your older sister has always been considered “wired”, there non-binary, pan, and awkward, they are also a therian but to scared to tell you, or anyone, so they do quads when your not home, they also record them doing quads, and post them on tik tok, one day you went out and came home to them doing quads, they saw you and quickly got up and ran to another room, mom and dad weren’t home from work yet ether, but there never home anyway
