Speed bag Mistress

Chapter 1 The new slave

It was her ultimate expression of the femdom life. The strong muscular
female boxer and male slave , exposing his manhood sack, to be repeatedly
bounced and punched  at will by the female.
She loved taking   videos of her ripped muscles, the  sweat coming off
her body as she pounded the men's balls. But Helmut was no match for her.
He tried a reverse and she scooped underneath and forcefully grabbed his
balls  in a pincher grip. Then she sucked on his over sized cock, over
and over while repeatedly crushing his testacies.Her muscles bulged with
effort as she finished with her third slave today.  After the alternating
pain pleasure he came in an explosion of cum and screamed gibberish
frothing at the mouth.. Are we done today Helmut , giving him an extra
squeeze.... He screamed yes and fell unconscious. she stopped her video
taping for the day, she realized  a prize was waiting to be opened. At
long  last ...... a  slave that meets my criteria she  exclaimed!  She
always thought men's balls
were too small. She wanted a real speed bag to hit to challenge.All her
slaves had bigger than usual balls. big cocks too!  In the cage was a
muscular man
with huge basketball  like testicles. She had recently purchased  him
from a southern woman's stock of genetically enhanced slaves. She had
ordered his balls to be at least 12 to 15 inches across.  And he was to
be conditioned to be able to take repeated
punches in his balls. They first started with
hanging weights off his huge globes until he could stand 50 pounds. Then
the slave was repeatedly struck in the nards until the onslaught was
tolerable to the slave.
After she locked him into the platform device  exposing just his balls
below,  She began punching his exposed testis like a speed bag. His balls
were firm and rebounded like a speed bag. The slave moaned and yelped
only  when she hit with her hardest punches, as well as getting a
substantial hard on but not Cumming. After a while the mistress realized
that he needed more power. She tried brass knuckles , they did help .
Often getting very  close.  But he needed more!
   Often he would moan loudly to her like he wanted hit harder. to
encourage her. The answer came to her in a flash as she worked out at a
local gym. A muscular patron was sparing in the ring. And he suddenly
lunged and knocked out the man he as sparring.  One punch that's all it
took baby, he boasted. She sidled up to him after wards and offered him a
deal.
The next day as she was chaining the slave up to  the speed bag device
and there was a knock at the door. She said I'll get rid of whoever that
is, and then we'll have some fun she said as she winked at the
overdeveloped slave.
She came back quietly with the local boxer. without the chained one
knowing it , the platform below was out of the slaves view, so it would
be no problem getting the  substitute in position.
At first she motion to the boxer to take it  easy. After a few light
thuds, the slave started exhorting her to hit harder. The madam motioned
the fighter to hit with more power.  With the first staccato of multi
power shots the slave screamed and
started masturbating wildly  moaning in gibberish. His well muscled hands
were abler. Using both hands, a polished his pole outrageous proportions
His breathing came in gasps , which meant he was close. To which the
woman motioned for the boxer to go full tilt. With the well muscled mans
first power right punch , the slave  started shaking, his eyes rolled up
in his head and it was then she started the Venus 2000 connected  to his
cock. It hummed to life and rhythmically sucked on his big overdeveloped
cock. Suddenly  in wails of increasing  tempo, ahhh, ahhhhhh,AAAAAHHHHHHH
shooting cum like a pressure hose out of his long swollen cock into the
plastic see through hose of the machine. It was as if it he was being
milked by a milking machine..
She left it on for an hour to make sure his bountiful nuts were drained.
      Afterwards she thought about many things. How she liked to think
she was helping the men who entered her  home a d how she could rectify a
solid home base for the slaves to worship her every nook an cranny on her
body. sure they get chained to the wall at night  while I fuck
every big balled stud I can drag into my bed. But that's the way it
should be the haves and the have knots. I mean while they get on their
knees to go down on my pussy why not scrub the floor with their tongues.
I do all the work day in  and day out I chain slaves, make movies of them
getting the shit kicked out them while I make money selling those movies
to the porn crazy masses. I get so tired of letting these slaves
eat my pussy and acting like I like to see them cum!  They are lucky I
feed them  the dog food that they deserve!
  Afterward the slave asked her, How did you....?  She flexed her bicep
and said " One punch baby, that's all it took!"
