Master Series Inflatable Hollow Strap On by XR Brands

Some strap-ons ask you to commit to one size. This one lets you change your mind mid-scene. The Master Series Inflatable Hollow Strap On is a hollow, realistic dildo built to slide over an erect or resting penis, worn in a stretchy harness sized to fit most bodies, with an inflator bulb that grows the shaft's girth and length on command.

Start by fitting the harness, adjusting the elastic until it sits comfortably against your body. Slide in, soft, hard, or going without, and the hollow shaft takes over from there, its textured silicone surface adding realistic feel against skin. Once you are inside your partner, squeeze the bulb and feel the shaft firm up and swell, thickening and lengthening in real time as you control the pace of the change. Leave the bulb attached if you want it bumping along with every thrust, or pop it off beforehand if you would rather keep things streamlined. Either way, the sensation builds gradually, letting your partner adjust to more fullness exactly when they are ready for it.

In silicone over a flexible ABS core with a phthalate-free build, it is fully waterproof and comes with an elasticized, one-size-fits-most harness.
