Spitroast
From wipipedia.org

The spitroast (also referred to as roasting and wobbly H) is a sexual position where a woman is taken from behind (vaginally or anally) by one man at the same time as being mouth fucked (or giving oral sex) by another. The woman is normallly in the doggy position, hence the name from the visual presentation of her being like a roast spitted on two prongs.
The spitroast is sometimes seen as a degrading sexual position but many women love the feeling of power and ability to satisfy two men at the same time.
