Looking for 3P BL

From what I can remember one day the ukes sex friend invites his brother (twin if i remember) to have sex with the uke and for a while its a 3p until the brother that was invited starts getting jealous of his brother for sleeping with the uke and the ukes starts falling for the brother and not the sex friend. I hope this is helpful. I'd really like to reread it and I appreciate the help from anyone who might have a clue :)
