Trapped in a Dungeon with the Boss Monster

His fingers slipped out from her inner walls and caressed her entire vagina. 

Evie moaned as his fingers rolled over her clit. 

Gillen continued speaking.

“Move on your own until I cum. Once I cum, we’ll stop for today.”

With that, Gillen withdrew his hand from her pussy. 

Licking the juices off his fingers, Gillen pulled at the corner of his mouth, smirking.

Evie hesitated, swallowing her saliva.

“Come on.”

Gillen urged, squeezing her butt. Evie tightly closed her eyes, then opened them.

She took a deep breath, exhaling before grasping his enormous member, which she could barely hold in one hand. After giving it a few strokes, Evie slowly lowered herself onto it.

Taking in the glans, Evie held onto Gillen’s shoulder. the sensation of her entrance spreading still felt unfamiliar.

Gillen’s eyes beheld Evie, who slightly tilted her head back, catching her breaths.

His gaze swept over her half-closed eyes, parted lips revealing a small, red tongue, slender neckline, and beneath her collarbone, the plump breasts with erect nipples.

“Mmm, it’s so… big…”

Evie whined as she slowly took in Gillen’s cock, inch by inch.

With about two inches to the root, Gillen held Evie’s waist, pulling her closer.

“Should I lend you a hand?”

“N-No…”

Hearing the low voice ringing in her ears, Evie blushed and shook her head.

Gillen lifted her body slightly, then abruptly pressed down.

“Ah! Hng…”

His rough pubic hair brushed against her butt.

Evie shuddered greatly as Gillen’s enormous penis penetrated all the way to the root.

Her vision blurred, her mouth agape. With a contented expression, Gillen sucked on her small tongue that peeked out.

“Heeit, hngh, huu…”

“It’s fully inside now. It’s time to move.”

Gillen’s hand lightly patted Evie’s butt. Overwhelmed by the bulk filling her belly, Evie dug her nails into Gillen’s back. His firm, blue skin didn’t even show a hint of bruising.

Her nails scratched Gillen’s back as she lifted herself.

The deeply embedded penis slightly slid out.

Evie lowered herself to take it in again.

“Hm, uh… Ah, ahng…”

Evie’s movements were slow and weak as she rocked her hips. Gillen grasped Evie’s chin, opened her mouth wide, and pushed his tongue inside.

His thick, long tongue teased her throat, entwining with her small tongue.

The sight of her clinging to him and squirming looked so cute, but he knew that with just this much stimulation, no matter how much time passed, he wouldn’t reach climax.

“Uh, uh…”

Saliva trickled down from the corner of her mouth.

Titling her head, she kissed him while moving her hips, doing her best to satisfy Gillen, but her movements were all clumsy. As the kissing prolonged, she struggled to sway her hips.

Gillen parted their lips and smiled down at Evie. 

He chuckled as Evie gasped for air, her tongue peeking out.

As Gillen gripped her pelvis, Evie lowered her head dazedly, her small hands holding onto Gillen’s.

Her body then lifted upward, and the penis slowly slipped out. When it was almost out, leaving only the glans inside, Gillen lowered Evie’s body, and at the same time, strongly thrust his hips up.

“……!”

Chin up, Evie shuddered.

The deeply penetrating penis quickly slipped out from her inner walls but soon pushed back in.

Evie quivered and drooled, unable to utter a sound.

Sucking on the nipple before him, Gillen bucked wildly.

“Ah, ah, ng… Deep, deep, hoo, ahh…!”

Evie writhed, trying to push Gillen away. With a strong suction, Gillen released his mouth and laid Evie on her back.

Using his upper body, Gillen pushed up Evie’s legs and held her hands with their fingers intertwined. He swiftly moved his hips. Evie’s legs, draped over Gillen’s shoulders, flailing helplessly.

“Hng… Ah, ah, haang…”

A misty liquid splashed out from Evie’s vagina.

his throat emitted growls like a beast, Gillen increased his speed, ignoring Evie’s gasping moans.

