Momoka, a Japanese high school girl, sneaks into her room with a new VR headset, eager to explore its adult content in privacy. She slips off her uniform, revealing her petite frame, and dons headphones to muffle her moans. The VR experience immerses her, and she begins to touch herself, her fingers tracing the curves of her small breasts and rubbing her clit. She imagines the virtual cocks filling her tight pussy, her body writhing with pleasure. Suddenly, she hears her mom's voice outside her door, forcing her to quickly turn off the VR and feign innocence.
