Sold To The Ruthless Alpha

Alpha Damien is a multi-billionaire. He's a mafia and a strict businessman. He runs a lot of businesses and also gives loans to people... if you can't afford to repay your loan, he collects whatever he wants to take from you that is equivalent to the loan. He's a ruthless and fearless Alpha, but he finds out his mate is the daughter of his own of his debtors, and she has lived all her life as a nun... How would a nun satisfy a ruthless Alpha???
