Brothel

A brothel is a building or location where prostitution is carried out, usually in a group with paying customers to whom such services are rendered. Brothels do not appear in mainstream Smurfs media since they are mostly written for children.

Empath: The Luckiest Smurf stories
Brothels do appear in various places among both humans and non-humans in the EMPATH: The Luckiest Smurf story series. Tapper frowns upon the idea of having a brothel being established in the Smurf Village due to his belief that sex should be reserved for marriage as a blessing. Nevertheless, the Imaginarium is used for that particular purpose, although with holographic partners that the Smurfs could engage in their private activities with, and with certain restrictions to keep underage Smurfs from entering into those fantasy settings.
