Chapter 39: To the Limit

Kenneth didn’t know how much longer he could pretend he didn’t feel like a raw nerve.

It had been hard enough trying to ignore how Heather and Andie pushed his buttons even before he’d known they were sexually active. Now it was like the more he looked, the more there was to tempt him. Like the way Heather would flaunt herself for Zander whenever Kenneth saw her with him, pressing her boobs into Zander’s chest and thrusting her ass out while she threw her arms around his neck and looked at him with the textbook definition of bedroom eyes. Or the way Andie would scamper into a room in clothes that pushed the boundaries of modesty while Heather was watching TV and happily throw herself across her sister’s lap, and the two girls would affectionately caress each other’s skin while they watched, somehow managing to look both innocent and oh so provocative at the same time.

And that didn’t even cover the number of times he’d heard those noises coming from the girls’ bedrooms. It was beginning to feel like they were practically daring him to stop and listen to their erotic moans as they pleasured each other, with how often and how loudly they were doing it.

The most bewildering thing about all this was Dana’s reaction to it all. Or more specifically, her lack of one. It was genuinely bizarre how Dana appeared to be going about life in blissful ignorance of her daughters’ burgeoning sexuality when it seemed that Kenneth couldn’t go up or down the stairs without catching the sounds of the girls going down on each other from behind a closed door. It was like she had some kind of blinders on where her girls were concerned.

But Dana could most certainly see that something was bothering Kenneth. She had been constantly asking him lately why he seemed so tense, and Kenneth was running out of excuses. He could only keep feeding her stories about last minute rewrites to his building contracts or being in danger of losing a deal so many times. The last thing he needed was to admit to his wife that he was struggling to suppress lustful feelings toward her daughters, and that they were only making it progressively harder. And as much as she appeared to enjoy the way he was venting his lusts on her—as in she really, really enjoyed it!—that was a stopgap measure at best.

It had become clear to him a few weeks ago that something was going to have to give sooner rather than later. And the Saturday after Heather’s graduation was when that finally happened.

It was while Dana was out for her morning jog, and Kenneth was seeing to a little straightening up in the living room. He had just reorganized the magazines on the table and then turned and pulled the rumpled loveseat cushions straight, when something peeked out between a couple of the cushions. He stared with a furrowed brow for a second at the little hint of pink poking out amidst the brown cushions, and cautiously reached out a hand to retrieve whatever it was...

Kenneth’s heart jumped into his throat when he found himself holding a pair of panties. And based on the faintly visible flower imprints on them, he was reasonably sure they belonged to Andie.

Oh dear God, the implications. The idea of what the girls must have been doing out here in the living room, right here on the loveseat no less, had him instantly hard as a rail. He fought not to imagine the scenario that would have led to Andie leaving her panties here and forgetting to retrieve them, and determined it was best that he simply return them to their owner before Dana came home and found them.

It was only when he was on the first few stairs heading up to Andie’s room that he began to imagine the awkward scenario that would ensue if he found Andie in her room and had to return her panties to her personally. Even if he tried to avoid asking questions, she no doubt would try to offer some kind of explanation that he really, really didn’t think he ought to know. But thankfully, while Heather’s door was closed and her room most likely occupied, the door to Andie’s room was open and she was not inside when he looked in. He could slip in, drop them in her hamper, and slip out with no one the wiser.

At least, that was the idea in theory.

It worked fine until he got to the slipping out part. He had just dropped the panties in her hamper and was about make his quick exit when a soft, feminine moan caught his ears. He turned in the direction of the sound, finding himself looking at the open door to the adjoining bathroom between Andie’s and Heather’s bedrooms. Not a closed door this time, but an open one. And as much as Kenneth knew he should be listening to the angel on one shoulder telling him to walk away, Kenneth found himself instead obeying the devil on his other shoulder and approaching.

“Oooooohhh, yeah!” he heard coming from the open door on the other end of the bathroom to Heather’s room. Since the girls weren’t right in the bathroom and he hadn’t actually seen them yet, he still had a chance to do the right thing and leave. But the more he heard Andie’s voice crying, “Oooh, right there! Ahhh! Yes!” the harder it got to act on that notion. The temptation to keep approaching was just too powerful.

And so it was that Kenneth found himself peering around that open door and peeking into Heather’s room, to find both his stepdaughters gloriously, beautifully naked on Heather’s bed, staring at Heather’s ripe, peachy ass as she knelt between her sister’s legs and hungrily devoured her sister’s pussy. Andie looked like a pervert’s dream come true as he stared at her adorable teenage face, with her eyes closed and her mouth hanging open, and her little breasts capped with very erect pink nipples that her little hands were squeezing and that Kenneth knew he’d give anything to get his mouth on. And the unbearably erotic noises Andie was making ... good God!

