The taxi hired at Heathrow took us first to Julian's place where before he got out of the cab, gave me a kiss in the lips and thanked me again for the holiday and we were driven off to leave us outside Carol's small flat.
`As much as I loved the villa and the fun we had there, it's still nice to get home,' Carol said when we entered the flat. This brought to mind the two houses that I had, neither of which I had really called home. Also of the home where my parents lived and would expect me there in six weeks time when it would be my twenty first birthday.
Needless to say, we went straight into the bedroom and stripped off, showing each other our brown bodies and me with a full erection that Carol kissed as I got onto the bed with her. With me between her legs using my mouth and tongue, gave her the first orgasm and then entered her and brought her up to her second one as I came at the same time.
We later had oral sex with her upside down on my body as she sucked and chewed on me as I plated her till we both came and had her swallow my sperm before licking me clean. Where in Spain, we only covered ourselves with just a sheet, here, it seemed so cold that we cuddled under blankets to warm each other up as we fell asleep.
With me having nothing better to do, went with her to the clinic and for the first time, met Doctor Parker. I had gone into Carol's office with her when, a few minutes late, the doctor came in and we were introduced.
It's a pleasure to meet you in the flesh Mr. Oates instead of in vitro,' he smiled, shaking my hand. Lovely specimens you have given us. It's kept those in the lab very busy which leads me to a question that I would like to ask and hope that you would accept,' and I wondered what he had in mind. `We would like you to agree to letting us use your sperm in building up our sperm bank. We don't pay for this as we ask for it to be given on a volunteer basis to help with couples where the man is impotent. Would you agree to this?'
I saw Carol behind him give a smile and saw her nod her head knowing that she would like to help me in giving my sperm for this bank of theirs.
`I'm flattered you've asked me and would be delighted to help,' I replied, getting a big grin now from Carol.
Thank you,' he said, shaking my hand. Carol will bring you a form to sign. It's just a formality saying that you give it free of any restraint because you will not be told who the recipient might be. In fact, we are not told either,' he said shaking my hand. `Now apart from that, we would like you to stay on for a four week testing that we are doing on gene transference.'
`What does that involve?' I asked.
`Carol will explain later as it's rather complicated,' he said.
Yes Randy,' Carol said, looking at me. Why don't you go to your old room and change. You must be hot in your street clothes.' This I agreed to for I was indeed feeling the heat of the clinic, it being kept quite warm for comfort. It seemed strange being the only one in the sitting room for the guinea pigs as I carried on to the second room on the left to have a shower first before putting on the pair of shorts and T shirt provided. I didn't wear the slippers as I preferred feeling the carpet beneath the soles of my feet.
I went back into the sitting room where it held a television set and lots of videos and a pool table. This I played on, knocking and pocketing balls until I heard the tannoy ping.
`Randy to room one please,' came the crackly voice of Carol. I knew what this meant and quickly went out into the carpeted corridor. Opposite was room one and room two was to the right and the office was off to the left, and all three were joined by interconnecting doors so that the nurses could go through without using the corridor. Room numbers one and two only held an examination table and a couch and knew that we would be using that couch for sex.
She had a big smile on her face when I walked in and shut the door behind me. She was now wearing her white, short sleeved nursing coat that she started to unbutton and opened it to show me that she was naked underneath. Seeing those lovely tits on display again as well as the trimmed bush between her thighs gave me an instant erection and I grinned back at her as I quickly took my two items of clothing off to show her that I was up and ready.
She quickly laid herself down on the couch with her legs wide open and I went straight down in between them and began to lick between those lips that hid her vagina. She gave out a moan when I parted them with my fingers and used my tongue on her clit, running it over it before pushing it into her vagina. The only way to rasp the clit with your teeth was to bury your nose into her pubic hairs and sometimes cut off your breathing in doing so. But I was used to this and it didn't take long at my administrations in bringing her up to an orgasm.
As I've said before, I was used to plating a woman like this and used my shoulders to prevent being squashed and denied oxygen during the throes of this orgasm. I would get a good taste of her as it flowed down and out and would always get a lot of it smeared round my lower cheeks and chin. I sometimes rubbed my face on her stomach as I moved up her body or on her own face and lips as I covered her with my body, letting my erect prick slide up the wet path and enter her.
