I'm not sure about a specific one off - hand, but you can start by looking on popular fanfiction websites. Search for tags like 'Percy god of lust' and sort by the highest rated or most reviewed stories. There might be some hidden gems there.
There could be a fanfiction where Percy is trying to redeem himself as the god of lust. He realizes that his powers have been misused or misunderstood, and he sets out on a journey to change how others perceive lust. This could involve him helping mortals and other gods to form more healthy and respectful relationships, rather than just focusing on the physical aspect of lust. It would be an interesting take on the character and could make for a great fanfiction.
A really cool fanfiction idea could be Percy teaming up with other gods who represent different aspects of love. Together, they form a sort of council to deal with matters related to love and lust in the world. Each god brings their own perspective and powers, and Percy has to learn to work with them, which leads to a series of adventures and character growth for him.
