Goddess of Pleasure by Ramona James
Cindy came. And then came harder as she felt her slut respond and climax ferociously with her, her tongue itself lost in spasms of relentless pleasure at the recognition of her Mistress's climax. Cindy's body convulsed even more strongly in response as the two lost women sent themselves into a cycle of higher and higher pinnacles of orgasmic pleasure, until they were nothing more than a molten heap of lust-fire, their clits the white-hot coals that re- ignited their flaming passion every time it began to lessen.
