Had an omegaverse AU idea that feels like it might feel at home in your inbox, so here we go...
Hob is a pretty chill alpha who is happy with all kinds of partners. That's how he ends up in bed with an omega who asks him if Hob might be okay with a special kink of him. The guy likes to act like an alpha, and to make the fantasy complete, Hob acts like an omega. The thing is, while Hob just went along with it, he really really likes it. Oops, kink acquired. Hob doesn't mind, but it's a hard one to do by himself or one he can find a partner for, so Hob goes to a professional instead.
Dream is said to be awesome with roleplay and weird kinks and Hob learns firsthand that it's true. Being with Dream is so much better than it was with the other guy, after all, he really is an alpha and he certainly has a way of making Hob feel like an omega. Over time, Hob gets so into it that he's happy to act like Dream's perfect little slut and he loves when Dream acts like he's breeding him, whispering in his ear how well Hob takes him and how he's going to fill him up with his come.
They have a lot of fun until Hob has to cancel their meeting over getting sick. He felt a little weird for a while, but now he begins to worry over his weird symptoms and almost loses his shit when the doc begins a line of questioning about his sex life to the point of asking if he might be pregnant. Like, he's an alpha, that doctor is insane.
Hob leaves, but when Dream asks how he's doing, he has to admit that he still doesn't know what's going on. When Hob talks about his weird doc, Dream suggests another doctor and offers to come along. That's how they end up in front of Lucienne, who tells Hob that he is indeed pregnant. Turns out that while he has a dick, he also has all the necessary organs to actually have a baby. The only reason he got away with it so far is that he presented as alpha.
Lucienne is actually quite interested how Hob managed to present as omega all of a sudden, and when Hob admits to his "little kink", it all makes sense. Since Hob was so into it and Dream did such a good job with the roleplay, he accidentally bitched Hob so well that they didn't even notice the change, and since they kept fucking like bunnies, they made an oopsie.
Imagine Hob finding out that from one moment to the other he's a pregnant omega because he really loved Dream's dirty talk and getting knotted over and over again by such a nice and hot alpha. Meanwhile, Dream is losing his mind because they can't be serious. Yes, he totally loved the idea of Hob being his perfect little omega but it was just pretend. There's no way Hob would want a messy whore like him as his baby daddy. Right?
This is SO GOOD. Kink acquisition + accidental pregnancy is such an excellent concept.
I'm fascinated by the changes that would happen both in and outside Hob’s body. Now that he knows what's happening to him, he is more easily able to observe his symptoms. Of course the pregnancy kind of heightens everything, but there's also other stuff. A subtle shift in both his appearance and his scent. Wider hips, a difference in weight distribution around his body. People begin to treat him slightly differently, too. In public, alphas hold doors open for him and offer to carry heavy items for him. Instead of avoiding him, young omegas see him as a safe space and will ask him for help in public settings. Hob doesn't expect the euphoria that all of these small things provide, but he truly does find himself living more happily. Being a pregnant omega is maybe exactly what he's wanted to be for his whole life, even if he didn't know it.
The only trouble is Dream. Hob is convinced that Dream doesn't want to have anything to do with him or the baby. He obviously must just see Hob as a particularly weird client. He's been particularly standoffish, almost cold, and Hob is devastated but resigned to the idea that he'll be a single parent. He keeps Dream informed about the baby throughout his pregnancy though, just in case!
They're both very stupid, honestly. They could totally be together, preparing for a happy life with their baby, but both of them have so little self esteem! Neither can believe that they'd be wanted. Lucienne is banging her head on her desk after every doctor's appointment (Dream attends every one with Hob) because she can see that they're so compatible!!! They're basically true mates!!! Dream’s dick was so magic that it changed Hob’s secondary gender, of course they're destined to be together!!!!!
I fully believe that in the late stages of his pregnancy Hob would snap, though. He's SO pregnant and hormonal and overwhelmed. He's only been an omega for 5 minutes and the adjustment is so hard. His patience wears thin and he eventually begs Dream to just give him and their baby a chance. He NEEDS his alpha. He NEEDS Dream to step up.
And Dream, bless him, doesn't have to be asked twice. He does such a good job of stepping up that he sends Hob into early labour by knotting him so thoroughly. That dick truly is magic! Ultimately it all works out fine - their baby is perfect, despite their unexpected entrance to the world. Hob is exhausted and delighted as he feeds his child. Dream will need to look for a new job, but he's never been more content.
Hob really was the omega that the universe made just for him.
