Chapter 9

Within seconds of getting home, the twins came thundering down the stairs, both still completely naked.

“Thor!” Elsa said while launching herself from the third step, forcing me to catch her.

Elsa kissed me fiercely before letting go and dropping to the floor. I pulled Elsie in for a kiss who was slightly more tender and reserved than her sister, but no less passionate.

“Notice anything different?” Elsa asked.

She and Elsie stood next to each other. Both had their hands clasped behind their backs, chest thrust forward. It took me a second.

“Are your,” was all I got out before the twin’s excitement caused them to interrupt me.

“Our boobs are bigger! We’re taller too!” Elsie said.

“All that cum you filled us with made us grow bigger!” Elsa finished, spinning on her heel to show off her new body.

Their tits were noticeably bigger, and they were definitely taller. I focused on each girl, and their bubbles appeared.

Elsa James, 14, not a virgin Elsie James, 14, not a virgin.

Well, that was obvious. I made sure of that last part myself. Expanding their bubbles, I noticed several differences. Their bubbles were identical, as most things between them are. That wasn’t the difference I noticed. The difference I saw was in the information itself.

Yesterday, the twins had been 4’4”. Small, even for someone younger than their tender 14-years-old. At their age, they should be about 5 feet at least. If they followed my mother’s tall and slender build, as they did in every other aspect, they still had a lot of growing to go.

Unlike the twins, who are almost clones of my mother, Lauren and I took almost entirely after our father. Built like an Amazonian, at 5’11”mom had actually been an inch taller than my father. Lauren was short at 5’4” and at 20-years-old, unlikely to grow any further. At 16-years-old myself, I hoped to grow a couple more inches to reach 6 feet.

Despite taking after my mother, the twins are still below the size they should be. However, looking at their bubbles, not as much as yesterday.

I glanced at Elsa’s:

Height - 4’8” Weight - 41 Kg 28C - 20 - 24

Elsie’s was the same. The twins have grown a full 4 inches taller overnight. Their previously cute till B-Cups have grown into full C-cups. That was impossible. Then again, impossible summed up my life of late pretty accurately.

Could it have been purely my cum that had given them a growth spurt? I knew my cum provided certain benefits, but not to this degree. Was it a matter of quantity, or did being involved in the powering of my first cause this?

Something that worried me was that the twins had guessed my cum was the cause. Had they just been joking and accidentally stumbled across the truth? Also, why are they so chilled about it? Had they realised there was something a little different about Amara and me?

It was then I noticed something else unexpected in the twin’s bubbles.

Their health was perfect, and STI results were negative, as I expected. It was what was below that surprised me.

Relationship Status - Bonded Orientation - Bi-sexual - Polyamorous

Bonded? Amara had said we would become linked. Technically, the twins are the first members of my harem. I wonder what Laura’s and Pip’s bubbles would say when they arrived?

I expected the bi-sexual bit. They had been experimenting sexually with each other before our relationship became sexual. I wasn’t sure, however, if that bi-curious experimentation had been pushed to fully bi-curious by myself, or at least, our relationships. They certainly showed no hesitation in engaging sexually with Amara. I had realised they were messing around together. I hadn’t been sure that bisexuality extended beyond each other to include others before now. Maybe with Ruby or some of their other friends.

Polyamorous was a new one as well. However, their sexual relationship with each other, plus myself and Amara, did technically qualify. Plus, if my harem grew as Amara said it would, being at least partially polyamorous and bisexual would be a must. I’m not saying they would have to make a deeply meaningful and loving relationship with all the girls in my harem, but just be free to enjoy the sexual side.

“So, do none of your clothes fit?” I asked, due to their nudity.

Both girls’ eyes went wide, as if they hadn’t even considered that yet. With a quick glance at each other, they ran past me and shot upstairs. My brain refused to cooperate with my body for a moment as it replayed the last 10 seconds in slow motion, committing it to memory. The twin’s new proportions bounced and shook fantastically as they ran up the stairs.

With those images safely stored for later use, I headed upstairs to find Amara. I didn’t need to check each room, as I could sense her location. It wasn’t just her, either. I got a sense of the twins’ location and a general sense of their most dominant emotion.

For twins, it was excitement. It was slightly curious that they seemed to accept their unprecedented growth spurt. Teenage nonchalance or all part of Amara’s discretionary abilities? I assumed they extended to keep her abilities hidden but did that extend to cover me?

This morning has certainly been a learning curve but had also generated a lot of questions. My mind guided me to my mother’s en-suite and my sex genie, who was enjoying the shower. Unlike the bath/shower combo in the family bathroom, mom had a big spacious power shower. It was way better than the family bathroom one and much more accommodating to multiple occupants.

