Antidote [18+]

Once

Xander stared at the sleeping boy beside him. He ran his fingers through Seth's hair and admired his features. A smile crept on his face as he thought about the fact that he was Seth's and Seth was his.

He pressed a kiss to Seth's forehead and pulled him closer to his chest. 

"Mmm," Seth groaned pulling the blanket over his head.

Xander smiled to himself and slid out of the bed and padded to the bathroom. Warmth spread through Xander's chest at the thought of  everything that had happened with Seth. He wanted this relationship more than anything but he wasn't going to push Seth, knowing that he was still finding his sexuality. 

"I don't think the reflection is gonna change if you stare that hard," a raspy voice said. 

Alex turned around and faced him, "Buen día cariño."

"What now?" he said rubbing his eyes. 

"You're so cute in the morning," Xander said pulling him forward.

Seth rested his head on Xander's chest and closed his eyes. He wanted to live in the moment. No worries about what anyone would say or do if they saw them together. 

"Seth," Alex said with a mouth full of toothpaste.

He opened his eyes and he returned to reality realizing that someone had been knocking at the door. Who the hell could that be at 11 on a weekend?

Seth opened the door to reveal Hadley Romanetti, his sister.

"I just came to see how my little brother's doing."

"You should've called, I didn't know you were coming back from Athens so soon," Seth said.

"Seth, have you seen my goggles?" Xander said walking into the room, "I'm almost sure-" he paused upon seeing Hadley. 

Hadley took in the grey sweatpants hung low on the hips and the well defined torso above it, "Hello there."

"Xander, my sister Hadley," he inroduced, "Hadley, this is Alexander Vargas."

"Nice to meet you," Xander smiled reaching forward to shake her hand.

"Likewise," she grinned, "I thought you stopped inviting friends over?" 

"Xander is my-" Seth scratched his head nervously.

"Friend from school," he filled in for him, "Seth's letting me stay over for a few nights because his house is closer to the hospital."

"Oh, you're in medicine?" she asked

He nodded, "I am."

Seth couldn't bare for this conversation to continue, "Alex, your goggles are in the bathroom."

He saw the slight twitch in Seth's eye, "It was nice meeting you Hadley, I need to go pack my bags for swim training."

"You too Alexander," she smiled as he disappeared into the bedroom.

Seth let out a sigh of relief, "Why  are you back so soon?"

"To snatch him, what else?" she smirked in the direction of the bedroom. 

Seth felt the irritation rising now that his sister was obviously attracted to Xander.  The fact that they weren't exclusive didn't give him any lock down on Xander and the thought that he was bi-sexual made it even more irritating, the possibility of girls stealing him away.
