Cliff is an 18-year-old high school senior, 6'4" 200lbs and good looking, his mom Katie is 36, 5'10" and 140lbs, plain to pretty, not the super-hot MILF, but a nice suburban mom. She is an RN at the local hospital. Tim is 47, 5'1" and 180 lbs. and is a truck driver at a brewery, His son Timothy Jr, TJ, is 19, 4'11" 125 lbs. and a freshman in college. He is a messy, unclean slob and a thief, but daddy sticks up for him and lets him get away with anything. Cliff has always wondered how tall Katie and he are, and Tim and TJ are short. Something is wrong with the gene pool.
It's Thursday morning and TJ is at school when his piece of shit car is finished at the repair shop and delivered to the house. It is as filthy as when TJ left it and must be shipped to him at school. TJ refuses to let anyone drive his baby and demands it be shipped to him. He has Katie's car at college, something Katie and Cliff fear how they will get it back. TJ doesn't take care of anything. TJ refuses to drive home and trade cars, he is spoiled, and Tim babies him.
Cliff has the ungodly task of packing TJ's car with all his stuff and cleaning out his room. Cliff hates TJ with unhidden passion. He gets trash bags and bags up all the cum soaked tissues, underwear and stuck together gay porn magazines and bags all the filth up and packs it in TJ's car. All his clothes, computer and crap almost fit. But he wants his foosball table and that will have to get packed in Tims car.
Thursday afternoon, with TJ's car all packed, the hauler arrives, and the delivery is set for 3 pm Friday and leaves. They all pack Tim's car and Tim makes sure that there is only the left rear seat for Katie and Cliff. Cliff has packed cleaning supplies for Katie's car and his go-bag, just in case.
Cliff overhears Katie talking to her sister Maggie on the speakerphone. "I don't know how to get rid of him," Katie tells Maggie.
"Boot his mooching ass out. You are not married, he isn't paying rent or any of the bills, you don't have sex anymore and when you did, you said his dick was so small that he couldn't even get it inside you. Fuck woman, pack his shit and be done with him. Send 'Tiny Tim' tiptoeing through the Tulips," Maggie never liked Tim, and it was showing.
"How?" asked Katie.
"Well, you and Cliff are having to pack up TJ's stuff. Just pack Tims with it. You said he has a load to pick up by TJ's school. Drop his crap off at his work and tell him after you're done, Simple," Maggie said.
Maggie was making sense to Cliff, he would pack Tims stuff and put it in the garage. Tim was not staying with them Thursday night and would pick them up and they would pack his car with the leftover stuff of TJ's.
Early Friday morning Tim arrived, and they packed Tim's car and got ready for their 7-hour drive. They will have to leave by 7am to get there with gas and rest stops. Katie and Cliff look at the room Tim has left them and know it is on purpose. Tim is a little asshole. Katie will have to sit on Cliff's lap the entire way.
Tim says, "Sorry, I had to get TJ's clothes and stuff from the shed, you will be fine."
Katie looks at Cliff and says, "I won't be too much for you, will I honey?"
"Mom, you are light as a feather." And with that, Cliff swoops in and picks Katie like she is weightless.
Katie laughs like a schoolgirl and hugs Cliff. They all climb in, and Cliff notices Tim had a scowl on his face as he picked up Katie. Cliff thinks 'Littleman syndrome' and climbs in and helps Katie get comfortable on his lap. The seatbelt doesn't go around Katie and Cliff tells Tim about it. Tim just turns up the radio. Asshole.
They start the drive, and Katie is trying to find a comfortable position and is moving her butt over Cliff's lap and starts to feel a bulge between her butt cheeks. She feels between her legs for the bump and feels his penis start to swell up and she looks at him and says "Honey, can you think of something to help ease your problem?"
Cliff is embarrassed and is turning red as even the motion of Katie turning around on his lap grinds her soft ass on his cock.
Katie is having to talk directly into Cliff's ear to be heard over the radio.
Cliff says, "I'm trying mom."
Katie mentions "Hey, I know. Think of granny Abby, nude and without her teeth in saying, 'Come here Cliffy, give your sexy granny a kiss, on my big flat tits, hahaha.' That would be funny."
"God mom, you will scar me for life. What a horrible vision you've planted in my brain." Cliff says. But that did the trick, either the horror or laughter got Cliff's mind off the arousal Katie was providing. Cliff had his arms around Katie's waist, and she didn't mind.
For Katie, it felt good to have someone hug her. It felt great to feel his hard cock swelling in her hand. Even if it was her strong, handsome son. God what was she thinking.
A girl could dream, couldn't she?
Tim pulled in to get morning coffee and donuts for everyone and got back on the road without letting anyone get out and stretch. Yep, still an asshole. Two more hours until the halfway point and the gas stop and lunch at noon.
