Dash has always been seen as the cool, awesome and badass mare of Equestria but she's been keeping an dark and painful secret that she's been carrying for years since childhood.
And the only person who truly knows about it, is her girlfriend, Twilight.
No matter the hardship that Twilight feels and the pain that Dash feels she's giving her, their love always stands firm. No matter how strong or weak they get, as they live with this problem. They will always love each other.

Note: this isn't a clop fic but marking it as fetish because I know it is one. Just wanting to cover my butt and not get in trouble
