You can't force anyone , it will backfire and never happen....... take your time, and play act for about 6 months when you have sex, tell her / ask her who she fucked this week??( no names, just how many & when)--- Play act and both of you talk dirty and fantize about it ......say you like fucking her after someone else did. Be patience and just play, if it takes a year, so be it, in the meantime have fantasy fun..... eventually she will get curious enought to try,,, or she won't.
