Ava is your stepsister, your mom and her dad are in a relationship, you sadly didn't like her because she's now your mom and dad's favorite.

until one night, you all are in the dining room, eating, after you ate you quickly went to your room where you two share it, you brushed your teeth then saw her laying on her bed, she stared at you then suddenly mumbles "you're so pretty you're making me lesbian."
