This item is very basic. I would almost call it a "replacement part". As you can see it's a little red plug with snaps on it. It is designed to be used with this harness Ultra harness 2 'only' – panty harness, or one like it. It does NOT come with a harness or straps, what you see is what you get.


Here is the concept, you take the red little guy and push it through the hole in the harness and the snaps hold it in place. Then you take a little of this powder, Vac-u-lock powder lubricant (NOTE: The powder on the previous link is not intended to be a sexual lubricant) and dab a bit on the red plug and the toy you want to attach to it. The toys that are intended for this plug are usually soft and pliable, and they must have a hole in the bottom for the plug to insert into. Here is an example The original vac-u-lock dildo. It also works with other dildos that may not be "official" Vac-u-lock. I have a few dildos that have a hole in the bottom intended for an egg to be inserted, but this plug works great in them as well.


Now once the dildo is firmly attached to the plug, you wear the harness, and "do" your partner. This works for 2 girls, or a girl and a guy, any number of combinations run through my mind. The plug comes in a simple clear plastic bag with a nice four color brochure/manual that show a number of the attachments and accessories that work with the Vac-u lock system as well as very descriptive instructions, along with diagrams. All in all I would say this plug is pretty sturdy and would last a long time.


This is one small but important component in the Vac-u-lock family, and there are a BUNCH of attachments in the Vac-u-lock line. Doc Johnson Vac-u-lock