I got another groan from her and could see the sparkle in her eyes as my cock filled her, her legs coming up high against my thighs to get the most of me inside her. It was lovely to feel her inner body heat as she used the muscles inside to flex themselves round my throbbing cock which I would twitch in response before beginning the process of fucking her.
Now being used to fucking Carol, I was able to hold back my coming as I moved myself in and out of her, pulling out sometimes to let the head of my cock move against her clit before moving back inside and soon brought her up to her second orgasm. Bucking up to me as she came with me managing to keep myself inside as I came at the same time as she acted as a human vibrator beneath me.
We were both panting heavily when we came to a stop, her muscles once again flexing themselves around me as we smiled at each other as I eased myself off my elbows and laid my sweaty chest on her sweaty breasts as we then kissed.
It's too later to take a sample now,' she smiled up at me. This was because I had to use a condom for this sample of my sperm for the lab to use. But we will get one later.' I then wondered if in getting this sample I could have Julian up my backside, fucking me as I fucked Carol, but I didn't think that she would agree to this as she wouldn't let Julian see us fucking when we were at the villa. He had though she didn't know that he had watched us from inside as we did, him jerking himself off as he watched me humping her.
She gave out a groan as I pulled my now deflating cock out of her and climbed off and put my shorts on and carried my T shirt in my hand as she too put her white coat back on and we went into the office where she took a blood sample for the lab boys to work on.
The other three guinea pigs,' she was now using this term for us volunteers, will be arriving in the morning, but only for five days. A father with his two daughters,' and she gave me a hard look, `and you're not to touch them.'
`Not even shaking hands?' I asked keeping a straight face.
`You know very well what I mean you randy sod,' but smiled as she said this.
As I was the only guinea pig there, Carol and Julian had lunch and dinner with me that first day back, me being put back on my diet by Carol and so for the first time, had a lonely night in my bed. It was just after breakfast when the other three were shown into the sitting room. A tall thin man followed by two young girls and we were introduced with them being given my name as they told me theirs.
`My name's George Edwards and this is Joanne and Elizabeth,' he said shaking my hand. I then shook Joanne's.
`I've shortened it to Jo,' she said. Another Joe I said to myself, different spelling and not a male. That Joe being bi-sexual who I did get to have sex with after being given my double dose of female hormones by mistake.
`I'm called Beth,' said the younger of the pair and I wasn't far out in their ages I found out later with us talking to each other. George was forty seven and had been a Captain in signals but had not long retired from the army. Jo was nineteen and Beth just sixteen and all three were between jobs at the moment which was why they could be at the clinic.
George was the first one out from getting changed and I learned that he'd not long ago, lost his wife and that was why he retired from the army to look after his daughters. Jo and Beth came out shortly after and I could see quite clearly that they were not wearing bras beneath their T shirts and Beth was quite big up top I noticed.
After lunch we all gave up some blood and they also had some other tests that didn't involve me and we played pool in between and after dinner before retiring for the night. Another lonely one for me, but only that one.
The next day, I got to fuck Carol during the morning in room one and got her to agree to me having Julian see to me in the afternoon. He was delighted when I asked him to help me get my sperm sample and couldn't get into room one with me quick enough. He knew how I wanted it and had an erection already when he took off his white coat to show that he, like Carol, stayed naked underneath when in the clinic.
He knew he couldn't suck on my erection before giving the sample and rolled the rubber down over my cock before I got onto the couch with him getting on behind me.
`I love this,' he crooned as I felt his hardness expand my rear entrance as he pushed himself up into me, wearing a condom too. I loved having him there inside as he began to move and fuck me. I groaned and enjoyed the internal massage I was getting as he moved himself in and out and loved his weight on my back as he reached underneath and began to use his hand on my covered cock. I was in heaven at having him throb inside me as he worked his hand on my erection and making me come into the condom as he then came inside me at my cry as I filled mine and he filled his.
I also gave out a cry as I felt him pulling out leaving a vacuum behind. He pulled his condom off with some tissues before pulling at the one I was wearing, twisting the bulbous end to seal in my sperm before pulling it right off and knotting it. This was put to one side as we both lay on the couch, upside down to each other so that we could suck on our still erect cocks to suck out the residue of semen to swallowing before licking each other clean.
