Blindfold him and keep him guessing as to what you'll do next!
PUll this blindfold over his eyes and have your way with him. It works great with sensory play, as he won't be able to anticipate where you'll touch him or what with. When you introduce a new toy or partner, he'll just have to guess what you're sliding into him, or wrapping around his cock.
Taking his sense of sight opens up a whole world of possibilities.