They were ok for about an hour until the construction zone hit and the road was gravel and bumpy. The unevenness of the road sent a vibration through them, and Katie started getting aroused. She tried to hold back but a little orgasm slipped out. She didn't think Cliff felt it. She was getting more and more wet. She checked under her denim skirt and her panties were wet and the vibration was still going. She wasn't sure she was going to make it. Her small orgasms didn't squirt, just got her a little wet. If she had a big one, she would wash the seats and all of Cliff's lap in her juices. Please God no.
Cliff was feeling the vibrations also and felt how Katie was trying to hold out. He was sensitive to her feelings. He didn't know why he was, but he could read her, and most women pretty well. He felt her tense up and then felt her release her orgasm. He was concentrating on naked Granny Abby rubbing her tits with spittle drooling down her chin. Leering at him, rubbing her gray-haired matted snatch. It kept him soft. That's all that mattered. If he even thought of his mom, he got hard.
He felt her getting aroused again and he did also. They were about 20 minutes from the gas/lunch stop and it was getting bad. Katie's face was flushed trying to hold back orgasm number 3 and it was building up to be a big one. Shit, shit, shit. With her orgasm building and Cliff feeling her energy build, his was building also. Even granny Abby couldn't get him calm, he was going to cum, there was no way around it.
As Katie let loose, so did Cliff. Katie felt herself go over the edge and felt Cliff's cock erupt between her legs. She and Cliff bucked in unison, and she felt his hand under her shirt caress her breast. She let him while the orgasm had a hold of her but tapped his hand when they both calmed down. He moved his hand and said he was sorry. She didn't reply, best to let it drop.
They got to the truck stop, got out and headed for the bathrooms. Cliff brought his go bag just in case he could find wet wipes to clean himself up with. He went in and used the wet wipes and toilet paper to clean himself and packed his soiled underwear in a Ziplock bag. He met Katie outside and she had a ball of material in her hand and Cliff just handed her his bag.
"There's wet wipes and a plastic bag in there," he said.
Katie came back a minute later feeling fresher and said "Thank you honey, that little kindness is what makes you so special to me. I love you big guy."
They got back in the car, Katie again on Cliff's lap and tried to get comfortable again for the second half of the trip. Katie enjoyed Cliff's lap and even though she knew they would have arousal issues again, she was finally feeling alive down there, even if it was for the wrong reasons.
Cliff was feeling weird having his mom on his lap again. He was embarrassed because he came from her rubbing on his cock. He tried to stop it, but he just couldn't. He had to realize, she just felt too good on his lap, and he felt like he was taking advantage of her.
He said "Mom, I'm sorry for what I did back there. I know you are mad at me, and I can't say I'm sorry enough."
Katie turned to him and said "Oh Honey, I know you didn't do anything wrong. You are a good young man. It is the road and all the vibrations. You did way better than me. I don't feel bad about anything. Let's just put it behind us and we can forget it ever happened. Deal?"
"Sure mom, I love you. You are the best mom ever." Cliff was relieved.
The road was bumpy again, but they were able to giggle and laugh most of it off. Cliff better than Katie. She had a small one and Cliff felt it, but they said nothing about it. The dragon reared its ugly head again when they pulled off the freeway and hit county roads 2 hours into the last part of the trip. It seemed Tim found every pothole on the road and swung the car to "miss" them.
Cliff was holding on to Katie around her waist when they went airborne and she landed askew on his lap, her skirt riding up and more of her ass finding Cliff's legs. And the leg she was landing on felt damn good as it slammed into her clit. Katie thought 'Oh this is not good; this will make me cum again and hard.'
Cliff felt Katie go airborne and her landing on his leg felt extra wet. He thought he felt the skin of her pussy riding on his leg. It felt good, damn good.
It calmed down again for a few more minutes and then Tim hit another bad patch and instead of slowing down, he kept on going. Katie launching in the air again and Cliff catching her on his legs. One time, they both went airborne, and his cock came free of his shorts. He had been getting hard all this time, trying his best to control it, but having little luck. Now his cock free and Katie's skirt up around her waist, he was feeling every part of her sex on his cock. They were both just trying to survive the drive. He tried to get his cock put away, and she tried to get her skirt under her, but Mr. Cliff's wild ride was not over.
Tim was in the driver's seat laughing and didn't care about the damage he was causing in the back seat. He hit pothole after pothole, just to throw them in the air. Not even thinking of the damage he was doing to his suspension.
Katie and Cliff were still bouncing around and unable to get covered up when Tim swerved to avoid something and lost control and spun the car. Katie screamed and Cliff grabbed any part of her he could. She was breaking loose of his grip and the window was open. He had a hand on her torso and pulled her back into him as his hand on her leg slid up and met her hands pulling his cock to her hips.
