Chapter 26

There are few simple pleasures in life greater than waking up with a beautiful woman in your arms. When that beautiful woman is your soulmate and partner in life, it’s even better. Sadly, it’s an experience that many unfortunate souls will never get to have. Even fewer can have the experience, and claim that their other half is a powerful sex genie who can grant wishes and make you one of the most powerful humans on earth.

As if all that wasn’t enough, add the feeling of two greedy mouths sucking on your balls. That’s how I woke up. With Amara pressed tightly against my side, her head resting on my shoulder, and the twins laid between my legs, each with one of my heavy, cum filled balls in their mouths.

Elsa was on my left, while Elsie on my right, as they gently sucked, licked, and kissed my balls. I was considering feigning sleep, when a small groan escaped, unbidden, from between my lips. Two sets of eyes, one pair a sparkling sapphire blue, the other an enchanting emerald green, flicked up to look at me.

“Good morning, bro.” They said in perfect harmony, their ruby lips and pearly white teeth giving me dazzling smiles.

“Hey girls, it most certainly is,” I replied sleepily.

They each wrapped a hand around the thick, veiny shaft and started to slowly stroke my cock. Even with their second overnight growth spurt where they grew a further three inches, their hands were still too small to wrap all the way around my girthy cock.

“You’re right, Elsa, it is bigger.” Elsie cooed excitedly, before leaning in to plant a sloppy kiss on the head.

“I told you! And so did mom”.

Since adding the extra inch to the length of my cock, Elsa was the only one of the twins to experience its new size. She had sucked my cock clean in the back of the limo, after our Mom had ridden me to a mutual climax. Despite the extra inch, she had still managed to deepthroat me with ease.

“She told you?” I asked as Elsa copied her sister’s action, kissing the head.

“She didn’t really have much of a choice. We found out what you did to her when we went shopping for new bras yesterday. Boobs don’t just grow a whole cup size overnight.” Elsie said.

I raised an eyebrow and looked pointedly at her own chest, which was straining the tight pink shirt she had slept in.

“You know what I mean! Boobs don’t grow that much unless you have a pervy big brother with magic sex powers,” she said, rolling her eyes.

“Admit it. You love having a pervy big brother.” I teased.

Rather than answer me with words, she lowered her head to my cock and slid her lips down until they reached her fist, which was stacked above her sister’s, about halfway down my shaft. Even with one hand each on my cock, the fat head still was still able to reach the back of her throat.

“Her tits leaking milk was a little sus too, bro” Elsa said, to which Elsie moaned her agreement, her mouth too stuffed full of cock to speak.

My sisters switched positions with Elsa sucking my cock. Elsie moved her hand down to my balls, freeing up space and allowing her sister to take my cock into her throat. Even with Elsa’s hand still holding the base of my cock, there were still almost seven inches she could suck, three of which pushed into her throat, creating a small bulge.

“Besides, did you think we wouldn’t notice you’re suddenly taller than Mom, and like, a total hunk now?” Elsie said, sliding up beside me and running her hands over my chiselled physique.

She made a good point. Unlike Emily, Pip, and Lacey, my little sisters weren’t subject to any commands about accepting mine and Amara’s powers as unremarkable or insignificant. Mom, Laura, and the twins all knew the truth.

It made me wonder how others would react to not only my new appearance, but the twins’ too. Their growth was even more unbelievable than mine. Three weeks ago, when school let out for Christmas, the twins had been just 4’4” with little, half apple-sized, B-cup tits. Now though, while still shorter than average, they had grown a full seven inches taller, and their tits were nearly a D-cup in size.

Even ignoring the fact that they were just fourteen and already sporting tits larger than half the girls two years older than them, there was no way they should have grown so much in such a short time. Genies, magic, and wishes were unlikely to be at the top of anyone’s list of reasons to explain it, but I couldn’t think of a believable alternative.

I would have to worry about it later though, because any further thoughts in that direction vanished as Elsa removed her hand from my cock and crammed the entire prodigious length down her throat.

“Oh, fuck!” I swore softly, one hand moving to pin her head in place.

