Chapter 35

“Aaaaggghhh!” Pip screamed as her fifth orgasm tore through her, before she passed out from the overload of pleasure.

She was face down, ass up, with her legs hanging limply off the edge of the bed. Both of her holes were leaking my cum, the viscous white liquid slowly working its way out around the base of my cock to drip down her legs. Next to her on their bed was Lacey, the younger blonde slightly more coherent than her girlfriend. Seeing that I was done with Pip, Lacey crawled over to us, staring up at me through half-lidded eyes. Leaning over Pip’s dynamite ass, she wrapped her small hand around the base of my shaft and pulled my cock out to where she could take it into her mouth.

“Mmmmm” she moaned as she slowly but steadily swallowed my cock whole, her tongue swirling around as much as she could manage with her mouth being so stuffed.

When she had taken my full length into her mouth and throat, she flicked her bright blue eyes up to meet mine. Then, she slowly backed off my length, her lips sealed tightly around the girth of my shaft, cleaning off every last trace of my jizz as she went. When she reached the tip, she stopped and ran her talented tongue around the sensitive head a few times before releasing me from her hot little mouth.

“Aaahhh” she let out a satisfied cry before diving face first into the twin fleshy pillows of Pip’s butt, her tongue scooping up any trace of cum that it could find.

Seeing that I was no longer needed here, I grabbed my clothes from where I had dropped them on the floor and made my exit.

“Well it looks like Pip is in good hands, so I’ll leave you to it then. Goodnight Lacey” I said on my way out the door, receiving a muffled reply that sounded like it could have been a “‘night Thor” in response. Closing their bedroom door behind me, I set off in search of my own girlfriend to spend the night with.

While I had been busy making good on my promise to Pip, Amara had taken the opportunity to have her own little threesome, showering with the twins before moving to their bedroom to enjoy some quality time with the two teenage nymphomaniacs. After so much sapphic indulgence, they had to take another shower, Amara choosing to indulge in the twins’ soaped up bodies over her instant-clean trick.

I don’t blame her for her decision. Given the choice, I would certainly choose to shower with Elsa and Elsie, and enjoy the wonders that came with having my slutty younger sisters rub their hot little bodies against me. Amara’s ability to instantly clean us up was a godsend, but sometimes it was nice to just stop and smell the roses. Or, in this case, fuck your little sisters.

I tried to tempt Amara into taking another shower with me, but it was getting late, and she was hungrier for dinner than for dick. So, I had a quick, solo, cold shower, and followed my genie girlfriend into the dining room, where Mom, Laura, Lauren, and Emily were already sitting around the table, dressed in silk bathrobes, with their hair in various stages of drying.

“Hey Thor, what did Pip do to earn that much spanking?” My older sister asked, smiling mischievously at me over the rim of her wine glass.

“You heard that, did you?”

“I’d be surprised if they didn’t hear her in the Lobby!”

I just gave a wry smile in lieu of an answer before ordering room service for everyone, and joined them at the table. Less than five minutes later, the twins joined us, and immediately noticed that there were three pairs of boobs that were all noticeably bigger than they had been when we got home. It didn’t take much for the pair to put two and two together, and figure out that I was to blame.

“Lauren, Laura, and Emily too!” Elsa exclaimed.

“Seriously, are you trying to start a dairy farm or something?” Elsie added.

“Hey, who are you calling a cow!?” Lauren exclaimed in mock offence, earning a small chuckle from our mother.

While my sisters boisterously bantered about the big bouncing boobies their brother had bestowed on the bevy of beautiful busty babes he banged (try saying that five times fast) I noticed that the twins were actually slightly put-out by this development. Being able to lactate had made them feel special, and while they didn’t mind sharing that gift with our mother and older sister, adding Laura, Emily, and possibly Pip and Lacey in the future, took away from that feeling and made it a little less special.

“Don’t worry girls,” I said, pulling the twins into my lap, groping each of their breasts in the process.

“You’ll always be my special little milkmaids.” I reassured them, which earned me a big kiss on each cheek from the giggling pair of petite, busty blondes.

