As requested by my followers, I have written a conclusion to the story: Fries and a Happy Meal, Parts 1 & 2. If you would like to read those first, they are located here on Literotica.

Vince was tired of hiding his affair with his stepdaughter, Kenzie. She had taken to using it against him to get her way on just about everything. Kenzie was fucking obsessed with fries and Happy Meals, and Vince could barely stand taking her to the fast-food chain where Kenzie would order her Happy Meal and scarf it down like a little pig. There were so many things he hated about Kenzie, but she had one redeeming quality that made her worth something to him. She had the best pussy he had ever fucked, and lately, he had been banging her in the ass a lot as well.
If Vince had to guess, he'd say that he had fucked Kenzie three times as much as he'd fucked his wife, Anne, in the past nine months since the affair had started. She was the kind of wife that worked hard all day at her job in real estate, while Vince worked from home as a freelance writer for several finance magazines. He used to be a broker back in the day, but he had given all that up so that he could have a slower-paced life with Anne. Vince had spent countless nights unable to sleep as he painstakingly went over all the details of fucking Kenzie in his mind. Had he left any evidence? Did Anne somehow know already?
"Daddy?" Kenzie's voice came from behind him, and when he turned to say something, he could see that she wasn't wearing any pajamas.
"Kenzie, go put on some clothes! What if your mother wakes up and sees you like this?"
"You mean like this?" She climbed onto a couch near where he was sitting and stuck her ass in the air. "Daddy, I can't sleep. I need you to fuck me and make me tired."
"I can't sleep either, but we can't do this here where your mother could walk out at any moment and see us." He shook his head.
"Let's go in the garage then," she suggested, and he didn't see a problem with that. He grabbed her by the arm and roughly pushed her in front of him toward the garage. He could tell this gesture was turning his stepdaughter on. He bent her over his relatively clean workbench, stopping to make sure that the light was turned out and that the door was locked. He grabbed a clean rag from one of the workbench drawers and shoved it into her mouth.
"Not a sound out of you while I fuck you. You got that?"
She nodded.
"Your pussy belongs to me, Kenzie," he leaned down to whisper in her ear as he slid his rock hard dick into Kezie's 18-year-old cunt. The warmth and wetness of her pussy enveloped his cock, and he let himself go, enjoying the sensation of fucking a girl who was much too young for him. He pounded her pussy furiously, not caring about her pleasure or if she was getting off. There was a part of him that now hated her for turning him into what he had become. Before her pussy, he was a happily married man. Now, he was miserable, and it was all because of her young, tight, hole, and the things it made him do.
Her whimpering was sexy, and he knew that he was going to cum. He wasn't sure if she had cum yet, and he honestly didn't care. She deserved to be a little cum dumpster, and she was about to take another one of his loads. He moaned as quietly as he could as he finished inside of her and then pulled his cock from her.
"Now go back to bed. I'll see you in the morning."
"Daddy, I have a surprise for you tomorrow. Mom's going to be gone all day at an open house, and I have some friends coming over to get ready for my sorority event.
"That fucking sorority again?" Vince asked, sick of hearing about it. Ever since she had joined, it was all she talked about. Starting college had meant new friends and boyfriends for Kenzie. Vince realized he was worried that Kenzie would find someone her own age to fuck and stop fucking him.
"Yeah. I want you to meet my new friends."
"Okay, sure," he agreed, mostly to get her to leave so he could spend a few hours contemplating how he had become such a piece of shit. As soon as he had cum in her, he felt guilty. It was the same thing every time. He was so weak. He simply couldn't say no to sticking his cock back into Kenzie's warm, tight holes. Anne would kill him if she found out, and there was a part of Vince that knew that she would eventually find out. The truth had a way of revealing itself.
"Goodnight, Daddy," Kenzie cooed as she hugged him and gave him a sweet kiss right on the mouth. It took every ounce of restraint that Vince had to not fuck her again. He watched her naked ass as they made their way back through the house and to their bedrooms. Vince climbed into bed with Anne and found his cock was hard again. He tried to cozy up to Anne and stick his dick in her, but she pushed him away. He sat there with his hard cock in his hand and realized that this was why he had done it. He wasn't getting what he needed from Anne.
