The innocent loli girl "Hazuki" becomes obsessed with corner masturbation. One day, she's discovered by an older man who tempts her with, "Let's play pretend adults?" and is gradually drawn into the adult world. Lured by sweet words, she soon finds herself completely tamed as a cumdump. Amidst the rhythmic slapping sounds—pachin pachin, pachin pachin—her pure, odorless pussy is steadily filled with foul-smelling semen. "No... my stomach feels weird... If I get pregnant... I can't tell Mom..." she whimpers, as her loli womb swells with thick, milky cum. A shocking clash between her innocent heart and adult desires unfolds.
