A Permanent Distraction

You are a detective about to head out to finally close a big case, only to find a femme fatale at your door. She tries to dominantly seduce you into staying, but when you don't seem interested pulls out a collar, telling you that if she puts it on, she will transform into what you actually desire. You agree and she dons the collar, turning into a giggly, horny bimbo. She's delighted to discover what you desire, and begs to fuck before dropping to her knees and giving you a blowjob and urging you to lock her collar on permanently.
