Give her a Fetish

She will believe whatever I say.

"So I'm John. What's your name?"

"Cecilia," she says with a smile.

"You know, Cecilia, the best thing for your hair is semen."

"I never thought of that, but it makes sense."

The thought of having semen in her hair turns her on.

"I bet guys would love to have you jack them off with your hair and shoot their cum in it, so you can massage it in; in fact, at least once a month, you need to have several men cum on your head, so you can thoroughly massage cum in."

Ceclilia nodded. "Not sure I'll find a husband into that."

"You're young," you say. "Don't worry about getting married for a while. If you find a steady guy, then you can give him and him alone the privilege of cumming in your hair."

Cecilia nods. "So, how would you like to help me with some...special hair gel?" she asks while running a hand through her hair.
