    This anal queen is thrilled!

    Posted by Unknown on Apr 6th 2020

    Wow what fun. These are very pleasurable to insert and remove (I would say I’m intermediate level when it comes to anal play, for reference). Try twisting them around inside too—the colorful details are ridged and feel amazing. I used Sliquid Sassy water-based lube. Then they fit so snugly right against you, it’s quite comfortable. I just took them for a few laps around the house, and it was delicious. Can’t wait until coronavirus quarantine is over and I can go for nice long walks again... P.S. I am a women’s dress size US 18-20, and it is possible that those with smaller bums might find the T-bar too large or protruding. I thought it was perfect.

    Excellent plug, but the shape isn't perfect

    Posted by Unknown on Apr 26th 2019

    I like this plug mainly because of the stimulation of the ball jiggling around inside. However the abs sides are not a good shape for something that goes in your butt. They stick out more than the profile of the silicone and have sharp corners and grooves that can trap... things... It was also a little long.

    Double the fun

    Posted by Unknown on Apr 25th 2019

    The Duo is double the fun of the Uno. It like Ben Wa balls for your butt. The sensation of the balls moving around is amazing. They aren't as flexible as other plugs but are still comfortable to wear. I wonder what it would feel like to go for a jog with this is. Maybe one day I'll try it.

    Kegels for your butt!

    Posted by Emma (Rochester, NY) on Mar 4th 2016

    The Fun Factory B Balls are made of ABS plastic and coated with a matte, draggy silicone. I originally bought the B Balls for my boyfriend as an anniversary present, but since silicone is fully sterilizable (it's a nonporous material) we can clean it off with some toy cleaner/ boil/ sanitize and share. They feel similar to Kegel balls, but they're for your butt. Some of the pleasure comes from the girth, but for me, a lot of the pleasure comes from the feeling of the weighted balls moving inside of you. The base fitting comfy and snugly between my butt cheeks didn't hurt matters, either! The small ball is 1.25" in diameter, and the larger bulb is 1.5" in diameter, making it the widest part of the toy. The weighted balls, along with the girth, make this something I would not recommend to beginners to anal play. I've been working on sizing up for a while, so these were tough at first, because they are freaking heavy- but with a little bit of Sliquid Sassy, they went in fine. They feel great as long as you are moving, because the balls move and jiggle inside of you when walking, jumping, etc., and this is where they shine. But, when you're stationary, the sensations really aren't there, and you begin to notice the weight in an uncomfortable way. All in all, it's a good plug to mix things up and I'll be using it time and time again.
