Chapter Twenty Three

Sebastian was surprised when he picked up his phone after leaving his grandfather and it was Rachel Berry on the line.

"Hello," she said sounding formal, "it has come to my attention that you and Kurt are dating. While we have had prior social meetings I propose a double date with myself and Sam. Will today around four work?"

It had been a weird weekend. He had stayed with Kurt the entire weekend, doing nothing more than just spending time with him and lazily kissing in his bed. He'd even helped Kurt make dinner for his family on Sunday night and stayed with them. It was surprising that Kurt's dad hadn't said anything, but Kurt had been acting off all weekend and Sebastian knew that it was about Blaine and him, not that either of them had actually brought it up.

"Um, does Kurt know about this?" Sebastian asked.

"Yes," said, "so you'll meet us at McKinley?"

Sebastian sighed. "Sure."

"That's great," Rachel said, "see you then."

"So that just happened," Sebastian said out loud and checked the time.

He had about three hours to go until he had to be at McKinley to go on a double date with Kurt and his crazy friend and he wasn't even that positive that Kurt really was alright with the whole arrangement. As he got into his car, he pulled his phone back out again and called Kurt.

"Hey," Kurt said, "so I take it Rachel called you?"

"Yup," Sebastian said, "so we're really doing that, going on a double date?"

He heard Kurt sigh. "Yeah. I know it's not ideal, but she thinks I was keeping you from her on purpose and you sort of get along with Sam so that works out."

"I guess," Sebastian said, "but alright, I just wanted to make sure she wasn't springing it on you as a surprise or something. So, I'll see you soon? She said four."

"Come earlier if you want," Kurt said, "it isn't like we have practice today. Mostly we'll be waiting for Sam to get done with the football players."

Sebastian started his car. "Alright."

He went to The Lima Bean first for a well needed coffee, and then, because he remembered that he'd told himself to stop and buy sugar, he drove to the nearest supermarket.

So, of course, he had to run straight into Blaine and Karofksy. He was almost surprised about seeing them together. After what Kurt told him, Sebastian had been sure that Blaine would go and break up with Karofksy but they still looked very much together.

Blaine was pushing the shopping cart and Karofksy walked next to him, putting things in the cart and asking Blaine for an opinion on the things he was buying. Blaine did seem distracted, but he still interacted with Blaine and there was nothing that could suggest to Sebastian that there was anything even wrong between them.

Sebastian didn't wait for them to see him, heading straight towards the baking aisle. He picked up the bag of sugar and continued towards check out. He spotted them again, and saw Karofksy kiss Blaine on the cheek but Blaine didn't react because he looked lost in his thoughts.

"Hello, how are you?"

He looked away and at his cashier who was smiling at him and had already scanned and packed his item in a bag.

"Good, good," he said quickly.

He slid his card on the credit card machine and took the receipt when it was offered to him.

"Thank you," he muttered and glanced back to where Blaine and Karofksy had been, but they were no longer there.

When he got to McKinley later, students were still hanging out the school, but most of them were gone. He parked where he usually did and then walked into the school and headed to the choir room.

He found Kurt in the office adjacent to the choir room

"I'm sorry about this," Kurt said as soon as he saw him, "but she's insistent."

Sebastian dropped into the seat across from Kurt. "I was just a bit surprised," Sebastian said, "I, um, I thought maybe you were going to break up with me. This past weekend, it felt like goodbye."

Kurt stood up and rounded the desk. "No," he said shaking his head, "no, that's not. I feel something for Blaine. I do. But, I feel something for you too and I couldn't – I can't forget that."

He stepped towards Sebastian, but didn't reach out to touch him.

"You're going to have to make a choice," Sebastian said, "we came into this knowing that."

Kurt reached down and grabbed his hands, pulling him up to his feet. "I choose to not make a choice. I choose to see what this is and it's the choice that I made when I decided to do this with you."

"But…"

"I broke up with Blaine," Kurt said, "and I didn't realize that I made a mistake until it was too late and when I came here to get him back he was with someone else even if that person is Dave Karofksy. I just – I can't break up with you now without knowing that it's the thing I want to do."

Before Sebastian could say anything, Rachel appeared.

"Oh, good," she said, "you're here. Sam will be ready in just a moment. He's getting changed."

