From a prompt on the Glee Kink Meme:

Sam is thirty and married with kids. He's...well, he might not say "happy" with his life, but he is content.

That is, until he meets his kids' babysitter Blaine.

Blaine, who is seventeen years old and quite possibly the most beautiful person Sam has ever seen. He didn't even know he LIKED guys until then, but he can't stop thinking about Blaine, and his beautiful eyes and smile (and his ass...) He also can't help but notice the way Blaine looks at him when he thinks Sam's not looking.

Sam has to at least try to push the thoughts to the back of his head, but all effort goes out the window the night that Sam finds himself alone in the house with Blaine there, his kids asleep, and his wife nowhere to be seen (maybe during a snowstorm? Sam's wife decides to stay at her friend's, and Sam isn't comfortable letting Blaine drive in the snow.) Sam and Blaine get closer, and they realize how badly they want each other, and they wind up having sex.

And Sam promises himself that will be the only time, but then it happens again. And again, and again.

(Optional: At some point in their relationship, Sam discovers Blaine has a daddy kink, which Sam is all too happy to oblige.)

"What would you rather be, dad, a t-rex or a brachiosaurus?" asked the little girl sprawled out on her parents' bed.

"Honey, could you zip me?" asked the woman at the mirror.

Sam zipped Quinn's dress while answering Matilda's question. "Brachiosaurus, obviously."

"Why? They weren't even meat eaters."

"No, but they were huge." He stood over Matilda, pretending to be menacing. She fake-screamed and he scooped her up. "A brachiosaurus could totally win a fight with a t-rex just by stepping on it."

"Dad!" Matilda rolled her eyes at him. Somehow it was cute when his five-year-old daughter did that to him. "They weren't even alive at the same time!"

"Oh, how silly of me!" He set her back down on the bed. "I guess I better go pick up Tina," he said to Quinn.
"You wanna ride along, Tillie?"

"Only if I don't have to put on shoes."

"It's twenty degrees outside," Quinn said. "You're not going outside without shoes."

"Then no thanks," Matilda said before she walked casually out of the room.

"Okay, back in about twenty minutes," Sam said, giving Quinn a peck on the cheek.

"Okay." Quinn called him back when he was half-way down the hall. "Sam! Wait!"

He walked back to the bedroom door. "Yeah?"

"I almost forgot. Tina has mono. She recommended a friend of hers named, um...Blaine."

"You want to leave the kids with someone we've never met? I don't know, honey...Maybe I should stay home with them instead."

"You can't stay home, Sam. It's my firm's Christmas party. If I show up without my spouse the partners will think..."

Sam waited, but she didn't finish. "The partners will think what?"

"It's important, honey. Please. Besides I talked to Shirley and she said the boy is very responsible."

A boy? Well, it wasn't that weird. Sam was good with kids when he was a teenager. Maybe this kid had younger siblings too. And he did trust Tina's mother, and the party was important to Quinn.

Tina lived in the wealthier part of town, the part Quinn really wanted to move to as soon as she made partner. This Blaine kid, as it turned out, lived right next door to her. Sam chuckled at the thought that Tina probably was the type of girl who would fall in love with and marry the boy next door.

Oh! But...Tina had mono! Sam didn't want to risk this guy giving mono to his kids, especially Willa, who was just a toddler, after all. So if there had been any kissing, any kissing whatsoever between Tina and this boy-next-door, then no way. He would stay home no matter what Quinn said.

He pulled his car up to the curb in front of the house next to Tina's, and he called her. After a few rings he heard a weak "Mr. Evans?" She sounded horrible.

"Hi, Tina! Sorry to bother you when you're sick."

"'Sokay," she said unconvincingly.

"I just need to ask you a quick question about...about this Blaine person."

"Oh, he's a really nice guy. Very mature."

"Yeah. Yeah, I'm sure he is. I just have to ask, and you know I don't want to pry into your personal life, but you do have the kissing disease..."

Tina laughed. "You're asking if I've kissed Blaine?"

"Well..."

"No. He's totally gay."

"Oh!" Sam wondered if Quinn knew this. He suspected she might not be thrilled about it. "Do, uh...does your dad know?" Tina's father was one of the partners at Quinn's firm, and if he was okay with Tina hanging out with a gay kid, Quinn wouldn't complain.

"Um. I think so? I can't remember him ever hiding it, so..."

