Kenneth Ulrich pulled his car up to a stop in front of the Greenfield house, his mind as he got out mostly going over all the apologies he was planning to make for being late in picking up his stepdaughters. He really hadn’t meant to get so sidetracked at the office this afternoon, but one thing after another had kept popping up, and before he knew it he was nearly a half-hour late.
It might have been easier if either Heather or Andie could drive, but Heather had failed her driving test three times and didn’t seem to like the process, and Andie had never even mentioned wanting to try. And Paula couldn’t drive them either, since her license had been revoked after a little incident last year involving a dented fender and an open beer bottle.
Well, he thought as he approached the house, at least it’s only their friends’ house I’m late getting them from. They probably won’t complain too much.
It was this thought that comforted him as he rang the doorbell. Chances were, in fact, that the girls would be glad for the extra time to spend with their friends.
Paula answered the door, giving him a polite smile. “Hi, Kenneth,” she said, using the name he had insisted she call him. “Heather and I were just chilling.” She ushered him inside, to where Heather was waiting in the living room.
And immediately, his eyes were drawn once again to the expanse of legs Heather was showing. So smooth, so sexy... flashed through Kenneth’s mind. He quickly put a lid on that train of thought like he always did. He’d gotten pretty good by now at pretending his nubile teenage stepdaughter didn’t excite him every time he looked at her.
He had to keep pretending as she stood up and stretched her short and slender body, and turned to look up at him with those beautiful green eyes behind her cute little glasses. “Hey Kenneth,” she said. “I’ll be ready to go in a second. I’ll just go get Andie.”
Was there any jury in the world that could have found him guilty for staring at Heather’s little round ass in those short shorts as she hurried out of the room?
“I hope I didn’t keep you waiting too long,” Kenneth forced himself to say to Paula as the moved back to the entryway to wait at the bottom of the stairs, hoping he didn’t sound as stupid as he felt.
She shrugged and said, “We sat around watching bad TV for the extra time. Could’ve been worse. We could’ve been in class.”
He managed a laugh, just as Heather reappeared, trailed by Andie and Bobbi. And if seeing Heather stoked illicit thoughts that made him feel ashamed, Andie did even more to make him feel like a pedophile. As she came bounding down the stairs behind her sister, so small and bouncy with those little blonde braids framing her cherubic little face, with that short crop top and miniskirt on her wire-thin frame with her gentle curves in all the right places...
She’s 16, she’s 16, she’s 16 you pervert!
“Ready to go, girls?” he said calmly. Regardless of how he reacted internally to the girls, seeing them every day had given him plenty of practice at not showing it.
The girls said their goodbyes, and then Heather and Andie followed him out to the car, Andie as usual bouncing along as she went as if she didn’t have a care in the world. Andie got up front with him as he started the car, dropping her backpack on the floor and pulling her feet up onto the seat as she kept her eyes glued to her smartphone.
Kenneth fought to keep his eyes on the road, with how they kept being drawn to Andie’s legs, propped up with knees in the air, and his imagination drew up the image of those legs parting just a little ... exposing what lay under that miniskirt, behind those little panties...
He tore himself away from that, zeroing his focus ahead of him on the road.
And on the rearview mirror, where he could see Heather in the back seat.
Where he could see her stretching, thrusting her chest out, pursing those pouty little lips.
He wondered if any boys had experienced the pleasure of kissing those lips. Or had them touch any other part of his body. Like maybe even on his...
The thought came to Kenneth unbidden, but it came nonetheless. An image of Heather, naked and on her knees in front of him, those lips of hers wrapped around his pulsing manhood...
Had he always reacted this way to the girls? He thought back on it, and no, he realized, he hadn’t. He’d been married to their mother less than a year, and had dated her for two years prior to that. And he had always observed that Dana Bertrand’s daughters were very cute and feminine; he would’ve had to be blind not to notice that.
But now, living in the same house with them, seeing them every day ... it seemed the more time he spent with the girls, the more they spoke to his inner pervert.
Well, he couldn’t act out his impulses with the girls, but he certainly could with their mother. She hadn’t complained so far.
He pulled up in front of the house and the girls got out, Andie skipping and bouncing along while Heather moved at a calm and leisurely pace to the front door. Andie was the first to the door and let them in, the girls both giving a casual “Hey Mom” as they passed her in the kitchen. Kenneth found Dana standing over the stove, hard at work on the evening casserole. As usual since they’d married, she was wearing a light dress that stopped several inches above the knees and clung to her curves in all the right ways. She threw back her head of curled blonde hair and smiled at him. “Hey hon,” she said. “Hope you’re hungry.”
