“Of course, like any pet, it naturally requires management—like feeding it.”
The statement wasn’t wrong. While slimes were used for sexual play, they were also designed to efficiently clean up semen, whether inside or outside the body. Already, the tentacles clung to their owner’s chest, eagerly sucking up the spilled semen.
“Nn—! Ah, it—it tickles…!”
The wet, squirming thing slithered across his chest, absorbing the fluid with an odd, sucking sensation. If one only heard the conversation, they might think he’d just received a puppy. But in reality, he was naked, his body writhing as the tentacles coiled around him. One slipped between his legs, wrapping around his cock and pulsing as it sucked. Trembling, Hyeonjun writhed at the unfamiliar sensation—something he’d never experienced before.
Hyeontae watched with satisfaction as his new son struggled. “It seems to like you. Look how eagerly it’s licking you.”
“Ah—! Nngh, don’t—don’t lick there…”
Though the shapeless, tongueless mass stimulated him, Hyeonjun perceived it as licking—likely because the tentacles moved with a wet, flexible motion akin to a tongue, and Hyeontae had described it that way. Hypnotized to accept anything, he now saw this eyeless, noseless, mouthless creature as a pet without question.
“Shh, it’s fine. You’re supposed to play with it like this, feed it. It’s a gift from Daddy, so take good care of it. You wanted a pet, didn’t you?”
“Ugh—! I—I know…! But it’s weird, stop—”
The tentacle, still coiled around his cock, now probed between his buttocks. Hyeontae added, watching it tease the perineum, “If you keep your legs closed, your pet might get hurt. Pressing your knees together like that—spread them when you play.”
“Nn—! Ah—!”
The strange, ticklish pleasure made his thighs clench instinctively. At the scolding, Hyeonjun forced his legs apart, but tension kept them stiff. Hyeontae knew his adopted son had never caused trouble at school—a quiet, obedient boy, if not a genius. So he spoke sterner.
“Spread them now. If you can’t, grab your thighs and hold them open.”
The reprimand made Hyeonjun tremble, but he obeyed, gripping his own thighs to force them apart. The tentacle seized the opportunity, wriggling eagerly toward his entrance. His fully erect cock, tangled in translucent pink tentacles, and his hole—parted just enough to hint at invasion—were laid bare. Hyeontae lounged on the sofa, observing the scene with leisure.
The tentacle pressed against the entrance, then slowly, coldly slid inside. Hyeonjun flinched at the chill, but the slick mass pushed deeper, indifferent to resistance. It was strange—formless yet firm, an unnatural pet.
Technically, it wasn’t even alive—just a sex toy developed by Hyeontae’s company. But what did it matter? People kept rocks as pets these days. He merely sat back, watching the tentacle fuck Hyeonjun.
“Hah—! Nngh, don’t—don’t lick, it’s weird…”
Hyeonjun mistook the pistoning motion for licking. His face flushed redder, breath quickening—not just from the aphrodisiac coating the slime. Normally, the substance caused little more than odd tingles on skin. But once absorbed through mucous membranes, it burned. His body heated, itched, and his cock—trapped in writhing tentacles—stayed painfully hard.
“You’re playing with it well. Do that often.”
“Ugh—! Ah, I—I’ll play with it well…! Ah—! What… what should I name it?”
“Hmm… name it whatever you like. It’s your pet.”
The tentacle, previously focused below, now climbed upward, teasing his nipples. The budded peaks were mercilessly pinched and rolled, the tip flicking like a devious tongue. Hyeonjun gasped—he’d never been touched there before. Heat and itching spread across his chest.
“Nn—! Daddy, it—it’s getting hotter…”
Naked and tangled in wet tentacles, he still complained of heat. Hyeontae stood, stroking the sweat-damp hair from Hyeonjun’s forehead. “Doesn’t it feel good, even if it’s hot? Playing together?”
