Not Quite Christmas by Aiden Bates

It was a mistake, a hot mistake, but still a mistake. One that should never have happened in the first place, especially with the boss’ son.
Lucas Shaw isn’t like the omegas he grew up with, in fact, finding an alpha and starting a family is the last thing on his mind. What he does need is for his boss to realize that he’s the perfect candidate for the Junior Architect position that’s just come up. The only problem? Brandon Grant, the boss’ son, just can’t take a hint. It was a one-time thing, a mistake, and one he’d rather not repeat. Ever.
His father’s assistant, an omega with a smart mouth and a quick temper. Perfect.
He’s been handed everything since the day he was born, but Brandon Grant is tired of being a playboy. He’s worked hard to build up his portfolio, but he knows that his father would give him any job he asked for… but it’s not the same as winning it on his own merit. Plus, working at Thompson Design would mean that a certain omega wouldn’t be able to avoid him for much longer. Lucas might think it was a mistake, but Brandon knows they were meant for each other.