We chatted amicably while we waited for the food to arrive, which it did about fifteen minutes later in the form of a cart piled high with food. The twins were reluctant to leave their seats on my lap, electing to stay where they were and feed me themselves. They also insisted that I drink their breast milk instead of the soft drink I had ordered, which didn’t take much convincing on their part. I think it was more for them to reassure themselves they were still just as special, even though others now had the same milk enchantment.

Lacey joined us briefly to fill up two plates for her and Pip; the older blonde still a bit too sore and out of it to make it to the table. I did a quick check on Pip, and found only a pain like what you get after a heavy workout. She would be right as rain before long, thanks to all the cum I had pumped into her holes. Just to be sure though, I asked Laura if she could provide a glass of her breast milk to help the recovery process along, and was quite entertained when she opened her robe, bent over, and asked to be milked like a cow.

We all had a good laugh before she said that she was finished anyway, and followed Lacey to give Pip a milky pick-me-up directly from the source. The meal and conversations gradually wound down from here, everyone having eaten their fill. After our various sexual exploits, and big meal, it was getting fairly late, so we didn’t hang around much and instead called it a night. I noticed that the twins followed our older sister and Emily into their room, identical eager grins plastered to their faces.

“I thought about what you said about the twins. I thought maybe spending some time ‘bonding’ with their sister would be a valuable experience for them.” Mom said before kissing me and Amara good night.

“Bonding over bondage, I like it. If they have any sort of Dominant streak in them, Lauren will find it and put it to good use.” I would definitely have to get all the juicy details tomorrow.

Returning to the master bedroom, Amara and I made love until it was past midnight before falling asleep in each other’s arms. As I drifted off to sleep, I felt soft waves of excitement, arousal, and pleasure-filled pain coming from Lauren and Emily’s room.

Definitely something I would need to hear about in the morning.

As had become part of my normal morning, I was woken up by a pair of lips wrapped around my cock. Today’s skilled fellatrix was Lauren: my beautiful, busty, and now lactating older sister.

“Hey Lauren.” I mumbled through a fog of sleepiness as I stretched, crossing my legs loosely behind my sister’s back as I relaxed onto the soft mattress.

“Hmmm, morning Thor,” she replied, my cock popping from her lips.

“Sleep well?” She asked, stroking my cock.

“Yep. You?”

“Okay. The twins spent most of the night driving Emily crazy.”

I was struck and amused by the absurdity of how my sister and I could make casual small talk, while she was between my legs and stroking my cock.

The conversation dropped off as my big sister returned her lips to my throbbing morning wood. The blowjob that followed was similar to our brief conversation in that it was oddly casual. It felt amazing, don’t get me wrong, but the way she went about it was more like she was just doing an everyday normal task like cleaning her teeth, or making her bed. There was no raging sexual heat in our actions, no feverish, lust-driven rush to orgasm.

It was just a sister, helping out her brother. A naked sister, helping out her naked brother by giving him a blowjob, but just helping all the same.

After working my cock with her tongue and the tight embrace of her throat, she slipped her mouth off my cock, letting it fall to my stomach with a meaty ‘thwack’. Licking up a drop of pre-cum from her lip, she crawled up my body to straddle me, sliding her moist slit over my shaft a few times.

Grabbing my erection in one hand, and resting the other on my chest for balance, she rose up on her knees before sinking down and taking all nine inches into her warm and wet pussy, hissing in pleasure all the way to the base.

“So they did well?” I asked, picking up where our conversation had left off, gently holding her hips as she casually rocked back and forth.

I could feel she was enjoying herself, and I was certainly enjoying the sensations her tight, squirming pussy was giving to my cock. While we may have been acting casual, there was nothing casual about the way our sexes ground into each other. The tip of my morning wood repeatedly bumped into her cervix, and the walls of her pussy were madly fluttering over the massive invader.

“Uh-huh, they’re both Doms for sure. Mmmph! They haven’t quite figured out exactly what kind of Dom yet, but they’re definitely more than just curious”. She said, biting her lip and stifling a small moan.

I slid my hands up over her curves and squeezed my sister’s new, milk-filled DD’s, a small stream of milk squirting out from each pink nipple. Lauren’s body locked up as she moaned in pleasure and mashed her hips down into mine, her arousal spiking sharply. It was the first significant reaction to anything we’d done since she woke me up.

