An incredibly innocent female corporate employee, completely unaware of semen, is subjected to a brutal orgy involving repeated penetration by a giant penis in DAVK-097.

Why would a girl like this exist? She possesses an innocent, pure charm; just by her voice, one can tell she's the stepdaughter of a well-to-do family. Despite this air of nobility, she harbors a burgeoning curiosity about sex. Although unfamiliar with sexual knowledge, she still finds herself in a orgy with middle-aged men. Unaware of what she's doing, she's penetrated by men's penises, huge penises, one after another, her pubic hair untouched, pure genitals subjected to relentless, pleasurable thrusting, her slender waist contorting, experiencing multiple orgasms. Even when exhausted, her vagina is immediately penetrated again. Despite her attempts to escape, her small body is suppressed by the force of the thrusts, repeatedly penetrated. "Just cum like that," they say, though she doesn't understand what it means, she's still arbitrarily ejaculated into during orgasms. Finally, due to her lack of sexual knowledge, she's exploited by the adults, her womb filled with the semen of middle-aged men, her body smeared with semen, becoming a wanton girl.
