The head of the penis is home to a whole lot of nerve endings that feel incredible when stimulated and penis head pumps target that exact area. This type of pump generally has a nice tight inner sleeve that clings to your penis while you pump , thus creating a sucking effect. There are also penis head pumps that are designed to pleasure you while you use them. Some have vibrations to tease the tip of your cock and some will even have tight rings that sit over the sleeve and stimulate your penis as you pump by creating a stroking sensation.
