A timid Japanese teen, new to cosplay, finds herself in a secluded warehouse stockroom, blindfolded and already aroused. Her experienced partner, hidden behind a costume mask, leads her to a safe word, but her inexperience and nerves make her hesitant to use it. She's a virgin, but her curiosity and the taboo thrill of being recorded push her to explore her boundaries. Her body responds eagerly as he teases her, his hands exploring her petite frame, his mouth tasting her innocence.
