random abo thought: alpha!caleb x beta!reader but in this omegaverse caleb distraught cause his mating mark fades after his ruts but still loves her regardless. he reads somewhere where alphas can turn others into an omega by giving them their cvm consistently (drinking it or whenever they sleep together idk). one night when he’s about half asleep, he hears his door open and its reader and the room is filled with a almost sickening sweet caramel apple scent. reader climbs on his lap straddling him unknowingly dry humping him while panting against his neck whimpering quietly for him to do something and how she feels hot and needs him….
i think that this would be exceptionally funny if reader was never a beta but just a very late bloomer who was never genetically tested for her second gender and caleb thinks that actually he's entirely responsible for this biological change he found out about on reddit.
like maybe reader just didn't present until she's over 20 years old, which is exceptionally rare, but completely possible. it just happens to coincide with caleb being delusional about giving reader creampies to change her biology.
there's also the possibility of granny josephine keeping reader from presenting with medication that she's been giving you since you were 14 or so, and now that she's gone, she's not reminding you to constantly take it. you never go looking for the prescription and it naturally leaves your system. as soon as caleb comes back, his pheromones send you into a super delayed presentation.
either way, caleb would be soooo ridiculous about the whole thing. he'll bring up to you what he saw online after your first heat had passed, and your mouth will drop to the floor. how can a man as smart as caleb fall for some weird 4chan bullshit? a 50$ bet is placed. you consult zayne. you're genetically tested. you always were an omega. you are 50$ richer and caleb has a very bruised ego.
