Lazzat un Nissa is a sex novel from medieval India written in Persian. Its about the daughter of a Persian nobleman who settles in Delhi and an arranged marriage is done with another man of similar background. However, when she visits the Mughal castle she falls in love with a Habesha (African) soldier stationed over there. It eventually descends into a cuck fantasy involving her husband, the soldier and her, as the Habesha has a giant penis and is able to satisfy her.
The novel focuses a lot on the skin colour contrast between the black Habesha and the pale Persianate beauty. The bodyguard is castrated so he also cums in her since it wouldn't make her pregnant. But they also must keep their relationship secret because if exposed they'll lose their titles and respect.

It was written by an Indian sex artist Mohammad Abdul Latif and sold many copies, especially amongst elite Mughal noblewomen who fantasized about having sexual relations with their Habesha bodyguards.
