Sensory deprivation is rather hot, so adding it to voyeurism is even better.
Adding adequate lighting wouldn't be so unbelivable I would think if you expressed how much you love her body and want to see the details of it when you're having sex she wouldn't mind having the lights left on. The more detail you can see up close the better you can eat her pussy right?
I'm a totally shameless perv, I know; I just don't care.
Really do appreciate what you do here though
