You need: Four neckties, or more elaborate restraints available at sex-toy stores or online; a bed, preferably one with bedposts.
How to play: Ties his wrists and ankles to the bedposts.
Why: It can be incredibly erotic to have him completely powerless, to be the absolute center of the attention and to have no responsibility for or sway over what happens.
Variation: If you don’t have bedposts, you may be able to tie his wrists to some part of your headboard or tie them together over your head or behind your back. You can get extra-long ties and be tied to the legs of the bed.
