The Law Major Wants to Date - Part 10
"Hehe... You were the one who seduced me first, Oppa. I really didn't plan on doing this today."
"If you didn't plan on it, then don't do it!"
I struggled, but Jiheon pinned my wrists to the bed with her hands from above.
"Wearing my clothes and even my underwear while sneaking into my room is no different from walking into a tiger's den with rice cakes and shouting 'Please eat me up!' right?"
"I thought you wouldn't unlock the chastity cage otherwise..."
She brought her face so close that the tip of her nose brushed between my eyebrows.
"You didn't come here just to unlock the chastity cage. You even risked cross-dressing to get eaten by me, didn't you? Oppa just poked the sleeping tiger's pussy fur."
Saliva dripped from Jiheon's mouth and landed on the bridge of my nose with soft taps.
It trailed down my philtrum and slipped between my lips.
"No... I really just wanted you to unlock the chastity cage... I didn't want anything like this!"
"Hmm. Is that really true~?"
"It's true, I swear!"
"Then what's this rock-hard little cock, Oppa?"
I had hoped for an honest handjob once the cage came off, but not actual sex. Definitely not.
With anxious eyes, I glanced downward. Her slit had just the right amount of plumpness to give it volume.
Pale pink petals peeked out cautiously from the cleft, already tinged with a faint blush.
She tried to act nonchalant, but the tension was obvious—her inner thighs and lower belly were visibly clenched tight.
As if sensing my gaze, the soft flesh quivered as though trying to push outward, and cloudy fluids began to seep from the wrinkled entrance, coating the surrounding skin.
Then, as if sucking in the lewd scent, my cock slowly sank into my little sister's cleft.
"My cock... it's going in...! Pull it out while you still can!"
"Didn't I tell you when I first locked the chastity cage? This cock belongs to me now. I get to play with it however I want, so what does it matter to you, Oppa? Coveting your little sister's property... I'm disappointed in you, Jiheon."
With one smooth thrust, my fully erect cock slid deep into her thoroughly soaked secret hole.
The inside was hot and tight at the entrance, while her soft, plump ass bounced pleasantly against my groin with every movement.
"Aah...!"
Jiheon trembled and cried out as she took me in.
My cock wasn't very big, so it threatened to slip out slightly whenever she moved her hips.
She pushed her ass back to keep it from escaping, almost unconsciously.
Thrust, thrust, thrust!
Just as it was halfway out, it plunged back in to the hilt.
Even at full depth, it probably only reached halfway inside her from her perspective.
As intense tremors traveled from her pussy to my cock, Jiheon gradually increased the speed of her hip movements.
The friction of her folds produced wet, obscene sounds as her juices squelched loudly.
My cock and thighs below were drenched in the overflowing nectar from her.
Her warm, soft inner walls wrapped around me, squeezing as if trying to milk me dry.
"Aahh! Stop...!"
Jiheon kept rocking her hips with a mischievous grin.
"Oppa's little cock is so pathetic, I love it... It doesn't even reach half of my pussy... Is this really the end? Hehe, I'm probably the only girl who'd have sex with a worthless cock like this. So from now on, only have sex with me. Other girls would be disgusted, but I find even your pathetic little cock adorable."
Jiheon's body was demanding my final release.
With my heart still unsettled, I could only brace myself for what was coming.
"Ugh...! You can't cum inside, seriously...!"
"It's fine. I only finished my period four days ago, so it's a safe day. Hurry up and fill me with all your love, Oppa."
I pressed my hips tight and trembled with both legs, desperately holding back, but it was useless.
After a few thrusts, I was already on the verge of climax.
The feeling of becoming one clashed with the sense that this was wrong.
Her insides burned hot, gripping my cock tightly enough to rival any onahole.
"Aah...!"
Finally, my whole body shuddered violently as I cried out.
A strange fear welled up from experiencing my first orgasm through proper male-female sex.
As if the orgasm had transferred to Jiheon, she began convulsing too, moving even faster.
Her inner walls contracted rhythmically, sucking my cock deeper inside.
Overwhelmed by the soaring pleasure, I found myself kissing her lips and tangling our tongues without thinking.
Our sweet breaths mingled, and tasting her soft tongue pushed me over the edge.
Spurt! Splurt!
Hot semen poured out in thick waves.
Jiheon thrashed in ecstasy, only stopping once she'd squeezed out every last drop.
Completely drained, I collapsed onto her bed with limbs splayed.
Sweat and her saliva covered my face. Jiheon leaned in again, licking my nostrils, eyelids, and cheeks clean with her tongue before giving me a deep kiss on the lips.
She looked like a snake flicking its tongue.
Only then did my cock finally go soft.
The Viagra must have worn off by now.
"Haa, haa... Did it feel good for you too, Oppa? But I was a virgin, you know. Look, my hymen didn't even break. Since I'm going to have sex with only you for the rest of my life, I'll keep my hymen until I'm an old lady. More importantly, you were a virgin too, right? Sharing our first times with someone we love like this... I feel like I'm going to float away from happiness."
Could this really count as a first time?
It was my first time putting my cock inside a pussy, but my actual first experience had been getting raped by Eunbi in the women's restroom while handcuffed and feminized.
"You're insane..."
"Anyway, we really need to sleep now, so I'll wipe your cock and lock the chastity cage again."
