"Teacher...no, calling you 'wife' would be more exciting, wouldn't it?" Double incestuous relationship, beautiful teacher Kitagawa Mio, UPSM-188

A promiscuous female teacher, no longer satisfied with mundane sex, cheats on her husband with a student's parent! She uses a vibrator for toy-like discipline in a pre-arranged hotel room! She has sex with a colleague in the classroom! She engages in perverse masturbation in the gym storage room while wearing student sports shorts. This morally corrupt teacher is consumed by lust.
