Hmm... La Senza sells these really cute fluffy handcuffs.
I tried blindfolding my guy before and boy did he enjoy the 'sensations' of a full body massage with all my available body parts ^___^ I chose L'Occitaine's Lavender massage oil. Keep his underwear on when you do this till the very last minute. You can pull them lower or higher but no taking them off or exposing anything yet. Teasing is fun and easy without too much stress or effort. You can go slow so not to tire yourself out ^__^
Trust me when I say, "He will feel everything at 150% sensativity" ^__^
