[Kutsu no Shita (Kutsuno)] Your Sky-colored Pencil (Ongoing)

Your Sky-colored Pencil follows a nervous schoolboy in glasses and a uniform who is startled when a classmate pokes his backside during the last club session, prompting confused gasps and frantic attempts to hide his embarrassment. The tension rises as the teacher’s firm grip and a binding rope suggest a bondage scenario that teases the underlying yaoi dynamics of power and submission. With an R18 warning and adult‑only content, the story promises intense, forbidden encounters between the characters.
