The cool uncle


8th: Both then strip naked (Naturally they have big MILF bodies) and say they want to have fun like old times...And there's no need to be worried about Sonic and Knuckles since they've agreed on open marriage when it comes to the sex.


9th: Shadow then ravages the MILF's


10th: Finally all 5 are resting and Knee and Sarah thank Shadow for ''showing'' them new things...And while they still prefer women they're willing to have fun with Shadow in future 


“You know, Knees, I was thinking about something…” Sarah muttered while she and her lovely fiance Knees laid on the couch, the azure hedgehog laying her head on the prosperous echidna’s lap.
“Yes, Sarah?” asked the red-striped echidna, raising a brow.
“I was thinking: what would it feel like to have sex with a dude?” asked the lesbian hedgehog, twiddling her fingers while looking surprisingly thoughtful about it.
“W-What? W-Why do you ask me this?” asked the striped echidna, gulping and blushing. She knew how direct Sarah was, after all she was the daughter of Sonic, but to be asking something so… weird so suddenly?
“I dunno. It’s just… Mom and dad always told me that I can’t say I don’t like something before I try it out. We have each other and we have tons of adult fun, that’s undeniable, but… I never actually TRIED to be fucked by a man before, so I don’t know how it feels.” Sarah explained, waving her hands in the air as she talked.
“W-Well, neither have I, but… Isn’t this a bit too random? I mean, are we supposed to go ask someone we know ‘Hey, can you fuck us so we know how dick feels like?’, just like that?” asked Knees, she always had been scared of trying new things out, but that was basically Sarah’s job: to help her fiance to open her mind.
“Well, I wouldn’t ask a random guy… We could ask some of our dads’ friends.” Sarah hypothesized, which made her echidna girlfriend feel even more uncomfortable.
“You mean, ask one of the many guys who watched us grow and treated us like family? It’s unrealistic. I mean, who would even consider it?” asked Knees, sighing and groaning. At that, Sarah groaned too as she thought of who to call, but then after a while her ears perked up and a sly grin formed on her face, making Knees worry a lot since she knew what that face meant: trouble.
“I think I know who wouldn’t mind…” she chuckled as she picked her phone and dialed a certain number of a certain hedgehog.


Shadow hummed a bit as he headed to one of Sonic’s houses which he gifted to Sarah and Knees once they turned 18. He was kind of surprised to receive a call from his archrival’s daughter, especially such a shady call since she asked him to come over very swiftly, without explaining why. But he shrugged it off, thinking that maybe she would explain better once he got there. He arrived in front of the door of the quaint green and white house and knocked on the door, having it open by Knees.
“H-Hi Shadow…” she stuttered, not looking at him for some reason.
“Oh please, Knees. You can call me Uncle Shads, after all I’ve known you ever since you were this tall.” he said smiling and placing his hand at the height of his knee, which was how tall Knees was when they first met. But now Knees was actually taller than him and she truly showed to be her mother’s daughter with her massive curves, especially her huge, wobbling breasts barely covered by the ivory tank top she wore.
“H-Heh… Yeah…” she said, giggling nervously and making him walk inside. He went in and headed for the living room, while Knees followed with her head down and a faint blush across her face which, for now, Shadow didn’t notice. Then he saw Sarah, laying with her right on the couch, kinda showing off a bit.
(It’s such a Sonic thing to do...) Shadow chuckled as he saw a lot of him in her. “Well, here I am. What can I do for you, girls?” he asked, standing in front of the couch as Knees went towards it, then Sarah got seated and scooched a bit to let her nervous fiance sit next to her.
“First of all, thank you for coming over with so little advice, Shadow. I appreciate it.” said Sarah smiling and placing a hand on Knees’ thigh, making her coo a bit and place her hand over Sarah’s.
“Of course. Now, what do you need me for?” asked Shadow, he had to admit he was getting curious.
“Easy. I want you to fuck us.” Sarah said blatantly while Knees sighed and rolled her eyes a bit.


