By offering your Momma your Sister's pussy instead

You're not quite sure where this plan came from, some dark corner of your mind that was always there but mostly went unnoticed, or perhaps a new dark area that's been awakened by your Younger Sister's antics, in any case, you decide to embrace the idea. So with a look of confusion from both Lyra, who's still feigning sleep, and Momma Genevive you move towards your Sister's seemingly slumbering form and slowly lift the covers up, revealing your Sister's naked body to your Momma.

"Sweetie, you can't be suggesting what I think you are," Genevive whispers in disbelief.

"Don't worry Momma," You reply with a wicked grin. "Lyra's a really deep sleeper, I've fooled around with her loads and she's never woken up," You add with a smile.

"Sweetie, I really don't think this is a good idea," Genevive replies nervously.

"It's fine, watch," You reply, raising a hand and spanking your Sister's ass very hard, the heavy slap reverberates around in the otherwise silent night. Fortunately, Lyra already has something in her mouth to muffle the cry of pain from you spanking her like that and can sell the act of being a heavy sleeper.

"Oh wow, she really is a heavy sleeper," Genevive replies in disbelief as she watches her Daughter's hand print begin to form and redden on her other Daughter's ass.

"Yeah, now let's just see if she's been having sweet dreams and might already be wet enough for you, Momma," You say, rolling Lyra onto her side, which gives her a chance to get comfortable without Momma Genevive noticing. "Must be having a nice dream, she's rock hard and dripping wet," You say with a giggle running your hands over Lyra's big hard cock and swollen balls, before sliding your hand further back until your fingers are resting on Lyra's juicy folds. "God futas are sexy," You growl seductively, sinking your fingers into Lyra's hot slippery channel.

"Yes we are," Momma Genevive replies with a giggle.

"Ever been with another futa before?" You ask with a grin.

"Once, a very long time ago," Genevive answers leaning in and admiring Lyra's body. "Always wanted to try being with another," She adds slowly licking her lips.

"Well here's your chance, Momma," You reply with a smile. "She's wet and ready for you," You add slipping your fingers out of your younger Sister's sex and thrusting the dripping digits into your Momma's face. "Doesn't she smell divine?" You ask in a sensual tone.

"She does," Momma Genevive replies swallowing hard as she catches Lyra's sweet scent from your fingers.

"She tastes even better," You purr, adding more unnecessary fuel to the fire as your Momma opens her mouth and takes your fingers sucking the juices from them, her cock twitching heavily.

"Oh Sweetie," Genevive replies after a good minute of sucking your Sister's juices from your fingers. "You're right, but I really shouldn't, not while she's sleeping," Genevive replies, still hesitant to go through with your plan, although you can already tell that her resistance is a token effort at best.

"Of course you can, we just need to line this," You begin, reaching down and wrapping your slender fingers around your Momma's thick hard member. "And line it up like so," You continue, gently pulling your Momma's cock closer and closer towards Lyra's pussy. Genevive awkwardly shufflingling closer on her knees making no attempts to stop you.

"Sweetie, I can't," Genevive protests, although she does nothing to move her cock away from Lyra's sweet soft and inviting folds. "I want to, believe me, I want it as badly as I want you, but not while she can't agree to it," Genevive replies in a needy tone.

It's a painful thought to try and back down now when you're so close, just one small thrust, your Momma could be inside Lyra, but your Momma's words finally break you out of your daze and what you're trying to do finally sets in. A wave of guilt about what you're trying to do to get Momma Genevive to do to Lyra without knowing if she even wants this makes your stomach start to churn. For the first time, you start to wonder if you've gone too far and if this was a huge mistake as panic starts to set in.

Fortunately, almost as if sensing your hesitation or misgivings Lyra comes to the rescue by being the one to move, arching her back and pushing back at just the right angle for her sweet slick lips to part around her Momma's cock and sink inside of her. Genevive lets out a low moan of raw pleasure as inch after inch of her cock sinks into Lyra's sweet sex, the concerns and hesitation melting away as pleasure floods your Momma's mind. It's a wonderful sight that almost immediately calms your mind and snaps you back into the lusty confidence you had before.

You watch in fascination as your Momma begins to rock herself back and forth, her large futa cock sliding in and out of your Sister's hot wet snatch, the inner lips of Lyra's folds gripping your Momma's shaft as she slides out before thrusting back in. You feel yourself getting wetter from watching your Momma fucking Lyra, Lyra's moans of pleasure are lost to the pillow she's clutching to her face. You see Momma Genevive's heavy balls slapping against your Sister's ass cheeks, an illicit thrill running through you as you realise there's nothing between your Sister's womb and the seed-swollen swinging sacks she once came from.

"That's it, Momma, Fuck my Sister," You coo softly into her ear. "Fuck her like you wish you could fuck me," You tease, resting your hand on your Momma's back and gently encouraging her to thrust faster.

"Oh, Sweetie," Genevive purrs in reply. "You're so wonderfully wicked, getting me to fuck your Sister like this," She adds picking up the pace and thrusting faster and harder.

"It's ok, you'll just have to make it up to her, by letting her fuck you," You reply with a sensual giggle.

