It was a long week for Seth. It was the week of his sister's college graduation, and what that meant was....lots of family in one place at one time. All families have their problems, but Seth really thought his had more than their share. His parents had divorced several years ago. Seth had been living with his father 250 miles away from where his older sister had been living with their mother. This week he rode up with his father and stop-mom to the graduation in his father's Winnebago RV. The RV was roomy and comfortable. It was really a lot nicer than many fancy hotels. His loft bed was above the driver's seat in front of the kitchen area.
Seth's dad, Carl, had recently remarried. His dad was in his fifties and his new step-mom was almost 10 years younger. Carl was a serious man with a graying full head of hair; if he wasn't working he was probably golfing. Seth's step-mom, Laura, was definitely a blond. She had an annoying giggle she used after about every third sentence that sometimes made Seth want to grab her by the ear and shake her. She wasn't that bad though, really. She could be nice sometimes. She was attractive; even though she wasn't fat Seth thought her breasts were small in comparison to her thick thighs, round butt, and wide hips. She had a naturally large frame and her meaty thighs often strained against the pants she would wear. She was a tall woman, Seth was 5' 11" and he was sure she was every bit as tall as him.
The graduation was to be held on the following day, Sunday. The worst day of the trip so far had been on Tuesday. The entire family had gone to Olive Garden restaurant. That meant Seth's real mom, Patricia, and his step-mom at the same table. They hated each other. His dad had been fooling around with Laura before his divorce and Seth's mom never forgot or forgave. Well, to make a long story short, after several bottles of wine the two women got into a fight in the parking lot on the way out. Patricia grabbed the younger but larger woman's purse and threw it out into the busy street. The cars swerved and honked their horns but the rear tire of a sedan hit the purse and destroyed it. That night Laura went the police station and filed a restraining order against Patricia.
Now it was Saturday night and the moon was shining in through the windows of the Winnebago. Seth stripped off his jeans and shirt with the lights off. His dad and step-mom were out drinking, he guessed. Knowing them, he knew they might be out late. He slipped off his boxer shorts and decided it was a good time to shower while everyone was away. The cool air felt good on his naked penis and he scratched himself. He stepped into the tiny RV shower and turned on the water. It wasn't much more than a trickle but it was warm. As Seth washed himself he noticed his step-mother's black panties hanging beside the towel on the rack. He grabbed them and put them to his face inhaling the scent. They had been worn and he could smell the musky scent of her womanly juices. He stroked his now stiff erection up and down several times with his soapy hand. He glanced down at his swollen purple head and then stopped.
"What am I doing, thinking of Laura like this?" He shook the thought of her sexy round hips out of his imagination and jumped out and dried himself.
He walked, still in the nude, to his bed and picked up his IPod. He put the ear buds in, jumped under the cool blanket and closed his eyes enjoying his music. He was sleepy and drifted off.
The next thing Seth was aware of was the noise of the door rattling. He peeked out the tiny side window and didn't see any sign of his father's jeep that they had towed with them behind the RV.
"Seth!" A hoarse whisper came from outside.
"Mom?" Seth was a bit confused.
"Open the door, I need to talk to you."
"Mom, Laura has a restraining order on you. Do you want to go to Jail?"
"Just open the door!"
Seth jumped down off the loft bed, still in the nude, and tiptoed to the door. He unlocked it and then scurried back to his bed. His penis flopped from side to side and he jumped up under the blanket just as Patricia entered. She walked over and leaned against the high bed that was at her head height. Patricia looked like she had dressed with intentions of going out. Her eye makeup was streaked and her eyes puffy like she had been crying. Patricia had light skin, brown eyes, and short, dark hair in a bob cut. She didn't have a perfect body -- she could stand to lose five or ten pounds -- but she had full breasts and a thin waistline proportional to her curves. She wore a white button top that shared a fair amount of creamy cleavage and a short black skirt. She had on knee-high black boots over her bare legs.