Shadow stood there, not moving a muscle and blinking confused.
“I… beg your pardon?” he then asked, raising a brow.
“You see, I was curious about what it would feel like to be fucked by a man, and I figured you’d be perfect since you’ve always been so kind and cool to us, also you had histories with our moms and they told us how great of a guy you are, so I thought to ask you about it.” Sarah explained while Knees gripped her fiance’s hand a bit tighter.
“Well, I came prepared for the unexpected, yet you asked me something even more unexpected. I can't help but feel a bit shocked about this since, as I told you, I’ve known you ever since you were kids, but I also feel strangely honored that you thought of me of all people. Girls, you can count on me.” he said smiling and putting his thumb up.
“Great! Knees, aren’t you excited to be fucked by a man?!” asked Sarah, looking giddy.
“Not really…” Knees whimpered slightly “B-But, if you do this, I will too… J-Just please, be gentle…” she then cooed to Shadow, who nodded.
“Of course I would. I know how delicate you two are, especially you, Knees, so I will be gentle. After all, what kind of cool uncle would I be if I hurted you?” he asked, winking cornily.
“Tee hee… Ok, honey. First, I do believe he needs to be ready for this, which meeeeans… Lesbo cuddles!” Sarah giggled and tackled Knees, topping her on the couch and making her blush.
“W-With him watching?! I-I don’t know… I’ve never… W-We’ve never done it… I-In front of s-someone else…” Knees stuttered, Shadow had to admit that, for being a big and strong girl, her submitted personality made her even cuter.
“Me too. Isn’t it exciting?” asked Sarah, giggling and wagging her tail as she held her fiance’s wrists, looking down at her with the gentlest of blushes coloring up her peach skin.
“Besides, if we start with something you’re more familiar with, maybe you’ll be more open about what’s to come…” said the azure hedgehog as she leaned on Knees, their boobs pressing against each other as she did which made Knees squeak a bit, then Sarah gently pressed her lips onto Knees’ for a peck.


Knees’ resistance immediately melted as Sarah kissed her, and cooed as her fiance’s hands left her wrists, slowly sliding up her arms and shoulders until they cupped her cheeks. Knees slid her arms around Sarah’s thin waist and pulled her closer, their boobs mashing more against themselves as she did, and opened her mouth, which Sarah immediately took advantage of and deepened the kiss, adding some tongue for a seductively effective French kiss. Shadow took a chair and sat down, watching the two kiss with a small smile on his face. He remembered how much trouble they had with their relationship, mostly because Knuckles couldn’t accept the fact that his daughter was lesbian, but he too was forced because his wife, Sonic and Amy were all okay with it. Now they lived together and were happy, so everything went fine, despite their rocky start. Their quiet moans filled the room as they continued to lovingly kiss while holding each other, which made Shadow’s heart skip a beat because it had been so long since he witnessed such a pure, simple demonstration of love. Eventually Sarah pulled away to breathe, but they kept looking at each other, panting slightly and blushing while they got lost in each other’s eyes and smiled. Sarah’s hands migrated from Knees’ cheeks to her shoulders, then to the edge of her tank top and raised a bit before she slowly started to take it off. Knees bit her lower lip and blushed but she still raised her arms to help her girlfriend slide it off, freeing Knees’ impressive boobs from the clothing and making them flop and bounce around for a while.
“My gosh… I’ve seen them so many times, yet everytime I can’t stop admiring how sexy your boobs are, Knees…” Sarah cooed as she too took off her shirt, revealing her own tits. She was much smaller than Knees, yet her curves were still nice. Knees had an I cup and Sarah had an F cup and Shadow also noticed that Knees had inverted nipples.
(Huh, nice to know...) he thought, watching them.
“Mgh… It’s just fat… It shouldn’t be anything special…” Knees murmured, covering her mouth with one hand.
“But it is special. It fits your form, it adds to your already insane charm and…” Sarah giggled as she listed the pros of her fiance’s copious tits before she buried her face in her cleavage.
“...It makes you the best damn pillow!” she cooed in the end, giggling as she nuzzled Knees’ tits.


