Nesting Instinct

Chapter 2: A Question of Interest

You would think a promotion would be a good thing: more money, more prestige, better support for Jade’s three daughters at home. But such an opportunity, it turns out, is not without its drawbacks. A higher position means longer hours, and longer hours mean less time spent at home.

It’s clear to Amelia that Bridget is suffering without her wife’s presence. She’s more and more irritable lately, often disappearing for long periods of time into their room with the door closed behind her. Of course, this irritation may also have something to do with her guilt and frustration over Amelia and her voyeuristic habits. If so, however, she’s not doing a very good job of avoiding her stepdaughter’s lasciviousness.

Amelia has taken to checking in on the feed of her hidden webcam as soon as she gets home each day; it’s not uncommon for her to find her stepmother closed up alone in her bedroom, fingering herself and stroking her cock at the same time as she compensates for the lack of her wife’s presence.

Amelia bides her time; she doesn’t want to push her luck with Bridget too soon after their first sexual encounter. But her mother’s absence is promising; the more frustrated Bridget gets, the more likely she is to fall back into Amelia’s arms, or so she hopes. So she lets it go a few weeks, trying to maximize her stepmother’s horniness.

The beginning of a long conference seems like the perfect opportunity to make her move. Her mother will be out of town for a week, leaving Bridget lonely and bereft. They’ve also not had much sex leading up to it due to her mother’s stress levels: Amelia knows this from having checked her camera feed. So when Bridget comes home from work the second day after her mom’s departure and heads immediately for the bedroom without even bothering to drop off her jacket at the door, Amelia decides that now is the time.

As she did the last time, Amelia removes her clothes and tiptoes out her door. She has to be more careful this time around; her sisters are home, and she doesn’t want to have to answer awkward questions about why she’s roaming the house naked.

When she reaches Bridget’s bedroom door, however, she discovers that someone else beat her to the punch.

A disheveled figure sits beside the cracked-open door of Bridget’s bedroom, peering through, legs folded daintily to one side: her middle sister, Ava. She is mostly dressed in her school uniform, but it is open wide at the throat, and she appears to be entirely without underwear.

Ava takes after their mother, much like Amelia herself does, all long dark hair, pale skin, and delicious curves. In one way, however, Ava outshines them all: Amelia considers herself fairly well-endowed in terms of breasts—each one a generous, plump handful—but she has nothing on Ava, who is already an F cup at the age of fifteen. She’s definitely going to have back problems once she’s fully grown, their mother is always saying ruefully. Amelia would be jealous, but the fact that her sister has these particular assets and not her means she’s free to admire them without any of the effort of dealing with them. So she’s not exactly losing out.

There’s another way in which Ava is notably different from the rest of the family, and she has it out now, stroking it as she peers through the crack in the door. Ava’s cock is nowhere near the size of Bridget’s massive phallus, but it’s no slouch either. Amelia has had less opportunity to admire this aspect of her sister, especially not in its current form—erect and enveloped by delicate, nimble fingers.

Amelia stops, astonished, outside her doorway, staring at this new and delicious sight. Her brain immediately kicks into gear, re-evaluating the situation. Perhaps she can gain even more from this situation than she first thought.

She tiptoes delicately towards her parents’ bedroom. Ava’s attention is far too distracted to notice her; as Amelia gets closer she can hear the heavy pants of her sister’s breathing, focus rapt on the cracked door, trying to stay quiet as she strokes herself.

In fact, Ava doesn’t notice Amelia at all until Amelia’s hand covers her mouth to keep her from crying out. Moments later, her other hand comes around Ava’s side and joins her sister in stroking the girl’s cock with long, leisurely pulls. Her bare breasts press up against the back of Ava’s shirt, lips curled by her ear in a devious and delighted smile.

“Hello sister,” she whispers as Ava’s body jolts to startled attention. She makes sure her mouth ever-so-lightly brushes the shell of her sister’s ear as she speaks. “I see you’re enjoying our stepmother’s performance as well, hmm? Isn’t it just lovely to watch?” She takes Ava’s hand firmly in her own, guiding it to resume the strokes that had stopped with her sudden appearance. “I know just how you feel.”

