A/N: Yeah update freaking finally! Sorry I know I've kept you guys waiting. Was getting used to new working hours. And I got a new beta Claire! She's really great and helping me a lot. Hope you enjoy this chapter.

This is a horrible idea, why did I agree to this? This thought was on loop in Sebastian's head the minutes he stepped foot inside the Hummel-Hudson house. It was not that he was getting cold feet about being in a relationship with Kurt, but that he might not even get to be in a relationship with Kurt at all. There were three pairs of very serious eyes locked onto him right now and he didn't know what to do.

"So, you're telling me that you've been staying at Sebastian's place whenever I'm not at home for the last month?!" Burt looked angry. No, not quite angry, but he was definitely not happy about this situation.

"Umm...yes."Kurt answered weakly.

"Burt, I'm sorry! I didn't know! I thought Kurt was having sleepover with the girls!" Finn exclaimed.

Kurt rolled his eyes so hard they almost disappeared, and Sam chuckled lightly.

"Sam, you knew?" Burt asked.

"I-well, yes Burt...but-"

"And you didn't think about telling me that my son is seeing someone, and on top of that, sleeping in his house?"

"Dad! We didn't do anything." That was a total lie, but Kurt was not going to talk about his quasi sex life to his father and brothers.

"We...cuddle! Yes, like a lot. We just cuddle." Sebastian gave Burt reassuring nod, hoping it would make this more convincing.

Sebastian had never been this nervous in his entire life. Burt Hummel was looking at him with the 'I'm judging you' look.

And the worse was when Burt told Kurt to help Carole in the kitchen. Kurt knew this was Burt's way of saying he wanted to intimidate the boy so Kurt was reluctant to leave Sebastian alone, but his father gave him a serious look in the eyes. Kurt had no choice but to leave Sebastian with his protective father and brothers.

"You don't think dad's gonna scare him away, do you?" Kurt asked nervously once he entered the kitchen

Carole smiled and rubbed his shoulder "Intimidate him a little I'm sure, but I don't think your boyfriend will be scared away."

"Well, that's before he knew about the shotgun."

"Then let me tell you some good news: I hid it." Carole smiled rather proudly as Kurt squealed and hugged her.

"I just hope Bas won't say anything inappropriate..."

"Is this where you're gonna say you will shoot me with your shotgun if I hurt your son..."

"So you know about the shotgun."

"I-yes, Nick and Jeff told me, they said Blaine used to be scared..." Sebastian stopped mid-sentence when he realised it was a really bad idea to bring up Blaine the ex.

"Apparently he was not scared enough and I will not make the same mistake. It doesn't matter if Carole or Kurt try to hide my gun. You hurt my boy and I will buy every gun in Ohio and shoot you. Is that clear?"

"Crystal." Sebastian was proud his voice didn't quake. He wondered if that was adrenaline that was keeping him going.

Sam grinned like he was enjoying the show which made Sebastian quite annoyed.

"Whatever you and Kurt are doing, I want you two to take it slow. I don't think you're gonna transfer school to be with him, right? And I'm not gonna let him transfer back to Dalton. I want him to focus on school."

"Understandable. I don't think I can handle pu-transfering in the middle of my final year as well."

Sebastian mentally cursed about almost slipping on his opinion of public school.

"And I don't want you or Kurt stay over at each other's houses again without asking me first. I don't know about your parents, but just because I can't be home as often, doesn't mean I've stopped taking care of my son."

"That's very caring. My mum and my little sister are very fond of Kurt, that's why they are always asking him to stay over. I promise I never did anything that Kurt didn't want me to."

Burt seemed to be happy with the answer and gave him a nod approval nod while Sam gave him a little thumbs up.

Just when Sebastian was wondering if this interrogation was going to go on forever, Kurt came to the rescue with a big tray of honey roasted chicken. "Dinner is ready!" Kurt and Carole busied themselves with setting up the plates and the rest of the food in the dining room.

Finn and Sam jumped from the seats instantly and ran towards the dining room like they have been starved for a century. "Yay food!"

Burt stood up and gave a light pat on Sebastian's shoulder "You are gonna love Carole's cooking."

