Karen attempted to cover her huge and naked breasts with her arms. She wore only a tightly bound corset and nothing else. Her pussy lips were peaking from the bottom of the restricting bodice. Her hair was long and free. For the past three hours she had been punished. Her ankles and thighs were bound. She feebly crawled around with her tits and pussy available and in sight. Our guests would arrive any moment. I thought about fucking her mouth since it was now in front of my crotch. It was amusing that she would attempt to cover her breasts.

When she was disobedient, her usual punishment was a long tit fuck and then a huge load of my cum in her face. This she did not enjoy. Maybe that was what she was expecting. I never gave her what she was expecting. I studied her wet lips and my cock was hard but the Jones would be arriving soon. They would expect Karen to be in her place. With her this bound, she would be more humiliated than ever. However, she would also not be able to serve us. I did want to please my guests so I untied her legs and feet. I then attached her fur-lined collar. She was lovely. My prize possession.

She had been willing to endure my training for my affections and her own financial compensations at the end of two years of service. There was no turning back. It was in the contract.

I have no doubts that she would have reneged if I had let her, which made her all the more treasured, and lovely.

I smacked her lovely bum and a red blush arouse on her ass cheeks.

She went to make drinks and the doorbell rang. She knew better than to protest and answered the door with shame and tears in her eyes.

The Jones answered. Douglass had trained a dark and exotic girl who had many sexual talents. We certainly were competitive and enjoyed our bouts of upmanship at these gatherings. The girls, of course, dreaded these meetings.

Douglass eyed Karen lustily. Tamara had acquired some nipple piercing and they were bound together by a single chain. I could almost see the fear on Karen’s face as If it might occur to me to do the same in the spirit of competition. Tamara’s melons were a deep brown and her aureoles were wide. She also wore a collar and a chain and some long 5-inch heel boots that went to her thighs. Her pussy had been shaved so that there was one tuft of pubic hair in a triangle at the top of her mound.

As much a Karen probably dreaded her predicament, she was very jealous and knew that I enjoyed Douglass’ slave’s body immensely. I enjoyed her jealousy and played it up. Karen passed a drink to Douglass and he took it without a glance to her as we caught up on business. The women knelt at our sides, waiting our commands. My cock stirred as I studied Tamara’s berry colored lips.

Douglass nodded and I motioned for Karen. Tamara knelt in front of me submissively.

"Let’s see if she has learned to suck properly", Douglass taunted.

Karen looked at me, her face pleading. When she saw there was no mercy there, she pressed his cock to her lips. She tucked her head and sucked his cock to the balls.

Tamara unzipped my trousers with her teeth and was rapidly flicking her tongue over my hardened flesh. She was well trained. Karen knew better than humiliate me and she was sucking for dear life. I told the little slut that I would tie her legs and let her drag around without help for a week if she didn’t please Douglass orally.

I don’t know if Tamara had a similar command but the girls were outdoing themselves. Tamara’s eyes rolled in the back of her head with the intense suction she was applying to my cockhead. Karen was deep throating Douglass with newfound skill. He nodded towards me that he was impressed and I looked nonplussed.

Since it had become a contest, the girls were trying to see who could get us off faster. They slurped and sucked and licked, occasionally looking over to see how the other was doing. A couple more quick suctions of Tamara’s lovely mouth and her chained tits bouncing as she bobbed and I came in her face, maybe moments before Karen got a faceful of cum from Douglass.

We laughed and compared girls in front of them, finally allowing each other to lick the cum from the other.

Karen still had a year and two months of training. When I was finished with her she would not want to leave me. I was sure of it.

It was finals week and here I was a freshman in collage spending every
damn minute I had at the campus library. I hated Biology and my grades
showed it. I should have been out partying with the rest of the dorm,
getting drunk, getting laid by some senior physical ed major. But no, I
was behind a book at a table on the third floor staring endlessly at
research notes as all hope of me passing this class was about to catch a
bus to nowhere. There was a loud noise as some jock who tipped over a
book cart a couple tables away from me. Then I heard her voice, Ms.
Birmingham, the old librarian who's crabby old face was only out matched
by the strength of her mothball scent that filled the library.

"That will be enough of that young man! Pick up those books and exit
immediately!" She pulled down her glasses to get a better look at the
klutz who somehow managed, I am sure, to get an athletic scholarship.
She looked about the room to see who all was watching or had been
disturbed. She caught me red handed looking straight at her and I
quickly hid behind my book.

A couple hours had gone by, and the library hall had cleared out except for a few of
us desperate final crammers. I was going over the reproductive systems of mammals
when I was startled by a cold hand on my shoulder. "I find it hard to believe a freshman
like you needs to study on reproduction."

My heart skipped a beat, but without even turning around I knew it was Ms Birmingham.
My face grew a bit red as I tried to come back with some respectable answer. "Yes
Ma'am, but if I don't pass professor Acklins Biology class, I may just lose my tuition from my
parents, not to mention miss a chance at a promising future and career in medicine."

"Well you being here at this hour young man, things are not looking very
promising. The library closes in one half hour, do you think you will
have soaked up all the knowledge you need by then?" She said as I turned
around to look up at her.

"Ma'am, I hate biology, I don't think a week in here would help me."

"Well then, you do have a problem then don't you?" A smile seemed to
almost crack the skin of her soured face. "It might be that I can help
you. I know a lot about biology and reproduction. Come into my office
after I turn off all the lights and lock the doors. That is of course,
unless you have some place you have to be?"

My eyes must have grown ten times in size, for I had never seen Ms
Birmingham smile, Let alone offer to help anyone outside of her normal
librarian duties. " No Ma'am, I mean no, I don't have someplace to be."

