Casual amateur: a nighttime public blowjob on a crowded train

In a crowded public train, under the dim light, a 21-year-old woman with long, black, straight hair and casual attire sat casually. Her slim face was framed by her busty figure. Unbeknownst to the passengers, she was giving an impromptu, passionate blowjob, her tongue skillfully teasing, her open mouth catching each spurt of cum squirting out from the man's penis. The train's windows revealed a night outside, adding an element of amateur porn to this unexpected spectacle. As people took furtive photos, she gracefully swallowed the culmination of their shared secret.
