Both the bosom suction cup and the intimate suction cup are manufactured according to the Fröhle patent and are therefore even approved for the medical field.
With different pumps, for example a scissor handle pump, a negative pressure can be created, which stimulates the blood flow under the suction cup and thus provides a higher pleasure.
The intimate suction cup is particularly popular here, as the labia, which are pumped up and well supplied with blood in this way, are considered particularly attractive by men and react extremely sensitively to touch.