“Oh, believe me, I am,” he husked. He moved in and took firm hold of her from behind, molding himself to her body. She closed her eyes and hummed happily, absently continuing to stir the food as she luxuriated in the way he kissed her neck and nibbled her earlobe.
She wore no underwear beneath her dress; they’d both come to realize they liked to have little to nothing in the way of his explorations of her body. She liked to be felt as much as he liked to feel her. So when his hands cupped her breasts, with nothing but the sheer fabric of her dress to obscure the soft fleshy feel of them and the hardness of her nipples, Dana moaned aloud.
She thrust her ass back against him, feeling the hard bulge in his pants that threatened to burst out. She was suddenly tempted to let dinner burn and let him have her right now on the countertop.
But the girls...
They had taken risks before by making love on the spur of the moment at times when the girls might walk in and catch them. It wasn’t a chance she felt they ought to continue taking, as much as she may have been tempted. So she tried to temper the situation, by saying, “We’ll have time for all that later, after dinner sweetie.”
But for all Kenneth reacted, she may as well have been speaking to a deaf man. He tugged at the top of her dress, and suddenly one nipple was exposed to the air, the hot steam from the food washing over it. He brought a finger up and began tracing circles about the little hard nub. Dana’s breathing quivered, and a trickle of lubrication went running down her thigh.
She really should put a stop to this before it went any farther ... but now he was unzipping, and her skirt was being lifted up off her behind. “Kenneth ... we shouldn’t ... the girls...”
“Are upstairs,” were the last things he said before she felt him slip inside her.
Dana braced herself against the stove, completely forgetting about her ministrations with dinner, focused now entirely on trying not to make too much noise.
Kenneth breathed through his teeth, gripping Dana hard about the waist. He fought hard to keep the image of the girls out of his head, and focus only on his wife. It was fortunate that he had her to let out the feelings the girls kept stirring in him, but it would be so much less problematic if he could just keep a lid on his lust long enough to wait until they were somewhere private.
But he was apparently too much of a pervert. Just a few minutes in close proximity to the girls, and he had to get off immediately.
Well, at least the girls were upstairs and blissfully unaware of how he was ravaging their mother. At least, that was what he thought.
Unfortunately, he was wrong.
Andie was standing just around the corner of the doorway to the kitchen, watching with fascination as her mother received her step-dad’s pounding from behind. One of her hands slipped up under her top to feel her little breasts, and found her nipples rock hard. Her other hand rubbed against her crotch through her skirt, causing her to squeeze her legs together around her fingers and thrust her ass back against the wall.
People tended to write Andie off as flaky and oblivious, as if she was too lost in her own world to notice what was going on around her. But she noticed more than people gave her credit for. She had certainly noticed something was up with Bobbi this afternoon, when she had come into her room all flushed and panting; Andie had let herself seem distracted, but she definitely noticed the pair of clean panties Bobbi had grabbed before disappearing again.
And she had long since noticed the way Kenneth tended to look at her and her sister. Not to mention the things he tended to do to Mom after he got that look. And when she’d seen him getting that look in the car just now, she’d known she just had to see what he and Mom would get up to. Because it never failed to excite her when she did.
Andie breathed hard, hearing the pleasured grunts that her mom was trying hard to muffle. What must it be like, she wondered? What would it be like to be on the receiving end of that? Curiosity and excitement had often made her consider letting Kenneth do to her what she could tell he wanted to. Mom seemed to enjoy it, and she didn’t doubt she would too. But the thought of betraying Mom like that had kept her in check.
So how could she get to experience it for herself?
Well, she had one idea in mind. Her attempts hadn’t worked so far, but maybe if she kept at it...
It had been a few months since the idea had first formed in her head. It was one morning when they had been running late for school and both girls had wanted to get their morning shower in, and Heather had been taking too long to finish hers. Not wanting to wait, Andie had decided the hell with it and gotten into the shower right along with her sister. Despite Heather’s initial protests, Heather had conceded they didn’t have time and had just gone with it—which had led Andie to the realization that Heather was really hot when naked and being pressed up against her like that was terribly exciting. If they could just take it a few steps further...
Andie turned and headed upstairs to her room. She shut the door behind her, and immediately began skinning off her clothes. She dropped them all by her feet, pausing a moment to enjoy the feeling of cool air on her naked body, and then turned to the door to the bathroom that connected her room to Heather’s.
