Before Kristi could even think, she spotted someone that she knew from her school. She was pretty sure that his name was Erik. He was pretty average looking towards muscularity and height, only being about 5'8", but how he looked was a different story.

Kristi just giggled at the sight of the teen hunk.
She decided to....