Well, that would have to be good enough. "Okay, thanks. Sorry again to have bothered you. Get some rest!"

So he would give the kid a chance. He jogged up the long walkway to the front door and rang the bell. The door opened, and there stood the most beautiful person he had ever seen. He stood there, stunned, taking in the soft curls, the golden eyes, the transcendent smile...and it took him a moment to realize that this gorgeous person he was probably gaping at like an idiot was a teenage boy. A teenage boy who was saying his name, apparently not for the first time: "Mr. Evans?"

"Yes! Yes. Blaine?"

"Yes." Blaine smiled at him and it killed him.

"Well, are you ready?"

"Yes, but..." Blaine already had a coat and gloves on, so Sam worried about the "but."

"But?"

Blaine looked down as he said, "My mom would like to meet you first."

"Oh! Yeah, of course. I understand, I'm a father too." Duh. Obviously.

Blaine gave him that smile again and stepped back from the door to let him in. Sam wiped his feet really thoroughly on the doormat before walking in, even though it wasn't muddy or anything and he didn't think he stepped in anything. Blaine led him into the living room, and he had the very weird feeling of being a teenager again, about to meet his date's parents. What the hell? But then he realized it must be because Blaine's family was rich. He was always a little nervous-well, a little uncomfortable-around rich people.

But if he had learned one thing from Quinn in their eight years of marriage, it was how to act confident, even when he had to fake it. He strode into the room, smiled at the woman sitting there, and extended his hand. "Sam Evans. My wife Quinn works with Ray Chang next door. It's a pleasure to meet you, Mrs..."

"Anderson," she said, standing and shaking his hand. "But call me Margaret."

"Margaret," Sam repeated with a nod. "Tina usually sits for us, but she's sick tonight. We've heard great things from her about your son, though, and we really appreciate him being available on such short notice."

"Yes, well, Blaine doesn't go out much. Except with Tina."

"Mom!" Blaine was actually blushing, and Sam caught him peering up at him through the thickest eyelashes...

"What? You don't want your employer to think you're a hard partier."

"The event my wife and I are going to might run late," Sam said. "I hope that won't be a problem."

"No, of course not. Blaine's a big boy, old enough to stay up late."

"Oh, God, mother."

Sam looked at his watch. "Well, we really need to get going. My wife doesn't like to make too late of an entrance. It was great meeting you."

Margaret Anderson just smiled at him, so he turned to leave, and Blaine did too. "Try not to make too much noise when you get home, Blaine," she called after them.

"So..." Sam said when they got into the car. God, he couldn't believe he was nervous and tongue-tied around a teenager. A teenage boy. "Are you and Tina in the same grade at school?"

"Yes, sir. But, not the same school. I go to Dalton, in Westerville."

Sam laughed. "You don't have to call me sir."

"Sorry. It's habit. It's required at my school."

"What kind of school is Dalton?"

"It's an all-boys boarding school, sir. I mean, Mr. Evans. I'm just home for the weekend."

"Oh, that's too bad. For Tina, I mean. Since you're friends."

"She has plenty of friends at McKinley."

"Sure, of course. And you must have plenty of boyfriends at Dalton."

"Sir?"

"Friends, I mean! You said it's an all-boys school, so..." Sam fiddled with the heat controls.

"Did Tina tell you that I'm gay?"

"She did, but that's not...It's fine with me. Not that you need my permission, of course, I just mean that it doesn't bother me." Wow, did he sound like an idiot. He decided to shut up for a while so Blaine wouldn't think he was a complete moron.

He found himself checking the passenger's side mirror a lot during the drive back to his house. And noticing that Blaine, in profile, was gorgeous. Gorgeous was not a word he had ever thought before to describe a man. A boy. A minor, for God's sake.

Thirty was too young to be having a mid-life crisis. Wasn't it? What the hell was wrong with him?

Wait, Tina was a senior in high school, right? And some high school seniors were eighteen. Some were older, of course, but he couldn't imagine that Blaine would have been held back. How to find out...

"So are you eighteen?" Oh, clever.

"Not yet, sir. My birthday is in April."

"Really? Mine is in May." Okay, time to shut up again.

