Semen Collection Clinic

This is my first story here, please be kind.

I work in a fertility clinic here in the UK. I don't do anything medical, I'm only a receptionist.

When a handsome man comes in for fertility assessment, I often daydream. Working in the clinic has given me strange fantasies. The men in small rooms, cock in one hand, small cup in the other. When they cum, they try to make the whole load of sperm go into the cup without spilling anything.

The story below is only fantasy.

Semen Collection Clinic

In my fantasy clinic, we have many fun ways of extracting the sperm. The latest method is an automatic cum collector. They look like small cash machines, built into the wall. There is a soft pink silicone insert. The inserts don't look like pussies, they are clinical and plain, with just a round hole in the middle. They are made for one time use. It's my job to follow the patient to the machine and prepare it for use. 

I power on the machine, cover my hands with medical latex gloves and ask the patient to strip naked from the waist down. I insert the silicone part into the machine, it beeps and blinks green when I have inserted it correctly. Then I lube it up with our special lubrication jelly and I explain to the patient what will happen, as he is shyly taking his pants off.

"When you're ready, sir, you can simply insert your penis into this hole here. It's soft and lubricated and body temperature."

He is standing next to me, naked from the waist down. His cock is not soft, not hard, but definitely waking up, a little bit chubby. Very few men are hard at this stage, it's a bit embarrassing and most men are quite nervous. 

"You don't need to have an erection to start with, you can go ahead and insert right away, there's a gentle suction that helps pull your penis inside, sir."

He steps up to the machine, pawing at his penis. The machine adjusts its height automatically as he steps up to it, the sensors working out his height and exactly where his penis is.

As he guides his semi-hard cock near the pink hole, nothing happens...

"Ah, let me do a manual start, just one minute, sir. These new models are a little bit difficult to get started sometimes."

I use the touch screen to go into the menus. I select the menu for penis type. I press uncut.

"May I ask, how big would you say you are at maximum erection, sir? Have you measured?"

"Um... I think at least 7 inches, but it's... It's been years since I, uh..."

"That's fine, sir. I'll select 6 inches here, because the machine works better if we select a smaller size."

In reality, we select a smaller size because we've found most men tend to exaggerate and boast about their size. In unclear cases, we can induce full erection with a stimulating lotion that is applied to the base of the penis, and then we can easily measure the exact size.

"There we go, now try again. Just move your penis so that it touches against the opening and it should gently guide you in."

The machine sucks his member in with a slurping sound. He flinches but I reassure him.

"There we are, that looks good. If you're comfortable, I'll turn it on now. Wonderful. Now, you'll feel the machine starting to move rhythmically. It's all perfectly safe, there is nothing inside that can hurt you. Please use the handles on the wall there to hold on to and just try to relax. When the time comes, don't fight the ejaculation. And don't push yourself in and out, the machine handles the motion. Stand still during the whole procedure, alright sir?"

The insert whirrs and pulses around his cock, sometimes pausing from the in-out-motion simulation to rotate slowly, then it goes into the tugging/sucking mode for a while before simulating in-out motions again.

Every now and then I have to remind him.

"Sir, please remain still, don't move your hips. The machine is working. You're doing very well."

It doesn't take long. Usually no more than three minutes. The inserts and motion patterns are designed to feel amazing for cocks of any size and any shape. They tested these C6900 machines on over 3000 men in Germany, to figure out the optimal patterns for all different types of cock.

He glances over at me, blushing furiously, gripping the handles on the wall.

"Don't fight it, sir." I give an encouraging smile.

"I'm, uh, ahh-a-ba-aba-ahhh..." 

"I know. Stand still during the ejaculation, sir." I step behind him and put my hands firmly on his hips. Some patients need this. They can't control themselves near orgasm and their monkey brain takes over, so they start to buck their hips as if they're having sex with a woman.

I can feel his body shaking and he keeps grunting throughout his orgasm. 

"Please remain still and don't pull out until the machine flashes green, sir. Now you've ejaculated fully, the machine will clean your penis while you still have an erection, and it will apply a mild lotion for rehydration of the skin. When the machine shows the text 'Collection Completed' you can pull out your penis gently and get dressed. No need to wash your penis, as I said the machine does that for you, sir. Pull out the silicone insert and dispose of it in the rubbish bin right there, please sir. See Julia at reception when you're done, okay? Take your time, sir."

I close the door behind me and walk into the waiting room. I look down at my clipboard.

"Mr. Harrison for prostate health check? Please follow me this way to examination room 4, sir."
