I think the thrill is the waiting and knowing what is coming, I like the idea of shopping for the clothes at a mall and have her model them in the store. You can even have her leave the curtain open a little if the room has a curtain or find a reason to open the door and hand her something while changing, exposing her to the store. The bowling alley idea rocks but I would have her wear bikini panties not a thong but slightly sheer. As the night goes on get more and more of her exposed, maybe end the night at an amateur night at a strip club. Also let people take pics all night and don't cover her face. The chance of ever seeing the pics is slim but the thrill is not knowing who has seen them.
