[Jack to Nicholson (NoriPachi)] Fast growing baby

Suddenly handed a young boy to raise under a 'child raising law' she never signed up for, a flustered middle schooler fumbles through maternal duty until a shared bath changes everything—her clingy little charge begging 'mommy' to peel back his foreskin and clean every inch of him. What starts as awkward caretaking escalates into a middle schooler's footjob and long, slurping nursing sessions at her still-growing breasts, his babyish 'goo goo' melting her resistance with every shiver. By the time she's cradling him close, murmuring that she thinks of him as her baby and loves him very much, this fast-growing pair has turned bewildered obligation into something tender, blushing, and deeply wrong in all the right ways.
