Beginners Rainbow Locking Butt Plug

A Closer Look at the Rainbow Locking Butt PlugLove a locking butt plug but looking for something a bit more stylish? No worries: this plug functions like a regular locking butt plug, just with a rainbow color!

Easy to clean and easy to use, this plug is ready to beautify your—or your partner’s—anus while also keeping it captive at the same time.

Want to be free? You’ll need the key! Perfect for BDSM and power play, enjoy your next session with this stylish expanding plug!


  • Rainbow color
  • Locking design
  • Includes bag, lock, and keys


  • May be too small for some
  • Only offered in one size

My verdict

Like the last plug on our list, this locking butt plug is only offered in one size. While this—when combined with the expansion of the petals—should be enough to satisfy most users, size kings/queens may be left wishing for more.

Aside from the lack of sizing options, this plug is pretty good. We love the rainbow coloring, and surprisingly, you don’t have to pay a premium for it. This version is actually cheaper!

If you’re also a fan of the rainbow version (or you just want to save a bit of money and don’t really care about the pricing), we definitely recommend picking this pretty plug up today!

Set Anal Expansion Bundle

A Closer Look at the Anal Expansion BundleIt’s often said that variety is the spice of life. That may not be true in every situation, but it’s certainly true in this one!

This Anal Expansion Bundle contains quite a few different toys. From basic toys like a locking butt plug and an anal hook to an anal spreader, this kit has you covered.

For the less experienced, you can start with the basic plugs. For the semi-experienced, the expandable anal plug could provide a great challenge.

Regardless of your experience level, you’re sure to find something that you’ll love in this comprehensive kit!


  • Wide variety of toys
  • High-quality locking butt plug
  • Storage case included


  • Not all toys may be used
  • Expensive

My verdict

For customers who want a comprehensive anal play kit, this is definitely a good option. Offering a wide selection of toys, it’s appropriate for intermediate to advanced users. We probably wouldn’t suggest it for complete beginners, although they may be able to experiment with some of the smaller plugs.

Value-wise, it’s a great deal. The locking butt plug alone can go for up to $100! However, as a whole, the kit is rather expensive. This is another reason why we’d recommend it to people with a bit of experience under their belts. You don’t want to spend a lot of money, just to realize you’ll never use most of the toys!

We recommend taking a look at all of the different toys included in this kit. If you think it’s something you’d use, then give it a go!

Spreader Extreme Hollow Spreader

A Closer Look at the Extreme Hollow SpreaderIf you’re looking for a forced butt plug that doesn’t mess around, look no further than the Anal Extreme Hollow Spreader!

To be fair, this toy is less of a locking butt plug and more of a locking anal tunnel, but it works in a similar fashion.

Once placed inside the anus, this toy can be expanded up to 3.5” in diameter, giving you instant access to your partner’s anus for all the backdoor fun they can handle!


  • Simple wingnut design
  • Highly adjustable
  • Made of alloy
  • Can be used with enemas


  • Slow to adjust

My verdict

This toy looks intimidating, and for good reason: it can spread your anus to a whopping 3.5” in diameter! Our only real complaint is the design, which uses wingnut screws to manually adjust the spreader.

That said, this type of design is pretty standard among these toys, and this spreader only uses 3 (unlike other brands, which may use five or more). Although time-consuming, it’s definitely effective at offering accurate adjustments.

It certainly won’t appeal to everyone, but if it appeals to you, you’ll definitely have some fun with a partner using this extreme anal spreader!

Chain Tetine Butt Plug w/ Chain

A Closer Look at the Tetine Butt Plug w/ ChainUnlike the others on this list, this plug isn’t a locking butt plug: it’s a plug on a chain!

Small enough to be considered beginner-friendly but equipped with a chain, you can use this toy by itself or with a partner.

The chain opens up your options: attach it to your nipple clamps, use it as a leash, and generally just get creative with it!


  • Beginner-friendly
  • Weighs around 0.75 lbs.
  • Easy-to-use
  • Made of stainless steel & bronze


  • One size only
  • Expensive

My verdict

If you’d rather have a luxury plug than a locking butt plug, you can’t go wrong with the Tetine

Anal Plug & Chain. Costing over $150, this is definitely an item you’ll want to show off (although you probably shouldn’t).

That said, we’re not really sure why this plug costs so much. The addition of plated bronze is a nice touch, but it hardly justifies the price. Neither does the extra chain.

Overall, we’d really only recommend this plug to people who don’t mind dropping a lot of money on a premium plug. For everyone else, there are more budget-friendly options available.

Locking Chastity Butt Plug

A Closer Look at the Locking Chastity Butt PlugIf you’re looking for a locking butt plug that can’t be removed without the key, this lockable buttplug should do the job.

It might not be the fanciest thing around, but what it does, it does well.

Expanding inside their anus and secured with an included padlock, whomever this ends up inside of won’t be able to remove it until you use the key on this butt plug lock!