"It smells amazing." Sebastian said truthfully as he followed Burt into the dining room and Kurt was at his side the moment he stepped in.

"You're alive. In one piece." Kurt whispered as Sebastian pulled him into his arms.

"I know, I'm surprised as well. Your dad is...something."

"No one pushes the Hummels around."

"Yeah, I can tell." Sebastian said in relief.

The boys stepped away from each other awkwardly when they heard Burt clear his throat from his seat.

"Sebastian. Kurt. Sit before these boys eat all the food." Carole urged them to sit next to her.

Thank god Burt married the sweetest woman (other than his mum) on earth. Carole kept making small talk through dinner and distracted Burt when the old man tried to stare down Sebastian. Kurt held Sebastian's hand under the table whenever he got chance, hoping it would calm him down a little more.

Sebastian was doing an excellent job charming Carole, making her laugh at all the funny little stories about him and Edith, Lucas and Sisi.

After dinner, Carole insisted she and Burt could clear up, Burt saw the look of 'we need to talk' so he didn't argue. Carole winked at Kurt before urging Burt into the kitchen.

"Be nice to that boy, Burt."

"I'm just making sure he understands he can't hurt Kurt."

"You're scaring both of them."

"I'm protecting Kurt."

"Kurt is practically an adult now. I think he knows what he's doing."

Burt sighed "I know, but he's still my little boy to me."

"I know. But you have to trust Kurt. He's a great, independent, smart, young man now because you raised him well."

"I just wish I could spend more time with him before he goes off to New York."

"If you are worried about that, we'll just have to make sure we have as many Friday dinners as possible, okay?"

"Have I told you I love you lately? You're the best" Burt kissed her on the cheek.

"I know, and be nice to Sebastian. He seems very nice, don't you think."

"It's because he wouldn't shut up about how nice your cooking was"

"My cooking is nice. You should know the best" Carole smirked proudly.

"Yes." Burt couldn't help but smile

"Kurt is a grown man now, let him handle his relationship."

"Alright alright."

"Now, help me clear up this mess." Carole handed Burt a pile of dirty dishes

"Bas..stop it." Kurt whispered

"You don't like it?" Kurt could feel the other's smile against his ear

Sam and Finn were on their second round of Call of Duty while the couple snuggled on the couch.

Well, more like Kurt was sitting on Sebastian's lap while the other wrapped his arms around Kurt's slim waist.

Kurt bit his bottom lip in an effort not to moan when Sebastian nipped his jawline and the sensitive spot just under his ear. "Bas..."

Sebastian just hummed and start rubbing his hand along Kurt's back.

"Dad's coming in anytime soon, you should stop if you wanna live." Kurt mumbled a warning.

"Can we go to your room, please..." Sebastian said quietly as he kissed Kurt's neck

"Dude, you know we're here, right? That's my little brother." Finn glared at them.

"I found it rather hot to be honest. You go, my boy." Sam winked at Kurt.

"Sam, dear, I wonder about your sexuality sometimes." Kurt teased while leaning closer to Sebastian

"Oh, you'll be the first to know if anything changes." Sam joked.

Sebastian, however didn't find it funny. At All. "Blondie, Kurt's mine."

"Yes I am, so no need to jealous." Kurt cupped Sebastian's face with his hands and kissed him.

"I didn't need to see that!" Finn covered his eyes instantly while Sam wolf whistled and cat called.

"Please can we go to your room." Sebastian almost sounded like he was begging.

"Alright. I'll leave you boys here . I'm gonna show my boyfriend my beautiful décor in my room."

"Oh is that what you call it now." Sam teased

"Shut up Sam Evans." Kurt glared at Sam one last time before pulling Sebastian out of the living room.

"Does he normally talk like that to you?"

"Who?" Kurt lifted his head up from Sebastian's chest as they cuddled on his bed.

"...Sam."

"Bas. We've talked about this."

"I know, but he called you 'my boy', and he was borderline flirting with you. Right in front of me. I don't like it."

"Sam just likes to tease, that's all. Trust me, okay? I'm here, with you, right?" Kurt kissed Sebastian with a big 'muah' making the boy laughed a little.