Elsa purred happily, her throat vibrating around my cock. I kept Elsa’s head pinned in place for a full three minutes to test the enhancement I had given my girls to allow them to breathe when their throat was stretched tight around my cock. Like all of the women in my family, Elsa was an expert fellatrix, and enjoyed giving head almost as much as I enjoyed receiving it.

Elsie was tracing the contours of my muscles, while softly kissing up the side of my neck. I turned my head and caught her lips with mine, kissing her softly and sweetly. She still had a slight taste of her peppermint toothpaste to her.

“So you can make it as big as you want?” Elsie asked when we parted, a sly smile on her lips.

“Yeah, pretty much.”

Elsa’s lips made a wet ‘pop’ as they slid off my cock.

“Really?! You gotta do it for us, Thor! Make your cock huge!” She pleaded, moving her hand back to stroke my now thoroughly lubricated cock.

Presented with such an articulate and compelling argument from my little sisters, I was left with no option but to acquiesce to their request.

“I guess that might be fun to try,” I admitted. Besides, I was interested to see what, if any, the limits of the ‘take any size’ modification were.

“Wait!” Elsie exclaimed.

“I want it inside me while you do it.” She said, wriggling out of her panties and swinging a leg over my waist, and reaching up to grab onto my shoulders.

Being a helpful sister, Elsa rolled to the side so her twin could shuffle back into position, and then guided my cock into Elsie’s wonderfully tight snatch. Elsa’s sloppy blowjob, and Elsie’s own arousal provided enough lubrication to make her descent onto me as easy as breathing. Despite the lack of resistance, it was still gloriously tight, and I couldn’t help but groan as the silken walls of her cunt spread around my cock, devouring over half my length in one go.

“Fuck Elsie, you’re so tight,” I groaned.

“Your cock is so big it already feels like it’s filling me up,” she moaned, lifting back up a couple of inches before sinking her weight down again.

I grabbed her hips as the head of my cock bumped against her cervix. Taking a deep breath and slowly exhaling, Elsie resumed her descent. The tiny entrance to her uterus resisted for just a moment, before spreading open and allowing my cock in.

“Fuck!” I groaned.

“Oh my god!” Elsie gasped.

With the extra inch, I was deeper inside her than I had ever been before. As her peachy little ass settled between my hips, there was already a very noticeable bulge in her stomach.

I felt some movement off to the side; my groan had awoken Amara, who smiled sleepily as she woke up.

“Hmmm, good morning, master,” she said, stretching out and kissing my cheek before she noticed my little sister impaled on my cock.

“A VERY good morning, it seems!” She corrected herself, her lips curling into a sexy little smirk.

“Hey Amara, Thor’s gonna make his cock massive inside Elsie!” Elsa said with an excited, yet oddly casual tone.

I found it strange, yet also super fucking sexy, the newfound casualness with which sex was discussed in my family. Elsa has just told my girlfriend that I was going to magically enhance my cock and fuck my underage, little sister like it was nothing out of the ordinary. She could have used the same tone and level of excitement to tell Amara I was taking them for ice cream.

After stripping naked and helping Elsie out of her top, Elsa straddled my thighs and acted as a support for her sister to lean back against. With her arms wrapped around her sister’s waist, she had her right hand lightly teasing Elsie’s clit, and the other gently massaging the bulge my cock created where it pushed out against Elsie’s stomach. I was so deep inside Elsie my cock was bumping into the very top of her womb. Her cervix felt like a second, extra-tight pussy deep inside her, and it was absolutely incredible.

Except for Esme, the succubus who owned Black Cat Curiosities, the twins were still the only girls I knew who could take my cock past their cervix. That had only happened after Esme had done the very same thing when she had pounced on me the last time I had visited her shop. Before that, I had never even considered it might be something I would enjoy; let alone whether or not it should even be possible. It occurred to me that with my new power, I could probably experience the same thing with any girl. However, despite how mind-bogglingly incredible it felt, I also liked the idea that it was something special that I shared only with my little sisters.

“Really?” Amara asked, sounding intrigued, before sliding down the bed to kneel beside my sisters, her hand joining Elsa’s over the bulge. Her tanned skin, a stark contrast to the snowy white of the twins’.

“I’m ready, bro. Do it!” Elsie said excitedly, rotating her hips a few times, the walls of her womb grinding over the sensitive head of my cock.

