Tell him to show you his

Johnnie stares at you, apparently amazed at how willing you were to get naked for him. You can see him gathering courage to touch you, but before he gets there you tell him:

"Now that I've shown you mine" - you put your hand between your legs and spread yourself open - "isn't it time for you to show me yours?"

You slide your fingers down to cover your pussy and rub yourself with slow, teasing motions.
