Most stories involve young people when it comes to masturbation. Take it from me, it's not just for youngsters.
I too got my share of hand jobs perfromed on me in my late teens and twenties first by a neighbor girl and later by girlfriends and also prostitutes in my twenties. Now, after almost thirty years of marriage which means lots of straight sex with a woman, I've also have gotten my share of hand jobs from my wife. Even now, in my mid fifties, we often engage in mutual masturbation with each other and often times, I 'need it' and she doesn't. But, being the sweet wife she is, she'll always take care of me. On these occasions, she'll lube my erect penis with lots of KY, lay on her left side with her right legs raised and lay my penis against the inside of her left thigh and rub me against her thigh while stroking it. If feels so good when she does this and I always end up covering her leg with a nice load of cum and I'm always completely satisfied from this. My wife has always loved watching me ejaculate and on these occasions she is all eyes when it happens and I've always loved having my partners see me go. It is hard to beat a good hand job.
