This is a word association game so you don't need any props at all, just a very dirty mind and an extensive sexual vocabulary.
Sit in a circle. Starting with A, each girl has to think of a word to do with sex beginning with the next letter of the alphabet (A: Arousal, B: Breasts, C: Crotchless knickers.....and so on).
If anyone falters they have do a forfeit. These could be:
- Describe your first sexual experience
- Put a condom on a banana
- Fake an orgasm
- Do a sexy dance and be awarded for the performance
- Rank past lovers by sexual performance
- Describe your best sexual manoeuvre.
