Chapter Text
Stiles wakes to Derek’s hands roaming over his body. “Mmm, that feels nice.” his voice still heavy with sleep.
He feels kisses up the length of his body, never lingering in one spot, until Derek reaches his mating bite. The were gently presses his teeth against the impression causing Stiles to moan in pleasure. “Happy birthday baby.”
“Mmhmm. Definitely. Do that again. Always feels so good when you do that.” Stiles feels the pressure when Derek grants his wish. “God, yes. Always so good to me.” He turns to capture his mates’ lips in a kiss that quickly becomes heated.
Derek breaks the kiss and Stiles tries to bring his lips back, but the man chuckles and whispers in his ear. “Turn over.”
Sensing the were’s intentions, he complies and receives a slap on the ass once he’s on his stomach. “Hey! Oh !” His exclamation is cut off when Derek parts his cheeks and he can feel a tongue on his hole. “ Fuck !” Stiles is in a state of ecstasy when Derek presses a finger in. He’s sure that Derek’s a mind reader because the man always knows just what he needs. It’s not long before Derek has him properly stretched and Stiles can feel him lining up. “Mmm, best birthday ever.”
He hears Derek’s attempt at a chuckle get drowned out into a moan as he bottoms out. “Yes- mmm- for your birthday, but I’m pretty sure I’m getting something outta this too.”
Stiles lifts his hips a little, which pushes Derek further in. “You’re definitely getting some, that’s for sure.”
Derek’s hips start snapping and he grunts out ‘ you’re a menace ’. The man braces his hands on the small of Stiles’ back and slows down his pace. Stiles loves it this way. Honestly, he loves all the ways that Derek’s cock fills him. From hard and fast, to grinding on him when he’s on top, but there’s something about the longer and deeper thrusts that truly tear him apart.
Maybe it’s the sweet friction it causes on his straining dick against the mattress. Honestly, he’s not sure because right now his mind is blank, and his mumblings are incomprehensible. The mind reader knows. Of course, he does. Because Derek lifts Stiles and begins stroking him in time with his thrusts. “Are you close baby? Do you need to cum? I wanna feel you cum. You feel so good when you cum.” aaannd he’s dead. That damn dirty talk has come to claim him, just like he always knew it would.
He’s lost in the euphoria of Derek fucking him, stroking him. All it takes is a hot breath on his ear telling him to let go and he’s lost, falling into bliss. And he knows Derek isn’t lying about loving the feeling of Stiles’ climax because soon he feels his mate pulse inside him as he has his own. Best birthday ever.
As they’re in the shower, preparing for the horde of guests that will soon swarm the loft, Stiles starts complaining. “Can’t we just cancel the party and lie in bed all day. I mean it could just be a day of marathon sex. It’d be the best present ever.”
He can feel Derek roll his eyes. “Stiles, we’ve had sex twice already this morning. And I’m sure we’ll have more later, but it’s your birthday and the pack want to celebrate.”
“We haven’t had sex twice. I think I’d remember if we had sex twice. I can name every single time we’ve had sex Derek. Our first time was-”
“Of course, you would focus on that . I seem to remember someone waking me up at what, 4am?”
Stiles gets a dreamy look as he remembers getting up for a glass of water and getting an instant boner at the sight of the bed sheet riding low on Derek’s hips, showing just the top of the man’s ass cheeks. “ Yeah …” he sighs, happily.
He feels the hard press of Derek behind him, the were not at all unaffected by the waves of lust rolling off his body. “God, what you do to me. That you let me take you however I want. I’ll give you the world.”
Stiles turns in his arms, wrapping him into a tight embrace. “I don’t need the world. Just you. Always you.”
Derek kisses him. Gently at first, but soon it builds, and Stiles now understands what Derek meant about the awkwardness of shower sex, but he can’t get over the fact that his boyfriend fiancé would always do everything in his power to give Stiles all he wants and that makes it beautiful. “Happy birthday baby.”
“I love you, Der.”
He spends the rest of the weekend surrounded by his family and pack, and Stiles dreams of their future. A home for their family, the rooms filled with the laughter of their children. After dealing with Scott being bitten, his mother’s death, and Lydia’s constant rejection of his advances, he can’t believe that this is his life. Apart from the Darach, in the few months since meeting Derek, his life has changed for the better. He’s gained new friends, more family, and a love he never thought he’d have.

