When I got a good job with a huge rise in paid my brother said he would help us move. We packed my pick up truck and when there was no way of putting any more in the box we began filling the cab hoping to make it in one load. By the time we had everything in the truck all we had left for room was began the steering wheel and right behind the driver in the back seat. My wife looked at me and said "We have two seats and three people how are we going to do this." I laughed and said "Well honey I guess Tom will have to sit on your lap wont he?" She give me that look all husbands know and said "I will be the one on his lap and he better keep his hands to himself."

It was one of those days when you could fried a egg on the road it was so fucking hot so both my wife and Tom had loose fitting shorts on, I thought if Tom don't get a good feel of the wife he would lose his chance. Tom said "Why don't you let me drive then she don't have to worry about me touching anything." My wife said "Ya right after you got a dui and have no license, there is no way you are driving our truck so get your ass in the truck so we can get it unloaded before dark." Tom got in and he had to help the wife on his lap before closing the door.

The load was kind of moving around so what should of been a two hour drive was going to take longer. I heard a little giggle from my wife and then her say "Here let me your not at the right spot." in a very low voice. I said "Is everything ok back there and honey I hope Tommy doesn't get a hard on as you ride his lap." All I got back was get your mind out of the gutter, he does have a boney lap thou." I thought was that a boney lap or a boner in his lap, I know Tom has a thing for my wife and she likes him as well.

After a good hour into the trip I hit some rough roads and I heard a moan and deep groan from the wife like she does when she about to have a orgasm so I said "You two ok back there?" and it was Tommy who said "It couldn't be better, she's as lite as a feather and I am enjoying having her on my lap bro." I said "Just don't knock her up ok?" My wife give a gasp and a long moan like she does if she trying to be quiet as she's coming. I hit a bad bump and I heard her give a grunt so I said "You ok honey do you want me to stop?" All I got was "No its ok, don't stop just keep doing it." in kind of a breathless voice from her.

After a good 20 minutes more I heard her say "Oh no you didn't did you? Not in me, oh Christ it's still going isn't it?" I don't think she thought I could hear her but it was hard but am sure that's what she said. In total it took us over three hours to get to the house I had rented and as soon as we got there the wife was saying "Give me the key I need the use the washroom." I opened the door and handed her the key and she went by me on the run with something running down her legs and as I looked at my brother's lap his shorts were dripping wet and I could see cum on them as well. I knew he had fucked my wife on the way over. I wondered if he had knocked her up as well, she don't like pills so she uses a diaphragm but it is packed and she had no protection.

That night I asked her what happened in the back seat she began to cry and said she could feel him getting hard under her and she felt horny all day and it just happened he had his hands on her thighs and it felt so good and when I hit a bump his fingers slip up and bump my pussy through my panties and it was like a dream after that. She told me it would never happen again, but I have a feeling that just may of started something that she cant control. Now I may end up with my wife having his baby and not mine. I do love her but I don't know if I can handle this.
