Boob attachment

From Voyeurweb's Wiki

Boob attachments are funny things which girls sometimes attach to their tits or in particular their nipples. It is unclear what they gain from this and it seems to be some kind of old tradition like dancing in the rain or scratching balls. It also not clear at all whether girls try to hide their nipples when attaching stuff to their nipples or whether they would like to draw attention to their nipples.
