Domming Ryoubi

You and Ryoubi had started getting frisky after dinner, and now here you were in your bedroom, as Ryoubi straddled you after she tore off your shirt.
"You damn horny dog. Who do you think you are, getting so erect already?" she chided as she smirked at you, having undone the button on your pants and pulled down your boxers to let your erect dick sway freely in the cool air of the bedroom. "What? Are you going to cum so soon?" she said as she started grinding on your dick, having removed her panties from under her skirt earlier. You're slowly being driven crazy and could reach your limit any second now! With only one thing in mind, you reach for Ryoubi's ass and grab on, starting to knead and spread it around as it's softness conforms around your fingers and Ryoubi gasps! "You damn horny dog, get your hands off of there!" You don't stop! You keep kneading and squishing, and Ryoubi's starting to lose her cool! "S-stop! Stop it!" She's starting to get tears in her eyes as her moans and gasps start becoming more frequent! She's stopped grinding as you start to sit up and pull her closer towards your chest. You speed up your kneading and start getting more intense! "S-stop, ple-eeease, sto-aah!" She can't handle it, and she falls forward onto the bed as you pull out all the stops! Kneading that plump softness around like the world's finest dough, squishing those cheeks that are as soft as pillows! Suddenly, you get an idea. You stop kneading as Ryoubi starts to calm down and stand up and look towards the dog collar and leash on the doorknob. Ryoubi kept it there for when Ryouna would come over and beg for a domming session. You grabbed it and quickly closed the collar around Ryoubi's neck as she finally started to calm down from your butt massage. "W-what the hell are you doing you idiot!? Get this stupid collar off of me, I'm not a damn dog like you!"
With a smirk, you gave the collar a light tug with the leash, causing Ryoubi to let out a small squeak.
"Now now, that's not the kind of tone that a dog should take with their master, now is it?"
"EXCUSE ME!? If anyone's the dog here, it's yo-aaah!" You'd quickly snaked your hands around to Ryoubi's backside and started massaging her ass again.
"As I've said, that's not the kind of tone that a master wants to hear from his good little dog. Now, what were you saying?" Ryoubi had started letting out a small whine at the gentle motion of your hand on her ass, a powerful blush breaking out across her face.
"R-ruff ruff."
"Good pup! Now, for your reward!" You intensified your massage, grabbing, pinching, prodding, and kneading Ryoubi's cheeks, your hand occasionally drifting to trace over her pussy. With your other hand, you started to tug slightly on the leash again. "Now who dressed you up in these clothes? Dogs don't wear clothes, you're probably suffering in those! Here, let me get those off of you..." You unzipped her skirt, exposing her lower body as her blush reached a new level of brightness. It took some finesse to take off her shirt, but you managed, and now Ryoubi sat on the bed before you, naked. "Hmm... It seems whoever dressed you up in those horrible clothes had the common sense to not put a bra on you. Clothes are one thing, but lingerie on a dog? That's just silly." Ryoubi just continued to scowl at you as her face turned as red as a tomato. You smirked, and patted her on the head as you put more force into the leash to get her off the bed and onto the floor. Bringing her to her knees, you stuck your hand out in front of her face. "Now, shake." Ryoubi gave you the meanest scowl you'd seen of the night, but to your surprised, she slowly brought her hand to meet yours and shook it. "Ruff ruff." She muttered under her breath. You knelt down onto one knee and gave her a kiss on her forehead and ruffled her hair. "That's a good girl."
You brought your free hand to her butt again and gave it a small squeeze as you noticed that Ryoubi's scowl had vanished at some point.

Now it was time for the next test of your dog's loyalty. You sat back on the bed, and motioned Ryoubi to climb onto it and kneel with the leash. "Now it's time for a treat." You stood up and positioned your erect member in front of her face. "Dig in, my little pup." Again to your surprise, Ryoubi brought her mouth towards it with little resistance. Slipping her mouth around your member, she began to suck on it, bringing her head up and down as she did so. Whenever she'd reach the tip, she'd pause to give it a small lick or nibble before continuing her fellatio. You were quickly reaching her limit with her teasing, but you couldn't finish so early. Forcing Ryoubi back onto the bed, to her surprise, you stripped off your boxers and pants as you brought Ryoubi up to your face, meeting her eyes. "Who said I wanted you to face me, you horny bitch?" You tugged a bit harshly on the leash, and Ryoubi let out a small yelp as she quickly flipped onto her front. "Good! How else would I fuck my dog, other than..." You found her lower lips with your dick, and jammed it forwards. "...doggystyyyyyyyyle!" you screamed as you felt yourself penetrate her. You and Ryoubi thrashed wildly in your love-making, you grabbing onto her hips to keep yourself from pulling out while Ryoubi kept "ruff"-ing and squealing. You both kept wildly thrusting into one another as you felt yourself nearing your climax. Leaning forward, you released your grip from her hips and hooked your arm around her waist to bring her into an embrace as you whispered into her ear. "I love you, my little pup." With how close to you were to her face, you finally got a good look at her expression of pure love, lust, and slight humiliation, and you swore you saw hearts in her pupils before you nuzzled your face into her neck and finished.
Ryoubi let out the loudest shout of the night as you finished together. "W-WAN WAAAAAAN!" If your neighbors weren't awake before, they probably would be now. The sheer exertion you felt from fucking Ryoubi caused you to release her and collapse next to her as she herself collapsed onto her front. With the both of you gasping for air and dripping with sweat, you turned onto your side to face her and pull her into an embrace again. You gave her another kiss on the forehead, before trailing down along her face to meet her lips and giving her a deep kiss. You pulled your lips away eventually and whispered to her again. "I love you, Ryoubi. More than you'll probably ever imagine." She simply smiled at you warmly and responded, "I know. I love you too, Anon." Then, she gave you a devious smirk and said, "Just don't think that you'll get me to do that little show again anytime soon."

You and Ryoubi had laid in bed for a long while after you had both finished, cooling down and relaxing after the intensity of your love-making. Snuggling in one another's naked embrace, you realized that Ryoubi still had the collar and leash around her neck. Feeling your libido start rising again, an idea popped into your head as you started untangling from Ryoubi. "Now what, Anon?" Taking the leash into your hand, you found your pants and a jacket and threw them on as you started pulling on the leash to bring Ryoubi out of the bedroom. She followed you towards the door on her hands and knees before she suddenly stopped as the realization of what you wanted to do dawned on her. "N-no, no way, Anon!" Turning to face her, you knelt down and took her face with your free hand and met her eyes. "Now now, my little pup, I wouldn't do anything to hurt you, and you know that. Now, come along, it's time for your night walk." Ryoubi kept her eyes locked on yours, and you could tell that she was afraid of being caught in such a compromising position based on how she was quivering at your touch. "My little pup, I promise you, with how late it is, no-one will see us." Ryoubi kept her eyes locked on yours for a while longer, before sighing and looking away. "Fine, but you owe me big time..." "I'm sorry, what was that?" "Ruff ruff..." Satisfied, you opened your front door and stepped out into the frigid night, leading Ryoubi out of the doorframe so you could close the door. Ryoubi started shivering, goosebumps breakout out across her bare skin from the cold and excitement of her naughtiness. Bringing your hand down to her bare back, you stroked along her spine and down to her ass several times to calm her down, feeling your fingers brush along the bumps as you did so. "You'll be fine. I promise." And with that, you had your little pup lead the way into the night, taking her on a short walk around the neighborhood.
