Steve Rogers aka Captain America is not only an Alpha he's THE ALPHA of the Avengers. (Y/N) is a new recruit that just so happens to be an Omega. The day you meet Steve for the first time is, unfortunately, the same day you go into heat and it drives him up the wall backward. This story does in fact have a LOT of smut. Smutty McSmut Smut for DAYYYYSSSSSSSS

In a world where Alphas and Omegas don't truly emerge until they meet their mates for the first time...you began to wonder if you'd ever meet yours. Until Bucky Barnes walked into your life... Warnings: ABO dynamics, language, smut, angst

What started as keeping the centuries old creature of the night busy while your team took out his nest turned for the worse. You were captured by James 'Bucky' Barnes, an ancient, the only one left who was born the way he was, a creature Of The night that preyed on the living. You found yourself in his home surround by god knows how many of them. He has chosen you out of all the humans he has come across, but what he has chosen you for eludes you. Bucky Barnes AU
