Pet’s First Reward

(I thank those who participated in my little test now I know I actually have people reading 🥹

Also should I do a aux chapter for inspiration photos of the characters)

Leo walked into his apartment half expecting Saeko to be waiting for him. However much to his surprise his apartment was empty. But this wasn't odd sometimes his step father wanted to take her out to lunch or dinner so she was probably there. So he went to his room to watch the new recommendation he got from Becca.

*Whaam*

After roughly a hour of sitting at his computer and playing with the sliders for the toys he had in Ivy and Saeko there was a loud bang. But instead of being worried or upset Leo just smirked while sliding the sliders for Saeko to max and standing. Leo then slowly walked out the door taking his time as he heard a moan and a thump from the hall.

As Leo turned the corner to Saeko sat on the floor at the entrance to the hallway. Her face was flushed a deep red as she looked up at Leo pleadingly. One hand on her abdomen and the other reaching in to the booty shorts she was now wearing. She had on a white tank top that was already starting to stick to her skin and her collar adorning her throat that had a heart on it.

"Master please *Ahnnn* give it to *Ahnnn* me. Your toy needs your *Ahnnn* massive cock." Saeko begged as she moaned as she leaned backwards to show her drenched pussy to him. She pulled her shorts to the side to the best of her ability partially exposing herself. Leo could see the toy in her urethra had expanded greatly. The visible part of the toy was now 2.5 inches across and if the bulge on Saeko's stomach showed anything both it and the one in her ass were fairly deep.

"You aren't a very good toy the first thing out of your mouth is you asking for a reward." As much as Leo desired to do just as she asked he knew despite the state she was in they would both enjoy themselves more if he was more forceful and took his time. Leo slowly walked forward as he pulled out a leash and her collar changed into a thick slave collar. As he reached her he latched the leash and pulled her up.

"A good toy must work for her reward. Now be like the good girl you are and walk to the room." Hearing his words Saeko smiled brightly as she shakily crawled to the bedroom at the end of the hall. Leo fallowed behind her as he pulled up on the leash that was now between her legs causing it to dig into her. Saeko left a trail of juices down the hall as she moved. Her ass shaking back and forth like a happy puppy going on her first walk.

*Ahnnn* *Ahnnn* *Ahnnn*

The hall wasn't long but between the toys churning rapidly inside her and the leash digging in her clit her body shuddered lightly with every movement she made forward. As they made it to the entrance of the room Leo yelled. "Heel!" She stopped at his order and sat on the floor in a crouched position. Leo walked past her and sat on the edge of the bed.

Leo then pulled the leash hard yanking her forward slightly as he ordered. "Come tell me how you time at work went before I decide if I should reward you or not." Saeko quickly crawled to sit between Leo legs her face a stopping a foot before his crotch. As she sat on the floor she stared at the growing bulge straining his pants as she gulped spoke.

"Working was hard *Mnnn* the presents you gave me *Mnnn* have filled my holes so much. *Ahnnn* My insides feel like they are *Mnnn* going to break." To empathize this she pulled her shirt up to show her stomach. There were 2 bulges on her stomach one smaller one stopping just below her navel and a massive one almost reaching her ribs. The toys still shook vigorously stretching her already taunt stomach.

"For some reason *Ahnnnn* my hole body is extremely sensitive. *Mnnn* My chest also feels tight and swollen. *Ahnnn*" Saeko fully pulled off her shirt revealing her breast that were noticeably larger. The beautiful pink tips looking slightly engorged. Removing her shirt enticed a moan as she continued. "*Ahnnn* They have become to big *Mnnn* to fit in my bras any more."

Leo reached forward and started to fondle them as he spoke. "That's because I want you to be my perfect toy. I'm going to train you to be my perfect personal hole." Leo firmly squeezed her right breast and as if to prove a point her breast started to spray milk. "Every part of your body will be molded to my liking." Leo bent forward and placed a gentle kiss on her lips as he continued to milk her breast and starting on the other one.

Breaking away after a long moment Saeko stared into his eyes as she confirmed. "*Ahnnnnnnnn* Yes Master *Mnnn* this toy is yours to mold to you liking. *Mnnn*" Saeko started to massage her own breast as milk flowed like a river. "Good girl. Why don't you show me how much you deserve your reward." Leo spoke while stroking her face lovingly his milk soaked thumb parting her lips and entwining with her tongue as she licked it clean.