Kenneth was not conscious of opening his fly, but the next thing he knew, his dick was most definitely out, and he was most definitely wanking it. And with that awareness also came the realization that he should stop, that he should put his dick away, leave this room, and stop watching his agonizingly sexy teenage stepdaughter writhing in pleasure on her sister’s tongue.

He should. He really, really should.

“Mmm, yes, Heather!”

And ... he was going to.

...

Any minute now.

“Aahh, fuck!”

Like, now.

...

Okay, now.

“Oh, right there!”

Fuck, why did the girls have to be so hot?

“Ooh, I’m gonna cum!” Andie whimpered, digging her fingers into Heather’s hair and arching her back up off the bed, thrusting her little breasts in the air in a way that made Kenneth’s breath catch in his throat. He bent at the knees and struggled not to make a strangled gasping noise, though with the way Andie screamed at that moment he doubted it would have made a difference.

Heather finally deigned to say something, lifting her head from between Andie’s legs and putting a hand to her sister’s mouth. “Hey, quiet, Kenneth’s still home!”

Well, at least they remembered that at some point. It might have been good of them to remember that before they’d forgotten that Andie’s bedroom door was still open, and that the open bathroom connected their rooms.

Or maybe before Andie’s head turned to meet Kenneth’s eyes, clearly seeing him watching them, clearly seeing his dick in his hand.

Kenneth jerked back, fumbling to stuff himself back into his pants, anticipating the inevitable scream. Which, it turned out, didn’t come. But Kenneth was too panicked to register that Andie was not freaking out, but in fact smiling at him. He clumsily made himself as close to decent as he could and retreated back the way he’d come as quickly as he could.

Even as Kenneth ducked into the sanctuary of his bedroom, he knew it was too late. He was already in big trouble. He could only imagine what the fallout of this would be. Would the girls rat him out to their mother?

... No, that would mean admitting to their mother what he’d been watching them doing. Perhaps their own need for self-preservation would translate into his own. As far as he could see, it was his only hope.

“Enjoy the show?” a girl’s voice purred.

Kenneth whirled around to find Andie standing in his doorway, wearing a bathrobe that she was merely holding shut, not having tied the belt, and looking at him with an expression that screamed of mischief. “Andie, what are you doing?”

“I’m asking if you enjoyed the show,” she repeated, taking a few steps into the room.

“Andie, you should go back to your room,” Kenneth said even as he started backing away. “Put some clothes on. And be more careful about keeping your door shut!”

“But don’t you want to see us like that?” Andie purred. And then she was slowly pulling her robe open. “Don’t you think I’m sexy?”

Kenneth was frozen, standing there, staring at his teenage stepdaughter displaying her naked front to his gaze, openly inviting him to look. “Andie...” he stammered, struggling to come up with something to say, trying to ignore the throbbing erection in his pants.

“It’s okay,” Andie said, continuing to approach him, and now letting her robe slip off completely. “I don’t mind if you look. In fact...” Now she took hold of his wrist and began lifting his hand slowly in the direction of her breast. “ ... if you maybe wanted to do more than look...”

Kenneth thought he might pass out from the blood rushing to his head. She couldn’t possibly mean...?

“Andie, what are you doing?” Heather called, appearing at the door in a light camisole and a pair of short shorts. She rushed into the room, snatched up the robe and threw it over Andie before turning her to herd her sister out of the room. “Are you crazy?”

“What? It’s just Kenneth!” Andie protested in a supremely innocent voice as the girls disappeared into her room.

Kenneth basically fell into a seat on his bed. He was desperately trying to find some way of dealing with what had just happened. After all this time trying to tamp down on his feelings for his stepdaughters and ignore what they were doing together, now he had not only seen them in the act, not only had one of them caught him watching, but she had then come right up and practically thrown herself at him, giving him full permission to do exactly what he was fighting not to do. It was like someone on a strict diet had successfully found the will to walk away from the buffet table, only for the dessert to get up and follow him home.

And what really had him sweating was that he seriously doubted this would be the end of it. If Andie had offered herself to him once, she was likely to do it again. Of course, the responsible thing to do would be to march over to that girl and tell her not to do that again, but he honestly didn’t trust himself in her presence right now. And if she kept trying to seduce him, how long would it be before he gave in? He knew the limit of his own strength, and he knew it wasn’t enough to indefinitely resist a nubile teenage girl offering herself to him on a silver platter. As long as he stayed in this house, it was only a matter of time before his base desires overcame his better judgment, and he ended up doing something he wouldn’t be able to take back.

Which meant there was only one thing to do.

Kenneth was still writing the note when Dana returned home from her run. He sighed in dismay when he heard the front door close; the coward in him was hoping he’d be gone before she got back. This was going to be a lot harder if he had to look his wife in the face.
