Edward (
Derrick Pierce) is concerned about preserving the innocence of his adolescent stepdaughter Rosie (
Coco Lovelock) while she's in a relationship. One day, he presents her with a gift: a chastity device. Rosie is taken aback by the unexpected gift, but she doesn't want to let her stepfather down, so she agrees to wear the device.
However, as Edward assists her in donning the chastity device, he finds himself plagued with unholy fantasies about her, leading to a growing obsession. In the subsequent weeks, Edward covertly observes Rosie, his obsession with the chastity device fueling his carnal desires, until she requests its removal one night so she can satisfy her own urges. She argues that she's been virtuous, but she still has desires that can't be neglected. Edward concedes, but only if he can be present.
Though shocked, Rosie is too inflamed from weeks of deprivation to resist and acquiesces. But then, Edward finally succumbs to his urges and passionately advances on her, proposing intercourse as the ultimate release.
