The act of fornicating with two lubricated bare feet while inserting just the head of the penis into the female's oral cavity. Typically the woman sits in an upright butterfly position with the feet a few inches from her oral cavity allowing for maximum blowjob potential. Flexibility in the hips is required.
Treva: That couch looks comfortable!
Kori: Don't sit there. Meghan gave Jason a foot fuck job there last weekend.
when you go to your local kroger's or handy andy and buy a big tub of manteca (lard) then get a girl back to your place and you both dip your feet in it. Then you put your erect, manteca-covered toe in her vagina until she oozes. Then she masturbates you with her goopy feet until you squirt your man chowder. It feels like heaven and if you do this once a week it will improve your outlook on life.
Devin: Hey sweety can you stop by handy andy on your way home and pick up some manteca?
Jason: Why are you cooking?
Devin: Nope. I wanna foot fuck.
Jason: That sounds great! Isn't life swell?
Devin: Yes! Yes it is!
