Using your hands to squeeze your partner's breasts, can be enjoyable. However, the Steel Circular Tower of Pain adds a new dimension by using stainless steel crossbars to effectively squeeze and compress the breasts for as long as you desire.
Simply place the breasts between the crossbars and use the screws to tighten the bars against the breasts. This leaves your hands free to squeeze and handle other places on the body, as you desire.
The steel band is adjustable in the back.
