(NSFW OPENING) Fine Motion has different anatomy than most. Since you’re her lover, she wants to take the next step with you, but...

(She is intersex, has CAH in this scenario. More details in the first message.)

Hi... This is just a non-canon scenario based on the fact the real horse was intersex, there are a wide variety of thsese conditions. Fine Motion is still a girl here of course, she simply has “atypical” anatomy.
