“Mimi,” Ava whines from across the room, “I’m trying to sleep!”
Amelia glances over at her younger sister. Their aunt and uncle’s guest bedroom is a little cramped, given that it contains both a bunk bed and a separate twin bed in addition; it doesn’t give a lot of space for privacy or discretion, and the pale glow of Amelia’s phone lights up the vast majority of it despite being on the dimmest setting.
Ava is currently curled up in the bottom bunk. The young girl’s voice is muffled, blanket pulled up over her head to block out what light she can. It’s also pitched low and soft to avoid waking their youngest sister Sofia, who is fast asleep in the bed over hers.
“No way, this is too good to turn off,” Amelia hisses back from her own bed. She doesn’t spend much time looking at Ava, her eyes instead glued to her phone screen. She was annoyed at first to be fobbed off on her relatives for the weekend, but now that thought is the first thing from her mind. Knowing that she would be leaving, she had made a play the previous night to sneak back into her mother’s room and hide another small spy camera, just in case Jade and Bridget had any notable encounters while she was gone.
The result is better than she’d hoped for.
The feed is live. For some inexplicable reason, Bridget seems to have angled herself and Amelia’s mother into a position that gives the absolute best possible view of their encounter together. However that came about, Amelia is certainly not complaining. Right now she has an utterly amazing close-up view of the two women’s backsides, the perfect shot of Bridget’s cock swiveling in-and-out, in-and-out, in-and-out of her mother’s cunt as Jade rides her. She didn’t even take off Jade’s panties; the poor, maligned piece of black lingerie is stretched obscenely to one side, moved just far enough over to give Bridget’s dick access to Jade’s hole.
“Come on!” comes another hissed protest from the far corner of the room.
Amelia’s only been watching the feed for a minute or two—since she decided to properly turn in for the night—and she’s already soaking wet. “Why don’t you come over here, then?” she hisses back. “You should check this out.”
She refuses to look away from the screen to check if her sister has decided to accept or ignore her invitation, but a few moments later she feels the edge of the bed dip as Ava gets up onto it. “What the hell are you even watching?” she whispers.
Amelia reaches out and pulls Ava snugly into her side. Her sister is wearing little more than a long nightshirt, while Amelia herself always sleeps entirely in the nude. Her sister gives a little gasp of protest as she loses her balance and tips in, and then another as she looks at what’s on the video screen.
“Seriously?” she whispers. “You’re keeping me awake so you can watch porn?”
“This isn’t porn,” says Amelia. “Or,” she corrects herself, “it’s not just any porn, anyway.”
“What do you mean?” Ava squints at the screen, her eyes having trouble adjusting to the light after the darkness of the room. Then, after a moment, Amelia feels her body go rigid beside her. “Is that...?”
“Uh-huh,” Amelia says, smug. “Look at them go! Mom’s really going at it.”
Ava recoils. “You’re spying on them? That’s- that’s our mom!”
“And?” Amelia points out. She wraps her arm around Ava’s waist and drops her fingers to the girl’s lap, toying idly with her dormant cock through the fabric of her nightshirt, rousing it with a soft inhalation from her sister. “You say that like I didn’t catch you peeking at Bridget once already, she murmurs in her ear. “A little late to be worried about keeping it in the family, isn’t it? You seemed willing enough to fuck me when the situation called for it.”
Ava lets out a stifled groan, but doesn’t say anything more. Amelia takes this as permission and allows her hand to creep up her sister’s thigh, stealing under her clothing and taking her member properly in hand. She strokes it idly as she turns her attention back to the video. “Mom really loves to ride a nice thick cock. I guess I inherited that from her.”
She leans against Ava’s ear to breathe her words into it, warm and wet and quiet. “What about you, hm? You like having Bridget’s cock in you too, don’t you?”
Ava squirms and moans. Laughing, Amelia re-arranges them on the bed so that Ava is sitting in front of her, between her spread legs, allowing Amelia to wrap her arms around her sister. She holds her phone in front of them both with one hand and hooks her chin over her sister’s shoulder so they can watch together. With her other hand she continues to idly stroke her sister’s cock up and down.
Ava’s back is pressed against her breasts. She does wish her sister was naked, so she could feel the heat of skin-to-skin contact, but for now she doesn’t want to have to change position again. Instead she satisfies herself with long, deliberate strokes of Ava’s member, enjoying the soft, velvety feeling of the skin over hard flesh. Ava is trembling against her, clearly extremely turned on by watching their mother and stepmother mate in the video.
