Ayami Tomono is an active high-school substitute teacher with a soft, adorable smile and the polished look of a TV announcer. She loves her students and finds teaching rewarding, though she is less happy with the pay. Unable to suppress her sex drive, she secretly makes her porn debut, reveals that the perineum between her pussy and ass is an erogenous zone, tries bare cock right away, and even enjoys having her asshole played with.
