Imagined it pretty much like this. Artist: nsilverdraws.
A quite talented person :)
(and yes, i'm still trying to put the ending together, yet have to deal with RL. . . )

booru.org -nsilverdraws
Contains some very soft 'nsfw', which are TAGGED AS SUCH and have to be opened manual... - and a lot fine safe art!

Those were created with Paint.net and NovelAI 1.3 (a rather wonderful tool) for horses ♥
