In Training and at Stud
Well, that pretty much set the pattern of my life for the next two years. Rachel was very pleased with me when I got home that night and handed her the letter for her that the Doctor at the clinic had given me for her. She had me stripped and standing in front of her as she read it.
"Dr Blackwell tells me that you are accepted on the clinic's stud register and compliments me on the quality of your sperm. She says that with regular controlled ejaculations and the right diet and this zinc supplement, your volume will increase too." Rachel told me.
She fondled my balls idly, rolling them in her long slim fingers and cupping them in her palms.
"Do they ache now after your orgasm?" she asked me.
"Only a little bit Mistress," I admitted.
"Hhmm," well they will strengthen with the exercise, "You will only ejaculate at the clinic, but you will masturbate every day under my supervision and I will massage them for you as you do it. I have a reputation to maintain at the clinic, I always send them the best trained sperm donors."
My balls did ache after Rachel had finished with them that evening. She encircled my sacs with her finger and thumb and gently coaxed them down and away from my body, stretching the soft skin that contained my two hard testes so that they hung low. If she'd released them at that point, they would have swung low like two pendulum weights, but my cock stiffened alarmingly and tried to draw them back up again. Rachel was relentless though and traced the hard nuggets with hermher fingertips, squeezing and pulling them.
"Wank yourself." she ordered.
I did so gratefully, despite my big orgasm earlier, my cock was rigid and stiff from Rachel playing with my balls. The stiffness in a man's penis, the tension he experiences at the root in his groin is the most fantastic feeling a male can have, especially when a female is the cause of it happening. I quickly felt the basic urge to offload my sperm.
"Yes," Rachel encouraged, "yes, go on, spurt now. Quick as you can."
I did so and felt my balls jerk and jump in her firm grip as I did so. Thick white sperm flopped out in lazy spurts and I was delighted when Rachel caught it in her free hand.
"I know you think that you are not to wank between your sessions at the clinic, and that is true, but you are not due back there until next Friday and Dr Blackwell has written to me to advise that you be thoroughly exercised up until next Tuesday. She wants that all of your donation on Friday be freshly made, so we are going to wank you steadily for the next four days. Keep on wanking now." Rachel told me.
My penis was slackening slightly by now, but her instruction stimulated me and slowly I felt full erection returning. As I wanked, Rachel sat back and I was delighted to see her spread my recent ejaculation into both palms and slowly work it into her fingers like a hand cream.
"The best hand cream in the world she smiled at me. And there's not quite enough here, give me some more, come on, do your sperm quickly now."
I masturbated furiously now, eager to retain my stiffness and then, as I knew would happen, I felt that deep sensation that told me that my orgasm would not be long. Six or seven strokes later and I was on the brink. Rachel held out her hand knowingly and with a further half dozen strokes I delivered another orgasm into it. A further small puddle of white joined the rest as my balls racked with seizures and a deep ache set in.
"You're almost empty now, but thats not enough." Rachel instructed.
She worked my fresh ejaculate into her fingers in a lazy cat-like way.
"Twice more tonight I think, " she mused.
I continued wanking. My prick was no longer rock hard. Rachel made herself comfortable and turned on the TV, settling back to watch.
"Keep wanking yourself." she told me.
I stood by her chair abusing my cock. Slowly her right hand reached out and curled around my balls, fondling them. My stiffness returned, my wanking became furious as I struggled to comply with her request for more. A female had demanded my sperm and I was unable to refuse. I orgasmed. My thigh muscles trembled and weakened and my balls jerked in her hand. Only a small bead of semen appeared which she wiped off with her thumb.
"Don't stop. One more now, then you'll be drained. Your orgasm becomes more intense as your balls empty and it will be easier for you to have another."
It wasn't that easy. I wanked for another half hour before any feeling of orgasm returned despite her constant grip on my balls, now swinging limp and loose from their strain and from the warmth of her hand. She noticed the change in me.