Knees rolled her eyes and shook her head, but she did so with a calm smile as she petted Sarah’s head.
“Love, you’re such a hopeless boobhead…” chuckled the echidna as Sarah motorboated her tits.
“I know and I wouldn’t change it for anything in the world.” Sarah chuckled back, her words muffled by Knees’ boobs as she kept nuzzling with them, then she greedily groped the front of her tits, starting to massage them while Knees’ blush reddened.
“Mmmm…” the echidna cooed as Sarah massaged her tits, after many years together the hedgehog knew exactly how much pressure she needed to apply in order to make Knees feel good while not groping her too much. Still, Shadow saw how much of Sarah’s hands vanished into Knees’ titflesh, meaning hers had to be pretty darn soft. Sarah sat on her knees, her legs spreaded to accommodate Knees’ bent legs within them, and kept fondling her fiance, purring and cooing with every grope she gave her and relishing in the pleased squeaks she gave. Knees kept gently moaning, then she too started groping Sarah’s ttis, making her giggle and coo as she felt her lover’s strong hands grope them.
“You know the drill, babe. Go as hard as you like with me. I can take it.” Sarah said to Knees, who nodded and squeezed the hedgehog’s tits, making her grit her teeth and wag her tail as she did, then they locked lips again and made out while fondling each others’ boobs. Shadow watched with hungry eyes as they took care of each other perfectly, like an oiled machine they moved in perfect sync and knew how to turn each other on while not losing their bodies’ harmony. Soon, Sarah pulled away from the kiss and giggled.
“Hey, let’s show him our thing.” she said, while both kept groping each other.
“Which one? We have so many things that are ours.” replied Knees.
“You know… The one with my and your n…?” Sarah asked, trying to give her fiance a prompt, which she caught immediately.
“Oh, THAT thing. Ok.” said Knees, blushing even more. They got on their knees a bit away from each other, making Shadow wonder what they talked about, then Knees cupped her tits and lined them up with Sarah’s boobs, precisely they lined their nipples together.
(Wait… Are they…?) Shadow thought, leaning on the chair with widened eyes. Sarah giggled at his reaction, he must’ve figured out what they were about to do, then she moved closer and pushed her slightly longer nipples inside Knees’ inverted nipples.
“Mmmmffff!!” Knees moaned and hugged Sarah closer, their boobs pressed together harder as they started to move back and forth on each other, both moaning as Sarah basically fucked Knees’ nipples with her own.


“Oh fuck… Didn't know you guys were into that…'' Shadow muttered, smirking sensually as this whole ordeal already turned him on. Sarah squeezed her eyes shut and rubbed Knees’ back while she thrusted her nipples inside her fiance’s, making her moan louder and shutting herself up by deeply kissing Sarah and topping her this time. Sarah squeaked as Knees was bigger and heavier than her but she didn’t mind the weight and kept thrusting inside her tits while moaning in her lips. Knees actually teared up in bliss as they did so and Shadow swore he could hear a sloshing sound coming from the echidna’s boobs.
(Milk? But how? She’s not possibly pregnant…) Shadow thought as he kept watching the two make out and moan during the nipple fuck, which went on for a bit until, with a deep blush, Knees pulled away from the kiss and screamed in bliss as she lactated, which pushed Sarah’s nipples out of her own as they grew hard and came out of their fleshy encasing, unlike Sarah’s, Knees’ were thicker and surrounded by a pretty wide areola.
“Wait, what?! She’s lactating?! How?!” Shadow asked, confused while he saw Knees panting as milk trickled down her tits.
“Mmff… Heh, it’s because of the Chaos energy inside her… It causes her body to produce milk even without being pregnant. Which is super hot since, guess what I’m also very much into?” asked Sarah, chuckling before she lunged upwards, groped Knees’ boobs and pushed them on her face, taking both nipples in her mouth as she greedily sucked them, drinking her milk.
“Mmnngghh… Ooohhh… Hhhnnn…” Knees moaned, clearly loving what was being done to her.
“Mmm… Mmm… Mmm… Mwah! Oh, she so loves it too!” said Sarah, parting just a bit to speak before she sucked her nipples back in her mouth, greedily slurping on them and gulping her milk.
“O-Oh gods! Oh gods, yes! M-My tits… My tits, suck them! Suck them good, yes!” Knees moaned again, showing how much into it she was, and pressed her tits more onto Sarah’s head, which was completely covered by a fleshy avalanche. Sarah didn’t seem worried at all and just kept drinking, her thirst for her fiance’s Chaos-infused breast milk seemed endless and milk trickled down her cheeks as it started to overflow, yet she still didn’t care and kept sucking and sucking, showing an insane resistance and willpower. 


