Pump your cock or your nipples with a deluxe metal pump.
This kit couples our highest quality metal penis pump with a medium cock cylinder, a buddy connector, and two nipple cylinders. All of the cylinders come with vacuum-lock technology, so you can remove the hose and they'll still hold pressure. You can pump up your nipples, uncouple the nipple cylinders, and start pumping your cock; without releasing pressure on your nipples.
If you buy an extra cylinder, you can use the buddy connector to allow you and a friend to pump your cocks together.