"Come on then, one more time. You'll come dry this time and then you'll be empty. You can go to bed and nurse your aching testes. Then we'll start over in the morning."
And so it was. When I came that last time, my balls writhed and every spasm was delicious agony as the intensity of the orgasm racked my body. An orgasm far more intense than when I was delivering my full cream, an orgasm more like to those that I'd observed in Rachel when I'd licked her out. My prick jerked and reared and my glans gaped vacantly like a dying fish struggling for air. My balls were quite empty.
Each day, Rachel made me repeat this. Each day, I wanked until I was dry. Five times on the Saturday. Six on the Sunday and seven on the Monday. I was exhausted but deeply fulfilled. On the final day of the training, I managed eight orgasms each time producing some thick white semen and only on the eighth, balls throbbing with a deep ache, did I rear wildly and produce nothing.
When I turned up for my appointment at the clinic on that first Friday, my balls felt pretty good. Rachel had exercised them thoroughly and fed me my zinc supplements each day, and now, three days later they were full again. They were sufficiently full that I knew that release was necessary.
I cannot adequately describe to a woman the feeling a male has when his balls are full. There is a deep seated glow in them, a silky heavy feeling, and a constant pushing demand for release that over-rides all other considerations. Women will know that a man in this state thinks with his cock, but really it is his balls. I'm not talking about the casual wank, fuck or orgasm, but the heavy insistence of a male whose balls have been brought to the peak of breeding condition and must offload his seed.
I entered the main entrance of the clinic and was greeted by Natalie behind the reception who smiled at me sweetly. She was absolutely stunning, petite with long blonde hair and a cheerful open disposition. My cock thought so too as I felt it stir.
"Hello K," she greeted me, "as its your first visit, let me show you where you go in future. This reception area is really for our female clients and we don't let the males in this way." She took me through a door and led me around a corridor to the back of the building where she showed me an altogether lower standard entrance hall with simple waiting room chairs.
"You come in that door at your appointed time and wait here. One of the staff girls will call you in for your session then. Dr Blackwell will deal with you today as its your first donation." she told me matter of factly.
Dr Blackwell did appear shortly after that.
"Hello K, I'm glad you've arrived on time, but of course we expect males from Rachel's string of studs to be well behaved. Come on through K." she told me.
The room was warm and clean but very sparse and clinical. A low table dominated the centre and a simple chair was placed by the wall. On the table were various things you might expect; tissues, wipes, a towel and a box of disposable gloves. Other things had functions not immediately obvious such as a small box labelled "Sample Tubes type 905" for instance.
"Strip naked for me please K," Dr Blackwell asked me, indicating that I was to place my clothes on the chair. No privacy then, but what should I expect really.
"As its your first time here, I will extract your sperm this time K." Dr Blackwell told me. "So that we don't have any mishaps or misunderstandings though, I'm going to make sure your hands are out of the way. I don't expect any difficulty with you, I'm sure Rachel will have trained you properly, but some of our bigger hunkier studs can get very excited when they are erect.
She put on a single disposable glove on her left hand. "You may have some preconceived ideas of how this things work, but I need to tell you that we do not just leave you in a room on your own with a pornographic magazine. The delivery of your sperm needs to be supervised and observed so each time you attend here you will masturbate yourself while I or one of my assistants supervises the operation.
She took a damp tissue from a box marked as antiseptic wipes and proceeded to clean my shaft with it very thoroughly. Not just the shaft but under the foreskin and behind the crest and all of my glans until is shone wetly. This of course had the effect of stimulating me too and so my erection was rearing and surging in her hand eagerly.
"Good boy," she said soothingly as her hand rippled my foreskin causing me to rear up wildly, "now, take yourself in hand and masturbate for me now please."
I wanked briskly while Dr Blackwell extracted a sample tube from the box and uncapped it ready.
"Come along K, " she urged me, "I need your sperm quickly. Do you sperm for me now please. Good Boy!"
