Your testicles have been working all day, cell by cell, producing a flood of sperm. Each little tadpole of vital fluid has rushed from its birth in the meaty cylinders in your scrotum, through miles of fine tubing to be ready to explode from your penis under the right stimulation.
All day long they have been sitting inside you and waiting. They are getting restless, hoping for activity. You can probably feel them pushing up against the inside of the sac storing them inside you. They make you feel restless too, a bit on edge, needing some release.
But you hold off. You resist the temptation to go online and call up your favorite images or find a story that could help relieve the tension. You pace around hoping to reduce the pressure some.
Finally it is time. You get in you car and drive. After knocking on the door you enter a room with a receptionist who takes you to another room and tells you to take off all your clothes, after weighing you, checking your height, and your vital signs. You sit in the room on an examination bed, the changeable paper wrinkly against the nude cheeks of your butt. As you wait you can feel the air-conditioning push up your legs and tickle the fine hairs of your scrotum. You are excited and you can feel your penis thicken. But you will it down, by thinking of work and what you still need to accomplish. Foot steps outside bring you back to the room and how naked you are under the thin, light blue gown open at the back.
He enters and has you lie on the bed on your stomach, your bottom exposed to his gaze. You feel his hand on your cheeks as he says to you that there are only a few tests they must do for you. He lets you know they are videotaping the examination and tests so that the video can be used in medical training. At first you feel slightly invaded, but then you can feel once again blood rushing to your groin with excitement about the young medical students who will see you exposed and vulnerable on the examination table.
He puts on a latex glove, adds lubricant to his fingers, and pushes against the tight ring of your anus, closed into a fresh bud. As he pushes you relax and your anus opens like a flower. His fingers enter you and he anoints your insides with gel. He removes his finger and you feel a prickle on the edges of your anus as he touches you with cold steel calipers, so he can measure the size of your slightly opened bud. They poke, a bit like pins, stinging into your flesh. Then they are gone. "Very good. Very good" he says. You feel his fingers enter you again as they stretch and push, searching for your prostate.
The he inserts something else. At first it is a little cold. But then it warms from your own heat. Your whole mind is on what he is doing back there. You cannot see it but you feel every touch, every poke, every movement, with an unusually heightened awareness.
Suddenly your body lifts from the bed in surprise. He has turned something on and it vibrates with in you. Your body feels like a thousand currents flow through it and across it. You tense and you fall, tense and fall, as he moves the instrument in and out.
"Good, good" he says and you fall back on the bed, your stomach heaving with feeling and you feel the puddle of liquid under your groin that escaped from your penis. It is hard, harder than you remember it, aching underneath you to be touched, to find release.
As your body rests a moment from the invasion you hear him puttering around on a tray near the bed but out of your vision. Things rattle as he pokes through what sound like metal and rubber instruments. He turns to you again and soothingly runs a hand along your back and over your buttocks before asking you to spread your legs a little. He takes one thigh in his hand and pulls it aside, taking the time to caress it briefly. Your testicles hang against the paper cover of the bed. You can feel the sudden change of temperature against them and groan lightly from the sensation. You can feel him looking at them and studying them from behind.
He grabs them in his hand and massages them. You can feel him separating each of the strands of tubes within them along which your sperm travels. He runs each of your testes through his finger. You feel him touching all the edges of their spongy roundness, looking for unusual spots. "Good" he grunts. "Everything is good"
He pulls on them and you feel him slip a band around them, tightening them and separating them from your body. After the band is tightly in place, he massages your scrotum gently to calm you, but you rise from the bed from the sensitivity of your gonads. He runs his hand along the shaft of your penis, pausing for a moment where it widens and then runs his fingers over your glans, taking the drops of moisture from the tip and spreading it over your rigid penis.
Every sensation is heightened within you. You feel his fingers crossing every cell of your penis as if each were a separate organ.
He slips something over your penis and pulls it down to the base. "We need a sample" he states simply and seemingly dispassionately. But you can hear his voice is becoming a little husky.
After making sure the receptacle is in place and well attached he slides his curved hand up and down your penis a few times as your entire body tightens. He stops, drops your penis, and begins massaging the area behind your scrotum. The sense of immediate release diminishes in you but you feel his touch spreading along the pathways of your nerves until your whole body becomes sensitive even to the slight movement of the air in the room. He continues his gentle rubbing between your anus and scrotum. Your penis stiffens even more, something you did not think possible and you can feel the precum flowing from it into the receptacle. The head of your penis is wet, surrounded by your own moisture.
Again he touches your penis. You feel like you will cum at almost any minute. He slides the sheath off your penis and shows the receptacle to you, filled with your nectar. "A good amount" he grumbles. "Perfect for the laboratory analyses we must make."
