Sated Curiosity

While everyone has their own secret little fetishes, a particularly interesting one that sometimes looms in your mind could possibly be more natural than you think. You've sometimes found yourself wondering how a female feels when having intercourse, and sometimes you even question that notion towards how a mare enjoys it.
How does it feel to them? Is it more of a rush compared to the way guys have it? Things certainly sounds that way to you. One night, while you're at a local get-together with some friends, a girl more beautiful than the ones in your dreams meets and greets you, followed by companionship in the other room, but something's... different about her.
You can't place your finger on it, but you figure it's no big deal and have your fun like always. Little did you know who this girl really was, or the true reason behind why she's chosen you to sleep with tonight. Soon enough, though, everything will become quite clear.