"Mmmmm don't tease Momma with promises like that," Genevive growls

"Just imagine it, I'll be at the front, taking your big hard cock inside my tight little pussy, while Lyra pounds you from behinds, a delicious daughter Momma Sandwich, with plenty of creamy filling," You purr in a sultry tone.

At this Momma Genevive's thrusting grows much harder and her thrusts grow more erratic as your words seem to drive your Momma into a frenzy. You notice Lyra is struggling to keep up the sleeping act, her toes curling and legs trembling as your Momma's cock thunders in and out of your Futa Sister's slippery sex, even her moans are starting to escape from around the pillow from the thrusting. Fortunately, Genevive is far too caught up in the illicit rush of fucking her own futa Daughter and the sweet fantasy of being in the middle of both of them.

This frantic pace continues for some time, at one moment your Sister's face slips out from the pillow she was burying it in, and you can see from the expression on her face, that she's thoroughly enjoying every moment of this. You smile to yourself and look over to your Momma a look of fierce concentration on her face as she's trying to hold back her orgasm, wanting to enjoy this for as long as possible. You decide to try and give Lyra a helping hand in more ways than one, by reaching over with your free hand and taking her swollen cock into your soft hand.

You feel Lyra's cock twitch in your grip, the forceful impacts of your Momma pounding away at your Sister's pussy causing Lyra's body to shake effectively making her fuck your hand. With one hand on your Momma's back gently pressing her forward to encourage her pace, while Lyra's cock pistons in and out of your other all you have to do is sit back and wait. Minute after glorious minute passes by, the scent of sex dominates the air in the tent as you feel your Sister's cock slowly hardening in your grip as her orgasm begins to mount.

"Oh fuck, Momma's getting close," Genevive warns just a few minutes later. "Want another taste of Momma's cum?" She asks with a groan as her cock begins to throb and pulse deep inside Lyra's pussy as your Momma nears her limits.

"I sure do Momma," You reply with a giggle.

"One hot creamy treat coming right up," Momma Genevive growls as she attempts to pull out of Lyra, only to find resistance as your hand pushes back against her. "Sweetie, Momma needs to pull out," Genevive groans her cock giving a warning throb as her heavy balls begin to drag upwards as she's moments away from cumming.

"No, I want to eat it from Lyra's pussy, get the best of both worlds," You reply with a giggle.

"As hot as that sounds, Sweetie, we can't risk it," Momma Genevive warns.

You know it's wrong but something about the word risk in this context sends a thrill through your body, the thought of your Sister's sperm in your own womb coming to mind. The idea of Lyra's getting knocked up by your Momma makes your entire body shiver with illicit thrill as you press even harder into your Momma's back keeping her from Pulling out. "Please Momma," You coo seductively, your words causing Lyra's cock to twitch in your hand as she realises what you're begging your Momma to do.

"Fuck, Hope she doesn't wake up," Momma Genevive groans as she thrusts herself into her Daughter's sweet sex one final time before her cock begins to erupt deep inside Lyra.

You watch in delight as you see the base of your Momma's cock throb and pulse as the eruption of cum floods Lyra's pussy, the sensation more than enough to get your Sister off as her cock begins to jerk wildly in your hand as she starts to cum. You smile as you continue to stroke your Sister's cock until she finishes cumming, turning your attention to your Momma, who's breathing heavily as she milks the last of her load into her Daughter's pussy before finally pulling free of Lyra's sex.

You quickly take her place, burying your head between Lyra's thighs, your tongue lapping at her still twitching pussy as you devour everything it has for you. At first all you can taste is Lyra's juices, your Momma's creamy surprise seems to be buried deep inside your Sister, but soon you start to notice the flavour and consistency of the fluids leaking out of Lyra change. The sweetness of her feminine flavour mixes with the wonderfully tangy flavour of your Momma's cum, something you enjoy so much you decide to share some with your Momma.

Getting a good mouthful of Lyra's juices and a healthy amount of Momma Genevive's cum, you pull away from Lyra's sweet rear, giving your Momma a moment to admire her cum lazily leaking from Lyra's well fucked pussy, before you press your lips to hers. Your Momma wasting no time parts her lips to give your tongue access, only instead to have you push the delicious cum mix into her mouth. You pull back giggling at the look of surprise on your Momma's face before she laughs and swallows the cum mix.

"Been a while since I got to taste myself," Momma Genevive say with a smile. "Better than I remember," She adds with a grin.

"See why I had to try it now?" You ask with a grin., the pair of you share a laugh together.

"I still can't believe she didn't wake up," Momma Genevive says in disbelief, looking down at Lyra's still form.

"Yeah, we're lucky there," You agree with a smile.

"Speaking of luck, I should probably stop pushing mine and get back to your Mom before she wakes up and wonders where I am," Momma Genevive says with a smile. "Hopefully we can do something like this again?" She adds with a big smile.

"Yeah, maybe with Lyra awake so she can enjoy it too," You reply with a smile.

"Do you think you can convince her?" Genevive replies with a tone of nervous hopefulness.

"I have my ways, now go back to Mom, I'll handle the clean up," You reply, leaning towards your Momma and kissing her on the lips.
