Toys and Noise

It didn’t take long before Lily began to hear more feral sounds than ever before seeping through the paper thin walls from her big sister’s bedroom next door. It was never a plan, Lil giving Emily the packaged new toy she’d yet to use, but when the thought occurred, there was no question or hesitation. Lil knew that it would open up her sister’s back door for her own pleasure, and if other things fell into filthy place well enough, it might be the door Lily could use to take her big sis to the sexual moon and back a few times, and seal their secret taboo dance.

The masturbation soundtrack began with the usual half-muffled sighs and soft grunts as Emily fingered herself, and even during that early ramp-up, Lily kept wondering if their recent naked embraces and shared kisses were the cause of Em’s newly-heated needs. God, Lily was fucking hoping that was what was stirring her sister’s stewing pot. Then Lily heard the telltale whimper of a first time anal toy user as the slim head popped into that tight, barely played-with pucker. Then came the soft hum and the added fingers. Lily knew the wriggling button had yet to be hit or there would be uncontrollable audible moaning. Lily had already burnt one of these toys out herself, so she knew the hot bliss first hand.

When Lily heard Em start to use grunted obscenities, she knew it was time to go and participate, but she could barely stop herself from shoving half of her fist in between her thighs for her own pleasuring. Lily finally got up, tiptoed nude to her sister’s door and gently nudged it open, then leaned back to watch, one hand tugging at her own nipples, the other digging into her soaking pussy’s slit. Both girls began to emote lewd sounds in synchronous harmony until it registered in Emily’s ears that she could actually hear her younger sister matching her own vocal rhythms. Emily opened her eyes and tried to stop the vulgar motion in her ass and her levitating hips as she too dug into her pussy’s moaning purse. But she was too steeply into the climb to stop willingly, and before another second passed, Lily cried out, “Don’t stop!”

The girls locked eyes. Lily was on fire and loving every crackling second of this daredevil invasion. Emily was stunned that she was not only giving in to her carnal vulnerability, but also feeling a lightning bolt of heightened lust run through her every nerve ending with her younger sister’s matching play and hungry naked presence.

Lily, with a deeply aroused whimper said, “Hit the wriggle button, Em”. But she could see that Emily had no will left to stop and look for it. That was another gift of a cue to ravenous little sis.

"Lemme help", Lily said, and she knelt next to the vibrating Emily. Lil whispered, "Let me show you….", as her hand met her sister’s in the warm wash of Emily’s swollen, sopping cunt lips. Lily took the vibe’s end, and softly said, "The wiggle button is just above the on switch. Here."  Sshe flipped it on. The vibe began to wiggle deep into Emily ass and Lily gave it a well-studied slip and slide and twist ride, spelunking into her sister’s gasping bottom’s hole. Emily was so startled that her hips were halfway to the ceiling and her eyes were tearing up with overload. 

"Too Much. Stop. Please!" cried Em. And like a good sister, Lily eased off the wriggle, and let the vibe just buzz in place inside of Emily anal canal.

"It is pretty intense the first time. Probably should work up to that. But you see what I mean, Em?"

Emily was hovering in orgasmic limbo and could barely speak.

Lily smiled and just said “It’s better like this.” Show and tell was over. It was time to dive in.

Though Emily remained in a state of semi-disbelief, she was too far gone to do anything but surrender to the moment. And to the queen.

Before she knew it, her baby sister was sucking her nipples, and gently using the ass vibe as a slow moving thin cock, slipping and sliding it in and out of her depths, tip to hilt, in a wickedly promising tease.

Both of Em’s nipples were soon sucked to tender diamond hardness, and Lily’s lips were making a path southward with no apologies. She kissed Emily’s sopping lower slit and sucked her juices in with intended slurping sounds. Then she raised her head up and waited for Emily to look down.

"Let me show you how girls eat pussy." Again, Emily was unable to form thoughts, much less the words to express them.

Lily had her prize in hand and mouth, and wasted no time in diving in and using every dirty trick in the book to take her sister to the edge and back more times than Emily had ever skirted an edge with another. Lily’s right hand played ass-fuck with the vibe, sometimes shutting the buzz off, and other times hitting it to match something her tongue was doing to Emily’s thumping clit, while her fingers played come-hither on Em’s g-spot and pubic bone.

Emily had lost all resistance and was clawing at anything she could reach, including her little sister’s thick, dark mane. Lily knew she had sealed the deal when she felt Em’s hand fisting her hair and pushing her face deeper into big sister’s twitching drenched abyss.

Lily stopped her tongue lashing on her sister’s pussy just long enough to growl, “Cum for me, Em, and don’t try to stop, cuz I’m not gonna let you stop.”

Lily started fucking Emily’s ass with the toy, devouring and shoving however many fingers she could into her sis’s sweet cunt, then just before the leap, Lily turned the wriggle button on and the toy started it’s snake dance, fathoms deep inside Emily’s rear canal.

There was an orgasmic roar from Emily that neither of the girls had ever heard before, and Lily went to work making sure that the screaming flight didn’t end until her sister had hit a few dozen peaks along the way.

Emily wailed and spasmed and rocked and peaked again and again, until Lily felt the perfect let up point, and began to ease her novice sister back down to earth. Her devouring turned to soft kisses, she let the vibe stop and slip fully out of Em’s rear, but she made some long lapping licks from anus to clit to tease Emily, then turned Em to face down, then took a moment to shove her tongue into Emily’s ass and wriggle it about to mirror the toy’s earlier movement. Emily just arched like a cat in heat and growled into her pillow. Lily stopped and purred, “Yeah, I love that too. Hence, the flavored lube.”

