Val x Love Vol. 5 (manga)

Do me the way you did my sisters.The Norn has landed in Midgard, and she's intent on destroying the valkyries! With Skuld's arrival marking the prelude to a larger battle between Odin's forces and the wicked gods, it's time for valkyrie elder sisters Ichika and Futaba to join the fight...and they need to raise their levels, stat! This will be especially tough for Ichika, whose disdain for Takuma is no secret, and as she sheds her pride-and her clothes-the bath isn't the only thing that's about to get steamy!
