A sexual act to which a man forcefully pushes his lubricated fist into the women's arsehole for her sexual pleasure. The man then brings out the fist before the women orgasms and licks the lady's rim whilst she shits onto his tounge. Better performed by ebony women due to their eating habits as they can push out more elaberat shits
