The Vac-U-Lock tm Modular Sex System is a strap-on system that really performs. It is designed for use by Women and Men. The patented plug, made of high-impact ABS plastics, holds the system attachments firmly, without any chance of slippage. Optional Dong, Vibrator and PPA attachments fit the Ultra Harness 2 and provide the users with a variety of different sizes and textures.
You can purchase the Ultra Harness 2 with a plug and choose an attachment or buy a complete set, which includes one attachment Dong, Vibrator or PPA. Other attachments can be purchased and used with your Ultra Harness 2.
The variety and versatility of attachments is legendary: from thick to thin, long to short, whatever you want, Vac-U-Lock tm delivers.
