After presenting the busty babe with a wad of $50 notes, Martha swivels round and proceeds to twerk, wind and grind seductively on the couch in front of her gentleman friend.
The party-goer flicks note after note at a dancing Martha as she shakes her derriere cheekily for the camera.
The Bondi-based beauty professional wears a Gucci belt bag round her petite waist.
The clip was recorded months before Martha joined the cast of MAFS.
The saucy footage comes days after raunchy images were spotted on Martha’s Instagram, including one showing her locked in a passionate kiss with a pretty blonde in Bali.
Martha took the plunge of applying for the social experiment after six years of being single, which she openly attributes to her high standards, pickiness and obsession with control.
The raven haired beauty has been candid about her fear of being hurt by men, shutting herself off from potential relationships as a result.
