Tie and tease is the practice of tying up a partner and bringing them to the brink of climax by stopping short and denying them an orgasm. In tie and tease, the bound partner is often stimulated repeatedly and held in a highly-aroused state without relief.
If the passive (bound) partner is permitted to orgasm, it may be more intense than usual due to the extended stimulation and resulting build up of tension and arousal. Alternately, the bound partner may be completely denied orgasm and left in a state of sexual frustration.
