El pecado, 1913 Julio Romero de Torres (1874-1930)

The picture has something of this: people, woman, nude, girl, two, portrait, love, man, group, music, family, reclining, indoors, light, dancing, recreation, wear.
Perhaps it’s a painting of a woman laying on a bed in front of a group of other women and one of them is holding a snake in her hand.