She grabbed wet wipes from the desk, slipped between my legs, and lifted them onto her shoulders, fully exposing my crotch to her.
Before locking the cage, she rubbed her cheek against my cock like a cat savoring its final meal, feeling its warmth against her face.
Click, click.
Then, as if it were the most natural thing in the world, she pulled away and began locking the chastity cage on me.
"Ugh... Can't we stop with the chastity cage now...?"
"No. I told you before, didn't I? Even though it's attached to your crotch, the ownership of this pathetic cock belongs to me now. It stays mine until you die of old age. So don't ask me to do anything with my cock. The cage is just to keep other women or even you from touching it without permission. I'll decide when it comes off. Understand?"
"Uuuu..."
She seemed to genuinely believe my attached cock was truly hers.
To put it bluntly, while legal ownership remained mine, all management and disposal rights had been entrusted to my little sister.
In other words, my cock was legally mine, but all practical usage and control rights had transferred entirely to Jiheon.
Without the trustee's—my sister's—permission, I couldn't do anything with it.
Going to the bathroom, even masturbating, all required her approval.
What was even scarier was how naturally Jiheon accepted this situation.
As if managing her big brother's most sensitive part was simply her right as his little sister, she kept the key nestled safely in her cleavage.
That key wasn't just a piece of metal—it symbolized her complete dominance over me.
After locking the cage and lowering my legs, her expression froze the moment she saw my ass crack.
"Huh? Oppa, what's this?"
"W-what...?"
Jiheon roughly yanked out the pink heart-shaped anal plug still lodged in my anus.
"Hyaa!?"
The sudden removal made the inner walls of my ass get gently scraped.
I let out a startled, feminine moan and twitched.
I had completely forgotten I was still wearing the anal plug on Eunbi's orders.
Love gel gushed out from my now-gaping hole that refused to close.
I must have used too much lube when inserting it.
After a moment, my tightly clenched anus began twitching and relaxing in fear.
Silence hung in the air until I timidly lifted my head. Jiheon was staring down at me with cold eyes.
Then she suddenly burst into loud laughter.
"Ahahahahahaha!"
"J-Jiheon...?"
She looked up at the ceiling and muttered to herself with a terrifying laugh.
"Hmm... So you want to face me head-on? That fucking bitch. This is hilarious."
It was the first time I'd ever heard my little sister curse, and it shocked me.
"Jiheon, why are you...?"
"Don't worry. That wasn't directed at you, Oppa."
Then she grabbed my balls with her right hand and squeezed them like she was wringing out a rag.
"Kuh...! It hurts...!"
"Oppa... Did you think I wouldn't notice you cheating with some strange woman?"
Jiheon's voice turned icy.
"I knew everything but pretended not to. No matter who you meet, you're still mine anyway."
My heart sank.
She knew? About me meeting Eunbi? How? Did I slip up somehow? Or did someone tell her?
But deep down, I realized my little sister had known all along.
Her face twisted in displeasure for a moment before her lips pressed into a thin, hard line.
The usual playful expression vanished, replaced by a sharp gaze that pierced right through me.
Her eyes were filled with shock, jealousy, and overwhelming rage.
If looks could kill, I would have been dead on the spot.
"But..."
Jiheon slowly opened her mouth.
"I don't know who this snake-like bitch is—her name or face—but she seems pretty formidable."
She fiddled with the chastity cage key between her fingers and muttered.
"I got too careless. I never expected to get hit like this... Actually, the chastity cage was a message to her. 'Oppa's cock is mine, so don't even think about touching it.' But she replied with the anal plug saying 'Do whatever you want with the cock, but I've already claimed his ass, so don't touch it.' She stole the ass I'd been saving for twenty years to enjoy myself. If I'd known, I would've developed Oppa's prostate first... Fuck!"
What the hell? Were these two using my cock and ass as some kind of messenger?
Eunbi treated me like her toy, and Jiheon treated me like her property.
Neither of them cared about my opinion in the slightest.
I hadn't even noticed they were using me to send messages to each other.
They were playing a game of territory over me—who could claim which part of me more thoroughly.
Consumed by rage, Jiheon slammed her fist against the bed frame.
She looked like she'd lost all reason.
The metal frame rattled from the impact. Her fist turned red and swollen from hitting so hard, but she didn't seem to care.
"Fine."
Jiheon took a deep breath and spoke in a coldly calm voice.
"Oppa, go ahead and cheat as much as you want."
Her eyes held a determined glint, like flames were burning within them.
"No matter how many vixens or sluts cling to you, I'll prove that you'll eventually come back to me."
Jiheon clenched her fist tightly.
"To do that, I really need to get into Seohan University. I'll have to stick to you day and night to protect you from all those crazy bitches."
As her anger settled, it seemed to transform into fierce determination.
Her eyes gleamed with obsession—not just for studying for the entrance exam, but for completely claiming me.
"Just watch, Oppa."
I didn't know what exactly had motivated her, but my little sister's drive to study had clearly intensified.
As her big brother, I couldn't decide whether to be happy or worried.
Getting into Seohan University was good, but her motivation was completely twisted.
"I'm going to Seohan University to be with Oppa 24/7." Was that a normal reason to study?
Still, the end result was that she'd study harder... so it was a good thing... right?
