These drabbles can be read chronologically or not. Dealer's choice. I'm writing them in a progression style but they all pretty much stand alone.

A/N: I wanted to wait to post this, but screw it.

The months pass, fly by really, and soon it's March before Derek knows it.

It's getting a little hectic now with not only school and part-time work at the clinic for Denton but lacrosse that he doesn't see Isaac as much as he would like. And when he does Isaac looks dead tired; shuffling in from practice, games, work, or school like a zombie. He tells him that he shouldn't push himself so hard, tells him he should think about conserving his energy for possible threats and training instead of wasting it on frivolous things like sports and volunteering. That doesn't go over well. Isaac snaps at him that they weren't 'frivolous' they were things he enjoyed and he could take care of himself, Derek didn't have to worry about him. But he did. Derek did worry about him. It took a full day of moody silent treatment from the younger man to get Derek to apologize, and when he does Isaac agrees that maybe he was doing too much. Denton lets him cut back to an 'as need' basis and he agrees to spend alternating Saturdays either completely resting or training to Derek's satisfaction. The Alpha agrees, but gives a strict warning of 'if you're too tired to hold your own in a fight and die, I won't feel sorry for you.' They both know it's all bluster. But Isaac doesn't know that if he died Derek would be devastated.

Today was one of those 'off' Saturdays and they decide to celebrate the day off by sleeping in. Derek doesn't sleep in often, preferring to train or run or do something, but he's becoming accustomed to it thanks to Isaac. The boy likes to sleep in. And Derek can admit it's not so bad, when he has the time.

His listless sleep is disturbed when the blank empty space behind his eyes suddenly becomes a vivid display of heat and friction and tight wetness. His mind plays images of Isaac wrapped around him and his sheets, his moan when he rocks against him, that perfect happy coy smile on his lips before they wrap around him. Derek moans. It feels so real.

He moves his hips, trying to get more of that imaginary friction, but is stopped when he hears a gag and large hands rest on his hips to keep him still. Green eyes fly open then and he realizes that the heat and the friction and the wetness aren't imaginary at all.

"Fuck…" Derek chokes, seeing a mess of curls nestled against his pelvis before his head falls back against the pillow. God damn Isaac was good at this.

His hand comes down to lace in the mop of hair and they moan in unison; Isaac moaning from the feel of Derek's hand in his hair and the slight tug, Derek from the vibrations the moaning put into his cock. God he's so hard now. He can smell that Isaac is too, turned on from sucking him off and that turns Derek on. He wants so bad to pull Isaac up by his hair, kiss him hard, flip them over, and make Isaac his over and over again. But he won't.

Despite dating for about 6 months, they still hadn't had actual sex yet, much to both their misfortune. Even though Isaac was 18 and willing (more than willing) Derek still felt uncomfortable about sleeping with a high school student. It left a bad taste in his mouth. Isaac, though miffed and pulled the 'lots of other high school students have sex' with no success, accepted Derek's decision. He didn't leave Isaac wanting for much more though. He was still a guy, a werewolf guy at that, and despite people thinking he was frigid he did have a pretty high strung libido. He just preferred to be high strung with one person, not hump everything in sight.

Apparently Isaac was similar. He had been surprised to find out how insatiable the Beta could be; having thought he'd need to convince him that everything would be ok or take the next step, but it had been Derek who had to tell Isaac to stop on more than one occasion. It was the face, Derek thought. Isaac's handsome, almost cherub face hid the beast within.

A loud gasp catching the tail end of a curse comes out of the Alpha's mouth when Isaac takes him all the way in and down his throat. He's not going to last long, the surprise blow job catching him and his usual stamina off guard, and soon he's all but biting through his bottom lip when he cums; his cock twitching when he feels Isaac swallow around him.

Derek flops against the bed panting when his back unbows and tiredly reopens his eyes to look curiously up at Isaac when he crawls on top of him.

"Happy Birthday."

Oh yeah….it was the 15th wasn't it.

*- I don't know when Derek's birthday actually is but international betrayal day (March 15th) seemed fitting
