"We're home!" Santana called, offloading her heavy paper bags into the armchair and kicking off her shoes, leaving Rachel to place them in the rack and heading into the kitchen to find the Diet Coke. She turned to find Kurt snuggled up to Blaine on the sofa, shirt rolled up over the swell of his belly, Blaine's hands spread wide across the stretched skin, both of them smiling with eyes soft and hair awry and Kurt's neck patterned black and purple. "Oh Jesus, Kurt, what happened to your neck? Did he hang onto it like a dog or something?"

Kurt just smiled at her, nuzzling into the crook of Blaine's neck as Blaine raised Kurt's left hand to his lips and pressed a kiss to his third finger, the fingers of his other hand drawing delicate circles across the thin skin of Kurt's bump. Beaming, Rachel dropped her collection of bags onto the floor, clothes spilling out that Quinn tutted over and bent down to refold and organise, ignoring Kurt and Blaine in favour of cooing, "How are my favourite niece and nephew?" to Kurt's bump, batting Blaine's hands aside to walk her fingers over the prominent swell.

"Rachel, honey, not to be a killjoy, but I think Blaine gets to touch my belly, as the father," Kurt said affectionately, pushing Rachel gently away and lowering Blaine's hands back down, cheeks flushed with pleasure and helpless smile lighting up his eyes. "You can still talk to them, but no singing." Rachel pouted, but sat down on the floor next to Kurt's legs, laying her head on his thigh and murmuring nonsensically to the babies.

"So this is it?" Quinn asked, collapsing on the sofa next to Blaine and easing her heels off, grabbing the TV remote and flipping over to the episode ofFriendsthey'd been watching before the three women had left for bagels and the siren call of stores. "Are you guys back together? Did Puck punching Blaine in the face pay off?"

"We're back together," Kurt confirmed sweetly, lacing his fingers through Blaine's and curving their hands over his belly, caressing slow and gentle. "We're back together and having twins and we're going to be a family."

"We really are going to have to start looking for a bigger place then," Santana observed reluctantly. "Especially with everyone treating us like unpaid psychiatrist's and this loft like a place where they can crash for the night without even asking for permission." She saw Rachel and Kurt exchange an incredulous look over her head and added, "But you guys are my family, so I get rights above everyone else."

"We're all a family, Santana," Rachel reminded her, collapsing next to Quinn and picking up a bag, going through her purchases with a smile on her lips. "A messed-up, bitchy, incestuous family, who should never have a rule of not speaking to each other's exes because no one would be talking right now."

A knock came at the door, and all five of them looked up to see Adam in the doorway, grinning and bearing cartons of take-away Chinese. "Room for one more on that couch?" he asked cheerfully, and Santana beckoned him in with one crooked finger, shoving Rachel's bags to the floor to a squeak from the shorter girl and brushing a pile of magazines interspersed with choreography notes and sheet music aside to make room for the food.

"You bring food, you can have the armchair to yourself," she announced grandly, gesturing to the chair with a flourish, and Adam laughed and brushed a kiss to the top of her head as he sat down, crossing one leg over the other and smiling as Quinn handed him a mug of coffee, a flush nestling high in her cheeks that had Santana turning and winking at Kurt, waggling her eyebrows mischievously.

"Oh, sorry, I should introduce you," Kurt said suddenly, rolling his shirt back down over his stomach and easing himself into a proper sitting position. "Adam, this is Blaine, who you already know all about. And before you get all overprotective, we talked and made up and we are back together and ready to have these babies. Blaine, this is Adam, who doesn't live here but makes it seem like he does half the time."

"Right, so Puck punching the poor guy in the face wasn't worth nothing at least," Adam observed, and Kurt shrugged and smiled, kissing Blaine's cheek, a yellowing bruise painted into the flesh. "I have to ask though, Blaine, why did you leave when Kurt first told you?"

"Oh, Kurt is very bad at specifying which we he means lately, and Blaine thought he meant you were the father, not him," Rachel said airily before Blaine could answer, and Adam's jaw dropped, making Santana laugh as she wriggled into a more comfortable position on the couch and balanced her noodle on her thighs.

"But that's absurd!" Adam exclaimed. "Kurt and I never did anything below the neck apart from hold hands, as if we ever had sex. I knew that it wasn't mine the second he ran out of class to throw up." Laughter rang out through the loft, and Blaine shrank uncomfortably into the sofa, clinging to Kurt's hand as the conversation continued over his head, familiar and easy and shutting him out.

