Horse Ride by SG
This three-part exhibitionism story follows the female narrator during her adventures on her uncle’s ranch. Being quite interested in self-bondage, she comes up with certain modifications to her riding-saddle to include some not-so-small plugs. With the plugs actually larger than she could lift herself off, even if she stood completely up in the saddle, she manages to create quite the difficult situation. Especially considering she lets her horse just wander around by itself, without her having any control over it.
