Finn stood impatiently at the fitting room door, a pile of clothes clutched in his hands. He glanced down at the garments, his mind wandering to the reason he was here in the first place. Kayla had caught him having sex with their blackout drunk mother, and now, she held all the power. If Finn didn't obey her commands, she'd release the video to everyone they knew.
As he waited, he heard the sound of the fitting room door open and close. Kayla emerged, her eyes sparkling with mischief. She was dressed in a revealing outfit that showed more than it hid, and Finn's heart skipped a beat. She had pink shorts that showed almost her entire butt and a micro bikini top that couldn't even cover her bikini tan lines. She knew exactly what she was doing.
"Come back here, Finn, I got more clothes for you to carry," Kayla cooed. Finn followed reluctantly, his eyes unable ignore the way her ass swayed as she walked.
Inside the fitting room, Kayla tried on several outfits, fully aware that Finn was seeing her naked even for brief glimpses, and each outfit more provocative than the last. She'd slip on a tiny skirt or a low-cut top, then turn to face him, her eyes daring him not to look away. Finn tried to maintain his composure, but it was becoming increasingly more difficult.
"You know, Finn," Kayla said, her voice low and sultry, "I've been thinking. Since we're spending so much time together, we should really get to know each other better. Maybe... share some experience," she said as she dragged her finger down Finn's chest.
Finn's knew where this was headed. He shook his head, and scolded her, "No, Kayla." His voice was firm and commanding, but she just laughed, her eyes glinting with a wicked gleam.
"Oh, I think you will," she teased, her hand reaching out to touch his cheek. "You see, Finn, I have the video to keep me company. And if you don't obey me, I'll make sure everyone sees it."
"So, what? Are you gonna have sex with me? Is that my awful punishment for having sex with our mom?"
Kayla huffed a short, sharp laugh, "You wish it ended there." She turned away from him and pulled down her pink shorts.
Finn didn't care anymore, he looked at her bare bubble butt with impunity. After all, she clearly wanted him to ogle over her. She slipped on her own pair of shorts and pulled her shirt over the micro bikini she'd neglected to take off, the tag still poking out of her collar.
Kayla turned to face Finn again and continued, "But, no, no sex yet. First, I still wanna know why mom fucked you."
Finn let out a heavy, exasperated sigh. "I told you, she doesn't remember and that was the only time we ever had sex," he said in his defense, "What else do you want me to say?"
Kayla had been convinced there was more to his relationship with their mom, but he'd said all there was to be said. She was drunk and feeling self conscious, and he was there for her. In Finn's opinion, she would have had sex with anyone that night, and there was nothing more to it. But still, Kayla kept asking him for more as if there was some secret he was hiding.
Of course, his defense did not get through her thick skull.
"I just think its a little weird that mom would suddenly come onto you, just because she's drunk. She's drinks, like, every weekend. Why now?" Kayla leaned on one leg, her hand at her hip, "You two probably fucked when she visited your dorm last year, huh?"
There was nothing he could say, so Finn swallowed his frustrations and gave up. He reached out and grabbed the bikini tag she'd forgotten and yanked it off in one, quick tug. "You forgot this," he said before tossing it to the ground, "Can you just drop it and finish up here. We've been in this store for two hours."
Kayla rolled her eyes and fluffed her plume of long, wavy dark hair. "Whatever, I gotta get ready for work soon anyway. But, you better hope dad never finds out, cause you won't be able to change subjects like this on him."
Their father, David, was none the wiser to his wife's infidelity. Finn knew about the swinging and extramarital sex his parents had, but something told him incest wasn't on his dad's shortlist of excusable offenses. Kayla was right, Finn needed to cross his fingers that their dad never found out.
As they left the fitting room, Kayla slipped her hand into Finn's. The last thing Finn wanted was someone to see him holding hands with her but, of course, he couldn't say no. They walked out of the mall, the sunlight blinding Finn as his eyes adjusted from being in the dim store for so long. He glanced down at Kayla's hand, still intertwined with his. She walked him around like he owned him, and he had no choice.
To add insult to injury, their mom seemed to think Finn and Kayla had suddenly gotten over their sibling rivalry and become friends. She even took credit for their good behavior, chalking it up to her 'good parenting.' Finn wondered how his mother would rate her parenting if she knew her son had been balls deep inside her, of which she seemed to enjoy, and now her daughter was slowly seducing him.
Once they got home, Finn dropped Kayla's bags in her room, which she thanked for by shooing him out of her bedroom so she could get ready for work. Of course, he had to bring her.
Finn shrugged off to his room, collapsing onto his bed. He'd spent the entire day catering to Kayla's every whim, but now, as he lay in silence, he couldn't help but think of someone else.
Miranda. His mom.
Finn's thoughts were consumed by the memory of her naked body, her soft skin, and the sweet scent of her rose perfume. He had an hour before Kayla had to go to work, which was plenty of time to relieve himself. Finn tugged his pants and boxers down to his ankles and his cock sprang out, already at full mass. He scrolled to his favorite porn site and began swiping through a myriad of photos, though he couldn't get his mom off his mind. Finn closed his eyes and Miranda's naked body came back into sight. He could remember how she felt when he was inside her, and his cock ached to feel it again.
Finn's fantasy was abruptly ended when his phone blared to life with Sarah's unique ringtone, though he didn't rush to answer. With Kayla's blackmail looming over him and crowding his schedule, Finn had no time for his girlfriend. It had been weeks of distance between them and he just didn't have the mental space to talk to her. Finn muted his phone and tossed it to the side, her contact photo still visible on his screen.
Stars sparkled under his eyelids as Finn rubbed his palms over his eyes, as if trying to rub away his thoughts. A soft creaking noise perked his attention, but Finn was suddenly jolted out of his trance when he realized the noise was his bedroom door opening. His older sister, Mia, poked in her head slowly and her eyes fell upon Finn, whose cock was still out and not at all soft. Precum oozed down his shaft just as he saw her eyes drop down to see it, though she didn't have any signs of embarrassment on her face.
Finn scrambled to yank his pants back up, though Mia did not act with such urgency. She left the door cracked enough to speak through and shouted through a whisper, "Sorry! Should I come back later?"
"No, no! It's okay, I just hadn't gotten dressed yet!"
"But, you just got home?" Mia challenged. It was a blatant lie, and easily shot down.
Once Finn had his pants on and buttoned, he called to her awkwardly from across the room, "Okay, you can come in."
