- This vibrating butt plug from NMC is a strong, hands-free experience (aside from you controlling the vibrations). The soft silicone plug allows for easy cleaning and creates incredible vibrations you can control with ease. The powerful suction cup at the base lets you attach it to any smooth, flat surface such as a tile floor, shower or glass door. Once you have it in place, the Shove Up butt plug is controlled by an external corded control panel so you can alter the vibration speed without interruption! This exciting toy has 10 powerful vibration functions.
