Finally, it was time for insertion. I took a deep breath once as I pressed the enlarged glans, which was not suitable for the young and small vulva.
"Nora I'll turn you into an adult woman."
Slowly, I moved my hips forward and inserted the glans into the vagina, widening the entrance. Feeling the resistance to break the virgin membrane, I invaded the very narrow vagina.
"Oh... I feel like she's narrower than her sister."
Although there was no shortage of love juice as lubricant, due to the stimulant magic and my cunnilingus, it was hard to gouge out the narrow space. Normally, Nora would be in extreme pain, but she was fine thanks to the effects of sleep magic.
"T-This is dangerous....I-I'm not gonna last long..."
The cervix and the tip of my urethra finally kissed as I felt a light ache from the excellent tightness. Her young body could not contain all of my hard penis.
"When I was Isla... I don't really remember."
With the excitement of my first experience, I don't remember if I was able to insert it all the way to the base into Isla While I was thinking about this, Nora's vagina was painfully tightening up on my meat stick, which was a foreign object inside her.
"Ah... I'll treat you to semen in your uterus."
Moving my cock back and forth inside the extremely narrow meat hole felt so good that I forgot about the pain. With both palms on her knees and legs spread apart, I increased the sexual sensation by grinding in and out inside her vagina with the help of her love juice.
"It feels good. You don't fall short of your sister."
"...Nnn... Nnn..."
In line with my movements, the sleeping Nora let out a light groan. While listening to her voice,I gradually increased the speed of my hips.
"Hah... Hah..."
"...Nnn... Nnnn..."
"I-It's about time...."
The pleasure of selfishly engaging with a beautiful, sleeping junior high school girl approached its limit. Finally, without showing any concern for her young body, I used my hips wildly and climaxed.
"I'm cumming!!"
I thrust deep into her to the limit and began to ejaculate. I bit down on the pleasure of releasing my semen, while dyeing her pure and spotless womb with my color.
"T-The feeling of conquest is amazing..."
My cock didn't even deflate once I let it out, it just sat there inside her. After the first stage of the lewd crest magic, I started moving my hips again, not even taking a break.
"Haa... Haa..."
"...Ggh... Mhmm!"
"This narrowness is unbearable..."
Even with the power of stimulant magic, the movement of her vaginal was not yet fully developed. However, the intensity of the tightness caused by the narrowness of the space was enough to compensate for this.
The pleasure of shaking my hips in the vagina that was slimy with love juice and semen so as not to lose the narrowness felt the best. I only thought about my own pleasure, and I moved my body violently and gouged inside Nora.
"Hah! Hah! Hah!"
"Hmm... Ummh! Hmm..."
"...It's nice to be with a sleeping girl."
I grabbed and secured her slender hips and continuously slammed my glans into the innermost part of her. The cum inside me began to rage for an exit as I moved my rod back and forth at high speed while being enveloped and tightened by her mucus-filled vagina.
"Aah... It feels so good! I'm going to cum!"
After moving my hips quickly in small increments and enduring to the limit, I let my cock escape from inside Nora. The inside of her body was also small in proportion to her petite body, and a large amount of semen flowed out of her vulva from my first shot.
"Ooh! I'm cumming..."
With my right hand, I grabbed the penis, which was bloated and bounced up to the limit on the verge of ejaculation, and squeezed it a little before shooting it into her lower abdomen. The semen that stained Nora's skin with vigor was as copious as ever.
"Haa... This is the end of the second stage. Nora."
"...Now, I'll turn you into a slave like your sister."
After regulating my breathing to some extent, I started exercising the lewd crest magic. As before, I placed my right palm above her lower abdomen and chanted the spell in my head.
At the same time as it was activated, the squirted semen showed a familiar reaction. While feeling the heat on my right palm, I waited for her lewd crest to be engraved.
"...Nnn... Nnn..."
When the bubbly semen that seemed to have boiled disappeared as it was sucked in, a lewd crest appeared instead. It was the same case as with the four previous times, but this was a simple pattern compared to Isla's pattern now.
"...Even if they're asleep, you can engrave the lewd crest..."
After confirming the planting of the lewd crest, when I looked at the clock, it was getting close to the end of the sleep magic.
"This time, I'm going to start hard from the beginning, so be prepared."
When I declared that to Nora, who was exposing her sleeping face, I inserted my meat stick that was still hard enough into her. I then took both of her legs and put them on my shoulders and furiously started using my hips in a so-called mating press position.
We connected with the sound of our flesh colliding as I put my weight on her immature body. The unreserved movement made a loud panting sound, and the intervals between the noises became shorter and shorter.
"Finally, the time has come for Nora to be reborn."
"Uhm! Hmmm! Hhuh!"
"Do your best for me together, sisters."
The vagina, which had changed due to the effect of the lewd crest, was holding my penis all the way to the base. The inside was not only narrow like before, but it was hotly entwined with my cock and stuck to me without any gaps.
Even at this point, it felt so good that my waist seemed to melt, but if I cum inside and register that I am her master, her vagina will suit me even more.
"Now, it's complete! Nora!!"
Realizing that ejaculation was imminent, I put my lips on Nora's lips. I moved my hips in a crushing position and delivered the final shot deep inside her.
"Hmm! Ah! Ahhh..."
Nora's vagina was squeezing semen out of the penis, and her cervix was sucking on the glans as if it were kissing it deeply. The released cum was sucked into the uterus as if it were being gulped down.
After enjoying the afterglow of my ejaculation inside her for a while, I pulled my face away and retreated over her young petite body. When I pulled out my meat stick and checked the lewd crest on her lower abdomen, they glowed as bewitchingly as ever. indicating that the lewd crest magic had been a complete success.
"Phew... Now I understand that even if you're asleep, you can still become a slave."
I checked the time, thinking I would awaken Nora from her sleep magic, but when I checked the time, there were less than five minutes left before she would wake up on her own. I waited for her to open her eyes while resting my sluggish body after sex, thinking that there was no need to wake her up.
***
Exactly one hour after I casted sleep magic on her, Nora raised her eyelids while raising her voice lightly. She stretched a little, then slowly raised her upper body and met my eyes, sitting beside her.
"...M-Master?"
Come to think of it, she doesn't even recognize me. I started by introducing myself to Nora, who seemed curious to think that the man in front of her was someone she was serving, even though she didn't know his name.
"That's right. I'm Ethan Carter."
"... I'm Nora Bennett. Please call me whatever you like."
After saying this, she scurried around and turned her head to move her gaze. As I was wondering about this behavior, Nora spoke to me.
"Um... Master?"
"What's wrong?"
"This is sister's room, isn't it? Where is sister?"
"...I had Isla go out. By the way, she is also my slave."
"Sister too!?"
"Yeah. Isla is my first. She'll be home at 5pm today."
"I see... Should I call you brother?"
"...Why?"
"Because Onee-chan is number one."
"I meant that she's the first to become my slave!"
"S-So that's what Master meant... Nora still has a chance to be Master's favorite..."
"...Nora?"
"...Please take care of Nora from now on. Brother?"
"Just call me Master normally..."
"Yes! Master!"
Nora responded cheerfully with a beaming smile. She seems to have a very different personality from her older sister.
"It's just the two of us until five o'clock in the afternoon."
She got up and hugged me. As I hugged her body back, which fit perfectly in my arms, I pulled her face close and kissed her sweetly.
"Come on, I'll love you."
I pushed her thinly glistening flesh down on the bed and leaned over it. Nora's legs were wide open, waiting for insertion, and I lovingly held her thin fleshy thighs and sank my rod into her.
