I thought we'd already given each other everything we had.
"Ah..."
"...Amazing."
Still deeply connected with Shizuno-san, I found myself hardening again.
"It's fine, we still have time until morning."
Shizuno-san tucked her hair behind her ear.
Then, we began what must have been our umpteenth round of sex today.
"Shizuno-san...!"
"Ahh, so big!"
Only the sound of our bodies slapping together echoed through the room.
"Hey, Shinta-kun, can I ask you something a little mean?"
"What is it?"
"Did you do anything naughty with someone at your part-time job at the family restaurant?"
I froze completely.
"A-are you psychic, Shizuno-san?"
"No, just a hunch."
"W-well, actually..."
I told her the whole story.
"I see."
"I'm sorry! Even though it's your special birthday, I..."
Shizuno-san gently embraced me.
"It's okay, Shinta-kun. Even so, I'm happy just being with you like this now."
She smiled sweetly at me.
"Shi...Shizuno-san!"
"Ahh!"
I began thrusting vigorously again.
"Shizuno-san...Shizuno!"
"Shinta-kun...Shinta!"
Thrust thrust thrust thrust!
"...No matter how many women you sleep with, I'll always open this pussy just for you...I'll never yield to anyone else."
"Thank you, Shizuno...but you're such an attractive woman, I worry someone else might force themselves on you someday..."
"Don't worry. Like I said before, I'm actually quite strong."
"Didn't you slap the manager at the supermarket where you worked part-time?"
"Yeah. Plus I have a black belt in Aikido."
"W-wait, really?"
Seeing me recoil, Shizuno's smile was adorable.
"Hey, Shin. Will you pour more of your cum into my pussy?"
"Shi...SHIZUNOOOOOOO!"
"Ahh! So sudden...ahhhhhhhhhhhh! I'm cummmmmmmmmmmmmmmmmming!"
I kept creampieing Shizuno raw right up until checkout time.
