You seem a little intimidated. Instead of the normal thoughts of pleasure that should be raking your mind, you wonder how much her services are going to cost. Nothing this good comes at a good- your thoughts are interrupted. She pushes you into a chair and it nearly falls back before you catch your balance.
"Just sit back like a good boy." She says in a hushed voice as she glides her fingers through your hair like she'd done so thousands of times. She sits down on your lap and wraps her lips around your neck and kisses it sensually. She then clasps your hair and sniffs behind your ear, letting out a soft moan. You can feel her heat wash over you.
"Well... at least she enjoys her job." you think quietly to yourself. She bites down, tugging at your neck now. The pain is excruciating, and it forces you to struggle a little underneath her. She lets go and leans back, letting the hood fall from her for the first time. Her hair is deep brown and rests just above her shoulders, and she has soft, clean-cut features, and her eyes are a piercing bright blue. She gives you a sheepish smile, then laughs a little. When she opens her mouth you see that her teeth are a bit abnormal. She licks them seductively.
"Go ahead... resist." She says aggressively. "You still won't stop me." She slides a hand down your chest, then up again using the opposite side of her hand. She arches her back and thrusts her chest forward, and it bursts out with a sickening crack. She holds her breath for a moment, and lets out a moan with her next exhale. Her chest was... expanding?
