Surveying college student Mihoko about her underwear preferences. She's wearing a white bra with ribbon embroidery, giving off a pure vibe, but her deep cleavage is irresistible. Gradually seducing her, the urge to penetrate grows. "Huh? But... I want you to use a condom," she says. Claiming there are no condoms available, you suggest dry humping instead—just rubbing, nothing more. Her panties are already damp; they'll get ruined, so why not take them off? It's fine! We're only rubbing! "No way! I... I can feel it inside me! Uhh... uhh!" Wait, really? But you don't hate how it feels, do you?
