Dare Petra to show off her body

“Petra!” you exclaim abruptly after a moment of thought. “Time to get out o’ yer shell, hop out and strut your stuff. Go touch that wall and come back” You point over to the far wall near where you entered.

“Like… all the way?” she says meekly.

“It’s not that far a walk.” You tease playfully. Her face goes red but she approaches the shallows. Still concealed by the water, you watch her ponder her strategy between speed or covering her delicates. She wraps an arm across her breasts and another between her legs but both you and Gilly get a clear view of her ass as she leaves the water. She quickly walks to the far wall touching it with a foot before making her way back.

Half way back she picks up the pace but slips on the wet rocks. Her arms shoot out on instinct to grab anything on the way down but she lands on her back with a wet smack. Her momentary vulnerability puts everything on display. You watch in amusement but Gilly looks away modestly.

“Ye alright Petra?” you shout from the pool.

“Y-yea.” She says picking herself back up. She quickly covers herself with her arms once more and returns to the pool. Both her and Gilly are noticeably red in the face now.

“So next to pick is Gilly aye?” all eyes turn to Gilly as he weighs his options.
