"But really, Kurt? The perfect guy?" Sebastian looked relaxed and content, his lips very swollen from their extended make-out session.

Kurt snuggled closer to his boyfriend. "Perfect for me. You are so amazing. I just love spending time with you."

Sebastian still didn't look too convinced. Kurt looked over at the wall for other ways to explain it.

"Nobody I know would have laughed as hard as I did at the twisted humour of'The Book of Mormon' with me. Not Rachel, not Mercedes..." Kurt thought a second. "Well, maybe Sam would though...and maybe Puck."

Seeing the unimpressed looked on Sebastian's face, Kurt rushed on. "And nobody else I know is as tall and gorgeous as you." Kurt nodded confidently. "Well...except Sam maybe... He's done some modeling, you know. And Puck looks pretty amazing without his shirt on."

Sebastian was giving him a disbelieving look. Kurt reined in his rambling mouth. It was late and he was obviously saying far too much.

But then Kurt rushed on again, wanting to finish making his point. "Nobody else speaks French..."

"If you mention any other men, I'm calling this whole thing off." Sebastian interrupted, jokingly. He sighed. "I know that we are very compatible. But I'm still kind of fucked up. Hardly perfect, Kurt."

Kurt gave him a hug. "Thank god you have a flaw or two, or I'd probably think you were totally out of my league."

Sebastian let out a deep breath, seeming to relax even more. "I feel so incredibly happy right now, Kurt. I've been so worried about us, our relationship, since New Years. Since the start, really. Worried that I won't have what it takes to make a relationship work. Worried that I won't be a good boyfriend for you."

"Is that what was happening when you wouldn't talk to me after our fight?" Kurt had wondered about this for so long.

Sebastian sighed. "I started to feel like you were pulling away from me, and I was worried that you were losing interest in me. That you'd come to your senses and realized I wasn't worth the trouble of dealing with all my shit. That it would be easier for you to be with someone like Blaine. Seeing you with him..." Shaking his head, Sebastian ran a hand through his hair. "…it scared me so much. I think I avoided you after that because I thought you might break up with me, make it official. I didn't know how to talk to you about my feelings. I felt a bit overwhelmed, a bit out of my depth."

"Then, when you sexted me, it was something I knew." Sebastian gave Kurt a half-hearted smirk. "I could be your hook-up guy, no questions asked. And I was so desperate to see you, touch you..." He shrugged, looking young.

Kurt nodded, understanding more about his side of things now. It was sometimes hard to see beyond Sebastian's confident outer shell and remember that he was still new to relationships, and wasn't always in touch with what was happening. Kurt would need to talk to him more, push him to get into the habit of being more open with his feelings.

"Overall, you have been great. I think what really screwed things up after the holidays was how busy we got, and not keeping up with each other enough." Kurt said softly.

Sebastian sighed. "Well, we are both hard working people, so we will need to figure out how to balance everything."

Kurt's glance fell to his key on the coffee table. And an idea hit him. Was it too much? Too soon?

"Um, Bas...I had an idea. Tell me honestly if you think it's too much." Kurt bit his lip.

Sebastian's eyes widened, looking curious. "What is it?"

Taking a deep breath, Kurt let it out slowly. "I'm going to make the suggestion, but I don't want you to give your final answer to it right now. I think it's something we both need to think over for a few days. Ok?"

Sebastian nodded, clearly listening attentively.

"Matt's moving out next week, and I haven't found another roommate. Maybe you could move into his room?" Kurt put his hands up, preventing Sebastian from saying anything. "Just let me say what I'm thinking... I think it would be good if we had our own rooms to retreat to, if we need some space. It would be much easier at night. No late night subways or taxis. And we could just try it for the summer, see if we're good together. You could even sublet your place, or keep it...I know this is a big step. Blaine and I moved in together too quickly and it was really bad for our relationship in the long run."

Sebastian was nodding, but he looked happy. He squeezed Kurt's hand. "You really wouldn't mind me leaving your bed every night to sleep on my own?"

Kurt hugged him. "No, I can deal with it. And living in the same apartment will make it so much easier. Plus, this way, we can cuddle together in the mornings, which you know I love so much."

"I think living together will be good. We can hang out together for meals and studying. Less travel time. More sex." Sebastian gave Kurt a little smirk.

