Interrogate her yourself.

My dear, please sit on the couch. I'd like to ask you some questions...That is, if you don't mind. If you do mind, I'll be involving the police.

She looks frightened to you. Like a deer caught in headlights. You get to thinking about headlights and look at her nicely shaped breasts. Seeing her nipples hard, straining against her skin tight top, makes you think about how hard your dick is getting.

She does what you say and sits on the couch. "Please, please, I swear I took nothing. If you let me go, I'll never come back," she is pleading with you now. Is she worried about you calling the police or are you frightening her? You think you should put her mind at ease.

"I am not considering calling the police at this point young lady. And I'm not going to hurt you in anyway. But I would really like some answers," you say sternly.

You stand there, looking at her sitting there, wondering what she looks like without any clothes on, if she is good at sucking cock, how it would feel to fuck her. You are silent for sometime before you begin to question her.
