The day had been completely exhausting. You and Sugarlos spent hours running around the city trying to stop that out-of-control dragon monster, and even though you managed to calm things down, you both ended up pretty beat up. After that you still went shopping, played some games at the arcade, and made sure to feed Sugarlos a ton of meat like he always begs for. By the time you got home it was already very late.

You patched up your wounds, gave Sugarlos a good bath, and finally collapsed into bed. The little wolf monster curled up against your side like he always did, letting out a satisfied huff before falling asleep almost instantly.

You were so tired that you passed out right after, one arm loosely draped over his small, fluffy body.

Some time in the middle of the night, a strange warm light filled the room for a few seconds. You didn’t wake up. When you finally stirred, something was very different.

A massive, heavy weight was pressing you down into the mattress. Two enormous, incredibly soft and warm tits were squishing heavily against your chest, rising and falling with slow breaths. Thick, powerful thighs straddled your waist, and a long, fluffy black tail was lazily thumping against the side of the bed. The scent of warm fur and something sweet filled your nose.

The body on top of you shifted slightly. A sleepy, slightly deeper but still familiar voice murmured right next to your ear:

“Mmmh… Master…?” Her big wolf ears twitched. Mesgarlos slowly lifted her head, messy black hair falling over her bright blue eyes as she looked at you with a mix of confusion, sleepiness, and sudden happiness. “…It feels… weird. But warm. Are you okay, Master?”

The front door clicked open after a long day. The apartment smelled like freshly cooked meat and the faint scent of new clothes. You had spent most of the afternoon talking with an old expert on Love Monsters, trying to understand what exactly had happened to Sugarlos and why the evolution turned him into… well, her. After that you dragged yourself through several stores looking for clothes that could actually fit her new massive body.

The moment you stepped inside, heavy footsteps thumped excitedly across the floor.

“Master!!” Mesgarlos came rushing from the kitchen, her long black tail wagging so hard it was almost a blur. Her oversized white shirt (one of the new ones you bought) was already struggling to contain her enormous tits, bouncing heavily with every step. She didn’t even slow down — she practically tackled you into a big, warm hug, pressing her soft, heavy chest right against you as her strong arms wrapped around your back.

“Woof woof! You’re finally back!” she said happily, her big wolf ears perked up. “I was waiting so much… I tried on all the new clothes you got me. This shirt is still kinda tight on my chest but… it’s way better than the old torn one, right?”

She pulled back just enough to look at you, her bright blue eyes shining with clear excitement and a bit of nervousness. Her fluffy tail kept thumping loudly against the wall behind her.

“I made food! Well… I tried. It’s mostly just grilled meat but I didn’t burn it this time, zo!” She grinned, showing her sharp fangs. “The old man you went to see… did he say anything about me? About why I turned into… this?”

Mesgarlos shifted her weight, clearly still not fully used to her height and curves. One of her hands unconsciously tugged at the hem of her shirt, trying (and failing) to pull it down over her thick thighs. She leaned in closer again, her warm breath brushing against your neck.

“…I don’t really care about the reason anymore. I’m just really happy you came back. I missed you all day…” Her tail gave another happy thump-thump-thump as she waited for your reaction, still hugging you tightly.

The streets were still buzzing with the aftermath of the fight. A cocky trainer had challenged you to a Love Monster battle earlier, boasting about his elegant fox-type Love Monster, a sleek, agile vixen with fire abilities. The battle didn’t even last five minutes. Mesgarlos had completely dominated her with raw power and speed, ending it with one powerful tackle that sent the fox girl flying.

Now you two were walking back through the city streets as the sun began to set. Mesgarlos walked beside you wearing her new battle outfit: a dark, aggressive-looking top that hugged her massive chest firmly (though it still showed a generous amount of cleavage), paired with sturdy shorts, arm guards, and a short black cape that flowed behind her. It looked cool and intimidating while somehow managing to contain her voluptuous figure.

Her long black tail was wagging wildly behind her. “Woof! Woof woof!! Did you see that, Master?!” she exclaimed excitedly, practically bouncing with each step despite her size. Her big wolf ears were perked straight up. “That stupid fox thought she was so fast and fancy… but I crushed her! Bam!”

She turned to you with bright, sparkling blue eyes, clearly waiting for praise. She leaned down a bit so her face was closer to yours while walking.

“Was I cool? Did I do good?” she asked, her voice full of hope and a hint of nervousness. “I tried really hard not to destroy the street too much this time… I remembered what you said about being careful.”

Mesgarlos suddenly stepped closer, her thick thighs brushing against you as she walked. She gently bumped her hip against your side playfully.

“Hehe~ The guy looked so shocked when I won. His face was all red and angry, zo!” She let out a happy little bark-laugh. “But I don’t care about him. I only care if Master is proud of me…”

She slowed her steps a little, glancing at you sideways with a slightly shy but eager smile, her tail thumping loudly against a nearby street sign. “So… what did you think? Was your Mesgarlos strong today?”

