Add this Master Series Ass Vault locking ass expander to your collection of extreme industrial anal toys! It responds to temperature, so you can heat or cool it for extra sensation play! With 3 expanding petals, you can widen the girth of the plug and stretch open the anus from within. Enjoy the added pressure from stretching the insides of the ass! While the petals are folded in, the plug is smooth, sleek, and easy to use. The curved, wide base helps with handling the plug and is a safety feature that keeps it from going past the sphincter. Use the key to expand or contract the petals and the locking key to hold it in place once you've reached the desired girth.

IMPORTANT:   The key to anal play is to take it slow! Attempting anal penetration before you are properly aroused can be unpleasant, so allow yourself to relax in order to enjoy the experience. Finger play is a great way to relax the anus. The anus and rectum DO NOT have an automatic lubricating system like the vagina, so use plenty of lotion to reduce friction and increase pleasure.
WARNING:   For safety reasons, DO NOT misplace or lose the gold pin and locking key or the flat circular expander key.

How to use

Start with the plug in a contracted position, petals closed. Run hot or cold water over the metal to add in some temperature play beforehand. A warm plug will help relax the sphincter while a cold one will be more surprising and cause some tension. Use plenty of lube and slip the tip into your hole. Once inside, use the circular flat key to expand the metal petals; only expand the petals to the degree that is comfortable and don't force it! Once you get the petals open to the degree you desire, use the gold pin locking key to keep it in place so it doesn't contract again until you let it. Make sure not to lose either key or you won't be able to remove the plug once expanded! If the plug is used on someone with female anatomy, pay attention to her vulva as you insert your fingers or hand inside of her vagina and massage. Feel for the pressure of the metal petals from the other side of the thin, vaginal wall and find ways to stimulate her from both sides! If you have someone with male anatomy, stroke their cock and give them head as they enjoy the pressure from the plug! Or, for either body type, make them do your bidding, serving you until you release them and fuck their ass!

Holds up pretty well.
Color: Green Helix, Size: Medium
Holds up against my velociraptor! Much better than some of the other holey balls that get torn apart quickly. I think this is a great idea to reuse old shoe soles into toys for the heavy chewers like heelers. I would like to see a large ball like 10-12 inch diameter, so they can push and throw it around.

Molly loves her ball!
Color: Blue Helix, Size: Large
Soft and easily caught by a rambunctious Border Collie. She loves her ball and points to it with her nose when she's ready for another game of "ball". Easy to throw and easy to clean of slobbers!

Great Strong Chew Toy but not too Hard
Color: Red Pulse, Size: Medium
Great strong chew toy. It's very strong and does not tear apart like everything else. At the same time it is not hard plastic like the last brown one I ordered that could break my dog's teeth. My dog is a 2 yr old 14 lb Chi mix with a super strong bite. He tore all the stuffies up and even the nylon toy that was supposed to withstand a lot. This is the one toy that could outsmart him. I play fetch with him and it has a nice weird hop due it's shape so it keeps him interested and surprised. It's a bit heavier than other similar toys and I'm guessing bigger dogs would definitely like it too. I'm very pleased after buying so many others that were easily chewed up or too hard.
