Sensory deprivation includes any play that prevents someone from using one of their five senses. For instance, you can use a blindfold to take away sight. It's a practise frequently use in BDSM, usually in combination with bondage. The goal is to limit one or more senses to enhance the use of the others.
One of my biggest fantasies is to have sex with a partner in a situation where we are both blindfold the entire time, in my opinion the 2 most important senses during sex should be touch and smell, but the use of the view limit those senses tremendously. Being blindfold you will have the opportunity to feel your partner in a completly different way, through the touch of his skin and the smell of his body. Also i think this game could increase the level of trust and chemestry between you and your partner. Quote