Three pairs of eyes, blue, green, and golden, locked onto mine, and all glowing brightly with anticipation and excitement.

“Go ahead, master. I too, am eager to witness the extent of your newest ability.” Amara purred seductively.

While the three of them had seen the results of what came from using my power, they had yet to see any physical changes manifest in front of them. As far as my length was concerned, I was already filling Elsie as deep as was possible without my powers having to rearrange body parts. While I was slightly curious about how my power would handle fitting a huge sixteen inches of cock inside a petite fourteen-year-old, I decided to focus on girth for right now.

Rather than immediately growing my cock to the thickness of a 2L drinks bottle, I decided to start off slow. Even before adding the extra inch, I had always been proud of the size of my dick. I knew I was already longer than most, so I had added the extra inch purely out of vanity. The girth of my cock however, was what really set me apart from most other men. Even the pornstars that catered to the ‘size queen’ or ‘monster cock’ genre of porn didn’t always compare favourably to my size.

Currently, Elsie’s delicate pink lips were stretched tight around my cock, clinging tightly and distending with every movement either of us made. Elsie rocked back and forth with small movements, shifting until the bump in her stomach disappeared, then back again. Each time she rocked back, the head of my cock slid through the crushingly tight channel of her cervix, before pushing back into her baking hot womb.

Rather than drawing directly from my reservoir of energy, I redirected a trickle of the energy flowing from the three girls in my bed.

“Oh God! I just felt it grow!” Elsie gasped, as I added a little mass, thickening my cock by an inch or so.

Leaning back against her sister and thrusting out her chest made her perky tits shake slightly. She moaned erotically as she rotated and twisted her hips, searching desperately for more pleasure.

“More! Make it bigger,” Elsie whimpered.

I added a little more, my cock thicker than a coke can now. The bulge in Elsie’s abdomen had increased to outline not only the rounded head, but the first two inches of my cock as well. Suddenly, Elsa gasped as Amara reached between her legs, two of her fingers curling up inside my other sister’s snatch.

Seeing my tiny sister’s pussy so stretched so tightly, with her belly bulging so obscenely, was one of the most erotic things I had ever seen. I had to pause for a moment and lock down my own need to cum.

Elsie whimpered and gasped as she started to properly ride my dick, sliding up and down the monster pole of cock meat. She lifted herself until the plum size head of my cock was just barely held behind her cervix, before sliding back down. The control she had over her movements, in order to avoid my cock slipping free inside her was impressive. Elsa slid her hands up to grab her sister’s bouncing tits, flesh spilling between her delicate fingers as she massaged her tits.

The talented fingers of my djinn were making Elsa moan and squirm behind her sister. As she became increasingly worked up by the fingers in her own snatch, she pressed herself firmly into her sister; Elsie supporting her as much as she was Elsie. Elsa buried her head against Elsie’s neck, muffling her moans.

“Bigger!” Elsie gasped, her voice cracking a little.

“Are you sure?” I asked, sure that her pussy was already stretched well beyond her natural limits.

“Please,” she begged, dropping down my cock and grinding herself against me with circular motions.

I pushed again, adding another two inches to my already impossible girth, stretching my baby sister’s insides in fantastic and absurd new ways.

Elsie screamed. Her entire body shook as her eyes rolled back in her head, and she slumped back into her twin’s arms. A powerful orgasm ripped through her body, her over-stretched pussy convulsing wildly around my cock. Her short, sharp breaths pulled her stomach in and pushed her chest out. Her tits strained in her sister’s hands, while her sunken stomach bulged out, showing where five inches of my cock was buried, deep inside her.

If not for using my powers to avoid cumming myself, that would have done it for a second time. When Elsie had recovered enough to support her own weight, Amara pulled Elsa to the bed, and they moved into an enthusiastic sixty-nine. Elsie leaned forward and kissed me, her sizable breasts squishing delightfully against my chest as we started to make out.

I began to slowly deflate my cock when Elsie broke our kiss.

“No, wait! Keep it big. I want to really feel it fucking me!” She said, her beautiful face just a few inches from mine.

I moved one of my hands up to take a fistful of her hair. She let out a small gasp at the sharp pain, but it seemed only to push her arousal higher, her pussy quivering and clamping down around my cock like a vise.

