just thought of a/b/o hucklabbot bio!son omega dennis/bio!dad alpha jack
dennis is a product of a one night stand, his mother gave him up for adoption and was adopted out in nebraska
not having any blood relatives dennis never really gets to have the experience of being able to scent out family/blood in people.
fast forward dennis at ptmc, jack walks in immediately smelling family.
idk how sleaze you wanna make jack. option one he never tells dennis, option 2 he tells him straight off the back and dennis initiates, or option 3 jack doesn’t tell dennis at first but after 6 months of dating he does
WAIT OMGG WAIT option 4 knotted and claimed dennis gives birth to their pup and immediately gets a whiff of what he smells on jack and he asks about to the nurses why she smells like that, they tell him that’s just the familial scent. he connects the two things
your mind twin- YOURRRR MINNNDDDDD TWINNNNN
He's sleazy. The sleaziest. So sleazy that he Knows from the second he smells Dennis that he's a blood relative of some kind and easily deduces within a day that he's his son by Dennis' age and how strongly he reeks of kin. He's such a sleaze ball that he intentionally scents Dennis multiple times the first day he meets him and keeps complimenting his scent -sweet corn, confederate jasmine, lemongrass, and birch- just to make Dennis preen and push out more of it, and Jack does the same with his own scent -black tea, ginger, bergamot, and poplar- for the sole purpose of soaking some of his oil into Dennis' clothes, forcing Dennis to smell him all fucking day.
It gets to the point where Jack is making sure to rub up against Dennis at every shift change, taking his scent patches off early so he can wipe a hand down the side of his neck to collect the oils then smear it across the Omega, maybe on his skin, maybe on his scrubs, maybe even through his hair, it all depends on how possessive Jack feels that day. I'm sticking with my Jack Abbot Has A Scent Gland Abnormality headcanon here so he REEKS without his patches and easily secretes enough oils to leave a sheen on his palm when he swipes over them, it's enough to stain his clothes if he lets it go unmanaged for just an hour.
And Dennis fucking loves it so goddamn much but doesn't get why. He's never been this drawn to someone's scent before, there's just something that twinges in Dennis' nose whenever he gets a whiff of the older Alpha's scent, it makes him all fuzzy headed and calm. It makes him feel like he's safe even in an ER with strangers filtering in and out constantly. He starts presenting his neck to Jack only a few days after meeting him because he expects the Alpha to scent mark him for the entire ED to know who they're going to answer to if they fuck with Dennis.
-ooo aaa time skip, they'd been fucking/dating for about a month now
Dennis is at some sort of secondary-sex doctor's appointment to get his birth control implant renewed, and they're asking him if he's sexually active, and if yes, then does he feel safe because something something adverse effects of the hormonal implant, you get the gist. And ofc Dennis gets a little bit stuck in his head thinking about how incredibly safe he feels with Jack, especially when underneath the older Alpha and they're tied together and Jack keeps carting his fingers back and forth from where they're locked together and their mouths, collecting all the slick and cum that's leaking out around his knot and having Dennis suck it off his fingers before he's kissing the boy silly. Dennis has to cough into his elbow to cover up his whimper from the memory of Jack's words.
"That's our taste, baby boy; that's our smell, too."
Dennis asks if there's a reason he and Jack smell a certain way, and the nurse misinterprets it to mean only when they're having sex.
"Without sending off a sample of your coupling fluids to a lab, I can't give you a concrete answer. But what you're describing is tracking the lines of an Omega preemptively creating the new familial scent that your pup would carry, even if there's minimal possibility of the Omega getting pregnant. It's natural, and the new scent can really help unify a bond between Alpha and Omega, and make your Alpha feel more like family going forward." The nurse rattles off, smiling at Dennis' chart as the Beta types away, oblivious to the heat spreading all throughout Dennis' body.
"Right, okay, that makes sense-" no it doesn't. Because Dennis always smells that thick underlying layer of musk on Jack. From the very first day he was carrying that scent and it had Dennis questioning everything about himself. It's not new.
-ooo ahhh another time skip, Dennis is at home
"How'd your appointment g-" Jack can't the full question out before Dennis is tugging the sleeve of his shirt down and burying his nose in Jack's armpit, snuffling at the scent glad there and breathing through his mouth at times, clearly trying to saturate every inch of his olfactory system with the Alpha's scent.
"We're related-" Dennis presses his face in harder, claws digging into Jack's side where he's keeping the Alpha still- "somehow. Nurse said that's what 'our smell' is-" if Jack couldn't see the boy in front of him, he'd think there was a very curious Rottweiler huffing at him- "but you always smell like that."
There's a grin plastered to Jack's face when Dennis finally comes up for air.
"Oh, son. I was waiting for you to figure it out."
