His mistress's eyes are like the rising sun.
His wife’s are a setting one.

His mistress's lips are red and wet.
His wife’s are pale and dead.

His mistress's voice is a bird of Spring.
His wife just mumbles and refuses to sing.

As pillows are his mistress's breasts
on an overheated chest.
His wife’s breasts smell like sour milk.

A lukewarm relationship.
