Colossus is suitable for slipping on to a more generous sized penis. Outer: 7.00 inches long by 2.25 inches wide. Inner: 5.5 inches long by 1.375 inches wide. Made using Vixen's ultra supple platinum silicone, the hole for the testicles is comfortable, due to the material and ability to stretch. The strap around the testicles allows for strong stable stroking.
Quick guide for putting the Colossus on: roll the sleeve one third of the way down. Apply lubricant to the inside of the Colossus and your penis. Squeeze out the air. Place your penis into the opening and gradually release the pressure. Unroll the Colossus to the base. Pull the scrotum through the hole. Pull to one side and push through one testicle. Repeat with the other. Have fun! Only use water-based lubricants with the Colossus.
