Prey Drive

Peter Parker, a resentful Omega, gets his dream come true when he is bitten by a radioactive spider. His Omega scent is dulled, he no longer gets heats, and Alphas no longer grope him all the time. Although he hid his secondary gender when he was Spider-Man, he still felt like he was helping the world see that secondary genders don't have to define you.

Then... he gets his first heat after the spider bite.

And he found that spiders- one of the only species in the Animal Kingdom that don't have Alpha, Beta, and Omega dynamics- and humans don't mix all too well.

Alphas have always been on top. They didn't have to worry about being afraid of walking to the store and being claimed. Then being treated like property for the rest of their lives.

Only now...
There was a predator to hunt the Alphas... and he was terrified by what that meant.

Also posted on AO3. It'll have more chapters, I'm just seeing how it'll do on Wattpad.
