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!

Great buy
Color: Blue+Red
My dogs kill every toy. They arrived very agressive chewers. These have lasted way longer than most balls have. Great value

If your dog loves tennis balls, you NEED these
Color: Azure+Orange, Color: Azure+Orange
Raising any puppy is tough. Raising a German Shepherd puppy has often left me questioning my life choices. So I was ecstatic the day that my 60-lb puppy decided that he loves tennis balls and occupied himself for 2 hours without needing constant intervention. Naturally, my immediate response was to make sure we had a constant supply of large tennis balls for dogs available. Now my puppy loves mischief, but he’s not an aggressive chewer. And I was irritated to discover that every brand and size of tennis ball broke within an hour max of play. By simply playing fetch and batting the ball around with his paws, every single tennis ball split into 2 halves. We needed something better! These squeaky balls are exactly that! They come in a 2-pack. I gave my pup the 1st one a week ago and it’s still going strong! We play fetch in the backyard, he brings it into the doggy pool with him, it rolls around in the dirt and can be rinsed off easily. It’s by far his favorite toy, and he takes it everywhere with him. Finally a squeaky ball that can keep up with my dog! These are the perfect size, texture, bounce, squeak, everything. These are the ONLY squeaky balls I will buy from now on. Five stars for sure!

Really are indestructible. Amazing product.
Color: Blue+Red
Wow! Really indestructible. Our large dogs have destroyed other “indestructible” toys in less than an hour and these are amazing. They squeak, which our dogs love (we hate) and they float when they go into our pool. IF they ever do wear out or are lost I will definitely buy again.

Durable squeaky ball for chewers
Color: Blue+Red, Color: Blue+Red
These are great! My 54 lb GSP loves them and it’s the only thing she cannot destroy! She’s currently 1 year and we have had the balls for several months. We have this brand and similar ones too. They float, bounce, and squeak. The ridges are good for chewing.

Finally a Toy My Pitbull Hasn’t Destroyed in 5 Minutes
Color: Blue+Red, Color: Blue+Red
I have a 65 lb pitbull who destroys most toys almost immediately, so I’m always skeptical when products claim to be “indestructible.” Most toys last maybe a few minutes in my house before pieces are everywhere. These have actually held up surprisingly well. The material feels durable and thick enough to handle really aggressive chewing, and so far my dog hasn’t been able to destroy them like he does with most other balls and squeaky toys. That alone makes these worth it to me. I also really like the size. They’re large enough that I don’t have to constantly worry about him accidentally swallowing them or choking while playing, which is a huge plus for bigger dogs. The squeaker inside also keeps him interested longer since he usually gets bored quickly with toys that don’t make noise or bounce around well. If you have a strong chewer or larger dog and you’re tired of replacing destroyed toys constantly, these are definitely worth trying.
