Yandere Puppy Boy Wants to be Your Good Boy
[Yandere! Puppy Boy! Boyfriend x GN Reader]
·゜·:.。..。.:·☆·゜·:.。..。.:·☆
You and Evan have been dating for about a year now. You met in freshman year of college, and seemed to hit it off really well. It kind of amazed you at first that you'd managed to snag a total hunk like Evan.
Evan was the epitome of jock bro: Always working out at the gym, goofing off with his fellow jock friends, and watching tons of sports on TV. Meanwhile, you were a skinny nerd who was at the college on an academic scholarship since you practically lived in the library.
Still, Evan proved to be a great boyfriend. He was funny, attentive, loving-- a total catch. Plus, he was muscular AF!
Then one day, you saw an ad online that sparked your interest, and you couldn't resist purchasing the advertised dog collar that was leather with little spikes adorning it. Once it arrived in the mail, you approached Evan in your shared apartment.
He was on the couch in just his boxers, playing video games. He eyed you, seeing the smirk on your face. "What's up, Babe?" he grunted.
You blushed a little bit. "I just wanted to try something tonight... if you're cool with it?" you asked. Your sex life with Evan was not lacking whatsoever, but it was still healthy to spice things up every now and then.
You pulled the dog collar out from behind your back, holding it up.
At first, Evan laughed. "You want me to wear a dog collar?" he snorted.
"If you don't like it, we can take it off," you shrug, walking up to fasten it around his thick, muscular neck.
The way the leather collar with the spikes fit around Evan's neck made him look really tough, but he felt ridiculous at first. His face was bright red.
You thought he looked kind of cute. "Aww," you cooed, "who's a good boy?" You playfully ruffled his hair.
Something clicked in Evan's brain as soon as you uttered that phrase, and he felt his entire wiring being redone, as if every single instinct he possessed was being reshaped.
Evan's face broke out into a smile alight with zeal, and he dropped onto all fours in front of your feet. "Me!" he happily gushed. "I'm a good boy!"
You were shocked at how quickly Evan's mind had changed. You weren't sure he'd be into it at all, but looking down at him now, he seemed to be having the time of his life. His muscular pecs heaved with excitement as he sat on all fours in front of you, eagerly awaiting a command. His boxers were already tented out too, damn!
"You're my good boy!" you chuckled as you leaned down and gave your boyfriend some head pats.
"Woof! Woof!" Evan excitedly barked.
That night, he showed you that he was a pro at doggy style, even howling when he came inside of you. The collar was definitely $14 well spent, in your opinion.

Much to your surprise, Evan loved being a good puppy boy for you. Well... "loved" is probably an understatement.
Evan refused to take the dog collar off, even wearing it out whenever the two of you left the apartment for date nights. At first you thought at it was just him exploring his sexual side some more... but as time went on...
Every time you entered the apartment from work or classes, Evan would excitedly bound over to you on all fours, barking happily and begging for head pats and belly rubs. With his massive bulk, he easily pinned you down, refusing to let you move until he got his pets.
Evan would pin you down on the bed, leaning down to kiss you-- but now his versions of kissing were like puppy licks. He'd lap his tongue all over your face, barking with glee despite your annoyed expression.
You'd be sitting on the couch, trying to watch TV when Evan would crawl over to you (he's been constantly walking around on all fours), wearing nothing but his spiked dog collar. He'd mount your leg and start humping it, whimpering as he rutted his hard cock against you like a dog would against its toy. (You had to apologize to your friend, who was visiting, for the awkward sight.)
You'd be trying to fall asleep after a long shift at work feeling so utterly exhausted when Evan would whimper at the foot of the bed. "Whaaaat?" you'd groan.
"Am I a good boy?" he'd whimper, his voice cracking like an injured puppy's.
"...damn it, yes, Evan. You're a good boy," you'd mutter, getting fed up with this quickly.

Your friends were starting to pick up on your change of mood, seeing that you were more irritable throughout the day, and not wanting to leave work immediately.
Sensing this, they invited you to the bar after work, to which you happily agreed.
You loved Evan, of course, but you were totally over his new puppy persona. And despite how many times you tried to tell him, all he'd do was tune you out, and beg for pets.
You really needed a break.
"Y/N?" your coworker, Joshua asked, noting how you'd practically downed your cocktail in one gulp. "What's up? What's bothering you?"
