Stiles is putting his lacrosse gear on for morning practice when the first wave of nausea hits him…hard. He barely makes it to the stalls before he's emptying his breakfast into the toilet. He dimly registers that Danny, Jackson, Scott and Isaac are shouting and pushing their way through the crowd of players to get to him. Isaac is the first to get there.

"Stiles, you okay?" Isaac asks quietly kneeling down next to him. Stiles just groans before dry-heaving into the toilet again. He hears Jackson yell "Move the fuck along, nothing to see!" and then there's a hot hand pressing against his neck.

"C'mon. You stink of vomit." The co-captain says gently pulling Stiles to his feet. The teen just sags against him letting himself be dragged into the showers. He lets Danny pull the gear off of him and then lets Scott push him under the stream of water. Stiles just stands there in his boxers letting the cool water slide over his body. And then Coach Finstock is barreling into the locker room yelling for everyone to get their asses out onto the field.

"Whoever's in the shower, get the hell out, put your gear on and get to the field!" Bobby Finstock yells walking to the back of the locker room. What he sees makes him pause before shaking his head and muttering, "I'm not gonna even ask."

The water turns off and there are gentle hands on his hips leading him towards the bench by his locker. He gets told to sit and just breathe through the lingering nausea. The locker room door shuts with a bang and then opens seconds later with a squeak. Jackson appears with 2 cans of Ginger Ale and a packet of crackers.

"I called my mom and she said to eat the crackers and sip on the Ginger Ale." Scott says softly wringing his hands and for the first time, Stiles notices that they're all looking at him like he's some sort of object that'll break easily. He knows he's joked about being 147 pounds of fragile skin and bones, but it's nice to know that they still worry about him. So he takes the crackers and nibbles on it while trying to figure out what made him throw up.

"Stiles, maybe you shouldn't play today. I'm sure coach will understand." Danny states when he's finished eating the crackers and is on his second can of Ginger Ale.

"But-"

"No! You're not playing and that's final!" Isaac growls out shocking the other 4 boys into a short silence that Scott breaks with a murmured, "Derek would kill us if we let something happen to you." Stiles groans pushing off the bench to follow his pack mates as they walk out of the locker room.

"Dude, it's not like I'm pregnant! You know the chances of that happening are slim. My doctor said so when I went for my first check up!" Stiles yells ignoring the looks he earns from students that are at school early for some reason or another. He pauses when the werewolves and Jackson look at each other before walking even faster. "OH MY GOD!" Danny looks at him in alarm before Scott, Jackson and Isaac are hurrying back over to him when they hear his heartbeat escalate.

"Calm down. Please." Jackson says softly when the teen just looks at him with something that looks like happiness and a bit of amazement in his eyes.

"So, what you guys are saying is that I'm-" Scott cuts him off with a look.

"That's what it smells like, but we won't know for sure until your doctor and Derek confirm it. So you are going to call Doctor Sanders right now and make an appointment to see her after school. If you don't I will call my mom and have her make the appointment. Got it?" Stiles gapes at his best friend for a moment and then nods lowly. It's like he's on autopilot as he grabs his phone from his pocket, scrolls through his contacts until he finds Dr. Sanders and waits until she picks up to make the appointment. When he's finished, he walks out onto the lacrosse field and over to his bench –that's what he's started calling it— since he can always be found sitting on it during a game. When coach asks him why he's not running like the others, Jackson jogs over and says, "He isn't in the best condition to run, Coach." Coach Finstock just looks between the two of them, nods and then goes to yell at someone else.

"I texted dad and told him what happened. He wants you to call. But he said that if you don't call, he's gonna stop by." Isaac says slowing down to a brisk walk so that he can get the message across. Stiles grabs onto his arm, tugging him to a stop.

"Wait! What? Why?" The teen demands flailing his arms slightly; Coach glares at him.

"Bilinski! If you're not gonna run, stop distracting my team!" Finstock demands blowing on his whistle.

"OH MY GOD! It's Stilinski!" Stiles looks around the field when he notices that some of the players are looking at something, no wait, make that Derek, walking towards them. When he stops in front of them, Derek glares at his Betas.

"Why's he freaking out?" Derek asks looking from Isaac to the teen in question. His eyebrow rises slowly when no one answers him. "I'm pretty sure I just asked a question, one of you gonna answer it?" Aaaand he's using the Alpha voice. When Scott tries to move away without being noticed –major fail- Derek grabs onto the back of his neck in warning.

"Yeah, I'm not doing this in front of the entire goddamn lacrosse team." Stiles mutters walking back towards the locker room. When he looks back and sees that Derek's just standing there, he says, "Look, you can either hear it from me or from someone else. But I'd prefer being the one to tell you." Stiles just rolls his eyes when Derek looks at each of the pups and then at him before walking over to him. He's also still aware that the team is looking after them in confusion and that it only gets more confusing when Scott, Isaac, Danny and Jackson drop their lacrosse sticks to run after them. Derek pauses and then tilts a little to the side letting Isaac tumble onto the grass, but just as he goes down, he's back on his feet laughing. Scott tries to take a shot at him by coming in from his right side while Danny comes at him from the left and Jackson tries to tackle him from behind. He just sidesteps both Danny and Scott and grabs Jackson in a headlock.

"More practice. But you're all improving." Is all Derek says smirking. Stiles is shaking with laughter when they all look up and in 0.2 seconds flat he's lying on the grass clutching his stomach, laughter bubbling out of his throat.

"Dude." Scott says warily his gaze flickering from the teen's stomach to Derek. Stiles sighs pushing up onto his elbows to look at his best friend.

"I'm not gonna hurt myself from laughing. You're already worse than Der and he doesn't even know. And it could just be, ya know, the flu or something. Just cause I threw up in the locker room doesn't necessarily mean I'm-"

"Hold up. What don't I know? And when did you throw up?" The words are close to a growl that has Stiles jumping up onto his feet, grabbing onto the Alpha's arm and tugging him towards the locker room while the other boys follow closely. Nothing suspicious about this at all. Stiles thinks ducking his head when Matt passes them in the corridor leading into the locker room. "Talk. Now."

"Um. I threw up like 20 minutes ago and Scott made me call my doctor to make an appointment with her or he'd have his mom make it. And they," Stiles motions to Isaac, Jackson and Scott. "Said my scent smells different cause Imightpossiblybepregnant." The last few words are so rushed, Derek has to take a minute to decipher them and when he does, he casually sniffs his boyfriend -and how is that even normal?- and his eyes widen when he catches the subtle change in the boys scent.

"When did it start?" There's a barely there tone of shock in his voice when Derek speaks. Stiles just looks at him rocking back on his feet. "Stiles."

"Last week." The 18 year old mumbles looking down and picking at a loose thread on his hoodie. Derek makes an odd noise in his throat; something between a laugh and a groan. "What? No groaning! If I am, you should be happy!"

"You are and I am. But your dad's gonna kill me."