He glanced over at...well, in the direction of the passenger's side mirror again, and this time he caught Blaine looking at him. He gave him what was probably a really dopey grin, and Blaine smiled back at him. And Blaine's smile was just...well, he was back at the word gorgeous again. And the boy blushed again, and Sam had to wonder...Well, he was gay, and Sam was told he was good-looking...It was how he'd convinced Quinn to go out with him in college, and even though she said she loved him for more than his looks, he sometimes had his doubts.

Quinn and the girls were in the kitchen when he got home with Blaine. He rested a hand on Blaine's shoulder when he introduced him-he hadn't done it intentionally, and his first instinct when he realized what he'd done was to pull it away quickly. But he didn't. He reasoned that pulling it away would have been odder and more awkward than the original gesture, which no one seemed to think twice about. And that was probably true, but if he was being honest with himself he had to admit that the main reason was that it just felt good to touch Blaine, even just his shoulder, even through at least three layers of clothes.

He stood there, hand still on Blaine, babbling about what the girls should eat for dinner, what they had to eat even if they didn't want to, what each of them wouldn't touch if their lives depended on it. After a few minutes of the most boring monologue ever, Quinn kissed him on the cheek and suggested that he get dressed while she show Blaine around and fill him in on the girls' rules and routines. He agreed and went to the bedroom.

After taking off his t-shirt, he caught a glimpse of himself in the mirror. Absurdly, he found himself wondering if Blaine would like how he looked shirtless. It was such an inappropriate thought, but once he asked himself the question he couldn't help but answer it. Probably, he thought. There were a couple gay guys at the gym he went to, and he had caught them checking him out. He had never cared much one way or another about those guys, but he had to admit he really liked the idea of Blaine liking how he looked. If he would.

Oh, God, he had to stop this line of thought. What the hell was wrong with him, he wondered, not for the first time that evening. He dressed quickly, not looking in the mirror anymore. When he rejoined Quinn in the kitchen she had to fix his collar for him. He blushed-he was pretty sure he felt himself blush-to have Blaine see him being touched by his wife.

Blaine was entering Quinn's number into his cell when Willa stood in front of him and started talking to him. But Willa was quiet, as she usually was around people she didn't know well, so Blaine had to get closer in order to hear her. And he could have crouched, Sam would have been fine with that. But no, he bent at the waist so that Sam got a perfect view of his ass sticking out.

And what an ass, Jesus. Round and soft and smooth. Sam realized that he couldn't actually see whether it was smooth or not, which made him realize that he was picturing it in his head. Oh God. "Quinn, honey, we should get going."

"Oh, you're right! Let me go get my coat..." And she left the kitchen.

Sam's coat was on the back of a chair in the kitchen. He put it on, not letting himself stare at the babysitter's ass. "Tillie! Hug and kiss good-bye?" he yelled.

Matilda ran into the kitchen a few seconds later and he scooped her up into a bear hug, kissing the left cheek, right cheek, then left again. When Quinn returned with her coat on, he picked up Willa and kissed all over her face. "Bye-bye, honey. Be good for Blaine."

"No, dada," she said. Tears were starting in her eyes. "Dada no go."

Quinn took her from Sam. "We'll be back when you wake up in the morning, sweetie."

Willa started crying for real and yelling "No go! No go!" Matilda reached up and tried to pat her head soothingly, telling her, "It's okay, Willie. See, I'm not sad." But Willa was howling and her little face was dark red when Quinn handed her to Blaine, telling him, "She'll be fine as soon as we're gone."

"She always gets like this when we leave," Sam said apologetically.

"It's fine," Blaine said. He tried to bounce her in his arms, but she was way too frantic. "We're gonna have fun, aren't we, Willa?" Willa was having none of it, so he tried with her sister. "Aren't we, Matilda?"

"Yeah," Matilda said. "We're gonna have fun, Willie. I'll let you play with my second-...well, my third-best dinosaur."

"Thanks, Tillie." Sam tousled her hair before giving Blaine another apologetic glance. "We'll be back around midnight," he said as they headed out.

But it was actually closer to one when they got home. They found Blaine sitting cross-legged on the couch with a book in his lap, but one cheek was red and had crease marks, so he'd obviously fallen asleep. Not that that was a problem. Matilda was perfectly capable of getting him if she'd woken up and needed anything, and Willa...well, there wasn't a person alive who could sleep through her nighttime crying.

"How was the party?" Blaine asked them as he stood up.

