Next stage of training
Dog Training
“Natasha, you have proven yourself to be a qualified toilet, now we can progress to the next stage.” said Brian. “Stand up, toilet, report to this line.” said Brian standing in front of Natasha
Natasha regains her strength and stand up as requested.
“Good, now stand with feet apart and hands above your head. “ order Brian.

Natasha follows his orders.
“Stand still and don’t move, Jack will prepare you for your next position. “ said Brian “In the same time, I will give you a brief updates of the mission. I hope you won’t piss on the ground like last time.”
By hearing this worries Natasha, she doesn’t know what is Jack up to this time or what kind of sex position she will be fixed for her toilet service.
Jack is squatting behind Natasha’s ass, thrusting through Natasha’s butt hole with his finger. Natasha’s butthole is roughly spread by Jack’s finger, she doesn’t feel comfortable at all, she tried her best holding her moaning voice and her body still.
“Here’s our current update of the mission'' starts Brian ''First part: we have successfully find the arms dealer in the prison, he is still breathing. Like I said last time, we need the data that he is carrying, we will set up a plan for you to get into the prision.” said Brian
It seems like Natasha’s butthole has finally loosened enough, Jack then patted her ass cheek, signaling Natasha to kneel down on the floor. ''So it is doggy style this time?'' thought Natasha
“Second part, we have successfully arrange a Caedelis smuggler. Our intel said that this smuggler used the cargo ship: the Lemurian Star for shipping its contraband, this will be your opportunity to get on the ship, we are currently waiting for the smuggler to get contact with us. Any further plan of the operation will be updated to you when it is ready. “ said Brian finishing up his briefing “Now let me introduce you some equipment for your current training.”
At the same time, Jack slightly pushes Natasha forward from behind, making her on all four.

Natasha thought they are going to restrain her with a new bondage for the toilet service as they cuff her ankle and wrist with two pair of straps. However, she suddenly feels a cold metal touching her asshole. At the same time, Brian takes out a ball gag and secure it to Natasha's mouth. While Brian tightens the straps of the gag to her head, Natasha cannot see what happens behind, she can feels the plug penetrating her butthole and making its way into her rectum slowly and steady.
Natasha moans from the stimulation of her ass. When the moaning sound comes out her mouth, it somehow became clear barking sound. “Woof~Woof~” Natasha is socked by the sound, before figuring out what just happened, Jack makes a final push of the plug, making it fully stick into her ass which also cause her another wave of pain.
As Brain released Natasha’s head, she quickly turns head back to see what’s going on with her ass. She sees Jack has inserted a dog tail for her. “Woof~Woof~Woof~” barks Natasha as she tries to scream.
Besides the gag that turn her voice, Natasha also discover the tail will swing sideway evertime her ass muscle contracts.
With the tail and the gag, Natasha looks like a dog pandering to her master. “What a good device, it can turns all her voice into dog barking sound. haha~~~” said Brian “Look how happy and energetic our puppy is with her tail shaking and her clear barking.”
“Yeah, she is now in fact an actual puppy. am I right? Natasha” said Jack
Natasha can only protests against his actions by replied to them with another barking.
“Oh, here’s your reward for your good behavior for the last couple days and a gift for your new life” said Brian. He takes out a dog collar with Natasha's name engraved on the name tag hanging on side of it. Brian then puts the collar on Natasha's neck.
When finished, Brian and Jack take a step back and admiring their pet with satisfaction. ''Let us begin the dog training'' announced Brian ''Our goal is to train out an obedient pet.''
''Oh really, obedent? How ?'' asked Jack
“Well, hehehe~ Let me give you an example: If I ordered our little doggy Natasha to piss in public right in front of people, she will strip naked immediately and pissed on the floor with one of her leg up right away. Then I will considered she is a qualified dog'' explained Brian
''Let's don't waste time and start our training'' said Jack. He takes out a bone shape rubber toy and throw it away.
''Bring the bone back'' ordered Brian.
Natasha nods silently and crawl toward the bone. With every step she crawl, her ass will twitch involuntary causing the tail starts swinging, like a real dog shaking it's tail.
When she arrives at side of the bone, just as she is about to pick it up. Jack voice coming from behind. ''Wait a minute, Natasha, Have you ever seen a dog picking up things with it's hand?''
''I can't use my hand? How the hell am I gonna pick it up?'' thought Natasha to herself, she is informed not to use her hand also her mouth is shut by the ball gag.
''Bitch, Doesn't you have one more hole free?'' said Jack will a strange smile
By hearing this, Natasha signs hoplessly, she clenches her fist like a dog palm, use it to pull the bone toward her bottom and insert it to her pussy . Natasha's pussy is stretched open little by little by the dog bone. Natasha then squeeze her vagina tight, making sure the bone will not fall off as she slowly crawl her way back to Brian.
Natasha is naked and on all fours like a dog, barking and crawling slowly towards the two men. The dog's tail stuffed in her asshole waggled as she crawled. It makes people want to get closer and watch the lewd look of her asshole being stretched open.

''Good girl'' said Brian, watching Natasha hands over the bone with her pussy.
