Looking for bedwarmer Merlin fic
Hello!
[hidden]I'm searching for an ao3 fic where Merlin became Arthur's bedwarmer. Arthur basically forced him to stay in his room and he makes Merlin gain weight. I think I recall a scene where Merlin watches Arthur training from the window, but Arthur is very overprotective and won't let Merlin leave. I might be misremembering but I think Arthur also might get Merlin to start lactating and there is some feminization. Any help is appreciated!
