Snapchat allows you to create custom stories just for your friends

Snapchat just rolled out custom stories, a new feature that allows you to share stories with friends of your choosing. The feature works just like other Snapchat stories, but disappears within 24 hours if no one in the group adds any updates. To make your own custom story, you tap the new “Create Story” icon in the top-right corner of the Stories screen. Once you select a name for your group, you can invite friends and even nearby Snapchat users.
