Go for bigger breasts and make your dreams come true with a breast pump from the SAIZ collection! This breast pump has two transparent cups that are attached to a grip pump. Place the cups on your breasts and make sure the edges rest against your body. Then use the pump to create a vacuum in the cups. This increases the blood supply to your breasts and they will swell and become more sensitive. You can easily lift the vacuum again with the air release valve. Clean the cups after use with a toy cleaner or mild soap for hygienic use.
