The first time Kurt met Blaine was at his dads wedding. It had been a sudden thing, hearing that his dad had proposed to Annemarie and that they were going to have the wedding in less than a month. Kurt had thrown it together with help from the Glee Club, Cooper (Annemaries older son), and Annemarie herself.

Everything had been perfect, even Cooper face-diving into the punch fountain. His dad was happy, Annemarie was his stepmom, and both of her boys seemed happy for the pair, too.

"H- hi, Im B- Blaine."

Kurt looked away from his friends at his table and found a younger boy looking at him. Annemaries younger son, Blaine. Kurt didnt know much about him. He lived on the east coast with his father, was fourteen, and alarmingly geeky looking. But appearances werent everything. Four years of high school had taught Kurt that. It wasnt Blaines fault that he had wires all over his teeth, polka dot-zit cheeks, and a bush growing out of his head. His own body at fourteen had been anything but ideal. But Kurt was eighteen now, New York bound, and quite handsome from what he understood.

"Its nice to finally meet you," Kurt greeted. They shook hands and Blaines was so sweaty Kurt had to resist wiping his hand on his pant leg. "I bet its nice being back in Ohio for a bit."

Blaine nodded violently and tucked his hands into the armpits of his suit. "Y- yeah, its great. I miss seeing Mommy– uh, Mom." His voice squeaked on almost every word and Kurt heard Rachel and Mercedes start giggling. He couldnt blame them. Blaine was redder than a setting sun and beaming like Kurt once had at the sight of Finn Hudson. "D-do you want to, um, it was– d- do you want to d- dance with me?"

Rachel and Mercedes squealed with laughter behind him, but Kurt stood up and took one of Blaines sweaty hands. He never thought hed end up regretting one dance with his new stepbrother, but a year and a half later he started to.

Blaine and Cooper had gone back to their homes after the wedding. Kurt got into NYADA, graduated and moved off to New York City with Rachel, and by the time Kurt saw Blaine again hed forgotten all about his stepbrothers cute little crush. It hadnt seemed like a big deal at the time. Blaine had been fourteen and awkward, but a year and a half later, he suddenly wasnt.

Kurt noticed him the moment he stepped into the airport in Columbus. His dad and Annemarie were there, waving and cheerful. But a teenage boy was with them now and it took Kurt a moment to place him. Blaine wasnt a little shrimpy fourteen-year-old anymore. A young man was standing at his dads side; the zits were gone, the braces had been taken off, his hair had been chopped and styled, and he was almost as tall as Kurt now.

"Kurt, its so good to see you, sweetie. Oh, you get more handsome everyday." His stepmother tugged him in for a hug and looked him over. His dad was next with a giant bear hug and questions about the finals hed just finished.

"Looking sharp, bud." Burt patted him on the back and took one of Kurts bags. "You remember Blaine, right? Annemaries youngest? You two only met once at the wedding. Hes staying for the summer, maybe for good if his dads okay with it."

Blaine smiled at him, but it wasnt like the smile Kurt remembered. There was no more wires and metal, sure, but it was softer, more relaxed and sure.

"Its good to see you again, Kurt." Blaine held out his hand to shake and something in Kurts knees shook. The younger boys appearance wasnt the only thing that was suddenly different. His voice was deep and smooth as cream now.

"Y- you, too." Kurt took his hand and his entire face heated up at how dry and strong Blaines grip was now.

They drove back to Lima, had dinner at Breadstix, and returned to the house. Blaine had been moved into Kurts old bedroom basement, and Kurt didnt like the way his stomach twisted when his dad said theyd be sharing the room for the two weeks he was here. Blaine didnt react, maybe his crush had passed, but Kurt could already feel his beginning. How could he have a crush on his fifteen-year-old stepbrother? He was almost nineteen. This was completely ridiculous after all of the older, handsome men hed dated and had sex with in the past year.

All that first week, Kurt got to know Blaine. He had a tour through all of Blaines CDs, his iTunes library, his books and movies, and his bow tie drawer. The more Blaine and he talked the more he liked him and the more Kurt blushed and fumbled with his silverware at dinner and spilt milk down his front.