I stripped off quickly and slipped in behind Amara, wrapping my arms around her slender body.

“Hmm, good morning, Master,” she purred, pushing back against me.

“Good morning, my queen,” I replied, gently laying kisses up the side of her neck.

Amara spun in my arms, her hand coming up over my head as she pulled me down for a kiss. I felt that great volcanic eruption of love and passion I felt every time we kissed. The physical motions fairly simply, the emotional impact beyond words.

As was usual, it satisfied neither of us stopping at a single kiss. Five minutes later, I had her pinned against the shower wall, her legs around my waist and my cock buried in her pussy. It started slow and sensual, building off that kiss. But it quickly grew into a fevered and carnal expression of both our love and lust for one another.

Every thrust of my hips buried my entire length inside her tight, clenching cunt. Her tits bounced on her chest, her silky smooth bronze skin glistening wetly. The water of the shower hit us both, making our skin slick and hot. I was glad for the slightly roughened shower floor that let me keep my footing rather than pulling us both to the floor.

I shouted, and Amara screamed, both of us exclaiming our joint climax. My cock throbbed deep inside Amara as I pumped my rich jizz inside her. Her pussy writhed and rippled around my cock as she responded in kind, her cunt creaming around my cock.

I held myself inside her, our foreheads touching as we both caught our breath. Neither of us lacked stamina or strength, but an intense orgasm can leave you as breathless as a marathon. Even with the exhilarating rush of orgasmic energy rushing into me, I needed a moment to gather myself.

Eventually, I had to let Amara down. We both showered before the hot water ran out with only some gratuitous washing of particular body parts. Amara’s instant clean trick was useful, necessary even, but showering with her was much more enjoyable.

I was standing in front of the mirror, towel around my waist, trying to do something with my still-damp hair. I had been growing it out for the last six months. I was aiming for the sort of “artfully messy” kind of look. Some guys seemed to pull it off with effortless ease, even though they probably spent an hour every morning styling it.

I never got it quite right. The messy part I had down to an art. It was the “artfully” part I had yet to master. Amara stood just to my side, shook out her hair, and it went from dark and wet to dry and styled in seconds.

“Show off,” I playfully teased.

“I’m not just a pretty face,” she replied.

“True, you’ve got great tits and an ass to die for, too,” I said back and earned a flirtatious smile back.

“Keep it in your towel, mister! You need to tell me all about your morning and how your first wish manifested.”

We dressed first, which turned out to be an eye-opener for me. I went to my room and dressed as I usually would. Boxers, jeans and a t-shirt. Amara, deciding to dress as we humans do, headed to Lauren’s room.

It was a stroke of luck that they were very similar in size. Both busty, although Lauren’s D-cups were a size smaller than Amara’s double D’s. Luckily, Lauren’s slightly smaller bra didn’t seem to be much of an issue. Amara didn’t need to wear one at all, but on the occasions she chose to, they seemed to fit okay.

Otherwise, they had a similar slender build, and we’re not too far apart. I would need to take Amara shopping and get her own wardrobe soon, but this worked for now. Plus, with how frequently my sister changed her style, Amara had plenty of choices.

Since I only took all of 2 minutes to dress, I joined her in Lauren’s room. Reclining on the bed against the headboard, I was treated to the site of Amara dressing. Now, I thought the fun started when the clothes came off. They only went back on after said fun had been had.

However, I discovered that watching a girl dress, especially one as effortlessly sensual as Amara, can be just as enjoyable.

She started as you would expect with underwear. She settled on a matching red silk and lace set that worked with her skin tone. The way she moved her legs and ass as she pulled the panties up her legs had me hard straight away—the swell and shape of her breasts as she put on and adjusted the bra was just as erotic. Her tits swelled over slightly because of the size difference, but it still looked amazing.

Then she sat on the small bench at my sister’s vanity unit. Raised one leg and pointing her foot, she slowly pulled on a sheer stocking. The kind with the elastic hem. Watching her slide it up her shapely calves and thigh was even more erotic than her underwear. It gave her already silky legs look sleek and glossy.

I admired her perfect form as she took her time searching through my sister’s wardrobe. The skirt she chose was a cute pleated black mini skirt. Like the classic ‘naughty school girl’ style, it showed dangerous amounts of her silky smooth and toned legs.

Her choice of shirt was understated and straightforward, but she still made it seem sexy. Just a plain gunmetal grey vest that stopped a few inches above the navel, leaving a broad strip of her flat stomach bare. The stretchy material emphasised her bust, which, combined with her bare waist and slightly too small bra, proved a killer combination.

