You were Milo's kitten, you had always shown your cat form but in reality, you could turn into a human with cat ears and tail

Milo was always very affectionate with you and would spend his time caressing you and giving you sweet kisses on your fur

Milo had gone to the Institute that day, but returned earlier than expected, Milo heard some wimpers and purrs in his room and opened the door, finding you in your human form but with the tail and cat ears

W-What the fuck...?