“It’s hot, right?” Amelia murmurs into her sister’s ear. She pauses for a moment in stroking her cock to idly dip her hand further down. It comes away dripping wet with her sister’s slick. With a grin, she plunges a few fingers into Ava’s shivering hole and gathers the girl’s juices up onto her fingers, bringing it back out and slathering it up onto her cock as natural lubrication. It makes her resumed pulls that much slicker, that much tighter. She can see her sister biting her lip.
Before Ava can get off, however, their mother does. On the screen, they see the close-up hips stutter and come to a halt, her nether lips twitching around the impaling spike of Bridget’s dick as she hits her orgasm. Amelia stills her hand as they both pause to watch their mother come, shaking and shivering and engulfing her wife.
When Jade finally gets up off of Bridget, they can see clearly that the other woman is still hard. Their mother doesn’t hesitate; she turns to the side, moving her face over Bridget’s crotch, and swallows her down in a clean, fluid movement. The girls have a clear, center-screen shot of the way she bobs her head up and down over their stepmother’s cock. At the same time she reaches up with her hand and inserts a pair of her fingers into the woman’s sloppy, wet hole, which even now weeps with want of her.
Jade grins against the side of her sister’s head and copies the action herself, abandoning Ava’s cock to reach down below her and slip a few fingers inside her. She sets her rhythm in time with her mother on screen, teasing her fingers in and out of Ava’s pussy.
“How’s this?” she murmurs into Ava’s ear. “You want to do it just like Mom and Bridget?”
Ava gives a little whimper. Amelia shushes her. “You’ll have to stay quiet, though.” She glances over at the bunkbeds. “Wouldn’t want to wake Sophia and let her see what I’m doing to you.” Ava’s nethers twitch around Amelia’s fingers. Amelia continues to thrust them in and out, in and out, just as her mother does.
“I-if we’re doing it just like them,” Ava whispers, her voice trembling, “then you should be going down on me too, right?”
Amelia smirks. “Oh,” she murmurs. “I guess you’re right.” She pulls herself away from Ava’s back and slinks down next to her, parallel but facing the other direction. Returning her fingers to Ava’s waiting hole, she copies her mother’s other motions as well, sliding her mouth down onto the stiff, straining spike of her sister’s erection. With her free hand she continues to hold the phone on Ava’s thighs, so they can both keep watching the show.
It’s a little hard to tell on the video feed, given the angle, but Bridget seems to be playing with both of Jade’s holes at the same time as she’s being fingered herself. As Amelia settles in to blow her sister, she feels her sister’s fingers tentatively come up behind her and begin to explore her own soft recesses. A hesitant digit pushes, first lightly and then firmly, into her pussy, sinking in deep. Amelia gives a hum of encouragement around her sister’s cock. The finger retreats, dripping wet, and then moves up to her asshole instead, poking inside there as well. She pushes it in at the same pace, and then begins to thrust it back and forth.
Amelia watches the screen, continuing to copy her mother’s pace as she simultaneously fingers and fellates her partner. Then Jade pulls her fingers back out, changes the angle of her hand, and...
Ava gasps. Amelia grins. She draws herself back up Ava’s cock long enough to tease her: “Well, if we’re going to be copying them faithfully...” Then, just as her mother did, she points her fingers, and slides her entire hand into Ava’s vagina, pushing it inside up past the wrist.
She hears Ava slap her free hand over her own mouth to keep from crying out as her sister fists her, returning to suck her cock at the same time. Her own fingers have fallen out of Amelia’s holes; instead she grips onto the flesh of one of Amelia’s buttocks like it’s a lifeline, like she might collapse without a firm hold. Amelia smirks and attacks her sister’s genitals with gusto, swallowing around her again and again and she works her forearm in and out of her wet and dripping hole, stretching it wide.
Ava gulps and squirms and whimpers. Amelia feels the shuddering convulsions of her hips as she comes around her sister’s hand, her pussy tightening around the invasion as it grips her through the throes of pleasure. Nearly at the same moment, Bridget starts to come onscreen from her other genitals; this close, they can see her balls tighten.
As Bridget’s swiftly-softening cock falls from their mother’s lips, Amelia lifts her own mouth up off of her sister’s cock with a pleased sigh. She turns to look over her shoulder and grins at Ava, arm still firmly embedded inside the girl. “Should I keep going?” she asks.
