We were working late on a presentation for a client. It was about 10:30 pm and
everybody bar the security guard downstairs and Kate and myself was long gone
from work.

Kate was my boss, and boy was she a bitch. She worked hard and expected
everybody else to do so or there would be trouble. Generally she gave every one
a hard time - in particular myself. The other workers really hated her, they
called her the "ice maiden" and claimed she had balls of steel.

Since Kate worked such long hours, everyone wondered about her sex life - or
rather what they thought was a total lack of it! My co-workers wondered about
her sex life because, despite the fact she was a total bitch to everyone, she
was a foxy chick and I mean really foxy. Kate was about 30, slim, with long
blonde hair and legs to die for.

Of course Kate knew this herself, which was why she was so successful. She would
go to clients dressed in short skirts, and low cut blouses and shamelessly
flaunt her sexuality until she made the sale. And boy did she make sales! She
was the top sales woman in our division that was why they made her our boss.

Anyway I guess you could say I was hired as Kate's gimp to do exactly what she
said, when she said it. My co-workers all thought I had it bad - and I did - she
used to treat me like dirt.

However what my co-workers didn't know was that there was a "side benefit" to my
position. Kate and me had been having, I guess what some people might term a
"relationship". What it really was, was that I was her sex toy - not that I
minded!

Anyway we had just finished off the presentation. Kate said

"I've been busting your ass all night, if you've been a good boy, it's time for
your treat."

"Have you been a good boy?"

I had been a good boy. I had complied with the order. I had been wearing a pair
of her Louis Vutton Silk knickers all day. She thought it would be kinky to have
me walk around the office all day wearing her underwear, with her knowing this.

And you know what? I had found it pretty kinky too. For most of the day, I had
to fight to keep down an erection. Hell I'd have jacked off during lunch in the
toilets - only Kate had expressly forbid this.

Kate ordered me to undo my belt and unzip my trousers in order to see me in her
knickers.

"Mmm..... sexy" she said as I complied with her command and saw that my member
was at full attention, already fighting to escape the confines of her tight
knickers.

"Now for your treat." Kate said

" I want you to turn around, and place both your hands on my desk, palms down"

Again I obeyed her order, which involved me bending forward, exposing my ass,
only covered by silk panties, while Kate stood behind me.

"Now, DON'T TURN AROUND..... no matter what", she commanded.

"It's time for your treat. It's something that both you and I will get off on"

At this stage, I knew it would be something special, whatever it was. My penis
throbbed dully with anticipation. It felt like a monstrous erection, already I
was straining for release.

"Take a look at this" Kate whispered in my ear, as over my shoulder she placed a
jar of Vaseline on the desk in front of me.

"I've heard that the male G-spot is in the anal passage. Shall we find out if
that's true?"

Then Kate leaned over me again and placed, what I guessed to be a 12" strap on
dildo on to the desk.

Could she mean it?? It was so kinky, that I felt my erection jump a further
notch.

"I've bet you've told your co-workers that I've fucked you over haven't you?"
Kate challenged.

"uh-" I replied

"Wouldn't it be fun if I really did fuck you? Be a good boy and I'll let you
fuck my ass in exchange" Kate whispered seductively into my ear

And you know what? She meant it - Kate never broke her word. That was one of the
reasons why she was the top saleswoman.

"Go for it" I stammered. I mean I wanted her ass, and she wouldn't take no for
an answer from me anyway.

Kate reached around, and removed the vaseline and the dildo from the desk.

"Don't turn around" she warned.

By this stage my dick and balls were pumped like they'd never been, I felt like
I would explode if I had to wait much longer.

I felt a hand pulling the silky knickers covering my ass to one side. Then
slowly, a solitary finger began pushing and probing my anal passage. Kate must
have used plenty of vaseline because the passage was surprisingly easy.

Then another finger joined the exploration and another until, eventually her
whole hand up to the wrist was rammed up my ass.

Then Kate withdrew her hand, and there was a pause and a rustle as she dropped
her short skirt and strapped on the dildo.

"Here I come - ready or not" she taunted.

I had expected she would go hard, but she smashed the dildo in with an
incredible thrust of her hips.

"Ohhhhhh.......yeah.......harder" I cried out in extremes of pleasure with some
pain.

My god, I didn't know she was that strong and she attacked my ass with a
ferocity I didn't know could be possible.

How long did this go on? I could tell you but it wasn't that long, there was no
way I could last in my excited state. What I do know is that my orgasm was
monstrous, it his me so long and hard that I bucked at the knees and lost
consciousness for a moment of time.

When I came to Kate was smirking at me.

"Oh what a mess the little boy has made"

And she was right.

I must have had the orgasm of the century. There looked like about half a pint
of my cum splattered on her mahogany desk. I also had spun around some how,
because there was another half a pint of cum splattered on Kate's left thigh,
knee and calf, the sticky whiteness contrasted against the dark silk of her
stockings and garter (she had taken off her skirt to fit the dildo on).

"Ohh... you naught boy. I think you'll have to clean up that mess. Why don't you
get on your knees and lick it up?" Kate scolding like a school teacher with a
bad pupil

"Lick it ALL up" she repeated.

Well I guess you have to obey the boss! I started over by her desk and slowly
began to slurp up my salty, sticky seed. I drank my cum as I moved to clean the
desk entirely - it wouldn't be a good idea to leave something for the cleaners
to notice tomorrow morning right?

Then - and this was my favourite, I had to lick my cum off her gorgeous legs. As
I said at the start of this story I'm a leg man and with Kate standing in front
of me, in high heels and suspenders, looking a million dollars, I could feel my
shrunken dick start to twitch with excitement. I started with the toe of the
shoe where a big salty drop had to be hovered up. I slowly licked up her calf,
the taste of my salty seed and her silk stockings was intoxicating, I could feel
my member return to half mast. I moved up to her knee and then her succulent
thigh, slurping away. I noticed that the crotch of her knickers was wet with her
own excitement. By now I had returned to full erection state - something I
wouldn't have believed possible before the night.

"You've been a good boy" Kate murmured

"Now suck my tits and your treat will be here soon" she commanded.

I unbuttoned her white work blouse and slowly pushed up the cups of her silk
bra, revealing fully erect nipples as I had suspected. I licked and sucked on
those nipples for all I was worth, while I let my hands fondle her steadily
wetting crotch. My fingers massaged her clit through the silk material of her
knickers.

Kate let out a low moan. I knew she had to be close to getting off herself.

"And now for your treat - my ass" Kate said as she handed me the vaseline.

I turned her around and pushed her over the desk where I had lain not so long
ago.

While I licked her ass she reached into the desk drawer and took out a vibrator.
I continued licking her ass as she switched on the vibrator and plunged it deep
into her crack.

"FUCK ME NOW" Kate screamed and I knew she was very close.

I slapped on some vaseline onto my by now massive erection and quickly rammed it
into Kate's quivering asshole.

She grunted and I knew that I too was close to the edge of another gigantic
orgasm. I slammed into her as hard as I could manage, while she some how
continued to manipulate the vibrator against her clit and vagina.

The suddenly Kate started screaming.

"FUCK M E, FUCK ME HARDER, OH YES"

Then I was screaming too.

"I'M COMING OH GOD YES YOUR ASS FUCK YES"

Kate convulsed as a massive orgasm penetrated her body, I finally capitulated
myself and let loose a volcanic eruption of cum up her ass. Kate screamed with
pleasure, I was still cumming and cumming as I continued to pound her ass. Kate
and myself kept churning away at each other for the next few minutes as
gradually our orgasms passed.

And then we were done.

Kate said

"See you tomorrow - don't be late for that presentation".
