How can I get her to try it?
Don't pressure her. When she's fucking you on top, use your fingers to spread her lubrication from your cock and her pussy to her anus. Stroke her pussy with your cock going into it and also her anus. When she's really into it, almost about to cum, gently push your finger into her anus. It'll make her cum like gangbusters.
Keep repeating this whenever you have sex with her on top, and eventually, she'll realize how turned on she gets when she has things in her anus. No guarantees, but maybe then she'll be more receptive to the idea of anal sex.
Get her really, really drunk, then when she passes out, Go For It!
P.S. When she wake up the next morning with a sore ass, be sure to thank her and tell her how much she enjoyed it.
