Sensry deprivation is something I like to use alot with just one of my subs,it is a form of punishment as she hates it, (though unfortunatly she's getting more tolerant as she's getting used too it) what I usualy do is to tie her to my four poster bed and insert a pre-timed dildo. (It's usualy set too bring her close to climax once every three minutes)

Once I've inserted that I place the hood on her my male sub watches her to make sure nothing bad happens and normaly she's left for about an hour,by which time she's normaly she a quivering ball aching for an orgasm.
I'll normaly use this form of punishment if she's cummed when I've told her not too or something similar.
