Amazing sex and then nothing? [M]e (24y) & [F]Angel (21y) looooong story. My excuses for this.

STORY:
This is my first post here and my story started around the end of May and beginning of June. I’m “still” a student and only going to my third year of my bachelor’s degree now. What can I say? I’m not the best student in the world. But this girl isn’t either. Anyway.
Around the end of May and the beginning of June we have our finals here in my country. As I almost shouldn’t explain, students are mostly horny and specifically around that time of the year (or finals) even more. While tindering I found this girl (or did she found me? She swiped me right first I remember) I wouldn’t say she’s the most beautiful, but she wasn’t ugly either. If she would have a score, it’d be a very solid 7~7,5/10. On her profile she didn’t let anything really loose I would say? Just selfies of her face and that’s it. Let’s call her Angel (obviously not her real name), after the pornstar Angel Wicky, because this girl has some similarities with her. Both pretty beautiful small blue eyed blondes with some amazingly nice big boobs and an almost equall sex drive (which I both found out later during our conversations). For comparison I’m a white male, around 1,87m (6ft1) and not really in a super awesome shape or form. I do go to the gym but just for the fact so I can keep on eating my regular diet without really gaining or losing a massive amount of weight.
Angel is around 1,60m (5ft2) has a pair of the best D-cup boobs (god I love those) I’ve ever seen, her ass is lesser in size, but all things considered still in proportion with her boobs and a very pretty face even without make-up.