It took an hour for him to be able to creep into the bathroom for even two minutes to brush his teeth, listening to Rachel and then Quinn singing loudly, Santana and Adam laughing raucously and the clink of wine glasses in the living room, and feeling alone in a place everyone always said was welcoming, but where he felt like the only thing to cling to was Kurt, and even he was talking over his head, laughing and chattering and flirting with Adam even with Blaine pressed against side and Blaine's hand cupped against his bump, keeping their children safe and warm.

Kurt was asleep when he got back into his room, face peaceful and a smile tugging at the corners of his mouth, body lax and beautiful against the sheets, a flush in his cheeks and his eyelashes dark and fanned out against the petals of pink. Stripping down to his T-shirt and boxers, Blaine sat on the bed next to him, gazing at him with sad eyes, because he still felt far away even with them back together, and he'd never wanted it to be this way. Leaning over, he carefully rolled the hem of Kurt's shirt up a little higher and pressed a line of kisses to the exposed skin of his swollen belly, whispering, "I love you," to the babies growing within him before sliding up and pressing his lips to Kurt's slack, unresponsive ones, repeating, "And I love you. Somuch," before rolling onto his side, facing away from Kurt, and burying his face in a pillow, concentrating on counting backwards from one million to stave off the tears until sleep finally fell over his restless body.

Morning came in a blaze of sunshine and loud traffic outside, waking Blaine from sleep. He sat up to see Kurt slumbering next to him, his arms wrapped around his pillow and his cheek pressed against the cotton. Blaine ran a gentle hand over the swell of Kurt's bump, and Kurt shifted towards him, murmuring, "Love you, Blaine." He sniffed hard, blinking back tears, and leaned over to press a soft kiss to Kurt's temple, standing up and wrapping a robe around himself.

When he padded through into the living room, he found Adam watching the news and almost retreated back into the bedroom. "Morning," Adam said cheerfully, turning to give him a grin. "Rachel and Santana are both still in bed, Quinn went out for muffins and coffee since all they have is muesli and decaf."

"Great," Blaine said monotonously, trying not to let images of Kurt and Adam flit across his mind, imaginings that had haunted him through the silent nights, waking him with a cold sweat clinging to his skin and bitter tears burning at his throat.

"I know you don't like me, you have every right not to," Adam said as easily as if it was the weather report. "I was dating Kurt, you thought that we were having a baby together, you thought he'd moved on and forgotten you. Kurt never stopped thinking about you, I promise you that. Every other sentence was an anecdote about you, he would unintentionally compare us, he fantasised about you two singingCome What Mayat your wedding when I was right next to him. He always loved you, he just needed a little time. It's a big city out here, but all he wants here is you."

The curtain obscuring Kurt's bedroom from the rest of the loft swept aside and a sleepy-eyed Kurt wandered out, eyelids heavy with lingering sleep. "Morning honey," he murmured sweetly, pressing a soft kiss to Blaine's lips and wrapping his arms around his waist. "I don't even remember you coming to bed last night, I must've fallen asleep." Blaine nodded softly, tilting his forehead against Kurt's and kissing him, fingers digging possessively into his waist, a thrill shooting sharply through him at Adam seeing this, seeing that Kurt was his and only his, no one else's, hoping he would connect these kisses to the night at the wedding, imagine Kurt in bed with him, spread out and helplessly wanting and begging for Blaine.

"Oh, Kurt, let me show you the apartments Santana and I found last night," Adam said, opening the laptop lying closed and charging on the coffee table. "They're all further into the city, closer to the train station and the airport for when you guys have visitors, closer to NYADA and to my place and all really good prices for what you'll be getting."

Kurt left Blaine's arms, his warmth and scent fading, and sat down next to Adam, the laptop balanced between their thighs and Adam's arm hooking around Kurt's waist as he excitedly said, "Ooh, four bedrooms, that means there's an extra room for the babies when they get too big to sleep in the same room as me and Blaine!"

"I called the couple selling it last night, they're moving to more of a family place and they thought you sounded like a wonderful bunch of people," Adam explained, pressing an affectionate kiss to Kurt's cheek. "I could take you and Santana to look at it later if you like, Rachel has a singing lesson and then she's lunching with her mother."

"Oh, that'd be great, especially since I'm having the worst craving for pizza and that amazing place with the crunchy thin crust is in the same part of town," Kurt declared, Adam laughing and reaching for the phone to book a viewing of the apartment. "You want to come too, sweetie? You'll be paying a quarter of the rent, after all."

"It's fine, you three go and check it out, I'll just get used to this place first, so I can remember the first place I lived in in New York," Blaine said, and Kurt gave him a sunny smile before turning back to the apartment listings, curling closer to Adam, and sadness arced through Blaine as he turned into the bathroom, tortured by images of Kurt's head rising, rising from Adam's shoulder to press their lips together, kisses slow and sweet and luxurious, turning into lost clothes and close, writhing, naked bodies, someone else bringing their name spilling in an ecstatic scream from Kurt's lips.

