The suction cup for HUNG System is strong and holds extremely well on smooth surfaces such as tiles, mirrors, doors and the side of your bed. Because you don’t have to hold the dildo/butt plug in place, you can give yourself or your partner the ride of a lifetime, completely hands-free. As the suction cup is sold separately, you will need at least one. The ribbed shape of the HUNG System’s attachment also ensures that any dildo or butt plug with a good size hole drilled into it can be used too for a hand free ride. Separate/spare suction cup attachment, designed to hold HUNG System dildos extremely well Very strong suction on smooth surfaces Give yourself or your partner the ride of a lifetime, completely hands-free Easy to remove for hygienic cleaning Suitable to use for both women and men.