"Mr. Valentine...I was wondering, would you like to have dinner with me on your birthday?"

"I thought that was the plan."

"No, your plan was to have dinner in bed and play some DVDs and not watch them."

"That sounds like a perfect birthday plan to me. You were part of the plan anyway."

"It's our first Valentine's Day together. Please?"

"No...no puppy eyes. No-fine."

"Yes!" Kurt squeaked and hugged Sebastian closer.

"Kurt Hummel what did you do to me?" Sebastian smiled as he ran his hand along Kurt's back

"What do you mean?"

"I was never like this. You and your puppy eyes..."

"Well, I think we all agree that I'm irresistible." Kurt smirked.

Sebastian smiled and placed butterfly kisses along Kurt's face and neck and said in a low voice "Hmm, so adorable, so pretty and sexy..."

"Oh god." Kurt felt hot all of a sudden and he was sure he was blushing.

Sebastian moved a little closer and licked Kurt's bottom lip lightly and slipped his hand under Kurt's top.

"Bas...we can't here. Dad will kill you if he sees us and I want this relationship to last longer than a month."

"Babe, we need to think about a proper make out place. I can't handle being cockblocked all of the time anymore. I'm dying. I need you." Sebastian buried his face in the crook of Kurt's neck.

"I know...I promise I'm telling the guys soon. I blackmailed Finn not to say anything. I wanna introduce you properly and then I can start parading you around everywhere I go." Kurt giggled at his own thoughts.

"I always knew you were lusting after my body."

"You do have a very nice ass."

"Nice? My ass is perfect."

"No, you can have great ass, I've got the perfect ass." Kurt gave Sebastian his grade A 'Bitch please' face and Sebastian chuckled at his look.

"Of course. Why else I am dating you." Sebastian slipped his hand into Kurt's jeans and squeezed his ass "Fuck...I should have known you went commando today. These freaking jeans..."

Kurt grinned at his boyfriend's reaction, he liked the way Sebastian goes crazy just touching him.

When Kurt was about to tell Sebastian to finger him, Burt came in the room "Boys it's late I think-Oh."

"Dad!" Kurt panicked and literally pushed Sebastian away and sent him flying off the bed

"Ow, Kurt!" Sebastian rubbed the spot where he hit his head when he fell onto the floor

"Sorry! Sorry." Kurt helped him up and then blushed like a tomato at the look from Burt

"Sebastian, it's late. Shouldn't you be leaving soon? It's a two hours drive back to your house."

What Burt really meant is keep your freaking hands off my baby boy or I'll make sure you never see the sunrise tomorrow.

"Yes, thank you for reminding me sir. I should...go." Sebastian quickly straightened his clothes out a little and awkwardly walked towards the door.

"I'll see you off!" Kurt called and ran to his side pulling on his hand to escape from Burt

The two of them meet again on Sunday morning. Sebastian arrived after Kurt texted him that Burt had gone down to the shop.

"Is that a Lamborghini Gallardo?!" Kurt gasped at the look of the shining new car Sebastian stepped out of.

"Yes, brand new delivered from Italy. Grandpa thinks I should get something nice for my 18th birthday."

"That's really nice." Kurt hovered his hand over the outline of the car.

"Want a ride? Or you can ride me in it. I'm fine with both."

"Sebastian!" Kurt exclaimed embarrassingly

"You want it." Sebastian smirked in a way that made Kurt want to smack him, but Kurt had a weakness for cars, extremely beautiful and expensive sports cars, and the thought of making out with his boyfriend in a Lamborghini was, well, arousing.

Sebastian smiled at the way Kurt's eyes sparkled at the look of his baby. He urged Kurt to get into the car.

"Where to, my princess?"

Kurt rolled his eyes at the nickname "You know, I'm in a great mood because I'm in this great car so I'm not even gonna bitch about that name. I need to meet the girls in the afternoon though. So it gives you...3 hours?"

"You and your girls night. Why do you even have a girls night on Sunday? You're gonna see them tomorrow."

"This is the night we can talk about our boys as we want to. Mercedes and Rachel can't really talk about them when they are around."

