Amber Summer is trying to give back to the community, so she has volunteered as a Big Sister. She has been assigned to a newly blended family with Kimmy Kimm,Spikey Dee, who are trying to navigate their stepsibling relationship. Amber is convinced that the stepsiblings are fucking, which she finds super hot, especially since she's into Kimmy. As she's trying to figure it out, she tolerates the stepsibs ordering her around more like a maid than a Big Sister.
