interesting vid, thanks! But i would suggest, to connect your cockheads or headless pits. The united rods will bring more stimualtion in the normal pulling, rubbing and massaging, indeed jerking as usually. Additionally the piercing or ring will effect an inner stimulation of the nerv-knots in the tail-pit!!! And nevr rub the tails dry! a good oil, or creme or salive only will stimulate your splitted taill .

Additionally i mostly tie a rope around the tail roots and this will bring a betetr stiffiness!!! and so more stiffy and taut your tails will be, so more sensitive nerves will come to the surface of your tail-skin, especially the head-skin!! and so greater your chance to reach the orgasm.

Btw: Indeed with backward-help by a ramming plug it will go nearby each time, haha!!