Finishing with Leo's thumb she turned and showed her ass to Leo while pulling off her shorts. Saeko's huge ass jiggled as she shook it back and forth to entice him. Her folds glistened as juices flowed down her legs to the waiting puddle beneath. The things however that drew the most attention was how her ass and slit were held agape by the toys buried deep in her. The toy in her ass holding her cheeks apart had the entrance spread apart by 3 inches and the toy in her urethra had reached a massive 2 and a half.

Looking at the sight Leo grabbed the toy in her ass and started to pull. *Shlorp* *Ahnnnn* *Pop* Leo watched as the toy longer than his forearm popped free of her rectum having dragged her walls out with it before she clenched and they went back in leaving her ass gapping. Her asshole opening and closing as it begged to be full again. "Such a greedy little hole. To fit such a large toy it must love being stretched." Leo laid the toy across her back to show how deep it had gone.

Feeling the toy reach her mid back Saeko couldn't help but feel slightly embarrassed as she spoke. "Your toy's body wants *Ahnnnn* it's master to fill every nook with your seed *Ahnnnn* so it did it's best to fulfill your desires." With her ass now empty the toy in her urethra had more room to twist causing it to be visible from Saeko's gaping hole. "Maybe I should reward this slutty hole then since it worked so hard. But first let me check how this your slutty little ass has developed." *Ahnnnn* As Leo spoke he used his fingers to tease her gaping entrance before shoving his fist up to his wrist in her. *Ahnnnn*

Leo slowly twisted his arm back and forth as he slid his arm deeper his forearm slowly being devoured. Saeko's arms lost strength and her face hit the floor and she slid back making Leo's arm go in to his elbow. *Ahnnnn* "I was right about this greedy little hole there was no struggle." *Ahnnnn* *Shlorp* *Ahnnnn* Leo started to thrust his arm in and out. *Ahnnnn* *Shlorp* *Ahnnnn* His thrust picking up momentum as he moved his arm inside her. *Ahnnnn* *Shlorp* *Ahnnnn*

*Ahnnnn* *Shlorp* *Ahnnnn* *Pop*

Low pulled his arm free as he gazed at Saeko as her ass gaped and her eyes had rolled back. "Ha I barley used it and you are already like this lets try your other hole." Leo stuck 4 fingers in her ass and his thumb in her pussy as he grabbed the remaining dildo in her urethra. Instead of pulling it out Leo shoved it deeper and turned it on max. Saeko's stretched pee hole closing tightly around Leo's index finger.

*Ahnnnnnnnnnnnnn*

Leo used his fingers to push on her womb through her walls into the spinning toy. Saeko in response started to convulse as her hands clenched into fists by her head. *Mnnnnn* "Even this hole is greedy I can't even see it anymore. Despite having stretched so much it's holding my finger like it doesn't want to let go. Push it out for me I want to see it." *Mnnnnnn* Saeko pushed with all the strength her body could muster. *Ahnnnn* *Shlorp*

Unfortunately her hole didn't want to let it go as the toy went back inside her when she relaxed for a moment. Her urethra closing tight again with it's return. Leo proved his hand in her ass as he spoke. "Try again I'll help this time. However if you don't get it out we will stop here for the day." His words caused her to panic as she quickly reached behind and spread her pussy as she began to push.

*Mnnnnnnnnnnn*

Saeko's urethra spread slowly at the toy made it's way out. Leo used her womb to apply pressure to help push out the toy her stomach bulging deeply as he applied great pressure. The toy spun as it slowly inch by inch worked its way from deep insider her. The vibrations caused great pleasure making her want to reduce her strain. But the fear of Leo not touching her made her persevere.

*Ahnnnn* *Shlorp* *Ahnnnnnnnnnnnnnn*

With a final push the toy slipped out and onto the floor. The toy having curled inside her had reached a massive length of 18in filling her completely. Now with her hole free Saeko collapsed back on the ground her ass held high as bouts her now empty holes gaped for air. "Good girl." *Smack* Leo praised while smacking her ass causing her holes to clench tight before loosening once again as Saeko panted in a mix of her own fluids as they ran down her legs and leaked from her breast.

"Now would my good girl like to pick her reward or should I chose myself?"

(I'm giving the option to pick a reward to y'all if you want to I'll pick the one I like most.)
