Summary: Susan discovers her new sense of self as she asserts her
self as a slut and takes pleasure in punishing a male class mate.

**********************************

I was still buzzing when I got to the gymnasium. In part it was a
hangover from my meeting in the Headmistress's office and the
multiple orgasms had on the floor of the teachers bathroom. The
plug in my ass was now becoming a cause for pleasure in its own
right. Every step I took shifted the intruder and brought up
desires that a day ago would have caused me to shiver in disgust.
 My class was standing in two lines awaiting the start of the
lesson. I added myself to the group and saw Jenny in the front
row. She turned and gave me a surprised look. I winked and she
turned back and faced the gym floor.

A voice echoed across the room, "For the remainder of the
afternoon we will be practicing what you have learnt over the
last week." The teacher's voice moved around the group until I
caught sight of her in my left eye. She was older than all the
other teachers with streaks of great through her ebony hair. My
guess was late forties but with her toned physique and
magnificent breasts she was still stunning. A whistle connected
to a red lanyard hung around her neck and in between her breasts.
Though not the largest I had see that day they were firm and
round. Based on her figure they had to be fake. Not an ounce of
fat was to be seen, but at the same time  she still appeared
elegant and feminine. "Front row, roll out the mats" she paused,
"Go!". On that word the front row, a mix of boys and girls ran
over to the far corner of the gym and began rolling out a series
of long vinyl covered foam mats. "Rear row, ten star jumps, Go!".
As we started jumping I looked down the row at the boy next to
me. He was slightly taller and although my age had the beginnings
of a mans physique with nice pecs and flat abs. The other part of
him that caught my attention was his cock. Locked in a plastic
cage with only his balls exposed to the air it was bouncing up
and down. This bouncing was clearly having an effect. His cock
swelled inside the device and the tip tried to force its way out
of a narrow slit in the front. This pressure dragged the rest of
the device forward pulling his sack through the retaining collar.
His sack went tight as his balls were squeezed against the hard
plastic. The discomfort was evident on his face but his cock
strained for release none the less. He looked at me and I looked
at him. I smiled, looked down at his crotch and then licked my
upper lip as we finished our jumps.

Before I could speak the teacher called out again, "Two rows on
the far side of the mats, Go!" We ran over and I lined up behind
the boy with the straining cock. His ass was toned and his
shoulders had the form of a swimmer or a rower. While the rest of
the class formed up I caught myself thinking about the object to
my front. I didn't know his name but I knew enough. He has
handsome, fit and randy as hell. He looked over his shoulder and
caught a glance of my ravenous eyes. He spread his feet ever so
slightly and pointed his feet slightly closer to straight. All
this had the effect of tightening his butt and exposing the a
portion of the base of his school plug.

"Jenny" the teacher called out, "what did we learn this week in
class?". Having only started class today I was thankful that she
asked my room mate not me. "Measurement of human physical
performance Ms Smith" Jenny called out. "Good, lets see if you
can do better. Name a method of comparing human aerobic
performance across a group." Jenny paused and thought, "We could
measure how long people can hold their breath?" She was less
confident than before and her words hung in the air. "Good
answer" replied Ms Smith. "Today class, we will conduct a
comparative test, Who would like to be part of the
demonstration?" The class was silent and no one made a move.
Despite the sexual antics it seemed that none were keen to
volunteer. Having lost my sense of shame at the bladders of her
colleagues I caught Ms Smiths attention by raising my right hand.
"I would ma'am" I called out. "Ah, the new Jenny that I've been
hearing about," she quipped. "I'm sad to say that I was busy over
lunch and was unable to," she pondered with a wry grin "shall we
say, spray my piss into your thirsty slut mouth." Jenny's eyes
darted to mine with a look of shock.

I too was surprised with my new teacher. Not because of the
revelation that I had been transformed to a piss slut, but the
phrasing of her quip. It was almost like she expected me to be
frightened of hearing the events of the lunch break recounted in
public. My competitive streak came running to the fore, "I'd love
to drink your sweet nectar anytime Ma'am." In part it was sarcasm
aimed at showing I was no pushover, but I wanted it. The
opportunity to go further, but not just for myself, but to be
seen by others seeking it out. To be looked at as the girl who
would do anything anywhere with anyone or anything. My heart
quickened as I digested the effect of my words.

