«Lady Wycherly's Secret» by Robin Bond

Guinevere
is shocked to discover after her marriage to British diplomat Lord
Wycherley that her husband is gay. However, she’s determined to make of the most of the situation. Once she gives him a son and heir, which is all that he wants of her, she finds her sexual satisfaction elsewhere.

Guinevere’s
friend Lydia introduces her to a circle of dominant women who enjoy
disciplining submissive young men, and she quickly discovers she has a taste for such pleasures. She forms an attachment to one of the boys,
Johnny, with whom she explores a range of new sexual experiences,
including anal intercourse and a threesome with another man. When she meets Edmund, a young man of her own age, she discovers that Edmund is just what she is looking for, a good-looking boy with a submissive
nature whom she can train to serve her. Edmund is remorselessly
disciplined, caned, whipped, denied orgasmic relief, and forced to perform a series of humiliating acts. She teaches him how to pleasure
her with his mouth and his cock, and keeps him, Quite literally, on a
tight leash. Later, she takes Edmund to Paris, where she makes him perform sex acts with other men, and cuckolds him with a man she picks
up in the hotel while Edmund is forced to watch.

On
her return home, Guinevere is stalked by a mysterious stranger, who threatens to make public her husband’s homosexuality unless she steals
some important diplomatic papers. It will take the assistance of one
ingenious sleuth to protect her husband’s secret and thwart disaster.