"Do you talk about me?" Sebastian fired up the engines and smoothly pulled out of the driveway

"I don't know...you worry about me complaining about you?"

"Me? I'm perfect babe. You have nothing to complain of."

"And so modest. I'm the luckiest boy in this world." Kurt teased.

"So am I." Sebastian smiled back.

"Ouch! My head!" Kurt dropped himself on top of Sebastian, defeated

"Guess now we know sports car are not made for a certain sport." Sebastian sighed with a little frustration.

"Damn it, I'm gonna have cramps." Kurt tried to stretch out his legs and roll over back into the passenger seat

"Remind me when we are making out in someone's car next time, it's yours."

"Absolutely."

They looked at each other for a second and broke out into laughter

"As soon as we make official announcement to everyone. I'm gonna kidnap you to our Columbus town house and just fuck you for a whole weekend." Sebastian wrapped his arm around Kurt's shoulder.

"Someone's eager."

"Don't pretend you didn't go commando on purpose the other day. You were so hoping I would finger you or give you a hand job."

"Well..."

Kurt was saved by sound of his Dancing Queen ringtone.

"Oh, I have to take this." Kurt got out of the car for the call.

Sebastian looked out of the window and saw Kurt giggling and he smiled. He always love the way Kurt laughed, and how it made other people smile.

Sebastian rolled down the window a little, not trying to eavesdrop, he just wanted to hear Kurt's laughter. Instead he heard 'Of course I'll meet you David.', and his heart dropped. Everything after that was a blur, until Kurt knocked on the window "Bas, are you okay?"

"Y-yes. Sorry just spaced out a bit."

Kurt placed a quick kiss on Sebastian's cheek "Sorry I have to go early. Meeting a friend before seeing the girls."

"Okay." It came out harsher than Sebastian planned. He tried to stay calm. Apparently it was an epic fail because Kurt was frowning.

"Please don't be mad. I haven't seen him for a while. I promise I have a great plan for you on your birthday?"

"Please don't throw a party..."

"Don't think about it and don't complain. Just promise me you'll meet me for dinner.."

"But I don't know your plan."

"You don't need to know."

"I don't like surprises."

"But you like me." Kurt smiled

"That I do."

"I'll let you know the details. Call you tonight?"

"Okay."

It was wrong. It was so very wrong, Sebastian knew it but he couldn't help it; and he knew Kurt would be so mad when or if he found out.

Sebastian followed Kurt to the Lima shopping mall. He was lucky it was the Sunday before Valentine's day and that loads of people were out buying last minutes presents for their lovers. Sebastian easily hid himself between groups of people while following Kurt to a small cafe.

Kurt was meeting a jock, which was weird. Sebastian didn't remember if Kurt was friends with other jocks other than the boys in New Direction. What worried him was the way the guy was looking at Kurt while he talked. Fucking glassy heart eyes like how Blaine the hobbit used to look at Kurt.

Sebastian watched the two of them talk for almost an hour, and the jock nodded happily and smiled like a freaking puppy when Kurt said something to him. And his boyfriend occasionally gave the boy some comforting pats on the shoulder.

Sebastian went home to his Dalton dorm, completely pissed off. He felt anger boiling inside of him. Someone could probably even smell the jealousy on him, so naturally Lucas noticed.

"What happened?"

"Kurt happened."

"I'm lost here. What?"

"Kurt told me he was meeting a friend, I followed him-don't ask" Sebastian held up his finger to stop Lucas from asking "I saw him with this jock...in the cafe in the mall. That jock was looking at him with these puppy glassy heart eyes."

"Wait...was he named David?"

"How do you know?"

"Remember that time you sabotaged my 'date' with Kurt?" Lucas' fingers quoted date. "I was late, and Kurt was talking to this jock when I arrived. I remember he called him David."

"Fuck...he never told me about any jock he know other then the glee guys."

"I don't know, they looked like they were talking about something serious."

"Oh god, Kurt is going to leave me." Sebastian dropped on his bed

Lucas laughed "You're crazy. He just asked you to meet his dad. Why would he do that if he's going to leave you?"

"But...what if this guy is wooing Kurt?"

"Wow. I didn't realise you were so insecure, brother." Lucas teased

"Shut up." Sebastian huffed and buried his face into his pillows.

