked so different from the normal sweet Kurt. "This is real." He stride across the debris, picked Blaine up, took him into the bedroom.

"What are you doing? Kurt?" Blaine chuckled, "Put me down!"

Kurt threw Blaine to the bed, and cuffed him to the bed posts in no time.

"What is this about? Are you going to punish me for shouting at you?"

"No," Kurt put his face near Blaine so close that Blaine could sense his breath, petting Blaine's cheek, "It's not a punishment, it's a rescue."

"Rescue of what?"

"Rescue you from your self-destruction."

"I'm not self-destructive. Besides, how could this saving me from that?"

"Have you ever heard of BDSM? Do you know why there are people love it?" Kurt tilted his head.

"Of course, I got an 'A' of my Psychology!" Blaine showed his expression of proud, "Endorphins and enkephalins will be secreted by our brain after our body suffering from pain, like some kind of compensate of us being brave."

Kurt grinned, "That's right, my model student. But do you know what do you need if you were in a BDSM relationship?"

"Me?" Blaine choked a little, haven't thought about that before, "To control, I guess, I'm a surgeon, right? Surgeons always want to control everything."

"Exactly…" Kurt paused a while for purpose, "the opposite!" he got amused by the shocking look in Blaine's face. "You need to give up control. And you need a little pain."

Blaine wanted to deny, but somehow deep in his heart, he knew Kurt was right.

"You are tired of taking control, Blaine, in real life." Kurt seemed pretty certain about what he was saying, "You want to release. In addition, you have a trend of never forgiving yourself. You need some kind of pain to help you to forgive yourself."

Blaine completely muted, thinking of what Kurt said. "But isn't it common? Won't you feel great after pain? Like pouring hydrogen peroxide to your wound, you will feel pain at first, but if you endure that, you will feel the electricity of pleasure afterwards?"

Kurt burst into laughter and lasted for a long time.

"What?!" Blaine got miffed.

"You are such a born sub!" Kurt still couldn't stop laughing, "No, honey, I do not feel that way! Pain is only pain for me, but I think it is different for you." He turned into a serious face, "Do you believe in me?"

"Yes, of course. Kurt."

Hearing that, Kurt leaned, kissed him gently, then he pulled him away a little, looking into his eyes as if to search for the deepest desire of his heart. "Will you give up yourself to me? Would you like to serve me?"

"Y…Yes…" Blaine bit his lower lip hardly, he could hear his own heart beating now, anticipating what will happen next, although admitting the thought that he want to serve Kurt had already turned him on which surprised himself a bit.

"Stop biting your lip." Kurt ordered. Blaine shivered at that. "That is my property now, no one can damage it, even yourself. Do you understand?"

Blaine nodded.

"Good boy." Kurt praised, "I see you can obey now, I think I can uncuff you." As said, he released Blaine, and immediately, "Get off the bed and, on your knees."

Blaine quickly did what he was told, kneeled beside the bed.

"So submissive, you really turn me on," Kurt grinned, "Hands behind back…Great." And then he cuffed Blaine's wrists together. "Look up, Blaine, one more important thing, choose a safe word. Do you know the meaning of it and how to use it?"

"Yes."

"Recite it."

"If I feel uncomfortable about anything, I can say it. You will know and stop doing it."

Kurt nodded satisfactorily, "Someone did do the homework. Now pick one."

The word just hit his mind. "Blackbird."

Kurt raised one of his eyebrows, but he didn't negated it. "That is… fine. Blackbird it is, remember, anything, anytime, if you feel you can't stand anymore, say it, OK?"

"Yes."

"And from now on, you are deprived of speaking, the safe word, of course, is an exception, but otherwise, you are not allowed to talk, if you disobey, I will punish you afterwards. Nod if you understand." After Blaine nodded, Kurt continued, "Now suck me."

Blaine looked up, confusing. Kurt was still fully dressed, but his hands were cuffed behind, how could he do that?

"Use your beautiful mouth." Kurt seemed to know what he was thinking about.

Blaine sighed, kneeled up a little, and used his teeth and tongue to find the zipper. The zipper was easy, but when it came to the button, it really cost him a lot of time, he hoped that Kurt wouldn't get exhausted through waiting. After the trousers were stripped down, Blaine found Kurt was not wearing any underwear and he found there was no need for him to worry about，Kurt's cock was already rock hard as himself. He took it into his mouth and happily heard Kurt moan.

"You are really good at it." Kurt then hold Blaine's head behind, took the control back, forcing him to stay still, thrusting into his mouth.

Blaine kneeled, hands cuffed and mouth opened being fucked. He felt so helpless that being used with no method to escape, yet he felt so relieved, no more decisions need to make, no more effort need to make, just let Kurt to take control of him. The thrust became stronger and deeper, which caused Blaine choked a little since Kurt's was so big and heavy, but he tried to relax and adjusted to Kurt's movement. When he could feel the constriction of the tip of it, he made to swallow every drop of Kurt's cum.

Kurt let out a sigh of pleasure, "You are an expert. Now you are rewarded with some prize."

Blaine's eyes widen, pleaded with his puppy eyes.

Kurt giggled, "You want to fuck me?"

Blaine nodded fiercely.

Kurt laughed, "Later, maybe, but not today. You have to make bigger effort to earn it," He noticed the frustration look of Blaine, comforted, "you will like this one though, I promise." He turned to the closet, opened the lowest drawer, took an eye patch out and applied it to Blaine.

