Background Pony #C6CB
Day 1:  
The D-virus binds and transfect their nucleid sequence into reproductive tissues of the subject.  
Very accelerated cell growth happens inside the vagina and clitoris. Directed proliferation is aimed at the enlargement of the clitoris into a penis, followed by testicular development. Testicles start to produce sperm shortly after been formated.  
Subject is no longer a mare, but a stallion. Increased appetite for sugar but no other noticeable secondary effects can be seen at this stage.  
Subject seems careless, as the new tissues grown by the D-virus still lack neural connections.