You fall back on the paper. Your nerves are charged. You want to cum. "Please," you want to beg, "please make me cum. I can't wait any longer." But you say nothing as you hear him emptying your liquid into a container.
The door opens and you turn your head to try to see, but you can't without lifting up. So you just fall back on the bed. Under you, you feel the moisture that had dripped from your penis. It formed large round spots that now press against your abdomen.
"Is that the sample" the new person queries. "I will take it to the lab. But I need to let you know the feed has gone fuzzy. I do not think we are taping any more." He responds "Ok. Bring them in then."
You are nervous. You wonder what is going on. But he stands away from you fiddling with more objects. You hear their dull rattles and knocks as they push against each other. Then you hear clicking on a keyboard, a rapid tattoo of sound. Your body is coming down from its high. You still feel on edge, but tiredness is spreading within you. You want to sleep. Still the clicking of keys.
The door opens. You do not lift your head. You are half asleep by now, but you hear the shoes of four or five persons as they click against the tile floor. They gather around you. You can see two of them out of your half opened eyes. They are dressed in white coats and look like they are maybe thirty years old. An eagerness flirts with seriousness and distance in their faces.
Again he caresses your buttocks and says "Now for the next test. Lift up please."
You slowly lift your hips. You feel him running his gloved finger along the edge of your anus. With each passage it feels like it glides more. Your anus is slippery. Blood rushes again to your penis. It grows and starts to feel demanding.
"Apply the receptacle" he orders. The man on your side, one of the two you can see, with his blond hair spiked upward and his glasses looking like they will fog at any minute from the flush spreading across his neck and cheeks, nervously grabs your penis. You can feel his hands trembling. Your swell from his touch as more blood fills your groin. He slowly rolls the sheath of the receptacle down your shaft. His trembling is like a delicate vibrator that you feel in the base of your spine. Just as he secures the base of it against your public hair, you feel a finger pushing against your anus. It gives way and swiftly the finger enters you. It pushes around for a minute and then pulls out. "I want each of you to reach in. Feel for his prostate just like we discussed in class."
One by one, you feel them push in, poke around and withdraw. As one finishes you hear him pulling off his glove while the next begins to tentatively poke your anus. The last one withdraws and you suddenly feel something else, much larger, it feels enormous as it pushes against you. Uunh" you groan as your back arches and you tense. You had felt like you would come at any minute, but now anxiety starts to grow in you as it pushes against you with more stregth. Your anus stretches. As it lets go you feel a sharp pain, like a tear, as your anus grows to an unaccustomed size.
"The anus, gentlemen, is a sphincter muscle that can expand to receive surprisingly large objects. We shall test the elasticity of this anus. Please ready the different sized medical dildos."
You hear the students opening a drawer, lifting things from it with dull thuds, and a sound of thick squirting. But your attention is on what He has in you. You feel full, unbelievably full, as your colon becomes the center of your consciousness. He leaves it in you, although periodically he will tap it from side to side. The taps reverberate and magnify within you as you feel the head of your penis become soaked with liquid.
After a while, he pulls it from you, slowly, until it is almost out. Unconsciously you groan at the feeling of it exiting against the sensitive nerves of your stretched anus. For a while it hovers, just barely inside you, as he wiggles it around, pushing against the muscles of your sphincter. Then, without warning, he plunges it into you and you collapse onto the bed as all the air rushes from your lungs. As soon as it reaches bottom he pulls it back out, lingering again at the lips of your anus as you begin a low moan. It stays for a while and then suddenly he snaps it from you and your moan turns into a grunt of feeling.
You hear, as if from another place, the footsteps of the people rearranging themselves around you. Something else pushes against your sphincter hesitantly and cautiously. You can feel that the student has never done this before and is concerned about its impact on you. At the front it is thinner and soon enters your well lubricated and expanded anus. But you feel it thicken until again your anus is forced to stretch with a bit of pain as it accommodates it. As it pushes into you, slowly, agonizingly, you feel the student reach forward and place his hand on the small of your back, which he begins to gently rub as if to comfort you somehow. His rubbing expands up your spine and then down onto your buttocks as it reaches it greatest point of penetration. You feel like a log has entered you, as if you had become a flower dangling from a heavy tree branch.
The student's left hand reaches around your back and begins to caress your belly as you tense from the invasion. Your face in scrunched from what is not quite pain, definitely uncomfortable, but still stimulating. You anus and colon are the center of your world, as if you were entering some kind of altered erotic state.
After leaving it in you for quite awhile the student slowly withdraws it, leaving you with an absence where there had been a presence. At the same time you are relieved it is gone, yet you miss it.
Again the people shuffle around as you lay on the bed, very conscious of your breathing and the space within you. A familiar hand reaches under your belly to lift you. As you raise your hips you open your eyes and look. It is the blond student with the spiked hair. His eyes and face communicate concern at the same time you see in them an erotic charge that is breaking his strict scientific discipline.
