“Sorry for the wait. I needed to get her ready for later, but…” He hands it over. “I suppose it’s time.”

“Time? For what?” Sato taps Der’s shoulder just as he says that, before everyone looks up, the sky darkening during the day as the moon and sun align up and form a particular phenomenon.

“The time to head out to the Astral Altar just outside and perform the ritual for Eclipse’s evolution. The Eclipse has come to us, and the time runs short...”

The Absol leads the whole family outside, towards the mysterious altar with the statues of Dialga and Palkia, with me holding the tables. “Each one of you has to hold a table: Der, Zero, Eclipse, Ami, Sato and Cross. We must hold onto one during this ritual, and as the prophecy says, Eclipse is to transcend into a new form.”

We step around the circle and hold the tables forward. Luness starts to chant a holy spell, floating before us as the tables glow brightly, and then float above him before he lands down. “Eclipse, step in the circle of stone tables! The rest close in further!” He calls in as he runs out, and Eclipse runs in further, before she floats near the tables. We also float close, as she shines even brighter than before. Her body started morphing with pointy ears, a double-forked tail, rings, dark blue fur, a red gem, and a lighter body. She also sprouts tiny wings with rings on it, and slowly falls down, landing on her tiny feet. We head over to her.

“Mom… Daddy… sisters…” Eclipse says softly, looking a bit taller. “I feel… different.”

“You have evolved into a new form, hun.” Zero hugs her tight. “Umbr… Esp… How about Eclipseon?”

“That’s what they are. She has evolved into this form due to the eclipse. You also contributed by making her the happiest she could be, with her own family around her to have her smile every day.” Luness says with a smile. “That’s not to celebrate in the end of this day, though. As the Demon Lord rises, and he slowly builds up to take over the world, Eclipse and her siblings must grow stronger. They will train under your wings as they enjoy the rest of their childhood. Once they grow, they will be the greatest warriors, and…”

He seemed to pause for a log moment, sweating as he looks at a side and mumbling something, before looking at them. “That’s it.” He chuckles softly. The family eventually joins in, before he invites the dinner at the back of his temple, now rid of demons.

Eventually, the family returned home, and their friends waited in there, giving her a happy birthday party, and having a very noisy party at that. They celebrated for hours, and at the evening, Eclipse eventually collapsed into sleep from using so much energy, and fell asleep. She was taken to bed back at home when the dinner was over, and she would smile in her sleep, ready to enjoy her childhood.

Today I woke up at bed, and got up. I dress up with my sister as she wears her birthday hairpin, while I arrange my school stuffs, and head downstairs, and then we talk about the exams I have studied on, before Eclipse, Sato and I prepare for school, heading out. Eventually, every student compliments Eclipse and her new form, while I chuckle and keep close while we head out to the classroom. We have some classes while we are at it, learning about anatomy, before we head for the swimming class. At the dressers, we change into our swimsuits, and I then realize I have a heavier chest that sister… I adjust the suit to my body and it feels rather tight. Sis and I swim in and practice our swimming skills, and then, the bell rings, and I go up to the showers.

Suddenly, I felt…something stinging at my loins, and my mind fuzzing up… Mom told me that the girls at this age experiment something called a “heat cycle”, and that I shouldn’t look at males while it lasts. I gulp at myself and keep my eyes closed, trying to think about pure things. I dress back up quickly and find out that I am dripping from my panties, and my smell seems to be too noticeable. I blush and cover my face as I run ahead and avoid looking at males, but the more I think about them, the more my mind just dissolves…!

I hide in a bathroom cabinet, hoping no one would find me… Soon, I pull down my skirt and look at my dripping pussy, leaning a hand over there and rubbing myself. It felt strange… relieving… Ah… I rub up and down like I have seen mommy do once… My hands get slick wet with the touch of my hands on my pussy… I suddenly rub my little button and let out a moan, quickly covering it in surprise, blushing deep red as I just keep on pushing my fingers in and out. Hopefully no man will find me-

“Sister?”

I shriek in surprise as I look at Eclipse right in front of me! S-She’s looking at me masturbating…!

“May I know what’s going on…?”

“I-I am going through something embarrassing…” I whisper quietly. “I am in a heat cycle… and I am going insane…”

“… I could help.” Suddenly, my sister, glows brightly, and after a while she reveals… himself. He is now a boy! His star also shifted around.

“E-Eclipse? We are siblings…”

“Hey, we didn’t come here just because of your heat… I am doing this for you because I love you.”

She… He blushed lightly, and teleported us to the dressers at the pool room, which was empty, and dragged me to the showers. “Here we should be safe.” He says as he undresses us with Psychic, showing his well-built male body, and his… oh gosh, that’s a big… penis. I swear it’s as big as half of my arm… Just looking at it is driving me crazy! That’s it! I kneel quickly, surprising him, as I suck on his cock deeply, moaning softly as I close my eyes and bob my head on his meat. I can hear his moans through my ears, and it’s driving me crazier for him to take me… Even if he’s my brother!

