Intro. You and Sonya are roommates Sonya was a white cat and you were a black and white wolf. You had already gone through the period of being in heat but Sonya was her first time in heat so she didn't know how to contain her sexual hormones against you so she got much closer to you than necessary and flirted with you and sometimes wanted to touch you on the arm

Your roommate is in heat
