The Experience Course
I clapped my hands lightly, watching Erika’s mood lift after my coaxing.
Clap!
I gave Veronica my order.
“Miss Domura. Please show her around.”
“Understood, Boss. Miss Hanazawa, this way please.”
“Ah, y-yes.”
Her earlier spark of joy vanished in an instant. Intimidated once more by Veronica’s guidance and the salon’s opulent atmosphere, Erika trailed meekly behind her.
“Tsk. I wonder how this will go.”
I had already confirmed that magi-infused semen could function like a hand or cock wrapped in demonic energy, but I had yet to test moving it once it was inside the body. The thought made me slightly nervous.
Still, it didn’t matter.
Even without magi I could manipulate women with my looks alone and fuck them however I wanted, so things would work out one way or another. Lika and Yua were already thoroughly steeped in magi, so I had no data on how it affected a normal person. This was the perfect opportunity.
It was also one of the reasons I was running the place as a temporary opening. Today wouldn’t be about total corruption. I would treat it as a session to gain real-world experience.
“Um… Miss Domura? Do I really have to wear this?”
“Yes. It’s required for the treatment. The design maximizes skin contact area during the session.”
“Ugh…”
I stepped into the massage room where Erika’s trembling voice drifted out.
“Eep… eek!”
There she was, wearing the disposable underwear I had prepared for massages.
Oh.
The set used far less fabric and thinner material than regular lingerie. Erika had drawn her shoulders in tight, both hands covering her crotch. She refused to meet my eyes, turning her face away.
Her breasts were a little disappointing, though. She must have felt them while changing. Under the fluorescent lights the material turned faintly translucent, so she probably felt the same shame as if she were nearly naked.
I had chosen a T-panty style for the bottoms as well, so her ass would be completely exposed once she lay face-down. I would have provided a gown, but it seemed Veronica had deliberately withheld one.
“All changed?”
“Yes…”
“Manager, the Welcome Drink and oils, please.”
“Right away, Boss.”
Veronica left to fetch the semen cocktail and oils, leaving only Erika and me in the massage room. She was visibly embarrassed about whatever Veronica had said while she changed, but I chose to ignore her reaction and suggested gently.
“Shall we start with a quick consultation? Why don’t you sit?”
“Ah! Y-yes…”
She sat on the massage bed with a soft creak. I settled beside her, facing her directly, and asked a few questions.
“Any areas that feel uncomfortable or stiff during daily life?”
“Um… my shoulders?”
“Any past injuries?”
“No, none.”
Even while slightly curling into herself, I could feel Erika’s gaze repeatedly stealing glances at me. I acted completely natural, meeting her eyes and continuing the questions like a proper pre-massage health check.
A few minutes passed.
Knock, knock!
She jolted.
Slide.
“Boss, I’ve brought what you requested.”
“Thanks. Hand me the oil first.”
Veronica passed me the bottle of oil warmed in lukewarm water, then offered the luxurious crystal glass to Erika.
“W-what is this?”
“It’s our salon’s special Welcome Drink. The recipe is designed to calm the body internally and help expel waste before treatment begins.”
“Wow…”
The cloudy liquid inside the elegant glass gave off the impression of a galaxy. Its flavor was impossible to guess. When she tilted it, black thread-like strands drifted inside like haze swimming through the Milky Way. Erika stared, utterly captivated.
“Erika, go ahead and drink it. It’ll help the treatment tremendously.”
“Okay… here goes!”
After a brief hesitation at the unfamiliar appearance, Erika lifted the glass and drank. Her first sip made her frown slightly, but her eyes soon widened.
“Mm?”
Gulp, gulp, gulp!
It must have been sticky; even with her throat working, she couldn’t finish quickly. She kept her head tilted back for a while.
“Hic…!!”
She even burped when she finished. Erika’s face flushed cutely at the sound. A thick, white fluid clung to the corner of her open mouth.
“How does it taste? Drinkable?”
“Um…”
“The ingredients made it tricky to improve the flavor.”
I had spent days adjusting the blend, but Veronica, Yua, and Lika were already corrupted by magi and simply found it delicious. I had never heard an honest review from an ordinary person.
Erika closed her eyes, rolling the taste around her mouth.
“Oppa.”
“Yeah?”
“At first it was a little fishy, but the more I drank, the nuttier it became. I just couldn’t stop.”
“Really?”
“It’s like yogurt’s refreshing tang mixed with the aged depth of natto. That kind of flavor.”
“I see.”
I reached out and gently stroked her hair.
“Thank you for the honest feedback.”
“Eep!”
Only then, distracted by the drink, did Erika realize I was right beside her and that I had touched her. Her cheeks burned even hotter. Veronica approached and took the empty glass.
I told her, “All right. Climb onto the bed and lie face down. We’ll begin the experience course.”
“O-okay.”
Thump.
Erika moved quickly at my words. I watched her lie prone on the soft massage bed.
“L-like this?”
Her physique was lacking compared to Ayame, Veronica, or Yua. More like Lika’s slender type. Erika lifted her head to look at me, her face flushed apple-red.
“Relax your elbows and just lie flat. Here, I’ll place a towel on the face cradle.”
“Ah! Yes.”
I folded a nearby towel and set it where her face would rest. Erika settled fully prone.
“Then I’ll begin.”
“Mmph!”
With her face buried, she could only make muffled sounds. I observed her body for a moment. Her skin was as clean and flawless as her older sister Ayame’s, with no unnecessary fat.
Splat!
Standing beside the bed, I poured the warmed oil across her shoulder blades, right over the disposable bra top.
