Exercise

“You need to start taking more initiative,” Petunia said to Rose “Now that Vernon is done fucking your ass I want you to start by inserting your tail yourself”.

Rose obediently took the tail from Petunia and slowly put it in her asshole wincing as the butt-plug stretched her recently fucked ass.

“And these” Petunia said handing Rose two pairs of clamps.

Rose put one of the pair on her sore nipples but was confused about what she was supposed to do with the other pair.

“You put those on your labia,” Petunia said exasperatedly

Rose winced as she clamped her sensitive labia and then she followed Petunia down to the basement where there was a new piece of equipment set up that looked like a bike.

“You're getting a bit chubby,” Petunia said “Get on and start peddling”.

Rose got up and uncomfortably sat on the butt plug in her ass.

She moaned as once she had started peddling Petunia put the milker on her boobs.

When Rose couldn't go on anymore with the peddling she dropped to the floor still butt-plugged and still being milked.

“That's pathetic,” Petunia said “We are going to need to exercise you more your stamina is horrible,” She said.

When Rose's milking session finished Petunia took her leash and brought her over to a new treadmill that had been installed recently by Vernon.

Soon Rose found herself on the treadmill as Petunia hung an extremely heavy copper bell from her nipple clamps which was an incredible amount of weight on Rose’s nipples.

Petunia turned on the treadmill and made Rose run with the heavy bell on her nipples. She then decided to strap together Rose's ankles so she had to hop, stretching and hurting her nipples a ton.

Petunia enjoyed the sound of the bell on Rose clanging as she ran fast during the training session and she was also happy to notice how swollen Rose's nipples where at the end of the session.

Petunia put a blindfold on Rose and brought her over to a new milking table that had been recently installed and because of its shape, Rose would not be able to lift herself up, which meant she couldn't pull her udders out of the milking hole. It was also very high giving a lot of room for equipment.

After getting Rose settled in the milking bed Petunia left her in there and went upstairs to go to bed herself.

Early the next morning Rose woke up to feeling the pressure of her engorged boobs.

She hoped that one of the Dursleys would come down to the basement soon to milk her.

Rose had no clue of how long she had been a cow already as she had lost all track and sense of time.

She felt a dildo entering her pussy which made her wet instantly.

She tried to hear where one of the Dursleys where but unknown to her Petunia had left the dildo there the previous night having set it to go off at a predetermined time so that Rose could be nice and horny for when the Dursleys came downstairs.

Rose was frustrated that the dildo was not going that fast as that meant she couldn't cum all she could do was feel incredibly horny.

She hated when they teased her.

After a long wait, she could hear one of the Dursleys come downstairs.

She was startled when without warning, the fucking machine was turned to a very fast speed penetrating deep inside her.

Soon Rose was dripping with pleasure and she couldn't help herself from letting out a little ‘moo’. Then the milker was turned on and Rose was being fucked and sucked at the same time

She quickly got lost in orgasm bliss as she couldn’t see, she couldn’t talk and all she could do was submit to the machines. She easily reached her first orgasm.

After what seemed like a long time all of her milk was drained and the machine was turned off but her nipples had quadrupled in size and were now stuck inside the cups.

With considerable effort, the Dursley with her managed to get the cups off her sensitive nipples. Then, the fucking machine was turned up to the highest speed it could go and Rose almost exploded and she climaxed, shivering and struggling against her restraints. She was exhausted!

This was her life now. Getting milked and fucked every day.

And she loved that.

It was so easy being a Hucow she didn't have to worry about anything and she barely had to do any thinking anymore.

(Responding to some comments)

(Reardon-The Dursleys won't be getting Rose a nipple piercing since they don't want it to interfere with her milk production. And the only way I could think of incorporating electricity was with a shock collar but I don't see a need for one of those since I don't intend for Rose to be a rebel)

(Axio-Any ideas of how Rose can be further dehumanized are appreciated. I'm not going to increase her breasts sizes since they are already G Cups and she produces 2 gallons of milk a day. I feel that any bigger for her breast size would become too ridiculous for me)

(Hentai-lover96-I think I will include Gabrielle into the story along with Fleur but not Appoline since she is a bit too old for me)

(Thanks for commenting everyone and any suggestions for what you want to see next are much appreciated the more graphic and detailed the better)
