Female Teacher: Get Wet and Teach Me 2002 on netflix

Noriko pours her passion into teaching by day, yet her nights blaze with jealousy and desire for a young boy named Kōichi—whose flirtatious games with customers at his part-time haunt leave her heart aflame with desire and lust. After a fiery clash with Noriko, Kōichi wanders into Noriko’s favorite bar with a chance acquaintance, Takako, only to lock eyes with Noriko, radiant and unguarded amid her drinking colleagues. In that charged moment, every lingering glance strips her naked piece by piece in anticipation for an explosive climax filled of lust.