After a bit, Sarah pulled away, panting and blushing as her face was smeared with milk.
“B-babe… Mine too…” she cooed. Shadow blinked and saw that, now, even Sarah's tits were leaking milk.
“How about that?” asked the Ultimate Lifeform, more curious than confused this time.
“Hnf… I too have a large amount of Chaos energy inside me, which helps me turn Super without the Emeralds, and I found out that her milk’s Chaos reacts with mine, making me lactate too.” she explained while moaning. Knees moved Sarah more to the center of the couch and laid on her with her head pointed towards Sarah’s crotch then she lowered down and sucked in Sarah’s nipples, drinking her milk too. While doing so, she pressed her tits onto Sarah’s face so she of course sucked Knees’ nipples back in her mouth as they both blocked each other into a pretty sensual session of breastfeeding which had Shadow gulp as he never had seen anyone do that before. They both drank each other’s milk, both looking so entranced with each other’s taste and locking themselves in a loop: Knees’ milk made Sarah produce more milk for the echidna to drink and refill her body with Chaos energy which turned into milk.
“MMMBBB… MMMBBB… Haaaah, we… we usually get so locked up with this… Sometimes we can go on for hours… MMMLLLPPPHHH…” Sarah managed to mutter before she was silenced by Knees’ nipples again pressing on her face and almost forcing themselves back in her mouth.
“MMMFFF… MMMFFF… Mwah… Yes… Yes, we… W-We are addicted to this… To each other… A-HUM!” Knees moaned as she too talked before sucking Sarah’s nipples back in her mouth, smothering more of her fiance with her thick body. Shadow was almost worried that they might get lost in their pleasure, but eventually they basically forced each other to stop as they readjusted their position while they took off their pants as well, Knees still laying on top of Sarah but now she raised up and sat on her fiance’s face, pressing her pussy on her muzzle while she panted, then after she regained some breath, Sarah groped her ass and started eating her pussy.


“MMGGHH… OOOHHH!!!” Knees moaned loud, blushing hard and shivering as Sarah ate her, something she never failed to enjoy. She bit her lip to try and not moan so hard, but Sarah had every intention to make her moan so she penetrated her pussy with her tongue, which was super effective and made Knees blush brighter and grit her teeth, but it was pointless for her to resist so she moaned as hard as she could, tearing up in bliss as Sarah made her feel great. Knees leaned on her and grumbled a bit, then she too started eating Sarah’s pussy making her moan but continued nevertheless as they locked each other in a 69 which had Shadow and his nether region very interested, making him wag his tail and smirk as they did it. They kept at it for a good half hour, until they both moaned and came, holding each other as they shivered in the aftershock. Then, once it was over, they sat up and looked at Shadow, widening their eyes as they saw Shadow’s huge cock.
“Oh fuck… Not even our biggest dildo is so massive…” said Knees, looking at her pussy with worry as she wondered if she could take such a thing.
“It’s so big and thick! Can it even fit?” asked Sarah, looking at it in amazement.
“Only one way to find out. I’ll handle you one at the time, so who wants to do it first?”  Shadow asked, smirking and making his cock wave a bit.
“...I will.” Knees said, making both look at her.
“Babe? Are… Are you sure?” asked Sarah.
“I am. Like you said, I need to get out of my shell. Plus, I still feel horny after our session.” said Knees. Sarah nodded and kissed her cheek before getting up from the couch and leaving room for Shadow to lean on Knees, making her blush and look away.
“Don’t worry, Sarah lubed it up with her saliva so it should slip in easily.” he said, lining his tip with Knees’ pussy entrance. She nodded and tried to look brave, when she couldn’t have been more scared. Shadow knew that so he petted her cheek to comfort her.
“Hey. Look at me.” he said, to which she complied and disclosed one of her closed shut eyes.
“You know me, right?” he asked, making her nod.
“You know I care for both of you, right?” he asked again and again she nodded.
“Then you know that I would never hurt you. The second you start to feel pain, you tell me and we stop until you feel better. Ok?” he asked.
“O-Okay…” she stuttered, then she took a deep breath and opened both eyes “I-I’m ready…” she said then, to which Shadow nodded and gently pushed his tip inside her.


