BDSM term developed by #1 US/International Best-Selling Author, Breanna Hayse and is used to describe a Twilight BDSM lifestyle. The Twilighter is a masochist/submissive whose age-play dynamic emerges with the onset of edge-play/heavy sadomasochism. She/he tends to be aroused by contrasts of pain/pleasure interspersed with tenderness and nurturing. While she will often used addresses associated with the age-play dynamic (Papa, Daddy, etc), these are used to maintain her vulnerability and headspace. BDSM age-play does not involve minors not does it condone pedophilia or domestic violence/abuse.
"Many look to fall into a place of bliss during a session and become calm and quiet. A Twilighter will fight and protest like a child until she's exhausted, and then might sulk and get weepy. She's happiest when she feels pain and throws a tantrum."
