Double Dildo

What is a double Dildo? Double Dildos, or double dongs, exist in two main forms: 

1) "Double Ended Dildo" : Those dildos can be used simultaneously with your partner. For example, the Dillio Double Trouble is long enough that it can be used and shared simultaneously by you and by your partner.

2) "Double penetration dildo" : Those dildos are used by the same person and allow for a dual penetration. For example, the King Cock Double Penetrator is a suction cup harness compatible dildo that you can use for double penetration.
