Chapter Text
Derek stood by the mirror and did up the last of the buttons on his new shirt; it was heather grey and fitted his toned body like a glove. As he did up the final button at the collar, a pair of manicured hands came around his front, stroking up and down his chest.
“Oh, honey. You look almost good enough to eat in that shirt. I bet the students will be salivating at the sight of you today. Their wet dreams coming true right in front of their eyes…” Kate purred, undoing the top two buttons of the shirt and showing off some of Derek’s tanned chest.
“You don’t want to look like a hard-ass on your first day sweetie. You need to be approachable for my students. I can’t have them all coming to me and fearing you.” She added, pressing a trail of kisses up his neck and to his jaw before moving in front of him and biting his lip. Derek’s hands snaked around Kate’s waist in her red satin blouse that matched her lipstick to a tee.
“I’m sure they’ll all be thanking some God for getting you as their History professor over your new TA.” He teased, cupping her ass lightly.
“Well, I got your attention, didn’t I?” She countered, her hands finding their way under Derek’s untucked shirt, her fingers trailing his defined abs.
“You certainly did that.”
“And now look at where we are? Living together in New York in a lovely apartment near campus. You’re my TA this year, meaning we’ll be spending even more time together…” She purred once again, one hand coming down to cup his pants, giving a light squeeze.
A moan escaped Derek’s mouth as he bit down on his own lipstick-stained lip.
“Just what you always wanted, eh?” She asked, a smile on her face that didn’t exactly reach her eyes.
“Yeah.” He said simply, looking down at her as if she’d hung the moon.

Kate and Derek had met on Derek’s first day as a Sophomore at NYU in his Advanced Latin class. She was Professor Fink’s TA and a senior herself at the time, and dressed to impress in a tight pencil skirt and Louboutin heels, her hair worn down in golden curls with impeccable makeup. It was love at first sight for Derek.
Over the semester, Derek would make any excuse to have a meeting with her, saying he needed help with his latin –which was a lie, as he was already almost fluent thanks to an interest in the language from a young age. Each time he’d see her, she’d look at him with a predatory grin on her face, as if she wanted to devour him, but there was also a look of excitement on her face, as if he was a challenge, something she could show off as a trophy. Her eyes often surveyed his athletic body and she’d often stroke his thigh during one-on-ones, or her hand would swoop along his broad shoulders as she passed him. Even though Derek knew it was against university policy to date his TA, but he couldn’t resist Kate; she was beautiful, powerful and intelligent. Derek thought he was lucky that she was paying him any attention at all when she could have anyone.
Kate was also a few years older than Derek; she was a ‘mature’ student even though she was only 26, meaning that there was a six year age difference between the two of them. That didn’t seem to get in the way of their relationship though; Kate seemed to enjoy being a cougar and keeping a toyboy. She enjoyed the power, because she definitely wore the pants in their relationship.
Derek and Kate managed to keep their close relationship a secret all year, not that they ever established a relationship. Kate was clever and kept Derek waiting all year, just in case anyone found out about their attraction to one another. Of course, the tentative touches and innuendos were there along with the teasing and dirty talk, but they never got down and dirty with one another until Kate wasn’t Derek’s TA anymore.
They’d celebrated by having a sex marathon all weekend, not leaving her Lower Manhattan apartment.
Kate had of course made sure Derek was worthy of dating her throughout the year, meaning that he’d not dated anyone either semester. This meant that when they’d finally had sex he’d been begging for it and used it to her advantage, building up her control over him and planting the first seeds of manipulation. To her, Derek was certainly attractive and book smart, but he was terribly naïve and relatively new to the big city. She managed to persuade him to stay for most of the summer with her after she graduated and started to slowly manage his life.
First, she made sure he dressed the part to be her hot-ass boyfriend. Gone were most of his sweatpants and ill-fitting hoodies, and instead Ralph Lauren polo shirts and fitted suits were his new everyday attire. Kate, being the daughter of Senator Gerard Argent in New York meant that she’d been brought up in the high life. She was used to a certain way of living, carrying a certain image, and she wasn’t going to have Derek let that image down.
Next on her list was to get him to cut ties with the less desirable friends in his life. Derek had of course been part of a Fraternity since freshman year, but in Kate’s eyes he wasn’t a part of the right sort of Fraternity. After managing to pull some strings before finishing college herself, Kate managed to get Derek into Kappa Sigma, when Derek had initially been part of the Pi Kappa Alpha. Soon enough, Derek was socialising with his new frat brothers more and his old ones less. He’d ignore his old friends that would say that Kate was no good, that she wasn’t in it for the long run.
