"there's a very fine line between love and hate." after joining the BAU, Y/N must navigate the complicated feelings she's starting to feel for her difficult co-worker, Spencer Reid. *WARNING that this story does contain a heavy DD/LG (daddy kink) component, so if you aren't into that, DO NOT read.* *contains smut*

"I could tutor you, but I don't think you'd be able to concentrate." • • • When Cassandra Berry gets offered a shitload of money and a place at any college of her choice, just to con a man and getting pregnant with a said man, the answer seems pretty straight forward; Yes. - But Harry Xavier Devon is no mere fool. With two millennium prizes on his back and renowned around the world as the next Newton within mathematics, Harry easily sees through his brother's ploy to have a woman seduce him and get her pregnant when he himself can't have children. His brother in desperate need of an heir for his business empire, but Harry has no intentions of playing the scapegoat. Flipping the play against his brother, he pays Cassandra double the money to continue lying to his brother that they *are* having sex. He thinks he's gotten his revenge when it suddenly appears he's gotten more than he bargained for. Cassandra is no shy woman, or as previously thought, just a money-grabbing whore. Stuck in the same house together for a whole summer could prove to teach the mathematician that some things can *never* be calculated... - Especially when dealing with a (horny) woman.
