Any advice about first time visit to Greece? Thinking about trying it wit ATF next time we meet.

I've found that a vibrator helps me take a longer trip than I otherwise would've. And for you lube up, just ease into it and go slowly. Number one rule. Ask her before picking up the pace! Everyone is different but I find that it helps if I'm prepared and being informed before the other person starts going wild is very helpful Hope that helps at all.

I honestly assume you already know whether she is open to this or not...so assuming that she is, go slow.  Discuss her boundaries and preferences.  I prefer not going back and forth (please do not ask me to detail that last statement)...other ladies do not care and may even like that. Consider opening up digitally, orally, and/or with plugs before making the plunge.  Guide slowly and let her adjust...yes, a vibrator can make the experience pop.  Lube, lube...coconut or almond oil.  Exploring is fun...enjoy!

Thanks for the advice
