Summary: The Warblers are just everyday teenage boys. Except for, you know, being werewolves. But when their Alpha male, Blaine Anderson chooses an outsider, Kurt Hummel to be his mate, things will start to get a little...wild.

A/N: Okay, so this chapter was fun to write. I hope you guys enjoy it!

I'm just going to say it. This week is the best week of my life. It may even top Valentine's Day, when Kurt became my mate officially. At one point I had thought that nothing could ever beat that. But then this week happened, and Kurt went into heat.

I didn't realize it at first that Kurt was in heat. Neither did he, since it was his first heat. Normally carriers go into heat during December, but Kurt wasn't changed until before Christmas, so it makes sense that he would go into heat in February, when his body had time to adjust to being a werewolf. Normally, when Thad or Trent go into heat we lock them up in their rooms because otherwise they are all over me. Jeff is a little easier to deal with, since he has a boyfriend who is more than willing to fuck him until his heat is over.

I supposed in the back of my mind I realized that Kurt would be going into heat soon, but I really didn't recognize the signs. It started one day at Warblers practice, after Rachel had invited us to what Kurt had dubbed as her 'Trainwreck Extravaganza.'

"So we'll be going after Briggs and Gandell Corp.?"

I was currently talking to David and Wes about the latest murder we had to plan. Wes' father had sent in a file, asking us to take out some of his competition. It was an easy enough task, though we would have to go up the Hamptons to complete it.

Suddenly Kurt bounded into the room and sat down beside me. I immediately gave him a smile, but I really didn't have time to talk, so I turned my attentions back to Wes and David. However, that just wouldn't do for Kurt.

I began talking to the two Warblers in front of me and suddenly Kurt was snuggling up against me. He rubbed his head into my shoulder, rubbing up against me. Not that I really had any protests, but I was trying to have a professional meeting here! I can't really have my boyfriend dry humping me in public. I have a little more class than that.

I had thought that Kurt did too, but apparently not. I pushed his head away gently, but it was to no avail. I saw Wes and David smirking out of the corner of my eyes. What was that all about?

The next time it happened was when we were in class. Class of all places! Really, I had assumed Kurt, who had been a prude until I finally tapped that, would have more decorum, but I didn't know he was in heat. So sue me.

Anyways, I was busy at my lab table trying to take notes on some chemical formula or whatever, when Kurt started playing footsie with me under the table. At first it was nice, but then his foot began creeping further and further up my leg.

And then he started palming me through my khaki slacks.

"Kurt, we're in class!" I hissed to him under my breath, a blush creeping to my cheeks. Was this some weird sort of karma? I always thought about fucking Kurt, and now suddenly he was doing it in public? Okay, so exhibition really isn't my thing, unless it's because of jealousy or something.

"I know." Kurt said with a smirk, and continued rubbing me through my slacks. I swatted his hand away, and he pulled back. But only for a moment. After a few seconds his hand was back on my crotch, and he was at it again.

This time he had decided to go a little further though.

"I'm so hard for you right now."

I tried not to gape at the low whisper Kurt spoke into my ear. Good god, he was making me hard, and we were in class! I saw Thad glaring at us out of red rimmed eyes, and I actually felt embarrassed, rather than smug. Really, getting off with one's boyfriend in a public setting with your lifelong stalker watching you is not as cracked up as it seems.

"Okay Kurt, that's great. Now let's go back to AP Chem, okay?" I was desperately hoping to discourage my boyfriend, but it is really hard, considering I'm torn because I really, really want to have sex with Kurt right now, but I know that class is totally inappropriate for it.

"Why not? We're both horny as hell, and I really want you to fuck me."

Hearing the vulgar word slip out of Kurt's mouth made me bite back a moan. What the hell is he playing at? Is he trying to get revenge on me? Did I do something? What the hell is going on here? He knows that I'm busy tonight with a few projects, that I'm too busy for sex, what the hell is wrong?

It wasn't until after class that I figured out what it was.

"Hey Blaine!"

I turned around and saw David running towards me. "Oh hey David." I said pleasantly. I was on my way to the library so I could finish up my project for World Economics. It was worth fifteen percent of my grade, and I really needed to do well on it. My father still lived under the impression that I would follow his line of business, even though I knew that was doubtful. I love music, and so does Kurt. He definitely wants to go into theater, and I would gladly follow him.

"I'm surprised to see you out and about. Actually, I was surprised to see you in class today. Kurt too. What's up with that?"

I looked at David in confusion.

"What do you mean? Why would you be surprised?"

David looked stunned.

"Well, I mean, Kurt's in heat, isn't he? Normally Jeff and Danny spend the whole week fucking, and based on how you two already go at each other, I thought you'd be too busy screwing each other's brains out to even eat or sleep, let alone attend class."

I gaped at him, completely caught off guard. Kurt…Kurt was in heat? Oh god, Kurt was in heat. It suddenly hit me, remembering that Jeff, Thad and Trent were usually pained seriously hurting until someone fucked them. And I hadn't jumped on the opportunity.

"Oh no, tell me you knew Kurt was in heat." David groaned, and I glared at him.

