Dressing/undressing ritual
Turn the act of getting undressed or dressed into a slow ritual. For example, at the start the dominant partner might slowly remove the submissive’s clothes as a way of “claiming” them, folding each piece neatly – or vice versa, the sub undresses the dom like an attendant. You could incorporate accessories symbolically (putting a collar, necklace or special bracelet on your partner to signify roles, then removing at end).
