omegaverse!Hilson, but—
...it's omega!House and beta!Wilson.
House was disguised as Beta and Wilson gets suddenly changed into having rut and becoming an Alpha while helping House in his heat (the first heat after years).
After that long week of heat and rut, they have to talk about their relationship and going to the next level/round of relation as they're now also expecting a pup from the possibility.
They also have to prepared House of his medications. Getting rid of the pain killer drugs. Detoxing him. Delayed heats and pregnancy was risky for House while he's also close of having menopause. [Uh-hm. This trope.]
Did I say pregnant!House? Because— why not? Exactly.
Being Beta is easy. They don't have to deal with the power of Alphas trying to make others weaker than they are; beta are basically isn't affected at all. The also don't have to deal with loosing their mind over Omegas; beta are basically wouldn't affected at all.
House, on the other hand— could still smell pheromones, having the physicality of an Omega, but that doesn't affect him; only for him to detect emotions and symptoms.
The first heat after delayed years that House was having is intense. His beta medication couldn't even work the slightest. He is one of the eldest doctors in PPTH. Menopause has already been in his mind while taking the disguise-medications after all of those years. He should've expected this anomaly, but he won't believe it; he's still hoping this wouldn't be happening.
And yet, it happened. It happened and he's affecting Wilson; turned the Beta into Alpha. The new Alpha grows even stronger when he already was as a Beta. Wilson is physically adapting to the needs of his Omega. The Omega is fearless; he has to protect him. The Omega is energetic; he has to calm him. The Omega is having a bad working leg; he has to be strong enough to carry him. His "House feelings detector" is even more heightened now that they've become mates.
They're growing to even more domestic to each other. Having House on top of his chest when he's waking up is one of things Wilson loves. Seeing House's eyes opened up when then House getting up his head, facing him. Those dreamy blue of the sea in House' eyes screams home for Wilson. House sometimes waking up with grunts when it's a direct sunlight greeting him at the mornings. Wilson doesn't mind of waking up later than he was usually do.
Wilson is having the scan of their pup in House belly for his lockscreen; updating every time they got new check up on House. He picked House pictures himself to put it on his devices' wallpaper.
This probably is Wilson's one of his favorite pictures of House. He got it from the CCTV. He put it as his laptop's wallpaper. Once, he was presenting a powerpoint with his laptop to a medical conference for doctors, nurses, and medical students; suddenly the .pptx was closed and showed them this picture of House. He could hear the gasping sounds from the audience.
"Please, don't tell him. He's gonna kill me."
Words fly. The capture was somehow received by House. House was embarrassed. But, that doesn't mean he doesn't like it. He likes it, but he's feeling embarrassed. At first, Wilson worried that House would snapped on him about the picture. But, it doesn't seem like House hating it, so, his heart became warms. House confronted him when Wilson came to House' office, inviting him for lunch. So, when he saw that bright red color rises to House' cheeks, Wilson leans down to put a kiss on his forehead, then squatting down to meet his belly. Telling the pup that House was getting embarrassed, getting a gentle slap from House to his shoulder, then he also put a kiss on House' belly.
Going through pregnancy absolutely not easy for House, while also he's detoxing. His PPTH fellows are supporting him so that he still could working as the head of diagnostics department, making it managable for him and the whole team.
In their home, though—
House leg pain came when it's approaching the late nights. Wilson supports House with his growing belly. House was expecting Wilson to complain; either because of his neediness, his weight, his distress, anything. But, no...
Wilson doesn't ever snapped on him. He tried to listen to every complaints that House voiced, that House showed, even when House couldn't the both. Wilson could also feel the stress, but he knew he can't compare his to House's.
They're both anxious about what will come to them now they're expecting the baby to be born. The risk for House life is even higher than any regular omega.
House was thinking about the possibility of giving birth of their pup on their nest. That... was not recommended for someone with House' condition. Foreman, Cuddy, and the Diagnostic fellows accomodating of House making a new nest in one of a room in the ward. Based on how successful the later delivery, it would be then the calculations of when House could be back to his nest in their house.
It took them three weeks to finally getting House done from the treatments and operations or surgeries of the complications on his health after the delivery.
Wilson hands always in House' as he's laying on the hospital bed. House sometimes suddenly squeezed Wilson's hand, showing the uncomfort or the pain he felt; it happens while he's awake or even when he's sleeping.
The HR granting them the paternity leave for 6 months after House was giving birth of their baby (while on the last 2 months, they could give any formal consultation for the PPTH fellows or patients on-line). Considering everything, the baby is having a babysitter when needed, a trusted person. They would taking turns on who would the baby with. Mostly, the baby was with House.
House and their pup would spent their day mostly in Wilson's office when there's nothing House would do, considering Wilson would meeting his patient in an office in oncology ward. Sometimes, Wilson or House would just bring their baby to their Clinic hours.
They're incredibly protective of their pup, but people around them is joyous on having the baby to their care in turns; and both Wilson and House are relieved.
