Sadistic Excitement (1)
Was I out cold at some point, or had I just woken from a dream...? I had no idea how much time had passed. At some point, I felt Ha-jun oppa shaking me awake.
"Hye-won? Wake up."
"Nngh...!? Oppa...? Huh? What time is it?!"
"Ah... don't worry. I came home early today, so we're ordering in."
"Tsk... Yeah...? What about Ha-jin oppa?"
"I'm right here. You were sleeping so soundly, I didn't want to disturb you... But, uh, your drool..."
So embarrassing. I'd been dead to the world, hadn't even prepped dinner, and now the twin brothers were snickering as they woke me up, making me feel even more pathetic. But the cold vibe from Ha-jun oppa lately seemed gone, which eased my mind a little.
"Stop laughing... Tsk. Oppa, you came home early today?"
I awkwardly changed the subject.
"Yeah... about that. There's something I need to talk to you about."
His serious tone made my heart sink. Here it comes, I thought. Divorce papers, maybe? Or showing me his mistress? My mind spun through every trashy drama scenario imaginable.
"Um... would you come to the massage shop with me?"
Totally unexpected.
Was he planning to show me his side chick at his regular spot?
"The massage shop...? Why there...?"
"Well... I've been dealing with erectile dysfunction lately. Took some meds..."
Oppa flushed a little. Probably embarrassed.
"Even tried hypnosis therapy. Now I get hard fine, but... premature ejaculation's the problem."
"So...?"
"Ha-jin's shop does treatment for that too. The owner said it's better if the wife learns it for your sex life."
"Huh? Premature ejaculation treatment? What's that...?"
Ha-jin oppa raised a hand slightly.
"Oh! I'll explain. Our place does erogenous massages too—direct genital work for women with frigidity or guys like premature ejaculation. Couples get better results, so that's why we're asking you to come along."
"G-genitals?! Isn't that a sex joint?"
"Aish, you two say the exact same thing. It's totally legal therapy. Doors wide open in broad daylight—what's seedy about that?"
A bit weird that genital massages were legal, but realizing my fears of cheating were actually just Ha-jun oppa treating premature ejaculation was so absurd I burst out laughing.
"Hehe... I'm tearing up. So, when do we go? Gotta work hard for oppas treatment."
Relief that he wasn't dumping me mixed with a dirty thought: maybe dreaming about sex with Ha-jin oppa wasn't so bad.
The place we went to with the twins was busier than expected, full of people getting massages. The faint herbal scent was soothing, and the cool groans from everyone made me curious how good it must feel.
Ha-jin oppa led us deeper into the shop, to a room marked "Staff Only."
"Oh? A woman with you today? She's gorgeous~ The wife?"
A tall woman greeted us—must be the owner. Even in heels, she was oppa-height, but with clear curves and androgynous beauty that probably turned heads. Still, she had this weird sexy aura that made me jealous, wondering if she'd catch Ha-jun oppa's eye.
"Ah... yeah. Brought her like you suggested."
"Good call. If she watches and learns, it'll help your treatment a ton."
"Ah... I'll learn hard."
"Hubby, strip down. Wife, have a seat here? I'll get some tea."
"Huh? Oppa has to get naked?"
"Yeah...? Makes sense for premature treatment—gotta stimulate the penis directly. Didn't he tell you beforehand...?"
Even so, the idea of Ha-jun oppa naked in front of another woman pissed me off. But watching him shyly undress was kinda cute, tempering my anger. His body, better lit than in our dim bedroom, stirred something erotic. Though he'd slimmed down a bit—no workouts lately, muscles softer.
"Lie down here? We'll start treatment~"
While I ogled oppa, the owner had changed into something tight-fitting. Smaller than me in places, but it clung, amplifying her sexy vibe—annoying.
She poured gel on oppas cock and stroked slowly. Her technique was so lewd I stared blankly.
"Ngh..."
Oppas cock hardened quick. His moans and the twitching shaft stirred something unknown inside me.
"First, circle the glans with your fingers, rotate slowly."
"Kgh..."
