Six months later, things were still perfect with Kurt and Blaine. Kurt still misbehaved sometimes and he was still punished for it, but otherwise things went along smoothly. Kurt was lying on the couch reading when Blaine came home from work.

"Hey, baby," Kurt called out softly. "Good day?"

Blaine came into the room, leaning down and kissed him lightly on the lips.

"Sure did, babe. You?"

Kurt hesitated, but decided it was best to tell the truth. "I... I went out today," he admitted softly. "Without permission..." It was still one of their strict rules that Kurt went nowhere without permission.

Blaine pulled back slowly. "You did what!? Did you wear the collar?"

"I... I couldn't find it," Kurt whispered. It was true, he had looked for it.

Blaine stood up straight, his face hard as stone. "On your knees."

Kurt whimpered, but nodded, dropping to his knees and bowing his head. "I'm sorry, Sir."

"You know, Kurt. You know that going out means disappointing me. And you know that going out without the collar means more disappointment and bigger punishment. You deserve to be punished, don't you, Kurt?" Blaine stood completely still.

"Yes, Sir," Kurt whimpered, looking at the floor. "I deserve it, Sir." They still hadn't worked up to sexual punishments yet, but Kurt hadn't misbehaved this badly in months and he knew it was coming.

"I need you on the bed, naked," Blaine said firmly. It was time. Blaine knew that Kurt was ready for it and now was the time. Blaine didn't want to hold back any longer. He had been making love to Kurt for months now, but now, he was going to fuck him for real. This was it.

"Y-Yes, Sir," Kurt nodded, scrambling to his feet and practically running to the bedroom. He stripped quickly and laid down on the bed. He was a little scared, but not much. He trusted Blaine and he deserved the punishment.

Blaine gave him a few minutes to get ready before walking in and finding him naked on the bed. He smirked as he walked around the bed. "Have you been a bad boy, Kurt?"

Kurt whimpered. "Y-Yes, Sir. I need you to p-punish me, Sir..."

“I will, baby. I'm not holding it in any longer." Blaine bit his lip as he looked at Kurt, trying to figure out how to do this. "On your hands and knees."

Kurt pulled himself up onto his hands and knees, only shaking a little bit. Meanwhile, Blaine started biting down on Kurt's ass cheeks softly, taking his time to mark them. Whining, Kurt pushed himself back against Blaine's mouth.

"Hold still," Blaine growled, his domination growing stronger every second.

"Y-Yes, Sir," Kurt nodded. "Sorry, Sir!" He tried hard to stay as still as he could.

Blaine left a few dark hickeys all over his ass and hips before licking down to his hole. "Mmm..."

Kurt whined and he couldn't help but squirm. Blaine slapped him hard over his right ass cheek. "No moving!"

"Yes, Sir!" Kurt yelped in pain, though he had a raging hard on that was starting to ache from the lack of touch already.

Blaine smirked. "You're going to take this like my good slave." Then he pressed a finger against Kurt's hole, still completely clothed himself. Kurt whined desperately as Blaine pushed against his entrance, then he bit his lip. He wasn't supposed to be enjoying this, it was a punishment.

Blaine pressed the finger inside roughly. "Quiet!" he demanded.

Kurt nodded, panting hard. He could help but let out a groan as Blaine added another finger.

Blaine slid the fingers in and out quickly, adding a third one as well. When he considered Kurt stretched enough, he took them out and then slowly stripped until he was naked. Kurt was grinding his ass backwards desperately, he needed Blaine inside him. He kept trying to remind himself that it was supposed to be a punishment.

Blaine finished and slicked himself up with some lube before crawling up over Kurt and in one movement, pressing himself into Kurt quickly.

Kurt let out a loud cry. Even stretched, it hurt and he felt his erection throbbing below him.

Blaine fucked into him roughly again, harder this time. "Silence, I said," he growled.

"I c-can't, Blaine!" Kurt panted before biting his lip, knowing he'd be in trouble for calling him 'Blaine' during a punishment.

Blaine growled louder, biting at Kurt's shoulder. "What am I, Kurt?" he said sharply between quick, rough thrusts onto Kurt's prostate.

"My... My Master!" Kurt cried weakly, trying not to fall apart.

"That's fucking right," Blaine panted, pushing into Kurt over and over, harder and harder for every thrust. "And you call me Master."

Kurt let out a small sob and nodded. "Yes, M-Master!"

Blaine pounded into him harder, making himself last longer than ever. Eventually, he came inside of Kurt, completely spent and exhausted.

"M-Master..." Kurt sobbed. "I n-need to come. Please can I come?" He was desperate, he'd held off as long as he could.

Blaine shook his head against Kurt's sweaty back. "You have one hour before you can come."

