Secret Anal Playtime in the Maso Sister's Room
I headed to the room of the AV pervert girl who secretly masturbates her ass behind her family's back, and not long after, Hasun came in after washing up.
"Did your aunt notice you came?"
"It m-mixed with the cola, so she didn't know♥"
"Too bad."
"Haaah♥♥"
If she'd caught the cum, it could've blown up into a big deal, but for a true masochist like Hasun, she probably would've loved it. 'That auntie too, someday...' With midterms looming, I couldn't afford distractions—studying came first. Hasun's mom had such a tantalizing figure and looks that I couldn't help fantasizing about fucking her once. She didn't seem like a pure maso sow like Hasun, but I'd seen endless porn scenarios just like this; I could take her anytime.
"Alright, let's start studying."
"O-okay...."
I put the auntie out of my mind for now, pulled out the textbook, and flipped it open. Hasun looked flustered, almost disappointed. We'd come here to study, sure, but we'd gotten handsy several times on the way, and she must've been expecting more of that. Still, avoiding a failing grade mattered more right now, so study we would. Our subject was nursing, not taught at regular schools but one of the electives here at our vocational high school, which covered all sorts of fields.
"S-so in emergencies...."
Hasun summarized the textbook in simple terms, and I jotted notes while absorbing it. 'Why the hell did this guy (Seojin) pick this?' Medical knowledge wasn't a bad skill to have, but it wasn't my thing, so studying felt like torture. Still, Hasun had a real talent for teaching—she explained everything so clearly that it actually stuck.
"Whew... let's take a break."
"O-okay...."
An hour straight without a pause had my head throbbing, but a few days like this and I'd dodge that failing grade for sure.
"Studying's exhausting."
"Y-yeah..."
"You seem totally fine even after this, though."
"I-I study two hours a day..."
"Huh... got it."
I'd figured she spent every evening at home jacking off to porn, but she was more diligent than I thought.
"Time for some toy play during the break."
Squelch!
"Hnnngh♥♥"
I jammed a finger into the asshole of Hasun, who was sitting right next to me, and she immediately started moaning lewdly, lost in pleasure.
"This hole's practically pussy-level already... how long have you been prepping it?"
"Ah♥ Uhn♥ S-since Master raped me♥...ah♥ that's when♥ uhn♥"
Her ass, fully tuned to feel pleasure from the slightest touch, clenched greedily around my finger.
"Developing it on your own without Master's permission, wandering around no panties... looks like you need more training."
"Hiiik♥ S-sorry♥ Ooh♥♥"
She trembled, sensing my anger, peeking at my face—but with her ass in ecstasy, her mind was elsewhere.
"Let's see what we've got..."
I pulled out the box from under the bed and picked a dildo. Hasun's masturbation toy collection was impressively varied. 'She blows a third of her allowance on this stuff...' Fitting for her perverted tastes; buying kinky gear was practically a hobby.
"From now on, anal masturbate with this until I say stop."
"Ah♥ Y-yes♥"
I stuck the dildo to the floor, and Hasun, face flushed with arousal, squatted over it.
Squelch
"Ooh♥♥"
The dildo, way thicker than my finger, slid into her asshole, and she shivered with a slutty grin.
Squelch squelch squelch squelch
"Ooh♥ Ooh♥ Ooh♥ Ooh♥"
Just tiny movements, but it was enough—she was drooling pussy juice everywhere. 'Shame, but this is as far as we go.' Any more and the family might hear. 'Though... one of them already caught on.'
My Golden Sun Sense picked up someone watching, but it didn't seem like a problem, so I let it slide.
"What're you doing here?"
"N-nothing!"
"Your sister's got a friend over—come say hi."
"N-no, I'm fine...."
Knock knock
"I figured studying's tough, so I brought drinks and snacks."
"Thanks, auntie."
I'd stuffed myself on snacks and cake earlier, but she went out of her way—no way I'd be rude about it.
"Ughhh......"