Soon enough, I pull off, having tasted on his salty precum, and pulling away to lie down on the floor and spread my legs for him. We both could see our sexes throbbing, but my own cunt was twitching like mad, aching for getting something inside…! My brother lowers onto me, and kneels before me, rubbing his tip against my lower lips, and I give cute moans as he looks into my eyes. “Do you enjoy this?” He asks me quietly, rubbing further, before reaching up to my breasts to rub at my nipples, squeezing my breasts and moving them around. I moaned loudly, but kept it quiet as he teased my breasts, and then I felt something push against my vagina. Then, I felt a sharp pain inside me as he slid in hard into me, and I held in my scream as I rolled up tears from my eyes, panting softly.

He leans onto me closely and licks at my lips. “Calm down… It will fade away eventually… Now allow me…” He slides back and forth, giving me stimulation and a new feeling as he claimed me… I felt a lot of arousal and lust as he plows back and forth, holding my legs and rolling his hips against mine, as I was watching him and warning him to be careful. My cunt sucked down onto his massive cock, feeling my walls stretched as he tried to reach for my womb, using my hands to rub my own pussy and my nipple, looking at him with loving eyes. He made me feel good, and ever since I became his sister, he always made me feel good, and now… he makes me feel lovely…!

I roll my hips faster against his own, squirting as I orgasm for the first time, throwing my head back and moaning loudly, only causing Eclipse to thrust in deeper and hit my G-Spot several times! He’s making me crazy! I cling to him and relax my body, allowing him to plow harder into me! It feels so great! I don’t want to stop! Fuck me like the little bitch that I am, brother! Make me yours! I love you! Ah! H-He’s filling me with his semen! He’s ravaging me while still cumming, filling me to no end as the excess made a mess for my pussy and my crotch! I can’t stop, neither do I want to stop! Fuck me, fuck me, fuck me!

Phew! I… have come for about 7 times inside her… She’s all out of it from so much sex, though. I noticed that she had a circle surrounding her waist. That’s the Safeguard, and she must have released it unwillingly while I claimed her. I wake her up and smile at her, as I help her up and to clean her in her weakened state, promising her that she’d suck on my cock. We used to sneak into our parents’ bedroom and watch from a safe hiding as we learned from them. She was hesitant at first, but then, I took the time to analyze something about her heat cycle, and she seemed to enjoy it in the end. I take her and give her something to drink, and take her back to the classroom. We meet up with Sato and head back home once classes are over, getting ready for dinner as I decide to shower. Eventually, I feel something licking at my shaft, and I look down.

Ami was licking off my cock and giving it kisses. “You sure enjoyed that, huh? Didn’t you have enough?” I chuckle, which makes her giggle and elicit a nod, now deep-throating me, allowing me to hold her head close, and I close the curtains before anyone comes in to see.

“Have you seen Ami? I need to do some homework with her help.” Sato asks from the door.

“Eh, she must have gone outside to talk with Cross and Luness.” I needed Sato out for a while, and she walks out, allowing me to fiercely thrust my cock into Ami’s throat, causing her to gag and reflex her throat tightly against my thick phallus, making me give stiff moans as I rub her ears. She holds onto my hips and sucks deep and tightly. With a groan, I finally release my seed into her mouth, giving her a taste of salty cum. Soon, I pull her off and order her against the shower wall. Once she is in position, I lean over and line up against her vagina, before pushing in again.

We silenced our moans with a sound-proof barrier, and we started thrusting against each other fiercely, thrusting back and forth as she used a Safeguard as I bobbed my cock in and out of her pussy, shaking our hips sideways sometimes as I felt her massive tits. Hmm, this feels really good. She feels really good, especially in her heat cycle. I release my seed once into her pussy, filling her again, although she almost lost focus on the safeguard, but managed to keep her balance. She quickly lifts up one leg and sets herself sideways on one foot, allowing me to hold her leg and ram harder. I rub at her clit while I lick into her mouth and suddenly say sultry things to her. “Do you love being speared by cock, my slut?” That gave me a nod from her, but no vocal response. I hit harder against her G-Spot and move my hips back and forth rapidly, hearing us moan loudly and lose ourselves as we mated. This must be how Mom and Dad feel like in those nights where we sleep, but it feels so damn good!

Eventually, I release my seed into her once more, and we keep going for 30 minutes. Soon, we hear knocks on the door. Dad calls. “Eclipse, where is Ami?”

I didn’t even know what to tell to Dad! I-If he found us like this… He-

“Brother is bathing with me, don’t worry.” Ami tells Dad. “Nothing else.”

“Ah, Ami. You could have told Sato you were here. It seems you are still afraid of bathing alone.” He chuckles softly. “Don’t be a liar next time, though.” Dad closes the door.

We wait for a moment. “Ah… Is he gone?”

“Yes.”

“Thanks for backing me up, sister…”

“Anything for my lovely brother.”

I give a sweet smile at my sister and kiss her. Suddenly, I revert to a female, and we giggle, before we wash up, dry up and get dressed, before we head to bed, and I set us down onto my bed. I’ll sleep with her and protect her as much as I wish to protect my family someday. I love you, Ami.

“I love you too.”
