Wifey and me used to fuck everyday, except for the days in which some of us is traveling. This could be enough sex for the main part of women, but not for Wifey, so she has to masturbate sometimes.
It's wonderful arriving home, getting upstairs and seeing her naked, or in any of her sexy outfits, laying in bed, playing with her toys and moaning in ecstasy... When this happens, I love to be around taking pics. Here u can see a compilation.
