For some reason the first few that come to mind are one-shots:
A Blackened Mist and In Anger and Affection both by Mana Mihara;
Do You Remember Love by DigiFruit - a little unconventional in your criteria but Naruto is definitely older;
Oh now some more are coming to me:
In Your Heart by Catsi563 - this is still ongoing and the third story in a series which I recommend;
Rain or Shine by Ciardha - lovely story profiling Naruto's growth to Hokage and Sakura's involvement;
Training for the Job by Desaix - ongoing (hopefully) and the story spans several years in Naruto's life;
Those are off the top of my head. Hopefully, these stories are new to you. If you haven't already, I would recommend you check out the first page of this thread and the NaruSaku Fic Recommendations thread.
