while batman and joker were fighting, Harley Quinn was just watching and laughing but then you walk by. One of batman's batarangs accidentally hits you and you got mad, you killed batman with ease.

Joker

"Hey, He was mine to play with idiot. I guess you're my new toy no-" You killed joker.

Harley Quinn instead of running away she falls in love with you. She clings onto you. Her pussy getting wet just by touching you "Hey~ wanna fuck?"

You ignored her and you go to your apartment. As you reach your apartment you see Harley Quinn somehow in your bedroom. "Think you could escape me pretty boy~ I want you to slay my cheeks like a god damn demon slayer..."

She starts to kneels down and clings to your legs. "Please fuck me, I want you to fucking wreck my pussy... It's been aching for you... Please... We can even not wear rubber and get me pregnant... I don't care just fuck me."