“Hah—! It’s—it’s strange…”
He couldn’t admit it felt good, twisting away as the tentacle thickened inside him. Now as wide as four fingers, it stretched his hole, the red inner walls visible through the translucent flesh. The slime pistoned lazily, coating his insides with fluid before growing bolder, demanding.
The tentacle’s purpose was simple: extract semen. It fed on it, so it stimulated every erogenous zone relentlessly, driving its host to climax.
Now fully enveloped, Hyeonjun’s body had grown hypersensitive—even the slightest touch made him jolt. The slime operated below human body temperature, but the aphrodisiac altered that. Once absorbed, the substance made the body crave heat. Exposure to temperatures above 30°C (86°F) would trigger extreme pleasure until the effect wore off. Hyeontae knew this. He merely smiled, petting Hyeonjun’s hair as the boy’s body betrayed him.
“Strange? You call this good.”
Hyeontae rubbed his own erection against Hyeonjun’s lips. “If only you’re enjoying yourself… that’s a problem. Come on—you know what to do. Make Daddy feel good too.”
Having already sucked him once, Hyeonjun hesitantly licked the tip as it pressed against his mouth. Below, the tentacle ravaged him; above, a stranger’s cock invaded. The slime wriggled deeper, hunting his prostate.
“Mmph—! Ah, nn—”
Every twitch of his hips made the tentacle burrow farther. Hyeonjun’s mind, fogged by hypnosis and aphrodisiacs, couldn’t process the overload. He only knew he had to please—so he lapped at the cock with flushed cheeks, his lower half consumed by the slime. His technique was clumsy, barely qualifying as a blowjob, but Hyeontae savored the amateurish licks, stroking his son’s hair.
The sight alone was intoxicating: a boy he’d just met, fair-skinned and innocent, now dazed with pleasure as he serviced him. Blood engorged the cock in his mouth, ruthlessly claiming the small cavity. Hyeonjun gagged but couldn’t pull away.
“Tastes good, doesn’t it? You’re still unskilled… so you’ll need to practice daily.”
The tentacle milked his cock and prodded his prostate, desperate for semen. Finally sated, its movements slowed. After a final, deep thrust, it pumped a flood of fluid inside him. The sensation of being filled made Hyeonjun jerk, spitting out the cock in his mouth.
“Hah—!”
Designed to mimic sex, the slime was ultimately just a lubricant mass. Withdrawn, it returned to its inert, jelly-like state. Hyeonjun lay spent, eyes glazed, face flushed, panting. Between his splayed legs, the tentacle’s fluid leaked from his stretched hole.
“Good. That’s how you play with your pet—until it fills you up like that. And since it’s a pet, you’ll obviously have to stay naked and spread your legs, won’t you?”
Hyeontae pressed his erection against Hyeonjun’s chest, speaking slowly. Hypnotized, the boy would absorb every word as command. He ground the saliva-slick tip against a hardened nipple, making Hyeonjun arch.
The slime’s aphrodisiac had left his body starved for heat. Even this brief contact sent jolts through him.
“You’ll need to feed it… until it’s so full of semen it drips out like that. Understood? So why are you trembling?”
This time, he trailed a finger down Hyeonjun’s chest. The slightest touch made him gasp.
“I—I don’t know…! My body’s burning… itchy…”
“Hmm… I’d like you to report every time you play with your pet and feed it. You said you’ve never had one before, didn’t you? I’m not doubting your responsibility… but for now, show me.”
“Ah—! Hah… yes.”
“Good. Then get on the bed, spread your legs, and show Daddy what your pet just put inside you.”
Hyeonjun, ever obedient, climbed onto the bed in a daze, legs parted. His hole gaped, red and swollen from the tentacle’s attention, fluid pooling at the entrance.
“D-Daddy… my inside… it itches…”
He whimpered, squirming. The aphrodisiac had peaked—his mucous membranes burned, desperate for relief. He kept his legs spread as ordered but couldn’t stop rubbing against the sheets, making the fluid inside slosh and drip down his thighs.
