What are the logistics of converting a warm approach to a slay in the same day (as a 6'7 HTN) (extremely big tits)

Been talking to this hot chick with D cups in my class and she's been giving me iois. Every time we meet up she stretches her head all the way up and says "you're so tall omgg" I haven't gotten her phone number or insta yet but I'm planning to tomorrow and convert it to a meetup at her dorm and a slay (hopefully). Is it possible to slay her same-day as a non-chad? (Will make a follow up thread tomorrow with pics 100% and possibly slay footage if I'm successful)
