The doctor walks up beside you and sticks you with a large syringe. you neigh and buck wildly as you feel your muscles twitch. you begin to feel searing pain in your muscles and fall to the floor and all goes black. when you wake up your human again and back on the examination table. your strapped down and covered with a sheet. the lab tech has her lab coat back on and smiles with a wink when she notices you have awakened. you scan the room for the doctor and notice a lump in the sheet over your crotch. you can feel something moving around down there. then the sheet lifts up and the doctor emerges. "another successful mutation" he says to the lab tech who smiles and walks over to stand beside him admiring his work. the sheet is bunched up so you cant see what they are looking at. "w-whats going on? what did you do to me?" you ask hesitantly. "lets test it for response" the doctor says to the lab tech who is obviously more than willing. you watch her move in and begin licking and tickling your cock. you can feel yourself starting to get hard. the doctor scribbles onto his notepad. you feel something tickling your ankle and realize its your cock. "holy shit!" you exclaim. the nurse pokes her head up and smiles then goes back to work kissing and kneading your long serpentine like cock. the nurse stands up and turns around to face the doctor. the doctor smiles and whispers something to her. this frustrates you and you struggle to reach her. then you notice that your cock is reaching for her. the doctor and nurse are talking back and forth not taking any notice. you start focusing your attention on where you want your cock to go and it moves and reaches like just another ordinary limb. you reach towards the lab tech and poke her ass with no trouble. the doctor was in mid sentence when this happens and the lab tech tried to stifle a giggle. the doctor looked at her strangely for a second and continued on and on about elasticity and a bunch of other scientific jargin. you carefully reach under the lab tech's lab coat and slide up her thigh.