The final thing she started to ‘take care of’ was integrating herself into the Hale family as a good girlfriend. She knew that Derek’s older sister who also lived in New York was weary of her thanks to the age gap and shady background behind the Argent name, so Kate made sure to make a good impression whenever any of the Hale’s came to visit. Derek thought she was the perfect girlfriend, being pleasant and friendly with his family while being sexy and dominating behind closed doors. He had the best of both worlds. Kate was prepared to do this in the long run, itching to get her hands on Derek’s share of the Hale family fortune one day that was sure to set her up for life while her own family’s wealth was dwindling.
Derek, of course, didn’t suspect that Kate didn’t truly love him the way he loved her.
Now, just under two years since they’d first met, Derek had gone from being a young fratboy who liked to party and didn’t care how he dressed to having a title at one of the most –if not the most- influential fraternities at NYU, wore suits and slacks and polo shirts and attended gala dinners. Kate had to hand it to herself, she’d done well with her little pet project. Having Derek living with her this year and having him as her TA was the icing on the cake, making him more dependent on her than he’d ever been, and he didn’t even notice.
Also thanks to her father and his connections at NYU, Kate had managed to take over from Professor Fink after he’d retired so now she was Professor Katherine Argent. People on the teaching body were of course suspicious of how Kate had managed to literally walk into a prestigious job at her Almer Mater so soon after finishing her own degree, but wouldn’t look into it because of Gerard Argent’s generous donations each year and how close he was to the Dean of the university. Kate was setting herself up to have the best life.
~ ~ ~ ~ ~
Derek was in the class before Kate arrived, sorting out her papers and the power point he’d helped her prepare a few days ago for the Intro to Latin class for freshman students hoping to pursue History and Fine Art. Derek was looking forward to helping students out in the class, seen as not all of them had any knowledge of the Latin language. Being a pro himself, he liked the idea that he was in a superior position to the students as well as being a helping hand to them if they needed it.
He had just finished separating the hand-outs for the class when he heard the door swing open, a flustered student rushing through them in fear of being late. Derek looked up at the boy, whose hair looked like a bird’s nest, sticking up in every direction with his cheeks flushed. The boy was dressed in a loose batman tee and baggy plaid shirt, bag swung haphazardly over his shoulder. Derek sighed, a smile forming on his lips as he shook his head. Of course Stiles would make it in the class before Kate by the skin of his teeth on the first day.
The boy –Stiles- looked around the room in panic before his gaze locked on Derek, mouth open a little and breathing heavy. Derek rolled his eyes at the younger boy and pointed at the selection of seats, motioning for him to take one as Kate strode into the classroom like she was on a catwalk, hair flowing over her shoulder as she swayed her hips with each step. Most of the guys looked at her with lust, the girls with jealousy. All except for Stiles, who rolled his eyes as he took a seat just above where Derek had placed his things and to the side.
Derek knew Stiles from Beacon Hills, where they’d both grown up. The Hales and Stilinski families were close with Stiles being an honorary Hale nearly all his life, spending nearly every day up at the Hale house. Derek’s younger sister Cora and Stiles were the same age and had been best friends their entire lives but it was Derek and Stiles that seemed the closest, with Stiles seeming to look up to Derek and go to him for advice about anything. Derek was the first person Stiles confided in that he thought he was gay during his sophomore year, and since then Derek had gone to jungle with the younger boy a few times when he’d been home and in general looked out for him. When Stiles had told Derek he was thinking about coming to NYU to study, Derek had helped him with his application and he’d even helped sort out a dorm for Stiles when he got accepted. Derek’s mother had told both he and his sister Laura to look out for Stiles, but neither of them needed the reminder. Stiles was family.
“Salve, class!” Kate said seductively, her voice carrying through the big lecture hall. The guys were all hanging on her every word, all of them except Stiles who didn’t seem impressed with her. He leant down so his lips were at Derek’s ear.
“This is the hot piece of ass you’re dating?” He whispered sceptically.
Derek didn’t respond, he merely sat back and watched Kate parade around in front of the class and introduce the module to her students, outlining what was expected of them this semester and throughout their time at NYU.