With my fingers digging into the soft flesh, I pinned her in place on my cock and shuffled myself back so I was sitting up against the headboard. Lauren mewled cutely as my movements stirred my cock around inside her, her pussy rippling happily around me. From beneath the covers next to us, Amara let out a soft sigh, lifting her head slightly and squinting at us blearily. The corner of her mouth curved up a bit when she saw my sister and I before rolling over and falling asleep again. Despite the fact my bond with her reduced my need for sleep by about half, Amara herself seemed to require a full night’s sleep. Maybe it was just a preference rather than a need, but the end result was the same.

“So I’m guessing that Emily and the twins are still sleeping?” I asked as she began to buck, twist, and rotate her hips beneath my hands, scrambling her insides with my dick.

“Emily was still asleep last I saw, and the twins were sucking on her tits when I left.” She answered, adding small bounces and undulations to her movements, and wrapping her arms around my shoulders.

“Great minds think alike,” I quipped, before ducking my head slightly and sealing my lips around one of Lauren’s nipples, suckling greedily. Immediately, my mouth was flooded with my older sister’s sweet, creamy breast milk.

Lauren moaned, her arousal spiking with every mouthful of milk she expressed. Her movements quickly grew more frantic and driven by lust, rather than the casual intimacy we had been enjoying up to this point.

“Oh, fuck! I never thought I’d ever feel like this! I still can’t believe you never told me that Mom and the twins lactate like this,” she gasped, her hands knotting themselves in my hair and holding me to her breast.

With a meaty ‘smack’ I grabbed hold of and squeezed her wonderfully round and toned ass, kneading her cheeks, helping her movements along as she worked her tight snatch over my meat.

Taking a break from being breastfed by my sister, I looked up and gave her a quick kiss. “I was hoping that you’d find out on your own eventually, maybe in the middle of some mother-daughter or sisterly bonding time,” I said cheekily.

Lauren’s only response was to stick her tongue out at me, before she ground her ass into my lap as hard as she could, mashing the head of my cock into her cervix, causing her to groan lustfully.

“Well I guess it worked out in the end,” she said a little breathlessly, shoving her big tits into my face, the big fleshy globes smothering me in squishy, jiggly goodness. Not one to pass up the opportunity to play with my sister’s tits, I immediately started motorboating her, earning a small giggle from Lauren.

“There is something you can do to make up for it though,” she said as she continued to grind my dick as deep into her as it could reach.

“And what would that be, exactly?” I asked, lifting her up by her ass and dropping her back down into my lap.

“I want to try the other impossible thing you did with Elsa and Elsie”.

“I mean, it’s not technically impossible, your bodies are already set up to be able to produce milk. As long as you took the right hormone supplements you could-”

Lauren silenced me with a kiss, her breasts pressing into my chest. She pulled away, her face just inches from mine.

“You’re missing the point. I want you to stick your huge dick so deep inside me that you’re fucking my uterus” she said, looking at me face to face, excitement, desire, and curiosity flashing behind her bright green eyes.

With a flurry of movement, I rolled us over so I was on top, lacing my fingers through hers and pinning her arms above her head. Her dark hair with its purple highlights fanned out around her face as she landed on her back with a huff.

“Are you sure?” I asked.

She nodded, the motion causing her boobs to jiggle distractingly on her chest.

“I had never even considered it, because it’s supposed to be impossible. But now that I know it’s an option, I want to try it!” was her excited answer, her body wriggling beneath me.

“Fuck me little brother. Shove your massive cock so deep inside me that I can taste it.” I’ve said before that I had a soft spot when it came to spoiling my sisters, and I saw no reason to change that now.

“Oh, you’ll taste it all right. Get ready Lauren, because you’re about to get it,”

At its normal size, my cock was already stretching out her pussy and pressing against her cervix, so I drew back a little bit before lengthening it slightly, and bottomed out in Lauren’s juicing pussy again. I kept this up, slowly increasing the length of my cock, the pressure against the tight ring her cervix continually building. Unlike with our younger sisters, I consciously made the change to allow her cervix and womb to stretch and accommodate my cock without suffering any lasting damage.

