The long two-month summer vacation ended in the blink of an eye.
"I can't get motivated..."
Yurina skipped her afternoon lecture and wandered aimlessly through town.
"Couldn't even see Shinta today either..."
Clutching at the vivid memories of summer break, she walked down the street with a dull expression.
"Hey, isn't that Yurina?"
When she looked up at the sudden call, she saw a typical flashy guy—blonde with piercings.
"Long time no see, how've you been?"
"Yeah, alright."
The guy giving her a half-hearted response was her ex.
"Huh? Hey, your tits got even bigger than before, didn't they?"
"Hah?"
"Did your new boyfriend grope 'em nonstop or somethin'?"
Ugh, sexual harassment from an ex? Gross.
"Hey, Yurina. Wanna do it for old times' sake?"
"You seriously asking me that?"
"C'mon, we were always a great match in bed."
It was true—back then, she thought sex with him was the best.
But now...
His face flashed in her mind.
"...Fine."
"Seriously? Hell yeah!"
"At that hotel over there?"
"Nah, I'm broke. Let's go to your place? You're living alone in college, right?"
Yurina fell silent for a brief moment.
"I'll pay. Let's do it at the hotel."
"Seriously? Thanks for the treat~"
Half-ignoring his stupid grin, she headed toward the hotel.
"Hey, wait up~"
Her first kiss was in middle school.
She dated that guy.
But they broke up soon after, and she started dating the basketball team captain. He wanted to have sex, but she turned him down, thinking middle school was too early.
Her first time was in her first year of high school, during summer break.
It was with a senpai two years older.
Being older, he was good at it.
He taught her all kinds of sex techniques.
They broke up when he graduated, and she started dating someone else.
In total, she'd dated six guys—and slept with three of them.
"How's that, Yurina? My big dick reachin' deep inside ya?"
Not even close, tiny-dick loser.
"Ugh, I'm coming!"
He came after just five minutes.
"Phew~ Yurina's body got even hotter than before. Couldn't hold back."
Stop grinning like an idiot.
"Cigarette, cigarette..."
Her ex quickly pulled out and started smoking, still naked.
"Huh? Why're you dressed?"
"I'm leaving."
"Aw, c'mon, stay a little longer."
"Sorry, not happening."
As a parting gift, she left him two ¥10,000 bills from her part-time job.
Once outside, she took a deep breath of city air—probably polluted, but it still felt refreshing.
"...That was boring."
Everyone said sex with her ex was amazing, but she just felt numb.
She'd hoped, even just a little, that it might help her forget the guy who was tormenting her heart right now—but no luck.
Slowly, she pulled out her phone.
Staring at the LINE screen.
Her usually quick fingers felt sluggish.
But she poured her heart into the message she sent.
*****
She sat cross-legged in her apartment, waiting.
When the doorbell rang, she scrambled to her feet.
"...Shinta, welcome."
Just seeing him in front of her made her sunken heart race.
"U-uh, thanks for having me."
He stepped inside and sat stiffly in seiza, glancing around nervously.
"What, looking for my bra or something?"
"N-no, not that..."
Smirking at his flustered reaction, Yurina fetched the bra she'd left drying on the balcony.
"Hey, look, Shinta. I used to be a 93H, but now I'm a 98I!"
"R-really? That's amazing."
"Yeah. I'm almost catching up to Shizuno-san and Ayako-san."
"Still in your growth spurt?"
"Nope~ It's 'cause I did lots of naughty stuff with Shinta!"
Yurina climbed on top of him.
"W-wait, Yurina-chan? Are you feeling okay—"
"Seeing Shinta's face made me feel better already."
She stripped off her clothes.
When her bra came off, her newly grown I-cup breasts bounced freely.
"I might have the biggest boobs at my college now."
"Y-yeah, maybe."
Even though they'd had sex multiple times, his nervous, virgin-like reactions were adorable.
"Shinta, let's kiss..."
She pressed her lips to his before he could answer.
At first, he hesitated—but soon, something clicked.
"...Mmh, ahh, Shinta... kissing feels... so good..."
Her mouth was already melting.
Then, still kissing, Shinta slid his fingers between her thighs.
"Ah...!"
"Yurina-chan, you're already soaked."
"Shinta, you dummy~"
She'd never used such a sweet voice with any of her past boyfriends.
He really had her wrapped around his finger.
"I'll give you a paizuri with my grown-up boobs."
She wrapped her surprisingly large breasts around his cock.
"Wow, Shinta's dick... Even though my boobs got bigger, it still sticks out!"
"S-sorry..."
"Why're you apologizing?"
Smiling, she switched to fellatio.
"Ngh, ahh... Feels amazing..."
"I'm glad. Shinta's dick is already so hard~"
Yurina straddled him.
"Here I go, okay?"
Even though she was dripping wet, taking his massive size was still a struggle.
"Hah, ahh... so big... Shinta's dick is really huge~ It's reaching deep inside me~..."
Moaning, she rocked her hips.
Her bouncing breasts ached with each movement—but it felt good.
"Ahh, yes! Shinta, you're amazing!"
Holding his hand while they fucked made her feel incredibly happy.
"Hey, let's do missionary."
She clung tightly to him in that position.
"Nnnngh! No matter how we do it, you keep hitting deep! Shinta's dick is seriously the besttttt!"
"Yurina-chan's huge boobs are amazing too!"
"Hehe, suck on them~"
The wet sounds of him sucking sent indescribable pleasure shooting through her.
Maybe that was why...
"...I love you... I love you, Shinta."
Her feelings spilled out before she could stop them.
"Out of all the guys I've been with... no, out of everyone in the world, I love Shinta the most!"
She hugged him tightly.
"Please... even if I'm second... let me stay by your side forever..."
"Yurina-chan..."
His expression turned serious as he thrust harder.
"Nnnhaaaaah! Don't bully my insides with your huge dick!"
"But Yurina-chan, you look like you're feeling really good."
"Yeah, it feels amazing! Having sex with Shinta feels so good I could die! Ahh, haaaaah!"
Her limit was right there.
"Yurina-chan, you can cum if you want."
"But Shinta hasn't cum yet... I'll hold on a little longer... nngh!"
"Don't push yourself."
Shinta pressed close and sped up his thrusts.
"No, stop... I'm gonna... cum..."
It was frustrating—she had way more experience, yet this former virgin was about to make her lose it so easily. But...
"Yurina!"
In an instant, her uterus clenched violently.
"I'm... CUUUUUUUUUUUUUUUUUUMING!"
Twitch, twitch, throb!
Her body convulsed wildly, and for a brief moment, she blacked out.
Ugh, she was making such a lewd face in front of him.
"Sorry, Yurina-chan... You okay?"
"...Yeah, fine... just need a minute."
Touching her lower abdomen, she could still feel the aftershocks in her womb.
"Of course I'm on the pill, but... if I got pregnant with Shinta's baby, I'd be a single mom."
When she said that, he looked slightly troubled.
"That's no good. If it happens, I'll take responsibility."
"You don't have to force yourself."
Smiling, Yurina touched his cheek.