His short trip back ended on his birthday. It was the entire reason hed come back at the end of May for a visit. There was a small party, his favorite meal for dinner, and then a large chocolate chip cheesecake. His dad had given him rent money, Annemarie had given him supplies for his classes, and Blaine surprised him completely.

"Oh my gosh, its gorgeous," Kurt let the scarves flow out onto the table in all their bright glory. A deep purple, a soft cashmere in dark green, a striped monochromatic one. There were six all together. "These must have cost a fortune!"

"Ebay," Blaine explained. "Mom and Burt said you loved scarves and I found all the ones you left here in the closet downstairs, so I picked a few I thought youd like."

"I love them," Kurt beamed. He flung his arms around Blaines neck and squeezed him tight. It felt better than any hug hed ever had before, better than sinking into a hot bath or a deep, restful sleep. When he pulled back, Blaines eyes were dark and his fingers lingered longer than they should have on Kurts side.

They trooped downstairs after cake for showers and then bed. Kurt insisted on Blaine taking his first to avoid being too obvious when he took an hour. But Blaine was in there for a long time, too, and the more Kurt thought about it, the harder he grew. After twenty minutes, Kurt couldnt stand it anymore. He took one glance at the closed bathroom door, listened to the running water, and unfastened his jeans. With one tug, he pulled his hard cock free and gave it one languid stroke.

"Fuck," he breathed. It had been too long since hed gotten laid, that was all this crush meant. He didnt really like his stepbrother like that.

"Kurt, the showers yours– oh! Um."

Kurts hand froze on the upstroke, his eyes shooting open. Blaine was standing beside his bed, towel around his neck and pajama bottoms low on his hips. One look over the lightly muscled, still thin chest, and Kurt had to bite his lip and shut his eyes again. He was awful. A complete monster. What just nineteen-year-old had a thing for his fifteen-year-old stepbrother? This was insane, this was–

"Oh my– B- Blaine, what?"

Blaine had sunk down to his knees in front of him, a hand on either of Kurts thighs. "You, um, look like you could use a hand," Blaine said quietly. "Ive had plenty of practice on myself, so…"

Kurt groaned and pulled his pillow over his face. But his lack of response didnt deter Blaine. Instead one trembling, hesitant hand closed around the base of his cock and squeezed. It was a gentle touch and Kurts hips jerked up, his cock sliding through Blaines fist until he groaned.

"Is that a yes then?" There was a smile in Blaines voice as Kurts hips dropped back down. Blaines fist stroked over him again, more firmly as Blaine wedged between his legs. Kurt moaned louder. "Ill take that moan as a yes."

Kurt held the pillow over his face as Blaines hand moved, slow and tight, changing tempo and twists until Kurt was panting and arching into the movement. His hips sunk back into the mattress. He was trembling and gasping in a way he hadnt in a long time. None of the men in New York City could get him to this pleasure so easily. Maybe it was the innocence in Blaines fingers petting his bare thigh or the soft brush of Blaines lips and tongues on the underside of his aching cock.

"S- shit," Kurt mumbled as Blaines tongue curled over the head of his cock. "Im gonna– oh god!"

He came harder than he had in months, all over Blaines cheeks and eyelashes and his own stomach. He was breathing hard and gasping when his stomach finally stopped pulsing and Blaine sat back. The other boy swiped a spot off his cheek and gave it an uncertain lick. "Hmm, thats not so bad."

"Oh my god," Kurt breathed. He grabbed his pillow and pulled it back over his face. "Did you– I cant believe– this is illegal!"

"Only a little bit," Blaine said. He plucked a few tissues from the box on the night-stand and wiped his face off. "Look, it was just one orgasm. I offered, and I took care of myself in the shower, okay?"

"I – goodnight." Kurt rolled over and pretended to fall asleep. By the time he returned to New York City the following afternoon, he was horrified with himself for not putting a stop to what had happened and even more worried with how much hed wished he could have returned the favor.

