Chapter Text
The Mitchell family life had gotten crazier by the day. Amy felt like she was being ingenuous somehow whenever her dad touched her behind her brother’s back. Whenever she and Josh did something and she knew her dad may be watching on the cameras she still couldn’t find.
But she couldn’t find it in herself to stop any of it. She was powerless.
“Hey sis, come in here,” Josh called from his bedroom when she passed on her way back from the bathroom in her pjs.
Nervous, Amy stepped inside to see her brother sitting at the foot of his bed in his boxers. “What are you doing?”
He shrugged with a little grin on his face. “Nothin’. Just thinking about… you know.” As he shifted, she could see his hard cock flopping in his thin boxers.
“I just took a shower,” she complained. But she still stepped closer, her body remembering the feeling of his dick inside. Her pussy clenched on nothing wistfully. “And dad’s home.” That somehow made it simultaneously worse and hotter. She wondered if he was logged into the cameras even while they were all home. Or was he lurking around any corner waiting to watch in person? She wondered if they would ever lay everything out in the open.
“Just get me going,” Josh begged in a horny teen guy way. “Then I can take care of myself tonight.”
Amy wordlessly huffed and pulled down her top just enough to flash him a sight of her bare tits. After a moment, she pulled her top up again. “Good?”
“Come sit on my lap for a second,” Josh said, reaching out his hand.
She shouldn’t have. She should have resisted. It was probably time for all this craziness to end. But she knew none of them would allow that. So, she walked into her brother’s room, shutting the door, and sat backwards on his lap, slowly grinding her covered crotch on his, imagining she was riding his dick until they burst.
They moved like that together, both tempted to just remove the closes and go at it, when they heard the heavy footsteps of their dad coming up the stairs. With a frightened gasp, Amy jumped off of her brother and ran out of the room, beelining back for the bathroom so she could splash cold water on her face before she had to face her dad in the hallway.
That wasn’t the first or last awkward ‘almost’ moment by a long shot. Just the other day she was peacefully reading in the living room and her dad walked through on his way to work. He paused, hovering over her shoulder, and asked, “What’chya reading?”
“Um, The Scarlet Letter,” she answered, realizing how low her tank top rested on her breasts.
Her dad seemed to be noticing the same thing because the next second he was resting his hand on her shoulder and slowly letting it slide further down. “How… appropriate,” he said as his fingers fished out her nipple and teased it right out in the open.
Only Josh thundering down the stairs made Stuart take his hand out of her shirt. She coughed awkwardly and shot up from the couch, going to pour herself cereal in the kitchen. Of course, that’s where Josh was headed too, eyeing her tight skirt. Why had she decided to wear it around the house? She was basically asking for it at this point.
Josh came up behind her slightly bent over the couch and pressed his crotch against her behind, feeling up her ass and hips with his hands.
“Stop,” she hissed behind her as their dad languidly followed her into the kitchen.
“What are you kids up to today?” Stuart asked, walking in and grabbing an apple from the bowl in the center of the island counter. “Not staying cooped up inside, I hope.”
Josh stayed nearly pressed up against Amy but angled himself, so it looked innocent to their father. Little did he know. His hand still slid down along the curve of her ass.
“No, ‘course not,” Josh said smugly. “I’m meeting my friends at the square later. What about you Amy?”
Amy opened her mouth to answer just as Josh slipped his hand under her skirt and started feeling up her pussy from behind her. “I-I don’t know. I think I’ll just finish my book. Maybe read outside.”
“You could use some sun,” Josh said.
“Just don’t forget sunblock,” Stuart said. “Well, I’ll see you guys when I get home. I’ll bring dinner.”
“Okay, bye,” Josh and Amy called after him. Amy’s ‘bye’ went higher pitched when Josh chose that moment to slip his hard cock into her from behind.
“You motherfucker,” she hissed as he grabbed her hips and started fucking her over the kitchen counter.
Josh chuckled. “More like a sisterfucker, but whatever.” He grunted as his skin smacked up into her ass.
Amy tried to hold back her sounds, even after hearing the front door open and shut, knowing their dad was driving to work and not possibly watching them this time. But this still felt dirty and clandestine.
