Boners - automatic penis pump masturbator (transparent/black)

Why is the Boners automatic penis pump masturbator so good?

Thanks to the vacuum effect, the blood vessels in the penis expand and both the girth and length temporarily increase - this is what the Boners automatic pump helps you achieve at the touch of a single button. The transparent cylinder lets you watch the process as it happens. The flexible sleeve fits snugly around the penis, so the combination of vacuum and sleeve pressure provides stimulation similar to a masturbator - pumping is therefore not only for size enhancement, but an enjoyable experience in its own right. It is recommended for use with water-based lubricant. Ideal for beginners as well.

How to use

Apply water-based lubricant to the sleeve, then place the cylinder over the penis. Press the power button - the pump will automatically build up the vacuum. The flexible sleeve fits tightly around the penis, and the vacuum plus pressure together provide stimulation similar to a masturbator. Start with a low intensity and gradually increase the suction strength.

Things to bear in mind when using the Boners penis pump

• Do not pump for too long in one go: for beginners, 10-15 minutes is recommended so that the tissues can gradually adapt to the vacuum.
• Use only water-based lubricant: other types of lubricant may damage the sleeve.
• Clean before and after every use with warm water and soap or a sex toy cleaner.