Vince could hear Anne getting ready for work the next morning, and he pretended to be asleep until she was gone. He was exhausted after being up the rest of the night with his cock throbbing for more sex. He thought about what Kenzie had told him about her sorority sisters, and his imagination took him all kinds of places that would have been unthinkable even a year earlier.
Anne called out a goodbye to him, and he waited until he heard the garage door close before he got up and made his way to Kenzie's room. She was asleep, but that wasn't going to stop him from sticking his aching cock into her lifeless body. He slowly peeled the covers from her body and confirmed that she was naked underneath. He climbed into the bed on his side and positioned her ass so he could get his dick into her easily.
He let out a sigh of relief as his cock entered her. She was wet even in her sleep, and that was a major turn-on. Unlike her mother, her pussy was receptive to him, and he pumped slowly in and out of her, languidly enjoying every stroke. He came hard in his sleeping daughter and quickly rolled out from underneath her covers. She had slept through the whole thing. He bent down to kiss her temple gently as if he wasn't the kind of father who had just used her pussy in her sleep.
That night, Kenzie's friends came over. Anne was taking pictures of them as he watched from the corner of the room, trying his best to look like he was on his phone doing something instead of watching their young, lean bodies striking pose after pose for the camera. He wanted to fuck every single one of them, and he was sure that Kenzie wanted that too. She kept catching his eye and giving him a naughty look that he was sure only he would see. She was subtle in front of her mother.
Vince suddenly wished Anne wasn't there so he could sink his cock into all five of Kenzie's friends before he fucked Kenzie again. He could feel himself stiffening as Anne put down her camera and told the girls to have a good time at the party.
"This isn't a frat party, is it?" Vince asked the girls.
"No, this is an all-girls gathering, Dad. It's called Cotillion, and we do it every year to raise awareness and money for children who have leukemia. We should be back later. Don't worry about us."
"Well, you all look very nice," Vince praised them. "Have a good time." He couldn't help but notice the slutty, little dresses Kenzie and her friends were wearing.
"Bye, Vince," Kenzie used his name instead of calling him Daddy in front of Anne.
"Bye, Kenzie's dad," one of the girls giggled.
"Bye," Vince replied, hoping that Kenzie's friend was into him.
When the girls were gone, he turned to Anne. She was already busy repotting a plant before he had a chance to have a conversation with her. She'd been distant from him, and he wondered if her emotional distance meant that she knew about what was happening with Kenzie. His guilt was starting to wear on him, and he could feel himself tightening up in the chest as he imagined what would happen if Anne found out.
"Anne?" he asked her.
"Yeah, Vince? Can't you see I'm busy?" she sounded annoyed, and so he mumbled something she couldn't hear and went off to the basement to go clean out the cupboards. He'd been putting that off, and he could tell that Anne didn't want anything to do with him. He worried all night about the reasons that Anne might be so distant, hoping that it wasn't Kenzie that she knew about.
He thought of Kenzie's body as he began moving cleaning supplies, appliances, and other odds and ends into the correct cabinets. His mind was racing with thoughts of Kenzie, so he had to take a moment to jack off in the basement, where Kenzie often played video games. He grabbed the blanket she used to keep warm in the poorly heated room that housed a couch, a few chairs, and a television and took a deep sniff.
The smell of Kenzie's body odor, perfume, and pussy filled his senses as he stroked himself to thoughts of his stepdaughter and her sweet, young body. Her scent drove him crazy as he thought about all of the things he would do to her next time he had her holes in front of him. His load erupted, and he knew it was wrong to shoot it all over her blanket, but he did it.
He needed to stop fucking Kenzie. Vince knew this, and yet he didn't want to stop fucking her. He needed her more than anything! She was the only thing about his life that was going right, and Vince didn't care if Anne hated him for the rest of his life. He was going to take what he needed to take.
By the time Kenzie and her friends came home, Anne had already pounded her sleeping pills and was sound asleep. Vince made sure to check on her a few times just to be sure that she was really passed out before he did the unthinkable and fucked her daughter again. He was annoyed with Anne, and this time Vince didn't care that what he was doing was wrong. He didn't care if Anne wanted to divorce him or even if she did divorce him. He knew what he wanted to do as he heard the girls come in, a giggling mess of laughter.
"Hi there, girls. How was your night?" he asked Kenzie.
