IDK if that is the correct word.....but its a toy like a flesh light. It has the vigina lips but its not ribbed on the inside. Anyway i dont know if it was the new feeling or if it had a tighter grip then my hands (dont think so) or what, but it was the most powerful orgasim i have ever had.....My jizz shot out the other side like a rocket and I damn near passed out:smile::smile::smile::smile:I almost could not touch my dick for almost 10min after that because it was so sensative and i may have shot another load lol:biggrin1:
