If you have never tied anybody

6 positions that need nothing you have to buy, one from each shape.

Arms held in a cross Arms held straight out in a cross. Nothing looks easier and nothing gets heavier faster — a good demonstration that you do not need equipment to make somebody suffer. EasyNothing to buyWorks alone
Bondage-tape arm wrap Bondage tape wrapped along the arms. It sticks only to itself, so it never pulls hair or skin, and it is the cheapest way to find out whether being wrapped does anything for you. EasyNot past 15 minWorks alone
Seated and secure Wrists to the arms and ankles to the legs of an ordinary chair. Sitting is comfortable for a long time, so this is the position for interrogation, teasing and anything slow. EasyNot past 25 min
Folded and held Folded at the waist with the wrists bound. The plainest presented position — the ass is up, the head is down, and the strain in the back is what ends it. MediumNot past 12 min
Hobbled with a belt It takes the stride rather than the limbs, so somebody can still walk, kneel, fetch and serve — a whole evening of ordinary tasks made visibly difficult, with one belt. EasyNot past 20 minNothing to buy
Face down, spread to the corners Face down, spread to the corners. The back, the ass and the soles are open, and being unable to see what is coming does half the work. MediumNot past 20 min