After the First Collision

Lily crawled upward and wrapped her arms about her big sister, who was still shaking and twitching from the roll of orgasms she’d just been launched through. Lily caressed Em’s hair and whispered sweetly, “I love the way you taste. The way you cum. You are so fucking beautiful, Em.”

Emily just held tight and tried not to think of that repetitive phrase rushing through her weakened mind “But you’re my sister….”. She could think it, but somehow the words didn’t come.

"Em, thank you for letting your little sis show you, teach you. it’s late. We should maybe shower off the sex and crawl in together. I wanna sleep with you tonight, ‘kay?" Emily shook her head yes.

"Good. C’mon hot stuff." And the girls began to giggle when Emily tried walking but her legs were still half rubber.  Lily held her up and kissed her sister deeply, then whispered, "Some time, if you’re up for it, I’ll teach you how to do those things to a girl.. like me."

They found their way to the shower and before she reached in to turn the water on, Lily leaned in close and nipped at Em’s ear. Then she said, “I really want to fuck you some time, Em… soon.”

Emily let slip an unintentional “Unf!” and half-joked back to her baby sister, “Yeah, too bad you don’t have a nice big cock.”

Lily felt a jot run through her, and quickly said, “Hop in there, babe. I forgot something. Be right in.”

A few minutes later, Lily appeared with the perfect addition: her waterproof harness and a big veined 10-inch strap-on dildo affixed to it.

"Did you order a big cock, miss?"

"Holy fuuuuck!" Emily roared. "Oh fuck oh fuck….." which in Em-speak, translated to "How the fuck can I ever say no to that, attached to someone who knows how to make me cum harder than anyone I’ve ever fucked?"

Lily could see the lust in her sister’s eyes, still lost in the fog of her last O’s.

"Bend over, babydoll" Lily purred wickedly, "Your hot little cunt is mine."

Emily’s will was jello. If Lily had asked her to suck the cock, she would have knelt and worshiped it. Emily finally said, in a really filthy tone, “Make it good, little sister. I don’t want to have to tell my friends you’re a lousy fuck too.”

in a flash, Emily was bent over, holding onto the silver handles on the tiles, and her sister was ramming a monster cock, balls deep, fucking her better than any man had yet in her sexual life.

Lily eased the rhythms now and then to lean over and talk dirty into Emily’s burning ears.  “If you’re a good girl”, Lil growled, “I’ll let you fuck me sometime. Hell, I’ll make you fuck me!”

At one point she taunted, “Wait until I fuck your hot little asshole over the kitchen table like this.” That somehow hit a mark in big sister, and Emily finally flat out begged. “Fuck me, Lily, just fuck me until I can’t walk!!”

By the time this ramming girlcock session was over, the water was cold and the girls were on the tiled floor, Emily was face down and ass up, breached to the hilt and still cumming. Lily was rocking with her faux cock fully embedded in her sisters pussy walls, a fistful of Emily’s hair in her hand, and rocking her own orgasms from the friction of the strap-on cockslam, as it rubbed her endlessly against her hungrier-than-ever clit.


"Your bed has a big wet spot" teased Lily. "Come sleep with me in mine."

The girls cuddled up close in Lily’s bed, and Emily clung to her little sis like she was a soft teddy bear. Emily kept whispering, “Oh my god… oh my god.”

"Promise me you’re not going to get weird on me tomorrow, Em." Lily said softly. "We tried something. It’s fine. That’s what young horny girls do. Yes even sisters sometimes. And if you don’t want to do it again… well, I won’t make you" She could feel Emily relax. Then she added with a naughty tease "But I’ll still want to." She laughed.

"Kay", Emily answered, nearly half asleep. "Promise me…."


"That you’ll always fuck me that good."

Lily beamed in the darkness of the room. “Count on it, Em.”

Emily chimed in “I’ll keep your secrets…”

Lily finished “And I’ll keep yours.”


The next morning, Lily awoke to find Emily gone from her bed. It set off a whirl of worry in her wine-thumped head. She grabbed her cell phone and texted Emily.

"Where’d you go?"

A moment later came the reply. “B’kfast and coffee are ready. I owe you for the O’s. Come and get it.”

Lily decided to play princess. “What, no b’kfast in bed?”

There was a noticeable pause, then Em’s text rang in. “You said you wanted to fuck me over the kitchen table.”  Emily knew that would get Lily up and running.

Lil was downstairs in record time, her arms wrapped around her big sister, their mouths sharing morning kisses.

"You okay?" Lily asked seriously.

Emily offered quietly, “I’m a little weirded out. I mean… first bi sex is enough right there. Then having it with my own sister.  Fuck! Okay, and  yes, a little sister who, by the way, is the hottest fuck ever.” They laughed and kissed. 

Then Emily moved back again and continued, “I thought I should keep my mind open a bit longer. Be nice to find out if I liked cumming in your face and being fucked into oblivion by my little sister… without the wine.”

"You really should learn the other side too, in case you meet a hottie at school" added Lil. Then she whispered teasingly, "Who will never be as good as me."

They sipped coffee, and chowed down in hungry silence, even sharing a soft kiss or two between bites.

"One thing", Emily said, as she cleared the table after their meal. "Next time you fuck me, can we do it face to face? I really want to see your face when you do. And your orgasm face. And pinch your nipples when I want it harder." She playfully pinched Lil’s nips and the heat began to ramp up once again.

Soon, Emily would be on her knees tasting her sister’s wetness for the first time, and not long after, she would be rocking face-to-face, riding the big girlcock, willfully kissing her seductive little sister, and whispering, “I love you, Lil.”

I love you, Em.”

"Fuck me like you mean it."

"Count on it baby. Just don’t tell."

They had 8 more days without their folks there. They would break the orgasm barriers and try things even Lily hadn’t considered, by the time those days had passed.
