Hypnospank

Hypnospank, aka Shioki Geshuku is a flash game created by The Cynosure Collective in the mid 2000s, combining elements of mind control, spanking and age regression. The main protagonist is a woman in her late teens, unwittingly subjected to age regressive conditioning. Post-hypnotic commands reduce her to a childlike state, in which she loses all memory of her adult life, genuinely believing she's a young girl.

Scenario
Whenever Sheri and her boyfriend get into an argument, he places her into a fugue state and subjects her to a good, long spanking over his knee (something her juvenile persona finds utterly humiliating: No, Daddy, please no, not on the bare, not on the BARE). When the punishment is finished, he restores her normal personality, warning that the next time will be far worse. The memories of her ordeal - along with a hot, stinging bottom - leave her thoroughly chastened for the time being. Sheri has considered leaving him on several occasions, but his influence over her is so profound that she can barely leave the house without his permission. The one occasion she tried to sneak out led to the Mother of All Spankings and a week trapped in her juvenile persona.