Kurt whimpered, crying weakly. "C-Can I at least use a cock ring?"

Blaine nodded with a smile. He took up a cock ring from the nightstand that he had already prepared and slid it onto Kurt's erection.

Letting out a pained cry, Kurt looked carefully at Blaine. "Are you... Are you still Master?" he asked hesitantly.

"For one hour, yes." Blaine pulled out of Kurt and slumped down against the mattress.

Kurt pouted unhappily. "Yes, Master,” he whispered. "Is there anything you'd like me to do?"

Blaine nodded, his dominance still taking over the bigger part of him. "I think there are some dished left from earlier, plus some clothes that need to be folded. Come back here when you're done."

Kurt nodded and walked off to do his tasks, head bowed, tears running down his face. His skin was flushed with both shame and humiliation. He came back half an hour later and dropped on his knees by the bed, he was in pain, he was desperate. Right now he'd do anything to come.

Blaine was still laying in bed, completely blown away by what had just happened. He didn't even notice that Kurt had gotten back. He soon fell asleep and Kurt didn't dare to wake him up. He stayed on his knees, whimpering quietly in pain and desperation for another hour until Blaine finally woke up.

Blaine woke up and found Kurt still on his knees, shaking. He got up right in front of his sub and held his soft cock against Kurt's lips. "Serve me and wait for your permission."

"Y-Yes Master," Kurt whispered, wrapping his lips around Blaine's erection and concentrating on giving him a really good blowjob.

Blaine groaned quietly at the sensation. Kurt's lips were like silk against his cock and it felt amazing. It didn't take long until he was completely hard and he began to thrust slowly into Kurt's wet heat, wanting to get deeper. In response, Kurt closed his eyes and tried to remember everything he'd been taught. He relaxed his throat and began to deep-throat Blaine.

Blaine moaned and gripped Kurt's hair. "Come for me, Kurt!" he screamed out, letting go and erupting into Kurt's mouth.

Slipping off the cock ring from his own dick, Kurt cried out in pain and relief as he came hard.

Blaine pulled out once Kurt had swallowed and he fell back onto the bed, breathing hard. "You're so fucking good at that," he panted. Kurt whimpered softly, still sore and over sensitive.

"Come here, baby," Blaine said softly, trying desperately to reach for Kurt. "Need you in my arms."

Kurt let out a soft cry and threw himself into Blaine's arms, clinging tightly and crying. "I'm s-sorry, Master..."

Blaine frowned as he rubbed Kurt's back. "Why are you sorry, sweetheart?"

"That I went out without your permission,” he whispered. "A-And that I didn't wear a collar and I... I m-made you mad at me."

Blaine kissed his shoulder gently. "I'm not mad anymore, sweetie. You took your punishment well. But you must never go out without permission and collar again. It's unacceptable."

"I know, Master. I'm s-sorry."

Blaine smiled and rubbed Kurt's back gently. "Kiss me, Kurt."

Kurt leaned up and kissed Blaine tenderly, his tongue exploring his mouth. Blaine kissed him back with a smile. A few minutes later, he pulled back, separating their lips with a small 'pop'. "...I love you."

"I love you too," he breathed. "Can I call you Blaine again?"

"Always after a punishment, Kurt," Blaine smiled, rubbing his thumb over Kurt's jaw.

Kurt nodded, curling close to Blaine's chest. "You've never made me call you 'Master' before..." he whispered.

Blaine bit his lip. "I know... But this relationship is starting to go further now," he said, his lips resting against Kurt's hair. "And I need you to understand that the punishments will get harder and rougher. Your body will learn to adjust to that."

"Yeah..." Kurt whispered hesitantly. "I'm just a little scared."

Blaine kissed his forehead gently. "It's all going to be alright. You always have your safe word, although I would prefer if you didn't use it."

Kurt nodded. "I nearly did today, but I knew I deserved it..."

"You will get used to it, baby. Everything will be fine in the end. You were really good today," he praised.

"Really?" Kurt asked softly.

"Really," Blaine confirmed. "You're always the perfect slave and the perfect boyfriend."

Kurt relaxed into Blaine's arms. "You're the perfect Master and the perfect boyfriend."

Blaine smiled and held Kurt closer. "Love you for always."

"Love you too." Kurt leant up and kissed Blaine's jawline. "I made you cheesecake, it's in the kitchen."

Blaine didn't make any effort to move. "Not now... Cuddles now, cheesecake later."

"It's white chocolate and raspberry," Kurt smiled, cuddling closer to Blaine. "Your favorite. That's why I left, I needed to get more chocolate. I wanted to surprise you."

