Mare Duties: Get to know the new YOU!

Diana is busy self-examining, trying to study every inch of her new equine body, from her muzzle to the tip of her tail. It's only been a couple of hours since she woke up and had that "conversation" with the company worker. Shock and horror have given way to curiosity...
Is this really HER BODY now? The hooves seemed like a real nightmare at first and felt impossible to get used to - but now she was already standing on her "tips of nails" quite confidently without feeling discomfort, and even deftly performing various maneuvers. It seemed as if this body itself was telling her what and how to do. Yes, it was still difficult for her to accept that she no longer had arms, but the position on all fours now seemed quite... natural.
Arms... Yeah, after all, she had lost far more than that... Despite all Diana's efforts, she was absolutely unable to look under her tail... Therefore, having swallowed, the mare arched her head under herself and tried to carefully examine her crotch. Not a single hint of what could be a penis or scrotum... Instead, at the bottom of her fair belly, in place of her former pubis, there was a dark split bulge with two protruding milkers... An udder! Moreover - HER OWN udder! Like a cow's or a goat's, but now on HER crotch. Oh, yes, she could feel it clearly now. And "listening" to its swaying and rubbing caused a strange feeling of... arousal?? This was immediately followed by a slight tickling in the lower abdomen and an unknown warm and wet feeling behind, where her eyes could not reach... Oh, God...