“And this, ladies and gentlemen,” she purred, gesturing at Derek, the girls in the class all snapped their heads to Derek, jaws dropping, “is my TA. His name is Derek Hale and he’s a senior here at NYU, majoring in Classics. He will be your link to me and be marking most of your assignments. If you need any help on the module, you can go directly to him with any queries. His office hours are on the screen behind me, along with his contact details if you would like to write them down as I won’t be giving them out again…”
Suddenly, all the girls rushed to write down all the information on the board. Derek could hear Stiles snickering behind him.
“Looks like your lady has some competition.” He muttered, nodding at the flash of disdain on Kate’s face at their enthusiasm.
“There’s no competition, Stiles.” Derek replied, smiling and waving at the class before turning to Kate and giving her a loving, sincere smile.
Kate didn’t have time to react to it as the bell went, signalling the end of the class. All of the guys except Stiles swarmed to Kate, while the girls went straight to Derek. Stiles lurked at the end of the group of girls, a little amused at the attention his friend was getting.
“Mr Hale? I was wondering if you did tutoring for Latin? See, I’m not too good…” One girl murmured, sticking her chest out in Derek’s face. Stiles muffled a laugh, causing some girls to turn and glare at him. Unbeknown to both of them, Kate was watching the exchange while talking with an over eager student named Matt who had apparently read her dissertation on Latin culture and wanted to ask her about it.
“I’m afraid I don’t have time this semester for tutoring. I’m sure some of your other students might be able to help you though.” He replied, his gaze on Stiles with an eyebrow raised. Stiles shrugged.
The girl huffed and made her way out of the class, followed by most of the other girls that obviously wanted to know the same thing. When they had all left, Stiles gravitated towards Derek, books in hand and bag on his shoulder.
“Yes, Stiles?” Derek asked, exasperated.
“Huh? Oh. Laura’s taking me to see her exhibition this weekend. She told me to remind you about it and that if you even think of missing it, her next collection will include pictures you never want the world to see.” He teased, winking before he made his way to the double doors. “See you later!”
Soon enough, the room was free of everyone but Derek and Kate, and Kate wasted no time, pinching his ass in the fitted trousers she’d got him.
“Seems like I’m not the only person that gets distracted by you.” He purred, a harsh undertone in her voice that Derek didn’t seem to pick up on.
“They’re barely 18. They don’t know what they want.” He countered, turning his head to her with a small smile on his face.
“But you liked the attention, didn’t you?” She accused; a hint of playfulness to her voice that sounded a few octaves too high.
“It was weird. I’m not…used to it, I guess?” Was all he could say as he packed up his satchel.
Kate hummed, her hand going over his shoulders once more before she gathered her things and they left together.
“I’m assuming the kid that was stuck to you all morning is the family friend. Giles, is it?”
“You mean Stiles? Yeah. I’ve known him all his life, practically grew up in our house. What do you think of him?” Derek asked.
“He didn’t really seem interested in what I had to say, seen as he spent most of the class giving you a commentary. Not to mention the fact he almost ran me over charging into class just before it started.” Kate commented, not pleased.
“He’s always been a little jittery. He finds it hard to focus.”
“He seems to think he’s above my class, and we haven’t even started.” Kate remarked.
“He doesn’t, he’s just adjusting. Give him time.” Derek reasoned, although Kate didn’t seem that convinced.
“Yeah, well. We can’t spend too much time at your sister’s exhibition this weekend remember? We have the dinner at my family’s house to celebrate my first week as a professor.”
Derek cursed. He’d forgotten about that.
“I could go to Laura’s exhibition alone if you want? Give you the time to get an outfit and get ready and then I could stick around at the gallery a little longer before meeting up with you at Gerard’s.”
“It’s black tie, Derek.”
“I can bring my suit with me to the Gallery and change in Laura’s studio, it’s not a problem.” Kate stopped, eyes narrowed at Derek.
“…Fine. But if you’re late, my father will not be happy. At all.”
Derek pressed a chaste kiss to her cheek. “I won’t be late, I promise.”
“You better not be, or there’ll be hell to pay.”
~ ~ ~ ~ ~
Derek was definitely going to be late.
“Fuck!” He yelled, slamming his fists into the tattered backseat of his taxi. He was ten blocks from Gerard’s apartment, it was 7:05 and traffic was backed up thanks to an accident. He was honestly contemplating getting out of the taxi and walking –running- it, but then he’d be late and not presentable. He tried calling Kate’s cellphone yet again, and was met with no answer. Derek leant forward in the cab towards the driver.
“Look, how much longer do you think it’ll take?” He asked.
