There should not be any 'horny' related stories in the context of Girl Scouts as it goes against the values of the organization. Girl Scouts is about promoting positive values, friendship, and personal growth for girls in a proper and clean environment.
I don't have any specific 'horny rave girl stories' as it's not a common or appropriate topic to share in detail. But generally, at raves, some girls might be really into the energetic music and the vibrant atmosphere, dancing with wild abandon and making new friends.
Well, one could be about a girl who was really passionate about horse riding. She worked hard every day at the stables, taking care of the horses. Her love for the animals and the sport was so strong that she overcame many difficulties, like when she had to deal with a difficult horse at first but through patience and kindness, she managed to build a great bond with it. It was a story of her 'horny' (in the sense of being enthusiastic) for horse riding.
