[Sponge Gum] The Art of TS [Full Color]

A doting fox spirit with a heavy, milky chest spoils her favorite young playmate, letting him nurse straight from the source until her breathless 'here it comes!' turns the steaming bath into a soaked, gasping mess. She models schoolgirl, gym-class, and maid outfits just for him, but the game tips into a full body swap—and the boy discovers firsthand how overwhelming a girl's body can feel while she gleefully wears his. The afterword twist stings sweetest: her promise that one more round will turn them back to normal is a lie, and the flustered pair are stuck together far longer than either planned.
