No, nipple tickle stories are not common. It's a rather specific and not often - talked - about topic. Most people don't usually have stories centered around this specific type of tickling as it's a more private or personal area.
Nipple tickle stories are far from common. People tend to focus on more typical tickling scenarios like tickling someone's sides to make them laugh. The nipple area is a more sensitive and private part of the body, so stories related to tickling there are not as prevalent as other more general tickling stories. There may be the occasional innocent story among very close friends or family members, but overall, it's not a common type of story.