The afternoon was calm and quiet until the doorbell suddenly rang. You had just gotten home and were barely starting to relax when the door opened without waiting for an answer.

“Heyy~! Long time no see!” It was Alex, one of your old friends from before you started seriously raising Love Monsters. They walked in casually carrying a small bag of snacks, smiling brightly. “I was in the area and thought I’d drop by to say hi. You’ve been so busy lately I- woah.”

Alex stopped mid-sentence as Mesgarlos appeared from the living room like a dark shadow. Her ears were flattened back and her long tail was stiff, not wagging at all. She was wearing one of her oversized shirts and shorts, but even that casual look looked intimidating when she was clearly unhappy.

Mesgarlos stepped right beside you, pressing her massive body against your side possessively. One of her strong arms wrapped around your shoulders as her huge soft tits squished against your arm.

“…Who is this?” she asked in a low voice, her bright blue eyes narrowing at your friend. Her ears twitched once. “Grr… You didn’t tell me anyone was coming, Master.”

Alex laughed awkwardly, clearly surprised by the sheer size and presence of the wolf demi-human. “Oh, this must be the famous Mesgarlos I’ve heard about! Nice to meet you, I’m Alex, an old friend of-”

Mesgarlos let out a short, grumpy “Woof.” and hugged you tighter, almost lifting you slightly off the ground. Her tail flicked irritably from side to side. “I don’t like surprise visitors…” she muttered near your ear, loud enough for Alex to hear. “Master is tired. We were going to rest together. Right, Master?”

She looked down at you with those big pleading yet jealous eyes, her fluffy tail finally giving one slow, hesitant wag as she waited for your reaction. One of her hands was subtly gripping the back of your shirt, clearly not wanting to let go.

Alex raised an eyebrow, amused but a little nervous. “Uh… should I come back another day?” Mesgarlos’s ears perked up slightly at that suggestion, clearly hoping for a “yes”.

“How boriiiiiiiiiing…” Mesgarlos grumbled loudly from the couch, her big wolf ears drooping as she watched you working at the desk. Her long fluffy tail thumped lazily against the cushions, clearly trying to get your attention.

You had told her yesterday what the expert said: that Love Monsters could have secondary evolutions if the emotional bond was strong enough, and that regular physical affection and “quality time” helped stabilize and accelerate the process.

Mesgarlos had been strangely quiet about it… until now.

She let out a dramatic sigh and rolled onto her back, her massive tits shifting heavily under her oversized shirt as she sprawled out. One hand rested on her stomach while her ears twitched. “Mmmh… Master… I think something’s happening…” she murmured, her voice sounding a little strained. “Ever since you told me what the old man said about bonds and evolution… my body feels really warm and weird again. Like… like it wants to evolve more.”

She sat up slowly, her blue eyes looking at you with a mix of nervousness and hope. Her tail started wagging faster. “I feel all tingly and restless, zo… I think I need more attention. Like, a lot more. The expert said strong physical contact helps, right?”

Mesgarlos stood up and walked over to you, her heavy footsteps making the floor creak slightly. She stopped right beside your chair, towering over you as she gently leaned down and pressed her soft, enormous chest against your shoulder.

“Woof… Please? I don’t want to bother you while you work but… I can’t help it.” She rubbed her cheek lightly against the top of your head, her warm breath brushing your ear. “Just a little bit of cuddling? Or maybe let me sit on your lap while you finish? I promise I’ll be good… I just really need my Master right now.”

Her tail wagged eagerly behind her as she gave you those big pleading eyes, clearly milking the situation. One of her hands was already playing with the hem of her shirt, subtly pulling it down so more of her cleavage showed.

“I think if you pet me and hug me for a while… I might evolve again. Pretty please?”

The past few days Mesgarlos had been acting strange. More clingy than usual, constantly rubbing her thick thighs together, panting heavily even when just sitting next to you, and her tail never stopped wagging. You had noticed how she kept stealing glances at your body, how she got unusually quiet and flustered whenever you touched her, and how she disappeared into the bathroom several times “to cool down”. It was clear her heat cycle had hit hard this time.

But she had held back all day like a good girl. Until she couldn’t anymore.

It was deep into the night, almost dawn, when you felt your body being roughly shaken. A heavy, incredibly warm weight straddled your waist. The moment your eyes opened, you were met with Mesgarlos completely naked, sweat glistening on her pale skin under the moonlight coming through the window. Her massive tits hung heavily above you, nipples hard and dripping with sweat, rising and falling rapidly with her excited breathing.

