You then told her about the story and asked her why she see you special. "Yeah, I knew they others would think that I'm some creep that fucks little fillies, so I made up this story that you're some lost kid, but honestly, you aren't all that special to me. Though, I must have beaned you good, you were still knocked out when I rutted you."
You then feel a bit violated but go on to asked why when she woke up she was covered in some sticky white stuff. The mare's cheeks somewhat flushed at that. "Ehehe, yeah uh, I couldn't bring myself to filling your belly so I decided to unload on you. Though you have no idea how good it felt to be as pent up as I was."
Finally you asked if you could go. "Hey, that's up to you kid. You're free to leave whenever you want. I just needed a good ol' release and thanks to you, I finally got it."
