Fountain of Youth

All the following characters are over the age of eighteen.

.............................

Undergraduate life wasn't as much fun as I'd hoped. Being a broke working class student in a decidedly middle class university was becoming a drag. I had no well-off solicitor or doctor daddy to fund the party lifestyle I aspired to. My poor farmer family could just about pay my fees and rent and have enough left over for some simple food, so my social life and my prospects with the "jolly-hockeystick" young ladies in my first year medicine class were not looking good.

So the short note in the bottom of the weekly faculty newsletter caught my attention.

"Wanted: Healthy young men for clinical trials. Remuneration offered."

So I banged off an email and an appointment was soon made for an interview and a physical. The tests were your standard blood, cardio, visual aural, etc plus the full gamut of std checks. I had to wank into a cup for a semen quality assessment and there were several questions about my recent sexual history and even my masturbatory habits. The first question was easily answered - "none," while the second question needed more elaborate detail. Such was the nature of my lonely erotic life.

The following week was the interview with the faculty head of pharmacological research, Prof. James Murphy and the clinical director of St Joseph's nursing home, Dr Mary Kelly.

"It's all highly confidential, you'll understand," boomed Murphy.

"We expect utmost discretion," whispered Kelly with a whip of her long curly black hair, looking around as if the room might be bugged.

Murphy continued. "As you know we've been testing and developing a new medication for hypertension, derived from an Amazonian herb. The results in mice have been very exciting. But we think we may have found an even greater benefit. In the course of our lab tests on mice, we found that female mice, to whom the medication was administered, became very drawn to the taste of male semen, and would attempt to suck it from the recently-copulated genitalia of the other female mice."

We then fed the manually extracted mouse-semen to these female mice and tested the effect on female mice. In fact we did a four-way trial: female mice with or without medication and female mice who had or had not eaten the sperm. The mice who hadn't taken the medication showed no interest in eating the sperm, and furthermore had minimal physiological response. But combining the medication with the sperm showed a host of responses across a range of factors, all of them positive. In particular, it was the elderly mice who showed the most benefit."

I scratched my balls unconsciously as I let all this sink in. Clinical research was one of my stronger subjects. I responded: "So, I know this medication has already been clinically approved and you want to see if you can replicate this synergistic cross effectiveness in humans?"

"Correct," replied Dr Kelly. "But we have a particular issue. We discovered that the semen must be fresh. It loses impact after only a few minutes. And it should come from young men. We think it explains the much-derided folk belief in the area where this plant is natively grown, of older women drinking the sperm of younger men for supposed health and longevity."

She looked at me seriously, one scientist to another. "This is a proof-of-concept study. Before we can agree to proceed, we need to check if you produce under clinical conditions. Let me introduce you to Margaret."

In the room next door, Mrs Gallagher, or Margaret, was waiting for me in a chair. She was a sweet-looking old thing of, ooh, I'd say around 80. I never asked. She looked small and frumpy. She wore a yellow cardigan and had short, snow-white hair. I shook hands and Dr Kelly made the introductions. "Margaret has been prepped and knows what to expect."

Silence. I looked around and pointed down to my crotch, ..". so, do I just..?"

"Uh huh," affirmed Kelly.

I think, "oh, who cares. It's fifty euros per pop, so here goes." I unzip and pull out my lad.

Up to this point in my life I'd been a pretty conventional kind of guy. I liked girls with big tits and fat arses, but you know what, I wasn't too fussy. It's not like I ever had lots of girls falling over me. I was a plain, awkward lad, and I took what I could get.

But older women? Never. However I was turned on by the financial reward I was going to get. The easiest money ever!

So, I yanked away, watched carefully by the two eminent clinicians and Mrs Gallagher.

"Are you close to orgasm?" asked Dr Kelly, as she appeared to type notes into her ipad.

"Yes, coming soon now," I responded.

"Ok Margaret. Let's get you ready."

I moved over to Margaret and she opened her mouth. I held my dick a few centimeters from her but Dr Kelly pushed me gently on my hip and Margaret opened her mouth so I was inside her. And not a moment too soon. Being careful not to hit her face with my wanking hand, I erupted. Margaret surprised me by closing her lips around my knob. Bam, bam, bam, I spunked off into her mouth. She gagged just slightly, swallowed, and gave my knob a little lick. We looked at each other and smiled. Murphy handed me a wet wipe and I dabbed myself and zipped up.

