"1st time alone with a man?"

Lizzy blushes flame red. "Well,...yes.."

"Relax, I'm housebroken..except for a tendency to eat anybody within reach, and that's pretty normal around here."

Lizzy doesn't seem to know whether to laugh or frown at this, so you continue... "I'm Rick, Rick Copper. They said you were called Lizzy. Do you want me to use your full name?"

"..No...no, just Lizzy.."

Bad. That probably means her family disowned her and forbad her using her family name when they discovered she was vore. Some people are so intolerant. Just because vores are ravonous beasts eager to eat anybody in reach at any time, is that any reason to discriminate against us? Don't those people believe in diversity?
Well, you had best discuss that with her another time. The subject is likely too painful to get her in the mood you want. So change the subject.
"I know an easy way to get you relaxed. Just sit down on your bed and I'll give you a relaxing back rub..."

Lizzy seems skeptical, but not negative.
