The smooth double sphere and dual-waisted design allows for the Black Collection to slide in easily and then stay in place. Not only that, but you have the option of how deep you go. Stop at the first waist and feel the sensation focused around the opening or go to the second waist and feel those tingles and contractions deep inside.

With four sizes, the Black Collection takes you from the unassuming Small to the more than challenging XL and with two other sizes in between there should be a size for everyone.
