Say hello to the new girl. Maybe something'll come from it

You keep your eyes a little longer on the new girls behind, noticing how her shorts are showing off a little bit of her lower buttcheeks like a tease.

Deciding that at worst she will show no interest, you go and try to talk with the new girl. Who knows maybe you get lucky?

"Hey, there you must be new, looking for a workout partner!" You greet the cute doe.

Looking at you in surprise, before smiling she answers "Oh yes, I would like that."

Well that went well but now what?
