So there's this girl Erica in on of my classes at school. We were good friends last year, and this year we finally hooked up. The first time happened around Christmas. This past friday night i took her out to dinner and then we came back to my place to watch a movie and hang out (her suggestion after we left dinner). Get to my house and put on a movie. I knew she was expecting me to make a move during the movie, so i just didn't. I held her hand or whatever, but made no attempt to kiss her. The movie ended and she actually turned it off and got on top of me and started making out with me. I didn't want to directly try to finger her because i knew she would give me LMR, she was just waiting to slap my hand away. I read online something about indirect kino and i kind of used my forearm to stimulate her over the pants. It was working pretty good and she was getting more into hooking up. She was on her back and i was rubbing her inner thigh, attempting to arouse her even more. When i was caressing her inner thigh, she goes "It's not happening tonight" with a smirk on her face. I said "What are you talking about?" She crossed her legs and smiled at me and then we just continued to kiss. This girl is known to be a little easy, so I am kind of confused. Possibly she doesn't want to seem easy to me because she likes me? She knows i know her past, so she could be trying to give me a different idea of her in my head, who knows. But I need help. How do i get her stimulated next time to the point where she basically just wants to go further than kissing?? Also, how do i approach this from here on out? Do i ask her out again next weekend? the following? Please help! This girl is very cute and if i play my cards right i know i can slam it home.

I would say that she's on her period man, so dont worry about it now.
Yes, do something similar to what you guys did the past week and try again.
Try not no wait until the end of the night to make a move, it just builds up pressure.

What do you mean pressure? When do you suggest making a move?

If you start doing your stuff during the movie and she's like "it ain't happening" then just go back to the movie and try again later during the movie. Don't let it escalate to the level she wants then keep it going at that level because she is getting what she wants but you ain't so stop and go back to the movie, she should come around after you stop. If you doin it right she should be enjoying herself the second time and not want it to stop again so she should do what you want.