So that was two samples I gave that day to the lab boys but they didn't get the other two. Dinner was served up again by Julian that evening, the menu I had given up ticking what I wanted to eat for it was Carol who saw to what I ate, keeping me on a strict diet. After which, the other three settled down on the settee in front of the television and put on a video. I'd already seen this bad movie and was knocking the balls around on the pool table.
They had been watching it for about fifteen minutes before Beth got up.
`God, this film's terrible,' she said and moved round and came up to me. Now I had stopped to see where the film had got up to and saw two women dancing together. This brought to mind the sight I had once of seeing Sheila and Fiona dancing naked together. Their breasts being moved between them as they kissed in their drugged state before they fell to the floor to have female sex. This brought me up to a semi erect position and was miles away when Beth brushed past me, the back of her hand moving across my front and knocking the pool cue from my hand.
Sorry,' she said, and knelt down to pick it up but also pressing the side of her face to the front of my shorts and couldn't help but feel what was inside them. Just this brief contact made it rise up even more and she smiled at me as she got up and handed me the cue. I'm sure my face was red at having her feel that I was hard inside my shorts. Can we have a game?' she asked.
Now I'm not sure if she was asking about pool or was it an innuendo for another kind of game, but nodded anyway.
`Must go to the loo first,' she smiled at me and went off to her room while I tried to mentally calm myself down as I got all the balls onto the table and into the frame before she came back into the sitting room. I noticed straight away that she had changed her T shirt and had put on a boob tube. That elasticated piece of material that stretched around her chest, enclosing her tits but at the same time, emphasizing just how big they were and this aroused me once again. I think I spent more time watching her tits get squashed as she leaned across the table instead of seeing where the balls went and lost the first game by not paying attention to the right objects.
We played ten games, finishing up a draw when the movie finished and George got up and stretched as he announced that he was going to bed. Jo said the same and Beth laid down her cue on the table.
`Thanks for playing with me,' she said with another innuendo and a lascivious smile on her face. It was her that was playing with me I thought, teasing me with her tits.
`You're welcome,' I said, my eyes riveted on seeing that her nipples were erect and so noticeable, pushing out the material that covered them. I stayed standing on the opposite side of the table so that she couldn't see how the front of my shorts were being pushed out by the erection I had. It was only when I was left alone did I go into my room and quickly had a cold shower before drying myself and getting into bed.
I was only in it for ten minutes, getting another hard on thinking of Beth's tits when the door to my room opened and then closed.
`Who's that?' I asked, sitting up and reaching for the lamp switch.
Shush. It's me,' came a whispered reply. Don't turn the light on,' and I heard the whisper of what sounded like a dressing gown being dropped to the floor as the cover of the bed was pulled back and I felt the naked body of what could only be that of Beth coming alongside mine.
Did you enjoy what you could see earlier?' she said as I felt her breasts getting squashed against my chest as she then kissed me. I felt what you had and I wondered,' she was saying as her hand moved down my chest and over my stomach, and...oooh, I was right,' as her hand took a firm hold of my erect cock. You're as randy as your name and I'm feeling randy myself,' she said, kissing me again. The way her hand was moving on me said that mine wasn't the first one she'd handled and pulled it away as I rolled her over onto her back, still kissing her.
The covers of the bed moved down as I kissed my way down her body, Taking my time to kiss and nibble at the nipples of her tits before licking all round each breast before carrying on down. Kissing and tonguing her navel and then down in between her legs that she had opened.
The small amount of pubic hairs she had were as soft as a mink coat and my nose passed on down until I could use my tongue between the labia lips. She squirmed at the first touch of my tongue inside them and opened her legs even wider as I began to really get down to the business of bringing her up to an orgasm, which was long and had her almost screaming out in delight when she had it. Bucking beneath me as I tried to keep my mouth down between her legs as her thighs tried to close to hold me there.
That's the first time I've come,' she panted and was pulling at my hair. I moved up, wiping my chin over her stomach as I kissed my way up till she felt the head of my erect cock touching the lips of her sex. I'm glad you didn't masturbate,' she said as she pulled at my shoulders and I moved my cock up inside her to a gasp. Then I got a shock when I felt myself break through her hymen.