Elsa and Elsie had felt a little put out that I had given Lauren, Emily, and Laura the breast milk enhancement on top of them and our mother. With more of my harem lactating than not, it made them feel a bit less special. With that in mind, it might be best not to tell them about this. Cervical penetration was something I had only shared with them, and Esme, until now. Without the same anti-jealousy commands that the rest of my harem had, doing it with someone else might hurt their feelings. Maybe they would be okay sharing the ability and experience with their older sister though. I sure hoped so.

Lauren was gasping and squirming, her body twisting and shuddering beneath me as the pressure against her cervix reached critical mass.

“Last chance” I said, my cock only a small shove away from pushing inside her previously untouched depths. Lauren had taken my virginity, but by that time had long since had all of her major ‘firsts’. Now though, I was in a position to return the favour and take one of her firsts myself...

Lauren just nodded, not trusting her voice to be steady enough to actually form words.

Staring into Lauren’s intense green eyes, I withdrew nine of the ten inches of my cock from her, leaving only the fat head inside her slit. As I pushed back inside, I added two more inches to the length of my cock, figuring now was as good a time as any to see how far I could go with my second power. My sister’s ample chest heaved as I speared her with a foot of solid dick. There was a brief pause as I reached the spongy ring of muscle guarding her fertile centre, then she shuddered beneath me as her cervix relaxed, and the head of my cock pushed into her womb.

Lauren came instantly. Her eyes rolled back in her head, her lips parted, forming a perfect ‘O’ shape, but no sound came out. Her pussy went wild around my cock, pulsing, convulsing, shuddering, fluttering, and vibrating in fantastic ways. I nearly blew my load then and there, barely able to hold myself back from exploding inside her as I came to rest with my foot long dong buried deep within my big sister.

I stayed completely still, holding myself inside her as she lost nearly all control of her body beneath me. The sexual energy flowing from her was the most intense I had ever gotten from her. I lay down on top of her, groaning in pleasure as my weight crushed her into the bed, my head sagging down and resting next to hers.

“Deeper,” Lauren moaned softly into my ear a moment later.

I lifted myself up off of her a little and raised an eyebrow at my sister.

“Just a little deeper ... I can take it, now fill me,” she panted, her eyes wild with lust.

I pulled back until her cervix was stretched tight around the glans of my cock, before pushing back into her. I continued to thrust into her, gradually lengthening my shaft until I finally started impacting the very top of her uterus. I knew I was beyond any reasonable approximation of realistic dimensions, but I didn’t care. Lauren’s insides felt incredible, and she clearly felt the same way about my magically enhanced meat.

“Oh my God! I can feel you all the way up inside me. This is impossible and I love it!”

I took one of her hands and guided it down to her stomach, right over where my massive cock forged a lump in her otherwise flat abdomen.

“And what about this? Feel this too?” I asked, rotating my hips so she could feel it moving beneath her hand.

Lauren just moaned in a mix of disbelief and arousal, any of the casualness from earlier long gone. I sat up onto my knees, my hands moving to take hold of my sister’s small waist when a dainty, dusky hand slid over Lauren’s pale stomach. Amara rested her hand atop Lauren’s over the large bulge formed by my cock.

Amara leant up and kissed me.

“Good morning, master.” She purred, Lauren moaning softly with every small movement we made.

Amara leaned down and shared an equally passionate kiss with my sister before moving down and sealing her lips around one of Lauren’s erect nipples, and began sucking enthusiastically. I pulled my hips back, the head of my cock slipping free from her cervix before pushing back past the crushing ring of muscle again. My cock was so long now that I was only able to withdraw a little more than half of its ridiculous length without shuffling myself backwards.

Lauren wrapped a hand around Amara’s head, holding my girlfriend to her breast as she moaned, swore, and panted like a bitch in heat. The sensation of pushing in and out of Lauren’s womb was fantastic. The dual stimulation of her pussy stretched around my shaft, and the crushing tightness of her cervix was like fucking two pussies at once.

It was fucking amazing!

“Oh fuck Thor! You’re so fucking deep!” my sister exclaimed.

“Uummph! Damn your tight Lauren,” I grunted back at her.

