grape seed oil is the best(can also be used as lube), you can mix in a little jojoba oil if it's not viscous enough for you. Feed her some sh!t about how these are the greatest natural oils for the skin and the contain vitamin A and E etc.
Just take control and pretend like you are a master masseuse. Tell her you will go to get the oils from the bathroom and when you get back she should be on her stomach in just her panties (be confident and commanding).
Start at the top and work down to her lower back and top of her bum (this can take about 15-20mins), then start at the feet working up the legs and into the thighs. The whole time you should be looking for knots and making up sh!t like "
What I'm doing right here is reliving the compound stress tension build up in your lower back, allowing greater glut activation when you walk to prevent lower back pain(many chicks get this)" what ever sh!t you can think of. It's always good to talk about her gluts tho.
As you move up the thighs, you will eventually start lightly brushing her pu$$y (like it's almost accidental). Then you will go back down her legs. You can start telling her how soft and smooth her legs are (whatever compliments you can think of) then move back up to her pu$$y again, but instead start working on her bum. Then just start to take her undies off because you need to have access to her gluts (she may resist the first time you try this, if so, just go back to the legs untill she is horny enough to start again).
Once you have her panties off you can work up to her pu$$y then slowly slide your fingers in, IT'S ON!
The massage is over and you can proceed to kiss her, then fvck her.
good luck
EDIT: make sure you play some sensual music.
