Jade Bleu 
The Billionaires’ Wet Nurse (Milkmaids Make Out, #1) [EPUB ebook] 

Becca has a most unusual job—she’s a private wet nurse for a billionaire with wildly eccentric “nutritional” demands. Her sexy boss has kept things all business—and she’s over it. She decides to turn the heat up and show him she’s got a lot more to give than an ample milk supply. When she succeeds in seducing the boss, he one-ups the arrangement, offering her double duty for milking and sex—together with his billionaire brother.
An erotic short featuring hucow creamy treats and unprotected billionaire sex.