Her body felt every intrusion of his cock in her pussy with a taboo thrill and soon enough she couldn’t hold her noises back. She let them tumble out of her mouth, a litany of moans and mewls and deep whines. And when she came, her orgasm was roughly cut off because Josh had to pull out and spray his cum on her skirt.
“Fuckin’ hell, Josh, now I have to do laundry, or this’ll stain,” Amy complained, already stripping her skirt and panties on her way to the laundry room.
True to his word, Josh did go meet with his friends. And true to hers, Amy finished The Scarlet Letter in the living room and on the back porch.
Only things turned upside down when Josh came home and didn’t immediately see anyone in the house. His dad’s car was in the garage. He knew Amy’s friends were all away, so she didn’t have anywhere to go. But no one was in the living room, kitchen, or his dad’s office and the whole house seemed to be too quiet. Seemed.
Pulling his earbuds out and setting his skateboard in the hall closet, Josh wandered upstairs towards Amy’s room, hoping she’d be up for another round after this morning. He was already hard just thinking about it.
But she wasn’t in her room. Or the bathroom. For a second, his horny brain thought she might already be in his room. But as he headed there, he passed his dad’s room and heard something in between heavy breathing.
“…fuck yeah… you’re daddy’s girl now…”
This made Josh stop. The door wasn’t shut the whole way, so he didn’t have to twist the knob or make a noise to push the door open enough to peak inside. He didn’t even know why. His dad was a single man with a good job and probably had some younger girlfriend over and they were roleplaying or something. Amy obviously left and Josh was already out. What was the harm?
But that feeling of ‘what if?’ didn’t go away, especially when he knew what he and Amy had been doing when their dad wasn’t around.
His darkest thoughts were confirmed when he finally got a look in the room and saw his dad flat out his back with Amy moving her mouth up and down on his cock rapidly with his hand tangled in her hair.
Josh froze solid as he watched his sister slurp on their father’s dick like it was her job. What the fuck? How long had this been happening? Why hadn’t Amy told him? Who started it? did this mean their dad knew about what they’d been doing? Was this all some sick twisted coincidence? Or an even sicker and more twisted triangle?
His thoughts were jolted when Stuart pulled Amy off of his cock and he saw a string of saliva still connecting the two together.
“Daddy wants that tight pussy now,” Stuart said hungrily. He flipped Amy onto her back and stood on his knees in front of her.
Her knees connected, shielding her bare center. “Dad… it’s getting late, Josh’ll be home any minute.”
“And so what? You want your brother’s cock instead?” Stuart asked her mockingly. “I thought you got enough of him this morning.”
Josh’s blood turned to ice then. So his dad did know about them.
Amy’s face turned red. “That wasn’t what I meant.”
Stuart planted his hands on her knees and pried them apart, exposing her wet and throbbing heat to both his and Josh’s gaze.
He placed his hand against her and rubbed circled across the length of her slit. Amy uncomfortably whimpered and shied away but Stuart didn’t let her get far. He bunched up her tanktop under her tits and kicked her thighs further apart so he could have room to impale her on his cock.
Amy inhaled sharply for air as he penetrated her. And she just lied there as her dad started fucking her as if she was his plaything.
Josh’s pants grew tight again as he watched his sister get fucked by their dad while he muttered lewd things to her.
“Fuck, so tight, my little girl made just for me, just for my cock. Gonna make you cum so hard, harder than your fucking brother.”
Josh felt an inkling of indignant anger at his father’s incendiary comments. But it was dulled by the sight of Amy’s perky tits bouncing with every thrust of their father’s cock.
And his own hard dick certainly forgot to feel mad when Amy’s body started to shake with an oncoming orgasm. “Ngh, daddy!”
“There it is, cum for me, little girl,” Stuart said crudely. “god, you just got so much tighter. It’s daddy’s turn to cum.”
“Please pull out, Daddy,” Amy begged.
It didn’t look like he was going to listen to her. But Josh was glad he did. If he didn’t get to cum inside, neither should their dad. And he certainly didn’t mind the vision of cum shooting onto Amy’s tits.
Amy lied there, her cum covered chest heaving with her panting. Stuart stood from the bed and went to get a washcloth. As he went to his bathroom, her eyes fell to the door and saw Josh. He stared right at her while her eyes widened at the sight of him. He could practically read her mind and know what she was thinking.
Fuck.
