Yowa Yowa Sensei – Episode 4 (ES)

On the class camping trip, Akihito tries to let everyone see Hiyori-sensei’s good points, but her super-weak body causes endless trouble. He ends up constantly caring for her — carrying her, helping her walk, and staying by her side. Hiyori’s desperate attempts to act like a proper teacher only make her seem scarier. The tension finally breaks during a forbidden mixed open-air bath encounter and when the two get locked together inside a tight closet at the inn, leading to intense body contact and rapidly rising romantic and physical closeness.
