We want you to be satisfied, in more ways than one. And, while you're at it, have some fun too. This vibrator is made out of a pink jelly "gummy" material that absorbs body heat and gets warmer as you use it. It feels like the real thing. The ribbed design rubs inside you as a real penis would. It satisfies while the thumb teases your sensitive area. Requires 2 AA batteries (not included).
