About a year ago a friend of mine called me and asked me to do some repair work on his farm. As I helped him from time to time, this was not an unusual request. He had to be out of town for a few days but his wife and children would be available to help me if needed. I agreed to go out the next afternoon after I got off work.
Arriving at the field, I noticed the machinery was parked at the far end of the field, near some shade trees. As it was quite warm, I appreciated this. I laid some cardboard down and crawled under the machine, laying on my back and began to make the repairs. As I worked, my jeans slid down a little on my hips and my T-shirt slid up, exposing my stomach. I laid some bolts and nuts on my stomach while I worked. After about a half hour, I heard Janice, my friend's wife drive up. She's a petite blonde, about 35 years old. To look at her you would never know she's had five kids. We talked a little, then she knelt down and began to help me. Her knee went between my legs as she leaned forward, gently touching my crotch. My cock began to swell up in spite of my efforts to think of something else. Janice was a very quiet conservative woman, and I was somewhat embarrassed of the rise in my jeans.
My cock was rock hard by now and my pants had slid down so far that I was in danger of the tip of my dick becoming exposed. All I wanted to do was crawl out from under there, but I couldn't with her knee in the way. I began to quickly finish the repairs. As I reached for one of the bolts laying on my stomach, Janice grabbed it, trying to help me. In the process, her fingers came very close to my hard cock. She seemed oblivious to my embarrassment. As she handed me the last bolt, her fingertips brushed against the end of my now raging boner. I was getting very excited at this point. My wife had been very ill and I had not had sex in a long time. I felt like I might cum at any time. I was relieved when Janice started moving back, as I thought I might get up and walk my hard-on off. She laid a hand on my thigh to steady herself. I didn't know how much longer I could go without relief.
Suddenly I felt hands undoing my pants and my cock being exposed. I was too surprised to say anything when Janice wrapped her lips around my throbbing member. She was the last person I would have ever expected to do anything like this.
