Brussels has been struck by some unexpected pornographic graffiti, at the hands of an anonymous erotic street artist.

Penises, a vulva, a snapshot of penetration and an artistic representation of an anus have all been daubed across buildings in Saint-Gilles, a town in the Brussels region. A masturbating woman image also appeared in Place Stephanie, another nearby neighbourhood.

They’ve been popping up since mid-September, much to the amusement and horror in equal parts of local residents. Brussels MP Vincent Henderick was reported by IB Times to have called the art ‘inappropriate’ in a local parliament meeting, and the local mayor and authorities, according to the Daily Dot, have announced they will be removed.
