What is a rabbit vibrator?
A rabbit vibrator traditionally is a kind of dildo which has an element of clitoral stimulation in the form of vibrating bunny ears. More recently, there are other models of sex toy that also feature the bunny ear design. Such as cock rings and personal vibrators.
The vibrators were originally made to look like rabbits to bypass Japanese obscenity laws because manufacturers weren’t actually allowed to produce sex toys. Rabbit vibrators became universally popular in 1998, after being featured in a Sex and the City storyline.