Ava whimpers slightly behind her hand. “Mimi?” She asks, breathless. A nickname only her sisters call her.

“Shhh,” Amelia comforts. “You have to be quiet, or she’ll hear us. You don’t want that, do you?”

The hand that was covering Ava’s mouth begins to drift down her body, caressing the arched line of her neck. The white top of Ava's private school uniform is rumpled, buttons open down most of the front, with no bra beneath. Amelia slides her hand along the exposed collarbone and delves down into the gaping neckline of the shirt, seeking out one of her enormous breasts and squeezing it firmly in hand.

“Or maybe you do,” she murmurs wickedly. “Maybe you want her to hear us, and come to see what you’ve been doing, hmm? Do you want her to know what a dirty little girl you are, sitting here fantasizing about her? Do you want her to take you into the room and punish you, slide her big old cock up inside you? Take you without mercy? Hmm, I wonder what that would feel like...”

As she’s been speaking, Amelia’s hand has continued to wander down Ava’s side, over the curve of her hip and down under her skirt. As Amelia suspected, she is wearing nothing underneath. As she teases her sister with her words, Amelia deftly slides two fingers up into her; she is already copiously leaking from her earlier voyeuristic attention.

Ava gasps as she’s entered, and slaps her free hand up over her own mouth to swallow the sound. Amelia grins and nips lightly at the very edge of her ear, prompting another small sound.

“How long do you think you can keep quiet?” she says, mocking. “A pretty thing like you? I bet Bridget would love burying her cock in your cute little hole. Or better yet, what about fucking her cock between your breasts, hmm? A huge canyon like that would be plenty even for a monster cock like hers. Doesn’t that sound nice?”

She continues her ministrations, pushing her fingers deeper into her sister’s weeping orifice, thrusting them with each stroke of her hand. “A beautiful, ripe little thing like you? Oh, she’d eat you right up. You’ve got a body anyone would love to fuck. I’m sure she’s noticed. Why not go make her an offer? I’m sure she’d be happy to help teach you how to use your equipment.”

As she says this, she jams two more fingers in alongside the first pair and rams them as deep as she can into her sister. Ava’s squeal escapes from behind her muffling hand as her body jerks with the penetration. Amelia follows up this success with a series of sudden, intense thrusts, milking her body from both ends. “Oh yeah,” she moans into Ava’s ear. “That’s how you like it, huh? You wanna be taken rough? Is that it? You can’t get enough of imagining Bridget’s fat cock inside you?”

Suddenly, as though summoned, the bedroom door swings open. The nude figure of Bridget towers over the two sisters, looking down at them, face dark and scowling. “What the hell is going on here?!” she hisses.

Amelia can practically feel the heat of her sister’s blushing face beside her as she goes scarlet with embarrassment, but Amelia herself remains calm. She takes her hand out of her sister’s cunt and lifts it up to Ava's mouth, slipping the wet fingers inside and forcing her to taste herself. With one hand on her sister’s face and the other on her cock, she leans back, forcing her to arc and exposing the long and luscious lines of Ava’s body for Bridget to see.

“Don’t mind us,” Amelia says with false sweetness. “Ava was just getting herself a little bit of an education. She’s shy, you see, so she didn’t want to come right out and ask you, but she’d just love it if you could teach her to use that adorable little cock of hers.”

“Get the fuck out of here,” Bridget snaps, impatient. She meets Amelia’s gaze with a cold fury. But Amelia is unintimidated.

“Oh, don’t be like that,” she cajoles, voice syrupy. “You’re the only role model she has! Who else is she going to learn it from, hmm?” She strokes Ava’s cock with an extra firm grip, drawing another embarrassed moan from her sister.

“Besides,” Amelia continues, “what other options are there? I guess I could ask Mom about it, hmm? Maybe she’d be curious to know what you are and aren’t willing to do with her daughters?” She raises a pointed eyebrow at Bridget, who freezes in shock.

Amelia smiles. “That’s what I thought.” She takes advantage of Bridget’s momentary paralysis to stand—dragging her sister up with her—and flounce into the bedroom. She drags Ava over to the bed and then lies down herself, draping herself across the pillows and spreading her legs cheekily. “Let’s all just be one big happy family, hm?” she says.

