My wife has quite a high sex drive.
We have sex about once a week. Friday nights are usually the best. However, she is often very horny about three or four other times and we've come to an arrangement that suits us both.
She will tell me straight up if she is in the mood and, after a bit of TV watching, we head off to the bedroom. She lies down naked or near naked and starts to play casually with her pussy. Often times, she will have a dildo or vibrator within easy reach, for later use.
I will stand at the side of the bed, near where she is lying. I will have my pants and underwear off. Sometimes I will be completely naked depending on the weather or if I've just had a shower. I will have my phone with me and just casually scroll through the news, emails or just check tomorrow's weather.
My wife will reach up and gently grab my balls and fondle them as she starts to work on her pussy. Her pussy will usually be nice and hairy. She will spread out her legs which allows her cunt to open further.
