Momoka, the sweet-faced virgin, finds solace in her secret onani routine, hiding in her room while her family believes she's studying. She slips off her panties, her small hands trembling as she touches herself for the first time. Her fingers explore her tight, untouched pussy, gasping at the new sensations. She imagines her crush's touch, her body responding eagerly as she rubs faster, her juices coating her fingers. She's close, so close, when suddenly, she hears footsteps outside her door. She freezes, her heart pounding, as her family member knocks, calling her name.