It was merely the tip but she already threw her head back and yelled through her gritted teeth as she held Shadow’s sides.
“Oh crap, I’m sorry! Did I…?” he asked, lowering his ears.
“No, no, no. Wait.” said Sarah, going next to Knees and sitting next to her, cupping her face.
“Babe, are you ok?” she asked her fiance, who opened her teary eyes and looked at her.
“I-It f-feels s-so w-weird… I-It’s h-hard a-and h-hot a-and s-so t-thick…” she sobbed, grabbing and holding Sarah’s hand.
“I… I’m s-scared…” she bawled after, tears could no longer be controlled as they flowed down her cheeks.
“Hey, hey, babe, look at me. Look at me.” Sarah said, cupping her cheeks and making her look in her eyes.
“I’m scared too, ok? Of course I am, it’s the first time I concede myself willingly to a man, to top it all off a man who knows us from the moment we were born. It’s completely natural, but you don’t have to let it overwhelm you. Control it. say top yourself ‘Alright, you stupid brain. Now we do things my way. My beautiful, super smart fiance is right: there’s nothing to be afraid of and Shadow won’t hurt me, instead he’ll show me one hell of a good time.’ Got it?” she said to Knees, who weakly nodded.
“Say it.” said Sarah.
“...A-alright, you stupid brain. Now… Now we do things my way…” she started muttering.
“Stronger! Let it know who’s boss here!” Sarah pep talked Knees, who felt immediately more motivated.
“My… My beautiful, super smart fiance is right: there’s nothing to be afraid of and Shadow won’t hurt me, instead he’ll show me one hell of a good time!” she yelled out of the blue, making them wince a bit.
“Okay, that came out awfully strong but… How do you feel now?” asked the hedgehog to the echidna.
“I… I do feel better. Thanks, Sarah.” she said smiling “And, Shadow… Sorry for that. I overreacted. It… actually doesn’t hurt that much. You can push more inside.” said the echidna then, looking at the Ultimate Lifeform.
“Okay… As long as you’re sure…” said the ebony hedgehog as he pushed more inside. Knees hissed lightly as it filled her inner channel, then Shadow started thrusting extremely slow and delicately, to avoid hurting her.


“Mmfff… Mmff… F-Feels like a d-dildo… But warm…” Knees commented, biting her lip and squeezing Sarah’s hand, who smiled and petted her.
“You’re doing great, babe.” she cooed and planted a kiss on her forehead. Shadow groaned as he gently fucked Knees, then he eyed her tits: even if he wasn’t going strong at all, they still flopped and sloshed, full to the brim with milk that he definitely wanted to taste.
“Hey babe, I think uncle Shadow wants a taste of your yummies.” Sarah giggled and rubbed Knees’ palm with her thumb.
“Mmm… G-Go ahead, Shadow…” Knees moaned. Shadow’s face lit up in joy as he gently kneaded and rubbed Knees’ tits while he sucked on her nipples to drink her milk, wagging his tail as it tasted great.
“Hihihi, look how happy he is. And you say I’m the boobhead…” Sarah chuckled, then she cupped Knees’ cheeks and kissed her, cooing and wagging her tail as well. This went on for quite some time, eventually Knees had grown adjusted enough to ask Shadow to go a tad faster, which he complied by bucking his hips more onto her, slapping his meat inside her a bit more hard but still being extra conscious of not hurting her. Eventually, Shadow groaned as his dick twitched inside.
“Hhgghh… Girls, I think I’m…” he groaned, getting closer to release.
“Mmmfff… Mwah! Babe? Your choice. What should he do?” asked Sarah, pulling away from Knees.
“Mngh… I-Inside… It’s n-not my fertile d-day, so you can c-cum inside… Man, I never knew I’d get to say that to a man…” Knees commented between moans. Shadow gritted his teeth and released his load inside the echidna, making her grit her teeth and squirm a bit as she felt the hot, sticky sperm fill her womb. The echidna kept moaning and panting until Shadow pulled out, cum leaked out of Knees’ pussy as she kept breathing harshly.
“So? How was it?” asked Sarah, smiling.
“Mnf… N-Not too bad… But I still prefer pussy…” Knees moaned and giggled.
“Heh, figures. Now do me!” said Sarah, giggling excitedly as she saw that Shadow was still hard.
“Heh, straight to the point, huh? You’re truly your father's daughter…” Shadow chuckled as they moved to the chair he sat on before while Knees rested on the couch, watching the scene about to unfold.


