Wood switching
BDSM idea by Magnuz Binder.
Whenever your exhaustion and the short rope hobble between your ankles makes you sag behind, the harsh ropes through your crotch are tightened by the leash to them. The tight knots on the ropes are pushed harder and rubbed against your most sensitive spots: your clit, your vaginal opening, your sphincter and the tender spots between your vagina and anal, and just rear of your anal. The sensation makes you moan and whine behind the gag filling your mouth and forces you to a new effort to keep up with me.
Finally we reach our destination, and I push you to face the trunk of a pine, tying you to it by a few strands of rope circling your waist and the trunk. I throw the leash to your crotch ropes over a branch and pull it tight, forcing you up on your toes to relieve the pressure in your pussy, before tying the leash off. Your arms are kept well out of the way, tied high up your back, disabling you from doing much but wiggling your fingers. As you tether to remain your balance, you rub your breasts and stiff nipples against the trunk and force the crotch ropes to rub your pussy.
I cut a switch from a nearby bush, stripping it of leaves and minor twigs, and pull a small but strong vibrator from my pocket. I push the vibrator onto the knot pressing into your clit and starts whipping your ass with the switch. Your screams behind the gag soon turns into moans, and your thrashing soon turns into sensuous writhing, as the suffering gives way to arousal and the pain to pleasure. You cum, bucking wildly against the trunk, but I keep the switch and the vibrator going, building you up and tipping you over, again and again, deaf to your pleas for release and relief.
