The Billionaires’ Wet Nurse 5: Carly’s Cure (Milkmaids Make Out, #5) [EPUB ebook] 

Becoming a billionaire wet nurse was literally what the doctor ordered!
 I was down on my luck and had never been touched by a man when life dealt me an additional blow—my breasts began to leak spontaneously. The doctor declared me healthy and sent me to the last place I expected…the estate of a billionaire with a special proposition. He would pay me obscenely well for the right to claim my innocence and indulge in the creamy treats that I had to offer. Little did I know that he would invite a group of friends along to help.
