(This is a custom clip and I can make one for you too! Just send me a DM!!) You - are the conservative wife (maybe in a dress?) She - is your husband’s ex-GF (yeah, yeah, it’s a thing :) ), also in a dress/skirt…not wearing panties [Part of the key to this one is that you’re always horrified by what you are doing/becoming…] You come home from work to find your husband’s crazy ex-girlfriend in your bedroom, and you are furious.  You start to yell at her while she mostly just seems to be baiting you - and then she tosses you something (“Here, this is for you, catch!”).  You catch it without thinking about it, and turn it over to find it is a dog collar.  Now you’re really angry (“What, are you saying I’m a bitch? You’re the bitch!") but she just grins at you, waiting (“Well, if the collar fits…” “What the f-fuck does th…hurrr..that m-mean…i rrrrfffeel ffff-funny I…rrrrruf!”) You are shocked and horrified to hear yourself barking - she giggles (“Oh my god, I can’t believe that actually worked!”) as she reveals that the collar is magical and is going to turn you into the bitch you really are.  You stumble to your knees, no longer able to walk, and increasingly struggling to talk.  She laughs at you as you start to beg her to stop, terrified - but soon, all you can do is bark (“Whoops - guess you don’t get to speak any more!”).   You whine and bark at her, terrified…and then suddenly start to squirm.  She laughs as you start to bite at your dress - you suddenly feel like you HAVE TO GET THESE CLOTHES OFF.    You start to desperately try to struggle out of your clothes (if you get stuck, can’t get them off, she helps you, laughing)…until finally, panting and exhausted you are naked…sitting like a dog. [From this point forward, you can only act like a dog - your hands don’t work, etc.  Also - the more obedient you are, and particularly whenever she says “good girl” it makes you feel good and increasingly horny] You are utterly mortified, trying to cover yourself, whining…when suddenly…you realize…you want something…you start to sniff…getting closer and closer to her pussy - reaching out your tongue - and recoil in horror and disgust as you realize what you are wanting to do.  She laughs (“What’s the matter, puppy - having a sudden urge to please your owner?”)  You are disgusted - horrified - but finally can’t help yourself and shove your head under her skirt and start to lick her.   She enjoys it for a moment - then pushes you away and sits on the bed, crossing her legs.  You are whining and desperate - trying desperately to get at her pussy to lick her, but she keeps you from getting at her.  You start to bark and whine, desperate  to lick her.  She tells you to go get the collar (“Go get the collar girl, go get it!”) - you frantically go get it, and bring it to her in your mouth “Good girl!”).  She grins - and says she’ll only let you lick her if you beg her put the collar (still in your mouth) on…which will make these changes permanent.  You are horrified, whining and shaking your head - and then she leans back and spreads her legs.  Your eyes are wide, horrified - and then you rear back, whining and begging with the collar in your mouth.  You sit there, trembling and whining, as she takes the collar and puts it on you…sealing your fate.  She then leans back and spreads her legs - and practically sobbing with relief, you dive in and lick her to orgasm. When she finishes - you are insanely horny, and turn around whining and offer your pussy up to her, desperately begging her to help you…but she laughs at you (“Ew!  I’m not going to lick a girl…and certainly not a dog…”)  She does start to tease you (either with her fingers or her toes, up to you) and you whine in lust.  She says “Well, you know…there is someone in the house who could help you...”  You look confused…then horrified, shaking your head…and then whining and nodding desperately.   “Here Rover [or whatever]!  Here boy!””  she calls…and your dog comes to help you… you fuck the dog till you cum, barking and whining… Your husband walks in to find his ex-GF on the bed/couch with you frantically licking her (probably seeing the back of you only to start) while you ride Rover beneath you.  She grins “Hi honey!  I got a new dog!”  you turn, whining in horror at your new fate - but then turn back to fucking and licking, just her bitch from now on...
