"So this is your house?"

"Yeah," Alex shrugs one shoulder as he walks Celia into the kitchen, their fingers locked. "It's usually a little louder than this, but Sophie's at a sleepover and my dads are still at work. We've got it all to ourselves." He grins a little and kisses her, both of them tensing up a little. Their plans aren't exactly concrete; they'd agreed to just see how things went, but they've both brought protection. Just in case. They pull apart, a little flushed and breathless, and she swallows and glances around the room before walking into the living room.

"Aww, is this them?" she asks, her voice a little higher-pitched than usual, picking up a photograph. He smiles and follows her, perfectly happy just to spend the afternoon hanging out together.

"Yep. I mean, it's not like we just have pictures of other dudes making out on our coffee table." He notices her eyes narrow as she glances at the picture and then back at him. "It's him," he says, pointing at Kurt. "Check out the eyes."

She grins and nods.

"I was wondering. Not that it matters. I mean, they're both your- it's just, like, biology anyway. Who cares?"

"Don't worry. It's cool. Do you, uh- want a drink?"

She bites her lip and shakes her head, standing on tiptoe to kiss him again, smoothing her hands over his school blazer. His slide down to rest on her hips, and she giggles.

"Sorry-"

"Oh- should I not have- oh, God, am I being too forward? I'm so sorry, I just- I'm nervous-"

"Woah, woah, Alex," she brushes his fringe out of his eyes, "you've put your hands on my waist before. It's anything but creepy."

"Yeah, right, it's just- now we're- here. At my house."

"Uh-huh. Your house. Do you know where I'd like to be?"

He frowns.

"Where?"

"Your bedroom."

His eyebrows shoot up and his mouth falls open slightly, and he grins almost giddily as she takes his hand and heads for the stairs.

There's a creak. They both freeze halfway up the staircase.

"What was that?"

"I don't know. Everybody's supposed to be out."

They hear a laugh and frown at each other, puzzled, then there's a groan. Then a louder one.

"Oh no."

"Is that your dad?"

Alex screws his eyes closed.

"It's one of them."

There's another moan, slightly lower.

"And that's the other one."

Alex feels significantly less in the mood than he did a minute ago.

"Oh, cool! I want to meet them! Let's go say hi!"

"No-no-no-" he tries to stop her but her hand has slipped out of his and she's bounding up two steps at a time. "Celia, wait, you don't wanna-"

She puts on a light, breezy smile as she pushes open the door to the room with the voices, but Alex catches up just in time to see it disappear.

"Oh! Oh my goodness, I'm so sorry!" She backs out and stops on the landing, hands over her eyes. "They're- they, um. Oh my God."

"I tried to warn you. God, babe, I am so sorry you had to see that."

"No, I'm-" she can't finish the sentence. She stands swallowing for a moment.

"Sorry!" a voice shouts from the bedroom, "We didn't think anyone would be here!"

"Alexander, you are supposed to be at school!"

Alex pulls an indignant face and storms into the bedroom, not caring what he sees – it's nothing he hasn't walked in on before.

"And you're supposed to be at work! At least I had a free period! What's your excuse?"

Blaine bites his lip. Kurt's already standing, face bright pink, pillow over his crotch, and Blaine scrambles up next to him, dragging the sheet with him and wrapping it clumsily around his waist.

"Well, sometimes we just- both take the afternoon off and-"

Alex makes a weird noise.

"Aaaahhhh bleaurgh no no don't wanna hear it oh my god oh my god YOU ARE ADULTS oh god just- just-"

"Honey, sex is completely natural," Kurt assures, "it's nothing to be ashamed of."

"IT IS WHEN MY GIRLFRIEND WALKS IN ON YOU."

"Girlfriend?" Blaine asks, eyes wide. "That's Celia? We finally get to meet the famous Celia?" He starts to make his way to the door, but Alex (already taller than him) holds an arm out.

"Not until you put some clothes on. Both of you. Now."

Blaine's head falls, trying desperately to keep the smirk off his face.

"Right. Sorry. Sorry, Celia! We've heard so much about you!" he calls out. Alex breathes very slowly.

