On a long rode trip once, late at night, was very sleepy behind the wheel. My wife, my daughter (15) and her best friend (15) were in the back seat. My two sons were in the front, everyone was asleep. I was fighting it when I felt a hand slide around the seat and began rubbing my crotch. It was my wife, or so I thought, it was too dark to see anything. I got hard and she tugged at my zipper and got it open, then my belt, then reached in and pulled my hard dick out and began caressing the head. She kept caressing and squeezing and rubbing until I shot a big wet load. She cupped her hand over it to catch the cum. When I was finished she tucked it back in and zipped me up. All with one hand. Fantastic handjob. I was wide now. The hand withdrew and back to **** she went. An hour later I pulled into a station to get some coffee and when I got out and looked into the back seat, my wife was on the opposite side from me. My daughters friend was on my side, sound asleep. To this day I do not know who gave me the handjob. Wife never mentioned it.