"Excruciating," Sam answered. He normally wouldn't have said so in front of Quinn, but he had been watching every word he said for so long he couldn't do it anymore now that he was finally home.

Luckily Quinn didn't seem offended, she just asked Blaine how the evening had gone.

"Oh, fine," he said. "Willa went to sleep right after dinner. I think all the crying wore her out. When I put Matilda to bed I asked if she wanted me to read her a bedtime story, but she wanted to read one to me instead. I learned a lot about the late Jurassic period."

Sam chuckled. "I don't know if she can really read or if she just has all her books memorized."

"Either way it's impressive," Blaine said.

"She gets it all from her mother," Sam said.

This time Quinn chuckled and kissed him on the cheek. "You're shameless," she said, "and I am going to bed. Thank you so much, Blaine." She shook his hand and walked off toward the bedroom.

"Well..." Sam said when she was gone. "Are you ready?" He took some money out of his wallet and handed it to Blaine as soon as he had his shoes back on. Blaine seemed almost reluctant to take it.

They didn't talk on the drive back to Blaine's house. Sam didn't know what to say, and he thought Blaine was probably tired anyway.

He pulled into the driveway and got out to walk Blaine to the front door. Blaine said, "Oh, you don't have to-"

"Don't be silly," Sam said. "It's dark and I have to make sure you get inside safely." He always walked Tina to her door when he took her home after babysitting. True, he didn't usually take her arm while he did so. But it was icy, he didn't want Blaine to slip and fall.

They reached the porch and a motion sensor light went on. Blaine put his hand on the doorknob but then stopped and turned to look at Sam. "I had a lot of fun. I mean, your kids are great."

Sam smiled. "They really are. But I guess I'm biased."

"Well if you ever need a babysitter again...And I mean if Tina's not available..."

"That sounds great," Sam said, already trying to think of the next time he'd need a sitter.

And then, he had no idea what possessed him, but the next thing he knew he was cupping the back of Blaine's head and softly kissing his lips. Several seconds passed between the moment he realized what he was doing and that he had to stop and the moment he actually pulled away. "Blaine! My God, I'm so sorry!"

"It's okay, Mr. Evans."

"No! It's not! It's the most inappropriate thing I've ever done. Please don't tell...Oh God, listen to me. Now I'm trying to swear the victim to secrecy. No, tell anyone you want-"

"Mr. Evans-"

"Really, Blaine. You should probably call the police. I'm so-"

Blaine's lips were on his again, and he knew he hadn't done it this time. This time he gave himself over to it, trying not to think about how wrong it was, how even though Blaine kissed him this time he was the adult and he was the one who was responsible. It was shockingly easy to block those thoughts out. Blaine's lips were so warm and so sweet, and the way he stood on his tiptoes to reach Sam's just about killed him.

And Blaine-even though he started the kiss this time, he was so shy and nervous. He opened his mouth and his tongue got closer and closer, until finally Sam had to slide his tongue into Blaine's mouth. But then Blaine tried to practically devour it. And Sam placed a hand on Blaine's waist and felt him trembling. Sam pulled away from the kiss, reluctantly, and put both hands on Blaine's shoulders, trying to steady him and get him to stop shaking. He inspected his face to see if he was all right, and sweet Jesus was the boy beautiful. Even more so than before, now that his cheeks were flushed and his pupils dilated.

Blaine looked down at his shoes, but he didn't attempt to move away from Sam's touch. "I'm sorry, Mr. Evans. I've never..."

"Was that your first kiss, Blaine?"

Blaine nodded, still not looking up.

"I'm sorry. I'm so sorry, sweetheart, that your first kiss was with an old married man."

Blaine did look at him now, he looked right into his eyes. "I'm not sorry. It was better than I hoped for."

"Blaine..."

"No, I know. I know it was just a kiss and it didn't mean anything. Don't worry, I won't tell anyone."

"Well. But if you wanted to I wouldn't blame you."

Blaine shook his head. "I don't want to. I...I promise not to do it again, if you ever let me sit for you again. I'd really like to."

Sam didn't know what to say at that moment. Hiring Blaine again-ever even seeing Blaine again-was obviously a horrible idea. But he couldn't bring himself to say that. In the end he patted him on the shoulder and said, "You're a good kid." He stepped down off the porch. He turned to watch Blaine unlock the door and get inside safely before he went back to his car, to drive home to his wife and kids.
