Think games you might play at a batchelorette party... or any party, but with a sex toys twist.
Name that toy
Place toys in a bag, seal the bag, then pass it around the group and have each person feel the items through the bags. Have the guests write down their guesses.
Then open the bags to see how many are correct. You might give the person with the most correct guesses one item. You could probably even hold each sex toy in the air (without the cover over it), and have a guessing contest as to the name and function of each toy.
Also, like men name penii (or so I'm told), maybe ladies could name vibrators or dildos - funny things, like, 'Scary Rabbit' for the pink one with rabbit ears.
A lot of people at these things are uncomfortable, so probably not truth or dare, or anything where people touch each other, certainly not anything outside the house. Be very conservative or you'll scare them away.
