The sensation during an act of vaginal-anal double penetration when one man can feel the pressure from the other man's penis from across the vaginal/anal wall.

Pleasurable for the woman and both of the men.

Differing sensations can be achieved depending on the speed and force of the thrusts and whether or not a constant rhythm is achieved.
