My jaw dropped and it took more control than I knew seeing her with my dog’s head almost sniffing her cunt.

Amazed, I asked her casually how we could go about it.

Elaine suggested that she wanted to see a Captain’s initial sexual excitement; to see his sexual organ activated.

Suddenly it came to me that she was winding me up and I grinned, “ Aha, your joking me right?”

“Oh I’m sorry if I’ve offended you Joey, I’ve expected too much.”

“No Elaine! No offence … really. I just wanted to know you were sincere.”!

“Oh yes Joey … I’m sincere … I respect you, I do really.”

I looked into her and realised she saw me as a trusted brother; so I responded,

“Well; I think your intelligent; advanced for your age; I can also see Captain has taken a shine to you Elaine. I think he would be pleased to help you advance your studies.”

“Oh Joey! Your just wonderful – I’m so lucky to have met you!”

“There is an old saying Elaine; Strike while the iron’s hot.”

“How do you mean Joey?”

Look, we’ll all go somewhere now; simply follow me OK?” I said getting up from the bench.

“OK?” she said.

Chapter Two

We walked towards the park’s toilet facility; the dog at my heel and Elaine following.

Then I casually entered the baby-changing facility; holding the door ajar for Captain and Elaine to enter; then locked the door.

The baby-changing platform would be ideal for raising our subject to eye-level; allowing Elaine to observe the biological stages of a dog’s erection process; and maybe more besides.

“OK Elaine, lets see if we can get some proper research material for you here.”

“Oh this is such a rare opportunity to advance my biology studies Joey.” she enthused.

I thought – and for me honey bun, and for me.

I lifted Captain; stood him on the changing platform and held him steady,

“Now Elaine, if you set about stroking round his genital sheath area, it may activate an erection; but you need to keep your eye on it.”

With the realisation of her involvement she was surprised and hesitant. “Oh, I see; Right OK.”

Swallowing her nerves, she slowly began fondling between his hind-quarters but felt she was in unnatural … perhaps taboo territory … yet

“Take hold of his sheath and softly work it back and forth.”

“Oh, … like this Joey?” she whispered guiltily.

Her nipples had hardened and the dog was picking-up her sexual odour; chemistry was at work.

I egged Elaine on,

“Yes that’s it; see his red tip poking out now – it’s beginning to work for him.”

Captain had began panting pleasurably.

“Oh, how marvellous! He likes it doesn’t he! I do too!” she thrilled softly.

“Now Elaine, do you see his testicles at the back?”

“Yes! Their quite a size aren’t they!”

“Well that’s what you need in a good stud dog; include that in your research write-up Elaine.”

“Oh I will – this is all good research!”

Captain was panting hard now.

“Oh my god! Look at the size of his penis now Joey; I cant believe it!”

“Yea; the poor bitch I mate him one day will have to take all of that Elaine.”

Her knees squeezed together and beads of sweat broke out on her forehead. “Lucky Bitch!” she moaned as her hand manipulations became more elaborate.

She wasn’t alone in her excitement; I was breathless also and my cock was thumping.

“Right; keep working on his shaft, he’ll be ejaculating at any moment; do you want to taste some?”

“Oh can I!”

“It’s a once in a lifetime field-study experience for you Elaine!” I urged.

That sweet sixteen year old with her fair plaited hair and kissable lips looked at me with gratitude and whispered tenderly, “Thank you so much Joey, I’ll make it up to you somehow.”

It will remain one of the regrets of my life that I was unable to video the sensual performance of this brave, adventurous girl.

It would have captured her amazement at his red tip expanding into an astonishing shaft; her failure to conceal her own sexual excitement; and her enthusiasm an eagerness to have his jizz in her mouth; in the pursuit of knowledge.

With her mouth now fully occupied, her head bobbed along the cock’s full length.

She was oblivious to me now; in a fantasy world of discovery and understanding.

My own cock had been busting until I unzipped and sprang it free.

As Elaine choked on Captains cum, my load shot over the rear of her naked thighs; mingling with her own love-juice.

Suddenly Elaine shuddered in climax; her plaintive wail echoed around the chamber with an erotic beauty; seeming to demand a place in a Mills & Boon romantic novel.

Chapter Three

Hello!; I’m Elaine Richmond,

I was over sixteen when I first realised that I could be sexually attracted to a certain kind of dog.

A sizeable smooth-haired handsome well-bred kind of dog.

In a way, I consider myself well-bred.

Our house stands in a select part of town where my father runs his consultancy practice.

Mother runs a department at the university which I’m due to attend before long.

I’ve had the same boyfriend since I was fourteen; Gerald.

His parents have always known mine and plan for us to marry after we graduate.

We’ve progressed sexually in a respectable fashion; avoiding any penetration other than a French kiss.

Gerald is gentlemanly; but I get sexually frustrated.

At college I get a lot of attention from guys and a lot of propositions.

Some of the propositions I’m tempted to take up; yet dare not.

Instead I lay in bed masturbating over them.

Recently I managed to get a small vibrator off the internet.

But I yearn for a real cock.

Upon discovering there was a bus, that went out of town to the big country park, a vision of some freedom beckoned.

It offered a simple form of escape however short-lived, from the pressures of being a teenager at home.

I announced I was taking up jogging at the park as a pastime; much to my parent’s approval.

****

It’s odd but stepping from that bus at the country-park and setting-off in my sport-togs I felt sort of invisible.

I wasn’t that college-chick anymore. I’d became something else, with a sense of isolation and anonymity.

Then the steady rhythm of jogging; a kind of spiritual cleansing from the clutter of home-life.

At the end of that first jog while I relaxed at the park-centre café, I knew I had found another side to my life; a fresh mentality which was stimulating.

****

It was on my second trip to the park, that a new sensuality was triggered within me; by a handsome dog.

He stood proudly watching me as I jogged towards him and it struck me how sexy he looked.

He was in his prime and clearly masculine; packing a prominent cock between his legs.

But most of all, I could sense he fancied me.

My snatch stirred and for once here was an admirer I wouldn’t have to spurn.

Upon reaching the dog I paused to fondle him, while chatting to the man with him…

but I felt a physical attraction for this animal.

Then sitting on the bench next to the man, I fondled the dog further feeling a growing sensuality.

I suppose it was just a few moments I shared with that man’s dog before I was jogging off along the trail;

but not before I’d agreed to join the pair of them at the cafe later after my jog.

****

I duly turn up at the café after finishing my jog and saw the man was good to his word!

They were sat outside at a picnic table!

We greeted each other; exchanging names with humour.

His name was Joey and the dog was Captain. He often called him Cap though.

Then he offered to get milk shakes if I minded Cap.

Being alone with Cap, I was able to caress him more intimately.

As my hands ran through his warm fine coat I was filled with a heady sensuality I’d never felt with Gerald.

Within a few moments his cock began to emerge from its sheath! Gerald was just about done for now.

My snatch fizzed with excitement but I abruptly ceased; so we could both cool down.
