Using a Mysterious Spellbook Ended Up Creating a Slave Harem - Chapter 25

 Yuzuha Soejima - Part 2

​Finally, the moment of insertion arrived. Pressing the enlarged glans, which didn't match her young, small vaginal opening, against it, I took one deep breath.

​"Yuzuha-chan. I'm going to turn you into an adult woman, okay?"

​Slowly moving my hips forward, I inserted the glans while widening the entrance. Feeling the resistance of breaking the hymen, I invaded the very narrow vaginal canal.

​"Oh... it feels narrower than her older sister's... I think."

​Thanks to the aphrodisiac magic and cunnilingus, there was no shortage of love juice acting as a lubricant, but gouging through this narrowness was hard work. Normally, Yuzuha would be suffering from intense pain, but she was fine due to the effects of the sleep magic.

​"Th-this is insane. ...I don't think I'll last long..."

​While feeling a slight pain from the outstanding tightness, the cervix and the urethral orifice finally kissed. In her young body, my fully grown penis couldn't fit all the way inside.

​"With Iroha... I don't remember."

​Due to the excitement of the first time, I didn't remember if I was able to insert it all the way to the base with Iroha. Even while thinking about that, Yuzuha's vagina tightened around my flesh rod so hard it almost hurt.

​"Ah... well, I'm going to treat your womb to some semen, okay?"

​Moving my dick back and forth inside the extremely narrow flesh hole felt so good that I forgot the pain. Placing both palms on her knees to spread her legs, I rubbed up inside her vagina with the help of the love juice to heighten the sexual pleasure.

​"It's good. It feels just as good as it did with your sister."

​"……Ngh, ……ngh."

​In response to my movements, the sleeping Yuzuha let out faint groans. Listening to those sounds, I gradually increased the speed of rocking my hips.

​"Hah... hah..."

​"……Ngh, ……ngh."

​"Almost... almost..."

​The pleasure of selfishly copulating with a sleeping beautiful middle school girl brought me close to my limit. In the end, showing no consideration for her young body, I used my hips roughly and reached the peak.

​"I'm cumming!"

​Thrusting all the way into the deepest part, I began to ejaculate. As I stained her pure, innocent womb with my color, I savored the pleasure of releasing my semen.

​"Th-the sense of conquest is incredible..."

​Without wilting even after discharging once, my dick remained inside her. Having finished the first stage of the crest magic, and with barely any rest, I started moving my hips again.

​"Haa... haa..."

​"……Ngh, ……mgh."

​"This narrowness is irresistible..."

​Even with the power of aphrodisiac magic, the movement of the vaginal walls was still immature. However, the sheer intensity of the tightness from the narrowness more than made up for it.

​Swinging my hips to overcome the narrowness inside the vagina, which was now slippery with love juice and semen, provided the ultimate pleasure. Thinking only of my own pleasure, I moved my body violently and gouged inside Yuzuha.

​"Hah, hah, hah."

​"Ngh, ugh, ngh."

​"……Doing it with someone who's asleep is fresh and nice."

​Grabbing and fixing her slender waist, I repeatedly slammed the glans into the deepest part. Wrapped and squeezed by the mucus-filled vagina, the magma inside me violently sought an exit as I frictioned my flesh rod back and forth at high speed.

​"Ahhh... y-yes, it's good! It-it's coming out!"

​After moving my hips quickly in short strokes and enduring to the limit, I pulled my dick out from inside Yuzuha. Perhaps because her inside was small in proportion to her petite body, a large amount of semen from the first round flowed out of her vaginal opening.

​"Ohhh! I'm-I'm letting it out!!"

​Grabbing my penis, which had enlarged and throbbed to the limit right before ejaculation, with my right hand and giving it a few strokes, I fired it onto her lower abdomen. The semen, which vigorously defiled Yuzuha's skin, was as abundant as usual.

​"Haa... with this, the second stage is also finished, Yuzuha-chan."

​"…………"

​"……Now, I'll make you match your sister."

​After catching my breath to some extent, I began to invoke the crest magic. Just like before, I hovered the palm of my right hand over her lower abdomen and chanted the spell in my mind.

​At the same moment it activated, the spilled semen showed a reaction that was becoming familiar. Feeling heat in the palm of my right hand, I waited for the crest to be engraved.

