Twilight Sparkle is a big mare now. At least, that's how she sees herself. To Shining Armour, she's still his eternally adorable little sister, who he has a less-than-healthy fixation upon. Combined with a nasty little sister eroge habit, a masochistic wife, a sadistic employer, and a little sister on the verge of being stolen away some other stallion, his decision-making capacity might not be at peak levels. Follow Twilight's adventures in the confusing world of dating, as her creepy possessive complete bucking batshit over-protective older brother tries to keep her single at all costs.
