Distract him with your body.

As you near the door, you start to peel off some clothes. You try to flash bits of you to get him worked up, and you hear appreciative noises from him as you go. By the time you reach the porch, you're topless and removing your bra, trying to keep his attention on you as you reach for the door. There's weapons all over the place inside, and you need to make sure that at least one escapes his notice. Preferably he won't see any, distracted by your chest.

You turn back to him, ostensibly to warn him that it's dark inside, but mainly to give him an eyeful that will leave him wanting more. You're shaking with the fear, but your mind is running a thousand miles an hour. His grin at your words shows that your distraction has had the desired effect. He's even lowered his gun slightly.

As the door creaks and you step inside, he follows a few paces behind. You start to lower your waistband, revealing the ass that Todd loves so much, gradually tossing chip after chip on the table in this highest possible stakes game. He seems to be fixated on you, but you're still a few steps away from where you need to be.

His steps behind you increase in pace. He's about to make a grab for you, you just know it.