"Thank you young man. Collect your envelope at the desk and we'll see you here again tomorrow evening at 7."

The following evening, Margaret waved when I came to the room. I smiled and she rubbed her hands together. "I've been looking forward to this all day," she said sweetly.

I unzipped and started wanking, already semi-hard from the novelty of the situation. "Why don't I help you with that?" said Margeret and she reached out to gently fondle my balls as I wanked. Her touch was soft and caring and very pleasant.

"Oh, Margaret, that's lovely," I said dreamily.

"Could I request a kiss?" she asked warmly. "It's just that, I do love a kiss. It puts me in the mood, don't you know?"

I leaned towards her and politely brushed my lips against hers. I assumed she would be delicate and fragile, but she returned it firmly. She opened her lips slightly and I followed her lead. The full mouth contact felt wonderful. I sensed the lipstick slowly dissolve in the wetness. She moved her head slowly and we slid over each other. She held my lower lip between hers and I looked at her and we laughed.

Our kiss deepened and our tongues touched and sparked off each other. Her hand came up to cradle my face and I felt like a child. Her confidence was growing.

I caressed her chest with the back of my hand and she gasped. She took my hand in hers and clasped it to her bosom. I wanted to get a sense of her body shape beneath the frumpy clothes. I could feel the swell of her breasts, but I wanted more.

BANG went the door as Dr Kelly strode in. She stood with her arms crossed tightly under her medical jacket, looking stern. "That's enough of that now, you two. Let's get on with it, I haven't got all day."

Margaret smiled at me with a wink. I stood and masturbated into her open mouth as she caressed me.

"I'm coming Margaret," I groaned and I shoved my hips forward as her lips closed around me. My knees weakened a little from the pleasure of her tongue as I ejaculated. She swallowed and smiled.

"Thank you my dear," she beamed as I zipped myself and said my goodbye.

On day 3, Dr Kelly was accompanied by Murphy and two assistant researchers. One of them wanted to measure my cock, so I gave myself a few yanks to stiffen up. She put on blue latex gloves to check for firmness then ran a soft tape measure around the circumference and along the length.

My vanity took hold and I insisted that she press the end of the tape into my flesh to get a couple more centimetres added to the data point!

"It's big enough for me darling," winked Margaret, as she reached for my hand and slipped a small bit of paper into it. I snuck it into my pocket and had another delicious wank onto Margaret's tongue. The researchers watched, tapping their blue bic pens on their ipad covers and nodding in approval as Margaret swallowed my semen.

Later on in my apartment I read the note.

My dearest Mikey, come to me. All of my body is crying out for your touch. Room 742. Any time, day or night.

The clock said 10.30pm. I brushed my teeth hurriedly, had a quick shower and cycled to the hospital. I had to convince the security guard that I was her nephew and I ran up the stairs to her room.

She answered the door in a long chiffon nightdress. Closing the door gently behind me we embraced and kissed shyly. Her body was soft, slightly flat. When we took off our clothes I got the full measure of her. Her belly was puffy and loose, but you wouldn't say she was very fat, just meaty. Her breasts hung long down almost to her navel. Her hips extended wider than her shoulders.

"Can you make love to this old body?" she asked shyly.

I answered by kissing her papery skin, starting with her neck and throat, working my way slowly down. I stayed clear of her peak erogenous zones, saving them until later. She lay face down on her bed and I kissed her back, lightly stroking her buttocks and the backs of her legs, feeling the slightly raised cellulite beneath my fingers.

As I stroked up and down the cleft of her buttocks she gradually opened her legs and raised her hips. My caresses reached between her legs and she squirmed when I grazed her pubes. I licked the tips of my fingers and caressed her silky pussy lips with the lightest of touches.

After a few minutes she made to turn and I lifted her legs gently. She drew me in for a kiss and whispered, "help me get wet."

I buried my nose into her wiry silver pubes and drew in her wonderful nostalgic smell, something with roses. I ran my tongue along her slit and she murmured approval, then reached down to spread her lips for me. I dribbled saliva into her gape and worked it around with my inexperienced tongue, guided by her sighs and caresses on my head. I ran my tongue along her stiffening clitoris from her vaginal opening to its tip - again and again - feeling her passion build - sensing her lips softening and swelling.

