I don't think it's omegaverse either cuz it's the uke's ability so the cat he saw and kept eye contact for 5+ seconds was definitely not male...it was probably a female cat that's in heat so that may be why he said that. Though since 5 seconds have multiple stories, not sure if other stories got omegaverse. We'll just have to wait and see~
It's definitely not an omegavers.
True~ I don't think this is an omegaverse..'impregnate me' is heavily use in hard core yaoi after all (〜￣△￣)〜
first yaoi should be there for sure.
and lastly, I'm not entirely sure this is omegaverse. When an uke says 'impregnate me' doesn't necesarrily mean its an omegaverse （￣へ￣）
