About to take girl I've had a thing for home tonight...how do I close

Background: took this girl home to some dance last year. Failed miserably.

Now after a night of hanging out she just asked me to take her home. Any tips to finally k close. First timer here. I'm a senior in high school. She's a college freshman

Thanks guys

update: false alarm, she decided to go stay at her friends house after she convinced her. fml. here's to next time the first time...