"Just like that, don't stop," she whispered.

Her hips swayed, her butt muscles clenched and she pressed my head against her as she came. I felt incredible joy and pride. I was honoured that this beautiful woman would open her body to me.

We lay with our eyes closed, allowing her to take it in, my erection starting to hurt. She reached to her bedside locker drawer and withdrew a tube of ky-jelly lubricant. "When you get to my age you lead a little assistance," she winked.

Squeezing a few cc into her hand she pushed two fingers inside herself and worked it efficiently around her pussy's inner lips. Then she took another gob in her hand and said, "come, this is for you." I rose up on my knees and she applied it around my knob and mixing it with pre-cum, peeling back the foreskin and down the length of me. Throwing the tube back on the locker she lay back on the pillow and opened her legs.

Kneeling before her I rubbed my cock around her sloppy pussy, finding the hollow of her entrance and letting my cock sit there. I felt too big. "I don't want to hurt you," I said. But she smiled and pulled my hips towards her. "I might not be as fragile as you think, young man," she giggled. I entered her and her body opened for me. Slowly, gradually, inch by inch, I sank down inside her, hard as a rock and coated in sloppy wet juice. I held my weight above her, careful not to cause harm. "It's ok Mikey. I'll tell you if it hurts. I want you to take me now. I'm all yours."

She opened her arms beside her on the bed and her tits fell to the side. I lifted her butt towards me and started to fuck her, watching her tits sway with my strokes. My hips slapped against the inside of her legs and she grunted with each stroke, "ugh, ugh, ugh, ugh."

I couldn't last. The intensity of the eroticism was like nothing I had ever experienced and it overpowered me quickly. I came with an animal's roar and she had to grab my head to urge me to keep quiet. I stayed hard inside her for a while after I came, gradually softening, kissing her neck and moving gently, squeezing every bit of pleasure and sperm from the situation. I rolled her nipple between my fingers as I basked in the afterglow.

Pulling out of her slowly I reached for a towel to clean us off. I dressed and tucked her naked old body under the sheets. "Until tomorrow my sweetheart," I kissed her and left.

The following evening Dr Murphy met me at the reception desk. He stood proudly with authority.

"All our indicators for Mrs Gallagher have exceeded our expectations. All functional, cognitive and cardiac test results show dramatic improvements. We're very pleased and therefore have decided to move to phase two."

"Phase two"? I have to admit to a little trepidation.

"Now that the effectiveness of oral ingestion has been verified, we need to investigate other semen delivery pathways. The more conventional insertion point will be examined in this phase and beginning with a different subject."

"You mean..." I said, looking down to my crotch.

"Yes, vaginal penetration" he asserted as he led me into the clinic.

Dr Kelly was there to make the introduction to Mrs Christina Ryan, who was 85 and had moderate hearing loss. We shook hands and she smiled gently.

Dr Kelly swept back her curly black locks and spoke very loudly, almost shouting: "Are you ready to begin my dear?"

She led her to what appeared to be a large gynaecological chair and helped her onto it. She tilted down the back of the chair and helped raise her legs into the stirrups. Then she rolled up her long gown above her waist as her geriatric old fanny lay spread before me.

I felt slightly embarrassed on behalf of the old lady but she maintained a fairly neutral expression like it was no big deal. I guess she was so used to medical treatments at this stage of her life.

Kelly put on blue latex gloves and squeezing a large dollop of k-y lubricant into her hand started to apply it to Mrs Ryan. Murphy nodded towards my mid-region and I understood to take off my trousers and get myself ready. My cock was flaccid and would need work.

Christina stared at the wall disinterestedly. She was an unremarkable-looking woman in every way. She was medium height, neither fat nor thin, she had a head of sparse curly white hair. She wore some small amount of face makeup. I studied her very pale, almost blue, legs. Her loose skin hung down from her bones and veins textured the surface in places. Her nails were varnished and I thought it looked cute.

A thin patch of curly silver pubes surrounded her pussy and Dr Kelly was methodically coating all the surfaces of her meaty vulva with the magic ointment. Her genitalia protruded loosely from her body and the sight of Kelly's latexed fingers methodically working through the folds sent a surge of energy to my cock. I watched her thumb and forefinger grab what must have been her clitoris and repeatedly tug it gently away from her body. The old woman shifted in the chair and Dr Kelly shouted in her ear, "do you like that Christina?"

