Even the usually relaxing mealtime was tense today.
"Shinta-kun, does it not suit your taste?"
Shizuno-san, sitting across the table from me, asked with slight unease.
"Ah, no. It's very delicious."
I took a bite of curry and replied.
"I see. There's seconds, so eat as much as you like."
"Yes."
I nodded with a slightly awkward smile.

"Eh, the G-Spot?"
After today's lecture, Sato-san called out to me again.
"Yeah. Since Shinta-tan is well-endowed, I think you're probably going all out in porn. But you're likely not hitting the G-Spot, right?"
"Huh?"
"Do you know what the G-Spot is?"
"I've heard the name..."
"It's a relatively shallow spot inside a woman's vagina. If you stimulate it, Shizuno-san might show you a whole new way of cumming."
"But I'm not very confident..."
"Don't worry. Yurina-sensei will teach you gently."
"Eh?!"
*****
And so, with a certain resolve, I invited Shizuno-san to my room.
"Thank you for the meal."
Having eaten my fill of curry, I leaned against the bed as a backrest, watching Shizuno-san intently as she washed dishes in the kitchen.
Steeling myself, I stood up.
"Ah, Shinta-kun. The dishes will be done soon—"
I hugged Shizuno-san tightly from behind.
"Shinta-kun?"
"Shizuno-san, I'm sorry. I..."
My heart was pounding so loudly I was embarrassed she might hear it.
Shizuno-san smiled gently at me.
She turned off the faucet with a firm twist.
"Let's go to the bed."
Though I was the one who initiated, I found myself being led by Shizuno-san as we stood by the bed.
We kissed, I caressed her breasts, and soon Shizuno-san's most intimate parts were exposed.
I stared at them intently.
"Don't look so much... it's embarrassing."
Shizuno-san's cheeks flushed slightly as she spoke.
Gulping, I swallowed hard and inserted my fingers.
"Ngh!"
Shizuno-san twitched in response.
In my mind, I desperately recalled what I had been taught.
Around here, maybe?
I curled my fingers slightly.
"Ah!"
Shizuno-san let out a rough exhale.
Startled, I gently stroked that spot with the pad of my finger.
"Fuuh... ngh..."
Gradually increasing the stimulation—
"I-I'm cumming!"
Shizuno-san arched her back.
A small gush of fluid coated my fingertips, leaving them slick.
I stared at the glistening wetness.
"...Shinta-kun, that was amazing."
Shizuno-san panted as she spoke.
Seeing her like that, I couldn't hold back any longer.
I hurriedly pulled down my pants—I was already rock-hard.
"Shizuno-san!"
I thrust inside her.
"Nghaaah!"
Normally, I'd lose myself and pound away mindlessly.
But this time, I suppressed that urge and searched for the spot I'd touched earlier with the tip of my glans.
Here, maybe?
"Ngh!"
Shizuno-san clenched her teeth slightly.
Aiming for that spot, I rocked my hips back and forth, thrusting against it with my glans.
"Ahh, hah! W-Wait, Shinta-kun...!"
Too excited to heed her voice, I kept moving.
With shorter, quicker strokes than usual, I relentlessly targeted her G-Spot.
"Ngh... Ngaaaaaaaah!"
Shizuno-san's moans echoed through the room.
"W-What is this... I'm... cumming again... I'm—CUMMIIIIIIIIIIIIING!"
Twitch! Twitch!
Shizuno-san arched even more violently than before, convulsing.
Her vaginal walls clenched tightly around my penis.
"Hah... hah... Shinta-kun, what's gotten into you today? It's different from usual."
"I tried stimulating your G-Spot. I wanted to make you feel good."
"Shinta-kun..."
"Um... I haven't cum yet, so can I keep going?"
"Of course. But... just wait a moment."
Concerned for Shizuno-san, who was still trembling, I buried my face in her soft breasts.
