I believe it's a sexual fetish
For those who misunderstand what "horse-play" is supposed to mean.

[Edit] Like this one.

Not really NSFW as it's only words, but you wouldn't want anyone to read it over your shoulder and there's a good chance that it will hit the company firewall.

Since you're not going to click it
I'll quote some of the introduction- that should give you an idea of what it's all about.

"In addition, this magazine is a forum for men and women who are linked together by the desire to use human ponies as an expression of erotic pleasure. Having one partner assume the role of a human pony while the other partner assumes the role of trainer, rider or handler and controls the role playing scenario of this highly erotic activity, can be a very exciting part of this fetish."

See- I was right.