“Good?” she asked, striking a few cute, coquettish poses.

“Very good.”

She did a little strut from one end of the room to the other like a mini catwalk. Each step made her skirt swish just enough to flash the tops of her stockings. We both laughed at her little display. She looked stunning. Then again, Amara exudes sexuality. She could wear a grimy old potato sack to Paris fashion week and still be the star of the show.

Amara crawled up the bed and straddled my lap. Her hands rested on my shoulders while her ass pressed into my lap. She moaned and wiggled her hips, rubbing against my erection. I slid my hands up her stocking clad thighs and under her skirt to cup her ass.

“So, tell me all about the morning. I want to know everything,” she said.

I squeezed her perfectly peachy ass, encouraging her to rock in my lap.

“It’s kind of hard to concentrate with you moving like that,” I groaned.

Amara stroked my face with one slender finger.

“Be a good boy and concentrate, and then maybe ill reward you.”

“Reward me how?” I asked, squeezing her ass again.

“Use your imagination,” she said with a smile while shifting her hips, catching my cock between her butt cheeks.

“You’re not making this very easy,” I groaned.

Amara smiled and climbed off my lap. She pulled my arm over her shoulders and snuggled up against me.

“Talk,” she said, leaning her head against my chest.

I took a few breaths, trying to lock down on my arousal. I remembered how I shut down my hunger earlier. I used the same trick and damped down on my lusts. My cock stayed hard, but my mind became more focused. I spent the next half hour telling her about the day’s exploits and what I had learnt about the limitations of my power.

Well, it started with Elsa waking up...”

I told her everything from the bubbles, Laura, how I felt after and the extra commands I gave her. I carried on explaining how I shut off my hunger, Shannon, Pip and everything after.

“And then I got back, saw the changes to the twins, and here we are.”

“I don’t think you will ever be completely full of power, and what you’ve experienced so far, I would guess, is just the start.”

“Yeah, I know I’ve got four more wishes,” I said.

“I don’t mean more wishes. I mean the mind power you already have. It will continue to develop and change just like any skill gained by normal means.”

I thought this over. I had presumed that this was it, considering my power. I thought it was all dependent on the amount of sexual energy we put into it to start.

“If it’s going to get stronger with use, why put so much sexual energy into it to start? Not that I’m complaining, of course,” I smiled at that last bit.

“The sex provides the initial...” She looked for the right word, “creation of the power. It’s the use and your creativity that really decided just what you can do.”

“My creativity?”

“The more inventive you are with your power, the more you will be able to do.”

“Your wish had proved a good one. There may be no limit other than your imagination.”

I hadn’t thought of that. I realised I needed to try some out of the box thinking.

“The number of minds affected at once or distance are probably the only limiting factors”, she finished.

“Do you think I made the right call with Laura, and what about Pip?” I asked.

“Master, remember that it was commonplace for masters to amass huge harem’s and have many wives. It was a great honour.”

“I know, but we’re not in your time anymore,” I said.

I’m more going to lie. The idea of having a loyal harem of desirable women all eager to have sex with me was appealing. What man wouldn’t want that? But I still couldn’t help feel like I was taking advantage of my powers. To quote Uncle Ben, “with great power come great responsibility”.

“You need to give yourself more credit. Laura was unhappy, oppressed, in an abusive relationship, and was stuck in a dead-end job. You’ve changed all that. Given the chance of a better life. Some mind-blowing sex is a small price to pay for a second chance.”

She was right. It was the same reasoning I used myself.

“And Pip sounds just as horny as you.”

That was true. All I had commanded her to do was be okay with moving in.

“We come from different times. Have different views on social morals. I’m excited at the prospect of a harem. However, I think it will differ from what you are more familiar with. I don’t want hundreds of mindless sex slaves. Thralls to simple use and discard.” I said after some thought.

“As is my duty, I will help you build the perfect harem, Master,” Amara said.

“Now, about your reward.” She said in a decidedly more sensual voice.

Ten minutes later, Amara was face down, ass up on the mattress, her fists tightly clenched with a handful of the duvet. She was naked again except for her thigh-high stockings. I asked her to leave those on. I was behind her, hands on her hips in a sort of partial squat position. My hips moved as fast as my enhanced muscles let me pound my cock down into Amara’s asshole.

Pre-bonding, I would never have been able to hold this position for even a few minutes, even if just staying still. To keep it while fucking was another level of difficulty I would never have achieved. Now, however, it was easy. The most challenging part was holding back from cumming.

My cock pistoned smoothly into Amara’s immaculately tight ass thanks to her anal enchantments. The self-cleaning and self-lubricating innate ability she possessed was almost as handy as her other cleaning ability.

