Using a Mysterious Spellbook Ended Up Creating a Slave Harem - Chapter 18

 Preparing the Fourth Slave

Having smoothly taken first place in the term-end exams, the brief rainy season with its sparse rainfall came to an end. The crest on Iroha, whom I had held the most times out of anyone, was also showing signs of change—its pattern had become more intricate than at the start, while its color faded back to a faint hue. It seemed that the more semen I forced her uterus to drink, the more the crest would mature. Since I had absolutely no opportunities to hold Erika due to her work, Chihiro's crest would likely be the next one to evolve.

Spending my days in such a manner, the hot summer arrived, and around the time summer vacation was just around the corner, the long-awaited contact from Erika arrived. She had finally succeeded in luring Rina Takechi out. The scheduled date was July 17th, the final Sunday before summer vacation, and the location was the apartment where Erika lived, which Rina Takechi had visited before. Erika's reasoning was that if it were the sex room near the high school—a place Rina had never been to before—she would undoubtedly be on her guard.

Erika's apartment was a 3LDK (three bedrooms, living, dining, and kitchen area), but apparently, it would be difficult to use the mattress I had deployed when lowering her into slavery. Her room was supposedly so packed with her belongings that there was no space to lay it out. Instead, I decided to purchase new restraining gear so I could enjoy turning Rina into a crest slave right on top of the bed Erika used. The methodology would basically be the same as it was with Erika, which shouldn't pose any issues.

Abstaining from masturbation for three days starting from Thursday as usual, I welcomed the eagerly anticipated Sunday. Rina Takechi should have been told that the schedule for today was to dine outside with just Erika, arrive at the apartment at 2:00 PM, leave the room at 6:00 PM, and then disband after having dinner together just like they did at noon. In reality, while the first half would follow the schedule exactly, by the time 6:00 PM rolled around and she left the room, she would be a sex slave completely loyal to me. It had been about three and a half months since I first saw her in the Class 1-4 classroom before the entrance ceremony—honestly, it had taken a long time, but the moment to fulfill my long-cherished desire was finally here.

Arriving at Erika's apartment around 10:00 AM, I first set up a hidden camera to keep the living room in view. This was to pinpoint Rina's exact location when invoking the sleep magic, but compared to the room near the high school where this step wasn't necessary, it was a bit of a hassle. After that, I retreated into the room designated as a walk-in closet—which was cluttered with various miscellaneous items—where I planned to lie in wait, and checked the feed captured by the camera on my smartphone. Around this time, it was hour for Erika to head out for her meal with Rina Takechi.

"Well then, Master. I am off."

"Yeah, I'm counting on you, Erika." 

"Leave it to me. I shall present Rina to my Master." 

"...If this succeeds, I'll give you a reward during your next day off." 

"Y-Yes! ......Very well, I shall return at 2:00 PM." 

"Understood." 

"Then, please excuse me."

After she departed, I ate the lunch I had prepared beforehand and killed time on my smartphone. Time seemed to crawl by, but finally, as it neared 2:00 PM, a notification popped up on my phone. Checking it, it was from Erika, stating that she was near the apartment building with Rina Takechi in tow. As my tension finally spiked, I held my breath and hid deep inside the walk-in closet, positioned where I couldn't be seen by merely opening the door.

After a short while, I heard the sound of the front door being unlocked and opened. The voices of young women echoed, followed by the footsteps of someone walking down the hallway.

"Erika-san. I'm going to borrow your restroom, okay?" 

"Sure. Come over to the living room when you're done."

While listening to the sound of the restroom door closing, I brought up the hidden camera feed on my smartphone for the time being. Waiting for Rina Takechi to exit the restroom while monitoring Erika's movements, the sound of a door opening and closing finally signaled her appearance on the screen.

On the screen, Erika said something to Rina Takechi before stepping into the kitchen. Rina sat down on one of the cushions placed on the floor, leaning her upper body over the table as if exhausted. Deeming this a chance I couldn't afford to miss, I targeted Rina Takechi's location and chanted the sleep magic inside my mind to invoke it. As I waited right there, the camera captured footage of Erika shaking her shoulder while calling out to her.

