I need money. An enormous amount of money.

My father's dying of cancer. We don't have enough money for the surgery that will save his life. I'm racing against the clock to get enough money to pay for trie-and-true cancer treatment that insurance won't cover.
Two billionaires offer me a simple deal: my v-card and a month of my time in exchange for enough money to pay for the surgery.
I accept. And now I'm living with two men. Brian is the smooth, courteous gentleman. Samuel is the rough barbarian. And together, they're about to rock my world and introduce me to things I've never even heard of, let alone tried.
