You can see the zebras large cunt. It is pink and wet, and you realise that you have always found horses very attractive. A zebra is an equine as well, so why wouldn't you have the same feelings?
"Go on then, human. Take me." the zebra says, knowing your fantasies.
You hurriedly undo your trousers, glancing nervously around. No-one else is here. No-one will know.
You are stark naked, and now faced with a problem. Due to the zebras size, its ass, including the vagina, are at head height.
"Err, I can't reach." you say simply.
