[Master of Expansion] Little Manga [Full Color]

A bubbly schoolgirl spends her tram ride gossiping about a classmate's love confession while cheerfully inviting a sweaty older stranger to play with her however he likes. What begins as idle groping escalates into full-arm fisting that visibly reshapes her belly, all recounted mid-conversation to her friend across the aisle. By the final page the expansion is pushed to its grotesque extreme, leaving the girl beaming and the man who started it all weeping.
