Darcey face
When ur hitting another guy from behind and you hold your mouth and nose shut whilst shoving a bike pump into your rectal cavity. When the air is inserted as it cannot leave your face holes it is pushed out the penis and into your partners behind. After this happens air exits your companion via every body hole causing a wind effect except from the inside out.
Yeah I was hitting this hot AF dude and I gave him darcey face. Best sex of my life!!
