Okay, you are going to have to excuse me for calling this post Katatsumuri Shibari 蝸牛縛り - the name to me sounds..rather fancy, but the translate 'snail tie' just doesnt sound like something you want to be doing in the bedroom!
This is a really simple tie, which results in a super hot position. The challenge is not with the tying, but smoothly getting your partner into the right position.
When tying the arms together remember that we are aiming for the area above the wrists, not the actual wrists which are partially sensitive to nerve damage. Tie either a single or double column tie around the arms tightly enough that it wont slip down to the wrist when you bring the arms between the legs.
