The Manciple's Prologue and Tale
The Manciple's Prologue and Tale is one of Geoffrey Chaucer's Canterbury Tales. Though several of the tales are sexually explicit by modern standards, this one is especially so.
The main character, January, is an old knight, gone blind from his age. He marries May largely out of lust, while she marries him for the inheritance after his death.
Sexually unsatisfied by January, May secretly sets up an affair with Damien. One day, January and May have sex in January's garden, while Damien is hiding secretly above them in a tree.
After their lovemaking, May requests a pear from the tree. As January is blind and cannot get the pear, he lifts May into the tree. She is promptly greeted by her young lover Damien, and the two of them then have sex in the tree.
The gods Pluto and Persephone, watching the affair, mischeviously decide to grant January his sight back. January sees his wife and Damien engaged in intercourse, and May successfully convinces him that he is still blind because there is no way she would do that to him.