They ended up getting the apartment, and it was ready for them to move in a fortnight after Kurt arrived home giddy with excitement from seeing it for the first time, Adam's arm steadying him as he went on and on about how beautiful the place was, waving his hands to better illustrate his point. The moving men arrived at ten to take apart and box up all their bigger belongings such as the beds, couches, bookcase and table, leaving them to finish cleaning up and leaving the apartment in the same state they would've wanted to move into almost a year ago.

Rachel, with her hair wrapped in a scarf to protect it from dust and wielding the vacuum like it was a weapon, told Blaine to wash the windows while she vacuumed, Santana dusted and disinfected, Adam repainted scuffed corners and paler corners from their posters and Kurt mopped the floor, shoving the bucket around with his foot and grumbling about how he could help more if they'd only trust that he was perfectly fine even with his growing bump.

"I'm pregnant, I'm not an invalid," he finally snapped angrily, and Blaine hid his adoring grin in the window lest Kurt think he was making fun of him and get mad again. The last few weeks had been a particularly trying time with Kurt's mood swings, and he was liable to get angry over the slightest motivation, and tearfully apologise half an hour later.

All of the other four of them wheeled around at a yelp, and Blaine immediately jumped down from his stepladder when his eyes alighted on Kurt on the ground, panic rushing through him. But Adam was there first, babbling worriedly, and Kurt just shook his head at him and took the proffered hand to help himself up. "Calm down, I just slipped, I'm fine," he reassured Adam gazing up into his eyes and squeezing his hand. "Honestly, Ad, you worry too much. I feel sorry for whoever you end up having kids with, you'll be the worst kind of neurotic father."

Someone nudged Blaine in the side, and he turned to find Santana next to him, spinning her feather duster in her hand and shooting a glare to the two men, still standing far too close for Blaine's peace of mind. "If you don't start getting in there, Anderson, Doctor Who is going to spirit your boy away again," she hissed to him. "Adam's lovely, mostly, but he just doesn't know where to draw the line with the flirting and Kurt is a natural-born flirt. He's flirting with me most days, he just doesn't realise it. You gotta start laying down the law. It's just a kiss here, a touch there, flirting and subtle caresses and maybe letting him hear you guys with your kinky sex life occasionally. It's not hard."

With sudden determination in his veins, Blaine strode across the room and drew Kurt into his arms, pecking soft kisses over as much of his face as he could reach, smiling when Kurt giggled and squirmed playfully in his arms, hands cupping Blaine's face gently and eyes alight with love. "Are you sure you're okay?" Blaine asked softly, pressing a hard, slightly rough kiss to Kurt's lips that left the beautiful man opposite him breathing heavily, slightly flushed and with lust-darkened eyes when he pulled away.

"Mm, back's a little sore, one of the babies seems to think my spine is a climbing frame," Kurt murmured with a delicate giggle. "Maybe I can take advantage of your magical hands once we're at the new place?"

"It's a date," Blaine promised, tangling their fingers together at their sides. "I'll even tip the moving men to rebuild our bed first." Kurt laughed and kissed him softly, leaning their foreheads together and swaying slightly in his arms.

Kurt fell asleep in his arms that night, loose and pliable from a massage, but Blaine still couldn't shake the feelings that there was more to his relationship with Adam than he was seeing, and the desperate need to know for certain if he was being irrational or if his pregnant boyfriend was cheating on him plagued at him throughout the night, and he didn't fall asleep until the grey light of a new dawn was creeping across the room.

"I just don't know how I'm supposed to put it out there that Kurt is my boyfriend and that's not going to change without obnoxious public displays of affection, and I don't want that," Blaine said as he and Santana climbed the stairs back to the apartment. "Kurt's special, he deserves more than me kissing and groping him to try and stake my claim."

"Just act more like his boyfriend, you guys were so touchy-feely before you broke up, and after, but now you're treating him like he actually is made of porcelain," Santana advised gently. "If you're making him uncomfortable he'll tell you, he's not some damsel in distress. And I can see that he wants to kiss you constantly as much as you want to spend every waking moment attached to him at the mouth."

Blaine smiled gratefully at her and opened the door to his arms suddenly full of flushed, overexcited boyfriend, the swell of his belly pressed against his stomach and his chin tucked securely over Blaine's shoulder. "I found out the sex today," Kurt said, bobbing on the balls of his feet and beaming. "Can I tell you? Do you want to know? Don't make me keep it a secret!" Grinning, Blaine nodded and Kurt took his hand, laying it over the left side of his belly. "This is a boy." He moved Blaine's hand over to the right and concluded, "And this is a girl."

