Had an idea that adds to the idea that Yveltal loves chocolate of a possible final food stage near the end of the journey and its called "DEATH BY CHOCOLATE". It starts with a pure darkest solid chocolate core and adds layer after layer of different chocolates to it almost like a planet. Ex: pickle chocolate, Mexican chocolate, strawberry chocolate, fudge chocolate, liquid chocolate, chocolate gingerbread and chocolate caramel. The last layer will be chocolate cotton candy to simulate clouds with chocolate stars for space. This would reach nearly the size of a small car with hundreds of layers each different and no repeats and when Yveltal sees this she drops to her knees in happiness and mutters "chocolate planet" before starting to eat it and it will take a week to finish it.
Also had an idea that when Yveltal uses her mouth for a blowjob either the MC or her would put chocolate syrup on his dick so she will give a sensual blowjob and will think the cum she gets inflated with to her stomach is white chocolate and lick up every drop.