"Out front on your knees, Go!." There was no need for Ms Smith to
say my name, every one who could hear knew who she was talking
to. I pushed past the boy to my front and stood in front of Ms
Smith. Through the corner of my eye I could see a look of
amazement on Jenny's face. I placed my hands behind my back and
with each hand held the other elbow. I slowly knelt on the mat,
my mouth open looking up into Ms Smith’s eyes. She stepped
forward and took her whistle off her neck. She placed the lanyard
around my neck and placed her cunt into my face. I felt the
lanyard pull my head forward as she dragged it between her legs.
My face was mashed into her mound as she began her stream. She
hadn't been to the toilet in quite a while. A salty spray gushed
into my waiting mouth. I sealed my lips against her pussy and
began swallowing as fast as I could. A single droop of wasted
fluid would be seen as failure after my brash statement. I gulped
and choked as some of the torrent sprayed up the back of my nose
passage. I felt her flood stop as the piss that had entered my
nose from my throat ran down my cheek. The lanyard around my neck
fell slack and I quickly tilted my head to the side. Keeping my
hands locked to my rear, I guided the precious drops towards my
waiting tongue. Once close enough I lapped it up, looked up at Ms
Smith and again opened my mouth ready for more. I could see her
clit throbbing out of its hood and her nipples bursting from her
chest. The cord around my neck went tight again, this time though
as my lips locked on to her mound she reached down and held my
nose shut. I waited, ready for more of her salty nectar, but none
was forthcoming.  She tilted her hips forward and I understood
what was required. My tongue darted forth and lapped at her cunt
as my top lip hummed against her clit. My heart began to race as
my lungs burned for release. I knew that Ms Smiths orgasm was the
key. She began to quiver as the pleasure rose in her belly. I
probed deeper and deeper, all the while keeping my hands firmly
at my back. She convulsed as her orgasm reached its peak. I was
sure that my face embedded in her crotch was the only thing
preventing her collapse as she released my nose and steadied
herself with an hand on my on my head. The lanyard went slack
again as she guided my face from her now dripping minge.

"Well done," she said "lets carry on with the demonstration shall
we. Lie on your back with your legs facing the rest of the
class." I did as commanded and awaited further instructions as
she removed a fluorescent plug from her ass. "To ensure we get an
accurate result of how long you can hold your breath we need to
ensure a tight seal" Ms Smith stepped over me and lowered herself
onto my face sliding her slightly gaping ass hole over my nose.
Her now engorged pussy lips sealed across my mouth and the world
went dark. I could hear her explaining what was a good time or a
bad time, signs to look for and when the tester should get off
the subjects face. "In particular you need to check some where
that is getting lots of fresh blood for any discolouration" she
explained as her fingers parted my pussy lips for all to see.
"Pinch the skin and wait for it to regain its colour" she said as
squeezed my clit. My heart raced as I felt my blood boil, Again
she squeezed my clit, but this time she didn't let go instead she
twisted and pulled my sensitive nub. The pleasure it caused was
almost overwhelming but the pain prevented me from going over the
edge. I slapped Ms Smith on the back and she realised me from her
loins. As the seal around my lips broke I wasted no time in
sucking in much needed air. Along with the cool relief I inhaled
a mass of wet juices dripping from Ms Smiths snatch. I choked.
coughed and jerked my head upwards driving my nose further into
her back hole. This caused a chuckle of laughter from my class
and my teacher. She leant forward and stood up. "That was an
excellent demonstration Susan", she remarked. "You've set a very
competitive time of one minute and eight seconds. Now back to
your spot."

