So I'm a freshman at a big university right now, and I met this HB8 on the first night. Essentially I picked her up from a university concert with the opener 'you look bored' along with her hot asian friend. She was my target but I guess I spent too much time on her and I ended up dancing with her asian friend and f-closed her that night.
It had been a while since then and we'de partied together maybe 3 or 4 times. This past Thursday I went out with some friends and ran into her at a party. Her friend Sarah was throwing herself at me and I think this was a perfect DHV. I was hitting on everyone in sight and it seemed to work pretty well, she also saw me being led by the hand by a some girl I had met that night to the roof etc.
We ended up going to her friend's dorm to smoke some weed and eventually I decided I wanted to go smoke with my friends from my dorm. When I told her I was going to meet up with them she said she wanted to come with me (leaving her passed out friend). We smoked and I kino escalated slowly until she offered to get her hookah and smoke some more after my friends left. We got it from her room and camped out at a spot. After a minute or two when she took a drag I told her to shotgun it, and from there we started making out. It got hot and heavy really fast and I ended up pinning her against a wall with two hands on her bare ass and rubbing me off over my pants. I actually slipped a finger in for a little bit and she enjoyed it. She said more than once to me, 'I don't normally do this kind of thing' and shit like that. My response was 'I have that effect on people'.
However when I asked her if her roommate was home she said, "I don't do that kind of thing!" She when I laughed and said ok she added, "oooooohh you wanted a blowjob didn't you?" with an adorable smile and I told her, "how do you know what I want?" and continued to make out. This was as far as it got and I walked her back to her room and kissed her goodnight etc.
Today I text her saying, "let's smoke some time this week", thinking the suggestion of smoking would be enough to remind her of the other night. She said "yeah for sure

"
I know the only thing keeping her from the bedroom is pure fear of being a slut. Everything she did seemed to suggest that she needed a better excuse to come to my room with me. What's an innocuous way for me to get her back to my room so I can really escalate?
