Bröstpump med ventil.

This Dual Breast Enlarger will add a new dimension to your foreplay or masturbation with this exerciser.
It is operated by a suction pump that has a quick release valve so that you are in total control of how little or how much suction is applied.
You can enjoy the sensation of your nipples being sucked to a tingly firmness whilst also having your whole breasts engulfed by the pair of cups.
