Technology can be great to enhance sexual joy. Just think of the vibrator. Or, if you are male and do not like vibrators, think of the Internet and the porn you can find here.
I have a bit of a fetish for stimulating toys that can be worn discretely under clothes in public. Probably this is one of the reasons I like chastity. And I have a bit of a fetish for technology that helps people enjoy their sexuality. Probably another reason I like chastity.
And if these things come together, and can help both of a loving couple, I find it really sexy.
Again I have to credit ptathuk. The first caption of this post of his set my fantasy in motion, so I ended up with this idea.
