Chapter 38 - It's Adultery! "No Insertion, No Cheating, Right?"
"As long as we don't insert, it's not adultery, right?" Even I couldn't believe the words coming out of my mouth. My rationality inside me punched me like, 'No, you mad bastard!' But in that instant, my desire countered with, 'What're you gonna do about it? This is another world! I'm doing whatever the fuck I want!'
Yeah. This is another world. What're you gonna do? As an isekai transplant, my ethics don't have to match Earth's, right? Plus, my body's a half-human, half-beast with superior muscles incomparable to any local and a ferocious horse cock. It's only natural women go crazy for it, isn't it? With that ridiculous self-justification, I turned to Lianna, whose face had already shifted to that of a bitch in heat.
Her tired husband, the massive dildo in the back room of the shop, Lianna's fatigued face like she hadn't slept a wink... My mind latched onto one possibility.
"Lianna. Could it be... you're not satisfied with sex with your husband lately? That dildo on the bed... I'm not one to talk with what I've got, but it looked pretty big. Were you using it alone all night in the shop to vent your frustrations?"
"Ah... aaah..." Lianna's face flushed crimson, like I'd exposed her dirty secret, her expression a mix of shock and embarrassment. Looked like I hit the nail on the head.
"Normally, I'd pretend not to notice... but I'm a man too, and with a beauty like you touching me, I can't hold this guy back. So, here's my proposal..."
As I said that, the shock faded from her face, replaced by growing anticipation.
"Since we're already here, how about we just enjoy ourselves without any insertion?"
At my suggestion, a strangely joyful expression bloomed on Lianna's face.
***********************************************************************************************************
We'd stopped measuring midway, and with my hand on her shoulder, we entered Lianna's break room together. True to its name, it held just a desk, bed, and small wardrobe. A cozy little space, perfect for resting.
And there on the bed... the dildo. Not as massive as my horse cock, but still impressive. The thickest part matched her slender wrist, length around 20-25 cm? Big, but plausible—something even Earth women might use.
"A-as you said, my husband's sex drive dropped sharply a few years ago... I'd been pent up with frustration, then I met you, Divine Beast, and saw that huge cock... it shocked me..."
Tucked into my embrace with my hand on her shoulder, Lianna turned her head away, blushing in shame as she spoke.
"A-after his drive faded, I went to an adult shop a few times... but I was scared, so I stuck to his size. But yours wouldn't leave my mind... I started going bigger bit by bit, and a few days ago, I got this one..."
"...What's your husband's size like?"
She bowed her head and pulled a small cock-shaped dildo from a box in the wardrobe. Barely over 10 cm, pretty thin—below average.
It's been about two months since we met. For her challenges to escalate this far... she must've been seriously frustrated.
"My offer to 'enjoy each other' isn't a big deal... I'll use this to satisfy you, and you satisfy my cock in return. That wouldn't count as adultery, right?"
Deep inside, my rationality—dragged off and locked in a dungeon—clung to the bars screaming, 'It is adultery!' Whatever. No stopping me now!
I grabbed the big dildo, flexing my throbbing horse cock for show. Lianna bowed her head, then quietly nodded.
Yeah... that's it...
I laid her on the bed and brought my horse cock close to her face. Seeing it right there, precum oozing from the urethra, her expression turned to that of a bitch fully in heat.
"...Haa... haa..."
I savored her look, then pulled down her panties visible through the sheer negligee. They were soaked; her pussy juices stretched in strings as they came off.
I examined her drenched pussy up close. Mature bush, not virgin-tight but definitely experienced. Yet the color—bright pink and pristine—stirred me up bad.
"...Soaking like this, you were really looking forward to it, huh? Way lewder than I imagined."
With a teasing smirk, I slid one thick half-beast finger into her pussy. Maybe because of my half-beast build or my size, but this finger—roughly her husband's cock girth—stirred her smoothly.
"Ah, aaht...! Th-that... D-Divine Beast...!"
"Call me Sema casually. I'm 29, so I'll call you sis from now on."
Korean age makes me a 30-year-old dude, but international age 29 feels more like a young guy on the cusp. With that in mind, I casually declared the informal switch.
"Lianna sis. This is no joke—slid in easy, but it's clamping down hard every time I move. How long since you fucked your husband?"
"Ah, aht...! Th-that's... ab-about a year now...! Ah...!"
She's not that old—over a year with just dildos? Kinda pitiful.
"Can't insert today, but I'll satisfy you proper... enjoy it to the fullest, all that pent-up stuff."
