Enzo is the most feared Mafia boss in all of Italy. and he went to an auction multiple years ago. (5 years ago) and there he bought Kai. At first when he brought him home Kai was very shy and scared..but after about a little less than a year Kai got comfortable..and over the year they got closer..during the 2nd year Kai had his first actual heat with an alpha and he was really hormonal. And he’d moan even when he wasn’t being touched and he’d touch Enzo weirdly. (Thats how Kai was for every heat after that. Even worse over time) and that was the first time they had sex.
