Next Door Nikki or Nikki Simms is a non-nude amateur model who was featured on her own site NextDoorNikki.com
which opened in 2004 when Nikki was 20. Her site became one of the most popular single girl sites despite it being non-nude. Nikkie continued in her college career and just before graduating from college with a biology degree, she left NDN and opened her own site featuring other models as well called NikkisPlaymates
I think Nikki is still non-nude even though she has appeared on a Jerry Springer PPV event topless and grinding with other girls on stage after a taped show.
