autor’s notes ᯓ this is my first fic here. keep in mind english is not my first language so i had to use help from a translator! hope y'all enjoy some of my thoughts on the puppy!jo agenda.
Jo was shy. Extremely shy. So, in your sex life, you didn't expect anything different from him. Sex with Jo was teeth rotting sweet, rarely taking risks and never springing sudden experiments on you. Shy pecks stolen during missionary, eye contact that revealed a small smile at the corner of the boy's lips and made Jo's big ears turn red and warm. So when you innocently checked Jo's search history and found extensive wikis and blogs about "How to introduce pet play to my partner," you were more than surprised, you were… actually wet.
Wanting to spice things up, you started planning. Maybe using themed lingerie with little tails and ears would work? But no, nothing changed dramatically... Jo continued with his usual shyness; he absolutely seemed like he had questions to ask, but he must have ended up keeping them to himself. Noticing how normal everything still was, you, being a very attentive girlfriend, beginned to explore similar wikis, finding topics that interested you, and eventually falling down a rabbit hole about male pet play and how to tell if your partner has that kind of kink. That sparkled something hungry in you, and you absolutely knew you had to try it with your boyfriend.
It started with a "good boy" here and there, in everyday life and sometimes in bed. Jo didn't seem to understand why you were calling him that, but he was happy anyways with the praise although his ears didn't show any particular unusual color. Growing impatient, you decided to get straight to the point. You bought a pet collar from a proper website. Now, how would you introduce it to your boyfriend? The huge one that still blushed after years with just a unexpected kiss? It had to be during it, or he would probably hide and die from embarrassment.
...
So, during a makeout session, the kiss between you grew sloppier until you stopped him and looked into Jo's doe eyes, making your already wet pussy throb beneath your panties.
"Jo."
"Yeah?"
"Can I ask you something a little… strange?" you said, slightly out of breath.
"Of course, my love" the boy replied innocently, stealing you a quick peck.
"Promise you won't get embarrassed?"
"I can't promise that, darling, but I can try”
Of course he couldn't promise that, after all, he was still Asakura Jo.
"Can I put this on you?"
You gently pulled the item from the bedside drawer: a baby pink collar with a leash attachment.
...
"Baby?"
Jo's eyes were almost shut, his mouth was slightly open, his ears impossibly redder than usual, and a damp spot had formed on his boxers. His hard cock looking ready to burst right through the fabric. Noticing, you chuckled quietly, trying not to make your shy boyfriend explode. "My handsome little puppy~ you really like this, huh?" You praised. Hearing the petname, Jo thrusted his hips upwards unconsciously, desperately searching for friction, letting out a delicious moan as the collar was properly put around his neck.
"P-please Y/n, just… fuck–"
Those words coming from his mouth surprised you just as much as they had surprised him. His face was flushed, his half-lidded eyes looked directly at you and his underwear, once damp, was soaked with pre-cum, tight around his cock.
"Calm down, puppy. Impatience won't get you anywhere~" you teased, climbing off Jo's lap before pulling his boxers off in one swift motion and positioning yourself directly over his dick.
"First, say you're my good boy. Say it to your owner"
"Hah... I'm your good boy– Please fuck me, Master…" Jo whined. You dropped down all at once onto Jo's large cock, feeling your cunt do a biiiig stretch around him. As you bounced up and down on the boy's cock, you tugged on his collar, making your once quiet boyfriend let out even more beautiful sounds.
"Thaaat's it, just like that. What is my good little puppy going to earn for making his owner feel so good riding him?"
Jo was already completely gone, only capable of babbling "M-Master, you're so good to me..." and whining nothings on your ear. You bounced precisely on his cock, succeeding to make him hit your perfect spot repeatedly, forming a white ring around his base and making you moan even louder.
"Ah pup, I'm cumming!" your pussy squeezed him tighter, getting ready to milk him at the same time. You were treating Jo’s body like a plaything, and he was loving it. His hips, previously limp, sprang back to life when he heard that from your lips, driving him to relentlessly hit your G-spot while you came all over his cock. “Baby, I’m gonna cum, I’m gonna cum! IloveyouIloveyouIloveyou” Jo released his load inside you as he shuddered, mixing your fluids together.
…
After lying on top of the boy for a few minutes, you gently opened your eyes and slid off your boyfriend’s cock, finding Jo asleep with an impossibly innocent expression after the session. You let out a soft, proud laugh at your giant boyfriend, who, in that moment, looked so small compared to you it was startling. You got up to clean yourself and grab a damp towel for your sweet boyfriend, returning to the bedroom, you found Jo still cutely sleeping at the bed. You cleaned him up tenderly and then joined him, only to be surprised by a tight hug. “I love you, pretty” Jo murmured, half-asleep. “I love you more, my little pup”.
