Being Stubborn – Potrix

Tony is no stranger to people disliking him on sight, hating him with or without reason, but with Steve it’s different. There’s something about Steve, an invisible pull that draws Tony in, makes it impossible for Tony to take the easy way out.
He craves the confrontations with Steve, looks forward to them with an almost perverse glee, his head heavy and foggy with want. Tony wants, he needs. Wants it from Steve, needs it from Steve.
Whatever it is. Tony isn’t sure yet, but he’s determined to find out, no matter what. No backing down.

Omega!Tony wants adventure and excitement in his life but he’ll never find it under his Uncle’s guardianship. Anxious to escape a stifling life and a growing list of Alpha suitors, Tony answers a Lonely Heart newspaper ad and runs away to the Wild West.
Out in Wolf Canyon, Alpha!Stucky is facing discrimination, trouble and outright hatred for being an Alpha/Alpha couple and it affects their business and home as hatred boils over into violence and destruction. Desperation drives Alpha!Steve to look for an Omega that will understand the situation and be willing to platonic bond just long enough for Stucky to figure their way out from under Alexander Pierce’s thumb.
But then Stucky inadvertently imprints ‘mate’ on the Omega...and Tony starts falling for the rough Alphas and the platonic bond changes toward romance.
But the Wild West is an unpredictable place, and amid civil unrest, stampedes, storms and increasing animosity from Pierce, Stuckony finds themselves in more danger every day.
What’s a mail order-Omega to do when 'looking for adventure’ turns to 'falling in love’ and it’s more than just his heart on the line?

One moment they’re fighting, yelling scathing insults and ugly accusations at each other, and the next they’re kissing, all teeth and anger-fuelled desperation. Steve backs him up until Tony’s shoulders hit the closest wall, and hoists him up, giving Tony no choice but to wrap his legs around Steve’s waist for support. Tony bites Steve’s bottom lip, hard enough to draw blood, and Steve growls, and grips both of Tony’s wrists in one big hand, his hold bruisingly tight.

Tony had always expected that his awful kink would never be brought up to his alphas. It had ended more relationships than it had helped. But when Steve and Bucky find out about it, they’re… supportive? Tony has no idea what he did to deserve these two alphas that are willing to indulge his kink but he’s glad. Of course, they have a few kinks of their own that they’re willing to divulge now too.

Taking a shuddering breath, Tony shuts off the alarm, puts the phone away to stall for another moment or two, and then finally gets up, and reaches for what he has—very aptly, in his humble opinion—named The Stick of Destiny lying on the edge of the sink. He fumbles with it, almost drops it twice before he manages to turn it right side up, and sees the two bright pink lines that mean he’s royally screwed. And not in the fun way.
“Shit,” Tony croaks.

Tony, Bucky, and Steve are in a relationship, but neither Alpha feels comfortable doming their Omega, terrified of hurting Tony due to their strength or lack of control.
But because Omegas need to be taken down at least once a month to stay stable and healthy, they decide to entrust their Omega to the only other Alpha pair on the team; Clint and Natasha, who readily agree to help Tony.
If only Tony could get the courage up to actually go to them and ask for what he needs.
