we only wear them for reading etc but love to sometimes get all hot and sticky wearing them, its a sexy look with cum on them, his and hers.
My OH has a pair she uses for reading and work. Once recently she wore them for me during a bj and let me cum on them, which was a total turn-on. Now whenever she gets them out it makes me smile.
I wear glasses all the time and sometimes forget to take them off for sex, but my OH always removes mine, says specs are a big turn-off when it comes to sex.
I take my glasses off for sex. The only exception is if I'm getting head or expecting to finish over my wife - that way I can watch the fun.
As for her, I much prefer her to take her glasses off. Then I get to cum on her, rather than a prop.
