There are many other things you can do.
1) Finger her (you've already done that obviously)
2) Ask her if she has any toys (vibrators and/or dildos). I'm sure she has a vibrator. Then ask her if you can use one her toys on her. I'm sure she will accept your offer.
3) Ask her about her fantasies (some fantasies don't have to be about vaginal sex)
Also, there are things you can do while making out with her that are very pleasurable.
1) Kiss her neck
2) Play with ear lobes with your teeth
3) Kiss her stomach
4) Suck on her fingers
I recommend just finding out what she likes and build up to sex rather than just doing sex from the start.
I will do my best to reply with an educated, humble and honest answer. Ultimately, it is up to you whether you want to listen to my advice or ignore it completely. Sometimes, my advice may be wrong; occasionally, it will be right. Regardless, I want to do my best to give people answers they are seeking.
