It was going to be a busy day. My grandma Mary was moving into her new house and we needed to pick up her personal items from the old place. It was all the stuff my grandma would not trust with the delivery firm, she wanted it taken in the car.
I am David twenty years old and my mother is Ann. Grandma is sixty and my mother is forty. The running joke in the family is that I need to have a child now to keep up the twenty year gaps. It would not surprise me if it was mentioned during the long time we would have to spend together in the car. I was needed for the heavy lifting and my mother for the driving and her skill in packing.
My mother and grandma are very much alike in appearance. They are about five feet four inches tall compared to my five feet ten. Attractive faces are topped with auburn hair. Both have a few extra pounds but it looks good on them. I wouldn't like to guess their bra size but putting it crudely they both have a good handful. Grandma does not look her age and often when they are out together people assume they are sisters. However they have different personalities. My mother is easy going and carefree but grandma is quite formal and can be strict. You will never see her anything other than well dressed. I have to call her 'Grandma' rather than 'Gran' or 'Nan'. For mother it can be 'Mother', 'Mum' or even 'Mummy', any of these are OK with her.
It took us just three hours to get there. We had avoided much of the traffic because of the early start. Her new house is only minutes away from ours, it's the main reason why she picked it, so we had at least another three hours travelling to do on the return. I just hoped we would be lucky again, if not it could be nearer to four.
We had a hearty breakfast before packing. Mother insisted that before anything went into the car she wanted to get it all together so she could plan the loading. My first thought when we had arrived was that there was not much to be moved. I was wrong. Each room contained something that was going. Mother did a lot of pacing up and down and muttering under her breath. "No way. It's not going to fit in." Eventually she calmed down. After staring at it for several minutes she said "I have a plan."
She quickly explained it. The car would be fully packed except for the driver's seat and one of the rear ones. I would have to share a seat with grandma. I started to complain but was shouted down with "Have you got a better idea?"
I looked at all the stuff and thought about it. "No" was my simple answer. That made her smile and I was immediately put to work. Grandma just watched, happy that we now had a solution.
I thought we would be finished in half an hour but it was nearly double that. It was all the stopping to rearrange things. Grandma had a mixture of boxes, carrier bags and loose items. Every tiny space was now crammed with something. I just hoped we didn't get stopped by the police for being overloaded.
Mother did a final check of the house just in case we had missed anything. Nothing, so we were all packed. "Time to go" she said, happy with what we had achieved. I looked at the passenger seat and wished I had learnt to drive. I was now going to be stuck in the back, there was a lot more room in the front.
Until now I hadn't given much thought to how we would actually fit into the back seat. I suddenly realised that grandma would have to sit on my lap rather than us both being squeezed in side by side. I was outside the car thinking about it when mother prodded me. We needed to get going.
I got in and waited for grandma, I think she was having a last look at the house. She had shared it with grandad for nearly thirty years until his early death five years ago. I look a lot like him, the same muscular build. I have never been called handsome, rugged seems to be what most people say.
Grandma returned. She took a long look at where she was going to sit. "It's a good job I am slim and trim."
She eased herself in and mother closed the door. It was a tight fit but not as bad as I thought it would be. Without checking if we were OK mother was behind the wheel driving off. She put the radio on, it was a bit muffled because of all the stuff in the car. I had to shout to ask her to turn it up.
Everything was fine for the first twenty minutes or so until we hit a bumpy road. Not too bad but enough to make grandma bounce a little. My cock started to thicken. I closed my eyes and started to think un-sexy thoughts. Nothing worked, it just kept on growing. It's not massive, six inches on a good day but she must notice it. Grandma started to move, to adjust her position. It continued to grow to its full length.
She whispered "I know what men are like, but stop it if you can."
"I am trying to" I said. The road got a bit smoother but my cock stayed hard. Both of us tried to ignore it. However after another twenty minutes I felt her slowly start to rock on me. It was different from the movement caused by the car. She moved her bottom slightly until it was positioned nicely on my cock. With shock I realised what she was doing. She was now enjoying it. My cock found another inch.
My head was spinning. The best thing to do is ignore it. Pretend it is not happening. That is what I did until she held my hand and positioned it on one of her tits. "Are you shocked?" I didn't reply. I just nodded. "It's OK your mother cannot see anything." She then pushed my hand harder and I could feel a nipple in my palm. I moved my fingers to touch it and she removed her hand. I wanted to get inside but the dress was tight at the top so I would have to stay outside. I raised my other hand so that I could play with both nipples. I heard a soft moan as I felt them grow. My grandma had hinted in the past that her nipples were 'special'. I now knew what she meant, long and thick. I wish I could suck them.
She must have read my mind because she said "They should be in your mouth. That's not possible so you need to concentrate on my cunt." That shocked me even more. I had never even heard her swear before so using such a crude word left me stunned. I think she sensed my amazement. "I may be sixty but I am still a woman with needs. I am not sure if what we are doing is a good idea but since we are I want to enjoy it." I continued to work on her large nipples whilst I thought about what she had said.
I had just placed a hand on her lap when mother shouted "Are you still OK in the back. The ride is not too hard for you?" That made me jump.
Grandma laughed softly and wiggled her bum against my cock before replying "It's hard but I can take it." Nothing else was said. I was now concentrating on getting into her knickers. She made it easier by lifting her legs up and opening them wider. It looked uncomfortable but she had managed to rest her feet on some of the stuff packed in the car so her legs were in fact supported. I pulled her dress up as best I could but when she saw I was struggling she did it for me.
I could see her white knickers and the bulge of her cunt. I suppose I had expected them to be old fashioned and loose. These were small and tight. They reminded me of those my first girlfriend had on when she had let me finger her. That time was special and I hoped this was going to be as well.
"Do you want to stop for a break or carry on?"
"I think we should carry on. My leg is a bit numb but I am going to get David to rub it." As she said that she held my hand and positioned it at the top of her knickers. When she released her grip I slipped my hand in.
