One More Night

Four

A/N: I love that you guys are enjoying this fic! And I know y'all are impatient about certain things happening rn but don't worry, everything will make sense eventually! Sorry for typos, I wrote this on my phone on vacation lol.

Also- there's a smut warning for this chapter :)

"You look sad," Erica observed, poking her fork into Derek's food as she leaned across the table. Derek frowned, but didn't stop her. She did it all the time, so really, he should have been expecting it by now. "Tell me why you look sad," she continued, waving her fork around with her piece of stolen chicken still on it.

"It's nothing," Derek lied, shielding his plate from her grabby hands before she could take anymore and make his night even worse. He thought today couldn't be worse than yesterday, when he found out Stiles had a girlfriend and Derek had to see the two of them together twice a week for the rest of the semester. He figured today had to be better. Of course, when Derek was on his way to get coffee between classes, he saw Stiles and Lydia sitting at the fountain together, all close and intimate. He hated the way it made him feel. He hated it even more when Stiles looked up and smirked at him. That fucking asshole.

"Clearly," Erica snorted, rolling her eyes. "Wanna try that again?"

Derek sighed, dropping his fork as he dragged his hands over his face in frustration. "I'm not sad, Erica. I'm just- I don't know, I guess I'm a little upset about Stiles." He didn't look at her as he said it, but he could just picture the smug grin on her face. She loved making fun of Derek about his boy problems and this was a completely new kind of boy problem. She was probably loving every second of this school boy crush thing Derek had going on with this guy.

"Are you upset because you want to be more than fuck buddies?" she wondered, surprisingly neutral when Derek finally looked up to meet her eyes. She raised an eyebrow, waiting for Derek's answer.

"No," Derek said too quickly, his face hot. "We're not fuckbuddies anyways. It was a one time thing." He felt like he was being too defensive and Erica was going to see right through him. She waited for him to keep talking so he could get to the point. Derek huffed, looking down at the table. "I'm upset because I found out yesterday that Stiles has a girlfriend. I'm their TA."

"What a dirty, lying, cheating pig," Erica growled, overly dramatic as usual. "You should tell his girlfriend! That'll teach him. What a fucking asshole!" She stabbed her fork into her plate, missing her food completely in her blind rage about cheating assholes.

Derek rolled his eyes. "I'm not outing anyone, Erica. As much as I want to tell her he's a cheater, I doubt she knows that he's into guys."

"Then don't out him," Erica replied with a shrug. "Just tell her you saw him with someone else."

Derek really just wanted to forget about Stiles all together, so he had no intentions of talking to him or Lydia at all. "She seems like a smart girl. She'll figure it out," Derek answered, making Erica scowl at him. "Look, I just want to get over the guy. I barely know him, so it shouldn't be hard. I need a distraction."

Erica's scowl disappeared, replaced by her sly smirk as she formulated a plan in her head. "I know a place that has plenty of distractions for you to choose from," she said, waggling her eyebrows suggestively. "We can go on Friday night."

Derek chuckled, shaking his head at his best friend. "Alright, you've convinced me," he agreed, without much reluctance at all. He really did want to get over Stiles, even if that meant sleeping with a random guy at a club. He had to get back to his old ways, before he ran into Stiles at that diner. Meaningless hookups that were far from the earth-shattering sex he happened to have with skinny college freshmen who may or may not have been from Derek's hometown.
