Chapter 2
Bucky found Sam nearly an hour later in the parking lot. He was sitting in his truck, slumped over the steering wheel with a cool bottle of water pressed to his head. He looked bad like he was coming down with something serious. It still didn't make sense why he ran off though.
"You okay, Sam?" Bucky asked gently.
"Huh, yeah I'm fine." He answered snapping out of his daze.
"Why'd you run off? Were you feeling sick? I would've looked for you sooner, but I didn't want to leave the boys alone."
"I just got a little overwhelmed, needed some air."
"Oh, well you don't look so good. And you smell...different."
"Pheromones man, they're weird like that." Sam said trying to move past the topic. He hadn't even realized his scent changed, he was too caught up in his head to notice. "It's probably just stress, you know how it is."
"Yeah, if you say so." Bucky replied not quite convinced. "Are you sure you're okay though?"
This time Sam didn't answer, he just huffed in exasperation wishing for once he'd just take his word as is. He knew the alpha was smelling his discomfort, his own body betraying him once again. The scent blockers he used always worked, always. And if they were a bit faulty, his suppressants were enough to ground him. Today, though neither helped. Bucky didn't brush against him or even accidentally scent him, the man just smiled at him and he went into heat. It was either that or his alpha scent was stronger than he was used to.
Sam wasn't ready to admit defeat. Hell, he never thought he'd have to experience a heat again. Yet here he was hiding out in his truck, imagining a big strong alpha knotting him full. It was so embarrassing, especially since it was Bucky of all people. It had happened with Steve before too, the pheromones of supersoldiers were always a bit too aggressive for him.
"Sam," Bucky started warily. "You're in heat."
"What- no." Sam denied it, his voice gone high in nervousness.
"I can smell it on you. It's strong and sweet." He moved closer breathing him in. "It's so sweet."
"I'm not in heat, okay. I'm not some useless omega." His words caused Bucky to pause. He looked up at him in shock.
"Sam, omega's aren't useless and neither are you. But you will be if you don't go home, you'll make yourself sick out here."
"Always the voice of reason, aren't you." He said lightly. "I'm fine Buck, just go away."
"I'm taking you home, so you can set up your nest and ride this out in a more suitable area. Then I'll get you some supplies if you need it."
Taking Sam's hand he guided him over to the passenger side door and helped back in the truck. He placed the water bottle back in his hand but his fingers brushed over his wrists this time, accidentally scenting him. It felt like his stomach had dropped, he had only meant to help and now he'd gone and made things worse.
"Shit, Sam. I'm so sorry, I didn't mean-"
The omega's whine cut him off, nearly tearing his heart in two. He'd never seen Sam so vulnerable, so scared. "Please," he heard him beg. "I'm fine, it's okay."
"No," Bucky growled feeling overprotective. It had been a while since he'd scented anyone, he couldn't help his feelings from coming out so aggressive. "Let me help you, please."
Sam was finally back home, situated on his bed between mounds of pillows that Bucky had collected for him. He hadn't even remembered coming home, let alone making it to his room. He hadn't had a heat in years, even then they were few and far between. He was scared, absolutely terrified of what this meant now that Bucky knew. He'd seen him at his lowest, whining and begging like the omega he never wanted to be. Everything had been going so well and he messed it up just like that, he couldn't believe it.
"Sam," A voice called from the hallway. "Can I come in? I brought you something to drink, you need to stay hydrated."
"O-Okay" He choked out, his voice full of emotion.
"I wasn't sure if you wanted juice or water, you were kind of gone last time I-" Bucky stilled noticing Sam's face. He looked so sad, his eyes on the brink of tears. "Oh, what's wrong?"
"I'm sorry. I-I didn't mean to hide it from you, it just was easier this way."
"Doll," Bucky said gently. "I'm not mad, not one bit. I'm not going to judge you for something like that, so don't cry, okay."
"But-"
"It's okay, you're okay. Now, drink some water."
