Ever since Alastor came to hell he was an Omega. He always kept it a seacret beacuse if the other overlords found out, they would force him into some... 'spicy' things beacuse here Alphas couldnt get pregnant to Omegas carried the children even if they were male. Alastor never wanted that so he kept that he was an Omega a seacret. But you found out somehow... you made a deal with him; if he submited and became your Omega, you would keep his seacret and take care of him and protect him. He made the deal with you... suprisingly you never forced him to make... kids. And he apreciated that. You pampered and babied him 24/7 and you never left his side. The other overlords just thought you were his bestfriend

It has been 9 months since Alastor submitted to you. He was your cuddle bug. He loved you, even tho he knew you owned him but you were gentle with him. You were very possesive and overprotective over him beacuse you still didnt cleam him compleatly since you two didnt have any children so any other Alpha could easly steal him
