We get it, sometimes, making a decision is hard! Should we diversify our investments or stay safe, should we get the pasta or the pizza, should we stay or should we go? We can't help you out with those types of decisions (except the pizza thing…always get the pizza!), but we can tell you that with Fanny Hill's Inflatable Vibrating Butt Plug, you can be as undecided as you like- at least in terms of butt plug thickness!Thanks to a unique blow-up ready layer over a nice firm core, the Inflatable Vibrating Plug starts off (relatively) small and sleek, but can be pumped up to almost twice the thickness during play. To experiment with different sizes, make sure the pump hose is attached before inserting. Once the classic taper is in place, squeeze the ball valve to fill the space between the core and outer layer with air. It balloons up nice and plump, reaching max thickness after about 10 pumps. Start up vibration using a tethered remote. 7 modes of steady, pulsating and escalating sensation pulse and throb from the core at the touch of a button.In ultra hygienic and hypoallergenic silicone plus ABS plastic, the Inflatable Vibrating Butt Plug is body safe and conveniently low maintenance. Wash well before and after use with some warm soapy water, or use a good toy care fluid/foam. You will, of course, be using lots of lube with this toy, so be sure to choose a good quality water-based formula. Please don't be tempted to use a silicone lube- it could break down the material. On that note, it's best to keep this (and any silicone toy) away from other silicone products. Requires 2 AAA batteries (sold separately).* Measurements represent the Plug not yet inflated.
