An erotic (to me at least) suggestion:

1. "Dangle" a lovely model, by her breasts only. Obviously not every model can take on this role.Use soft leather or or soft rope to encircle her tits, the slowlyy lift her by a pullly syste over a branch (if outdoors) or a rafter (if indoors).

2. As you lift her, have her dressed only in a pair of panties and a pair of moccasins, at least a full size too large for her feet....and held on her feet only by her toes.

3. If she kicks enough to lose a moccasin, the foot (or feet) now barefooted are caned....plus she is stripped of her panites and re-dangled....until she hangs by her tits for two minutes without losing a moccasin