Drip, drip!
“Eek!!”
Even though I had warmed it to avoid shock, the new sensation still startled her.
“It’s a massage oil that aids muscle relaxation. Not cold, is it?”
“Eep! N-no.”
Erika nodded in understanding. The oil seeped into the disposable underwear and began to cling wetly. The thin fabric molded to her skin, faintly revealing the flesh beneath.
For a first real session, this is turning me on more than I expected.
“I’ll pour a little more.”
She gave a small nod. I spread the oil broadly across her entire back. The intermittent flinches gradually eased, and she let out a languid sigh. I cleared my throat.
“I will now begin the experience course. Starting with the upper body.”
Following what I had studied in the videos, I placed both palms beside her erector spinae muscles and slid them smoothly upward.
Sliiiide.
“Haaah?!”
From the small of her back all the way to the nape of her neck, I applied steady pressure. Erika’s slender spine twitched visibly. Her whole body trembled as she breathed into the towel.
“Relax, Erika. This step transmits body heat through the palms to loosen tense muscles first.”
She turned her head to the side, barely managing to speak.
“Ugh… it feels a bit strong.”
“It’s all part of becoming prettier. Loosening knotted muscles and expelling toxins can be as demanding as building muscle through exercise.”
“R-really?”
Doubt colored her voice. The claim that massage alone could make someone beautiful apparently sounded far-fetched. I decided to add a light provocation.
“Well, some younger clients can’t endure it and end up quitting partway. But surely not you?”
Erika immediately rose to the bait.
“I-I can endure it!”
“Then I’ll continue.”
“Y-yes.”
I worked her entire back with my palms, gradually moving toward her shoulders. At the nape and trapezius I used my thumb, index finger, and the edge of my hand to knead and squeeze the muscles in the standard shoulder-massage technique, yet I pressed with the precise movements I had memorized from the videos.
“Ah! It hurts!!”
“These muscles have hardened from sitting too long. This is the process of softening them.”
Erika whined at the unexpected pain. I ignored it, finished working her shoulders, then poured more oil generously around her scapulae.
“Eep!”
I watched the oil flow down toward her armpits, then slipped my fingertips into the hollows.
“Eek!!”
“This area tends to accumulate a lot of toxins.”
“W-wait! Heeek!”
Her side breasts, pressed outward by the bed, received small circular strokes from my fingertips as I loosened the area thoroughly. Erika writhed, letting out sounds that mixed ticklishness and embarrassment.
Squelch! Squelch!
The soft, yielding sensation beneath my fingers and the lewd, oily sounds of flesh filled the massage room. Inside Erika’s body I felt something stir—the Welcome Drink she had consumed earlier. The magi mixed within it was wriggling to life.
I concentrated on moving it. After finishing the opposite armpit, the magi began migrating toward her chest.
“It works.”
“Hm?”
“Nothing. Continuing.”
“Haa…”
I pressed both armpits once more, then slid my hands along the latissimus dorsi toward her waist, applying steady pressure. I repeated the motion back and forth a few times. The upper back was finished.
Staring at Erika’s glistening skin, I picked up the oil again while carefully keeping my painfully erect cock from touching her.
“How do you feel? A little refreshed?”
She turned her head to the side again.
“It feels incredibly refreshing.”
“Then I’ll move on to the lower body.”
“Y-yes. Please do.”
Plop.
Embarrassed again, Erika buried her face back into the towel. I smiled faintly and poured oil from her pelvis all the way to her toes.
“Hup! Heeup!”
She flinched when the oil reached her ass crack. The disposable T-panty grew dark and soaked, clinging tightly and making the cleft between her cheeks even more pronounced.
After coating her feet, I took one in my hand and explained.
“The lower body receives the most fatigue in daily life, so I’ll start with the soles and Achilles tendons. Standing or walking for long periods tires them the most.”
Holding her foot steady, I pressed my thumb deeply into the central hollow of her sole.
Press!
“Hiiii! Ah, mmph!!”
Her toes curled tightly and her ankle trembled.
“Does it hurt?”
“Yeah…”
Since I had confirmed I could manipulate the magi in the Welcome Drink, it was time to lay some groundwork.
“This acupoint connects to the kidneys and bladder. The components from the Welcome Drink you consumed will begin spreading throughout your body through this stimulation. After the soles we’ll move to the calves, then the thighs. I’ll begin now.”
Packaged as professional advice, my words made Erika nod with her nose still pressed into the towel. I massaged each part of her soles and toes with care, then repeated on the other foot. I lightly grasped and released her ankles before using my palms to knead her calves as though working dough.
Each time, Erika turned her head and let out shaky breaths. I continued in silence. After the calves, I wrapped my palms around her hamstrings, pushing the flesh upward with my thumbs and index fingers in long, firm strokes.
Sluuuuurp! Slurp!
Repeated strokes created a hot friction between oil, skin, and hands. Erika’s sounds shifted from sharp cries to loose, pleasure-soaked moans. Finally my hands reached the underside of her buttocks.
I looked at the massage panties. Though styled like a T-panty, the fabric covering her pussy wasn’t a thin string, so it still sat wedged between her cheeks.
“I’ll finish the lower body now.”
Pretending to complete the lower-body massage, I swept my hands lightly over her pelvis while using my fingers to push the panties deeper between her ass cheeks.
Slide.
With the fabric now trapped between her buttocks and only the waistband remaining around her hips, she looked almost completely naked. My cock felt ready to burst.
I steadied my voice as much as possible.
“Then I’ll begin on the pelvis and core area.”