"Sorry, I can't catch up right now David. Let our teachers know that Kurt and I caught the flu." I quickly began running back in the direction of the room I shared with Kurt, and I threw the door open. I immediately noticed that it stank of sex. Good lord, how many times had he jerked off in the last few hours?

"Blaine, OH GOD, BLAINE!"

My head immediately whipped around, and I saw Kurt, lying naked on my bed, stroking himself. Guh. Was that drool? Maybe. I don't know. My brain kind of turned to mush at the moment, don't mind me.

Suddenly looking up, Kurt's blue eyes met mine, large and wanton. Seeing the desperate need in his eyes, I quickly snapped back to my senses.

In one fluid motion I had removed my shirt and tie from over my head, and I practically pounced on Kurt, the slapping of our bare skin sounding obscene. I rolled over with Kurt on top of me, his left leg wrapping around my waist. Our mouths were working hungrily, desperate for kisses and affection. This was hot, needy sex, more passionate than anything we had done before.

"'M not gonna last." Kurt gasped into my mouth, and I nodded. I quickly unbuttoned my jeans and boxers with Kurt's help. I reached across Kurt to grab the lube and a condom, but Kurt grabbed my wrist.

"No condom." I frowned. Ever since our first time Kurt had insisted we use a condom, but now he was shaking his head fiercely. "Something feels wrong about it. No condom." In the back of my mind I knew there was a reason we should use one, but in the almost drunken haze, I really couldn't think of it.

Almost as soon as my boxers were fully off, Kurt immediately dove down and took my length in his mouth, moaning like a whore as he did so. I gasped, unbelieving that he had actually done that. He was sucking my cock like an expert, even though we had only done this a few times. Oh god, that felt so fucking good, but I knew if he kept this up, it wouldn't last. As he dragged his tongue across the head of my cock, I tugged on his cinnamon colored locks, bringing him back up to me.

"Can't do that if you want me to fuck you." I gasped out, and immediately began kissing him fiercely again. While he was preoccupied, I slid my hand down his ass, and found, to my surprise, that he was already wet with lube. I looked at him in surprised, and he smirked.

"I've been waiting for you. Needed you to fuck me so bad, so bad, so I fingered myself. I thought of you the hole time. I'm already prepped, I just need you inside of me Blaine, please, please."

I was eager to comply, but something stopped me. Remembering the debacle this morning in class made me think of something I wanted. I wanted to try this badly, and I got the feeling that Kurt would like it as well. So I pulled away from him, ignoring the keening whine he let out, sounding for all the world like a rejected puppy.

"Tell me. Tell me how badly you want me, how badly you need me."

Kurt stared at me in shock for a moment, before finally catching on to what I was implying.

"I need you in me so badly Blaine. I need your huge cock in my ass, I want to be filled up with your cum. Please Blaine, I've been thinking about this all day, I need your cock in me now. I need you to fuck me more than I've ever needed this before."

I know it was mean. I know it was evil. But I decided to tease my boyfriend a little more.

"You were thinking about this all day, hmm? Pray tell, what did you think about? Did you fantasize about me Kurt? Were you thinking about fucking me senseless today? I can't help you until you tell me what you wanted today."

Kurt moaned, half in pleasure and half in want. "I wanted you all day today. I thought about sucking you off during your meeting with Wes and David, and you sucking me off in Economics. I thought about giving you a hand job during AP Chemistry, and at lunch-"

Kurt stopped, and I detected a bit of that familiar blush. "What about lunch? What did you want Kurt?"

"I-I wanted you to take me, right then and there on the table. I wanted you to rip my clothes off and claim me as yours in front of everyone, especially Thad and Trent."

It was too much. I flipped him over, and without warning, plunged my rock hard cock into Kurt's already opened hole. "Oh god, fuck Kurt. So wet and open for me, only me." I babbled, before taking a deep breath, and staring at him straight in the eye. "Keep talking."

"I see the way they look at you, and I hate it, because I want to be the only one who thinks of you like that, who gets to be fucked by you. They can't have you, because you're mine." Kurt's voice had taken on a petulant edge, adorably possessive, like a toddler with a toy. It was absolutely endearing, and I grinned widely.

Kurt frowned, obviously expecting a different reaction. He grabbed my wrist, and examined it for a moment. I was about to ask what he was doing, before he suddenly bit down, and sucked hard, biting while sucking-holy hell is that even possible?

When he was done, I saw that he left the mother of all bruises, and my steady rhythm faltered. He glared up at me possessively. "Mine." He reiterated. By this time I had completely stopped my thrusting, and Kurt frowned in dissatisfaction. I waited for a minute as he began squirming, before thrusting again, deeper and harder than before, without warning.

I managed to hit his prostate each time, resulting in a high pitched screaming. I swear, Rachel Berry has nothing on him, he must have hit notes so high only dogs could hear. Finally, I let go, filling Kurt up with the result of our activities. Apparently that was enough for Kurt, and he was coming as well.

We were soon a sticky, sweaty mess, and I knew it was gross, but I didn't want to pull out of Kurt. It was like there was something keeping me inside of Kurt, and so I stayed. We stayed in the same gross, icky, but incredibly hot position all night, and into the morning.

And then we just went at it again.

I love being a teenage Alpha werewolf.
