Edible Undies
One of the simplest and most original games to spice up your routine is using edible undies. You can find a multitude of different models in any sex shop, and generally, they are not too expensive, especially considering that these garments are for one-time use.
The variety of products we can find is wide: from candy bras or thongs to intimate garments with multiple flavors, including edible body paints (in case you prefer to draw your own underwear).
In this link, you can find some of these products and purchase them at a discount if you're registered in our forum.
