Stripper Etiquitte

My girlfriend is a bit curious about teh same sex. We went to a strip club and had a couple of lap dances where the girl touched and rubbed againdt us. It got us really hot and had a great time afterwards. I am interested in a private show at our place or a hotel. She is not interested in like a full service escort setup. Just a bit more closeness and touching (breast and ass, no genitalia) between the two girls. How far does this typically go in private shows? or is this something unreasonable to ask for?
