Created exclusively for the Kink by Doc Johnson Wet Works collection, this sleek black fitted sheet protects your mattress during your wettest and wildest liquid play. Sturdy elastic at each corner and a generous 13-inch pocket keep this sheet securely in place even on extra-thick mattresses, and the waterproof material is heat-sealed at every seam to make it 100% leak-proof-get as messy as you like, and just toss it in the washing machine when you're finished. Kink by Doc Johnson is an exciting collaboration with Kink.com to create a collection of high-quality authentic fetish items suitable for long-term practitioners and new initiates alike.
