Giselle Renarde 
Adam and Sheree’s Family Business [EPUB ebook] 

After a summer of forbidden love, Sheree crashes at the townhouse her brother Adam shares with his roommates. With no spare rooms, she takes the couch, promising it’s only until she finds a job and a place of her own. 
But Sheree doesn’t seem all that interested in working. She lounges around all day, tempting and taunting her brother while she annoys Adam’s rent-paying roommates. Adam tries his damnedest to keep his hands off his sister, but he just can’t help himself. He’ll succumb to temptation, but not in the house. Adam won’t risk his friends finding out about their taboo relationship.
When Sheree starts a sordid family porn business behind his back, Adam can’t believe how she’s taken advantage of him. Will he kick his sister to the curb or choose to be used in every way possible?
