[Nani mo Wakaranai (Muniko)] I'll teach you.

A bubbly, busty Umi-chan arrives expecting an enthusiastic game with a masked stranger who finds her even cuter than in photos, only to quickly find herself collared, leashed and trembling on all fours. Under his calm, praising guidance, her petplay training moves from a nervous city meeting to a secluded outdoor park where she learns to pee like a dog, answer with an obedient woof, and truly belong to him, her sweating big breasts and flushed body caught between humiliation and bliss. Treated like a naked object in public, she discovers the shame feels amazing, surrendering to wanton masturbation as she begs breathlessly to know if she is good enough.