Amara was gasping, moaning and screaming in uncontrolled pleasure as my cock stretched out her ass. The tight heat of her velvet-like anal sheath that hugged my cock was amazing. Totally different from her perfectly designed pussy, yet it felt equally amazing.

“Yes, Master! Pound my slutty little ass with your cock. Make me your submissive anal whore.” Amara groaned.

My sister Lauren had said something similar when I fucked her ass on this very bed.

I was more dominant, although I didn’t really see myself in a genuine dom/sub relationship. I loved it when Amara called me Master, even though I thought of her as an equal. With the twins, I loved it when they called me “big bro” while having sex. It was the reminder of the taboo incestuous aspect of our relationship and their tender age. It added even more excitement to our time together. I didn’t view myself in a true dom/sub dynamic.

The friction of Amara’s tight ass, her depraved dirty talk, and the sexual energy we created pushed me to the edge. With a shout, I buried all 8 inches of my cock in my genie’s ass and flooded her bowels with cum. When the almost painful clenching of my balls stopped, and I regained most of my primary motor skills, I slowly drew back. Amara’s still quaking ass held on tightly, fighting my retreat. With a ‘pop’, my cock pulled free, leaving her ass gaping obscenely.

I half fell, half-lowered myself back while Amara slid forward to lie flat on her front. I closed my eyes and took a few minutes to compose myself further. The physical exertion of sex was a somewhat moot point by now. My body enhanced to such a point it would never be an issue.

However, the light-headedness and euphoric delirium that followed, such as intense orgasm, were still very much something I had to deal with. I was just reaching the tail end of such nirvana when I felt the familiar brush of twin tongues up my cock. Opening my eyes, I saw the big blue and green eyes of Elsa and Elsie, respectively, staring up at me.

Moving with perfect coordination, they licked my cock clean of cum. Elsa then moved down to kiss, lick, and suck my balls while Elsie took my cock straight down her throat. While Amara’s ass was self-cleaning, the twins didn’t know that. Still, they showed no hesitation in sucking my cock directly from cumming in her ass.

Their soft lips, agile tongues and wet throats kept me floating on the orgasmic high. Every few minutes, they would swap positions. It was around Elsa third time, sliding her mouth up and down my cock when I could hold off any longer. The twins obviously had learned my tell’s as they moved into position with no warning from me.

I gave them both two full mouthfuls of thick cum that they adored. After swallowing the first mouthful, they held the second in their mouth, only swallowing half. Rising to their knees, they kissed each other, passing my cum back and forth. Watching my 14-year-old twin sisters snowballing my cum was one of my favourite sites. I couldn’t resist reaching for my phone and adding a few more pictures to my quickly growing collection.

Elsa was holding her sister’s face in her hands, gently tilting her head back. Elsa raised herself, so she was looking down at Elsie, about 30cm apart. She carefully parted her lips, and a stream of my cum fell from her mouth into Elsie’s.

I took several pictures of that moment.

Just before her mouth emptied, Elsa ducked her head and pressed her lips against Elsie’s again, and they resumed kissing. My cock was still hard, and my balls were already full again. I was tempted to recreate what I had just done with Amara with the twins, albeit slightly less forcefully. Before I could put that plan into motion, my phone chirped its message tone. Swiping the screen, a message from my mom appeared.

Hope everything is okay. Be home in 30, will order takeout when back. Mom xxx.

Mom wasn’t as inept with technology as some parents, but still thought she needed to sign her texts or WhatsApp messages. I had told her it was pointless as I had her name saved on my phone. I knew who it was from. Still, with only 30 minutes left, introducing the twins to the joys of anal was off the table. Not only did I want to ease them into it, making it enjoyable for all of us, but I also wanted to have time to savour the experience. Besides, without Amara’s biological advantages, preparation time alone would eat up the little time we had.

I shot back a quick reply, then ushered the twins out with orders to shower and dress. Amara had recovered and cleaned us both and the room.

“So, before mom gets back, I need the ask. What’s with the twins? I know they’re around the right age for a growth spurt, but 4 inches overnight? Plus, you know I noticed their B’s are now C’s.”

“I thought you might have noticed,” she replied.

“Any other thoughts? The twins seem remarkably blasé about it, but I can’t imagine my mom will be so nonchalant.”

“I have a few ideas. I think the most plausible is that a combination of an increased amount of your cum, combined with the high level of sexual energy being generated, accelerated their growth. Maybe it’s by design to better serve you. Maybe it’s just a side effect.” She answered.

“So, no sudden flood of previously restricted genie knowledge?”

Amara wrapped her arms around my neck, and I took her waist.
