Your perfect strap-on experience is on lock with Doc Johnson's deluxe line of full-service Vac-U-Lock Harness Sets. The Vac-U-Lock Dual Density Starter Set provides a fun and innovative introduction to strap-on sex with a complete harness with removable o-rings and plug, three moderately-sized ULTRASKYN attachments and a bottle of Mood water-based lube. These dual density attachments warm to body temperature with use and feature a soft, pliable exterior that gives way to a firm inner core, recreating the feel of a real erect penis. Begin your exploration with the pleasing ridges and plush balls of the 5.5 inch textured cock, or go a bit deeper with the 6 inch spiral dong. For the strongest and most lifelike sensation, choose the 7 inch thin dong's realistic proportions, contours, and vein details. Attachments can be used with the harness, the included Vac-U-Lock suction cup, and any other accessory or harness in the line. The Vac-U-Lock Dual Density Starter Set also includes Doc Johnson® Natural Toy Cleaner and ULTRASKYN Refresh Powder to properly and hygienically maintain your dual density ULTRASKYN attachments. Every product in the patented Vac-U-Lock system is designed to help you create any strap-on or toy you're in the mood for, and it's as simple as popping on the attachment of your choice.