Sarah sat on Shadow’s lap, his cock gently nestled between her asscheeks, and she wrapped her arms around his neck, pressing her generous rack on his huge pecs, giggling.
“Mmmm, not bad for an old dude…” she giggled mischievously.
“Good thing I know you meant it as a joke, or else things might’ve gotten ugly…” Shadow commented, snickering.
“Ok, whenever you’re ready, uncle Shadow. And remember: I can take it. Don’t spare me like you did with Knees.” she said, biting her lip as she was dying to feel it.
“If you say so. But if you think you can’t take it, tap on my shoulders, ok?” asked the Ultimate Lifeform, not wanting to hurt her too.
“Yeah, yeah. Now get on with it already!” she huffed, which made Shadow chuckle as she was just like her dad. He rubbed his cock between her asscheeks a bit, then he raised her hips and pushed his tip inside.
“Ugh… Mmm… It… It feels bigger than it looks…” Sarah commented through her teeth.
“You don’t need to put it all inside, you know?” Shadow reminded her, but she shook her head.
“If-If Knees could take it all inside, then I can too…” she moaned and started to slide down his cock, hissing as she did but she managed to put it all in.
“Mmmnnnggghhh…” she groaned, hugging him closer.
(K-Knees was able t-to put THIS inside her? She’s s-so much stronger than me… B-But I won’t back down…) she thought, her mind already hazy and he just put it in. 
“Mfgh… You’re so tight, little Sarah…” Shadow mumbled, taking a hold of her shapely butt.
“...” Sarah remained utterly speechless as her heart skipped a beat: for some reason what he said and how he said it made her feel much more flustered than usual.
“I-I’m n-not…” she whimpered, looking away while a timid blush formed on her face. Shadow acknowledged this and smirked as he made her stare directly in his flaring ruby eyes.
“Yes, you are… To me, you’ll always be the little bundle of hyperactive joy that made me play as Perfect Chaos while you played as your dad…” he kept whispering, seeing how red she was getting now and how she tried to not look in his eyes, but he made sure she would so he could see her flustered face.
“S-Stop s-saying t-this… Y-You… You’re m-making m-me all… F-Fidgety…” she whimpered more, as Shadow started to thrust inside her while he petted her air.
“You like to play dominant, but deep down you crave to be dominated too… And you love being pampered and complimented on while in the act of love… Aren’t you the sweetest?” Shadow asked, grinning as he humped her gently but much more firmly than when he did it to Knees, making her squeak every time he’d hit her deepest spot and relishing in how tightly her pussy clamped onto his cock whenever he’d pull back and in the blushing mess she became.


