A Challenge

I'm issuing a challenge
For those who fornicate
Complete it, without falling out,
With a cooperating mate

Staying power is important
And the hardness of his dick
Her receptive, ready pussy
Must be all lubed up and slick

The objective is to couple
Then to cycle in for five
The strokes must be from head to hilt
And to keep the game alive

Once the cock head is inserted
Game is over, when it's out,
Changing positions, without leaving
Is what this challenge is about

The game has its beginning
In the missionary style
Five strokes and then progression
To the left side for awhile.....5
     

She brings her left leg 'round his hip
To be sure he stays inside
Five times in this position
Then it's on to the next ride.....10

Rolling again, back on her back
Her legs are tight together
Her pussy pulses on each stroke
The perfect penis tether.....15

Then to the right they're turning
She puts her right foot on his hip
Her hot hole opens widely
And he lets the next five rip.....20

Using her leg for leverage
She turns him over on his back
As stated, in the rules above,
His cock never leaves her crack

She slides her breasts against his chest
So his cock goes in and out
Those five strokes were hers to count
It was her time in the bout.....25

She does the splits and up she sits
With his hard cock deeply in
Gets on her knees, it's time to please
Taking five strokes in her den.....30

She lifts up to stroke the pup
The next five is her fun
If his cock leaves her vagina
She is not the blameless one.....35

She spins 180 on his penis
Until her ass is to his face
Five more times she cycles
To continue with the race.....40

Everything is going well
The rules have not been broken
The next moves are all optional
If they choose to keep on strokin'

He tilts over on her side
So he's stroking from behind
Five times, she's almost cumming
She really hopes he doesn't mind.....45

Her heat squirts on his organ
As she's having her orgasm
The challenge could over
His tight nuts are now in spasm

While her excited body's quaking
He has her up and on her knees
His legs are in between hers
Taking five more strokes to please.....50

He shoots his load within her
His climax is oh so fine
If his cock now shrinks and shrivels
It's the ending of the line

Surprise!, he had some forethought
Before this challenge had begun
He had swallowed two viagra
When he needed only one

They are able to continue
As the cum flows from her cunt
Their transitions, new positions,
Can be anything they want

He grabs her by her moving hips
And pulls her to the edge
Standing, he drives her five more times
With his viagra hardened sledge.....55

Then lifts her so she is standing
Spreads the sweet cheeks of her ass
To allow five deeper plunges
Not yet running out of gas.....60

He lifts her up, his cock still in
Walks towards the reading chair
While walking, strokes her five more times
While her ass is in the air.....65

He sits down, she goes to town
With a quick lap dance of  five
Then sprays upon his cock again
Never feeling more alive.....70

His nuts have now recovered
And the pressure's building up
He strokes five more to find relief
There's enough fill a cup.....75

He feels tumescence ending
Takes five strokes to end the bout
His cock is quickly shrinking
On the fifth it's falling out.....80

No positions were repeated
The fucking was a lot of fun
They both have crumpled in a heap
The challenge over, said and done
