[Karuno Kamo] Next Door Oneesan Part 2

A shrunken boy races a five-minute timer across his neighbor Aoi-san's towering body, climbing her huge breasts and giant panties in a gachapon treasure hunt she's rigged so he has to grope every curve along the way. Each round leaves him smaller—until even her fingerprint dwarfs him and she teases that any tinier and she'd crush him without noticing. The bath brings the twist: she asks if he meant it when he said he wanted to be her boyfriend, then playfully vows that once he grows back, she's going to shrink him again.
