The Size Matters Nipple Honkers can enlarge and stimulator your nipples. Engorgement and increased blood flow to the nipples increases sensitivity and pleasure. Simply place them over the nipples and squeeze the bulb. The nipple honkers will create a vacuum sensation when you release your grip. After you release them, they will stay in place and you may enjoy hands free stimulation! The special extra cavity design accommodates nipple piercings, as well.
