A collar and leash

Rose sat quietly on the floor as her family the Dursleys talked about what they wanted to do with her next while trying to ignore the feeling of the butt plug in her ass.

Petunia pulled a collar and leash out of the box next.

"This will be her collar!" Petunia said to Dudley putting it around Rose's neck while attaching the leash to it "This is meant as a restraining collar for dogs to teach them to obey their owner”.

“And this will allow you to control where she goes,” Vernon said taking the collar and pulling Rose towards them.

"There you go girl," Vernon said petting Rose's head and then petting her butt "See? She's becoming so obedient already”

As Vernon and Dudley played with Rose's new leash Petunia continued her instruction

"Ok then I need to teach you both how to properly milk the bitch” She said “We'll start with the basic method first which means with your hands”

Rose secretly felt a rush of joy at hearing that as her breasts were starting to feel engorged.

“First we need to put a bowl under her tits so the milk doesn't get on the floor,” Petunia said walking to the cupboard and coming back with a 45-ounce soup bowl.

Petunia sat down and gestured for Vernon and Dudley to do the same.

“Now Dudley” Petunia said “ Look at me how I grab her nipples and start squeezing them and then pulling down, first one then the other"

Rose starts getting aroused by Petunia milking her tits.

She wants to say something but she knows that now that she's the family pet she must not talk in any way unless spoken to first.

"See? If you look at her pussy you can see that she likes this” Petunia said “Now it's your turn, Dudley"

Dudley grabs Rose's nipples and starts pulling them down one and then the other Rose's arousal increases and her nipples become very hard.

Petunia smiled "And Dudley since her milk is supposed to be used for human consumption it can be drunk straight from the source let me show you how to do it properly" She gets down under Rose as Dudley backs away and starts sucking her hard nipples "See? You just need to suck and bite a little to pull the milk down to you and then you can drink it”

“Now give it a try," Petunia told Dudley

Dudley got under Rose and starts sucking her nipples who got more aroused feeling Dudley's teeth biting her

Damn, she needed to cum so hard right now.

Soon both Vernon and Dudley went to milking her each of them pulling on a nipple.

After about ten minutes of milking Rose could still feel plenty of milk in her breasts and Dudley started to yawn.

“Geez Mom,” He said “Is there a faster way to milk her than this”.

“Yes, there is,” Petunia said “I ordered an industrial cow milker but it will take a few days to arrive so until that comes we have to milk her by hand”.

“If you're getting tired though Dudley” Vernon said, “We can always have her hand express her milk into the bowl for us”.

“Good idea Vernon,” Petunia said and she slapped Rose's ass “Use your hands and milk your breasts into the bowl,” She said “Be careful, and for every drop I see that lands on the floor that's five spankings you get”.

Not wanting to get spanked Rose carefully pulled on her nipples and milked herself into the bowl for the next ten minutes or so until she felt that her breasts were empty.

Petunia roughly felt Rose's breasts and pulled on her nipples and when nothing more than a few drops came out she nodded in approval.

Picking up the bowl of milk Petunia took it to the kitchen to measure it.

“That's about 25 ounces over the course of 20 minutes,” Petunia said “More than an ounce a minute that's impressive bitch”.

Petunia looked at Dudley “Now in about another hour or hour and a half her breasts will refill so we need to milk her again”.

Dudley sighed “With fun comes responsibility I suppose” He muttered.