“You like feeling my cock in your womb?”

“Yes! I love it! I’m so full” Our mutual declarations of ecstasy were cut short when my sex genie girlfriend finally moved on from my sister’s milky tits.

I continued hammering into Lauren’s baby pot as Amara shared a milk-filled kiss with Lauren and then with me. As I tasted her milk, I had to fight my growing need to cum, trying to prolong the incredible experience. It was a futile endeavour however, for just then, Lauren started stammering frantically.

“Oh fuck! I’m gonna cum! ImgonnacumIImgonnacum! Aaaaagh!”

Lauren locked up and let out a near ear-splitting scream as she came again, the trembling spasms of her insides pushed me over the edge. I felt my balls clench, my cock throbbed and pulsed, the pressure growing until it burst as I hilted my impossibly huge cock deeper inside Lauren than any normal person could possibly imagine. Thick, fiery hot cum erupted from my cock, flooding my sister’s womb with my seed. My vision blurred as I painted her insides and absorbed more sexual energy from Lauren than ever before. I came and came, jizz continually pumping from my shaft in massive spurts, filling my sister beyond what should have been possible.

“Oh fuck Lauren! Take that jizz!” I managed to spit out through the haze of pleasure and lust.

“Yes! Cum in me Thor! Cum in your sister and breed me! I’m your little slut, fuck!” she screamed back at me, her legs snapping closed behind my back, holding me as deep inside her as possible.

It seemed that the whole breeding fantasy was a common trait among my sisters, and I definitely wouldn’t be complaining any time soon; it was hot. I also loved the fact that even Lauren, who was probably the most dominant girl in my harem, still submitted to me in bed. It was the same with Mom. Normally, she was the boss, but as soon as my dick was involved, she was all mine.

Lauren was delirious with pleasure by the time I stopped pumping her full of cum, her legs releasing me from their grip and dropping limply to the bed. Looking down at her, there was a slight bulge to her normally flat tummy. ‘So I wasn’t imagining it the other day’ I thought to myself, remembering the wakeup call that the twins had given me. One of these days I would have to measure just how much I actually came; it had to have been a huge amount if it could stretch my sisters like this.

I slowly started to pull out, causing Lauren to whimper as her sensitive insides valiantly tried to suck me back in and hold my dick in place.

“Oh my. Looks like someone had a lot of fun this morning” Amara said from where she lay next to my sister, as inch after inch of my cock appeared from inside Lauren.

Her cervix tugged at my fat head before releasing me, snapping shut behind it and sealing all the spermy goodness inside Lauren’s womb. I continued to pull out of her until I had to actually shuffle myself backwards to go any further. When the head of my cock finally pulled free from my sister’s pussy, it dropped down onto the mattress under its own prodigious weight.

The bed shifted as Amara crawled over and took my huge cock into her hands. Sixteen inches of impossibly enhanced man meat lay pulsing in her hands. ‘Maybe I overdid it a bit’ I thought to myself, my eyes flicking to where my sister was passed out in front of me. That line of thought was brought to an abrupt halt as Amara began to lovingly lick my cock clean of the incestuous mix of cum and juices. When she was finished, I returned my dick back to its normal size.

My gorgeous genie girlfriend led me into the shower, where she poured shower gel over her perfect breasts and used them to lather me up. By the time our shower was over, my balls were churning again, and the ever helpful Amara was only too happy to guzzle down my second load of the day.

Lauren was still passed out on our bed, and remained in that state while Amara and I dressed ourselves. I stuck to my normal jeans and tee combo, while Amara started with a matched set of pastel pink lingerie. She pulled on a tight black vest, followed by a black, sheer lace top.

“Black skirt or ripped jeans?” She asked me, holding up a hanger in each hand.

“Uh, the skirt?”

Amara thought for a few seconds, looking back and forth between the bottoms she was holding up, before she threw the skirt onto the bed and shimmied into the ripped denim.

“I love you Babe, but fashion just isn’t your strong suit,” she said, taking my arm as we headed out into the main suite, leaving Lauren to sleep off her orgasms.

In a stroke of luck, Emily, still completely naked, stepped out of her bedroom a few steps ahead of us. I slipped a hand around her waist and pulled her close.

