When I read your post I couldn't believe my eyes.You know as a 54 year old married man I have always desired to have my wife masterbate in front of me and I do the same simoltaneously but exept for a few cases when we were younger and I insisted her to touch her vagina ,she has never continued more than a few seconds.If you have any Idea please let me know can you send a photo of your thighs while you are masterbating?