It’s his first day back to classes after spring break. Walking into class, he’s shocked to learn that his favorite professor had transferred. The man at the board is not someone he recognizes, not having seen him around campus before. He’s not a man that would go unnoticed. He’s older, tall, with blonde hair, but it’s the dark glasses and cane that would draw attention. He’s blind.
There’s a lilt to the man’s voice that he can’t quite place. It’s soothing to listen to and Stiles must fight to stay awake while the man lectures. He jolts up when the bell rings, signifying the end of class.
He really shouldn’t have done such an early class for a Monday. Usually it’s not a problem going to bed early on Sunday nights, but between his birthday festivities and working on the Hale house, he had a pretty late night. Also, sex.
“Mr. Stilinski?”
He looks up as the professor makes his way over to where he’s sitting. “Yes, professor?”
He watches as the man easily walks up the steps through the crowds of students filing out of the lecture hall and finds him even though he’s in the middle of a row. “Please, call me Deuc, Miecyzslaw .”
Stiles narrows his eyes at not only the use of his birth name and that it’s pronounced correctly, but at the way the man said it, almost seductively. His name is not seductive. “Uh, of course, prof- er, I mean, Deuc. But only if you’ll call me Stiles. Only my dad calls me Miecyzslaw.”
Deuc holds his hand out and Stiles wants to ignore it, pretending to be busy packing up his notes, but when he does, he feels a pressure at his back where the man leans over him, hand on his shoulder. “Professor Davidson left some notes on his classes and you were promised to be a wonderful student. Imagine my surprise when you started nodding off during the lecture.”
He shifts away as the man breathes into his ear. “Uh, yeah about that. It was a long weekend. My fiancé and I are remodeling his family home, so we can move in after our wedding.”
“Fiancé?” Deuc stands back up but leaves his hand on his shoulder. “Well then, congratulations are in order.” He feels pressure on his shoulder where the man squeezes. “To a long and happy marriage.”
“Uh yeah, thanks. I should really get going though, next class is soon, and I clearly need some caffeine, so…”
“Yes, well, it was a pleasure to meet you, Stiles. See you at next class.”
He gathers up his remaining items and says, “sure thing professor,” before rushing from the room.
By the time all his classes are done, and he just wants to go home and crawl into bed, hopefully with Derek for some cuddles. The elevator to the loft is broken and he groans at the realization that he’ll have to trudge up the stairs to the top floor. Fuck my life!
He slides open the loft door and immediately heads for the were, wanting to be wrapped in warm hug. The professor had been niggling at the back of his mind all day. Bad touch, bad touch is all he can think. Up the stairs to the study he goes, knowing that’s where the man is. The door is open, and he can see Derek looking at the bookcase on the wall. Never really able to surprise the man, he walks up to place his hands on his mates’ waist.
Suddenly Derek spins and snarls, eyes red, face half shifted. Stiles stumbles towards him, looking back towards whatever danger the man sensed. “Der, what’s going?” He feels claws at his waist, turning him back to face his mate.
Derek’s eyes still glow red, but his face is no longer shifted, just a mask of confusion. “Stiles?” The were leans his head forward and sniffs at Stiles’ neck and shoulder. A growl erupts from his mate’s chest and he’s pushed back slightly. “Who were you with?” Derek asks, the words harsh on his ears.
He frowns at the question, at the look of contempt on his lovers’ face. “Wha? I wasn’t with anyone. I’ve been at school all day. You know that.”
“Don’t lie to me Stiles. I can smell him all over you.” The disgust clear in his voice.
“I’m not lying, Derek. I wouldn’t-“ He tries to step closer, wanting the comfort of his mate. Derek reaches out for him, but suddenly Stiles can see his nostrils flare, a terrified look on his face. Stiles doesn’t understand what’s wrong.
Derek keeps his distance as he goes around Stiles. “I know you’re not lying but- you don’t smell right. All I smell is the were. I- I can’t. I need to go.”
Tears spill as his mate leaves the loft.
