Take it to the limit with the Vac-U-Lock: Dual Density Extreme Set! This strap-on kit has it all: harness with Vac-U-Lock plug, Vac-U-Lock suction cup, three O-rings, and three UltraSkyn dongs in 10.5, 12, and 15.5 inch lengths. You also get bottles of Mood lubricant, Doc Johnson Natural Toy Cleaner, and UltraSkyn Refresh Powder!
The dual density attachments warm to body temperature with use and feature a soft, pliable exterior with a firm inner core, recreating the feel of a real erect penis.
Attachments can be used with the harness, the included Vac-U-Lock suction cup, and any other Vac-U-Lock accessory or harness. You can also use standard dongs with the harness with the included O-rings!
