A story of lactation and diaper play featuring Takkun, a diaper newbie, and his affectionate mommy Marie. At Omu Land Usagi, Tsumiki House's mommy friends prepare a cozy room where kids can enjoy diaper play anytime. When Takkun shares his dream of drinking breast milk while playing in diapers, Marie happily says, "I absolutely love cuddly little ones!" and decides to play with him.
Marie gently guides Takkun through his first diaper experiences—helping him put on diapers, reading books together, and cherishing their time. She even pre-chews snacks before feeding them to him, creating a warm, family-like atmosphere. Finally, Takkun gets to drink his fill of Marie's sweet breast milk while being held in her arms, and both are clearly having a wonderful time.
The slightly naughty Marie smooths and cares for Takkun's penis, tenderly supporting him from behind during potty training on the potty seat. Despite acting like a baby, Takkun feels the urge to pee, and when he does, Marie calmly reassures him, "Don't be scared, it's okay," as she gently applies warm, slippery lube and wraps him snugly in his favorite diaper. "Let's take good care of Takkun's little penis," she whispers, treating him with love and intimacy, as if they were lovers.
