I know it’s been awhile, but I did have a sliver of time to write about bubble baths. I had a few during my visits, in fact, a bubble bath party was the first time I’ve entered the world of Sheri’s Ranch. They had a specific room for those parties back in the day (It’s now the Voyeur Room}. I would do the bubble bath a few times with no sex involved, until I was comfortable to engage further.
Probably the best advice is if you want to have a bubble bath as part of your experience, it would probably be wise to suggest a bungalow, at the least. The lady will probably suggest it as well. The bathtubs in the bungalows are big enough to have fun in, before and after the party.
Hope this helps you out. Good Luck.
