You of the best amateur cuck movies was a clip of a wife sitting on her husband's cock. She lies back on him and the bull enters her pussy at the same time. After a couple strokes the larger bull cock displaced her husband's cock and it falls out. The husband tries to put it back in but is unsuccessful as the bull picks up the tempo. Finally the husband's cocktail falls to the side and begins to shrink in size.......I think it would be best to have one guy on his back, have my wife riding him with his cock inside of her already and then I slowly push mine in as well doggy style the guy on his back would have to relatively stay motionless or1 of us would get pushed out
