The innocent and youthful "Himari Aizuki" is mercilessly creampied in a wild 4SEX session after being teased and impregnated by men! She starts working out at the gym influenced by her fitness-obsessed friend. When she changes into the provided training wear, her panties become see-through. Personal trainer's advances lead to increasingly bold actions until he finally inserts his bare cock inside her without hesitation! Her body is caressed and pleasured until she's filled with hot cum...
In another scene, Himari takes a taxi ride where she's tricked into drinking a drug-laced beverage meant for sex slaves. Unaware of its contents, she becomes dazed and helpless as the driver orally pleasures her unconscious body before taking her to his lair against her will. There, she's forced to perform sexual acts under threat while being repeatedly filled with hot cum from his massive cock.
On a date night, Himari's boyfriend orders her to hide a vibrator in her panties which leads to an embarrassing public arousal when controlled remotely. In desperation, they engage in a passionate outdoor sex act on the balcony of her apartment building.
Later, Himari discovers that she's been followed and photographed by a stranger who continues to harass her even after she moves away from the city center. One day, she's ambushed in a park bathroom and subjected to a terrifying ordeal involving forceful blowjobs and ejaculations directly into her mouth. Afterward, she's drugged, kidnapped, and gangbanged relentlessly while being continuously filled with hot cum. Finally, she wakes up only to find herself being used as a breeding object by yet another man who takes advantage of her vulnerable state.
