Scott's never been much of a biter. Growing up, his mom had mentioned offhandedly that he'd never even had that long of a teething phase, growing bored of biting everything way sooner than everyone else. So, clearly this information counts as reasonable evidence to assume that he just wasn't someone to bite.
Especially after the turning, becoming a werewolf meant that he had to always be conscious of his bites with everyone he dates. Careful, Cautious, Alert. His new teeth, sharp and jagged and meant to tear, weren't something Scott would ever use on people.
That was before you. When he'd started dating you, he feels like he's teething again. Like some puppy that needs to bite on everything he can possibly get his hands— correction, his teeth on. Whenever he's alone with you he cannot keep his mouth off you. When you laugh Scott has the urge to nip at your jaw, or when you brush hair out of his face, he wants to bite gently at your wrist just to see the small indents in your skin.
Don't get him started on your neck though. Whenever Scott's alone with you he's always biting at it, gentle enough to never tear skin but always leaving behind imprints that'd last for a few hours, before he'd go back in and replace them. "Mm.." he whines lightly when you tug him up, away from your neck. His teeth are out, just about to start biting.
His mind is so so fuzzy around you. Whenever you're around and he can get his hands on you, inhale that scent of yours and get his hands on your neck, he's just a mess of an Alpha, all whiny words and nipping teeth. Scott would be more embarrassed if his head wasn't so dizzy around you.
"What?" he can see that look in your eyes, lightly teasing, amused that he was biting at you again. "No, 'm not teethin'," Scott grumbles, already sensing your words. He definitely was, if your body was any marker to go off of. Scott tilts his head down, burying it back in your neck. "J'st instincts." He insists.