I was fully hard now and wanking away. Kelly glanced at me while Murphy made notes. Then she reached behind her and took a long silver object from the tray behind her. It was plugged into the wall and she explained it was a medical vibrator.

Murphy explained. "Unlike a normal carnal interaction, you will not be stimulating yourself with the friction of thrusting against your partner's inner. This is a clinical exercise and is NOT an exchange of pleasure. So you will wait until you are almost ready to ejaculate before penetration. Is that clear?"

I nodded to indicate my understanding as Kelly stroked the vibrator inside Mrs Ryan while rolling her clitoris between her fingers. Mrs Ryan might as well have been reading a newspaper, for all that her face revealed to me. But Dr Kelly's hands and her look of focussed concentration was bringing me close to the edge. She looked over and guessed. "Are you ready Mikey?"

"Yes," I gasped.

She withdrew the vibrator and I brought my cock to her pussy lips. I wriggled around searching for the opening and Dr Kelly took me in hand and brought me to the entrance. Not a moment too soon either. As I slid effortlessly into her, I felt the warm silkiness of her old pussy and the pulsing contractions from my prostate pumped my load as deep inside her as I could go. The pleasure was intense and I couldn't suppress a long grunt of satisfaction. Mrs Ryan turned her head away from the medical diagnostic charts on the wall. We caught each other's eyes and smiled together.

"Don't pull out yet" said the two doctors in unison. "Just move inside her slowly and work that ejaculate around. Make sure it's fully absorbed" ordered Murphy.

No complaints from me. I blissfully moved around inside her and absent-mindedly stroked her inner thighs with my finger tips. Kelly had taken her fingers away and was updating her records on her ipad. Murphy had turned away to find his diary and nobody saw Christina take my hand in hers and squeeze it gently.

"Ok thank you Mikey, same time tomorrow then" said Dr Kelly as she put her notes away. I slowly withdrew, dressed and left.

The following day Mrs Ryan was waiting in position when I entered the lab. Her clothing up around her waist, she was applying her own lube and circling her clit slowly as she watched me undress, a smile across her face.

"Christina would like conventional phallic arousal," stated Murphy, as he peered at me over his expensive glasses.

"Er,..." I mumbled.

"Normal coitus, my boy. As you normally would."

Not wanting to explain that, outside of this makeshift sex lab, I didn't get enough sex to have a 'normal', I decided to just bang away as I wished. The sight of Christina rolling her slippery clitoris beneath the flesh curtains of her old cunt turned me on, and after a couple of pumps I was hard and ready. Stepping forward, I peeled my foreskin back and presented my cock. She guided me to the opening and we both sighed together as I slid inside. I locked into her twinkly eyes and let the sensation of being inside her wash over me, before starting to move. She resumed her masturbation and I watched her old spotted hands circling the hood of her clitoris, the swelling of which was showing.

I felt the pressure of her movement on the top of my cock and we found a rhythm together. I took it slow and easy. This was one that I wanted to drag out.

Christina's face was flushed and full, in contrast to the wan complexion of the previous night. Her breathing gathered pace. Murphy and Kelly looked at each other and called a halt to the operation.

"I'm sorry Christina, we need to be extremely careful now," said Kelly.

"But I feel absolutely fine dear," said Mrs Ryan. "Please let me go on."

But the two physicians were concerned about her health. I had to withdraw and stand there like a fool with my raging hard-on while they conferred. Talk about a buzz killer.

It was decided to fit Christina with a cardiac monitor. And so, after attaching her electrodes, and with her cardiac waves displaying on the screen behind her, we resumed our copulation. The intensity of the passion had diminished and the orgasm I was sure she had been headed for eluded her. I came inside her dutifully.

On the plus side, the cardiograph demonstrated the robustness of her health and the next night we fucked normally. As I approached orgasm she pulled my head towards her and we kissed deeply. Her wet mouth sent me over the edge and she wanked herself furiously to her own climax as mine was subsiding. Sweat was trickling down my spine as I watched her clench. Murphy and Kelly were tapping out notes intensely.