It was the morning of Sebastian's birthday. Kurt's car was parked around the corner of the Smythe's house.

"Holy fuck, Kurt." Sebastian was panting hard as he came down. He dropped his head onto the backseat.

Kurt looked up at Sebastian, smiling affectionately between his legs. "I guess this means you like your birthday blow job."

"I love my birthday blow job. How the hell do you get better at this every time."

"I learned from the best." Kurt smirked.

Sebastian pulled Kurt up onto his lap and wrapped his fingers around Kurt's hard on, "Yes you did, and I'm gonna take care of you."

It didn't take long for Kurt to get his orgasm. Sebastian cleaned them both up and they snuggled on the seats. "How come it took us this long to realise your car is the best make out location?"

"Hmm, I hope we fine another best make out location soon. It smells like sex here and I don't want to explain this to anyone when I take my baby in for a wash."

"I thought I was your baby." Sebastian faked a sad pout.

"You're my favourite." Kurt kissed him with a 'muah'.

"So what's your plan for your favourite's birthday? I hope I get more than just a birthday blow job on my 18th."

"No spoilers. All you need to do is be at Breadstix at 7pm tonight. No earlier or later. 7pm sharp. Can you do that for me, big boy?"

"Just for you, babe."

"I know. Now I promised Edie she can have you for the afternoon. Go home now and I'll see you later?"

"What? So I only get this for now?"

"Don't make me spank you. It's your 18th birthday. Edie wanted to do the mother job. I'll see you in a few hours."

"Fine. It better be good."

"I promise it will be."

Edith was happy to have Sebastian for the afternoon, along with Lucas and Sienna. Edie made him a really nice birthday cake and gave him a key for birthday.

"What's this for?" Sebastian asked in surprise.

"Remember I didn't let you access the trust fund your grandfather left you?"

"Yes...because you said I'd spent it all on wine and cars."

"Yes, and I know what was the best investment for it." Edith smiled proudly and pulled out a envelope and handed to Sebastian "Open it."

It was a ownership contract for a property in the Upper East Side, in New York. Under the name of Sebastian Charles Smythe.

"Momma...this is, for me?" Sebastian was shocked, he didn't know what to expect for his birthday presents from his mother but he certainly didn't expect this.

"Yes, I bought it with your trust fund money. It's brand new. You are in charge of it. I don't care if you want to rent it out, sell it...well maybe not sell it. It took me a while to find it." Edith laughed, "You can live there when you go to NYU."

"Momma...thank you."

"I know you want to go to NYU, I'm 100% behind your back." Edith kissed Sebastian's face and ruffled his hair while Lucas and Sienna chuckled.

"Momma! My hair..."

Edith sighed "Look at you, 18 already. My little boy is all grown up now."

"Please don't get sappy on me." Edith just smiled and gave him a quick hug.

Lucas cleared his throat before handing a small box to Sebastian, "It's not much, but I hope you like it."

Sebastian opened it with a questioning look, inside sat a hard back Les Misérable. It looked awfully familiar but Sebastian couldn't pin point why.

"Remember we had this big fight when I was five and I tore your book apart? I found it in your room and got it rebound and repaired. I got it leather bound, so it should give better protection to it-"

Lucas got cut off when Sebastian pulled him into a hug suddenly.

"Thank you." Sebastian muttered into Lucas' neck.

"Bas! Bas it's my turn!" Sienna pouted and jumping up and down to get everyone's attention.

"Yes little princess. What do you have for me huh?" Sebastian scooped her into his arms and kissed her on the cheek.

Sienna giggled and pushed a little doll and a card to Sebastian's chest.

"You said you miss me a lot in school. So I made this for you. See, This is me, in the pink dress mama picked for me! And I drew this...this is me, you and Kurtie! Mama said Kurtie makes you happy, so there's Kurtie for you."

"This is so lovely, did you really make this?"

"Mama and Lola helped. But I stuffed the cotton in it. And I picked out the buttons for the eyes."

"This is amazing Sisi, I love it." Sebastian smiled brightly at Sienna and bounced her up and down a little between his arms.