Kurt didnt go home for Christmas that year. He stayed in New York City for every break and holiday for a year until his dad threatened to come up there and follow him around for a month. By July, he gave in and came back for his dads birthday. There was no avoiding Blaine forever, hed decided. His stepbrother and he would just have to sit down and talk this out, draw lines and boundaries and belts with locks.

But Blaine was nowhere to be seen when Kurt showed up at the house. Hed driven down to surprise his dad and Blaine wasnt there. For one hopeful moment, Kurt had dared to imagine Blaine had moved back to his dads place, but Annemarie said something about a movie date when he asked. Kurt heaved a huge sigh of relief. Blaine had a boyfriend now. There was nothing to worry about, even if they shared a room for a few more weeks. At least that was what he thought until he was woken up the next morning to a piano alarm clock.

"Sorry."

Kurt squinted through the semi-darkness and watched Blaine slapped the alarm clock off. Then his eyes took in the length of Blaines arm, thick and strong. His muscles had filled out beautifully from wrist to shoulder and all over his bare chest, down his stomach to... Kurt blushed and looked away. His stepbrother was naked, his blanket tangled around his ankles and his cock bobbing slightly against his navel.

"God, its hot down here," Blaine said as he laid back down. He folded his arms under his head and stretched his legs out over the bed. Kurt gulped and shut his eyes. Blaine had filled out everywhere Kurt shouldnt want to think about. When he opened his eyes, Blaine was giving him a lazy smile as one hand rubbed over his belly. The new confidence was attractive and an awful turn-on. "You dont mind if I take care of this, do you?"

Blaines hand closed loosely around his own cock and Kurt shivered at the sight. Hed never seen Blaine naked before, but he could easily imagine how different he was from a year ago. A broader chest, thicker muscles and thighs, and a thick, slightly curved cock that was just aching to be–

Kurt shook himself and sat up. But nothing could block out Blaines soft moan and the creak of his mattress. "Mmm, its better when someone else does it," Blaine said quietly," but…"

He trailed away and groaned until Kurt had to look. Blaines cock was in his fist, his other arm propping him up as his hips worked up and down, up and down… Kurt was mesmerized by the sight. From Blaines hips to the sweat starting to slick up his torso.

"Mmm, so good," Blaine moaned. "God, Id love to be stretched open right now. Kurt?"

Kurt nearly toppled off his bed at the sound of his name. Deep, lyrical, Blaines voice had somehow gotten more sexy since last summer. He couldnt do this again. Blaine was sixteen. He was twenty. This was so, so wrong. Even watching made him a pedophile, didnt it?

"Kurt? Can you– oh, god– can you get the lube out of the drawer for me? Id do it myself, but–"

Kurt fumbled with the handle and looked in the drawer instead of at Blaine arching into his own grip and panting. But inside the drawer was more than a bottle of lube. There were condoms, a cock ring, three vibrators of various size and shape, and what Kurt thought looked like a prostate stimulator. He dug the half empty lube bottle out and gave it to Blaine, hoping the other man wouldnt notice how he was trembling and how badly he was tenting his pajama pants. Blaine popped the cap and rolled away from Kurt. Kurt didnt remember much after that. His eyes were transfixed by the round, perky swell of Blaines ass and the slick fingers that were thrusting into it.

Every morning or evening for the next twelve days Blaine jerked off when Kurt was in the room. He stroked himself, stretched himself, and moaned and whined and cried out when he slid one of his vibrators inside himself. On Kurts last day, he was aching hard from the time he woke up until he crawled into bed. Blaine was out with a few friends for the evening, and Kurt was relieved. Hed been woken up by Blaine that morning, kneeling on his bed and working himself up and down on his thick purple vibrator. Kurt hadnt had a rational thought since.

He fell asleep thinking about hitting a club as soon as he got back, but how he woke up changed his mind. An avid mouth was sucking over his cock, his pajama pants had been removed, and his skin was burning.

"Wh– Blaine?"

Blaines eager mouth sealed itself against his, tongue darting in and the bitter taste of alcohol hit Kurts taste buds. They kissed feverishly until Kurts head caught up with his body and he realized his hands were tugging on Blaines bare ass cheeks.

