The Wild Sea Breeze (слэш)

"Iruka had been looking forward to this trip for months. Not long after they had met Gai mentioned needing volunteers to help walk beaches for cold-stunned sea turtles and Iruka had jumped on the opportunity. To his surprise, Naruto also was eager to join, despite the fact that it meant not only giving up his weekends (the only time either of them could actually volunteer) but walking beaches in nor’easters during freezing temperatures and violent winds at ungodly hours of the night."
Or a follow up to Seals and Shorebirds where Naruto and Iruka walk beaches for cold-stunned Sea Turtles and Kakashi tries to build a bond with Naruto.