She passed through that bathroom, carefully inching open the door to Heather’s room. She saw Heather seated on her hip on the bed, her eyes glued to her phone. Andie leaned against the door jam, thrusting her hip out, and purred, “Heeeaaatheeerrr...”
Heather glanced up, and at the sight of her naked sister posed sexy in the doorway, immediately turned her gaze downward, shielding her eyes. “Oh, god, not this again!”
“You want to know what I just saw?” Andie husked, beginning to stride over to Heather’s bed. “I just saw Kenneth giving it to Mom right in the kitchen! Right over the stove, while she was in the middle of cooking dinner!”
“Sounds like dinner’s gonna burn,” Heather said dryly.
Andie climbed onto Heather’s bed, moving toward her sister like a hungry predator. “He gets me so hot! I love seeing what he does to Mom, and how Mom loves it so much...”
Heather scurried away from her sister. “Andie, would you cut this out please! It’s not going to happen! We’re sisters! Sisters don’t have sex!” These were the same words she’d said every time Andie had come onto her.
And Andie replied in her usual way too: “Who says? Who makes up these stupid rules? I got a pussy, you got one, they’re no different from anyone else’s, right?”
Andie got up on her knees and cupped her little breasts, squeezing her puffy nipples. Heather stared at her, forgetting to blink. She watched transfixed as her sister ran one hand down the smoothness of her belly, coming to the little landing strip between her legs.
Heather was forced to suppress a shuddering breath. She squeezed her legs shut, feeling a small bit of lubrication forming. “Andie, please!” she said, trying to sound firm, but her voice shaking slightly.
Andie sighed. As much as she would like to crawl atop her sister and try to physically change her mind, she knew better than to try to force things. Eventually, she hoped, Heather might give in and let her have what she wanted.
Andie got up and turned back to the bathroom door to return to her room. Heather stared after her as she went, taking in the sight of her little sister’s naked flesh and her perky little butt. She waited until the door shut behind her to unfasten her shorts and reach a hand inside them.
Andie didn’t own a vibrator per say; after all, who would ever sell one to a girl her age? But she had found ways to get around that. It hadn’t taken much to figure out that her electric toothbrush was a more than effective tool to use on her clit. And passing by where it was mounted now, she knew she needed it.
A part of her wondered if Heather was really the best candidate to be pursuing for what she wanted. Would Heather ever be able to get around that pesky incest label? Andie personally didn’t think it was any big deal, but Heather was clearly hung up on it. The truth was, Andie was also really interested in fooling around with Bobbi. The trouble was that she didn’t know how Bobbi would react, and if things went badly, Andie might lose her best friend. But Heather would always be her sister, no matter what.
Well ... all she could do was keep trying. Maybe one day Heather would cave. Maybe she could entice Bobbi into making a first move. Maybe, maybe, maybe. For now, all she could do was imagine, as she fell back onto her bed and switched her vibrating toothbrush on, bringing it down to her waiting clit.
Brushing her teeth was going to taste interesting tonight.
Rick returned home that night with little fanfare. He came in the door, and gave a brief, “Hello everyone.” Marcus, who was relaxing on the family room couch scrolling his phone, was the only one to respond with a short, “Hey,” without looking up.
Paula, who was in the living room watching TV, stood up and craned her neck to see him when Rick came in and said, “Dad, will you tell Bobbi to stop being a little pervert?”
“I’m not a pervert!” Bobbi’s voice whined from upstairs.
“What happened?” Rick asked, his brow furrowing.
Paula walked more fully into the entryway to say, “She was spying on Marcus and Raven. Doing stuff.” She imagined that her father didn’t want the intimate details of what Marcus and Raven were doing, because she didn’t want to know them herself, beyond what little glimpse she’d gotten already.
Marcus only now looked away from his phone and frowned in annoyance at Paula. “Do you have to share everything with our parents?” he sighed, embarrassed.
“Bobbi, respect your brother’s privacy,” Rick said shortly before heading into his study to set down his briefcase.
“What, that’s it?” Paula gaped, starting to get up from where she sat.
“Just let it go, Paula,” Marcus said. “The kid’s just curious.”
“Don’t call me a kid!” Bobbi whined some more from upstairs.
By the time Keiko came home a while later, Raven had joined Marcus in the family room with the apple tarts she had just made and was sharing them with Marcus, having set another one in the living room in front of Paula. She hadn’t touched it yet.
“Mom,” Paula said, trying again, “will you tell Bobbi to stop being a little pervert?”
“Oh, for god’s sake,” Marcus groaned.
