The spiral futomomo is a classic technique in Japanese-inspired bondage. It’s one of several techniques for tying a futomomo—see the ladder futomomo for a completely different approach.
This is a great tie for practicing basic tying techniques like controlling tension and using frictions. It’s also a great way to immobilize the legs. We love it for oral sex but find it awkward for penetration.
1Tie a column tie around the ankle.
We prefer a single wrap for this column tie.
2Make a spiral wrap around the thigh and calf.
3Make two more spiral wraps, ending up two thirds of the way up the leg.
Going closer to the knee makes the futomomo more effective but harder to tie.
4Make a final horizontal wrap around the leg, crossing itself at the crease between the thigh and calf.
5Make a Munter friction where the lines cross.
We’re headed straight down, so it doesn’t matter if you begin the Munter on the left or the right.
6Go straight down the leg, making two more Munters where you cross the spiral wraps.
It’s more comfortable and attractive to stay right over the crease between the thigh and calf.
7Make a 90° bend at the the bottom line and go between the thigh and calf to the inside of the leg.
Be sure not to leave any slack in the rope.
8Make another 90° bend at the bottom line and start going up the inside of the leg.
9Continue up the inside of the leg, tying a Munter at each subsequent wrap.
10Secure the final Munter with a half hitch.