“Sounds like my little sister is a size queen for her big brother’s cock.” I said, stating the obvious.

I added the extra girth I had just removed, making Elsie moan again, her green eyes narrowing as she nodded.

“Say it” I said quietly but firmly, tugging slightly harder on her hair, making her moan again.

Despite Elsie’s position on top of me, having her body stretched around the monstrous shaft of my cock made me feel powerful, and dominant. Though it was usually more my mother’s role, I loved how my sister was giving up control of herself for my pleasure. It wasn’t like I was the only one enjoying this though.

“I’m a size queen for your cock! I love having my big brother’s magic dick so deep inside me. I’ll be a good little slut for this cock!” She said, taking my order and running with it.

I moved my hands to gently hold her cheeks.

“Good girl,” I said, kissing her smiling lips.

Sitting up, she wriggled her hips as if trying to find a comfortable seat, then leaned back slightly, reaching back and planting her hands on my thighs. She pulled her legs up and planted her feet on the bed next to me, putting her in a sort of squatting position over me. Leaning back like she was, not only exposed her obscenely stretched pussy, but the position made her stomach bulge even further. The fist sized head and six inches of my cock, thicker than my clenched fist, clearly outlined where it pushed against her insides.

Starting with just small movements, she started to slide her pussy up and down my cock. Her overstretched pussy lips distending with each movement of her hips. Elsie gasped and almost lost her footing when my cock fully pulled out of her cervix for the first time, before pushing back through again.

“Holy fuck, that’s tight,” I grunted, my head falling back.

“It’s so big! Elsa, it’s so fucking big!” Elsie moaned. Elsa made no response to that, other than to moan a little louder into my girlfriend’s pussy.

I grabbed hold of her ass to help support her, to prevent her feet from slipping out from underneath her completely. Her delectable little ass filling my hands. I started to thrust up into Elsie, matching the pace she set to let her stay in control.

“Oh my God! It feels like I’m being torn in two!” She whimpered as she once again forced my cock back through her cervix.

“Elsie, baby. If it’s too much, I can make it a bit smaller. You don’t have to-”

“Don’t you dare!” she interrupted me, forcing my cock as deep as it would go. The head of my cock punching out against her stomach as it rammed into the back of her uterus

“I love feeling so full of your cock. And being stretched so much hurts so good!”

I already knew that both Elsa and Elsie often enjoyed rougher sex, where the lines between pleasure and pain became blurred. Nothing quite to Emily’s level of masochism, but definitely enough to enjoy an unforgiving and relentless pounding, or stretching in this case.

“I guess we know that some of the enhancements I gave you two are working as intended,” I responded, referring to the changes I had made that would allow them to take all of my cock into any hole, no matter how large it was.

“Just fuck me, bro! Take your monster dick and break your slutty little sister!” was all she said through gritted teeth and pleasured grunts,

The twins dirty talk had really come along recently. Soon they would give Lauren a run for her money. Our older sister was still one of the more vocal girls I had fucked.

Elsie showed amazing stamina and finesse as she bounced on my cock. Her muscle control due to a combination of her athleticism from almost a decade of ballet, three years on the junior cheer squad, and the enhancing effects of my cum. Even without the effects from my magical cum, her slight frame was deceptively strong.

Her tits bounced on her chest and loose hair whipped around as she now rode the full length of my massively engorged cock. Even seeing it before me, it was hard to believe. As she rose up until just the tip was still inside her, the absurd proportions of my massive cock were revealed. It was longer and thicker than her entire forearm; her clenched fist was smaller than the head. ‘Size Queen’ was just one of the many hats the twins wore in regards to their kinks, but this was next level. I bet I could make a fortune if I went into porn with a sixteen inch long, super thick cock, with endless, massive cum shots.

Seeing it disappear inside her petite body looked like an impossible challenge, but she managed to pull it off, over and over again. Elsie was properly bouncing on my cock, acting as if its ridiculous size was of no consequence. The force with which my cock rammed against her insides and forced up her stomach almost hurt. The hardness of my cock fighting against the lightly defined six pack that showed the twins dedication to their ballet and cheerleading. Still, my balls felt like they were on the verge of exploding, and the pressure building at the tip of my cock was nearly unbearable.

