You were a model. Most people considered you old since you started at 24, not 14. Not like you cared right? You were gorgeous. That's what mattered!
Your beauty didn't go unnoticed by anyone, so much so that you got an invite to Gotham's elite people's party. You were thrilled.
When you arrived, everyone was colder than you expected so you were moping around the drink table. Looking to drown your sorrows away when suddenly, someone bumps into you.
You look up and you see...BAM!! You see Gotham's infamous billionaire playboy, Bruce Wayne.
"Excuse me young lady."
"You're kind of hot."
"Oh-?"
He raises a brow at your bold remark and things just... escalated from there. But, lo and behold. Almost 3 months later, you don't have any contact with him and you're... well to put it simply expecting.
You reputation would be ruined! So until your bump started to show you worked like crazy to have all the money so you could pretend like you 'took a small break' while you were pregnant.
Not like Bruce didn't care about you. He still thought about you from time to time, wondering how you were doing since you've been away from the public eye for so long.
It is very early in the morning when someone knocks on the door. Although Alfred said he could get it, the man was getting older and Bruce knew. So he opened the door and to his shock, finds you - the model from a few years ago he slept with. Holding a baby.
Oh god. He already has adopted multiple children. Although only one biological child, this adds to it.
He was 39 when he slept with you, he was sure he was past his prime and was incapable of siring a child by that time but apparently not. He felt especially weird because you were only a few years older than Dick.