"Very well then, I will see you in my office in about 30 minutes..." she
paused for me to introduce myself.

"Brian... Brian Fortsmith Ma'am." I almost forgot my own name, how was I
ever going to pass this class.

I got to her office a little early, as I could hear her turning off
lights and locking doors. I looked about her office, looking at pictures
one caught my eye. I walked up closer to it to get a better look. It
couldn't have been. I thought to myself. Just then I heard the door
close to the office. I looked back to see Ms Birmingham standing there
smiling at me.

"Yes, that is me with Professor Acklin. We went to school here many
years ago. That picture was taken outside the library on the front
steps."

"You and the professor dated Ma'am?" I said, most puzzled.

"Still date, although that is a secret... yes?" She said with her brows
scrawled.

"Yes Ma'am, that secret is safe with me." I smiled with a blush.

"Sit down Brian and relax your mind. I imagine it's well worn from all
the studying you have been doing." She walked around and sat in the
chair behind her desk, getting a cigarette from one of the drawers and
lighting it.

I was a bit shocked that she seemed so relaxed herself and a bit loose.
Nervous and a bit confused I asked " So how can you help me Ma'am?"

She leaned back in her chair "Push your chair back so I can see you
Brian."

"What?"

"I can't see you, well not all of you, push your chair back so I can see
you better."

Thinking it was because she wasn't wearing her glasses I did so without
a second thought.

"Much better" She smiles again while blowing her smoke up into the air.
"Now, you help me Brian, and I will help you. As you now know, I have
some influence with the professor as to the outcome of your final
score."

"Help you Ma'am? How can I help you?" I said, now totally confused and
baffled.

"Unzip your jeans and let me see your cock." she said, as she pulled
down the glassed from atop her head and put them on.

Did she just say what I think she said? "Excuse me Ms Birmingham?"

"You heard me young man. Unzip your jeans and show me that cock of
yours. I want to see you play with it and get it nice and hard for me.
Can you do that Brian?"

Ok, I am going to fail Biology if I don't unzip my pants for this old
woman. Lose my money for school and forget about becoming a doctor. What
would you have done? I was desperate, hell I was horny too. All this time at school and I
hadn't time to get laid. I unzipped my jeans and pulled out my cock.

"Nice, very nice Brian. Now stroke that cock for me. Show me how naughty
you can be." Her tongue rolled across her lips as her eyes locked on to
my dick.

I stroked my cock up and down slowly, pulling up hard on the rim of the
head. My cock was growing harder with each stroke. I looked up at her to
see her eyes still staring at my throbbing shaft and one of her hands
now hidden beneath the desk between her legs. I looked back down to see
pre-cum glistening out of the whole in my head.

"Stop!" she screamed "Don't touch it... don't you cum you little shit!"
The old gal scared the piss out of me, but I didn't cum.

"Yes Ma'am"

She got up from her chair and walked around the desk, kneeled in front
of me and threw her glasses back behind her on the desk. She pulled off
my jeans the rest of the way and tossed them to the side. Her cold hands cupped my
balls as her tongue lapped and curled around my shaft.

"Such young cock, so hard, so smooth" she said between moans.
I reached down to touch her and she pinched my left nut. "Do not touch
me, just sit there and be a good boy. And for gods sake, do not cum in
my mouth." She said as her mouth enveloped the length of me. Her right
hand holding my cock steady, her left kneading my sack, she sucked,
licked and nibbled my cock like some sort of dish... served HOT! I was
about to blow my wad when she suddenly stopped and stood. She reached
behind her and undid her dress which dropped to the floor, her bra and
panties I had seen before... my god, they looked like my grandma's! Her
panties already had a wet moist spot on them from fingering herself
behind the desk. She pulled them down and took of her bra. Her tits were
sagging and her bush was hairy as could be, but I was so turned on
looking at this old lady that my cock throbbed even more, just craving
to be in her old hairy cunt. She straddled the chair on top of me,
crabbed my cock and guided it into her pussy. She slid down on me and I
could feel every fold of her old cunt crossing over my dick. God, her box
was wet and hot. It felt so good to be inside her.

"You are such a naughty boy Brian. Fucking an old woman, I could be your
grandma. You like fucking your grandma Brian?" She said as she bounced
up and down on my cock.

"Yes Ma'am!" I said with enthusiasm.

"Good, now make your gramma cum little boy." She got off of me and
pushed everything off her desk onto the floor and laid back on the
wooded top spreading her legs wide.

I mounted her and thrust my dick deep into her cunt. I felt her juices
on my balls as they slammed into her snatch. She grabbed one of her old sagging
tits and lifted it up "Suck on grandma's nipple, bite them."

I did as I was told, I didn't want grandma... I mean Ms Birmingham to
scold me again.

"Such a good boy you are. That's it fuck me hard, make grandma cum."
With that she grabbed my hair and her legs wrapped around me holding me
in, pulling me in as she screamed in pleasure. "Oh yes... you are a good
boy. Now cum inside your grandma, fill her up with your naughty thick
hot load." My cock spilled all of my first semester jizz in her old
cunt. Filling it up with that hot white pearly cream, so much so it
oozed out and into her thick and hairy bush.

"That's my boy... good boy" she petted my head and smiled. "I think you
will do very well... on the Biology final Brian." She reached back into
her desk drawer and lit another cigarette as I dressed myself.
As I was walking out the door I heard her say. "If you need help with
any other classes, you know where to find me."

I turned around and told her. "I think I have reproduction down pat now.
But I do have this oral exam next week."

She blew the smoke out from her mouth. "See you next week then, you
little shit." and she smiled as I shut the door.
