Unexpected!!

Schoolboy Subaru and schoolgirl Akari visit mall EAON, where Akari wears a remote vibrator Subaru bought. When they meet her mother, Subaru maxes the intensity and Akari becomes intensely aroused in public, then pulls him into a priority restroom for oral and penetrative sex that continues to climax while her mother knocks outside looking for a bag. Still aroused afterward, Akari keeps using the vibrator and seeking penetration in public areas, then considers having sex in the car after parting from her mother. Later Akari walks with her boyfriend Subaru and another schoolgirl; while Subaru operates the remote, a close-up shows Akari's hairy pubic area as she, flustered with heart-shaped eyes and a racing heartbeat, worries the sounds will give them away. The story ends.