"One of each?" Blaine breathed disbelievingly, massaging both hands over Kurt's belly, and Kurt nodded enthusiastically, eyes shining with tears of joy and smile wide. "Oh my God, that's...this is perfect." Blinking back tears, Blaine beamed at Kurt and breathed, "I love you so much," before kissing him, arms sliding around Kurt's waist as Kurt's wrapped around his neck, pressing them so close they were breathing in the scent of each other's skin, and Blaine heard Santana clear her throat demonstratively, winking at them when Kurt broke away with a secretive smile playing around the corners of his mouth, a tear clinging to his eyelashes.

"I love you too," he murmured, wiping his tear-filled eyes with the back of his hand, and Blaine pressed a kiss beneath his eye where the tear was slowly slipping over his skin, trailing his lips down Kurt's face before reaching his mouth again, laying a hand curved neatly over the side of Kurt's bump as they kissed.

The door slid open and Rachel bounded into the apartment on her trainers, hair pulled back and smiling widely. "The gym around the corner from Adam's apartment is amazing!" she shouted, grabbing herself a bottle of water from the fridge and taking a long drink. "And there was this really cute trainer who was totally flirting with me."

"So, did you find out the sex of the babies?" Adam asked cheerfully, pecking a kiss against Kurt's jaw that sent a thrill of jealousy through Blaine and had his hands tightening on Kurt's waist, pulling him against him and wrapping a hand possessively over his belly.

"We did," Kurt answered happily, nuzzling back against Blaine's neck and twining their fingers together over his bump. "It's a boy, and a girl." He turned his head back to kiss Blaine, sweet and soft, and Blaine smiled against his mouth at the idea that Adam would be standing in front of them, waiting to be hugged, and Kurt was too busy in his arms to be distracted by someone else.

"We should go out tonight and celebrate!" Rachel called, rushing over to wrap both Kurt and Blaine in a warm embrace, kissing Blaine's cheek and rubbing a hand over the swell of Kurt's belly. "No, wait, I have an idea! Me, Santana and Adam will go out, find a club and dance with strangers and enjoy ourselves, you two can stay in for a nice couple's evening in, just you two."

"That sounds great, we haven't spent an evening with just us in a long time," Kurt said, looking up suggestively from beneath his lashes. Blaine grinned and mouthedThank youto Rachel as Kurt pressed a kiss just beneath his chin.

The night was perfect, until Kurt's phone started ringing midway through a long, deep kiss and he leapt to answer it. "Hi, hi Ad," he said breathlessly. "Sounds like you're having fun out there. Hope you meet someone. Yeah, we're having a nice time here. It's perfect. Yeah, I'll show you the sonogram pictures tomorrow. I can't wait to talk baby names."

"We need to talk, Kurt," Blaine said when Kurt hung up, flushed and grinning. "It's great that you've made another friend here, but it worries me that you're paying more attention to your relationship with him than your relationship with me. You're telling him things about the twins before you tell me, you're taking him to appointments, you're choosing what colour to paint the nursery, you're visiting apartments where we're going to raise our children, you're taking his calls during a night that's supposed to be about just us. It's making me think that maybe there's...more to your relationship than you're letting the rest of us see."

"Are you suggesting that I'm having an affair with Adam?" Kurt asked, voice edged with danger. "When we've only just reconciled? When I'm having your children? I'm not worried about our reconciliation, and I don't have to sleep with someone else because I'm insecure about our relationship! I'm not you!"

It took a moment for Kurt's words to sink in, then Blaine stood up, the candles and half-eaten dinner and blankets around them forgotten, swept away as if their supposedly romantic evening was no more than dust. "Maybe I am insecure about what we have," Blaine said, lower lip quivering with an onslaught of coming tears. "But it's you who makes me insecure."

"Blaine, please, I'm sorry, I didn't mean it like that," Kurt pleaded, eyes wet with tears, struggling to get himself up from the floor and follow Blaine. "I'm sorry, don't leave, tonight was supposed to be about us, I wasn't thinking when I picked up the phone and I'm sorry,please."

"You weren't thinking," Blaine snapped, stepping into his shoes and watching the heartbreaking sight of Kurt trying to stand up to follow, stuck on the ground with the bulge of their children growing within him. "You don't think about how I feel. Ultimately, Kurt, that led to us breaking up in the first place."

The door slammed loudly behind Blaine with a sad sense of finality. He left the apartment block, wrapping his arms around himself, the way he had early in the morning almost a year ago, leaving Kurt slumped on the floor of the living room, surrounded by the remains of a romantic evening in, sobbing into his hands.