Unable to resist cumming inside my sister any longer, I pulled Elsie down to my chest and held her in my arms as I released the hold I had on my climax. I think I might have briefly blacked out as my massively oversized cock erupted inside Elsie’s womb. I could feel my cock pulsing against my stomach through Elsie’s as the build-up of several orgasms worth of cum poured into my sister.

“Oh my God, I can feel your cum filling me up! It’s so hot!” Elsie cried as shot after shot of cum blasted into her.

“It’s all for you, little sister.”

“You’re filling me up, bro. Give me all that baby making jizz. Make me pregnant!”

“Yes Elsie! My sexy little sister’s gonna carry our baby!”

The twins in particular got off on the idea of getting knocked up by their big brother, and I couldn’t say the thought didn’t turn me on as well. The thought of my twin little sisters both carrying my child, with their bellies round and their tits full of milk, was incredibly hot.

With each gush of burning hot cum into her womb, I reduced the size of my cock. Just as the last dregs of my cum packed her womb completely full, my twitching cock was back to its normal girth.

I left my cock inside deep inside her, plugging her cervix and trapping all my cum in her womb as her body began absorbing the magical fluid. Elsie had fallen quiet, her heavy breathing steady as she lay on top of me. We would both need a few minutes to recover from such intense climaxes. I couldn’t be 100% sure, but I thought I felt her stomach slowly shrinking from curved to flat, as if her cum packed womb was actually causing her to appear slightly pregnant. I found the idea of her stomach physically bulging from the sheer amount of cum filling her womb wildly erotic. If I was only imagining the feeling of Elsie’s swollen stomach slowly shrinking, I would definitely enjoy trying to fill her with enough jizz to guarantee it would actually happen.

After a few minutes, during which a fair amount of the load stuffing Elsie’s womb had already been absorbed, she started to move again. Slowly and a little gingerly, she sat up, gasping as her change in position ground the head of my cock deeper into her uterus.

“Are you okay?” I asked.

Holding onto her hips, I pulled myself up until I could sit back against the headboard, with her still impaled on my shaft. With the differences in our heights, the top of her head only just reached my chin.

“That was amazing,” she whispered, resting her head against my broad chest.

“I was stuffed so full of your cock...” she trailed off, failing to find the right adjective to describe how she felt.

“Yeah...” I replied, resting my chin on the top of her head.

“Thor?” she asked after a couple of minutes.

“There was something else Elsa and I wanted to ask”.

At the mention of her name, Elsa disentangled herself from the post orgasmic make-out session she was enjoying with Amara and joined her sister in resting against me, her hand finding Elsie’s. I had been so focused on Elsie; I hadn’t even noticed their own climax. Maybe climaxes was more accurate. The twins’ sex drive rivalled mine and Amara’s, so I doubt they stopped at one.

“We want to be like mom. We want to have milky tits too,” Elsa said, looking surprisingly contrite, as if sorry for asking.

It was odd to see my normally bold and energetic little sister behaving in such a way. I gently lifted her chin and leaned down to kiss her. She moaned and melted into the kiss, pressing her nubile young body against mine. Her lips still tasted like Amara’s pussy.

“Is that what you want too?” I asked Elsie after breaking the kiss and turning to look at her. She nodded enthusiastically, bouncing on my cock a little in her excitement.

“It was so hot drinking from mom boobs. And her milk is, like, totally delicious!”

Elsa nodded vigorously in agreement.

“Admit to Thor. You find the idea super hot too! Your cute baby sister’s tits full of warm, tasty, milk.” Elsa said, pushing her tits against me.

“I felt his dick twitch inside me,” Elsie giggled.

Rather than say anything, I let my actions speak for me. Leaning down, I sealed my lips around one of Elsie’s small pink nipples, applied the flow of power and sucked. It took a little more power than with my Mom, since Elsie had never lactated before, but was much quicker with the use of the lactation ‘add-on’ pack I had created. A warm stream of milk flooded my mouth and Elsie gasped, her snug pussy quivering around my cock.

Her milk had that same thick and creamy consistency as our mother’s, but was slightly sweeter. It was delicious and I could immediately feel it revitalising me and filling my stomach with warmth.

“Ohh, Elsa! He’s drinking my milk”. Elsie gasped.

