She looks at you and says:
"Hey babe! Thanks for coming along. I hope this isn't going to be too uncomfortable for you, being teased in public...
You are immediately scared. She didn't say anything about teasing you in public before! But she continues:
"But I thought it would help if I tease you, since I've practiced with you..."
You are scared, but very turned on. You can't refuse her, so you say that will be okay.
