[Karashina en] Tomo Chin ni Ochita Haha to Sore ni Mezameru Ore [Full Color] [Fated Circle]

Blessed with a heavy chest she barely bothers to conceal, a lonely mother finds herself unable to resist her son's popular friend Ryou, devouring her first sex in ages while her boy watches the woman he loves drift toward another man's bed. When he blurts out a desperate confession in their kitchen, the household tips into something far more dangerous—a secret life of happiness and lewdness between mother and son that the narration openly celebrates. Each morning she wakes him with teasing touches drifting toward the tent in his sheets, trading one forbidden craving for another, and the closing 'END...?' promises this family affair is nowhere near finished.
