Steal the swap gem from him.

As he pushes you forward roughly you sag backwards into him, falling. Your back presses into his chest as he catches you. Hands about your waist, your ass is at his crotch. He holds you for a moment, a hand dipping lower to brush your mons. You sigh in pleasure, almost distracted from your task.

With your shady past it’s no surprise that you’re an accomplished thief and pick pocket. It’s all about diverting the marks attention. You’ve never had a better diversion than your current naked body. Unknown to your gang mate, your hands slip nimbly into his pocket. You grip the gem and, wiggling your ass into his crotch with perhaps a little too much enthusiasm, you pull your prize free and palm it as he pushes you forward.

Success. You have it. You have it… but what are you going to do with it?
