so that girl was just here
we made out for about an hour and were beginning to fall asleep and then she suddenly says "I gotta go home."

She said she didn't want her to be a hassle in the morning. I was like ....alrighty.
should have started to kiss her neck, work your way down, then lift her shirt and kiss her tummy, and keep lifting until you can see her bra and look at her and see what her reaction is. If her eyes light up and she says go, go for it. If not, don't say a word, and slow bring her shirt down while still kissing her stomach and work your way up again.
who cares if you don't "like" her. You're a man. This is about conquest and seduction.
Are you a virgin or not? Making out by itself gets boring after a while, you should put some passion into it. It'll make her pussy fried.
Keep in mind next time you make out. Make her whole body your canvas, not just the lips. Shows you have courage.