She circled his glans; he moaned softly, cock twitching.
"Sir, hold it. This is just stage one. Endure to the last for it to work."
She switched grips, glancing at me.
"Wife, next: thumb upright under the glans, wrap both hands to stroke just the glans up and down."
She rubbed nonstop; oppa groaned more each time. Then she paused, staring at him contemptuously—he missed it amid the pleasure.
She smiled at me. "He's struggling—short break."
"How many more...?"
"Mm... seven left. Ejaculate midway, and it's over."
"Ejaculate...? During treatment?"
"Yep~ Can't continue if you blow too soon. Must endure all stages without cumming~"
Her leisurely tone felt dismissive of oppa—irritating.
"Have some tea."
Ha-jin oppa slid a cup over. Dark porcelain hid the color, but herbal scent wafted. Perfect to calm my buzz.
"Thanks... I'll enjoy it."
"Okay~ Next treatment? Stronger stimulation—hold on~"
She gripped again; oppa flinched. Annoying, but arousing. Confusing.
"Basic grip, but shake just the glans."
"Ughaa...!"
Each stroke made his legs quake—tormented yet pleasured, lewdly hot.
"Sir, endure. You always cum here. Show off for your wife~"
She smirked mockingly. I'd have raged earlier, but now oppa clenched fists, body shuddering in ecstasy or agony.

So exciting I unconsciously rubbed my pussy.
"W-wait... break... please..."
Tears in one eye, he grabbed her hand.
"No~ Next~"
She reversed grip, squeezing hard. He arched back from the intensity.
"Wife: reverse hand, palm-wrap the glans, rake it down hard."
Like electric shock, his hips bucked, legs trembled.
"Twirl the glans sometimes. Press his chest with one hand to stop squirming."
He grabbed her shoulders desperately, but she pinned him, arching him back. Our eyes met—he saw me touching myself, looked away. A small yelp from her.
"Oh my! He's erupting big time."
Not "cumming"—erupting. Semen splattered her clothes, his belly. Too hot; I couldn't hold back.
"Haa... haa..."
Post-orgasm haze, head turned, just lying there. Rage at him cumming for her, plus his pathetic display—seared into my brain, thrilling.
"Tissues—wipe up. Wife~ a word?"
She wiped semen from her face casually, handed me a USB.
"Better to practice at home than here—cheaper, more effective. Study this video?"
"Ah... thanks..."
After that, fuzzy. Ha-jin oppa stayed to talk business, sent us ahead. We walked home silently, heads down. Sat at the table wordless.
"Ahem... sorry for the ugly show. And thanks... Embarrassed about the premature thing, but you came to help."
"No, oppa. Couples solve it together. Shower first—you're tired."
"Yeah... gonna wash up."
As soon as he did, I jammed the USB into my phone, played the video. Her sultry voice:
"Showing you eight premature treatments~"
Her hands on a raging cock. Weird for a demo, but I fixated on the acts.
Beyond the four on oppa, four more.
"Crab-claw grip: squeeze tight, thumbs extra on glans, shake up-down hard."
The cock twitched, legs quivered.
"Next three are intense—won't make him cum easy, so torment freely? Prep towels just in case."
One hand on shaft, thumb-index pinched glans.
"Clamp so it can't escape, torment glans hard. Ignore pleas—can't resist anyway."
She smirked quietly, pre-cum oozing—no gel needed.
"Next~ palm-rub glans, wipe pre-cum like cleaning."
The man grunted "kgh," "ngh"—bound, pleasure-pain blurring. Didn't matter; just needed ways to torment oppas cock.
"Finally: claw-grab glans, ravage. Most guys beg to stop—keep going."
"Uuuugh!!!"
His scream echoed, but her hands relentless.
"That's all the techniques. Endure this, and you're cured."
Unlike oppa, no cum—legs limp. Video ended.
"Want more? Come see me personally."
Her giggle irrelevant. My mind: fresh-showered oppa. Anticipating his torment for "treatment," I slowly fingered my pussy to dial down the excitement till he emerged.
