[upStick (Ario Orio)] Piano Kyoushitsu no JS Kanojo x Swapping NTR Kanketsu-ban

During a piano lesson the hesitant student says, "If it starts to hurt, I'll stop right away," and after a brief hesitation replies, "Fine, just this once," while the confident peer whispers, "We could, but I'm always holding back while looking at Sayuki‑chan’s sexy body," and later a teasing voice urges, "Why don't you get that tiny little dick hard and come over to my place," leading to a secret swap that is captured on a hidden phone, ending with a playful claim that the recorded video shows the pair having lovey‑dovey sex.
