Grab a quick breath and come back

You swim over to the other side of the dock and surface behind an old tire hanging on it. You can't make out all of the conversation but it sounds like the girls are complaining that there are not enough guys at this party.

Duh! You made sure of that.

You hold your breath and swim back over.

You pull aside the thong of the new girl. Her pussy is bare from top to bottom. You begin to lick her sweet cunt as you use your finger on the other girl.

Since the new girl didn't freak you figure the first girl must have told her what had been happening.

"I like this party," you think the thong girl says.

Your running out of air and can't decide what to do.
