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!

Do one oil change myself and it’s more than paid for.
Color: Silver, Color: Silver
It is 74 mm. It’s nicely made of cast aluminum. It has a rough cast finish so it shouldn’t be difficult to hold on to. It does fit my Lexus filter and the price is very reasonable. It also fits the oil filter on my 1999 (antique) Harley Davidson Heritage Classic. Which is the primary reason I ordered it. I don’t know this for certain but I suspect it will fit all HD EVO engines. That would be 1984 through 1998 except the Heritage which didn’t change to the 88 Twin Cam until 2000.
