First time was with a mare

I had my first Zoo feelings at the age of ten, I really didn't realize they were
sexual until I was fourteen or so. The first stirring came while I was riding
bareback on a neighbors stallion. Laying there on his hot sweaty back, as the
powerful muscles of his body brunched and strained under me. I had never
experienced feelings or emotions like the ones that flared through my being. At
about the age of fifteen, my neighbor who was getting too old to look after
them. Hired me to look after the stallion Apache and a little gray mare named
Snowball. I was having trouble with my family by then, as I had already began to
realize my nature. So I spent a lot of time in the barn with Apache and
Snowball. When Snowball came in season, my neighbor ordered me to lock her in
the barn. Poor Apache wandered back an forth along the wall outside her stall,
frustrated and masturbating. Inside Snowball was flagging her tail and standing
ready. All the fantasy and things I had been thinking about for over a year
before that. Were suddenly very real and right in front of me! I was amazed and
enormously gratified when she excepted me! I realize now I loved her like a wife,
but at the time I was fooling myself into believing I just wanted sex. And yes
if you were wondering I did help Apache get off, with both my hands and mouth.
Two years later when a friend wanted to show me about bisex, I knew a lot more
then he thought!
