Take the soap and introduce yourself.
From Create Your Own Story
"That's a nice name!" Liz says as she turns around and goes back to her shower.
You turn back to your shower and nonchalantly rub the bar over various parts of your body for a few minutes. You notice that the girls are no longer shy about facing you, so you revel in the fact that you can sneak in as many glances as you want. Over the next few moments you hear the girls conversing about what they are going to do once they leave; it seems they've decided to simply let you keep the soap. You're really wishing you had grabbed that busty slut's tits while you still had the chance.
They're going to leave unless you do something, so you hastily decide to turn around and say something. You take a few small steps forward, slowly, and soon you have the attention of both Liz and Beth as you stand in front of them. You can't tell which girl is which, but damn their big tits look good as they cross their arms under them!
"Yeah?" Beth says.
