Strap-on
The Strap-on is a special dildo with harnesses worn by women to penetrate another woman or, during heterosexual play, for pegging. In Ancient Greece, strap on dildos were made of stone or padded leather and were attached to leather harnesses, with olive oil used as lubrication. The Kama Sutra has mention of strap ons, and they show up in countless 19th century paintings and historical records from China, France, and East Africa. Today we also have strap-free strap-on, where the harness is substituted by a bulb inserted into the vaginal canal, which provides a good grip to the toy.
