C is for CBT

Kurt hardly got any sleep last night; he was too nervous and excited about what the letter C would bring. He didn't know if it would be more pleasure-pain like A was or pain-pleasure like B was. But still he had a routine to follow so he climb out of bed hissing when his abused feet hit the tough carpet and slowly walked into the bathroom for his shower. Once he was done he went and made breakfast since he had no idea what today had in store and the machine form yesterday were clean he didn't have to clean up the playroom. He ate his breakfast quickly and then rushed to make Blaine's once that was done he walked into their bedroom gently woke his Master and gave him his breakfast and sunk to his knees.

"Are your feet feeling ok today pet? Do they hurt a lot?"

"Not really Master, not to bad I can walk around the house but I don't think I'll be running marathon anytime soon" Kurt said with a laugh.

The shorter man laughed as well "well that's good then pet, I'm all done you may take my tray away and then met me in the playroom its time for letter C"

Kurt stood grab the tray and took it into the kitchen and like always loaded the dishes into the dishwasher then made his way to the playroom where he could feel his stomach doing flip flop. Once he got their walked up to his Master and kneeled at his feet with his head down and waited instruction.

"pet, you have been very good these last couple of days, I know yesterday was tough on you, and I don't think today will be any easier" the submissive could feel his breathe get caught in his throat at those words Oh God its going to be pain-pleasure like yesterday, I don't know if I can take that its going to be too much Kurt thought.

"Now before you get all worried my love" Blaine said gently as he put his finger under Kurt's chin raising his head up so he looked him in the eye "I have a feeling you might enjoy what happens but its not going to be all pleasure there will be pain involved a lot of pain, but hopefully the good kind of pain."

"Now, boy" Kurt immediately recognized his Master Dom voice "Today letter is C and C stand for any guess?" Kurt shook his head no. "Well C stand for CBT, or cock and ball torture" the taller man couldn't help but gasp this was going to hurt like a son of a bitch and he knew it. "Stand" Blaine commanded walking over to the cabinets that lined one of the walls in their playroom, selecting the items he would need for the day.

As Kurt stood, he slowly brought his hands in front of himself, hiding his crotch from view; he could already feel the pain that would soon be inflicted onto his defenseless cock.

"Don't cover yourself up boy or I'll cuff your hands behind your back out of the way." Blaine said back still turned to his submissive.

Kurt gulped and nervously moved his hands back to hang at his sides. Evidently, the fear of this activity didn't put a damper on his arousal, as his cock continued to harden under the dominance of his Master.

Blaine was careful not to show his amusement at his boy's discomfort, as he walked back over to his pet instead he gave him an approving smile, focusing the hairless pubic area, Blaine loved to shave his slut it was the only real outward sign of Kurt's submission to his Master, only once in a while did he ask his boy to wear a collar.

"Now pet go stand over by the left wall," Blaine said as he pointed to the wall with the chains and cuffs hanging form it. Kurt followed instruction perfectly "raise your hands above your head and spread your legs" the curly haired man then start to lock the cuffs around his love's wrist and ankles holding him securely to the wall once Blaine felt Kurt was thoroughly fasten he leaned in, and nipped at Kurt's neck, then sucked, grazing his teeth against tender flesh. He moved his lips and tongue over the pulse point and nuzzled gently. He worked his way up, nipping at the boy's earlobe with his teeth; he flickered his tongue over it then blew a stream of cool air across it.

Kurt moaned and shivered, his body responding to the teasing attention. He could feel strong hands exploring his body, sliding over his pecks and down over the six-pack abs. All the while that wicked mouth played with the delicate skin at his neck, nipping tantalizingly. A hand finally settled on his smooth crotch, gently rolling his balls loosely in their sack.

