The wish was fulfilled, and I could finally begin my plan. So, I didn't stay long at Nobita's house and soon took my leave.
Since my first target was Shizuka's mother, Michiko, I needed to remove her husband, that obstacle, from the house to play my cards to the fullest and successfully lure his wife into the abyss.
For that, I called my bodyguard, gave him a few instructions, and at the same time, from him I received a packet that contained powerful colorless and odorless aphrodisiacs in liquids, sprays, and other forms.
With that, I hurried back home.
Having stayed at Shizuka's house for so many days, I had already memorized the family's routine, so I had a clear idea of when to act.
Therefore, I waited until the time when Shizuka left for her piano lessons, the same time Michiko usually took her bath.
Once the moment came, I smeared some dirt on my clothes, tiptoed back home, observed quietly for a while, and soon heard the sound of running water from the bathroom.
Everything was just as I'd expected, so I walked to the door and shouted.
"I'm back!"
After that, I first quickly and quietly hid the aphrodisiac packet in my room, then went down toward the shower room, where I stripped off my clothes and tossed them into the washing machine.
The sound of water continued from behind the bathroom door, but perhaps hearing my footsteps, which I no longer bothered to hide, the sound stopped, and Michiko's voice came from inside.
"Are you back, Takashi?"
Hearing her voice from the other side of the door, I smiled inwardly and replied.
"Yes, Auntie. I got my clothes dirty outside, so I came back to put them in for laundry."
"Is that so? Then just leave your clothes aside. Your body must be dirty too; do you want to come in and take a shower together?"
Her voice sounded casual, perhaps teasing, as if testing my reaction.
"Is that alright, Auntie?" I kept up my act of innocence as I spoke. "Since I didn't have a mother, I never took a bath with a woman, and my grandfather always said that men and women shouldn't bathe together."
Hearing that, Michiko smiled.
"You're really sensible."
Furthermore, it seemed that the mention of my motherless upbringing, combined with all the small acts I'd done these past days to stir her motherly feelings, playing the part of a lonely boy in need of affection, made her truly consider inviting me in.
"It's okay," she said gently. "You're covered in dirt. Come in and let Auntie wash you."
From the faint splashes, I could tell Michiko had turned off the shower and stepped into the bathtub. Considering her tone, I could even guess that she wanted me to come in so she could scrub my back from inside the bathtub before sending me out again.
But for me, none of that mattered.
Once I stepped inside, she wouldn't be the one in control. Still, it was convenient that she was calling me inside on her own, or else I would have to enter 'by accident' and create unnecessary drama.
"Okay… okay."
Since everything was proceeding according to plan, I didn't refuse. Smiling faintly, I opened the bathroom door and stepped inside butt naked.
"You first… ah!"
Michiko watched as the door opened and was about to tell me to shower first, but when she saw what was between my legs, she couldn't help but scream out loud.
Although my penis hadn't hardened yet, it was still quite thick and reached halfway down my thigh, dangling in the air like a third leg.
Even so, its majesty was clear as it hung proudly between my legs. After all, it was the cock I had wished for, using Doraemon's gadget, one that had cost me millions of yen.
The system only said that I couldn't use Doraemon's gadgets to directly influence others, but it never said I couldn't use them to influence myself, right?
So, using that loophole, which wasn't exactly a loophole, I simply made my wish to have my body become completely healthy, fully mature, and perfectly functional on the inside, without changing how I look on the outside except for having a naturally larger and well-shaped penis and testicles, with the same sexual energy, feeling, stamina, and control as the world's greatest porn star.
Consequently, I got what I wanted, and everything felt naturally and completely under my control, as if in perfect harmony with my mind and body.
Now seeing Michiko's stunned expression, I couldn't help but smile inwardly in satisfaction. Of course, on the outside, I maintained a puzzled look and asked,
"Auntie, what's wrong?"
"Ah? Ah, it's nothing. You go ahead and shower first, then come in and soak for a bit. Auntie will wipe your body later."
Realizing she had lost her composure, Michiko quickly blushed and pretended nothing had happened, letting me take the shower first.
"Okay."
I obediently stepped aside, turned on the shower, and began washing in front of her.
Michiko tried to act calm and composed, but her eyes couldn't help drifting toward my dick as she murmured.
"It's too big… bigger than my husband's when he's hard. Even now, it's almost twice that size. If it were to harden completely…" Suddenly, she caught herself mid-thought and snapped out of her daze.
"Wait, what am I thinking?! He's still a child."
Seeing Michiko's distracted look, I wanted to laugh, but I still took a quick shower while holding my laugh and walked towards the bathtub.
Watching the penis getting closer and closer to her as I approached, Michiko actually swallowed subconsciously until my body entered the bathtub.
Since no clothes were blocking my vision, I could finally see Michiko's plump breasts exposed in full view. The white and plump breasts and the light pink nipples made me want to go up and take a bite.
"Auntie, what's wrong?" I sat in the bathtub and looked at Michiko, whose face was flushed.
Because the tub was cramped, Michiko had forgotten to pull back her legs, so when I sat down, the tips of my dick brushed against her ankles, startling her, and she quickly retracted her feet.
"N–nothing, I. You really do look… different from ordinary people," Michiko said with a faint smile, finally regaining her composure.
No matter how much Michiko tried to hide it, it was useless. After all, I could see in her character panel that her desire had now reached 30, and she had obviously been aroused by me.
'Hehe, now this will be fun.'