`A virgin!' I cried and suddenly pulled out for I wasn't wearing a condom, having forgotten to put one on before I'd started to fuck her.
No!' she cried out, trying to hold me on top of her as I rolled off. I want you Randy!'
`But you're a virgin,' I said.
`Was! But not now, you've changed that for me. Pleeese! Don't stop now,' she said with what sounded almost like a sob.
`Are you on the pill?'
`No. We were told not to before coming here,' she replied.
`Well I'm putting on a condom then if you want me to carry on,' I said, rolling over and getting one out of the bedside drawer and getting it out of its wrapper before rolling it down over my erect cock.
She gave another gasp as I entered her for the second time and her arms came up to hold me when I was fully up inside her.
`It feels bigger that it looks,' she gasped, her muscles playing havoc up and down the shaft making my cock throb.
`Why didn't you tell me you were a virgin, for you sure fooled me in the way you acted,' I said, loving where my cock was.
`You might not have wanted me if I had,' she said.
`Well I don't know about that now. It's no use crying over spilt milk,' I said.
Or a split hymen,' she said and I'm sure she had a smile on her face. Now that you've turned me from a girl into a woman, fuck me as I wanted you to do from my first seeing you.'
This I complied with and took my time in moving my hard cock up inside that slippery hot cavern, getting little squeals of delight as I did so, her legs coming up higher against my sides.
`What a man!' she breathed out in gasps as she began moving under me as I guessed she was getting close to having her second orgasm. That wasn't long before she really started bucking underneath me as I kept on moving inside her but began to really mash my pubics to hers as I went into a ramming mode and when she gave out a scream and went rigid except for her hips, I let myself go and came at the same time.
What a man!' she said for the second time as we came to a halt. What a fuck!' as she pulled my sweaty chest down onto her sweaty breasts, squashing them. I didn't know it would be as good as this,' her insides still making my cock vibrate. I'm glad I waited and not let one of the boys change me into a woman.'
`I guessed you'd been with someone in the way you took hold of me,' I said.
`Yes, but only played with their little cocks, jerking them off as I wouldn't let them fuck me. But feeling you out there, knew that you were a real man and not a boy with a thin pecker. I've even sucked on them but that was as far as I would go and would only do that after they had licked me. But none of them gave me an orgasm like you did in doing this.'
Let's put her to the test, I said to myself as I moved up onto my elbows, our chests coming unstuck with an obscene sucking noise and began to pull out.
Noooo!' she cried as she felt me leaving her, the inside muscles working like mad to try and hold me there, but out I came and rolled over onto my back. I didn't like that part,' she said, rolling onto her side and moving up onto an elbow and leaned over me.
`I want you to do what you did for little boys. You're a woman now so suck on a man now,' I said, putting my hand up to her head and giving it a downward push.
She must have liked sucking on the boys for she didn't object and moved down the bed and took the head of my still hard cock into her mouth and began to suck and squeeze me. It was nice to have a strange mouth on me and loved the way she used her tongue in licking the exposed head.
This is the first time I've tasted myself,' she said, briefly having lifted her head up off me before taking me back in. She kept on sucking until I began to wilt and then finally released me and gave the head a kiss before moving back up and kissing me. I even got a taste of you too, and it wasn't as bad as I thought it might be. When can you fuck me again?' she asked, still holding my now deflated cock.
`In about an hour,' I said, and I think it was a bit before that time that she roused me again by playing with my cock and balls and we fucked for the second time.
She stayed half the night in bed with me before leaving to go back to her own room, but came into my room for the next three nights where I then had the bedside light on to see her naked body properly and for her to see mine. After having had sex for the first time with me, she wanted it more than ever now and we fucked in as many different positions that you could think of.
It's just as well that I was young and fit for I still had to see to Carol to give her my sperm samples and have Julian fuck me to get even more for the lab to play with as well as let their sperm bank be added to.
Friday morning came and after breakfast, goodbyes were said, shaking hands with George and Jo and had Beth give me a kiss on the lips which brought a frown to George's face and guessed that he was thinking that I'd bedded his youngest daughter.
