The Stoya sleeve offers a tight entry with lips that grip, and then expands to encompass your entire girth. Submerge the waterproof Fleshlight in warm water, and then wait until it holds the heat.
Remove from the water (or not) and enjoy the warm enclosure that extends as far as you need it to. The phthalate free components make for a comfortable and non-irritating sensual experience.
Clean up with either antibacterial adult toy soap, or use a gentle soap and warm water to keep your version of Stoya in good shape for the next round. Use a water based lubricant to keep you from experiencing any friction.
