A story about twin fox spirits having lots of sex

One day, Tsukine tried to invite her brother, Netsuki, to play, but he coldly turned her down. Desperate for his attention, Tsukine used her transformation magic to turn him into a helpless version of himself!
As she doted on her now-small and powerless brother, her mischievous side—and her lust—completely boiled over. Tsukine begins to "pamper" every inch of her brother's fragile body, and there's nowhere for him to run...!
