An inconspicuous classmate reveals an amazing bust! The allure of an I-cup—precocious yet completely oblivious to her own appeal. Hayasaka-san is the plainest girl at the workplace; she’s always hunched over and never says a word. One day, I happened to catch a glimpse of her changing in the locker room and couldn't believe my eyes. Hidden beneath those clothes was an absolutely incredible I-cup bust! Unable to control my desire after discovering her amazing body, I devour those defenseless, massive breasts right there on the premises!