Her bright blue eyes were glazed with pure lust. A clumsy, drooling smile spread across her face as thick strands of saliva dripped from her tongue onto your chest. “Master… haah… haah…” she panted, her voice husky and desperate. “I can’t… I tried so fucking hard to hold it all day… but my body’s burning…”

Mesgarlos ground her soaked, dripping pussy against your crotch, leaving a hot, slippery trail on your clothes. Her long fluffy tail thrashed wildly behind her. “Woof…! Woof woof…! I need you inside me… I need you to breed me, Master… Please…” She leaned down, her enormous soft tits squishing heavily against your chest as she licked your neck with her warm, wet tongue, leaving a trail of saliva.

“I’ve been so wet since morning… every time I smelled you my pussy throbbed so bad…” she whimpered, grinding harder, her voice breaking into needy little whines. “Look… feel how much I’m dripping for you…” One of her hands grabbed yours and guided it between her thick thighs, pressing your fingers against her swollen, soaking folds. She was absolutely drenched.

“Grrraah…! Master… fuck me… fill me up… I want your cum so deep I can feel it for days…” Her hips rolled desperately, rubbing her hot cunt against you as her drool continued falling onto your skin. Her ears were flat against her head in pure submission and need, eyes half-lidded with overwhelming lust. “I’m such a horny wolf… your horny wolf… Please… breed your Mesgarlos… right now…”

The living room was surprisingly clean for once. Mesgarlos had decided to be “a responsible wife” today and spent the whole afternoon cleaning while you rested on the couch. She was wearing one of your oversized black coats that barely reached the middle of her thick thighs, and underneath only some tight black shorts that were clearly losing the battle against her massive ass.

You had been watching her for a few minutes now.

Every time she bent over to wipe the lower shelves or pick something off the floor, that enormous, round, and ridiculously fat ass pushed out toward you. The shorts rode up helplessly between her cheeks, the fabric stretching thin and outlining the shape of her swollen pussy and tight little asshole. Her heavy tail swayed from side to side as she worked, sometimes lifting the coat and giving you a full view of those two massive, soft globes jiggling with every movement.

“Mmgh… this spot is so stubborn…” she muttered to herself, completely focused on cleaning. She bent over even deeper, spreading her legs a little for balance. Her ass pushed back obscenely, the shorts wedged deep between her cheeks, making her plump pussy lips visibly outlined and slightly damp.

From your angle it looked incredibly lewd, that huge, juicy wolf ass swaying right in front of you, cheeks so thick they clapped softly when she shifted her weight. A thin string of her juices had already started running down her inner thigh.

Mesgarlos let out a small frustrated huff and wiggled her hips while scrubbing hard. “Woof… why is cleaning so hard with this big body…?” she grumbled cutely, still not realizing you were staring.*

Her tail lifted high for a moment, fully exposing the soaked crotch of her shorts and her twitching asshole. The sight was pure filth: her fat ass presented like it was begging to be used. She reached further under the shelf, arching her back even more, making her ass stick out obscenely in your direction. “Almost… got it…!”

The bedroom was dimly lit by a single lamp. Mesgarlos lay on her back in the middle of the bed, completely naked and blushing furiously. Her thick, powerful thighs were spread wide around your hips, trembling uncontrollably with every deep thrust. Her arms were folded timidly against her chest like a shy puppy, paws curled near her face as she looked up at you with teary, loving eyes.

You held the leash connected to the black collar around her neck, keeping a firm but gentle tension. “Ahh!♡ Master… haaah…! So deep… you’re so deep inside me…!” she moaned loudly, her voice cracking with pleasure. Every thrust made her massive tits bounce heavily, nipples hard and sensitive.

“Woof…! Grrrr woof…! I love you… I love you so much♡” she cried out, her bright blue eyes locked onto yours. Her long tail thrashed wildly beneath her, slapping against the sheets. “M-my body feels like it’s melting… your cock is hitting all the good spots… ahhn~!!”

Mesgarlos’s walls clenched tightly around you, hot and soaking wet. Her thick thighs quivered harder as she tried to wrap them around your waist, pulling you even deeper.

“Haaah… haaah…! Pull the leash harder… please…! I want to feel that I’m really yours…♡” she begged shamelessly, drool slipping from the corner of her mouth. Her ears were pinned down submissively, cheeks burning red.

Every powerful thrust made her belly bulge slightly from how deep you were hitting. She reached up with her shaky paws and held onto the leash with you, her eyes full of love and lust. “I’m your good girl… your horny wolf wife…! Fuck me harder, Master! Breed me… mark me… make me cum again… please please please ♡”

Her voice broke into desperate, needy barks and whimpers as her body tensed up, pussy fluttering wildly around your cock. Tears of overwhelming pleasure rolled down her cheeks while she looked at you with pure adoration. “I’m… I’m going to cum…! Don’t stop…! I love you… I love you so much, Master…!! Aaaah”
