I've gotta go do it!
I decided to take a night summer course in Human sexuality. It was 2 times a week for 3 hrs. I'm a 30 yr old working stiff with a wife and 3 small kids. I wanted to learn more about sex and all.
The gal who lived 2 doors down from us was taking the same course and I took her to school with me in my pickup. It had very dark windows. The instructor was a blunt man and didn't mince words.
One nite she asked me if I still masturbated. I told her I never missed a day. We had a good laugh about it. She then asked me if I would jack off for her. She had never seen a grown man's cock before less alone watch him jack off.
So being the gentleman that I am, I took my hard-on out of my fly and took my time masturbating and massaging my balls. Needless to say she was enthralled at my 7 1/2 inch by 7 inch cock. After I shot my load in some paper towels I had for such an occasion, (I keep paper towels because I would have mutual jack offs with my buds from time to time) she wanted to feel my still hard cock and balls.
I let her, and of course, she jacked me off. Her first time and was she ever happy about it. We masturbated each other after every class nite for the summer. Even when class was over we continued to meet and she would have a great time jacking me off.
When she went away to school, she could give a first rate hand job.
