You can see now why Marisa had taken off your pants before your legs had changed. The long crimson and black tail would've completely torn them apart, and likely hurt you in the process. You wonder where Marisa could've gone. Did she really just abandon you in this cold office like this? That f- A soft cry of pain reverberates through your body, and you realize you were instinctively using your tail to squeeze a soft source of warmth beneath it. While it does feel good having your tail wrapped around the warmth, you have a pretty good idea of what it is. You don't have much practice using a long snake tail in place of legs, but you do your best to loosen your hold and slide off of it.
As soon as she can, Marisa climbs out from under you in a hurry, gasping for breath. "Finally!" she exhales, leaning against a wall well away from you. Once she's caught her breath, she looks at you angrily, but you can taste fear more than rage. Wait, taste? You hadn't even realized it at the time, but you had flicked your tongue out and been able to... taste her emotions in the air? You run your tongue around your mouth as you think about it, soon discovering you also have two long fangs. "You couldn't have woken up any sooner?" she shouts, bringing you out of your thoughts.
"What are you yelling at me for?" You hiss at her defensively, showing your fangs. As soon as you realize what you're doing, though, you cover your mouth, face going red in embarrassment. Still, you can't help feeling a little satisfied at the way she looks, losing a little of her edge.
"Just... Just calm down, David. I don't know what happened, but we'll get this all sorted out." She stands up slowly, eyes never leaving you. You lower your hand to get another taste of the air, finding it even fuller of whatever smell is telling you she's scared. "I know someone who has more experience with nagas. They might be able to help. It's late, though, so they probably won't be able to arrive until tomorrow. I need you to stay here for the night, okay?"
As she opens the door out of the office, there's a rush of air, bringing with it the musty scent of the store room, but also tastes of the outside. You don't want to be cooped up in some tiny room all night, especially not at the request of this witch that turned you into this snake-girl freak. On the other hand, without Marisa's help, you'll be stuck like this forever. You don't have much time to decide, but in the end...