Kurt moaned again in pleasure, squirming slightly and tilting his head to the side to allow the younger man more access to his neck. He was caught off guard when the hand that was gently fondling him started to pull downwards on his testicles; the pull was slow and insistent. The cuffs on Kurt's wrists wouldn't allow him to follow the pull downwards, which of course was the idea. He scrunched his eyes shut in pain but didn't cry out. The pressure was released and his ball sac relaxed, he gasped for air.

The warmth of the body pressed close to him receded and Kurt opened his eyes to see where Blaine had gone. He saw him collecting something from the bag he had taken out of their toy cabinet. In one hand the singer was holding a black leather blindfold; in the other he held a bundle of soft cord. He set the latter aside under the study of inquisitive blue eyes.

Blaine gently kissed Kurt on the forehead; causing the boy's eyes to instinctively flutter closed. The shorter man took advantage of that reaction and kissed each eyelid softly, and then he placed the blindfold over them and buckled it at the back of his head.

"Thank you, Master." Kurt spoke quietly, on impulse.

Blaine felt a surge of pride in his perfectly trained sub; he was a real treasure. He lightly kissed him on the lips, almost chastely. His hands sliding over defined pecks once more. He visually drank in the sight of this powerful man who was now chained and at his mercy. Blaine's cock pulsed in his slacks and he rubbed his erection through the fabric.

Blaine started to talk as he picked up the soft cord, "I'm going to bind your cock boy, tightly, make it so that you won't be able to cum, make your arousal hurt so well. Then I'm going to add a weight to a loop on the end so it's pulled downwards. It'll hurt but it'll feel so good you won't know if you want more or you want it to stop."

As his voice weaved the magic of the words, his hands doubled the cord and threaded it through itself to make a loop. He positioned it around the base of Kurt's cock and balls, to anchor it, and then he brought the cord to the front he held the hard shaft steady while the other hand wound the twin strands of cord tightly around the shaft. Keeping it snug, so there were no gaps between each pass of the binding.

He looked up to see that Kurt was biting his lower lip hard. He leaned forward and licked at the boy's earlobe, "let me hear you baby, I want to hear your pain and pleasure, want to hear you calling my name and begging me to stop and to keep going on, not knowing which way is up."

While he talked those talented hands continued to wind the cord tighter.

Kurt groaned, his Master was right… it hurt so good. He gasped for air, moans falling from his lips and he didn't know if it was from the pleasure or the pain.

When Blaine reached the end he tied a knot in the two strands then split them wrapping one back on itself and bringing it back to meet the other, he tied them securely then left a gap and tied another knot to form a loop.

"Feel that my pet, all bound up tight you're at my mercy aren't you and you love it." Blaine whispered bringing his lips right next to Kurt's.

"Yes… oh…Master…" Kurt gasped "Yes… please… Master…more." He said as he tried to lean in for a kiss.

Pulling his mouth away Blaine said "No no pet no kisses for you but don't worry, my boy, I'm going to make you feel so good." He crooked his index finger in the loop and pulled it downwards, bending Kurt's cock to point towards the ground.

Kurt tried to hold back the urge to cry out, but Master's voice urged him on, told him to let it out, to let it go, to give it all up to him. There was a howl of pain, the Fashionista cried out loudly, as no mercy was shown his bound cock.

Blaine nuzzled at the boy's neck, nipping at the flesh and sucking it into his mouth, leaving tiny love bites marking the perfect skin. When the cry had died down he let go of the loop and the cock swung back up, causing Kurt to cry out again in pleasure/pain combined with the surprise of the sudden action.

Short but well manicured fingernails, were dragged down his chest and over his abs, scratching the skin. Somewhere at the back of his mind a voice said 'abrasion was two days ago', and he almost laughed.

"Love your body." A voice said in his ear, as a hand returned to fondling his balls. "So hard and perfect I could keep you like this for hours, at the mercy of my touch and voice. Here because you choose to be."

He lightly slapped the balls that he'd been gently fondling and caused a sharp intake of breath from his prisoner. He repeated the action, they weren't hard slaps, and they didn't need to be.

"There are so many possibilities, so many things I could do to you while I have you like this, I'm spoilt for choices."

