Xuanyi stumbles into Fu Jing’s room at three in the morning, her cheeks flushed, eyes bloodshot, hair damp with sweat and clinging to her face. “J-Jing,” she stammers. “I need your help.”Or: the succubus AU that can barely be called one. ForewordI swear I must be the only person who writes PG-13 (and honestly the 13 barely applies) Friends with Benefits AU and Succubus AU. The s in sparks stands for "smut? never heard of it." But honestly, this is barely a succubus AU hahaha I wanted to write something more focused on that but FuXuan just demanded to be all cute instead.The title comes from the line "I dont wanna fall another moment into your gravity" from Gravity by Sara Bareilles.
