When the quiet girl turns out to be the biggest slut?

I promise I've been a good girl

When the quiet girl turns out to be the biggest slut?

I promise I've been a good girl

I promise I've been a good girl

I promise I've been a good girl

I'm not the shy girl you used to know

I promise I've been a good girl. [f]

I could be the girl from your sweet fantasy

This girl has the naughtiest thoughts

Just a girl who needs cuddle

I promise I've been a good girl [m4f]
