Try to blindfold your partner and go for a walk together. This practice will help to make the relationship more trusting and to awaken the feelings that will be most appropriate once the play is over.
Scenario
Think about where you want to go for a walk. Start with a quiet park near the house where the partner can get used to deprivation and your commands. You can start the play as soon as you leave home or you can put a blindfold on your partner when you reach the walk location. Take his/her hand and start walking slowly. While the partner tries to relax, re-group and enjoy the brightness of sounds and smells, your job is to watch the road carefully and keep him/her safe.
When you both feel more secure, you can increase the complexity level of the play. Take a ride in the city transport, take a walk in the city center, have lunch in your favorite cafe. Guide the partner, talk to him/her.
When you get home, we can have an erotic continuation. You can undress your partner and give him/her an erotic massage, feed fruit, drive an ice cube over the body, caress for a long time, make a sensual fellatio/cunnilingus. Enjoy each other, the new sensations and trust that this play will most likely generate.
When you are done, share your emotions. Next time, try switching roles.
