Several weeks passed. Thanks to the reality alteration surrounding Florence's transformation, equine herm milk and cum no longer quickly transformed humans into more slutmares. Instead their fluids, in a secret that was only known to Florence and Leia, slowly mutated women into horny broodmares.
'Right this way Mrs Tinson,' said Susan in a chirpy voice. A middle-aged woman who was dressed in high heels, a miniskirt and braless beneath her white blouse rose from the waiting area. Susan could smell the unmistakable scent of an aroused mare cunt on her. It was a scent she was deeply familiar with these days.
Susan escorted the woman down the hall and into the room with the sensory deprivation chamber. As soon as they were inside the woman stripped out of her clothes and climbed into the pod, submerging herself in the small pond of jizzcream. Without any sense of shame, she began to rub the cream into her tits and slipped a hand between her legs.
'What dildo would you like to use today?' asked Susan. She held a laminated card with pictures of dildos arranged by size, with an average human cock on one end and a horse cock the size of Leia's on the other end. The woman pointed to a foot long dildo with a flared tip and medial ring.
Susan strode over to the drawer containing the dildos and ran her fingers over some of the largest ones before grabbing the one requested. She returned to the pod and the woman snatched it from her hands.
'I'll be back in an hour.'
She closed the lid and the moans disappeared beneath the sound proofing. So many of her clients were turning into complete sluts. It should have bothered her, but she was no different and it gave her a perverse joy to usher them down the same rabbit hole she'd fallen into herself.
There was a tap at the door. It was Jenny. 'I'm nipping next door for some jizzcream. Do you want any?'
Susan shook her head. 'I'm still full from sucking you off at lunch, but thanks.'
'Suit yourself. Florence wants to see you by the way. She's in the milking room.'
Jenny dashed off and Susan made her way to the milking room. Florence's scent greeted her before she even entered. Despite being pregnant she was still in heat, and any slutmare that got within a few feet of her ended up mounting the broodmare.
'Jenny said you wanted to speak with me?' asked Susan.
Florence waved her in with her free hand. Her other remained between her legs, furiously rubbing her clit. From the amount of milk she was letting down into the tubes from her four tits, she was coming off the peak of an orgasm.
'Yes, yes,' she panted. Her hand stopped and she took a moment to regain control of her breathing. 'Dorris is coming by in an hour to work on the accounts. She still thinks you're on her side so I want you to bring her some coffee. Mix in the usual jizzcream. Complain to her that your 3-o-clock switched to Jenny and that you're sick of all the housewives with their perverse farm fever fetish. Then describe in excessive detail what you saw Jenny doing with Mrs Denvers this morning.'
Susan nodded. 'I take it I should omit what I was doing?'
Florence detached her cups and grinned. 'I don't think you masturbating would shock her. She does enough of that at home these days herself. But still, it's probably best not to rattle her trust in you just yet.'
'Yes ma'am.'
Florence sniffed the air. 'Perhaps some extra perfume would be a good idea as well. I can smell your snatch, and as lovely as it is, it does give you away as a raging slut.'
Susan blushed. 'I didn't think it was that obvious.'
'You're practically in heat dear.'
