How do I earn time with this type of girl?

This girl been all teasing me, all on me and touching me. I've known her for a bit so at first i didn't fw it but i gave in, she's cute and all. Im so shit at flirting though, reason i tell jokes and all that but with this girl im actually enjoying time with her outside of anything sexual so when i told her right there i wanted to take it further she said i had to earn it cause she ain't easy. Which is A OKAY i dont mind putting in the work But i didn't know what that meant, like I'm mad confused. Half of that time we spent sure i bought her like our food and spent time with her normally and at the end she gave me a "freebie" for the effort but i honestly don't know how to step it up, feels like i have no romantic bone in my body. How do i proceed with this or something. Doesn't have to be like to sex but just to be a little more "serious"

Thanks for the answers i looked em over n thought for a bit on what the next move was. I waited for a min and hung out with her like normal till i made up time to really go serious like i would a normal dating thing

wasn't so cryptid as i thought, thanks fr
