Spread hogtie
From wipipedia.org
A spread hogtie is a variant of hogtie bondage.
Whereas in a hogtie the victim's wrists and ankles are usually tied together, in a spread hogtie they are fastened to the opposite ends of a spreader bar, or two such bars fixed together, behind the victim. The bar may be pulled up using head bondage, causing the legs to bend further. There may be a further bar fixed between the knees to reduce the mobility of the legs.
Another technique is to put the victim's legs in a lotus tie, then add a rope joining the wrists and ankles.
