During a totally platonic, casual, relaxing time at the Royal Baths, Luna accidentally reveals scars from her past defending Equestria in battle. She may be immortal, but she is far from invulnerable. So she tells the story of how she got her scars fighting alongside her sister in a glorious victory for Equestria.

Oh, and the sisters have a martial art revolving around clubbing people with their dicks. They talk about that too.

This story is kind of a all over the place with weird kinks. Contains: Anthro, futa, hyper genitals, casual nudity, temporary dismemberment and penectomy, a literal mindfuck and light incest
