A few years ago my wife was going through menopause and her pussy became very dry and she lost interest in sex. I began masturbating regularly, almost every day. To vary the routine I often took a small hand towel, soaked it in hot water and rang it out so it was moist and warm, then I would lubricate my penis with a lot of hair conditioner, which was thick and creamy, then I would wrap the warm moist towel around my hardon and place it between the toilet top and bring the lid down to apply just enough pressure, then on my knees I would begin to fuck this artificial pussy. It was really a good substitute for getting off, when I would come, the load would go right into the bowl (no clean up problems). Sometimes I would use a lubricated condum, often better because the towel was sometimes a little rough.
I might add, that after my wife's problems were over, she became hotter than ever, now she can't get enough and keeps me quite busy, three or four times a week and leaves me little time to jack off.
