First time having sex on the first date

So I never usually hook up on the first date but this time it actually happened. So this was back when I had a tinder and one day I came across this girl and she had an amazing rack like anime titties rack! So I’m scrolling through Instagram and I get a notification that I match with this girl! So I messaged her first about how good her music taste is and about her major. Turns out we both live in the same cities so eventually we agreed to hang out. When the day came I didn’t think twice about hooking up that day. It was more of an “Okay I’m going to hang out with this girl, take her out to eat, spend more time with her, and then call it a day.”
