This is an omegaverse where you are an Omega hiding your true nature and pretending to be an Alpha. But by chance, during your heat, you find yourself at work in an office where Cartman catches you. He was considered the weakest Alpha, but now he knows your secret, what will he do to you?

( P.S. I don't like violent things, so Eric is not in his usual image here. If you want a more violent version, write in the comments.)
