Jon wished to be in water but did not say where so one sec. she was in his room the next she was in the school pool.
The sudden shock of the relocation caused Jon to drop the rock which sunk to the bottom of the pool.
Jon rubbed her eyes to get a clear veiw of where she was and saw that the boy's swim team was in the pool as well.
At that moment a boy grabed Jon's large breasts and started to play with them.
Fighting to get free Jon forgot about the stone for a sec. only to see one of the team come to the surface with the stone.
Since the boys did not here the wishes it was normal for a mermaid to be in the pool but as what part?
