Be nice to her. Tell her how sexy she looks. If you get a chance, feel her boobs n butt "by accident" If she says anything, apologize. Let her catch you jerkin off. She will ask what you do and you tell her it makes you feel good and she can feel good too. Tell her put hand inside her clothes and rub her tang. She will like so much then you can say if you let me touch it will feel even better. Then make her cum. Once she cums few time she will let you do anything.
