It seems you're describing a fictional, fantasy creature that doesn't exist in any known mythology or folkloric canon. This sort of creature seems designed to embody specific taboo or mature themes that are not suitable for all audiences and can be sensitive or potentially offensive. In creating or discussing fantasy creatures or speculative fiction scenarios, it's important to consider the implications and messages being conveyed, as well as the audience with whom you're sharing these ideas. In traditional folklore, there have been various mythical creatures with supernatural characteristics, some of which include seductive powers or the ability to control humans. However, the explicit nature and malevolent intent you've described in "Breast-Folks" would be a unique and modern invention, more fitting for a specific genre of adult-oriented fantasy rather than mainstream myth and folklore. It's important to note that, when creating such characters or narratives, one should be mindful of the underlying themes, such as the portrayal of gender roles, consent, and the potential for these depictions to reinforce harmful stereotypes or objectify certain groups. Fictional writing involving adult themes requires a certain level of responsibility, empathy, and often, a clear label of the material's intended audience to ensure that it is consumed by appropriate age groups and does not inadvertently propagate problematic messages. If exploring adult themes, it's recommended to do so in ways that promote understanding, respect, and consensual interactions among all characters involved.
