A Boy in the Chastity-Reversed World Doing "Mama-katsu" ~The Handsome Boy With Huge Cock Gets Devoured by Lustful Mamas~ - 8

Chapter 8: The Mama Obsessed with Pet Play

Rin (39 years old, former veterinarian, pet play fanatic)

Seven months into mama-katsu.

The app’s reviews had surpassed 7,000, and the tags were flooded with things like “#Yuu-kunPetTransformationWanted,” “#WantToBeOwnedByAHugeCock,” and “#DestroyedByBeastPlay.” The women could no longer feel satisfied with normal sex anymore—they all wanted to completely dominate me as their “pet.”

This time’s mama was exactly the peak example of that kind of woman.

‘Rin (39 years old, former veterinarian, pet play fanatic)’

Her messages were already in full heat from the very first one.

‘Yuu-kun ♡ I’ll give you 350,000 yen, so please come to my house today? I’ve always dreamed of owning a “beautiful boy pet”… putting on animal ears and a tail, walking you on a leash, feeding you, mating… I want to do everything for real. I want to turn Yuu-kun into my loyal dog and ravish you like a beast until you’re completely spent ♡ I’ll keep you and take care of you all night long ♡’

350,000 yen. And it was for one night and two days. The reviews were terrifying: “Rin-san’s pet play is the real thing,” “I was kept for a whole week with the collar still on,” “My body can’t go back to being human anymore.”

But my body was already reacting. Just imagining being connected by a collar made my cock throb and twitch hard.

When I arrived at the luxurious house in the suburbs she had specified, Rin-san was already in full owner mode.

A beautiful woman in black leather bondage, holding a whip. 169 cm tall, firm E-cup breasts, a toned body. But her eyes were the completely crazed eyes of a beast. Her hair was tied in a ponytail, and her lips shone bright red.

The moment she opened the front door, she immediately forced me to prostrate myself.

“Welcome, my new pet ♡ From today onward, you are my loyal dog. Your name will be… ‘Yuu.’ I’ll give you that name.”

Rin-san wrapped a leather collar around my neck.

Click.

The leash was attached.

“Come on, get on all fours.”

Trembling, I placed my hands on the floor.

Rin-san smiled with satisfaction and stroked my head.

“So cute, Yuu… your cock is already rock-hard. Good boy ♡”

The inside of the house was completely pet-modified. In the huge living room there was an enormous doghouse, food bowls, pee pads, and tons of toys. Mirrors covered the walls so every angle of my appearance was visible no matter what.

“First, time to get changed.”

Rin-san put a black animal-ear headband on me and inserted an anal plug with a tail attached.

The plug was huge, and the tail was a fluffy wolf tail.

“Nn ah… my ass… it’s going in…”

With plenty of lube, it slid in deep—zubu zubu.

“Cute tail ♡ Now you’re a perfect loyal dog.”

Next she put knee and hand pads on me, turning me fully into a dedicated four-legged creature.

Rin-san tugged the leash and started the walk.

“Come on, follow me. Be a good boy and walk properly, okay?”

Around and around the living room. My huge cock was already painfully stiff, hanging down toward the floor, with pre-cum dripping in long strings.

“Wow… such a magnificent dog cock… the perfect stud ♡”

In the middle of the walk, Rin-san suddenly pulled the leash to stop me.

“Sit ♡”

I raised my hips and assumed the sitting pose.

“Good boy, good boy ♡ As a reward, I’ll feed you.”

Rin-san poured a white liquid that looked like her breast milk (actually cow’s milk laced with aphrodisiac) into the food bowl.

“Lick it up. Like a real dog—drink it all with your tongue.”

Still on all fours, I buried my face in the bowl and lapped at it—pero pero.

Juru juru…

The aphrodisiac started working, and my whole body grew hot.

“Fufu, your tail is wagging. So cute ♡”

Next was “paw.”

When Rin-san held out her hand, I lifted my front paw (hand) and placed it on her palm.

“Good boy ♡ Next is “show your cock.””

At her command, I rolled onto my back and showed off my throbbing huge cock.

“Wow… such an impressive dog cock… I might not be able to hold back anymore…”

Excited, Rin-san led me to the doghouse.

“This is your bed. But tonight is mating time. Get in the ‘show your cock’ position.”

I lay on my back, and Rin-san immediately straddled me.

Still wearing the animal ears and tail, in a beast-like position.

Zubu zubu zubu zubu zubu!

“Nn aaaahhh! So big! The dog cock is reaching all the way inside!”

Rin-san’s pussy had insane tightness. Her cervix clamped down hard on my glans.

Pan pan pan pan pan pan pan!

While gripping my tail, Rin-san slammed her hips wildly.

“Amazing! Yuu’s dog cock is the best! Wag your tail more!”

I thrust my hips back up at her.

The tail shook furiously—buun buun—and the anal plug kept rubbing my prostate.

“Hyau! My ass! It feels so good!”

Rin-san yanked my collar and gave an order.

“Come on, bark! Bark like a real dog!”

“Wan! Wan! Ah, ah!”

I was completely in beast mode. Animal-like moans echoed throughout the room.

Rin-san came over and over. She squirted so much that the doghouse became soaking wet.

“Breed me! Give me every drop of your loyal dog’s thick cum right into my womb!”

Doku doku doku doku doku!

A massive ejaculation. Rin-san’s womb swelled full.

But it still wasn’t over.

“Next, walkies outside ♡”

She took me out into the night garden. Under the moonlight, still leashed by the collar, I crawled on all fours.

The garden was large, but still outside… the embarrassment was killing me.

“Come on, pee on the pad.”

At her command, I let urine stream from my huge cock…

“So cute ♡ It’s like you’re marking your territory.”

After that, we mated again on the lawn in the garden.

This time Rin-san got on all fours, and I mounted her from behind.

“Come on, ravish me like a real stud dog!”

Driven by animal instinct, I pounded my hips.

Pan pan pan pan pan pan pan!

“Nn aaaah! Yuu’s dog cock is so beastly hard!”

Second creampie.

After that, the all-night mating continued while I curled up in the doghouse.

In the morning, Rin-san mixed her own love juices into the food bowl for feeding.

“Come on, drink it. Your owner’s juices taste good, don’t they? Packed with aphrodisiac ♡”

Because of the aphrodisiac, my cock stayed erect all day long.

During the day we did training in the living room—“paw,” “more,” “wait.”

Every time I failed, she whipped my ass.

Pash! Pash!

“Bad boy ♡ But your tail is still wagging. You really are a masochistic dog.”

In the evening, Rin-san put on animal ears and a tail too, turning herself into a bitch, and we mated face-to-face.

“Today I’m the bitch ♡ I want stud Yuu to impregnate me ♡”

We mated face-to-face on all fours.

Pan pan pan pan pan!

“I’m getting pregnant! I’m getting pregnant with Yuu’s baby!”

Third shot, fourth shot…

At night, back in the doghouse, we mated again while she held me tight.

“Yuu… I love you so much… I want to keep you forever…”

Fifth shot, sixth shot…

When I was finally released at dawn, I had become completely petrified.

Even after the collar came off, I instinctively dropped to all fours.

Rin-san stroked my head with satisfaction.

“You were a wonderful loyal dog… Will you come again? Next time I’ll keep you in a real cage for a whole month ♡ I’ll pay you 1,000,000 yen.”

By then, I had already become completely Rin-mama’s pet.

In this world, the mamas really don’t treat me like a human anymore.

My mama-katsu will forever stay inside the beast’s cage—.