And behind her, a girl blushing furiously. 'Hasun's college sister.' Her massive tits screamed "Hasun's sibling," and she glared at me, face red.
"I'm heading to my room!"
"That girl..."
She'd bolted before I could greet her, storming into the room next door.
"Keep shaking that ass."
"Ha-ut♥ Y-yes♥"
Hasun had frozen instinctively with the auntie and sister there, but she resumed, slowly.
Squelch... squelch... squelch...
"Oh♥...ooh♥"
Moving slow and subtle to avoid detection, but as a sow who cums harder in front of others, she was sinking deep into bliss.
"How's the studying going?"
"Great, thanks to Hasun teaching so well."
Thud squelch!
"Mmph!?♥♥"
Hasun ducked her head, hand over her mouth to stifle the moan. I pretended to brush her shoulder, shoving the dildo balls-deep—enough to make her quake.
"Oops, guess Mom was oblivious~"
The auntie smiled, thinking her daughter wanted alone time with me, and stood.
"Study hard, you two~"
She seemed reluctant but tactfully left.
"Didn't cum in front of your own mom this time?"
"Y-yes♥ Uhn♥ Ah♥"
Hasun trembled with a dopey grin.
"If she'd seen that face, she'd know her daughter's a horny pig instantly... shame."
"Ih♥ Ooh♥ Uhn♥ Y-yeah♥"
Her mind shattered by intense pleasure.
"Those huge udders you inherited so perfectly... bet your auntie's a pig like you deep down."
"M-Mom's♥ Ah♥ Ooh♥ Ooh♥"
Squelch squelch squelch squelch squelch
Calling her mom a pig revved her up; she bucked her hips wildly.
"M-Mom can't♥ Uhn♥ Haaang♥"
She said no, but the conflict in her eyes marked her a total sow.
"Whatever... cum already, pig."
"Buoooooh♥...oh♥"
Spiiiish!
At my command, she squirted pussy juice massively right there, climaxing hard.
"Eh♥...ooh♥...ih♥ Th-thank you♥"
With an ahegao face, she took 20 minutes to recover. We finished studying after.
"I'll come study tomorrow too."
"Anytime, dear."
I eyed the auntie's body appreciatively and headed home.
.........................
"First time Sis brought a friend home."
A woman heading home after college lectures. Boing boing boing Just walking, but her jiggling tits drew men's sneaky glances.
'Disgusting.'
Thanks to her mom's genes, she had enormous, peerless tits that unwillingly attracted stares—the root of her man-hating grudge.
Park Ha-jeong
Hasun Park's younger sister, currently a college student. Even on the way home, the men's gazes disgusted her, so she hurried inside.
"Hm? What's that smell?"
She approached the elevator and caught an unusual scent.
"Not bad, actually."
Figuring it was air freshener, she shrugged it off—the pleasant aroma didn't bother her—and rode up.
Clueless to its true nature...
Anyway, she got home.
"Welcome back~"
Mom greeted her warmly as usual, but extra chipper today.
"I'm home."
"Guess what? Your sister had a friend over today..."
Ha-jeong had already spotted the unfamiliar shoes at the entrance, but she nodded along as Mom gushed.
'Of course it's a guy.'
She was happy for her sister's new friend, but a guy? That irked her. Sis had huge tits like her, decent looks and body—perfect bait for creeps. Unlike bold Ha-jeong, her shy, timid sister couldn't say no to favors. It worried her.
"She's studying in her room, so don't make too much noise~"
"Got it!"
With Sis's room right next door, Ha-jeong endured the nagging and headed to hers.
- Ahhn♥ Aahn♥ Ah♥ Uhh♥
'Huh? What sound...'
But hearing noises from Sis's room, she pressed her ear to the door to eavesdrop.
- From now on, anal masturbate with this until I say stop.
- Ah♥ Y-yes♥
'A-anal masturbation?! Wh-what the hell!?'
Expecting studying, the moans and words from what she thought was a study session made Ha-jeong swallow hard, ear glued to the door.
