Using the NS Novelties Firefly Prince Anal Training Kit is easy. First, pick your preferred plug based on your comfort level and the size you want to start with. Apply a generous amount of your favorite lubricant to the plug and the area. Gently insert the plug and take your time to adjust. Remember, relaxation is key for a comfortable experience. As you get used to one size, you can move on to the next larger plug in the kit. When you're done, clean the plugs with mild soap and warm water. Make sure to dry them thoroughly before storing. Keep them in a cool, dry place away from direct sunlight. Always check the plugs for any signs of damage before each use.
