When Peter first walks into the compound, Tony is nearly blindsided by the smell.
It's bitter, so sharp and striking that the billionaire flinches back, dropping the screw driver in his hand and whipping around. His pup stands in the doorway, his doe eyes wide as he comes to a sudden halt.
SCARED PUPPY. MUST PROTECT, KEEP SAFE.
"Hey, Dad." Peter says, adjusting his backpack straps. "Wh—"
But Tony cuts him off, stalking over and gripping the teen's shoulders. "Why do you smell like that?"
"L-Like what?" The smaller Omega stutters and Tony grits his teeth.
"Don't lie to me, Peter." The genius nearly snarls, leaning down and pressing his nose against his child's curls, breathing in his sweet scent. He feels Peter snuggle closer in response. "You smell scared, and I'm not leaving this alone until you tell me what's wrong."
Peter sighs, his small body trembling and Tony can't keep his growl quiet this time. It shakes his chest, rumbling up from his throat and the omega swallows down the rest of the sound when the kid finches a little against him.
"It's nothing." His pup finally says, his scent stuttering in nerves and Tony grips him tighter. "I p-promise."
Releasing Peter with a small huff, Tony glances down at his son and frowns when Peter won't meet his gaze. Gently tapping Peter's chin with a knuckle, Tony waits until the boy looks back up.
"Okay." Tony says, a soft rumble filling his chest when Peter deflates. "Okay, kiddo, I believe you. Let's work on some stuff and try to calm down, alright?"
Peter nods, moving backwards and dumping his backpack onto the chair next to his work bench. Tony watches him for a second, eyes softening, before he leans down and picks up his screw driver once more, going back to his project and listening to the nearly silent sound of his child's breathing fill up the space.
It's nearly 10 minutes later when Tony smells something that makes his blood go cold.
Blood.
The coppery scent rises up and Tony's nostrils flare as he staggers, turning around so fast he nearly falls and makes it over to Peter's side in a split second. His pup is leaned over a blueprint, his baby face creased in concentration, an expression Tony would normally find adorable if not for the fact that the Omega's instincts are currently screaming at him.