As I continued to watch, Erika moved away and vanished from the camera's field of view. Then, footsteps echoed in the hallway, and the door to the walk-in closet received a knock.

"......Phew...... It's clear." 

"Excuse me. Master, it was a success." 

"Yeah, looks like it."

Having unconsciously held my breath out of sheer nervousness, I let out a massive sigh. For now, to confirm Rina Takechi's condition, I decided to move to the living room.

Heading to the living room with Erika following behind me, I found Rina sleeping in the exact posture shown on the video feed. Just like Erika had done, I lightly shook her shoulder and called out to her, checking just in case to make sure she wasn't awake.

"Takechi-san? ......Are you okay?" 

"Soft breathing... soft breathing..." 

"If you don't wake up, something terrible is going to happen to you, you know?" 

"Soft breathing... soft breathing..." 

"............She seems perfectly out." 

"Yes, Master." 

"Then, let's proceed as planned. Erika." 

"Understood. Unless I receive word from you, I shall return at 5:00 PM."

"Yeah. Thanks." 

"Then, please excuse me. Please, take your time and enjoy yourself."

I saw Erika off at the entrance as she left the apartment. Once she finished locking the door from the outside, I engaged the deadbolt as well to ensure no one could leave from the inside. Returning to the living room, I opened the bedroom door along the way and moved next to Rina Takechi, my mood entirely elated. In a whispering tone, I spoke right into the ear of the girl who was letting out quiet sleeping breaths.

"Well then, let's head over to the bed, shall we? Takechi-san."

Using magic to temporarily boost my muscular strength, I scooped up Rina Takechi's completely limp body into my arms. Inhaling the lovely fragrance drifting from her as I carried her, I gently laid her down onto the mattress. Next, holding my smartphone in hand, I sat at her feet and pointed the lens toward her. From here on out, I was going to record every single inch of this Sleeping Beauty-like Rina Takechi onto my phone.

"...She really is a transcendentally beautiful girl."

Muttering a monologue to myself, I initially recorded from her feet up to her face, capturing her gorgeous features on the screen before pulling back to take a full-body shot, after which I ceased recording.

Setting the smartphone aside, I hovered over her, observing her heavenly beauty at point-blank range. The sweet scent radiating from Rina Takechi's body blended with the lovely fragrance of Erika—who normally slept here—left behind on the bed, stimulating my lust like an aphrodisiac. Faced with a level of beauty that even the exceptionally beautiful Iroha couldn't hold a candle to, I couldn't help but stare in fascination. Placing my right hand against her smooth cheek, my thumb slowly traced her alluring lips. Overcome by their softness, I couldn't resist bringing my face closer. Breathing heavily, I dropped a kiss onto her glossy lips. Yet, merely making light contact with her lips caused my excitement to soar to an astronomical degree. Assailed by a premonition that I might prematurely explode, I hurriedly pulled my face away and decided to move on to the next action.

With trembling hands, I began to roll her flare-sleeve blouse upward from the bottom. She was wearing a camisole underneath as if to obstruct me, so unfortunately, her underwear was not yet visible. Midway through stripping it off, I buried my face into the crook of Rina Takechi's neck, inhaling a chestful of her sweet scent. Next, guiding both of her hands into a position over her head, I slid the blouse off her neck and arms.

Naturally, the lower body was next. With my penis swelling into a rock-hard erection, I shifted my body down to Rina Takechi's feet. Reaching both hands toward the waist of her knee-length gathered skirt, I unfastened the belt and the clasp before placing my hands onto the fabric. Lifting her soft body slightly, I slowly slid the skirt down. While my eyes were entirely stolen by her pure-looking panties, I stripped the skirt past her toes, taking off her socks along with it for good measure.

Finally, it was the camisole's turn. As I peeled this upward from the bottom as well, her pale, toned stomach came into view. Continuing to slide it higher, Rina Takechi's breasts—encased in a bra that matched her panties—revealed themselves, pinning my gaze strictly to them. With my vision and consciousness entirely focused on her chest, I unconsciously stripped the camisole the rest of the way off. When I abruptly snapped back to my senses, Rina Takechi's camisole was resting inside my hand, and in my field of vision, she lay beautifully asleep, clad only in her matching underwear.