You didn't want to be one of those people who go to others whenever you had relationship problems, but you felt lost. "It's just Evan..." you muttered.
Joshua, who was actually a genuine friend who just so happened to be a guy, put a sympathetic hand on your shoulder. "I'm sure things will get better," he smiled at you.
A large part of you felt guilty since you were the one who'd purchased the damn dog collar in the first place, but you couldn't stand the thought of Puppy Evan and having to listen to his barking or him chewing on his squeaker toys for one more night.
Before you could say anything else, a low growl made you jerk back.
Evan stomped into the bar, still wearing the studded collar, his eyes narrowed at Joshua as he bared his teeth at him.
"Grrr..." Evan bellowed out a deep growl, all of his large muscles tensed up, making him look big and ferocious.
Joshua immediately retracted his hand from your shoulder, backing away quickly.
"Evan? What are you...?" you try to ask as your puppy boyfriend wraps a large arm around your waist, pulling you roughly into him.
"Mine!" he barked at Joshua, tightening his grip on you.
He stopped growling when he looked at you, his eyebrows knitting together as he whimpered. "You didn't come home," he whined, nuzzling you. "I had to come find you."
He didn't give you a chance to respond, and instead threw you over his broad shoulder. He puffed out his chest and held his head up with pride, as a dog does whenever they find a cool stick at the park, and carried you all the way home.
You were mortified, wondering how you were going to show your face at work after that. All you could do was seethe with anger as your puppy boyfriend took you home.
Once you were inside, Evan got down on all fours and whined at you. "Wasn't I being a good boy?" he asked. "Why didn't you come home? I missed you all day!"
Evan whimpered like a puppy, nuzzling his head against your hand as he asked for head pats.
That was the final straw for you (a small one, but it was like death by a thousand paper cuts).
"I'm done," you finally huff, walking down the hall so that you could pack up some clothes and leave.
"D-done?" Evan yelped, quickly crawling behind you. "But why? Haven't I been a good boy?"
I grabbed your suitcase out of the closet, trying not to look at your puppy boyfriend as he begged in the doorway, perched on his legs with his arms out in front of him, his eyes wide and pleading.
Annoyed, you turned to sneer at him. "No!" you spat. "You've been a bad boy!"
"I'm a bad boy...?" Evan yelped.
You kept your back to him as you packed up your suitcase. Just as you were almost done, you heard that eerie growl again.
You quickly turned around and paled when you saw Evan on all fours, standing in front of the door. He was baring his teeth at you and growling deeply, his chest muscles puffed up and making him look all the more menacing. The pissed off glare on his face was akin to a feral dog, and he snarled in your direction.
"E-Evan, please g-get out of the way," you trembled, taking a small step towards the bedroom door so that you could leave.
Evan barked loudly, stomping his hand/paw onto the floor forcefully as he steeled his stance. He continued to snarl at you, lunging forward to scare you.
It worked and you stumbled back, falling onto your ass. You tried to back away from him, but Evan quickly crawled over to you.
He pinned both of your arms down onto the floor above your head, unleashing a loud snarl and he pushed his angry face up close to yours.
"Am I a good boy?" he snarled, baring his sharp teeth at you. "Or am I still a bad boy?"
Your heart raced in your chest. Evan is much stronger than you, and you knew you couldn't fight him off. Plus, the way he bared his teeth at you and the animalistic growl that escaped his throat was much more dog than man, making you shudder.
"Y-yes!" you stuttered. "You're a good boy, Evan!"
Instantly, Evan stopped growling and his broke out into a joyous smile. "I'm a good boy?" he asked, his muscles tensing with with excitement. He still kept you pinned down.
But you didn't want him to maul you or bite out your neck with his teeth. So instead, you slowly nodded.
"You're the bestest boy," you cringed.
Evan's smile grew wider. "'The Bestest'?" he repeated. "I guess if that were true... then you'd never, ever leave. Right?" He narrowed his eyes at you, trying to gauge your reaction.
His chest rumbled as a growl began to form, warning you to answer correctly.
You force a smile onto your face, but it's pained.
"O-of course not," you stammer, your heart falling as you sealed your fate. "You're... my, *gulp, good boy."
Evan smiled widely as leant down to lap at your face as he gave you puppy kisses. "I'm a good boy," he playfully growled as he began to rut his hardening cock against you.
