Great photos! She is definitely a winner! Such a sexy girl. Are you certain she is taking those pics?? Some of those angles are tough to do by yourself... That would be hot too...
Since you are apart maybe you should get some fun photos from her at the end of every call / skype / whatever you use... After all, you need something to keep you going during those long lonely periods apart...
Denim minis are hot - as are any mini. And your GF has fabulous legs which need to be seen and enjoyed. Most minis give goood upskirt views - almost impossible not to. Maybe she really needs several additions to her wardrobe.
Always liked those flirty / floaty minis that the wind catches often revealing even more. Best when paired with sheer lace lingerie.
You are right - slow and steady is the best way to encourage changes which push on boundaries. And there may / will be set backs but a small break followed by new perseverence often pays off, over time. A pub with those high tables works as well - almost always a good show, and a beverage or 3 helps lubricate the process. Your Gf may be more comfortable expanding her horizons when visiting you as she is away from her home. Many / most women are less inhibited when away from people they may know.
