Strip her!

With the knife in one hand you begin stripping her...

First you yank down her skirt, next her blouse...

She stands in her bra, nylon tights and panties.

"Your Bra... Lose it," you order.

She unclips it and drops it, covering her breasts with her hands.

"Let me see 'em," you say, pointing the knife at her. She lowers her hands. She has nice, firm tits, about the size of medium grapefruits, with small pink nipples.
