I have always enjoyed masturbating, but my wife had never expressed much interest in participating herself. Rather than making a big deal of it, I just decided to gently help her. As a part of sex together, I grabbed her hands and slid them under mine. I guided them to touch her breasts and nipples. I moved my hands, and made her fingers do what mine were doing. Then, I gradually removed my hand and let her continue on her own. She stayed and really seemed to enjoy it. She caressed the entire breast and gave out moans of joy.
A few sessions later, I tried the same technique on her pussy. I grabbed her hand and put it under mine as I gently massaged her pussy and clit. By now, she was growing comfortable with the idea. She took over and wildly rubbed her fingers right over the clit. She began to writhe up and down. She would have some of her best orgasms from grabbing her own clit and tits. I still need to start her out, but now we've progressed to where after I eat her pussy, she'll often move her hands in to take over. I can just sit back and watch my wife get herself off. I continue to encourage her verbally, but it is a tremendous turn-on for us both. I love watching her grab her tits and fingering her pussy. It is a fantasy come true in my bedroom every night. So, guys, teach your wives how to join the fun. And ladies, if you haven't yet, go ahead and try it. It will bring some of the best orgasms yet for both of you.