They spent the next few hours talking together, Edith was dying to hear about Sebastian meeting Kurt's parents. Sebastian proudly said he swept Carol off her feet and impressed the boys too. He admitted Burt was intimidating but he thought it was safe to say he passed the test.

Sebastian remembered what Kurt had told him: 7pm sharp, no early or late. That was why he was sitting in his car in the Breadstix parking lot, waiting for the clock to strike 7. He was too nervous about Kurt's plan, that he couldn't sit still at home to wait so he went out to go for a drive and ended up at Breadstix one hour earlier than the plan.

Kurt arrived 15 minutes after Sebastian, but he didn't noticed the car in the corner as he was too busy humming songs and pulling a bunch of balloons into the restaurant. Sebastian chuckled and shook his head, he knew Kurt was planning some party thing, he knew from the day Kurt found out about his birthday. No matter how many times Sebastian told the boy he didn't want a party Kurt just had to throw one.

Sebastian was thinking about how he was going to tease Kurt later when he saw the same jock from the mall go into Breadstix. Waves of anger washed over Sebastian, he was sure that David was here to see Kurt. His mind was battling about whether he should go inside or not.

He instantly regretted it when he finally made the decision to check on Kurt. Sebastian walked in and saw David holding Kurt's hand, in an affectionate way that made him sick to his stomach.

"Kurt...I really like you. Please give me a chance." That's all Sebastian needed to hear from David before he gone mad.

"What the fuck is this?" Kurt snapped his head up and found Sebastian standing there. His voice filled with anger and sadness that Kurt have never heard before

"Bas?" Kurt looked up in surprise

"Who are you?" Sebastian stormed over the boys.

"Bas, this is David, he's a friend" Kurt glared at his boyfriend.

"Funny cause I haven't heard about that name until now." Sebastian huffed.

"What are you implying?" Kurt frowned.

"I don't appreciate you seeing someone behind my back."

"What your problem with me?!" David rose from the seat and grabbed Sebastian's collar.

"You, chubby! You stay the fuck away from my boyfriend! Don't think I didn't see you with those disgusting heart eyes. Don't even dare to think about Kurt. He's mine." Sebastian pushed the boy away from him.

"Sebastian!"

"No, sorry Kurt, I should not have interrupted your date today. I will go." David quickly went away.

"David! Wait-where are you going?!" Kurt ran after him.

"Are you really going after him? You are not going anywhere!" Sebastian followed Kurt out of the restaurant and grabbed his wrist.

"He's a friend! And you are being extremely rude!"

"Sorry if I'm angry that my boyfriend is meeting someone behind my back!"

"David is a friend that in need! Sebastian why don't you trust me?!" Angry and sad tears starting to fall from Kurt's eyes.

Sebastian felt bad at the sight but he was so angry right now he couldn't bring himself to comfort Kurt.

"Do you not see how he's giving you those damn heart eyes? Like Anderson used to look at you all the time! He just confessed he likes you!"

"So you think I'd just thrown myself at anyone whoever has a slight interest of me?!"

"That's not what I'm saying!"

"You have trust issue, Sebastian!" Kurt shouted in frustration.

"Maybe I'd have had more confident about us if you would put out-"

Kurt slapped him hard across the face, he was never a violent person, but this was too much.

"You think I don't want to be in this relationship just because I wouldn't actually have sex with you?! Fine! Go date someone from Scandals!"

"What do you mean?!"

"We obviously have polar opposite views on relationship. Maybe we should stop..." Kurt's voice cracked at the last few words.

"No! No Kurt, sorry babe-"

"Don't 'babe' me! I don't want to talk to you right now!" Kurt wiped away his tears before walking towards his car.

"Kurt!" Sebastian ran after him "Please I'm sorry!"

Kurt turned and put on his cold expression "After bringing you to meet my dad, after all the stuffs I've done for today-I, maybe we're wrong. Maybe you should go find yourself a new boyfriend for your birthday. Goodbye Sebastian." Kurt jumped into his car and drove away before the birthday boy could say anything.

A/N: Alright, don't hate me please. Also, I'm going to start posting these to AO3, i guess it's easier for people who wanted to download it.
