Hours and weeks of adult fun!
A couple reads the We've Never cards to each other and celebrates what they have done together. If they have not done the sexual activity on a card, but decide that they would want to in the future, they save the card and toast the adventure.
Play with your favourite beverages and toast what you have done and what you will do, or simply build up a collection of new sexual encounters for future use. The cards collected in your "...but we will" envelope are then carried out over the next few weeks.
