Chapter 11: After School "Extra Training" Of Uncle Chris And His Nephew’s Busty Childhood Sweetheart~!

Days passed, and the atmosphere between Peter and Gwen, who went to school together, had grown painfully awkward since that "fateful day"...

Meanwhile, as school club activities buzzed with excitement, Chris, the swim team’s dedicated coach, took full advantage of his position.

His attitude toward Gwen shifted, his intentions growing darker...

During club practice, he continued to extend his predatory hands toward Gwen, a team member, under the guise of coaching...

During her "personal training," the careful and gentle guidance he once offered was gone, replaced by lecherous, harassing touches —

"Eek...!? U-Uncle... Coach...?"

In today’s practice, under the pretense of "proper coaching," Chris began groping Gwen’s body in the pool, his hands slyly caressing her plump, juicy ass in spots hidden from the other team members~

(Chris: Damn!!! This fucking ass is just as big as her tits...!! Fuck, this body is too damn hot!!! They’re too good for Peter, He wouldn’t be able to handle it, so let the experienced Uncle take over! (lol))

When Chris grabbed her ass hard, Gwen’s body shuddered, her sweet, trembling gasps escaping each time his fingers kneaded her soft flesh.

"Mmm...?? No... C-Coach, you can’t...??"

"Shh, quiet now, or Peter will notice~!"

Glancing at his oblivious nephew swimming hard in the distance, Chris slipped his fingers between Gwen’s swimsuit and her ass cheeks, fondling her sensitive pussy while she struggled to stay silent, desperate not to be caught.

"Mmph...?? Ngh...??"

(Chris: Heh heh, once practice is over, Uncle Coach is gonna give you some real special attention~?? (wicked grin))

...

After practice, Chris ordered Gwen to stay behind for "extra training."

"Gwen, you need to catch up with the others! I’ll be giving you some intense one-on-one coaching from now on~!!"

Peter glanced over with concern, but when Chris flashed him a reassuring look, his trust in his uncle won out.

So he left his busty, swimsuit-clad childhood sweetheart in his uncle’s care and headed home alone, completely unaware that he was sending a lamb to the slaughter...

His busty childhood sweetheart Gwen was the poor little lamb...

Soon, the other team members cleared out, leaving the school empty.

"Everyone’s gone. Let’s start your special training, my little Gwen~!!"

In the deserted locker room, Chris yanked off his swim trunks, revealing his already rock-hard, beastly cock, and ordered Gwen to suck him off!

"U-Uncle... I really don’t want to do this..."

"Call me Uncle Coach during practice~?? Heh, you don’t have to, but those videos from that day... you haven’t forgotten, right?"

"...!?"

"Y-You said you’d keep them a secret..."

"As long as you obey me, Gwen, they’ll stay secret~ (winks)"

Chris’s meaning was crystal clear: Gwen, you don’t want poor Peter seeing that video of me popping your cherry and making you squirt from climax, do you~? Neither do I~ So be a good girl and become Uncle’s obedient little fuck toy! That way, everyone gets their happy ending~~~! (lol)

"..."

Left with no choice, Gwen reluctantly began learning how to give a blowjob, her clumsy tongue awkwardly licking Chris’s cock.

Chapter 12: Taught How To Do A Massive-breast Titfuck By Her childhood Sweetheart’s Filthy Uncle And Rewarded With A Hard Fucked~

"Fuck, this pressure feels so good! I could get addicted to this~?? If it were my stupid nephew’s little dick, he probably wouldn’t be able to enjoy this perfect huge-breast breast compression at all. Only a big dick like your uncle’s, protruding from your cleavage like a hot dog sandwiched in a bun, can enjoy it so comfortably, right~? (lol)"

...

Chapter 13: As Gwen Grew Familiar With Uncle Chris’s Massive Cock, Her Relationship With Peter Progressed Rapidly Under His Relationship Coaching!

Lately, with Chris acting as her "love coach" and giving her advice, Gwen had been making bold moves. She started taking the initiative to invite Peter to movies, work on lab experiments together, and even deliberately bent over in front of him to adjust her backpack, letting her heavy, voluptuous breasts — stuffed to overflowing inside her tight clothes — sway right before his eyes.

Chapter 14: Uncle Chris: "Gwen, Doctor said I’ve got a sex addiction ... Please help Uncle...!"

Once inside the office, Chris dropped the act, wrapping his arms around Gwen. "Gwen, Uncle can’t hold back anymore. I went to the doctor, and he said I’ve got a sex addiction — it’s acting up bad. Help Uncle out, give me a quick one right now~!!" He started kissing her.

...

Chapter 15: Little Gwen’s First Time Sex In The School Office~!

A large office desk had been shoved into complete disorder. Papers, a pen holder, and a laptop had all been swept onto the floor. On the desk surface, a glamorous girl in a messy school uniform was being pinned down hard.

The one pinning her down was a strong middle-aged man — around forty, broad-shouldered, with faint veins showing on his arms. He looked fully capable of being her father, yet right now those rough, powerful large hands were tightly locking onto the girl’s waist and thighs, fixing her entire body on the office desk while he stood between her legs.

...

Chapter 16: In Order To Avoid Smelling, Gwen Had No Choice But To Head Back To Class With Peter While Her Belly Was Filled With Uncle Chris’s Thick Cum~

Gwen lightly punched Chris’s solid chest with her small hands. It didn’t hurt at all. Instead it felt strangely like a daughter acting spoiled with her old father, or like a couple flirting: "Wuwu... I clearly told Uncle not to cum inside...?? why don’t you ever listen...?!!"

...

Chapter 17: Poor Gwen Ran Into Her Aggressive Uncle Chris In The School’s Girls’ Restroom~

Ever since that crazy session with Chris in the school office that day, Gwen had started playing a game of hide-and-seek with her Uncle Chris again, desperately trying to avoid him. What she never expected was that she would get cornered by Chris in the girls’ restroom while she was alone using the toilet...

...

Chapter 18: Bold Cunnilingus In The Girls’ Restroom~

"Give my panties back..."

"Gwen, do you know? A woman who doesn’t wear panties is the most beautiful woman~ If you asked Peter for his true feelings, he would definitely like the version of you that doesn’t wear panties more~!"

"If that dumb kid Peter could see your plump pussy under there with no panties on, he’d definitely get so turned on he’d get a nosebleed~!"

"Nonsense... Peter isn’t a pervert like you..."

...

Chapter 19: Milestone Of Sex Experience In The School Girls’ Restroom Unlocked~!

When Chris lowered Gwen’s thigh from his shoulder and stood up, Gwen, who no longer had a support point, weakly slid down the wall and collapsed onto the floor.

Zip —

Then Gwen’s empty eyes watched Chris unzip his pants and fumble around inside them.

...

Chapter 20: Stimulatingly Riding Uncle Chris’ Big Cock Until Orgasm And Squirting In The School’s Girls’ Restroom~

Chris kept going anyway. After only a few thrusts Gwen started begging for mercy and had no choice but to obediently twist her butt and start moving on her own~

Gwen lightly bit her lip, her face flushed blood-red, brows slightly furrowed. She slowly raised her perky butt, letting the cock pull out of her wet hole by nearly four inches.

(Gwen: Just treat it the same as when Uncle ordered me to practice masturbating with the rubber dildo at home before...)

Thinking that, she slowly pressed her waist down...

Then...