He pulled his waist as far back as possible and then plunged his cock to the root, his hips shuddered slightly. Gillen humped again while releasing his seed inside.

A sticky mixture of semen and love juice trickled down from her perineum.

“Ah, ah, aah! Hng, mmh…”

Gillen suddenly straightened up and let out a deep breath.

Grabbing one of Evie’s legs, Gillen raised his waist once again, his hand reaching for her vagina.

Without taking his eyes off Evie, who flinched at his touch, he pressed and kneaded her exposed clit.

“Ah, huff… Don’t touch, ah, hah…”

As he rapidly flicked and rolled the clitoris with his fingers, Evie twisted her body. Gillen flipped Evie’s body without withdrawing his penis. Laid flat, she was too weak to keep her knees up.

Gillen, breathing heavily, hugged her from behind and continued his thrusts.

Still writhing in the climax, Evie’s toes curling and her feet arching.

“Haah… Evie…”

Evie shivered as the low voice reached her ear.

Tightly embracing her, he moved his hips vigorously as if ravaging a prey. Evie could only moan, sobbing weakly.

She couldn’t move unless Gillen let her. Even in her clouded mind, fear gripped her.

“Haayuk… Ah, ah… Huff…”

The once gentle movements that had slowed down at Evie’s whimper soon intensified again.

As his penis filled her insides, fully stretching her entrance, her inner walls tightened.

Leaving red marks on Evie’s nape and shoulders, Gillen opened his mouth with a low growl.

“Evie, can you feel it? I’ve reached this far inside you.”

Gillen caressed Evie’s lower abdomen and applied pressure, pressing firmly.

Trembling from taking Gillen’s penis to the root, her tongue stuck out and her hands tightly clutched the bedsheet.

“Ah, ah…!

Don’t… press… Hng…”

Gillen, groping for Evie’s bulging belly, smirked and hugged her while raising his upper body.

He put his legs under the bed, letting Evie lean comfortably against his chest.

With one hand, he fondled her breasts, rolling her nipples with his fingers, while his other hand teased her clit. Startled, Evie inhaled sharply.

“Ah, ah…! Huh, ah, uhng…!”

With each torment on her nipple and her clit, Evie jerked uncontrollably as if she was shaking her waist on her own.

Only after a quick rubbing of her clit brought Evie to climax did Gillen release his hand. 

He then gripped Evie’s trembling thighs, lifted her petite body completely, and lowered her while thrusting his hips up.

“…!”

Evie immediately clenched her jaw, biting her lips and her flailing hands grabbed Gillen’s forearm. Just as his cock, which had been pushed to her limit, seemed to slip out, he changed direction and surged back in. He repeated that act several times.

Even as Evie convulsed, unable to utter a sound, Gillen didn’t stop his movements.

The massive member relentlessly pounded the depths of her inner walls.

“Hugnh…”

A satisfied sigh escaped Gillen’s lips as he spurted something warm inside Evie. Her body trembled and soon slumped.

Her breaths were so faint that one had to lean in to hear them.

Gillen pressed his lips against Evie’s cheek.

* * *

Evie, who had been sitting casually against the wall, lowered her gaze.

Her swollen belly was now clearly visible. Evie rested her hands on her abdomen, briefly caressing it before slumping to the side.

Despite the coldness of the floor, the room’s warmth provided a somewhat refreshing sensation.

Evie lay motionless on her side.

When Gillen told her that a monster was growing inside her belly, she thought of death. But with Gillen constantly by her side, she couldn’t even attempt suicide.

Gillen, who held her in his arms and whispered love, and the monster growing inside her belly, everything was creepy and terrifying.

But now…

“Evie, are you lying on the floor again? Come here. You should be in a warm place.”

“It’s cool”

Gillen silently entered the room, picked up Evie, who was staring blankly at the floor, and took his steps. Evie buried her face in his chest, as she always did.

She unknowingly caught a strong scent of blood from his body, like a fragrance, and her mouth watered.

The smell of the blood from the creatures Gillen referred to as ‘heterogeneous.’

Above her head, Gillen’s laughter resonated.