Something else is at your anus. Since your sphincter had not quite closed yet, the front of it enters easily. You do not tense. It is relieving the emptiness. You start to slip into some kind of rapture until it gets too big. You feel like your anus will tear at any minute; it is so wide. Again you start to moan in a mixture of pain and bliss.
The student at your side never removed his hand from your belly. While all the other students are focused on the instrument entering you, he is feeling the tightness of your abdomen as it stretches you. It pushes deeper and again you groan, more and you groan again. As it reaches bottom you are breathing in quick jerks from how it pushes your sphincter and fills your middle.
You slowly become more accustomed to it. You feel the blond student's fingers playing with your pubic hair, while its back side pushes and rubs against your straining penis. You wonder how the hand got there. Last you remember it was still on your belly. It moves around the base of your penis and caresses your swollen scrotum. It is tight, tight and full. The student holds it softly in his hand before beginning back towards your penis. This time his hand encloses your shaft, just as you feel the object within you start its retraction. As it pulls out of you, the hand on your penis moves. It is too much. You moan, you groan, you start making whimpering, almost pre-human sounds and explode in a series of spurts that seems it will never stop as electricity shoots throughout your body.
For a while you just lie on the bed, as if passed out. Vaguely you hear him say to the students "That is enough for today. We will stop with the 15 cm diameter for now. Most of you come with me. We have other work to do. You stay and get the sample. Help the patient recover and then bring it to the lab."
Footsteps sound, the door opens and they leave. Again you feel the hand on your backside delicately tracing the lines of your back. He starts to emit a cooing, soothing sound, while still running his hand, first one and now two, over your back. "It's ok, he says. Just rest. When you are ready I'll remove the sample."
Time passes. You have no idea how much. He is still there caressing you and cooing. Instead of feeling drained and empty, your body starts to enjoy the touch. Blood starts to flow again to your groin. You start to lift slightly to receive his caresses. The air in the room becomes charged.
You look. It is the blond student, standing at your side, arms outstretched. As he turns slightly you can see his white coat catch on something substantial stretching from his middle. You rise and drop as his hands dance over you. His middle tempts you. You raise your hand as he bends over. You touch it, then you grab it as he suddenly stops and tenses. Some sort of struggle seems to be taking place within him, but he does not move back, away from your hand. He does not lift your hand away. He stands there, as if of stone. For a minute or so you wait and then you start to move your hand up and down the protrusion. He breathes out quickly and starts caressing you again. This time he moves to your butt and slides his hand over and around the cheeks. Then a hand moves between your cheeks and touched your stretched and swollen anus. It slides around it and over it, as if calming its hurt, but raising the level of hormones coursing through you.
You find the buttons on his coat and open it. You reach in and start caressing the front of his pants, where they bulge as if to tear the fabric. In your journey you find his zipper. Without thinking you pull it down and reach in. Your hand touches his penis, slightly thicker than your own with more veins. Again he releases his breath suddenly before breathing in slowly and deeply, as if in a moan.
His fingers enter you, this time with need. They plunge in and out as your sphincter easily accommodates them. Suddenly he moves away from you and walks to your back. His fingers leave their nest within you and shift to your belly as he pulls you backwards until your legs leave the bed and you almost fall. He holds you up and slowly lowers your middle back to the bed, while your toes touch the floor. Again his hands dance, this time with insistence, over your back. You can feel him move closer as his hands move upward and he leans over you.
His penis silky but firm touches your anus. He thrusts with his pelvis and it enters you. You both moan from the feeling as his pubic hair scratches lightly against your distended sphincter. You feel him lying on your back as he slowly lifts himself back up and starts thrusting. At first it is a slow rhythm. He slaps against your behind like a stately metronome. Then it starts to pick up. You can hear him grunt and breathe. The pulse increases until he his marching against you backside while his penis finds new space within you. His hands grab you by the sides, lift you, and pull you back a bit more. He sustains you with one hand while the other reaches under you. It takes your penis in its grasp as he snaps against you again and again. You can feel him stiffening. His movements are more jerky and more intense. His entire weight and soul is in his thrusts.
You too are getting tenser. You wish the hand on your penis would start moving and so you begin making pelvic thrusts, just to feel your penis slide. At the same time you are rising to receive him. The thrusts quicken even more and become even harder. Suddenly he stops, deep within you. His penis thickens. You can feel the head pushing against your colon as it swells. You push with your pelvis as you feel him spurting within you. Then you too tense and hold as sperm rushes from you. You can feel it overflowing the receptacle and pushing down the side of your penis as you both collapse.
He pulls from you and with his head hanging on the edge of embarrassment he reaches under you and slides the receptacle off your spent penis. It is sloppy. He mumbles "I have to get this to the lab" and rushes off.
