double penetration
A sexual position usually involving a female where, typically, two of her three major orifices (mouth, vagina, and anus) are being penetrated by penis, tentacles, clenched hand, dildo, other inanimate objects or a combination thereof. May occur together with the spitroast position and group sex; furthermore, this action could involve the rarer double vaginal or double anal. Also known as a "sandwich" and also abbreviated as "DP".
This can be seen at the same time as imminent double penetration if both the imminent penetration and actual penetration are depicted in the same image, typically a comic.
Could theoretically involve a male on the receiving end or two women penetrating another women, but such pictures are rarer.
Also see triple penetration.
