James was in his way home, carrying a hamster cage with his aunt Cathy inside of it, that he has turn her into a large white pig, her pig form was fat and her 7 pairs of breast were bigger than the normal pigs use to had and of course, right now she was the size of a big rat while she was trapped in the hamster cage, that it was going to be her new home as her nephew has stated before. At this moment Cathy was just laying there on the floor of her cage that has the usual substrate surface, she has been crying in silence as the tears were coming out her eyes, wondering if she ever would be human again, as the thoughts of her old life were coming to her mind, remembering the beauty that she was at her age and the nice and sexy figure she used to has, but now, she was just a small fat piggy inside of a hamster cage.
As the time passed while James was walking, he finally reach to his house, after he enter in he call out his mom, Marie, she was a woman at her 40 years old, long brown hair with a nice figure, she replied to James that she was in the kitchen as James go to were his mother was, carrying his piggy aunt still inside of her cage, he noticed that Marie was making a cake and she look to her son smiling to him.
"Hi mom." said James.
"Hi honey, how was your walk?" replied Marie to James.
"It was nice, here I got a surprise for you..." said James showing the hamster cage with Cathy in to Marie. "I saw her in offer at the pet shop, what do you think?" said James smiling.
"Marie?..." said Cathy as she saw Marie's face that look at her, she quickly stand up in her cage and closer to Marie. "Marie! Is me Cathy! Please you have to help me, James turn me into a pig and shrunk me to this size, tell him to turn me back to normal please!" shout Cathy pleading to Marie.
"Awwww, is she not a cutie? This is one of those mini pigs right?" said Marie smiling looking to Cathy.
"I'm not a mini pig! I'm your sister in-law! Stop looking at me like if I'm some cute animal and help me!" exclaim Cathy to Marie.
"That's right..." said James as go to the table and put the cage on it, and then he take out Cathy of it to show her to Marie with more detail. "She was alone in the pet shop, I took pity of her and I buyed her, she was also in a cheap offer, I think I can give her a better life here." said James looking down to Cathy in his hands.
"Oh I have such good son with a caring heart..." said Marie to James and look to Cathy. "But isn't she a little too much...fat?" said Marie as she touch Cathy's belly from her left side with one finger.
"Hey! Stop that Marie!" shout Cathy upset as Marie was touching her.
"I guess loneliness can make you eat too much don't you think?" replied James joking around.
"I'm not fat!" exclaim Cathy.
"I think so..." said Marie giggling a bit as she start to rub Cathy's hair. "So, what's the name of this chubby girl?" ask Marie to James.
"I named her Cathy, for aunt Cathy." said James as he laugh a bit.
"Oh James, don't be like that with your aunt." said Marie as she laugh of her son's 'joke'
"I don't think she would care much about it if I name this cutie with her name, right Cathy?" said James as he rub Cathy's back a bit with one finger.
"Please James stop." plead Cathy to James feeling the humiliation.
"I see..." said Marie then she move her finger and starts to touch Cathy's curly tail. "She really is a cutie little piggy." said Marie giggling.
"Marie please don't touch my tail! I'm very sensitive there!" exclaim Cathy as she was getting excite by Marie's touch.
"Wait mom, don't touch her too much there...She, got a 'accident' at the pet shop." said James to Marie.
"Ewww, I see..." said Marie as she quickly remove her finger from Cathy's tail. "Poor little thing, you have to clean her properly ok? And don't forget to wash your hands too." said Marie to James.
"Sure sure." said James with a smile and he go back to the table and put his aunt back to her cage.
"Wait, no! Marie please you have to help me, I'm not a pig! I'm Cathy!..." exclaim Cathy desperate from her cage pleading to Marie as James carried the cage with him as he was leaving the kitchen, "I'm Cathy!..." yell Cathy to Marie with tears coming out her eyes but James go out the kitchen with her. "Ja-James...Why Marie doesn't listen what I say?" ask Cathy sobbing a bit to James as she looks up to him.
"You are very slow right? I said it before, that I'm the only one that can understand you." replied James while he was walking with Cathy in her cage.
"Where are we going?" ask Cathy to James.
"To the bathroom, you need a bath you dirty piggy," replied James with a smirk looking down to his aunt and she doesn't like one bit the way James was looking her.
When the pair entered in the bathroom, James take out Cathy of her cage and leave her in the sink and he open the sink's faucet and let the water stream over his aunt, the water was cold, so Cathy let a out squeal as she shivers but then James lower her hands to Cathy and starts to rub her body a bit, then he take her out the sink and he grab a toothbrush as he cover the bristles with soap, when it was ready, James starts to rub the toothbrush on Cathy's body, at first she feel embarrassed by the fact that her nephew was washing her in this way, but the feeling of the toothbrush on her skin and the way James was treating her, she couldn't no resist and starts to enjoying the moment.
"Mmmmm this doesn't feels so bad, at least I'm getting something good of this weird day." thought Cathy smiling.
