The rhythmic clatter of the train set my heart racing.
"Shinta-kun, did you eat breakfast?"
"Ah, no. Actually, I was in a bit of a rush and didn't have time."
"Here, take this."
Shizuno-san pulled out two aluminum foil-wrapped items from her bag and handed them to me.
"I made some onigiri."
"Eh, really?"
"It's kind of old-fashioned, isn't it?"
Shizuno-san said with a slight smile.
Meanwhile, I was so moved I nearly teared up.
This was the earnest, modest charm of an older woman.
Damn, I might only be able to fall for mature women now.
No—only Shizuno-san.
"Not at all. Thank you."
I unwrapped the foil.
The seaweed was perfectly moist, rich in flavor.
As I took a bite, a bright yellow peeked out from inside.
"Tamagoyaki?"
"Correct."
Shizuno-san gave me a playful wink.
"How is it? Does it suit your taste?"
"Yes, very much."
The gentle, soft texture of the egg, just like Shizuno-san herself, made me savor every bite.
"But really, thank you for this. Thanks to you, I think I'll have a great Golden Week."
"Mhm. I put a lot of thought into it."
"Thought?"
"When I found out the grand prize for the shopping district raffle was a 'luxury hot spring trip,' I knew I absolutely wanted to go with you."
"Sh-Shizuno-san..."
How much more did she plan to make my heart skip this early in the morning?
"I love you, Shizuno-san."
"Me too."
And like that, the train carried us toward our destination.
*****
"'Luxury' was an understatement..."
It truly lived up to its name.
"Sh-Shizuno-san! The bathroom door is gold!"
"Yes, it is."
"Sh-Shizuno-san! The view is incredible!"
"Yes, it is."
"Sh-Shizuno-san! Our room has an open-air bath!"
"Yes, it does."
Shizuno-san chuckled softly.
"Shall we get in together?"
I gulped.
"Sorry, I must seem way too excited."
"It's fine."
Shizuno-san slipped off her outerwear.
The generous curve of her breasts came into view.
Then, she gently embraced me.
"See? Can you feel how fast my heart is beating?"
"Y-Your chest is so big, it's hard to tell."
"Hey." She pouted. "I've been like this since yesterday—no, since we won the raffle. It's all your fault, Shinta-kun."
"Th-Then I'll take responsibility."
"Mhm."
*****
I sat on the edge of the open-air bath.
"How does it feel?"
Shizuno-san asked while pressing her breasts around me.
"Yes, Shizuno-san's breasts are so warm. And the water feels amazing too."
"Really? I might even feel younger."
"You're already plenty young and beautiful."
I sank deeper into the bath, bringing myself eye level with her.
Then, I latched onto her ample nipple.
Mmmph— I tugged it upward before letting go with a pop!
"Ngh—!"
Shizuno-san let out a sultry moan.
"Shinta-kun, you're getting better at this."
"R-Really?"
"Did Yurina-chan teach you a few things?"
"P-Please don't bring up Sato-san right now."
"Sorry."
Shizuno-san giggled.
"Just look at me right now."
She wrapped her arms around my neck.
Her soft lips covered mine.
Our tongues tangled, making wet, chuu chuu sounds.
"...Shizuno-san, I'm already—"
"Mhm, go ahead."
Still submerged in the bath, we joined together.
"Ngh—ah! Shinta-kun's big one—the hot water's coming in too!"
"Sh-Shizuno-san!"
Though thrown off by the unfamiliar resistance, I thrust desperately.
"This is... incredible... Your heat and the hot spring's... I'm going crazy..."
"Me too... I'm gonna cum."
"It's okay, let it out."
"Ah, but we didn't use a condom..."
"It's fine. Just... fill me up inside!"
Her words pushed me over the edge.
I came deep inside her—splurt, splurt.
"Haah... haah..."
We clung to each other as we came down.
"My... sperm might have dirtied the nice hot spring..."
"Fufu."
Shizuno-san kissed my cheek.
"Our trip together has only just begun... Let's do it a lot more."
"Okay."
"But if we keep going raw like this, I might end up pregnant."
She gazed at me with lustful eyes.
"That's fine. If that happens, I'll drop out of college, work, and make sure you and our child are happy."
"No, you can't do that. Your parents would be sad."
Shizuno-san smiled gently.
"Oh?"
Just looking at her like this was enough to get me hard again.
"You're such a bad boy, Shinta-kun."
"You're the bad one here, Shizuno-san."
And so, round two began—without pulling out.
