[Saimonke] Kaa-san to Shitai Koto ~ Zetsurin Musuko to no Seikatsu Kaisou Hen [LiChungChin]

A devoted mother with impossibly soft, heavy breasts and a tender, yielding body finds her maternal resolve crumbling under her virile, insatiable son's relentless desire for hands-on sexual knowledge. When he threatens to take his curiosity to a girl in his class if she refuses, guilt and forbidden arousal collide as she reluctantly offers her own body as his lesson, quickly discovering how readily she accepts his hot, pounding urgency. What starts as a hesitant, once-only compromise deepens into obsessive, creampie-filled nights of insatiable intimacy that leave her flushed, trembling and swelling with the undeniable consequence of their life together.
