[Watagashi Maker (Tomiko)] Verdant Youth (Hunter x Hunter) {Chin²}

Killua takes it upon himself to teach Gon what Aunt Mito never would—a boy's first lesson in self-control, delivered with a ring of fingers and instructions to gently rub it up and down. The tutorial heats up fast when Gon shyly asks if it can be done with a mouth instead, and Killua, surprisingly submissive, obliges until Gon is gasping that he really, really wants to cum. A warm, fumbling afternoon of firsts between two best friends discovering that some lessons are better taught hands-on.