Ava’s gaze darts back and forth between her sister and her stepmother, clearly conflicted. If she understands what Amelia is threatening Bridget with, she makes no indication. Instead she looks shyly down at the bedspread. “Umm, I... I actually wouldn’t mind if... I mean... I did have... some questions...” she mutters, barely audible.

The sigh from Bridget is the deepest, weariest sound Amelia has ever heard. For a moment she thinks her stepmother is still going to throw them out, and Amelia will have to figure out how serious she actually is about following through with her threats. But then she straightens her shoulders and firmly, deliberately closes the door. Amelia grins.

Bridget turns around and makes a gesture towards Ava. “Get between her legs,” she instructs. Ava hurries to follow her command, crawling up to Amelia on her hands and knees.

Bridget mounts the bed behind Ava and reaches around either side of her, grabbing Amelia’s ankles. With careless ease, she lifts them up and pushes forward, bending Amelia backward and pressing her down until she can hook those same ankles over Ava’s shoulders. “Hold these up,” she instructs. Ava reaches up and grabs onto Amelia’s shins.

“Now,” says Bridget, “like this.” With that, she lets go of Amelia’s legs and reaches around Ava to grab her dick. With a gentle grip, she guides it to Amelia’s entrance. Amelia herself is already dripping with want; she feels like she’s practically drooling with it as well.

Bridget lines up her two stepdaughters and then pushes forward lightly, causing the head of Ava’s cock to begin to breach her sister. Amelia moans with enthusiasm as Ava enters her, curling her ankles to encourage her forward.

The slow, inexorable pressure does not cease. Bridget’s hand on her stepdaughter’s back slowly pushes her further and further forward. She lets go of Ava’s cock as it slides deeper inside, to make room for her to go further, sinking inch by inch into the warm, welcoming cavern. Ava whimpers as she slides deeper and deeper and finally bottoms out in her sister’s hole, flesh to flesh against the back of her thighs.

“Ooo,” Amelia moans, encouraging, “yeah, just like that. That feels so good, Ava.”

She grins up over Ava’s shoulder at Bridget. With her hands she reaches around either side of her sister, grabbing her thighs and the bottom of her buttocks and pulling them apart to reveal her dripping pussy. “Now,” she instructs, “why don’t you help set a rhythm for her, huh? Really show her how to do it?”

Bridget growls, and moments later Ava lets out a high-pitched squeal as her stepmother enters her from behind, jamming her much larger cock into Ava’s exposed hole in a single deep sheathing motion. A second after that she begins thrusting, long and leisurely and deep, forcing her entire member into Ava’s virgin entrance over and over, and through her forcing Ava’s own cock into her older sister just as deep.

The two girls whimper and moan as Bridget sets the pace, ramming them into each other in tandem with her own fucking. Amelia watches with pleasure as Ava’s face pinches with the overwhelming feeling of being drilled deep again and again by such a massive cock. She remembers the feeling herself fondly.

“Nice, isn’t it?” she says to her sister, who is clearly too overwhelmed to respond.

And so they continue like that for some time. Bridget, arms braced on the bed on either side of her stepdaughters, fucks Ava deep and hard from behind. The motion forces Ava equally deep into Amelia, ankles on her younger sister’s shoulders, dick disappearing completely as she embeds the entire length over and over in Amelia’s pussy.

Amelia wishes it could go on forever, enjoying the feeling of both of them plugging her, even though it’s vicarious on Bridget’s part. But Ava is, after all, somewhat inexperienced. And there’s only so long one can hold out against the sort of intense ramming that Bridget is giving her pussy. After roughly fifteen minutes or so, Amelia feels Ava convulse and shudder over her. Strangely, however, she doesn’t feel her coming. She blinks up at her sister, but Ava also looks confused.

When Ava’s shaking subsides, Bridget pulls out of her, still hard. With one large but gentle finger, she traces the edge of Ava’s shuddering hole. Ava herself has stopped thrusting, still buried deep inside Amelia.

“I find it happens that way a lot,” says Bridget, and her voice is surprisingly soft and warm. For Ava at least, it appears, she holds no malice. “It’s pretty common to come with your vagina without coming with your penis. Usually that’s not true the other way around though; coming with your penis triggers an orgasm for both.” She smiles for her stepdaughter. “Let’s see if we can’t get you the other half of yours. Switch places with your sister.”