​"……Nghh, ……ngh."

​When the foamy, boiling-like semen disappeared as if it were being absorbed, a crest appeared instead. It was the same as the previous four times—a crest with a simple pattern compared to what Iroha has now.

​"……So it's possible to engrave a crest even while they're asleep..."

​After confirming the implantation of the crest, I checked the clock and saw that the time until the sleep magic wore off was approaching.

​"Next, I'm going at it violently right from the start, so be prepared."

​Declaring this to Yuzuha, who was exposing her sleeping face, I inserted my still sufficiently hard flesh rod. Next, lifting both her legs and placing them over my shoulders, I began using my hips furiously in what is known as the folding position.

​Applying my body weight to her immature body, we connected, making a sound of flesh colliding. The relentless movements made loud slapping sounds, and the intervals between them grew shorter.

​"Finally, the time has come for you to be reborn, Yuzuha."

​"Ugh, ngh, mgh."

​"Serve me together with your sister."

​The vagina, altered by the effect of the crest, clamped onto my penis all the way to the base. Inside, it wasn't just narrow like before; it wrapped hotly around my member and suctioned tightly without any gaps.

​Even at this point, it felt so good my hips were melting, but once I creampie her and register myself as her master, the inside of her vagina will become even more to my liking.

​"Now, it's complete with this! Yuzuha!!"

​Realizing that ejaculation was imminent, I overlapped my lips with Yuzuha's lips. In a crushing posture, I moved my hips up and down, delivering the final blow into her deepest depths.

​"Ngh—! Ah! Ahhh..."

​Yuzuha's vagina showed a movement as if milking the semen from the penis, and the cervix clung to the glans like a deep kiss. The released fluid was sucked into the womb as if being gulped down.

​After savoring the afterglow of ejaculation inside her for a while, I pulled my face away and got off her young, petite body. When I pulled out my flesh rod and checked the crest on her lower abdomen, it was glowing mysteriously just like before, showing that the crest magic was a complete success.

​"Phew... so now I know I can turn them into crest slaves even while they're asleep."

​As I thought about waking Yuzuha from the sleep magic, I checked the time and saw there were less than five minutes left until she would wake up naturally. Deciding there was no need to wake her up, I rested my sluggish body after sex while waiting for her to open her eyes.

​+++

​"…………, …………, ngh...?"

​Exactly one hour after using the sleep magic, Yuzuha let out a faint voice and raised her eyelids. After a light stretch, she slowly sat up and her eyes met mine as I sat beside her.

​"…………, M-Master, is it?"

​Come to think of it, she didn't even know my name or who I was. Seeing Yuzuha look puzzled about why she thought the man in front of her was someone to serve without knowing his name, I started with an introduction.

​"That's right. I am Atsushi Saida."

​"……Yuzu is Yuzuha Soejima. Please call me Yuzu."

​Saying that, she turned her head and moved her gaze around, looking here and there. Wondering about her behavior, Yuzuha spoke to me.

​"Um... Master?"

​"What's wrong?"

​"This is my sister's room, right? Where is my sister?"

​"……I had Iroha go out. By the way, she is also my slave."

​"My sister too?!"

​"Yeah. Iroha is the first. She'll probably be home by 5:00 PM today."

​"Sister is... should I call you big brother instead?"

​"…………Why?"

​"Because you said sister is the first."

​"That means she's the first person, the very first one to become a slave!"

​"O-Oh, that's what it means... So there's still a chance for Yuzu to become number one..."

​"……Yuzu?"

​"……I look forward to working with you from now on. Big brother Master?"

​"Just call me Master normally..."

​"Yes! Master!"

​Yuzuha replied energetically with a bright smile. She seems to have a quite different personality from her sister.

​"It's just the two of us until 5:00 PM."

​She got up and clung to me. While hugging her back as her body fit snugly in my arms, I brought my face close, and she kissed me as if spoiling herself.

​"Now, I'm going to pamper you."

​Pushing her body, which had a faintly glowing crest, down onto the bed, I leaned over her. Feeling affectionate toward Yuzuha, who was eagerly waiting for insertion with her legs wide open, I cradled her thinly-fleshed thighs and sank my cock into her pussy.
