After about ten minutes or so of the cowtaur playing stairmaster on your nuts, she finally relents. "Whew, what a workout! WOuldnt you say?" You look up at the cowtaur, tears of pain streaming down your face. "Auhhh, poor little bull, I know just the thing!" She walks around the corner, and back into the same room where she keeps her collection of serum. You inspect your balls... even though you just cummed about 10 gallons worth of sperm, they are still the size of watermelons.
You notice that they are pulsing idly inbetween your legs while the milking machine does it's work. "here I aaam" The cowtaur calls, as she enters the room, "This is a new formula! It should increase your production about 20 fold. I havent tested it yet" She states very seriously.... "You should be honored, your the first person ive considered testing this on!" She pulls out a gigantic syringe, completly filled with more of the milky serum that she injected into your balls. Before you can move to block her, she jabs the needle deep into the middle of your chest, and pumps in the liquid fire. Once again, you find yourself spiraling deep into the oblivion of uncousiousness.
When you awaken, the first thing you notice, is that your testicles are larger, if thats possible. You try to sit up.. "OUCH!" you yelp, your chest is very very sore, and there are six suspicious bulges on your chest, which you can see almost visably growing. You rip your shirt off to get a better look. To your horror, you see that there are eight smaller bulges on each of the six larger bulges that are swelling into existance all over your chest.
"Ahhhh, awake already? perhaps I didnt use enough serum!" bessie calls from in the other room. "What the heck did you do to me this time?" You call. Bessie pokes her head out from her shack, "I told you, I am increasing your production rate!" she calls... "Ahhh, good, you seeem to be coming along nicely... you should be entering stage two shortly!" As if on cue, the swelling sensation in your chest increases in intensity, as all six of the growths begin to swell even faster. "Oh my GOD, those are breasts, arent they?" You call into the other room. "not quite breasts" She chuckles, "Udders! Special ones at that." you look down, and are surprised that she is right... all six udders have reached approximately the size that they would be for a normal cow, however your swelling nipples seem to be growing strangely. you grasp one, only to be greeted by a very pleasurable sensation... As they continue to develop, you realize that they are not ordinary nipples. "My god... are all these things penises?" you mutter.... as if to answer you, the 48 cocks on your massive udders finish taking shape. you start as a large hoof comes to rest on your shoulder... "Ahh, about to enter stage four I see, you should be done soon! I will be right back. Suddenly, smaller bulges begin to develop at the base of every one of your new cocks, your growing testicles on your already huge udders! What next? Bessie rounds the corner again with another milking machine, and begins hooking them up to your new penises... what next?