Kurt returned it, pleased that Sebastian seemed so on board with the idea. "Bas, this is great, but I'm so tired. I'm afraid to look at the clock." Kurt sat up, yawning. "Why don't you go sleep in Matt's bed? The sheets are clean. Consider it a test run for maybe moving in here."

Getting up from the sofa, Sebastian pulled Kurt to stand up. He did look really tired. "OK. I love you, Mon petit Chou." And after a long good night kiss, they headed for the separate bedrooms.

"Did I tell you about Bianca's news?" Sebastian wrapped his arms around Kurt's waist, pulling him close.

Kurt stretched up to plant a kiss on his handsome boyfriend's cheek. "No, what?"

Sebastian smiled, looking happy and excited. "She's moving to New York for the summer to work on a case. Kind of a trial run to see if she wants to transfer here permanently."

Waving around the empty bedroom, Kurt chuckled. "Does she need a place to stay?" It was May 1st, and Matt had moved out earlier. Kurt was sweeping the floor.

Sebastian gave him a teasing grin. "Well, as long as your offer is still open, I thought she could stay at my place and I could move in here."

Dropping the broom, Kurt hauled Sebastian down to kiss him properly. Thoroughly. Until Sebastian was groaning and grabbing Kurt's ass, lifting him until Kurt wrapped his legs around Sebastian's waist.

Kurt giggled as Sebastian walked quickly over to Kurt's bedroom and dumped them both onto the bed. But it didn't take long for his happy giggles to turn into deep moans, as their clothes came off and their kisses intensified.

Sebastian had his arms wrapped around Kurt loosely, and was running his hands back and forth along his silky skin. Cuddling in bed naked with his hot, incredible boyfriend was definitely one of his favorite things to do.

Kurt was sleepy, but he had to bring something up that had been nagging at him. "Bas, I know we've had a rocky few months, and I don't hold anything you have done against you. But could you go get tested soon? I'd like to go back to not using condoms again."

Sebastian's eyebrow tilted up. "And aren't you going to get tested too?"

Kurt shrugged. "There hasn't been anyone else since you." As if he could even have been interested in anyone else when they had been apart. Plus he looked like a walking skeleton back then. Not exactly appealing.

"The same for me.." Sebastian was smiling broadly.

Kurt scrunched up his eyebrows. "Then why the condoms lately?"

Sebastian let out a sigh, fidgeting with Kurt's hand. "You were the one singing duets with your ex and not telling me about it. You were the one hugging cute men in cafes." He shrugged. "You are gorgeous and talented. You don't seem even to notice how many men are into you. Even during that role play at Scandals, there were three other guys edging closer to you by the time I walked to the bar."

Letting out a surprised laugh, Kurt cuddled into Sebastian. "Blaine is just a friend and classmate now and I'm so, so sorry I didn't tell you about that duet. The guy in the cafe was my roommate Matt, and I was hugging him to congratulate him for deciding to move in with his girlfriend. And I don't even notice other men paying attention to me, because I only see you."

That comment set off another intense make-out session.

"Wait, wait…." Kurt pulled back for air, and jumped out of the bed.

Sebastian hooted at him as he ran naked to the living room and came back, jumping under the covers again, a big smile on his face.

"Close your eyes and put out your hand, Bas." Kurt's eyes sparkled up at him, and Sebastian was smiling as he followed the directions.

Kurt placed his key on Sebastian's palm. "OK, you can open your eyes now."

Looking down at his palm, Sebastian smiled at seeing the key there. When they had exchanged keys last fall, it had been a big step. A sign of trust and their deepening relationship.

But this time it meant even more. This was Kurt inviting Sebastian into his personal space. To share the apartment, but also to share so much more. To share their lives. Kurt was giving him the key, letting him in. Sebastian had to be just as open with Kurt, let him in all the way.

Looking up at Kurt, he knew his eyes were brimming with tears. "Are you sure, Kurt? Are you really sure you want to live looking at this smirky little meerkat face every day?"

Kurt chuckled, and then curled Sebastian's fingers over the key. "Yup, I happen to be in love with the owner of that face. And I want to see your smirk every single fucking day."

Chuckling, Sebastian leaned closer, smirking until their lips touched, and sinking into a deep kiss.