Still catching my breath I returned to my spot behind the boy.
"Those in the back row will first test the person in front of
them" Ms Smith announced. The stud to my front twisted his head
slightly. Not enough to look behind himself, but enough to let me
know he was pleased with the thought of my ass smothering his
face. "Front row on the mats, Go" ordered my latest piss donor.
The boy sprang forward and lay on his back looking straight up at
my dripping puss. "Rear row move into position but don't sit down
yet, Go" I stepped forward lingering over his head  and squatted
slowly to give him a good look, his cock strained in its cage. I
held the squat just above his face and pondered out loud, "Ms
Smith played with my clit to check that I was alright, what
should I play with here…" I ran my hand down his smooth chest
towards his throbbing cock which strained harder against its cage
with every heart beat. I noticed his cock head becoming damp as
my hand got closer. "It is in the best interests of those about
to be tested to remove their testers plugs, do that now." Ms
Smith said interrupting my torment of the boy between my legs.
Without a word he reached up and began to gently pull on my plug.
It had been in all day and with all my orgasms my sphincter had
locked itself tight. Slowly but surely my partner began to loosen
the metal object from my ass. My hole stretched more and more and
my arousal built once again. My mind recalled the scenes of
Melissa's ass being worked by her shower lover and Ms Jones.
Finally it came free and a rush of cold air rushed to fill the
gaping void that was my ass. I shivered, in part from the new
sensation and in part from the final tug he gave.

"Once the tester and subject are ready you may begin, and don't
forget to count" ordered Ms Smith. Without waiting I dropped my
self on the hapless boy's face smothering him mid gasp. His nose
disappeared into my ass and my dripping lips went firm around his
mouth. I gently began to stroke the hairless base of his confined
erection whilst my other hand twisted his nipple. I could feel
his heart racing as my finger found its way to the end of the
cage. There I gently slid my fingernail into his piss slit that
was being forced out of the cage. That was too much for the boy
sucking on my juices. His hips bucked and his hands gripped my
hips holding me hard against his face as his tongue flickered
into my pussy. His nose too went deeper and went someway in
replacing the plug now resting by my foot.  As he quivered his
orgasm came and with it a load of cum spurted from his cock over
my hand and the gym matt. Ms Smith noticed the commotion it
caused and closed the distance with purpose. "How dare you do
that in my class, you're going straight to detention young man!"
She exclaimed as she took off her whistle lanyard. I recoiled in
fear as she swung the whistle towards us. The whistle struck the
boy square on his straining balls. He curled up in agony as the
the teach grasped him by the ear.

I was shocked, not least of all because I was the one who cause
his orgasm. As I lay with my legs still wide apart I gazed at Ms
Smith as she dragged my boy away by the ear. "Class dismissed"
she called out leaving us to our own devices. I looked around and
saw Jenny moving to my side. "What a disgrace she said as she
moved to hug me. I pushed her away unsure of all that surrounded
me. "We're all going to pay for that one way or another" one boy
remarked to another. I couldn't believe my ears. I turned to
Jenny, "Whats going to happen to him? It was my fault, he
couldn't help it" I asked and explained. Jenny gripped me and
looked me in the eyes. "Don't blame yourself babe, he knows
better than that" she said. "All the boys know that their not
allowed to cum in class". Still in a state of disbelief I pressed
Jenny to find out what what would happen next, "We'll all see
soon" she replied.

Everyone now started to re-plug their holes. Some required
assistance, others were fine on their own. We gathered around
awaiting the end of the period. Even I knew that the next class
was detention. We moved as a group into the courtyard to find the
boy locked in a set of stocks set up amongst what I had
previously thought of as gymnastic equipment. I now realised that
his was no sporting area, It was an open air dungeon. As the
class rooms emptied a small crowd gathered around. "What are they
going to do to him?" I asked Jenny. "You and Ms Smith are going
to be plunder him with giant strapons" she replied matter of
factly as she rubbed her hand along my cheek. I was aghast at the
thought of hurting this class mate of mine but the thought of
pillaging the boy's ass was beginning to arouse me. "What counts
as a giant strapon" I asked. "Well it depends how old you are"
Jenny explained. " You take your age, multiply by four and
subtract fifteen. Thats how many dildo inches you get." She
seemed quite serious and knowledgeable about the matter. "Now
this is where the boy will get a choice. There are different
lengths and widths available, all he has to do is pick one where
the length multiplied by the length is greater than his dildo
inches. I did the maths, he had to take 41 inched of synthetic
cock. " That's huge I exclaimed" as I realised that even if the
dildo was three inches across it would have to be over 13 inches
long.

