She watches him

Hiding among the clothes, Louise stares at Eric's bare legs, and up to his tight black boxer shorts. There's a fairly impressive bulge in the front of them, and Louise bites her lip, as she stares.

You throw some erotic thoughts into Louise's mind as she stares, knowing that she's had a crush on him for a while, and you watch as she slides one hand down between her legs, rubbing herself for a moment through her skirt.
