well maybe blood link, it's not omegaverse just vampire thingy
Deliverance of the Counterattack kinda fits this, it's the only one I can think of :,D

Oh my bad mreg without omegaverse isnt so common
mpreg with a buff. larger or physically similar uke to the top. anything where he's not half the size of the top really. or mpreg that's NOT omegaverse. no heats, ruts, knots or anything like that just regular degular men getting knocked up.