Reluctantly pulling my lips from Elsie’s boob, I pulled Elsa up next to me and did the same to her. Her milk tasted identical to her sister’s, and her own gasp matched Elsie’s as well. I switched back to Elsie while Amara pounced on Elsa, dragging her down to the bed and started drinking from Elsa’s tits. It was a little awkward sucking Elsie’s boobs, given our height difference, but it was more than worth the slight discomfort.

Unlike what I had done with Mom, I had tried to keep their tits mostly the same size. They got a little heavier and a bit fuller, but refused to sag under their extra weight. A quick check with my powers told me that my little sisters were now the proud owners of D-cup breasts. They hadn’t been far off the mark prior to this, so they should still be able to fit into their clothes.

I was enamoured with the twins’ breast milk. Every mouthful of Elsie’s sweet milk made my cock throb as the taste burst across my tongue. It had a slight nutty flavour to it, almost like almond milk, and some sweet notes that reminded me of melon. Elsie moaned and whimpered as I drank from her, grabbing fistfuls of my hair and clutching my greedy mouth to her chest. I switched breasts a few times, sharing a mouthful of her milk with Elsie each time I did so. Elsie slowly rode my cock as I greedily drank her milk. She used the incredible control she had over her petite body to bounce and gyrate her hips along my shaft while keeping her chest steady.

After what felt like it could have been an hour, but was probably only a few minutes, Elsie slowly lifted herself off my cock. Her flooded womb seemed to have already absorbed most of the cum I had pumped into her, and I briefly wondered if her body had absorbed my cum faster to counteract any possible negative effects of being so impossibly stretched. If so, it worked. She was positively glowing and no worse for wear. Even after stretching around my immensely girthy cock, her pussy had gone right back to being just as tight as before.

With my dick being free, Elsa wasted no time and quickly mounted my cock. I groaned in pleasure and threw my head back against the headboard when I felt her tight slit engulf my cock. Just like her twin sister, I filled her pussy completely and speared through her cervix into her womb, even with my cock back to it’s regular size. I hit against the back of her fertile centre every time she slammed her hips into mine, forcing up her stomach. She rode my thick, veiny shaft with such ferocity that it was impossible for me to catch a nipple with my mouth. Her new D-cup boobs bounced and shook wildly with her movements, drops of milk hitting us both. The extra weight of her milk made her tits hang just a touch lower, giving them a larger range of motion, which added to the bounce and swing of her perky tits. I loved it.

Elsa was chasing an orgasm that had been building while Amara sucked her tits with the same enthusiasm I had been sucking on Elsie’s. It only took about five minutes until her efforts bore fruit. She slammed her hips down and I went off inside her womb like a bomb. I blasted one of my usual titanic loads into my little sister, and was finally able to bring my sucking mouth to her leaking breasts.

I leisurely sucked her tits as she came down from her climactic high, and just like Elsie, shared her delicious milk with her. After all, Mom had taught me to share with my sisters, and I was nothing if not a good big brother. The restorative properties of her milk mixed with the cum I just filled her with, would have her back to her normal perky self before school started.

“Girls! What are you doing?” I heard mom call from the doorway, a silk robe wrapped around her body.

“I told you to wake Thor up with a blowjob! I didn’t say you could spend almost an hour having sex!”

“Well, we did wake him up by sucking his cock,” Elsa said with a cute little giggle, from where she sat still impaled on my dick.

“Yeah, and you didn’t say we couldn’t fuck him. Just to wake him up with a blowjob, which we did!” Elsie added with a mischievous smile.

Mom opened her mouth to reply, but stopped short and just sighed.

“Shower, now. Both of you.” She said to the twins, her voice stern.

Elsa pouted, but eased herself off my cock, which I swear made a popping sound when it pulled free of her womb. Leaning in close to my ear, she whispered,

“Stretch me out like that next?”

“Promise,” I said, locking my little finger with hers in a pinky swear, and giving her a quick kiss.

Elsie came in for her own last kiss.

“Thanks bro, that was amazing. I can’t wait to try that up my butt!” she said with a cheeky wink.

In her ass! I tried to imagine what it would look and feel like but even enjoying my post nut clarity, my mind wasn’t up to the task