"Blaine, this is–"

"Illegal?" Blaine supplied. He started sucking down Kurts neck. "So were the three drinks I had tonight, but that didnt stop me. Come on, fuck me. Ive wanted to ride your beautiful cock since you got here."

Blaines knees dipped into the mattress on either side of Kurts hips and a condom was pressed against Kurts chest. Speechless, Kurt let Blaine kiss over his neck and shoulders, then start sucking on his right nipple. Kurt groaned and arched up, his cock sliding along the crease of Blaines ass.

"Did you–"

"Im all ready for you," Blaine breathed. He pinched Kurts other nipple until Kurt whimpered and jerked under him. "Please, I need you."

Blaine was hot and tight when Kurt pressed in. The empty condom wrapper fell down between them as Blaine arched and sunk down, his mouth open and his breath coming in short gasps. "Oh, god, youre so thick. Thats so good." Blaine leaned over him, his eyes dark, his cheeks flushed, and his cock heavy and bobbing between them.

Had Blaine done this before? Kurt couldnt help but wonder as they started kissing roughly again. He took Blaine by the hips and as Blaine struggled to start gyrating and find a rhythm, Kurt started to guide his roll and angle. It was clumsy and awkward, but Kurt had never had a better moment. Blaine panted and whined, his movements slowly gaining steadiness. Kurt let him ride then, one hand stroking over Blaines cock and the other caressing Blaines cheek. Blaine turned his face into Kurts palm and cried out, his hips rolling and arching higher. This was wrong, but this gorgeous boy wanted Kurt as much as he wanted Blaine; wanted to share his first experience with Kurt.

Kurt stroked him faster, until Blaine fell forward again and cried out. He stopped moving then, his chest heaving as his come spilled over Kurts belly and fist. Inside Blaine he was still throbbing for release. For the first time he was disappointed in having developed good sexual stamina. Maybe next summer hed get to help Blaine with his.

But next summer didnt happen. Kurt found a wonderful full-time job for the summer and stayed in the city. It wasnt until mid-December when Kurt saw Blaine again. He didnt know what to think anymore. There were so many reasons not to continue this. Blaine was his stepbrother. He was underage. Hed had alcohol in his system last time. The list went on forever, but Kurt couldnt bring himself to care. Being with Blaine, whether it was hating him for masturbating every morning or talking about Idina Menzels voice and Alexander McQueen, was a thrill Kurt couldnt explain with logic. Everything about him was a wonderful piece of Kurts memory.

They ended up in the kitchen together right before dinner, grabbing the last two dishes for the table.

"Hi," Blaines arms circled around his waist from behind and his chin hooked over Kurts shoulder. "I missed you, handsome."

"Blaine," Kurt began, but Blaine cut him off.

"You missed my birthday this year, you know. Not even a card," Blaine said quietly. "Eighteens an important one, too."

Kurt stiffened at his words. Eighteen. Blaine was eighteen now. He wasnt a freaky creep anymore. Well, he still might be. They both might be since they were technically stepbrothers, but did that count really? They hadnt grown up together or even known each other until their parents had gotten married four years ago.

"I– sorry," Kurt whispered. "I just–" He couldnt think of anything adequate to say so he turned in Blaines arms and kissed him soundly on the mouth. "How about I give you my Christmas gift early instead? After dinner."

Blaine smiled up at him, his eyes twinkling. "I was hoping we could exchange presents a little early." He kissed Kurts jaw and arched his hips forward until Kurt could feel his arousal against his thigh. "Ive been waiting to give you yours all day."

Kurt shivered and dipped one hand into Blaines back pocket to squeeze. "Are you ready for me?"

"I will be. Ive been practicing, too," Blaine teased. "I bet I can ride a dick better than you now."

"What makes you think I bottom?" Kurt returned as one of Blaines hands slid under his sweater.

"With a sexy ass like yours? Please."

Kurt laughed and let Blaine drag him down for deep kiss.

"Annemarie! You own me sixty dollars! I told you theyd get together!"

They broke apart just in time to watch as Burt hurried back into the dining room.