Another slap, followed by gentle fondling kept Kurt from ever knowing what to expect, a slap or a caress. The pattern was erratic; it drove the breath from his lungs and caused him to gasp in arousal and need. He'd never dreamed that he would enjoy this, not in a million years.

The gentle caress started to pull insistently downwards again, pulling groans and whimpers of pain from the bound boy. The longer his balls were held, pulled tight like that, the louder the moans grew; he cried out, his upper body starting to pull at the chains. The mouth returned to suck and lick at that same ear and he stilled, the power of tender touch merged with the harsh punishment being afforded to his genitals was incredible.

Blaine stroked a hand lightly across that strong chest then crossed the room back to his bag. "Of course, with limitless ideas, we could be here for quite sometime."

He pulled out a bag of mini clothespins and some other items. He paused to shed the sweatpants he had thrown on this morning, the rustle of material catching Kurt's attention. When he returned to his perfect little boy, he crouched in front of him and one by one started to attach the pins to the not-so-loose sac. Kurt bucked and flinched crying out quietly, his voice now sounding a little hoarse. He had reached 8 when the begging started.

"Please… Master… god… please… no more… it hurts… can't take it… please, Master… take them off. Make it stop… Master… please."

Blaine listened and watched carefully, making sure he didn't miss the safe word mix in Kurt's moans, when he was satisfied that his boy had not yet reached his limit he quickly added another two. Then he straightened up and stood in front of the older man, his body was taut, held tense against the onslaught of pain that would be firing up his spine from his groin. Blaine's hands found Kurt's nipples and played gently with them, before he leaned forward and licked at one, sucking on it gently.

The submissive was incoherent at this point; a steady stream of words and noises fell from his mouth and his Master kept a close eye on him. He reached off to the side and added a weight to the loop on the cock binding, pulling it downwards and Kurt cried out loudly again, his words becoming clearer.

The dark haired man kissed him hard on the lips, thrusting his tongue into the other man's mouth and plundering it harshly. Hands ran over Kurt's body, caressing every part of skin that he could reach. He eventually had to break the kiss for them to breath and the bound man was breathing raggedly. Blaine knew if Kurt had cried out while the pins were going on, he was going to scream when they came off.

Blaine reached for the first one and eased it off one at a time. Once he had removed all the pins he paused, waited as blood flood back into the tortured flesh, and Kurt screamed in pain. His voice was raw by the time the last pin came free and he was sagging in the chains. Tears tracked down his face from under the blindfold. Blaine smiled warmly, although it was unseen by his pet; they were so close to achieving what he felt the boy needed.

"Hush, my boy, its all ok, its all fine. Let it all out, let it go." His tone was gentle as he knelt down and licked at the sore ball sac that had pulled up tight.

Standing he eased the weight from the loop and set it aside again, his hand reached for a small multi tailed whip, small enough it could hang nicely on a key chain. He lightly drummed his fingers against the tortured sac for a few moments then, as he held the still bound cock out of the way with one hand, he flicked the whip at it the tightening balls with the other.

Kurt yelped and tensed back up, his muscles popping out under porcelain skin. Blaine flicked his wrist again; the thin tails stung the already throbbing flesh. The fourth strike, the forth strike it was Kurt's undoing.

"RED." He cried out.

Blaine immediately stopped what he was doing and reached up to unbind his torture pet. He easily caught him before he could hit the ground. "It's ok sweetheart, I've got you, its all ok, your safe, its over, its ok." He held the older man cradled against him and carried him to the bed.

Still holding him in his arms he continued to whisper soothing words and kissed his boy's lust heated skin. Blaine whispered soothing words to the whimpering young man. "That's it, my pet, let it out, let it all go… its all going to be ok, its over now, you're safe. Its over."

Kurt sobbed and whimpered until he fell asleep in that warm embrace, the soft words of his Master, his protector, murmured quietly in his ear.

The End.