Knees was speechless: she had known Sarah for so long and had been with her for ten years and not once had she seen her dominated. She was the dominant one of the two: despite Knees being stronger, Sarah was bolder and would always come up with new erotic things to do. Seeing Sarah like this, so frail and so much like… Knees, was completely new for the striped echidna. Shadow growled lightly as he fucked Sarah, who moaned and blushed as Shadow's thick, fat cock thrusted inside her pussy, then Shadow Pushed her down, making her lay on her back and humping her pussy with a mating press that sent her over the edge and begging for more while drooling and crying in bliss, she would’ve never guessed that a cock could make her feel this good. Shadow would hump her for twice the time he fucked Knees since Sarah swore she could take it but he realized how wrong she was: she was a tearful and blushing mess, her pussy clenched tighter each time Shadow would withdraw his cock as it started to throb. Shadow bit his lip and, with one final thrust he came inside her, making her moan loud as the cum rushed inside her, filling her womb. Once he was done he pulled out, his cock still hard despite all of that, and Knees rushed to Sarah, helping her out.
“Are you ok?” asked the echidna, concerned.
“N-Never… B-Better…” Sarah managed to whimper between moans and raw panting. However, Shadow wasn’t done with them yet as he still had one last surprise for them. Luckily, he didn’t forget his trusty syringes so he reached for them and took three, injecting all of them in his cock. The two girls watched, first with confusion and then with awe, as first he split in two, then both clones gained two cocks and finally said cocks split into six more units and became longer like tentacles, waving in the air.
“O-Oh boy… He used the serums that uncle Tails made him…” Sarah cooed, wagging her tail. The two Shadows came closer and their cocks darted at the girls, wrapping around their luscious bodies. Sarah’s arms were tied behind her back while her belly and legs were wrapped too, her legs were actually spreaded, and Knees was tied up with her arms above her head and her legs stretched. They moaned and squirmed as the cocks were very warm against their skin and actually sturdy enough to even stop super-strong Knees from moving. Two cocks moved to their nipples and jammed themselves inside them, causing both to moan loud and open their mouths which allowed a tentacle each in their throats, and finally two more cocks jammed in their ass and pussy, making them moan and gurgle in the cocks in their mouths.
“Time for some more adult fun…” the two Shadows chuckled and their cocks started thrusting in the two girls, who had never felt such a thing in their life and yet they weren’t regretting it, not even Knees could be against it. The tentacles gently held them and groped them while they thrusted fast and rough in their holes yet without causing any harm to them and Shadow was surely enjoying this. Not every day he’d get to enjoy such killer bodies all at once and he wasn't going to let this situation go to waste.


The two clones fucked the girls silly for a long time, both girls couldn’t seem to have enough and started to think that they needed more dick in their life even though they were lesbians. The cocks started throbbing as they hit the 15 minute mark, signing that Shadow was close. After all, the serums took a great toll on his stamina and he had been pushing himself a lot, but now even he had reached his limit. He showered their bodies with cum while both clones gritted their teeth and both girls moaned and arched their back as the sticky cum rushed into their every hole, then the tentacles settled them down and returned to be one simple cock, followed by the clone vanishing and Shadow having to take a sit to catch his breath. For a few minutes, the only sound in the house was that of their breath and moans.
“Well, isn’t this cute?” asked a voice which made all three of them jump and look who was: both Amy and Rouge were looking at them from the entrance hall of the girls’ house and both looked completely MILF with their grand curves, especially Rouge’s.
“How… Long have you been watching?” asked Shadow, blinking.
“Hm, I guess since you started to fuck Knees. Me and Rouge met and decided to come see them, that’s when we saw you. We got curious and peeked, and found out that our little girls have become so much more enterprising...” Rouge giggled.
“Moooooooom…” Knees whined. Then both Amy andRouge took off their clothes, showing that they had no underwear to contain their massive curves, probably because no one could manufacture something to contain them.
“And we got horny for some good old fashioned ramming.” Said Amy, biting her lip as she was horny “Don’t worry, our dear hubbies told us that our marriage is open when it’s about sex. The more the merrier, right?” she added, giggling and making her boobs jiggle freely. That alone was enough for Shadow to grow hard again and pounce on the ladies, using the twin cock serum to fuck both while he groped, spanked and sucked on their luscious breasts, making them moan loud in pleasure as they told him how much they missed this.
Sarah and Knees watched the sex unfold with widened eyes: their moms were that horny? That… actually explained a lot. The two girls just watched, too tired for anything else, until they decided to make out gently to calm themselves while the adults had fun.


Shadow came in the MILFs four times in the following half hour, being that it was them and not the girls he could go all out with them and be as hard as he wanted to since Amy and Rouge could take it. The women screamed in bliss as he fucked their pussies at the same time and flooded their womb with his cum. Finally, his dicks returned one and he laid on them, panting as he was completely worn out. Sarah and Knees stopped kissing and crawled to them, laying on his back as he now was surrounded by four pairs of boobs, which made him coo and wag his tail.
“Thank you, Uncle Shad, for showing us…” cooed Knees, smiling.
“Mmmm… I think we’ll need to do this again…” cooed Sarah, purring tiredly.
“Don’t tell me my cock made you straight…” Shadow huffed. The two girls looked at each other and smiled.
“...NAAAAAAAH!” they said together, then they started laughing, followed by Shadow, Amy and Rouge.


THE END.
