[Akatama (Sakurafubuki Nel)] Hotai! [SquigglesJP]

Karin's uncle has been giving her very hands-on lessons about where babies come from since she was small, and what began as a curious girl learning what an 'ochin chin' is has only grown sweeter with time. Between cozy evenings where he cooks for her and daydreams of making her his wife, and study sessions where her health textbook ends up abandoned as he fingers her glistening slit, their shared secret keeps getting harder to keep from mama. So when he asks whether she wants him to cum deep in her womb, her breathless 'let it out' promises this little sex-education course is nowhere near finished.