“By the looks of things…a good half hour at least, man.” The driver replied, tapping his fingers on the wheel. Derek looked out the cab window at the empty streets and then at the traffic miles ahead of him.
“Fuck it. I’m walking it. How much do I owe you?”
The driver tapped his meter. “$23.”
Derek opened his wallet and took out two tens and a five. “There. Keep the change. Thanks.” He handed the money over and got out of the cab and fished through the traffic to the sidewalk before he started to jog, which before long turned into him sprinting up the rest of York Avenue until he got to East 79th Street.
When he finally got to the door to Gerard’s apartment, his hair was dishevelled, shirt untucked and tie partially undone, he quickly attempted to fix it before looking at his rolex watch –a gift from Kate- and saw that it was 7:18. He was 18 minutes late. He knocked on the door and prayed Kate wouldn’t kill him for being late.
Of course, she was the one who answered the door, face like thunder.
“You’re late.”
“I know, I’m sorry bu-”
“No excuses. You promised me you’d be on time.” She said , cutting him off.
Derek’s shoulders slumped.
“I’m sorry, I really am.”
Kate narrowed her eyes at him and looked him up and down, expression not changing or wavering before she opened the door more and let him come in without another word.
Gerard appeared behind Kate as Derek entered with his head down, obviously judging Derek for his lack of punctuality.
“You’re late.” He remarked.
“I know. I’m sorry.” He said again, sounding more defeated each time he had to say it. He knew that Gerard didn’t approve of his relationship with Kate and thought of him as just another college fratboy. He’d spent the last year bending over backwards for him and Kate to show he was worthy of dating his daughter, but nothing seemed to work.
During the rest of the evening at Gerard’s he’d received evils off all the guests that were at the small get together. What didn’t help matters is that his cell hadn’t stopped vibrating since Friday night with all his students emailing him already asking for help. After the fifth time, Kate had dragged him aside and told him to turn his phone off before Gerard threw him out; he’d already ruined the evening and it didn’t need to be ruined any more. He did as she said before handing it over to her to put in her purse. He was so screwed when they got home.
When they got back to the apartment, went straight into the spare bedroom that they used as a study and closed the door in Derek’s face. Hurt, he went into the bedroom and changed into the one pair of sweats he owned before heading into the kitchen to grab a drink and something to eat; he hadn’t had time all day to get any food because he was at Laura’s exhibition as a supportive brother –along with Stiles- and then he’d rushed to Gerard’s and the meal was nothing more than finger food.
Derek opened the fridge and saw all the greens and fresh foods that Kate bought and sighed, merely grabbing a bottle of water before raiding the cupboards and finally coming across a pack of dried ramen noodles and started cooking them.
During this time, Kate was pacing the study in her stilettos and LBD, still furious at Derek for showing her up. He was meant to do exactly what she said; he was her toy after all. She couldn’t believe that he’d turned up late and a mess when she’d told him explicitly not to. His phone going off all night, emails from those young, beautiful girls was the tip of the iceberg. Kate was jealous of the attention Derek had been getting off the girls all week, even if she understood why; Derek looked like a Greek God, sculpted to perfection and –thanks to her- wore well-fitted clothes. But Derek was hers, and she needed to show everyone that. There had to be a way to knock down his confidence and curb the attention he was getting, surely.
Kate could hear Derek pottering around in the kitchen, and stuck her head out of the door just a little to see what he was doing.
Derek was spooning the noodles into his mouth so fast; it was almost as if he was inhaling the food. Kate narrowed her eyes at the noodles, not knowing where Derek kept them. She knew that he had a secret stash of goodies somewhere in the apartment, since he had a sweet tooth and wasn’t always pleased with her low-fat-gluten-free meals. She’d let it slide because she knew if she tried to take it away, Derek would realise just how much control she had on his life. She was sure though, if Derek didn’t live by her healthy diet plan, he’d probably have a beer gut by now, and no one found that attractive.
Suddenly, an idea popped into her head. What if she let Derek eat more of the things he liked so much? What if she cooked him heartier meals; like lasagne and pasta dishes, baked him muffins and cookies. Then he’d appreciate her more, think she was bending over backwards to please him. She looked at her own slender figure. It was sure to do damage to her own body, but with a gym downstairs she could always sneak away for a few hours to keep in shape while he did her work for her at the university, and he’d be happy to do it. It would mean that Derek himself would have less time to go to the gym, make him softer quicker. A smile grew on her face. No one else would want him then.
She was going to make Derek fat.