"Seth, I'm worried about the graduation," she blurted. "I don't want Laura there. This is my daughter's graduation!"
"Mom, you shouldn't be here."
"Can you talk to your father about Laura and the graduation? Do I have to stay away from my own daughter's graduation because of that whore?!" Patricia's normally pale face looked red even in the dim light."
"Mom, calm down." Seth took a heavy breath and exhaled.
"I don't know what to do," Patricia's lip quivered and her dark eyes were misty.
Seth silently searched his mind for an answer. Then without warning, there was the sound of crunching gravel under car tires. A blinding flash of car lights swept across the inside wall from the window. Seth and his mother both froze in terror. The vehicle stopped in front of the RV and then one door slammed followed by another. The unmistakable giggle was the first sound they heard after the doors closed. At that point Seth and his mom looked at each other with an identical look of panic and they knew it was Carl and Laura.
"Shit, shit, shit," Patricia whispered with an uncharacteristic foul mouth. "I have to hide!" With an adrenaline fueled leap Patricia jumped up on the bed and slammed her back into Seth pushing him to the corner. She pulled the blanket over her head and body trying to make the extra lump in the bed as small as possible. The hard soul of her boot scraped down Seth's bare leg so hard it almost drew blood.
"Fuck, mom that hurt!" He growled. "er...sorry for swearing,' he whispered under his breath.
"I'm sorry, honey," Patricia hissed. She reached down and wrestled her boots off with two quick motions and pushed them into the corner under the blankets. Patricia resituated with her back to Seth. They were both facing the door and Seth's chin came over her head that was buried under the blanket. Their bare legs came together and her skin felt cool against his legs. When their skin touched Seth remembered he was naked. It left him with a horrified feeling like those bad dreams of being naked in public. Seth pretended he was asleep.
Carl and Laura entered the RV and slammed the thin door shut. They smelled of alcohol even from feet away. Laura pulled Carl by the arm to the couch on the far side of the kitchen.
"Carl, remember what you said...Carl," Laura erupted with her trademark giggle. They both fell on the couch together and Laura was whispering something in Carl's ear.
Seth opened one eye and looked over at his dad and Laura. His mother was shaking a bit under the blanket but her skin now felt hot against his legs. He opened the other eye realizing that the couple not 12 feet away was paying no attention to him. Laura was wearing a flowery one piece dress with thin straps over her shoulders. The fit of the dress made her butt look even larger than it really was. Carl was lying back on the couch. Laura straddled Carl while facing him and began a slow rocking motion. Carl slipped one strap off her shoulder and tugged at her dress exposing her right breast. Her breast was pointed with a high, small, pink nipple. Carl bit at it gingerly with his teeth. Carl slipped his jeans off to the floor and one sock came off with them. He flopped his other leg with the sock still on until it too fell to the floor. He slid both hands under her dress, lifted it up, and took a full handful of meaty flesh. Laura slid up and back rubbing his cock into her crevice. She threw her head back and then giggled before her eyes rolled back into her head. Seth looked on as if watching a train wreck. It was horrifying but he couldn't look away. Laura rose up, reached between her legs, and guided her husband's throbbing penis to her entrance. She came down slowly on it with a whimper and a giggle.
At that second Seth realized he had a rock hard erection. He was breathing fast and felt dizzy. He tried to pull away from his mother who had her back pressed into him but he was against the wall. He shifted as quietly as possible and his hardness was in contact with her warm flesh. Her dress had pulled up when she jumped under the blanket. Again he squirmed and found his penis had moved to rest naturally between her legs.
"Sorry mother, I'm really sorry," he breathed with his lips to her ear. Her only reply was a subtle nod of the head which Seth didn't know how to interpret.
Across the room just feet away Laura was riding up and down on Carl's firm shaft. She was beginning to be quite vocal with high pitched squeaks and squeals. Seth couldn't help but watch them. Laura now had her dress pulled down exposing both perky breasts. The dress was bunched around her waist and with every humping motion her round ass would jiggle and shake.