Now it was completely dark for him. He could sense Kurt uncuff him and lift him up to the bed. He was placed with his arms on his body sides and his legs doubled up and wide opened. Then his wrists were bound to his ankle of each side with some soft cloth, or leather maybe. Kurt adjusted several times to make he felt comfortable, then Kurt stopped a while to admire what he had create, a fixed exposed man, blinded, light tan skin, firm and smooth, muscular limbs, all tied up for him. He smiled, leaned forward to lick the nipple, seeing Blaine biting his lip, trying to avoid a sound. Kurt said, "You are biting your lip again, you are gonna get punished later. You can moan, that is my fun part, don't rip it from me." Blaine opened his mouth and started to moan heavily as Kurt scrubbed and squeezed his other nipple at the same time. Then all in a sudden, a clip was biting his nipple, he screamed, it was so painful he thought he could bear no more.

"Shh…" Kurt licked his other nipple, giving him the feeling of pleasure and pain in the same time. "Stay with me, babe, I'm so proud of you. Stand the pain for me, will you?"

Blaine nodded, he gasped, letting the body get used to it, and then the pain gradually faded away.

Seeing Blaine's breathe back to normal, Kurt smiled, "I love you so much, you work so hard for me." He latched Blaine's penis and started sucking it the same time putting another clip on the other nipple of Blaine. Blaine screamed loudly.

Kurt hesitated a little, he looked up to Blaine's face, checking, "Are you OK? Is it too much?" Blaine shook his head. "Are you sure? Do you need your safe word?"

Blaine shook again, he didn't want to stop. The torture of his nipples became a kind of sweet pain mixed with pleasure.

Kurt relieved, he put some press on the clipped nipples, rubbing them in circles. Blaine grasped, feeling he was going to come out simply because of the touches on his chest.

Kurt pecked all over his chest to the navel, murmuring "My beautiful slave, so irresistible, all opened up for me." He opened the bottle of lube, poured a great amount of it on his fingers and applied to the back entrance of Blaine.

Blaine inhaled when Kurt's finger was in his body, arched his waist to get more from Kurt.

"Down, boy." Kurt pushed his abdomens with the other hand, and kept stroke the finger in Blaine's tunnel. "It is not about you, baby, it is about me. You are doing this just for me. You cannot chase your own happiness now. And you are not allowed to cum till I say so."

Blaine felt incredible aroused with the words that he was no more than a tool to make Kurt feel happy, he was there, all opened up, ready for his master to use him. The pre-cum had covered all the tip of his cock without Kurt even touched it.

After three fingers in his body, Blaine was fully stretched. Then all in a sudden, Kurt pulled out all his fingers. And the emptiness attacked Blaine. He was so eager to be filled up, both his body and his mind. He thought Kurt was going to get into him right now. However, he was left untouched. He wanted to plead, he wanted to beg, but the rules came into his mind, he could not talk and he could not see anything. All he could do was to listen and sense. But there was nothing. In the dark, he had no choice but wait. He waited for so long that there was one moment that he thought Kurt had already left, leaving him all tied up and completely helpless, maybe Kurt was really angry and wanted to punish him in that way. His tense body which was waiting for sex released a little of thinking of that, but the next second, he was pieced through. Kurt went all the way down to the deepest part of his body and soul, filled them. He was in the brink of organism, he knew he wasn't allowed to, but he couldn't help begging, "Please…Kurt…I need to…"

"No, hold it, boy, not before me." Kurt continued to slam into Blaine's body, slow but deep and firm, he adjusted the position a bit so he could hit the prostate every time. The boy underneath was sweating and blushing, his cock was shivering with desire for touching. So Kurt hold the erection and slowly stroked it with its own pre-cum, then he speeded up. Blaine moaned loudly when Kurt's long fingers touched him, it was so big and warm, he had to cum no matter what. Then to his surprise, the clips on his nipples were pulled away at the same time, the pain and pleasure of liberate of his sensitive part came all the way through his spine and to the brain, he cum with a long and loud groan. He went completely blank in his mind. It was a place he had never been to. All his concern and worries flew away with the breeze. He could feel Kurt stroked a few more strikes and exploded in his body.

Kurt paralyzed on his lover's body, with his cock still in. It took a few minutes for both of them to catch their breath. Kurt pulled out, fondled Blaine's limbs and released the bondage, took off the patch, and asked, "You have broken several rules, honey, we may discuss that later. But before that, how do you feel? Do you like your Christmas present?"

Blaine enjoyed the gentle massage Kurt giving to his sore ankles and wrists, still sunk in the aftershock of the severe sex, "Umm…Best present ever."

"That would be great." Kurt chuckled, "Knew you would like it." He lied down and they cuddled.

"More than like." Blaine grinned, turned side to kiss the neck of Kurt, "How I admire you, my Mater. When did you start to prepare these?" He pointed to those implements they used.

"Oh…for a long time." Kurt giggled, playing the curls of his hairy boyfriend, "I noticed you had been upset for days, and so I figured out this could be a method to solve it. Did I?"

"Oh, yes, you did solve it. Thank you, darling." Blaine smiled, "It's just…I didn't know you had this potential before, all the…orders…they were so hot."

"Nor did I know before," Kurt smile a bright and satisfied smile, kissing Blaine's front head, "But I can learn, and I will do anything, just for you!"

A/N：So…do you love it? Let me know what you think. Please.