Ava pulls out, and Bridget directs them to new positions, with Ava laying on her back on the bed this time and Amelia facing her, straddling her lap. With little care for Amelia’s comfort, Bridget drops her back down onto the spike of her sister’s cock. Both girls gasp at the sudden return of the penetration.

Amelia smirks, trying to hide the fact that she’s slightly winded. “I guess Ava likes your cock better than my cunt,” she says, teasing. “You gonna satisfy her again with that monster?”

“Now,” says Bridget from behind Amelia, ignoring her words entirely, “I think your sister’s been a little bossy, don’t you? I think maybe she needs to learn a lesson about her place.”

Behind her, Amelia feels Bridget’s hands on her buttocks. Her eyes widen. “No- wait-!” is all she can get out before her stepmother’s slicked-up cock returns, this time pushing into a very different orifice.

Amelia moans in a mix of pleasure and pain as Bridget begins to slowly push her monstrous cock up her ass. The head breaches the tight ring of muscle at the entrance and proceeds to inch its way up inside her, bit by bit. “Not there,” she groans, but there’s nothing she can do about it. Bridget keeps forcing her way forward, cleaving her wider and wider open as she stuffs her ass full of cock. It goes on longer than Amelia ever thought possible. Ava groans as the second penetration of Amelia’s holes tightens her pussy around Ava’s own cock, strangling it.

It must be a full minute later that Bridget finally bottoms out in Amelia’s ass, her entire massive spear of meat well and truly stuffed into the strained orifice. Amelia can feel it inside her when she swallows. Then, before she can even get her bearings, Bridget grunts, “Follow my lead,” to Ava and begins to move.

Amelia feels the wind knocked out of her as the two women begin to fuck her, simultaneously filling both her holes over and over. She chokes on the sensation as the thrusts speed up until they’re ramming her in earnest, driving into her again and again and again.

“Ah!” Ava moans, “it’s so good! It’s so tight!”

Bridget leans down behind Amelia to whisper in her ear. “How do you like that?” she mutters, too softly for Ava to hear. Amelia takes it as the rebuke it is, unable to do anything but hold on as she’s sandwiched between her two family members, speared by them both.

And hold on she does, clinging for dear life to her sanity as they proceed to fuck her brains out. The two women drive her so hard she sees stars, so hard she’s worried she’ll black out. Ava’s cock is warm and filling and satisfying, while Bridget’s is massive and painful and punitive as it distends her anus. She’s never felt so full in her entire life.

They fuck her just as long in this configuration as the previous—longer, even. Amelia loses track of time as her holes are filled again and again, thick rods pumping in and out of her in time with each other.

Finally, finally, she feels Ava start to come in her, seed flooding into her in helpless spurts as her sister is wracked with pleasure. She stills as she pumps her cum into her sister, her body arcing underneath Amelia.

As her cock softens, it slips out of Amelia’s hole and falls underneath her, rubbing at her clit. Amelia whimpers in pleasure. Bridget’s thrusts redouble in speed, slamming into her at a brutal clip, ramming all the way home with each thrusts, deep into her ass. Each movement rubs her clit against her sister’s soft cock, until Amelia too is mewling and helpless with pleasure.

When she comes, the convulsions of her passages tip Bridget over the edge, and she feels her stepmother’s seed flood into her, filling her backside with jizz. She wrenches Amelia down onto her cock as hard as she can as she comes, slamming her down one last time in order to unload as deep in her as possible. When she finally finishes and withdraws her softening cock, she leaves Amelia’s asshole distended and raw and fucked-wide, twitching in the open air.

When Amelia finally stops seeing stars, she finds Bridget seated next to Ava, stroking her hair. She kisses her stepdaughter lightly on the head. “Was that okay?” she asks gently.

“Yeah!” Ava says enthusiastically. “It was really good! Can we...” She blushes once again. “I would be okay doing it again sometime. Umm... if it’s okay...”

Amelia can see Bridget glancing at her from the corner of her eye. Her stepmother’s expression is unreadable. “I guess we’ll have to see how your sister feels about it,” she says.
