Take anal play seriously with the Ass Vault Locking Ass Expander! Made out of durable, non-porous, stainless steel, this plug is compatible with all types of lubricants and will last for years to come! For those who are kinky and love anal bondage, this is a must have! Using the flat, circular key you can expand the metal petals of the plug for a more intense backdoor fill that locks the plug in place. Once the gold pin flat key is used to officially lock the device, the petals won't move and your rear end will be stuck in whatever position that plug is last put in. Make sure not to lose the keys so you can release your bottom from bondage! Enjoy premium quality materials that are temperature sensitive and have a substantial weight to them that can be felt as a satisfying, constant, downward pull on the rectum. The tapered tip helps make insertion easy and the slim neck and wide base keep it safely in place without worry of it being slipped further inside. The plug can easily be cleaned by boiling it in water and cleaning solution or using isopropyl alcohol. Clean it before and after each use.

With the plug in a contracted position, use plenty of lube and slip the tip into your backdoor. For a more pleasant sensation, run warm water over the metal to warm it up before insertion. 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! As you find the desired expansion, 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 for safety reasons! Enjoy playing with your partner or even serving them and begging them to let you free after being locked into anal bondage! What will you do to earn release?

Excellent down alternative insert
Size: Full/Queen, Style: All-Season
I purchased this down alternative for my Airbnb because we can easily wash it. I love that it is fluffy and warm and easy to put into the duvet. Price was great as well!!

Feels luxury, I approve
Size: King, Style: Warm
I have purchased high end comforters/duvet inserts and this one is somehow my favorite. It's so thick and fluffy. I was going to do the double duvet insert method to create an extra lush bed situation, but honestly it's not needed at all with this comforter! It poofs up wonderfully inside my duvet cover (king duvet, king insert) and it's like heaven. It's very cozy yet airy, and it moves well during the night and does not fee too heavy despite its weight. This thing is definitely on the warm end and probably won't be suitable for Florida summers, but depending on how you set the AC at night it could be fine! The comforter is weighty, it feels like quality, and has a soft fabric. I wouldn't use it without a duvet cover, that's more of an aesthetic choice but I like keeping it clean. The white is very white. Honestly, I will be getting another one simply because I'm so impressed. Definitely no need to drop $300+ dollars elsewhere.

ALL SEASON IS TOO WARM!
Size: King, Style: All-Season
I got the King, All Season, to squeeze into a Queen duvet for extra floof and it's sooo cozy. Highly recommend. I redacted 1 star though because although it says All Season, the amount of down in here feels like it's for winter. The first night I used it I woke up dripping in sweat. It's currently March, I live in Los Angeles area, hitting about 75° weather outside rn, but I sleep with AC full blast at night (usually hit about 64 when I wake up). I can't sleep with it, I'll need to buy the "cool" one, and hope that isn't tooo thin. Don't get me wrong, it's a great insert, but holy hell, it's too heckin' warm. I saw someone else mention it and wish I had honed in on their comment. I don't wanna return it as it was used, so I'm stuck with it now. *UPDATE* I am back because I also bought the "Cool" blanket as well after experiencing the heat of the all season and it too is also too hot for me. I've had a duvet before but I guess not filled to the capacity of these blankets. If you're a hot sleeper maybe look elsewhere?

Buy this instead of the ‘brand name’ one
Size: Twin, Style: Warm
Tl:DR: Buy it, it’s super cheap, better than the one I paid 2x the price for and soft as it can get, and it really is a ‘Winter comforter’. This review is going to sound like I got paid off for it but I actually didn’t. I bought another comforter prior to this one, paid close to double of this one and that the ‘on sale’ price, and it is trash compared to this Amazon basics one. Both claim to be thick warm comforters but I can literally stack two of the other brand and maybe they’d be almost as thick as the Amazon one. I only bought this one because the other ‘winter’ one I bought was so thin and flimsy I figured adding another ‘cheapie’ one might make me not freeze to death. As soon as I arrived I noticed that this Amazon one was WAY thicker, nicer looking, softer and warmer than the old one. Just to try it out I stacked both of them together to see if I wouldn't freeze to death like I was doing with the old ‘expensive’ one: five minutes in and I was sweating. That’s all it took, I immediately removed the duvet cover from the old one, switched it to the Amazon one and threw the old one somewhere where I couldn’t see the money I had wasted, and yes the Amazon was warmer and softer even WITHOUT the duvet cover. I’m probably going to get the light version for when fall hits and I don’t quite need the heavy one yet. Buy it you won’t regret it and hey it’s Amazon brand so if you don’t like it they’ll take care of you, but I HIGHLY doubt you won’t love this thing.

Great duvet insert
Size: King, Style: Light
Perfect duvet insert. I got a pretty expensive duvet to cover this and they worked great together. The fit was perfect and I didn’t feel like the duvet was smaller than its cover. This was a cheap option that keep us warm while not being too think. This product is also breathable and recommend if you live in a place that transitions from hot to cold often.
