yeah we going freaky

such a rare gem (unless it turns out he's an alpha too happy either way)

Do you know of any others?

Sutenaide My Hero - omega tops alpha
Drugless Sex + Drugless Sex 2 - these aren't technically omegaverse, its got its own rules, but it feels very similar to omega x alpha
Omega bite - omega x omega
Takatora-kun to Omegatachi - omega x omega, unfinished and more intense than anything else on this list (in my opinion)
