I started reading some of those 'backseat' stories here on Literotica which were very hot and fun to read. Moms fucking sons, aunts fucking nephews and sisters fucking brothers but not many that had the more mature female counterpart of the family, so I decided to write one myself for fun!
It's not heavily story based like my other stories so it's more simplified, which results into hot, family fucking incest from the get go!
Sit back, relax and enjoy it! (And rub one out while you're at it!)

Nick, his mother Carrie and grandmother Aileen watched from a distance as his father Marc and his grandfather Patrick filled the center part of his father's custom Dodge Ram Promaster with tents and other camping equipment until it almost piled up to the roof.
His father always brought out his modified van when they went on their annual camping trip, it had enough space for the stuff they had to take with them and enough seats for the five of them. In the front the driver and passenger seat and way in the back a backseat bench that could easily fit three more people on it.
"You sure you will be able to survive sitting in the back with those two woman, Nick? It's gonna be quite a trip until we reach the hotel where we will sleep for the night!" Said Nick's grandfather to him, already taking his seat in the front next to his son.
"How could I not gramps, I don't mind the company from two beautiful ladies!" Responded Nick as he pinched and caressed both his mother's and grandmother's behinds through their summer dresses, his father and grandfather unable to see him doing so.
"Ha! Rather you than me and Dad over here Son! I wish you luck and I hope they don't chat your ears off with their annoying girly stuff." Added Nick's father. "Now get in, we do want to reach our destination a bit early!"
Nick gently took his mother's and grandmother's hands and guided them to the back of the van. "Ladies first!" He said polite.
Both woman giggled. "At least someone around here shows some interest in these 'two women'." Said Aileen loud enough so her husband and son could hear it.
Carrie climbed onto the backseat first before holding her hand out to her son, inviting him in. "Come on baby, we would like you to sit in the middle for this trip." She said seductively, giving him a wink at the same time.
Nick accepted his mother's invitation, he climbed after her and took a seat in the middle. He was surprised with how much room their legs had, it was rather comfy sitting in the back like this. He took a glance forward and noticed that they were literally blocked off from the front of the van. They could only hear his father and grandfather talk very softly, but being able to see them was impossible.
Aileen then climbed in after her grandson and took a seat beside him before closing the door. She placed her hand on his thigh and rubbed it gently back and forth.
Carrie quickly followed her mother-in-law's example and placed her hand on her son's other free thigh, moving it with same speed and motions as Aileen.
Nick smiled at both of them and could already feel the sexual tension hanging in the air. As bold as he could be he reached out to the front of his mother's and grandmother's summer dresses. He slowly brought them up to their waists, hearing them giggle again as he found out that they had their forbidden treasures right out in the open.
Another wicked smile crept onto his face as he looked left and right. To his left his mother's bald-shaven, tight, juicy pussy and to the right his grandmother's equally delicious looking cunt that had some nice trimmed hair, which made it even sexier. Both of their sexes were already sparkling with their female nectar.
Nick felt his cock starting to throb and harden. "Dad, I think we can leave now! We will shout when we need something!" He yelled as both of his hands crept down along the inner thighs of the two woman next to him.
Today was going to be a good day and a perfect start of their trip towards the camping location.

(Nick's perspective)
You might be wondering; how did I end up in this situation? How was it possible for me to flat-out expose my mother's and grandmother's vaginas and to caress their asses without getting scolded to death by them?
I'll keep it short and explain it to you, dear readers, because I know you all are here for the more 'practical' sides of this story.
A week before this annual trip my mother caught me jerking off, me thinking that both of my parents were out of the house. Instead of getting angry she quickly sat down beside me and before I it knew it her soft hands were around my rigid cock, giving me a hand-job like I never had before. As she jerked me off she flirted with me, telling me how much she loved me and that I was the only one that gave her any attention. She confessed to me that she was head over heels for me, a burden that she had been carrying with her for a long, long time.
After she gave me an orgasm of a lifetime we both cuddled up together, she telling her story why her sudden lust and love for me took over.
Apparently she was sick of the fact that my Dad didn't satisfy her anymore, the last few years he was busier with his father and friends to go out fishing or taking trips to their hunting cabin instead of spending some time with his wife and son.
She had always held herself together. My mother is quite a shy and timid woman, she's too much of a good wife so she didn't stand up to her husband. The plus side was that we got to spend a lot of time together, we did all kinds of things while Dad was away. Our relationship was already solid, but things like these brought us even closer together.
So finally, she simply snapped, her love and lust took over and that was the start of our incestuous relationship. We haven't gone all the way yet, this last week was limited to us making out, her jerking me off and me fingering her till she came, something we both thoroughly enjoyed.
Only during one of our incestuous 'plays' we got caught red-handed by my grandmother Aileen.
