Cuckold Trilogy: Book 2: Swinging Cuckold
Joanna has feminized her husband and locked him in chastity. Sissy Coco, formerly Craig, is now nothing more than a maid and servant in the household. And while a fawning and obedient sissy maid is useful, Joanna still wants men in her life.
A local swingers club provides the answer, giving Joanna the men she needs and heaping even more humiliations on the hapless sissy Coco.
