I had just finished packing my stuff, my dad and i carried all the boxes out to the car whilst my mother was getting ready. Our car wasn't too big, there was one big box on the left side of the backseat, and four smaller ones stacked on eachother in the middle seat, leaving only the right seat open. We had another 2 medium-sized boxes in the passenger seat. I didn't think that my mother was gonna sit in my lap, so i just sat down in the available backseat and my dad sat down in the driver seat. As i was sitting there waiting for my mother to come out i was looking at my phone, i was just about to type in Literotica but i heard the front-door close, so i just put my phone into my pocket. As she walked towards the car she had this weird look on her face, i think she scanned the car and looked for available seats, she stopped next to me and leaned into the open door and asked my dad.
"Where do i sit?" and both me and my dad looked around thinking of a solution. Now i've read a lot of Incest stories on Literotica, Mother and Son to be accurate, i've never seen my mother as a sexual object or a woman, i've just seen her as a mother, as i was thinking this it kind of slipped out of my mouth and i said.
"You can sit in my lap." She looked at my dad first and then she looked at me and said.
"You sure?" I just simply nodded and said.
"Of course i'm sure."
She was wearing a kind of white/beige summer dress with green leaves on it, it wasn't the kind of white where you could see-through. I was just wearing a pair of shorts, nothing particular. She sat down on my lap and i could feel the warmth of her body through my shorts, and i could smell her perfume. She closed the door with her and we took off.
After about 10 minutes or so my mother asked my dad.
"How long is this trip gonna take?" and my dad kept his eyes on the road and answered.
"eeh... Not entirely sure, but i would guess about 2 hours or so." My mom just turned her head right and looked out through the window. After about 30 minutes had passed my cock grew a little, not enough to make her notice, but i was worried she might notice it if it grew just a little bit more. I had never had a girlfriend before and i was still a virgin, and on top of that, i hadn't masturbated for a week, so i was pretty horny by now.