"Aht, aang♡ N-no, can't♡ Ah! Aa♡"
I sped up my finger, and she grabbed my arm by her face, trembling harder. Way different from doing it herself.
"Aang, aht. Aaat! N-no...♡ C-cumming...! Aaaaang♡"
Clutching my arm, shuddering, she clamped down hard on my finger, squirting pussy juice everywhere in a light climax.
As she calmed from the tremors, I peeled the condom off the dildo and gripped it.
"Sis. No need for the condom, right? Feels fine bare."
The condom had that familiar Earth rubber grip; the dildo was sleek as it looked.
"Y-yeah... i-it's fine, Sema..."
"You can drop formalities."
I grinned, rubbing my horse cock on her cheek, smearing precum, and said,
"Alright... now you enjoy me too, sis?"
She stared blankly at my cock, then reached out and stuck out her tongue.
A married woman licking a half-beast monster's horse cock—not her husband's. Fuck, this was too hot.
"Ngh... slurp... churp..."
Her tongue work felt awkwardly amateur. Rarely done it for her husband? Lizbet's last blowjob felt more skilled.
"Hmm. Kinda clumsy... not much practice on hubby, huh?"
"Ngh... w-well... maybe once or twice..."
Once or twice? Jackpot.
"D-does it bother you...? Hubby seemed uneasy about it..."
"Puhaha. Hell no, I love it. Just do what you want, sis—no holding back."
Uneasy about this? Grow a pair, Lianna's husband.
She looked pleased and swirled her tongue more fluidly now.
"Then for this guy..."
I rubbed the dildo on her soaked pussy, coating it in her juices. She kept licking my cock, eyes expectant.
"Here it goes...?"
"...Y-yeah..."
At her go-ahead, I pushed the dildo into her pussy. Resistance, but steady pressure worked it in.
"Ngh...! Ah...! Aaang...♡"
Fresh purchase, maybe—her pussy hadn't fully adapted; tight squeeze. Fully hilted despite the pushback, she trembled, gripping my cock.
"Nghii... ngh... haa...!"
I checked her state, then slowly pumped the dildo.
"Hii...! Ah...♡ Aaa...♡"
Her grip tightened on my cock as she shook to the rhythm.
Her mouth stopped, so mid-pump, I said,
"Hey, can't stop now—make my cock feel good too."
She trembled, tongue out, but the quickening dildo made it impossible. I moved my cock myself.
"No good. Gotta use your mouth proper."
"Eh...? Mmph...! Hngh...!"
I shoved my horse cock into her mouth; her tongue resisted at first. But this rigid beast ignored it, sliding to her throat.
As expected, her mouth stretched perfectly around the monstrous size.
"Hoo... much better. Just work your tongue—I'll handle the rest."
Each dildo thrust made her mouth twitch and quiver. Panicking at first, she soon licked exploratively inside.
"Hngmph... hnngh... ngh...♡"
Feeling that, I ramped up the dildo's speed suddenly, pistoning hard. Her eyes widened in shock, hips bucking.
"Hngmph!? Mmph! Nnghii♡ Hngii♡"
Rapid dildo ravaging swept her like waves of pleasure; eyes rolling back, body convulsing.
"Hnnngmph...♡ Ngh...! Hngii! Nnnngh!!!♡"
Her tongue spasmed wildly on my cock; tears welled as tremors grew violent. Thrusting deep into her cheek while twisting/stabbing with the dildo—her waist arched wildly, feet kicking restlessly.
Free hand crushed the sheets, elbow shaking; hips bounced suspended, out of control.
"Hngmph! Hnnnnghii♡ Nngh! Ng♡ Nnnnnghii♡"
The dildo's pressure pulsed nonstop. She was cumming endlessly. My thick arm's horse-muscle power sent her to heaven.
"Hngii♡ Ngh! Nnnngh! Nnnnngngngngh!!!♡♡"
After tormenting her like that, a familiar surge rose from my balls. I rammed deep into her throat and yelled,
"Lianna! I'm cumming too!"
Max power pistons, then unleashed horse semen straight into her mouth.
"Hnnnngmph♡ Gulp! Krgh! Gack! Krhhhngh!?"
Vast horse cum overflowed her mouth, bubbling out. It sprayed her nose too, face contorting; final hyper-pistons arched her back fully.
"Hnnnngh...! Nngh....! Krhngh...♡ Hooob...♡"
Shuddering, she collapsed, passed out—still sucking my cock, eyes rolled back, face smeared in tears and cum. To me, she looked oddly blissful.
