They just couldn’t help themself.

It was early evening, and Vicky was having a nap in the living room after a long lunch shift. Sam walked in to find her curled up on her pet bed in front of the couch, naked aside from her collar and tail plug, snoring gently into the pink pillowy surface below. Her rubber pig toy was nestled beneath her chin - she probably shoved it in her mouth when she laid down, but it fell out while she slept.

Gazing down at her, Sam was struck, as they often were, by a wave of love and lust for their beautiful, brainwashed partner, a woman who’d reached the point where dozing on a dog bed in the middle of her living room, with a chew toy in her mouth and a fluffy tail protruding from her butt, was so normalised she did it without even thinking about it (without even being hypnotised not to think about it). She’d been conditioned so thoroughly, over such a long time, that she was now, in her default state of mind, a completely domesticated pet girl.

That’s my fiancé, Sam thought with an adoring smile. Then they bit their lip, their stare turning more intense, and continued, I’m gonna fuck her right now.

Whipping down their shorts, they lowered themself onto the floor and snuggled up close behind their housewifepet, threading their boner between her thighs. Burying their face in the back of her neck, they gave her small, soft smooches while their left hand reached around her waist and began to massage her labia. Unconscious though she was, Vicky’s body responded well to her Master’s touch, her cunt rapidly lubricating.

Vicky’s my free-use pet, Sam thought, smirking into her shoulder. I can fuck her whenever I like.

She didn’t even have to be awake - that had been established for a while now. Their relationship was so very CNC already, and Vicky had finally admitted that she found the idea of being taken in her sleep by her Master irresistibly hot. So somno had been put firmly on the table - Sam now had carte blanche to have sex with her at any time, even while she slept, unless she specifically requested otherwise. She’d even undergone hypnotic training so that if she woke up while being fucked, she’d simply fall asleep again. (That had taken some practice to pull off - not that either of them had minded the extra effort...!)

Sam had felt a little awkward, at first, about taking advantage of their sleeping partner. Even with clear, firm, blanket consent, it still felt strange to cross what seemed in their mind to be a boundary. That changed once they, too, were subjected to a little hypnotic conditioning, although at first they were oblivious to it. Even when they finally recognised the phrase that popped into their mind whenever they felt the impulse to ravish their pet as a mantra she planted in their head, they still found it very easy to embrace it.

Now, any time they looked upon their lover with lust and longing, their inhibitions were drowned out by a compelling quote. Vicky’s my free-use pet, they reflected again, as they slightly lifted her left leg and eased their dick into her wet hole. I can fuck her whenever I like.

The puppy-girl’s tail tickled Sam’s belly as they began to thrust back and forth, their arm curling round her torso, their hand fondling her heaving tits. If their increasingly insistent rutting disturbed her from her slumber, she soon nodded off again in their embrace, rocked to sleep by the rhythm of the strap-on sliding inside her, overcome with pleasure and contentment, at her happiest because she was full. Indeed, she’d later tell Sam that she had no recollection of the somno sex, only realising it had happened when she woke an hour later to find her fiancé and Master spooning her, now asleep themself, their cock still buried to the hilt inside her.

For now though, Vicky lay dormant, dead to the world, drooling into her pet bed, while Sam wrapped their limbs around her, furiously fucking the free-use pet they would soon be lucky enough to marry.
