Windy Jackhammer

The act of receiving a blow job while your partner is laying upside down on a couch (with feet in the air) . . . with the receiver leaning over the giver ....in this position the giver is staring at the gouch (hairy region of the body between your asshole and ball sack) of the receiver . . thus the jackhammer (your monster cock) comes in when the giver is pounding the back of the receivers throat....while pounding away the giver farts on the face of the receiver.

i was wearing high heels while receiving a windy jackhammer and thats when he accidentally shit on my face instead of just farting.