"Well, I have a surprise for you too," Blaine grinned. "Because it's sort of a special someone's birthday tomorrow," he teased and nudged Kurt gently.

Kurt blushed. "I thought you'd forgotten. It's really not a big deal, I haven't celebrated my birthday since I was twelve..."

"I'd never forget," Blaine said softly and pressed a kiss to Kurt's nose. "Maybe we can save the cheesecake for tomorrow? You know I could never bake for you," he chuckled.

Kurt laughed. "Kind of depressing to make your own birthday cake, don't you think?" He chuckled and shook his head. "Really, don't worry about it."

Blaine smiled and kissed Kurt on the lips before sitting up. "I know you're exhausted. Go take a nap. I can fix everything I need to fix for tomorrow now instead and then I can be with you when you wake up."

Kurt nodded, crawling under the covers and curling on his side.

Blaine kissed his forehead and waited until Kurt was asleep before crawling out of bed and into the guest room. He needed to prepare.

:)

The clock was past midnight when Blaine woke Kurt up. He was dressed in a fancy suit and his hair was perfectly styled. "Wake up, my prince."

Kurt woke up in confusion, blinking at Blaine. "Why are you all dressed up?" he asked sleepily, rubbing at his eyes. "Are you going out?"

"We're going on a date á la Kurt and Blaine," the man smiled. He placed a beautiful pink rose on Kurt's chest.

Kurt sat up, stroking the rose's petals. "I'm naked,” he stated.

Blaine chuckled. "Nice observation," he said. "Go put on some clothes and call for me when you're done, babe."

Kurt rolled his eyes and dressed in tight, grey skinny jeans and a dark purple, close fitting shirt. "Ready, Blaine..." he called out.

Blaine came in again and smiled when he saw Kurt. "You look beautiful, baby." He kissed him on the cheek and linked their arms together. "You ready to go for a romantic birthday date?"

Kurt nodded. "Ready. Though you really didn't have to do anything..."

"Of course I did. It's my boyfriend's birthday, after all." He led Kurt into the guest room. He had set up candles all over the room. There was a small table in the middle of the floor with two chairs, flowers and a cake that looked pretty bad. "I tried to make a cake," Blaine blushed. "Not very successfully."

"It's beautiful." Kurt whispered, kissing Blaine softly. "Thank you for trying. It means so much to me,” he said honestly, very moved by everything Blaine had put together.

Blaine smiled. "There's more, honey."

Kurt looked at him, surprised. "What more can there possibly be?"

Blaine cupped Kurt's cheek. "In the history of this world, when someone wanted to show another person how much they loved them, they would propose. Have you heard of it?"

"No," Kurt said and shook his head. "What is it?"

Blaine took Kurt's hand in his own. "It means that you promise to marry that person. A marriage was sort of a big ceremony when you promised to love your partner until you die. The boy would take his lover's hand." Blaine squeezed Kurt's hand lightly. "Get down on one knee." Blaine did so. "And give his partner a ring to ask the question." Blaine smiled and held up a beautiful silver ring. "Kurt Hummel, I promise to love you, respect you and always value you as my highest priority in life. Will you agree to be with me forever? Will you marry me?"

Kurt was stunned, this was too amazing for words. It was beautiful. He still wasn't completely sure what was going on, but he dropped to his knees in front of Blaine and threw his arms around his neck, blissfully happy.

"Yes!" he whispered through tears. "Of course."

Blaine pulled back slightly and pressed his lips to Kurt's. "Now you're my fiancé. Promised to me forever."

"Forever and always," Kurt nodded. "But I already was yours."

"My everything," Blaine smiled. "How do you like the ring?" It was a simple silver ring with 'I'm yours' engraved on the inside.

"It's gorgeous," Kurt breathed, staring at it. "You shouldn't have."

"Yes, I should have," Blaine smiled softly. "Because I love you and you love me and we're perfect for each other."

Kurt nodded, pulling Blaine into another deep kiss.

The dark haired man pressed his fiancé close and kissed him back passionately. "I love you... I love you, I love you."

"And I you," Kurt breathed happily.

Blaine cupped Kurt's face and pressed another soft kiss to his lips. "You're the most beautiful boy I have ever seen."

Kurt blushed. "Not as gorgeous as you. Never as gorgeous as you."

Blaine smiled and kissed him once more before standing up. "Let's eat my horrible cake."

They ate the cake, which was very disgusting. It made them both laugh pretty hard because Blaine really was awful at baking. Then they stayed up for hours, talking and drinking wine until the sun rose over the buildings of New York. When they finally fell asleep, they were both happier than they'd ever been before. They had made it through many bumps in the road, but they always had each other. Their love was all they'd ever need to make it through.
