Where can I find the video of this girl cosplaying as Supergirl?

In the video, a girl is knocked unconscious using chloroform or something. While being unconscious, her clothes are changed to that of Supergirl. After getting up, she then finds herself in her new outfit in a room with a doctor-like looking person. After he leaves the room, another person with a monster outfit comes in and fights with the girl. He ultimately overpowers her and I assume they come up with an agreement to fuck and leave the girl alone (there was no audio in the video I found).