  • 350g of weight
  • Expands to 2 inches
  • Lock, keys, and bag included
  • Gender-inclusive


  • Expensive
  • One size offered

My verdict

Made of stainless steel, this item is crafted well and should offer years of exciting anal play. We especially appreciated that this locking butt plug comes with a padlock, two keys (in case you misplace one), and a bag for storage.

At face value, the toy looks quite intimidating. However, the 1.6” collapsed bulb—or even the 2” expanded bulb—may not be enough to satisfy all users. Unfortunately, this locking butt plug is only offered in one size.

Beyond that, the plug itself is great. The price is a bit high though, so we recommend shopping around or waiting until you can grab a deal on this high-quality metal locking butt plug!

Locking Chastity Cages With Butt Plugs

So far, we’ve taken a look at toys that can keep your anus under lock and key, but what about the other bits “down below?” Don’t worry, we have solutions for those parts too!

Deluxe Extreme Chastity Cage

Deluxe Extreme Chastity Cage

Combining a urethral plug, ball restraint, and butt plug into one item, the Deluxe Extreme Chastity Cage offers the easiest—and most entertaining way—to keep your man’s manhood locked away.

Female Chastity Belt

Ass-Gasm Cock Blocker

Ass-Gasm Cock Blocker

Perfect for long-term wear, the Ass-gasm Cock Blocker might allow the user to pee, but he won’t be able to do much else. Between the adjustable cock lock up front and the Ass-gasm serving as a constant reminder from behind, he simply won’t be able to get that “sweet release” until you let him!

Locking Butt Plug Safety

While using locking butt plugs can be fun and exciting, there are a few safety concerns that you must keep in mind when using them. Remember that all basic anal tips apply. Use lube, relax, and don’t rush: it’s not a race!

Don’t lose the key!

The main point is very obvious: don’t lose the key! Fortunately, most locking butt plugs come with two keys. However, if you can’t find either then you’ll be taking an uncomfortable trip to the ER.

Discuss Boundaries

Consent is extremely important. You and your partner need to discuss ideas and establish clear boundaries before using a locking butt plug. Although you may never need to use it, you should still establish a safe word. This will allow you to let your partner know that you need to be unlocked discreetly.

Find a keyholder you can trust

The whole purpose of a locking butt plug is that you can’t remove it yourself. However, the person who holds the key (the “keyholder”) essentially stands between you and an unobstructed rectum. For obvious reasons, you will only want to entrust the key to someone who you have complete faith in. Consider every potential keyholder very carefully before entrusting them with this task!

Use lots of lube

Lubrication is essential to any play. You can never use too much lube: worse comes to worse, you’ll just have trouble securing the plug! However, using too little lube can lead to discomfort, tears, and infections. Always be liberal when it comes to lubrication!

Start small

Wearing your plug for too long can cause issues, such as discomfort, irritation, or tearing. You should start wearing your locked butt plug for shorter periods of time before working towards longer time frames.

How to Use a Locking Butt Plug

They might be a bit more complicated than regular butt plugs, but overall, these locking plugs are still fairly simple to use. Here’s how.

Lube & Relax

After making sure you have the key on hand,  begin to apply lube to both your anus and the butt plug. Relax before attempting to insert the toy.

Insert the Plug

Once you’re ready, insert the plug into your anus. You’ll feel it “pop” in all the way once you reach the end.

Lock It

Now, the fun part. Using the key, lock the plug in place. You’ll feel the plug begin to expand during this time. Once the plug has expanded all the way and it’s completely locked, store the key away safely for later and enjoy!

How to Clean a Locking Butt Plug

Cleaning a locking butt plug is just like cleaning a regular butt plug: you’ll only need antibacterial soap (or toy cleaner) and warm water! Clean the toy once with the soap, then wash it again using only water. Alternatively, you can place your toy in a pot of boiling water for a minimum of five minutes to sterilize it (if it’s made of either silicone or metal). Avoid doing this to toys containing electrical parts.
Once your toy has been washed and/or sterilized, pat the toy dry using a hand towel and then leave it out to air dry. Never store your locking butt plug before it’s completely dried, as this may result in bacterial buildup.

Soft plastic, hard plastic, jelly, rubber, Cyberskin are all porous materials, meaning that small particles and bacteria can penetrate the surface. This makes it impossible to completely clean these types of materials.

Therefore, it is recommended that you use a condom with these types of toys, especially if you are sharing them. Clean these toys with mild soapy water and dry gently with a towel. These materials are more easily damaged, so be sure to be gentle and make sure your toys are completely dry before storing.

Silicone, glass, stainless steel and some hard plastics can all be washed using a mild soap (like you would use on your body) and warm water. Just be careful if your toy contains electrical parts.

Silicone and stainless steel toys without any electrical parts can also be boiled for sterilisation.

The toys with electrical
If your toys contain electrical components, be extra careful when cleaning them and always check the instructions provided with the toy. You can use a gentle cloth and soap to wipe or sex toy cleaner or cleaning wipe to down your toy, making sure that no water comes into contact with the electrical parts.