“Are you hungry?”

“…Hungry. I’m hungry.”

Had she become a monster because she was pregnant with a monster child? Such thoughts crossed her mind but they quickly drowned by the overwhelming hunger.

Ever since having the baby, Evie always felt hungry and had to devour all the meat Gillen brought from outside the laboratory several times a day to satisfy her hunger.

Gillen carried Evie, heading towards the lounge. She scanned the brightly lit hallway.

The broken fluorescent lights had all been replaced with new ones, shining brightly. Sharp objects and fragments of corpses that had once littered the floor were nowhere to be seen.

Even the walls, which had been stained with dripping blood, had returned to their original color.

On the dining table in the lounge, as always, a meal was prepared for Evie.

It wasn’t the cultivated meat she used to eat before having the child, but the flesh of the creatures Gillen captured from the outside.

Meat emitting a tantalizing red glow from its sliced cross-section was piled on the table. Evie impatiently urged Gillen.

“Quickly, quickly.”

“Yes, dear.”

Something wet touched her cheeks and forehead before pulling away. Even in that brief moment it took to reach the table, Evie was anxious.

She couldn’t take her eyes off the well-cooked mound of meat, eagerly swallowing her saliva. 

As soon as she sat on the chair, she grabbed the meat with both hands and voraciously tore into it. Gillen looked at Evie adoringly.

As the child inside her grew, so did her appetite.

At first, the mere smell of meat would make her stomach churn, but now she had reached the point where she could devour all the meat filling the dining table. Despite eating so much, Evie remained thin as if the baby stole away her nutrients.

Glancing at her slender wrists and ankles, Gillen called out to her.

“Evie.”

Evie quickly finished the meat in her hand and was about to reach for another, but then she turned her head.

Sitting next to her, Gillen brought his face close to hers and lightly tapped his lips with his finger.

Evie briefly pressed her lips against his and pulled away, refocusing on the meat. Gillen smiled and pulled her into his embrace.

Even while nestled in Gillen’s arms, Evie’s attention was solely on the meat on the dining table.

Gillen felt happy to see her sit or lie lethargic except for mealtimes.

At least now, Evie didn’t try to leave him.

She would sometimes caress her belly and occasionally approach him on her own, seeking his embrace.

Gillen poked his finger at her puffy cheek, and Evie shook her head, finding his touch annoying. It was a stark contrast to the early stages of her pregnancy when she would cry to the point of exhaustion, try to kick her belly, or bang her head against the wall.

Removing his hand from Evie’s cheek, Gillen placed both hands on her rounded belly.

“Will it be a girl or a boy?”

Would the child take after Evie or himself? He would be happy regardless.

A new life would be born, a blend of heterogeneous and human genes. How lovely.

After finishing the meal and sucking on her fingers, Evie leaned against Gillen, stretching her body comfortably. Gillen stroked her round belly, then helped her get up.

He wiped her greasy fingers clean and went to the door, waiting for Evie to come.

With one hand supporting her belly and the other gripping her waist, Evie cautiously took small steps forward.

Gillen’s lips curled into a smile as he watched Evie approach with her adorable gait, reaching out her hand and asking to be hugged. Without hesitation, he lifted her into his arms. 

It seemed like Evie couldn’t even wait for the short journey to the bedroom as she squirmed in his arms, preparing herself for sleep.

“Mmm.”

After laying on the bed, he pulled her closer, wrapping the blanket around them. Evie wriggled briefly and settled into a comfortable position.

At that moment, Gillen raised an eyebrow.

Humans had entered the laboratory. Gillen hugged Evie from behind as she lay on her side, his hands caressing her puffy belly.

Although he could deal with the humans, it was time to put Evie to sleep.

He had already released lumps of flesh in the basement. And soon, the screams of the humans reached Gillen’s ears.

It was a simple matter to block out the sound.

Gillen, holding the sleeping Evie in his arms, buried his face in the nape of her neck. He felt a slight movement from her belly.

Softly. Listening to Evie’s steady breathing, he stroked her belly for a long time.
