1 Get a hotel room in a fairly big city centre hotel.
She dresses up. You go to the bar together. You sit at a table in the corner, watching her sitting at the bar, flirting with the bar staff and any man who comes up to order near her. If there is someone who likes her, he will probably offer to buy her a drink and ask if he can join her. She can take it as far as she wants, from flirting to maybe kissing or even more if she feels ready and comfortable with him.
2. She poses for a photographer. Either non-nude sexy boudoir/underwear or, if she wants, topless or nude as far as she wants to take it. You could watch.
3. Ask if she would ever consider playing strip poker with another couple.
We would be happy to help out with any of these. DM if you are interested.
