As they say in the movies, this is “Based on a true story”.

I (M42) was a second line manager for a major computer company. A marketing assistant - let’s call her ‘Joanne’ - was about 15 years my junior and working under me.

Joanne was sexy and she knew it. Slim, about 5’8” with firm C-cup breasts, she often wore a short pin-stripe skirt that showed off her slim, tanned and toned legs. She had blazing red hair that fell to almost her waist. She normally wore a sheer white blouse that always felt a size too small for her such that her luscious breasts were always trying to pop the top button. For business shows she would complete the outfit with ‘fuck-me’ black shoes with kitten heels. It was never a surprise to find that a flock of middle-aged men would often be intently standing next to her as she demonstrated our latest software. I often smiled as I saw their eyes go from the screen to down Joanne’s blouse and back again. I could often see their erections stiffen within their business suit pants!

We had often flirted outrageously as she clearly fancied me, either for my looks or my power or both. But other than a drunken snog and a grope in a quiet corner during a Christmas party, it had never gone further than that.

Roll forwards to a sales meeting held in Orlando. As a well-travelled Brit, I had long since stopped bringing my wife along on such trips, but this was a novelty for some of the junior staff. On this occasion, Joanne had brought her boyfriend - let’s call him ‘Mike’ - along for the weekend before the sales meeting. By chance, Joanne and Mike were in the room next to mine at the Hilton.

The bete noir of flying to the States is jet-lag and this was no exception. I was awake at 5 am and however hard I tried I couldn’t get to sleep again.

It was then I heard the first moan from the other side of the wall. My mind immediately filled in the blanks. Joanne, naked on the bed with her luscious red hair splayed across the pillow. Mike with his head between her legs, a little well-trimmed triangle of red pubic hair pointing to her pleasure centre. As Mike worked her clit with his tongue Joanne continued to moan loudly with the occasional gasp as I imagined him darting his tongue into her soaking wet slit.

By this time, by shorts were down and I had my cock in my hand. It was already hard, 6 and a half inches and as straight as a poker.

Her moans were then replaced by a different noise. BANG. it was the noise of their headboard banging against the wall. Mike had clearly replaced his tongue with his cock and was driving with long slow thrusts into Joanne’s now dripping cunt. Joanne started to vocalise:

“Oh yes Mike”

(BANG)

“Fuck my pussy with your big cock”

(BANG)

“There… right there…”

(BANG)

“Fuck, yes”

(BANG)

While this was going on, I was stroking my cock in time to Mike’s thrusts and getting closer and closer to orgasm imagining the scene next door.

“Faster Mike”

(BANG, BANG)

“No, faster Mike - Fuck me like a fuck doll” (BANG, BANG, BANG… my hand on my cock was now a blur)

“yes…. Yes… Oh Yes Mike… FUCK MY CUNT….. “

“YES!!”

Then Joanne orgasmed with a cry that was more animalistic than human. The noise effortlessly made me reach my peak and I shot rope after rope of cum over my upper chest, face and the bed head behind me.

The banging continued at a fast pace for another 30 seconds until I heard a grunt and knew that Mike had shot his load deep into Joanne’s pussy.

90 minutes later and I left the room for breakfast just as Joanne came out of her room in business attire and dressed to kill.

“Good Morning” she said cheerfully.

“Well, I know YOU had a good morning!”

Joanne blushed a shade of red that matched her hair and started stammering

“Oh, my G-g-god, I’m s-s-so sorry”.

I came close and whispered in her ear “Don’t worry…” I said, resting my hand on her right ass cheek and giving it a little squeeze. “It was the sexiest thing I’ve heard in years… and very, um, effective”.

Joanne didn’t withdraw from my hand on her ass and a look of hot intrigue crossed her face. She smiled coyly knowing that she’d been able to make two men cum that morning.

Mike was flying home that day and there were another five night of the conference still to go.
