Poor choice of plants

Diane let out an elongated yawn, she must have been walking for hours now! The sun was long past midday and was actually beginning to set. She took some comfort in the fact that she was still heading in the right direction. Soon enough it would be dark out, and Diane was contemplating whether or not she should just find somewhere to rest in the forest until sunlight the next day. After all, it wasn't like the others were going to leave without her. Regardless, one thing kept bugging Diane, ever since putting these leaves over her privates, she could't help but feel this tingling feeling over her body, but she just presumed that was from the river earlier and her current state of undress. Diane finally decided to sit down for a bit and regain her energy, she had been hiking bare foot in the woods for hours, and her feet deserved some rest. Suddenly, the tingling feeling from earlier started to intensify to the point of being rash like, and Diane began to scratch at the affected areas, particularly her privates. In spite of this, no matter how much Diane was scratching, the rash only seemed to get worse, now it was burning! Diane frantically ran her fingernails all across her body in a vain attempt to alleviate the itching, but to no avail. Several minutes went on, and Diane found herself sprawled out on the grass, rubbing and scratching her front side, while rubbing her backside against the grass. Soon, every scratch Diane could not stop herself from making gave way from vague grunting to involuntary moaning. Diane was desperately trying to think about what was causing this heinous rash, before realizing that it had to be the leaves she slapped onto her breasts and privates, it had to be some kind of poison ivy. Diane scrambled back on her feet and charged back into the river, tearing the leaves of her body all the while. Just as Diane was several feet away from the river, she leaped forward and dived headfirst into its waters. Upon submersion, Diane could feel the burning sting of the poison ivy starting to wash away, and before long, it was completely gone. Diane then emerged, letting out a sigh of relief once she did, before swimming and crawling back onto the riverbank. Glad that her little ordeal was over, Diane focused back on her bigger one, and kept pressing on towards town.
