Medical Sample

You open the door and step into the medical themed booth.

Inside you find that the booth opens up into a small sterile room with a cot to the side and a pair of holes in the far wall; one at dick level and another at arm level. A latex gloved hand reaches out and beckons you forward. You hear a voice saying "Ah, a new subject. Come forward and we can begin the test. Please insert your penis in here."

You drop your pants and hesitantly slip your cock through the hole. "Good specimen here." You feel the hand analytically examine your penis. "Good size, good girth, no bends. A very good specimen. Please insert your arm into the slot and we can begin the test." You slip your arm in and feel them rub an **** swab against your inner elbow. A moment later you feel the sting of a hypodermic needle. Before you can process it, you feel another pair of needles insert into your cock and testicles.

The instant they remove the needles, you reel back in agony. You were hoping to *give* the sample, not received it in the form of a needle in your BALLS. The voice tells you to sit on the cot so they can monitor the effects. You do so and feel a warmth build in your body. The sensation is deeply arousing and soon you begin to stroke your sore cock. As you do so, you feel it grow in your hand and become girthier. Soon you can't even close your hand around it anymore. You can't imagine it ever fitting into someone at this size. You keep stroking it and notice that your urethra is expanding. The warm hazy feeling compels you to do something you never would before and you insert a finger inside.

The sensation causes a jolt of pleasure to shoot through you. You rub your finger deep inside your slimy urethra. It feels like your cock is inside out, every sensation inside triple that on the outside. You start to pump your finger in and out like a girl shlicking herself for the first time. It feels so good. You need more. Soon you have all four fingers shoved knuckle deep inside your slutty pee hole, **** for relief.

You hear a noise and lazily turn your head to the side, noticing that the wall has opened like a door. A man steps in naked, his long cock swinging side to side. You don't need any prompting to swing around and hold your cock up in anticipation. Your pee hole looks like a pussy at this point, dripping precum like a leaky faucet. He grins and his cock throbs in anticipation. The sensation of him shoving it in is orgasmic. You can feel his fat cock hit near the base of your own. When he finally cums, you can feel pooling and dripping in your swollen balls.

The door opens again and another man steps in to take his place. You welcome him like a bitch in heat. They are the first in a long line of men, human or not, that enter to fuck your cock like a pussy. You lose yourself in the pleasure after a minotaur man shoves his massive ox cock in you. The last thought you have before melting into bliss is how it's feels for his fat balls to slap against your own.
