His mind was doing bad things. Well, it had done bad things before but now it was just going batshit crazy. His brain had turned full on criminal and he couldn't stop it because it's not his fault Lydia looked so damn good in a bikini.
The installation of a new in-ground pool at the Martin household called for a first time swim with the entire pack and no one had turned down the idea, especially with the scorching summer they seemed to be stuck in. But one thought left Stiles sick in the stomach as he suddenly realized on the drive over that for the first time ever, he would see Lydia in a bikini. It was different than seeing her in lingerie while drugged up after seeing Peter Hale go full wolf and it was different than seeing her naked after her little run-around in the woods. He didn't know why, but it was just different. The more he thought about it, the more he had to adjust his swimming trunks on the way there.
Only when he arrived did he realize he was late. Scott, Kira, Isaac, and Malia were already playing volleyball in the pool, Liam was shouting at them with his feet in the water, sitting on the edge, and Derek was either taking a nap or was full on comatose on one of the yellow striped lounge chairs. Stiles entered the backyard through the open side gate and immediately Scott spotted him, picking on him for being the last one to show up and telling him to hurry up and get in the water so Liam could join their game (because apparently Derek didn't want to go anywhere near the volleyball). He laughed and tried to ignore the thumping in his chest when a hand brushed his bare back as Lydia passed by him. She came from the house, carrying a tray of bottled Lemonades towards the group while throwing a smile and a "glad you made it" over her shoulder at him.
God he felt sick. She was so innocent or at least she was acting so innocent, not even bothering to take a look at his bare torso only partially hidden by the towel that hung off his shoulder. But his jaw nearly fell off. The bikini was a light paisley green and made her hair a brighter shade of strawberry blonde and if he didn't know any better, he would've thought it was merely painted on, the thing was so skin tight. He was screwed because his mind kept flashing images in his head, bad images, dirty disgusting things that one shouldn't think about their friend but oh man, Stiles was nearly dead anyway.
His mouth felt dry and when he tried to swallow, he nearly choked on the air he was forcing himself to intake because he kept on having to say breath over and over to himself and he was still standing in the grass in the middle of her yard just doing nothing and–
"Stiles, want to be on my team or Isaac's?" Scott called, interrupting the panic he felt swelling up in his chest.
"What kind of dumbass question is that?" He forced a laugh that he hoped sounded genuine and finally made his way towards the pool. He slipped off his sandals and threw his towel on top of them before jumping right in the water on Scott's side of the net. Kira and Malia shrieked and Isaac cackled when Liam fell in, splashing the beta when he came up for air.
From the corner of his eye, he saw Lydia in the lounge chair next to Derek's, making small talk with him. He was jealous. Not because Derek liked her or because he thought she might like him (he knew she didn't) but because they were talking. He wanted to talk to her. Screw Scott, screw the volleyball game. But he didn't want to seem desperate. Would that seem desperate? He was overthinking it all.
They played until Stiles and Kira kept eyeing the lemonade Lydia had brought outside when he first arrived. Everyone agreed on a timeout and Stiles was the first to jump out of the pool, jogging over to Lydia, the beverages on a Small table to her left. He chugged down half of the lemonade, his shadow blocking her sunlight as he dripped over her. Lydia tilted her head back to look up at him as he screwed the lid back on the bottle.
"Get in the water." He used his chin to point at the pool, choosing to tell her rather than offer the activity as an option. Kira snuck an arm around his back to grab her own lemonade but she chose to slip back into the pool as she drank it, offering Scott a sip. Lydia adjusted one of the straps on her top.
She shook her head. "I'm working on my tan."
"Lyds, what's the point of having a pool of you wont even swim?"
"I'm fine watching the game."
Stiles sighed. "Wrong answer."
It happened so quickly that she couldn't properly react besides screaming to be put down, but somehow she had ended up curled over Stiles' shoulder. Her ass was in his face and he fought the urge to give it a light tap. He fought it so hard.
"STILES STILINSKI DONT YOU FUCKING DARE!" She screamed but he didn't care and he told her that before throwing her in the water. He laughed, cackled, nearly fell on the floor as tears formed in his eyes and when he finally chances a look at her, she was fuming. The girl appeared so hot, in fact, that he was surprised the water around her hadn't boiled. While she climbed out, Stiles climbed back in, still chuckling under himself.
