At some point the "battle" in the river looked so fun, that Eris and Camila also jumped into the water and started participating, of course that led to some simple formations to be used to raise waves against Aster and Mylene as Eris wanted to tease her friend.
"Hey, that's cheating Eris", said Mylene as she was dragged by a wave, the upper part of her bikini nearly drifted away but she managed to tighten the laces on time.
Eris chuckled and then stuck her tongue at Mylene before saying.
"All is fair in love and war~", her voice was pretty suggesting which made Mylene feel as if a vein was popping on her neck.
Eris suddenly had a bad premonition which was confirmed a second later, when Mylene used her monstrous strength to kick water at her, creating a current that nearly tore off the lower part of Eris's bikini.
