It was August. We spent the morning packing the car. Our son, Mike was leaving for college. It was morning but already it was 90 degrees outside. Mike and husband, and I were getting pretty sweaty loading up the car. The trunk was already full and the back seat wouldn't fit much more. Mike went back in the house to get the last of his things.
I heard him come out of the house. I turned around and saw him carrying his 42 inch flat screen TV.
"Where are you going to put the TV?" I heard his father ask.
"I don't know, but I don't want to leave it. Maybe we can move some stuff around in the back seat."
I looked in the back seat. "I don't think so, son." Mike looked in the car. "We can put it in the middle of the front seat."
"Ok, college man," I said. "Then where is your mom going to sit?"
I could see on his face he was trying to come up with a solution. "I got an idea," he said. He opened the passenger side door. He put the TV in the middle. He then got in and sat down. "See plenty of room. Here mom sit next to me." I tried to sit next to my son. I could sit in the seat, but the door wouldn't close. Now, I am not a big woman. I stand about five feet tall and I only weight hundred pounds. It was my son taking up all the room. He was already over six feet tall and weighed around two hundred pounds. "It's not me that's taking up all of the room, it's you. This isn't going to work. Tell you what, leave the TV and when we come to visit you we'll bring it with us."
"No way," he answered as I got out of the car and stood by the door.
"Make up your mind, Mike, it's hot out here."
"Ok," Mike looked at me. "Ok, you can sit on my lap."
"Mike, it's a five hour drive to your college," his father said.
"I know, but mom doesn't weigh much. What do you say, mom. Would you mind sitting on my lap?"
'Ok, I'll sit on your lap. But if it gets too uncomfortable I want to stop at a rest stop." I said looking at Steve my husband. He agreed. "Ok, let's get our showers so we can get on the road."
My shower didn't take long. Since I would be sitting on my sons lap for five hours, I wanted to wear something real comfortable. My jeans would be too tight. Plus it was too hot to wear them. I looked in my closet. As I was going though my clothes I found a summer dress I brought. It was the short type with sleeveless arms. It buttoned up in the front. I unbuttoned it and put it on. When I finished buttoning it up, I noticed it showed my bra to much. I took it off again. I removed my bra and put the dress back on. I looked in the mirror. I really didn't need a bra. Even at thirty seven my tits were still perky. The dress was short. It only came to the middle of my thighs. I slipped on a pear of white panties. I took one last look in the mirror. I thought to myself. "For a mother of an eighteen year old son, I still looked good. I know my husband still likes what I look like. He tries to fuck me at least five times a week." I heard the car horn.
I ran downstairs, closed and locked the front door and headed for the car. My son was already in the seat. I sat down on his lap and swung my legs into the car. I looked down and notice my dress barely covered my thighs. It rode up pretty high. My son was wearing baggy shorts and a t-shirt. I closed the car door.
I was glad I was wearing this dress. I could feel the back of my bare legs on my son's bare legs. "How are you doing?" I asked my son.
"Fine, mom, you really don't weigh anything. No problem."
I looked over the TV at my husband. "Do you have enough room to drive?" I asked him.
"Sure," he answered. I could only see his head. "Can you even see me?" I laughed.
"Only your head, dear." Are you comfortable?"
I wiggled around on my son's lap. "Yea, I don't mind this at all."
I turned on the radio. As I was listening to the music. I started to feel something hard. I reposition my ass, but it didn't go away. I also noticed my son got real quiet. "It wasn't there when I first sat down." I thought to myself. Then I realized what I was feeling. My son was getting a hard on. I really didn't think about giving him a hard on by sitting on his lap. I could feel it still growing. "My god," I thought to myself. "How big is it going to get." I wondered what he was thinking. Does he think I can't feel it between the crack of my ass? I looked down at my legs. My dress had rose up a little more. I could almost see my panties. My son's hands was on the seat on each side of me. I wondered if he could see how high my dress had ridden up. I realized I like the idea of my dress being up so high. It gave me a little thrill knowing I could give my son a hard on. We only been on the road for about an hour. There was still four hours to go. I knew my husband couldn't see how high my dress was or he would be looking at my legs. The TV block everything from his view. I felt my son shift his body around. When he did his dick ended up on the back of my ass. I kinda wished he would try something.
"How you doing back there, son," I asked him.
"I'm Ok, mom, how are you feeling?"