"Thanks," Kurt said, "I'll go make sure everything's put away in there."

Rachel nodded, and when Sebastian made to follow him, she shook her head.

"I requested some time alone," Rachel said, "you've been around for a while now and I'm surprised I didn't catch on to what was going on. Kurt usually isn't that subtle. I just want to be able to impress upon you that if you hurt him, I will do my best to hurt you back."

Sebastian nodded slowly. "Sure," he said.

She stared at him for a while. "Good," she said.

Sam appeared, then, and he grinned at both of them. "Hey," he said at Sebastian and he kissed Rachel on the cheek.

"Alright, come on, let's get Kurt," Rachel said.

Sebastian walked past her to the choir room and he stopped short when he saw Blaine who stood in front of Kurt, looking a little bit lost. His eyes widened when he spotted Sebastian.

"We were just leaving," Kurt said.

"Oh," Blaine said, "I just wanted to talk to—"

"Hi, Blaine," Rachel said, "were you looking for me?"

"We're going on a double date," Sam announced.

Sebastian could almost feel the shock rolling off of Blaine.

"But if you wanted to call up your boyfriend we could turn it into a triple," Sam added as he put his jacket on and when Sebastian looked at Kurt, he knew that Kurt wouldn't look too happy.

"I—"

Rachel stepped forward. "Did you want to talk to me, Blaine?" she asked, "or ask me something?"

Blaine shook his head. "No," he said, "I forgot why I came here."

Sebastian, though, had a pretty good idea why he was there, and he knew that Kurt would as well. He also knew that Kurt wouldn't admit it or stay.

"Alright then," Rachel said and she and Sam headed for the door.

It took Kurt a moment but then he followed and Sebastian offered a small smile before he followed after Kurt who had paused at the door to look at Blaine. He grabbed onto Sebastian's hand when he was close enough and Sebastian wasn't sure if Blaine had seen but he knew it didn't matter because he would still be feeling heartbroken.

"Meet up at Breadstix?" Rachel said as they walked down the hall.

"Yeah," Kurt said.

Sebastian stopped and Kurt stopped with him.

"Could you give us a moment," he said, "we'll catch up in a little bit."

Rachel looked between them and then she nodded.

He dropped into the piano bench, face in his hands, and his elbows supported by his knees. The entire day had been an emotional roller coaster and it seemed that he had gotten to the part where after climbing the highest peak he had to fall right back to the bottom. He was too late.

Kurt was dating Sebastian Smythe.

It was almost funny and Blaine was sure that someday in the future when he was over all of it, that he might look back and find the entire thing hilarious. All he felt at the moment was hurt.

Days of daydreaming about Kurt and their duet and getting so lost in thoughts of their kiss just to turn around and find out that Kurt wasn't even thinking about them, but that he had gone and moved on. He'd told Sam that Sebastian and Kurt looked too close, but Sam and Mercedes – come to think of it – had both denied it. But Kurt had chased after him and he'd kissed back.

All of it was a confusing mess and Blaine didn't know what he was supposed to do. He lifted his head and stood up. It was just a matter of continuing on like before. He would continue to see his therapist, move out of the apartment and back in with his mom, and keep working with the Warblers. He couldn't let Kurt and his choice of boyfriend bring him down and destroy all the work he'd done to make himself better.

He paced around the choir room for a minute and considered sitting down at the piano and singing, but stopped himself because he didn't know what kind of emotions would come out if he started to sing.

"Blaine, you're still here."

He turned and he was surprised to find Kurt standing behind him.

"I thought you were leaving," Blaine said and he didn't know what to think about Kurt standing in front of him.

"You wanted to talk to me," Kurt said, "and you're upset. I couldn't go before checking on you. Sebastian's waiting for me, but even he noticed you didn't look right."

Blaine looked away from Kurt and he gulped wondering if the pain he was feeling was how Kurt had felt when he spoke about Dave. Dave had been sweet and understanding and absolutely wonderful during the break up in a way that Blaine hadn't expected. He would never regret being with Dave.

"When did you and Sebastian start dating?" Blaine asked.

He heard Kurt take a few steps. "Not too long ago," Kurt said, "it was just something that happened. I, um, I really like him."