Then James carried his aunt covered in soap back in the sink and wash all the soap of her body, when James clean all the soap of her body, he again take her out the sink, Cathy thought that James was going to repeat his action with the toothbrush, but instead he opened the cabinet over the sink and take out a box of cottom swabs, when Cathy look at te box in his nephew hand, her face got pale of fear.
"Ja-James! Wh-what are you gonna do with those?" said Cathy scared to James.
"Oh well I just gonna use one of these to clean you properly." said James with a smirk as he take out one cotton swab of the box.
"You don't mean that...No! Please! James don't do that to me! I'm begging you please!" exclaim Cathy scared as she was trembling.
"I'm your owner and I have the last word here piggy." replied James as he lower one hand to hold Cathy.
Cathy, knowing what James was going to do with her, she start to struggling to get free of her nephew's hand, but it was in vain, she was too weak to beat the force of her giant nephew, then James put his piggy aunt in position with one hand and with other he has the cotton swab that was coming closer to Cathy's butt, Cathy was screaming, pleading to James to stop, but he wasn't hesitating and suddenly, James inserted the tip of the cotton swap in Cathy's anus, she let out a squeal of pain but James continued and he rubs the tip of the cotton swap in the walls of Cathy's anus as James was going deeper in her.
Cathy at first was feeling the pain of her anus being penetrated , but as the seconds passed the feeling become pleasure arousing to her as her pussy was getting wet, when James finished, he take out the cotton swab of Cathy's anus, she was panting right now as her mind was in conflict, she was glad that the cotton swab was out her but she was frustrated by the fact that she was so horny right now and she haven't reach to the climax, James look to the cotton swab and saw the fragments of shit on the tip that he inserted in his aunt's butt, then he discard it to the trash can and look down to his aunt.
"Well your butt is completely clean, I think, lets resume washing your body." said James to Cathy.
"How could you? How can you do that to me!" yell Cathy angry to James with a deep red blush on her face.
"Oh please, it wasn't so bad, or are gonna tell me that you have never do anal?" said James mocking Cathy.
"No! I never have done such thing! Why do you think that I'm so angry? You raped my butt you, you..." shout Cathy angry, also revealing this fact to James, then she looks down and starts to cry in sorrow.
"Hey hey..." said James feeling regret as he hold his aunt and lift her closer to his face. "I didn't mean to hurt you in that way, I just want to punish you for being...such a cunt, I didn't think that I would hurt your feelings that badly." said James saying sorry to Cathy.
"If-if you re-really feel so-sorry for me, then ma-make me human again." replied Cathy between sobs as she look to her nephew's face.
"No, you haven't done something good enough, to deserve being human again." said James in a simple tone as he looks to his aunt's sorrow expression on her face.
"You-you mo-monster! Why are so-so cruel with me?!" yell Cathy to James as she was going to start her cry again.
"I'm your owner, as I can be mean to you, I also can be kind and gentle with you." replied James to Cathy.
"Wha-what do you me-mean?" ask Cathy looking at the smile on James, but he was not looking her with a mean smile like before, this one was more...naughty.
"I wish for you breasts to grow a bit more." said James while he was holding Cathy, then suddenly her 7 pairs of teats grow to the point that they were almost double in size.
"Eh?..." said looking down to her breasts. "James? Why did you make my tits bigger?" aske Cathy confused.
"So I can do this." said James as he move Cathy closer to his face and then James open his mouth to caught in a pair of Cathy's teats and he start to suck them.
"Ooohhhh!...James!...Stop!...I may!...Be a pig now!...But!...I'm still...Your aunt!....Ohhhhh!" exclaim Cathy trying to protest against James actions but she was moaning in pleasure.
At this moment, James was sucking and licking all the teats of Cathy, he was doing this in a gentle and soft manner, this treatment for his aunt was too much, she stopped telling to James to stop doing this to her and instead was asking for more, while her pussy was soaking wet, James noticed this and move one finger to his aunt's vagina and start to caressing her there, by doing this, Cathy was moaning louder, it doesn't take him too much until finally James make his aunt to cum, Cathy at the moment of her climax she let out a squeal of pleasure as she shoots a stream of cum out of her pussy down to the sink, after this Cathy was panting tired and satisfied while James was still sucking her teats until he stopped.
"Mmmm, your milk is warm and sweet Cathy, very delicious..." said James looking to his Aunt. "That wasn't so bad isn't it?" ask James to Cathy.
"James...That...Was...Wonderful...Ohhh." replied Cathy in ecstasy between her pantings.
"See? I told you, I can be a nice owner with you, piggy." said James to Cathy.
After this, James continue bathing his aunt, this time without doing anything mean or naughty to her, when he dry out her body with a towel, he leave her again inside her cage, Cathy was so tired after James had give her the best orgasm that she has feel in her life, in other situations, she would have feel disgusted, but what she had feel was so good and satisfied for her, that she just stay there laying on the surface of her cage, almost forgetting the current situation that she was, then she closed her eyes falling sleep while James was carrying her cage to his bedroom.