“Good morning Master, do you need some help with your morning wood?” She asked quietly, as she groped my cock through my jeans.

“Not today, my naughty little slut; your mistress beat you to it. But she could probably use some of your tasty milk if you’re interested,” I replied, giving her a swat on her peachy ass.

“Yes Master!” She said with a gleam in her eyes.

The womb full of my cum and stomach full of Emily’s revitalising breast milk would soon have my ‘cum-atose’ big sister feeling right as rain before breakfast was even over. Speaking of breakfast, Amara and I had places to be...

The moment we finished breakfast, Mom hustled us out of the apartment and into the elevator to the lobby. After spending my morning with Lauren, and rushing through breakfast, Elsa and Elsie had again missed out on their morning serving of jizz. So the moment we pulled out of the hotel parking lot, my little sisters were tugging at my jeans.

Lacey and Amara had taken the two back seats, while I was seated between the twins in the middle row. Laura was riding shotgun, as she and my mom were going shopping after dropping us off. With all the breast expansions I’d been giving out, my mother had decided that it was probably not a terrible idea to just buy a few bras in multiple sizes, just in case I added to my ‘dairy farm’ as the twins had called it.

Back in the middle row, Elsa and Elsie had succeeded in extracting my penis from its denim prison, and had gotten straight to work. Working as a team, they teased me for nearly the entire forty minute drive to school. When we were only about five minutes out, they really stepped up their efforts, cramming as much of my cock into their hungry little mouths as they could manage. Their efforts paid dividends, and they were soon gulping down a massive load of my cum.

“Thanks bro!” They chirped in unison, kissing me on each cheek after licking my cock clean and tucking me back into my pants.

As Mom pulled into a parking space, the twins jumped out and dashed off almost before the car had fully stopped.

“See you all at three.” Mom said as the rest of us piled out of the car.

“Actually, I need to go see a man about a blonde after school.” I said.

“Ruby?” my mother asked, catching on quickly.

“Yeah, I decided maybe a trial period would be the best way to see if she and the twins can be more than friends. At the very least, after a week or two with us, she’ll learn just how submissive she really is, and what she wants to do about it.”

“And the fact she has been teasing you and every other guy in town over the past few years has nothing to do with it, right?” She asked with a knowing smile, before adding some classic parental advice. At least as classic as a parent could be when discussing getting your little sister’s a submissive best friend/sex toy.

“And you need to talk to your sisters about this,” Mom insisted.

“I will, I promise.”

“Make sure you do. Oh, and could you pick them up after their ballet class and walk them to the bus stop? It will save me a trip and driving here and back adds almost an extra hour and a half each time.”

I took Amara’s hand and waved as mom drove away, and we headed inside. I had a feeling that today was going to be a very interesting and educational day.

We arrived at our form class a few minutes early. Looking over at Miss Sif, the young teacher could have been mistaken for a student. I caught her eyes as Amara and I sat down. I saw a brief glimmer of desire in her eyes when she looked at me. A quick skim of her thoughts showed me that she had been dreaming of me every night this week, even when in bed with her girlfriend. So far, she had woken up feeling horny every morning since the orgy the first day back from holidays.

I had recently discovered than not only was Miss Sif bisexual, but she was in a relationship with the school’s guidance counselor, Miss Amber. When I asked my mother about it, she told me that she already knew. I was quite surprised, but then again, I was just her student, while my mom was her friend. Different types of relationships.

That wasn’t the only surprise though. It appeared that the pair of young teachers had an open relationship. They had sex with other people, their only rule was that they kept no secrets. On top of that bombshell realisation, I discovered that they played both sides of the field, going out to a bar or club and bringing home a different man or woman each. When they had started their relationship, it worked for them; they wanted to be together, but didn’t want to be tied down while they were young and adventurous.

Looking through her more recent memories though, it seemed that Miss Sif has grown out of that phase. She wanted to take their relationship to the next level and become exclusive. She hadn’t slept with anyone else, myself excluded, in several months. The one thing holding her back was fear. She was scared that if she shared her new feelings with Miss Amber, she might get cold feet and end the relationship; something she desperately wanted to avoid.
