Senior's Forbidden Anal Masturbation at the Pool
The next day, Eunji heads to school for lecture prep but detours to the swimming pool for her pre-class swim practice.
"Good morning, Senior!"
"Hello."
"Hey."
She returns the juniors' greetings with her usual cool demeanor, and a few of them blush and giggle as they watch her. Even without being lesbians, her striking looks and aloof attitude make plenty of girls' hearts race—it's how she's naturally gained her popularity. She never asked for it, but it's happened anyway, drawing all this attention her way. And today, that attention feels especially burdensome.
It's... probably fine, right?
Because right now, Eunji's ass still has the anal plug Taesu gave her yesterday shoved deep inside.
She'd come to school with it in, since her anal training and stretching needed to continue not just at home, but everywhere.
"You came wearing your swimsuit under your clothes today?"
"Ah... y-yeah... overslept a bit."
Normally she'd change here, but today she'd arrived already suited up, so the junior asks in surprise. Eunji brushes it off with an excuse, but if she'd changed here, it would've been obvious right away.
Why'd it have to have a green cubic gem on the handle, anyway!
The flashy green cubic sparkles on the grip, making it even more eye-catching.
Taesu issues the one-sided command and ends the chat.
Masturbate three times in a situation like this!?
A quick glance shows over ten juniors and friends around. The absurd order to pleasure herself with the anal plug right here leaves her flustered, but...
My pussy's getting wet on its own♥...
Eunji blushes as she feels her pussy growing slick. It's a ridiculous command she could just ignore, but her mind starts racing instead.
If I do it in the pool... it, it should be okay♥
Disobeying isn't even an option anymore. She picks her spot, tenses up, and slips into the pool. Memories of getting thoroughly fucked by Taesu here yesterday make her pussy clench. Looking back now, what they'd done could've easily been caught.
"Everyone here? First-years, let's start practice. The rest of you, warm up."
""""Yes""""
With practice and timed records for the first-years, third-year Eunji has some free time. She joins the unused lane with other juniors and friends, easing into the water to loosen up and chat lightly. Then she drifts to the corner, slowly sliding a hand to her ass.
"Haaah♥..."
Squelch
"Hngh♥"
Underwater, no one would notice unless they swam right behind her. She grips the anal plug and starts sliding it in and out, the pleasure she'd discovered yesterday building gradually.
Squelch squelch squelch squelch
A hole meant for excretion, forbidden for sex—yet developing it, masturbating with it, brings waves of taboo thrill and arousal.
Everyone's practicing, and here I am masturbating♥
They haven't noticed, but the sheer depravity of anal play in this setting floods her with intense excitement. The thick plug in a hole it shouldn't be stretches her forcefully.
Definitely looser than yesterday♥ Ngh♥ Aaah♥
The first time with anal beads had hurt a little. But starting thin, she'd taken them all easily by the end.
Feeling it after just one day♥
Now even this thick plug brings more pleasure than pain—she's lost in the new sensations.
To take Taesu's dick, I need to stretch more♥... Ngh♥
His cock is thicker than this plug, so it's not enough yet. But just one day in—she'll develop it slowly.
"Ngh♥... Aaah♥... Hn♥"
"Eunji, come check my form."
"Ah...... Got it♥"
Her friend calls, making her jolt. Still, she swims over casually. Even with her friend right there, she doesn't stop—thrusting the plug relentlessly, the taboo intensifies.
Closer than when I got fucked in front of the juniors yesterday♥♥
Yesterday they were behind the door; now her friend's in plain sight.
"Your arm angle here..."
Her friend seriously asks for form correction. Eunji helps with one hand...
Squelch squelch squelch squelch
"Like... ngh♥... that♥"
...while the other keeps pounding her ass nonstop.
N-No♥ Even with my friend here, I can't cum........ Nngh♥♥
Spurt!
Eunji climaxes anally right in the pool. Pussy juice squirts out forcefully, but it goes unnoticed.
They could drink my pussy juices mixed in the water from this close♥♥
The thought makes her ass clench tighter involuntarily.
Acting like a pussy even though it's my ass♥♥
Just like her pussy clenches with depraved excitement, so does her ass now. She gets why they call it the "back pussy."
"A-Alright, let's get ready too♥"
"Yeah."
It's time for the second- and third-years, so Eunji climbs out. Before the afterglow fades, each step rubs the plug, drawing a lewd smile she can't hide.
Her turn comes; she breaks her personal record again. Thanks to the plug tightening her ass and thigh muscles, she intuitively masters their use—something she'll realize boosted her skills days later.
Practice ends, and as everyone heads to the showers, Eunji joins them.
Still need to cum two more times...
Two more to hit Taesu's three-orgasm quota. She could stay in the pool or wait alone in the locker room. But...
It's better with others around...... Ngh♥
She's hooked on the intense taboo of masturbating in risky company, unlike solo sessions.
Squelch "Hnngh♥" Shhhhaaa
In the showers with everyone, Eunji turns on the water, strips off her suit, and pleasures her ass.
Squelch squelch squelch squelch
"Nngh♥... Hnngh♥... Haa♥"
Water and chatter drown her moans and wet sounds, but the tension has her pussy drooling.
Someone might see♥ Ngh♥ Haaang♥
Girls sometimes peek over partitions for fun. She laughs it off usually, but getting caught now would be disaster—everyone seeing her ass plugged and masturbating.
They can't find out about this♥
She used to be content with quiet solo play, but now only Taesu's musky scent or thrilling risks satisfy her.
Squelch squelch squelch squelch
She knows discovery would ruin her image, but she shakes her hips anyway.
"Ooh♥"
Spurt!
Eunji cums quietly, head thrown back, body trembling. The intense orgasm nearly buckles her knees.
Squelch squelch squelch squelch
One more to go—she resumes thrusting.
"Nngh♥ Ooh♥ Nngh♥"
"Senior Eunji, you leaving?"
"I-I'll wash up more♥ Ngh♥"
"Sure~"
As others finish and leave one by one, Eunji's too lost in ass-fucking to even pretend to shower.
"Cumming♥ Cumming♥ Cumming♥ Cumming♥"
Spurt!
Alone now, she climaxes again, pussy juice spraying loud enough to echo in the showers.
"Ooh♥... Ngh♥... Haa♥"
Pop~
The brutal orgasm nearly pops the plug free; she twitches, savoring the aftershocks.
Alone in the locker room, Eunji snaps a photo.
To prove she'd obeyed, she sends a pic of her slightly gaping asshole.
She's fully his bitch now, submitting to inspections as her ass develops. Yet Eunji buzzes with anticipation and arousal—mid-lecture finger-fucks, spreading wide for him to watch her hole wink. After a week of training...
"Perfect♥"
She fits the thickest dildo Taesu gave her right in, grinning lewdly. Tomorrow, she can offer her new virginity to Taesu... to her Master, filling her with joy...
