[Nozarashi Satoru] Happy Family Get-Together (Tabete wa Ikenai)

After her father's death, schoolgirl Aya comes home to find her lonely, big-breasted mother bound and broken by a mysterious 'Master' whose twisted household rituals turn mealtime into degradation. The grieving girl's tearful resistance crumbles as she's gagged, tied, and trained alongside her mother — drinking the Master's piss at her mom's tearful encouragement before being fed by hand. By the final page both mother and daughter serve in matching maid outfits, worshiping their new 'Daddy' together and vowing their strange little family will never be lonely again.
