Hi, my name is Erica. I was named Eric, and I used to be a successful horse racer. I was a 21 year old man, at 5'9". I had dark brown hair, that went a little passed my ears. I was 240lbs and had no physical disabilities or any of the sort. My life had recently become very interesting in the last 2 months. I had gotten many wins, and met the love of my life at one of the races. She was a scientist, and seemed very interested in my job, mainly.. the ponies and horses I worked with. She seemed almost obsessed. After many dates and some raunchy fun in bed, I felt very close to her. One day, she told me as we lie in bed after sex, "I got a very special experiment I've been working on. Could I use you as a subject?" I was half asleep, but I agreed, and she reassured me that no harm would be done. The next day, I was lying on the sofa when she pricked me with a needle. She smiled, caressing a hand on my cheek, "The experiment will be very short." She was right, I awoke... but, I could not stand normally. I looked down to see large 34GG cup sized tits swaying beneath me, each with the nipples pierced. I whinnied loudly, in shock. The whinny added more surprise, and I tried to speak again, but only horse noises were emitted. Just then she entered, and smiled. "It was a success, Erica!" She praised, patting my romp. She attached a leash to the collar on my neck and reins on my head, leading me to a full length mirror. I looked in horror, at.. a bright pink ponygirl, with blue hooves, long blonde hair, large breasts, a blonde pony tail, facial makeup, and a blue saddle. I whinnied, as she began to pat my romp again, whistling a song. I seemed to calm down, and she brushed my hair. "You will get used to this, my love." She said, then cackled loudly.
