Y/n and Kuroo works at the same donut shop but they both hate eachother and are big enemies. They argue everyday at work and one day y/n was walking home from work. Exhausted from all the arguments. On the road she saw a doll that looked exactly like Kuroo. But it had wings too. Y/n laughed about it and picked it up and took it home. She didn’t think much about it. When y/n was home she played with the doll. For example touching the wings. What y/n didn’t know was that Kuroo secretly had wings that he hid from everyone at work and when he gets home everyday he lets the wings out. While y/n was touching the wings Kuroo was at home chilling in his bed until he felt a pleasuring touch on his wings. The wings is his weak spot. Turns out the doll has Kuroos feelings in it and whenever y/n touched it then Kuroo would get that feeling on his real body. But y/n didn’t know that.
