Make her horny first

From Torg Adventure

You put explicit drawings of various explicit sex acts on the papers she's filing. Each one she sees she imagines herself being a participant in that activity. You make her imaginings be multi-sensual: she can see, hear, feel, smell, and taste in her fantasy. You hear a series of moans and whimpers coming from the office. The noises get louder with each picture the principal sees.
