NEW STORY! Check out my Starker/Oc (not Prism) omegaverse story!
Tony/Peter/OC omegaverse. It's a dangerous world for an unmated omega, so to look out for his best friend Peter takes her as his mate back when they were 17. She only had a beta's mark, but it would be enough to deter most. He's oblivious to his feelings toward her developing past the friendship level while he falls in love with the daring, sarcastic alpha Tony Stark.
The two mate each other in a moment of passion, and Peter soon finds himself living a bit of a double life as he tries to juggle two mates. Naturally, this is short-lived, and he is forced to move his omega into the penthouse with his alpha.
His alpha was unaware of her existence due to the fact that most people didn't take their omegas mark for their own safety. But the silver bite mark on her mating glad was DEFINITELY Peter's...so it seems Tony is going to have to learn how to share.
Unfortunately, he's never been very good at that.
And now, Peter is stuck in the Middle.
