Great for nipple play
I started using these nipple cylinders about 6 months ago. They provide excellent suction and they remain firmly in place after the connector hose is removed. I bought the small cylinders to start. They did an excellent job making my nipples long and hard. My nipples grew gradually. I became addicted to having my nipples pumped to the point that all I could think about was pumping my nipples. They would get hard just thinking about being pumped. Now I pump my nipples at least 4 times a day and I love it.
