Your thoughts work about in circles as you think back to the way life treated you. The pony which is you now, aches from the previous day's working, yet the feeling of it's strength comforts your wondering mind too.
The hord of resposibilities which once pressed down upon you are gone. Now life is very simple as the people who govern over your life expect only simple things from you. Your animal body is perfect for the massive strength it can excert in pulling and running. As you accept this form even more the act of mating with mares will also come more natural and with not envoke any moralistic thoughts.
As you lay in filth cover straw bedding and roll your head to lay within inches of a pile of dry mare manure you are calm and restful.
Life is easy as a pony, you are taking quite a liking to this relaxed atmosphere. Even the crack of the Coachman's wip is only a passing worry and not one which lasts to be thought or made as a threat.
A mare wanders close her intentions are those of sensual pleasures and she wants you to do your little trick again. As you rise to the occasion and one erection rises too the passing thought of wasting time and life being a stallion and pony offers not a care.