"Do you?" Blaine asked and scoffed, "well, I remember when he threw a slushy with rock salt and almost blinded me, and I remember when he photoshopped Finn. Not to mention all the non-family friendly texts he sent my way or all the flirting. All the times he asked me to cheat on you. Or how you disliked him and thought he was obnoxious and spoiled and an asshole or did you just forget all of that? Because that is who Sebastian is."

Kurt laughed and when Blaine turned to look at him, he was shaking his head and anger flashed in his eyes.

"You were dating the guy that made my life miserable," Kurt said, saying each word carefully, "the guy that threatened to kill me and that made me transfer schools. He's the guy that slushied me too many times to count and who forced a kiss on me. He's the guy who was so far in the closet that he had to pick on me time and time again. Or did you forget all of that."

Kurt was red in the face and he looked like he was shaking and Blaine wanted nothing more than to hug him and apologize, but he knew he couldn't.

"I forgave him," Kurt said, "but that doesn't mean I forgot what he did to me. That's the guy you were dating. You don't get to be upset at me for who my boyfriend is."

Then, Kurt turned and walked away and Blaine knew there would be no point in following after him. He had taken the wrong approach, but it was all too fresh. Kurt was dating Sebastian. It had bothered Blaine when he first found out that the two of them were friends, and knowing that they were dating was much worse.

He left the choir room, walking the hallways slowly, and making his way to his car. He drove straight to his mom's house and when he got there, he just walked up to his old room and dropped into the bed. It was once he was there that he started to cry.

Kurt thought that he did a good job of hiding his feelings through dinner and then when they went back to McKinley for the trans choir that Unique and Mr. Shuester had organized in order to teach Vocal Adrenaline a lesson.

"This is pretty cool," Sebastian said and he held Kurt's hand tightly.

Kurt knew that Sebastian had noticed how Kurt was trying his hardest to look like nothing was bothering him, and he appreciated how he hadn't asked him anything but instead just kept holding his hand and trying to offer his comfort.

"Yeah, it is," he whispered.

When it was all over and Mr. Shuester had quit his job and Vocal Adrenaline were being chased by Sue's hounds, Kurt said his goodbyes to everyone and left quickly with Sebastian.

"I don't want to talk about it," Kurt said as soon as they were in Sebastian's car.

"Okay," Sebastian said, "yours or mine?"

"I don't care," Kurt said, "as long as you stay with me."

Sebastian nodded and Kurt leaned his head against the cool glass of the car window. When Sebastian had convinced him earlier to check on Blaine, Kurt had been concerned that something happened to Blaine or that Blaine had shown up with the intention of discussing Blaine's break up, but he hadn't expected for Blaine to make the decision that talking about Sebastian was more important.

Kurt hadn't been able to help himself, at that point, and he'd had to let out his frustration for the relationship that Blaine had had with David Karofksy. It had been in bad taste, especially since Blaine and Karofksy had just broken up, but it had been the only thing that Kurt could focus on getting out because it was hard to talk about his feelings for Sebastian.

Sebastian drove them to his own house and he didn't say anything as he opened the door.

"Let's go upstairs," Sebastian said after he draped his coat over the sofa.

Kurt followed after him and when they made it up to his room the first thing Kurt thought to do was kiss Sebastian. So he did, pressing him against the door. Sebastian kissed back, gripping his hips and pulling him as close as possible.

His hands crawled under Sebastian's shirt and Sebastian lifted his arms and pulled away from Kurt long enough for Kurt to take the shirt off.

"Want to connect all the dots," Kurt muttered.

"Yeah, we're not doing that," Sebastian said with a smirk, "there's other fun things."

He pressed their lips together, walking Kurt backwards until they were just a few inches from the bed. After the one time after their first real date, they hadn't really done anything sexual, but Kurt craved and wanted Sebastian and he was ready for anything that he was willing to offer.

He let Sebastian pull his jacket off and then unbutton his shirt, shrugging it off his shoulders.

They fell onto Sebastian's bed and kept just kissing for a while, rutting into each other as they did. Kurt made the first move to take their pants off, popping Sebastian's button open and then opening his own and pulling them off his legs.

He groaned into Sebastian's lips when their cocks came into contact and moaned loud when Sebastian reached down between them to take him and himself into his hand, rubbing them together.

Kurt thrust into him and Sebastian chuckled before he surged them into a kiss again.
