I just started college, and realized I have a nice 4 hour break on one of my days. So I decided to call a girl I banged from college and give her a weekly class on my cawkk. Im mid conversation on the phone and I see this slamming girl. Probably a 9, and instinctly move in. Plainly said I want you're number and im going to class. Gave the ordeal about a boyfriend. Gawdd im so present It doesn't phase me for shit. Persitent and got the number. I already had the number before I even approached.

Anyways. Some of the more seasoned guys could help. How should I go about this.
