Here an old(?) man with a red nose peeks under the skirt of a not unwilling young woman. We are looking at a brothel-scene here: the red clothing of the woman makes it likely that she is a prostitute. The pipe leaning against the chamberpot also points in this direction: ‘cleaning one’s pipe’ is an old eufemism for visting a brothel.
The liquor bottle and the man’s red nose are an indication of excessive drinking. The brazier, the slippers and the stockings serve as sexual allusions.