"Its show time" Jenny remarked as Ms Smith walked up to the boy
with a long bag and placed it to the side. She looked around,
seeing me she waved me forward. As I emerged from the crowd Ms
Smith handed me a strange device. It was two reasonable large
dildo's with small grooves on the side connected to a curved bar
of plastic. There was a stepped protrusion facing away from the
dildos and a small knob beneath each. "Come on, I haven got all
day" said Ms Smith as she removed her fluorescent plug and placed
it on the grass. She slid the bar in between her legs and raised
it, a dildo entering each of her holes. I now realised what this
device was, some form of strapless dildo mount. I followed suit
removing my own plug and sliding the plugs into my gaping ass and
still tight pussy. I saw Ms Smith fiddle with the knobs between
her legs for a moment before she reached for my own. "This will
keep them in" she explained. As my teacher twisted the knobs each
of the dildos expanded in my young holes. She continued to
ratchet them open until the deice was firm locked against my
young body.

Ms Smith then handed me a bottle of lubricant and directed me to
prepare his ass. Unsure of what to do I gently removed his plug
and smeared some lube onto his waiting hole. "Like this" Ms Smith
said as she grasped the bottle from my hands. She inserted the
end into his anus and squeezed filling his rectum with slick
jelly. Ms Smith then moved around to his face, squatted and asked
him for his preferred size of dildo. " The one with the big bumps
and the long red one please ma'am" he replied. Ms Smith retrieved
the dildos from the bag and gave me the choice, A red one almost
a foot and a half long over two inches across or one just over a
foot long with a series of bulges that increased in size towards
the base. The expandable dildos in my two holes were having an
effect other than the security of my harness. I realised that he
was going to get both dildos any way. If I took the thick one I
could be gentle to him, I supposed as I reached forward and
grasped the toy. But deep down I knew that it wouldn't be that
way. I could feel the lust building as Ms Smith affixed her long
toy to her harness and guided it deep into his colon. As Ms Smith
slowly reached her full depth I saw and amazing sight. I could
see the toy bulging in his belly. By the long line of cum seeping
from his cock, this punishment appeared as effective as my own
earlier in the day. He was writhing in pleasure as the rubber
snaked its way through his insides, moaning each time The older
woman thrust into his boy ass. She too was enjoying herself as
the dildos moved around inside her. Her pace quickened and with
deep thrusts she assaulted his shitter. She gasped and shivered
as her loins convulsed sending shockwaves throughout her body.

Ms Smith slipped the dildo from the young man's ass, turned to me
and said “Your turn Susan." I stepped up with the head resting
against his gaping hole. As I pushed forward the first of the
bulges slipped into his ass with ease. Further still the second
bulge met with some resistance. He moaned as I began to softly
thrust into him. in a few moments the dildo was half in.The third
bulge however was no such slouch. I reached forward and held his
hips as mine pushed forward. with each thrust he moaned in
pleasure as his sphincter was stretched wider and wider. My pussy
was tingling and there was a fire building inside me. I began to
move harder and faster assaulting his ass. The third knob popped
through only to be dragged back out a half stroke later. In and
out it went, our skin drenched with sweat. His caused by the
pleasure he felt as the toy working in and out smacking on is
prostate. My sweat was in part due to the pleasure in my own
holes as the dildo's held on tight. The physical act too was
causing me to pant as by hips flashed back and forth. I was
loving this. The feeling of power over the young stud before me,
the visible distress of his ass was almost more than I could
take. There was only one thing else to do. The fourth bulge,
unlike the others had no narrower back side, simply retaining its
3 inch girth right to the base. As my orgasm approached all
thoughts of mercy dissolved. His ass was mine and I would make
sure that he would never forget this ravaging. Again and again I
thrust forward. Harder and harder. His hole continued to dilate
with every thrust. A wave of pleasure washed over me and I lost
all concern for his comfort or safety. I rammed the dildo in with
all my strength gripping his tight hips as his ass succumbed to
this final intrusion. He cried out and convulsed as my three inch
diameter tool remained buried in his ass.

I withdrew the toy from his now plundered hole as it gaped back
at the crowd. A small round of applause erupted. I looked around
and made a small bow of thanks. The crowd began to disperse and I
saw Jenny approach as I removed the mount and returned it to Ms
Smiths bag. "That was incredible" my rommie exclaimed as she
hugged me close and kissed me. "How have you become such an
animal? I heard about your punishment and you shocked everyone in
the gym." I reassured her that I was still the same girl, but I
was just caught up in the moment. I knew this was a lie, and I
think she did too. As I looked back at the boy who's name I still
didn't know his ass still gaped as a trophy to my new desires.