"Dads. Clothes. Please."

He turns and walks out, taking Celia's hand and walking her back downstairs without a word. Her hand is over her mouth now, her eyes wide and her shoulders shaking a little as she tries not to laugh.

"Alex, babe, it's really fine."

"No it's not. They're so fucking embarrassing."

"Honestly, I was kind of impressed. I mean, they're in their forties and still pretty flexible-"

"Oh my god-"

They reach the ground floor and she can't stop herself from sniggering.

"Sorry. But it bodes pretty well for you, if you think about it."

Alex wrinkles his nose, another similarity between him and the picture of his father. It makes her smile.

"I have. Literally. No idea how what just happened can possibly be construed as being a good thing."

"You told me they've been together for over twenty years. If they're still that crazy about each other- I just think you've got a pretty good example being set for you right there. It's something to aim for."

He's still not quite smiling, but the revulsion has died down a little. He links their fingers together.

"Twenty years, huh?"

She shrugs.

"Who knows? Although, I should probably take up yoga or something. There's no way I'd be able to get my legs that far back-"

"Gross. So gross," he says, dropping her hand and getting a soda from the fridge as she cackles, practically doubled over.

"Babe, I know he said clothes, but- we could still- you know…"

"Blaine! No-" he's interrupted by his husband's mouth on his neck, "I, hmmm… I guess… no! Honey, Alex just brought his first girlfriend home. We've got some serious embarrassing to do."

"Kurt, I think he's already maxed out."

"Yeah, okay, but I still want to meet her. Dressed. I promise we can finish this later." Blaine beams and pulls his shirt on.

"Are we allowed in?" Kurt asks from the other side of the living room door.

"Only if you're wearing pants."

"We promise."

"Enter."

They step inside cautiously, slightly forced smiles on their faces.

"You must be Celia," Blaine says, hand outstretched. "It's lovely to meet you at last. I mean, properly."

"You too," she says, shaking both Kurt and Blaine's hands enthusiastically. "Not that I minded that. I'm totally cool with it. With your whole thing."

"Which thing?" Kurt asks, brow furrowed with fake offence.

"Oh god, nothing. I just meant- god, I'm so sorry, I didn't mean-"

"Kurt, you butthead, don't be cruel. Sweetie, it's fine. So, what are you two doing home so early? Hope you weren't planning the same thing as us, eh?" he nudges Alex and winks. Alex and Celia tense up a little.

"Not necessarily, I mean, we just- had homework to do. Lots."

"Okay. Good. Homework is good," Kurt says, voice threatening to crack into a snort, "I hope our little display didn't freak you out, Celia."

"God, no. It was impressive."

She claps her hand over her mouth again. Alex can't help but feel a little smug that he's not the only one who's mortified. Kurt and Blaine grin and give each other a high-five.

"Thanks," Blaine says, "well now that we're all here and suitably not in the mood, how about we go and cook dinner. Celia, how do you feel about enchiladas?"

"She loves them," Alex replies for her, suspecting she won't be up to talking for another couple of minutes. She can't quite bring herself to look at them and chooses to bury her face in Alex's shoulder instead. Kurt and Blaine smile at them and make a swift exit, closing the door behind them. They can't help but catch a glimpse of the way he looks at the girl, a warm smile playing on his lips.

"I like her," Blaine says as he reaches for the tortillas. "She seems sweet."

"Not as sweet as you," Kurt responds, taking a moment to wind his arms around Blaine's waist and kissing the back of his neck, "but yeah. She's lovely. Did you see Alex's face just now?"

"Mhmm. Gave me high school flashbacks."

"Gave me ten-minutes-ago flashbacks."

Blaine glances to the side at the mirror on the wall so he can see Kurt without turning around. They smile softly, easily at each other. They'd joked about being embarrassing dads, but neither of them had seen this coming. Even though they probably should.

"We're gross."

"The worst. Now," he adds with a slap to Blaine's ass, "get moving with my dinner or I won't finish what I started."

Blaine pouts for a second before the smile comes back.

"What I let you think you started. Go chop some peppers."