She feels Ava’s fingers convulse around her butt cheek. “Can I... You let Bridget... Could I...”
“Hm?” Amelia asks, raising an eyebrow. She gives a playful thrust of her forearm back and forth. “What? Spit it out.”
“Can I, um...” Ava’s grip on her eases, sliding around to her crack. The fingers run up the canyon until they come to rest on the hidden divot of her asshole. She gives it a tentative, suggestive little push, nudging the very tip of a digit inside the tight ring of muscle. “Can I fuck you here too?”
Amelia’s eyebrows rise. “You have gotten bold, little sister.”
Even in the dark, she can see Ava blush. “It’s fine. Forget it,” she mumbles.
Amelia considers her for a moment. Then, abruptly, she yanks her arm out of her sister’s vag. Ava gasps at the overstimulation, flesh still sensitive from her previous orgasm. Wiping her hand on the sheets, Amelia moves to straddle her sister’s legs, kneeling on the bed with her rear end pointed at Ava’s face.
Ava wastes no time. With a gasp she pulls her legs back until she can rise up onto her knees. Her cock drags up between Amelia’s thighs, rubbing up against her clit as it moves towards its destination. It finds her pussy first, to Amelia’s surprise, and slips inside, penetrating her, pushing in to the hilt.
But it doesn’t stay. Moments later she’s pulling it out again and continuing the journey, further up, until she gets to Amelia’s ass. She lines up the now-slicked head with the tight ring of muscle, and pushes-
Amelia gasps as her sister slides a hard, thick cock up her ass. She doesn’t hesitate in her motions, forcing her open with her dripping, eager spike of flesh, sinking into her in a steady, determined slide.
It’s Amelia’s turn now to struggle to stay quiet. She drops the phone onto the bed as her sister fills her up and begins to thrust. It’s nowhere near as hard and dominating as when Bridget does it. With her stepmother, it feels like a punishment; with Ava, it feels like discovery, like hesitant, fumbling exploration yielding unexpected fruit. Her sister bottoms out inside her and pulls out just a little; a few experimental thrusts that stay deep. Then she tries pulling almost all the way out again, leaving in just the head, before diving back inside her to the hilt. Then she pulls far out once more and gives a few shallow thrust, working just the head in and out of her in rapid succession. Each new movement brings something different, something new and curious.
Amelia keeps her head down and lets her sister fuck her. Leaning her weight onto one elbow, she reaches between her legs with her other hand and begins to finger her clit, feeling the sparks of pleasure. She’s dripping wet, uselessly, but she can’t quite reach all the way to penetrate herself from this position. She’ll have to make do with the sensation of fullness from her ass, the dedicated and studious attention of Ava’s thrusts as she works it open again and again.
She focuses on her own pleasure, mashing her fingers against herself good and strong, just how she likes it when she’s close. She gasps quietly when the building pleasure finally crests, tipping her over and spilling all around her, wracking her hips and thighs and torso with sudden lightning jolts of orgasm, cascading through her like electricity.
Her orgasm causes her muscles to squeeze, gripping Ava’s cock and pulling it deep inside her. Ava whimpers and comes as well, her climax wrung out of her, milked into spilling inside Amelia’s ass, helplessly filling her with cum.
When she finishes, Ava collapses across Amelia’s back. Amelia lets them both slump down, counting on the bed to support them both when her knees cannot.
Idly, she fishes up her phone from where she dropped it and checks the screen again, even as she feels Ava’s softening cock slip out of her tired, well-exercised hole. Bridget and Jade appeared to be cuddled up together, sleeping curled around each other. A very domestic sight. Amelia grins and holds it up so that Ava can see the screen.
“What do you think?” she whispers. “Should we sleep like that too?”
Ava looks hesitant. Shy.
Amelia wiggles her eyebrows. “If we wake up before everyone else, I’ll blow you again in the morning. Maybe even let you have a second go at my ass.”
She feels her sister’s hand slide almost possessively up her thigh, coming up around behind her to part her ass cheeks and idly play around with the juices that are already beginning to leak out of her hole, mixing them with the generous gushing slick of her orgasm. “Aren’t you worried about getting caught?” she mumbles.
Amelia snorts. “I know how to cover my tracks.” She once again glances over to where Sofia is still sleeping. There’s no sign of movement; the girl is still dead asleep.
Ava’s finger pushes lightly into her sister’s vagina, still exploring. “Okay,” she says shyly.
Amelia grins wickedly in the dark.
