Vicky blinked dazedly, staring at the ceiling above her. She thought maybe she was supposed to be doing something... but what? Her mind was so foggy, full of the familiar soft pink mist that made her feel so slow and stupid. Trying to think just made her giggle, and squirm, and nestle into the duvet beneath her.

Her skin was so sensitive, it felt like it was fizzing. And nowhere felt better than her boobs. Wait - she remembered Master saying something about touching her tits. Was that what she was supposed to be doing? She hoped so. She loved touching her tits! Vicky grabbed hold of them, and electricity instantly fired through her body. She let out a moan of pleasure and started to grope herself eagerly. As she writhed, her dildo inched inside her, reminding her of its presence, and of the soft rope wrapped around her crotch and butt. Fuck, she felt good.

But hold on - there was something else she remembered Master saying. Something about getting dumb... getting dumber? Something to do with her tits, and getting dumber... What was that? “Umm,” she said out loud, finding it an effort to make even that unintelligible sound. If only Master was here, she could explain again! Master was sooo much smarter than Vicky.

She felt a caress along her thigh, and barked with surprised laughter. Of course, Master was still here! She was sitting on the bed next to her! Vicky couldn’t contain her embarrassed giggles. She was so stupid, she’d forgot her wonderful owner was right beside her. Maybe that was too stupid, actually. She liked being dumb, but she didn’t want to be so dumb she forgot the light of her life!

“How,” she tried, then stopped, already forgetting what word she was going to say next. It was really hard to think with those hands squeezing her tits. She loved that so much, but if they could just stop for a second so she could collect her th- oh wait, they were her hands. Giggling again, she managed to stop fondling herself and slowly regained a little bit of composure. “What’s... making me... dumb?” she eventually forced out.

“Aw, sweetie...” Master loomed over her, meeting her gaze, smiling wickedly. “You forgot, didn’t you? You get dumber when your boobs are touched. They’re like a dial for your brain, and whenever they’re touched, the dial turns down a little more, until you can’t think at all...”

Vicky stared up at her with wide eyes, struggling desperately to understand this. “My tits... make me dumb?”

“That’s right,” Master cooed, as if talking to a small child. “You tried so hard all day not to touch them. You were doing so well - even though I didn’t dress you this morning, so they’d be out and on display and easy to get to... Even though I made them extra sensitive... You held out for so so long. I was really impressed.” She smirked. “But you couldn’t stop me from touching them. All I had to do was come up and grab them, and you let me, because you’re such a good girl...”

I’m a good girl, Vicky agreed. It was the first coherent sentence she’d managed to think in quite a while, but it also wiped out all her other thoughts in the process, including everything Master had just told her about her breasts.

“And then all I had to do was play with them until you forgot what happens when they’re touched, and then get you to take over and finish off the rest of your brain,” Master chuckled cruelly.

Vicky giggled along with her. She’d gone past the point of understanding much of what Master was saying, but she got the sense she was making fun of her. And she really liked that. She was weak and dumb and helpless, after all - it was only right that she should be mocked. Besides, it was hard to be upset about it when she felt so good... Why had she stopped playing with her titties? Something about a dial, and not thinking? She couldn’t remember. She started playing with them again, whimpering happily.

Master laughed. “There you go! You don’t need to understand what’s happening to you, do you? Just keeping playing with your boobies, like a good, dumb little bimbo...”

Vicky shivered. She liked being a dumb little bimbo!

“I bet you’re so stupid by now, you can’t even spell your name. Go on, pet, give it a try!”

Master was telling her to do something. She had to try, even though her brain really wasn’t up to it right now. What was the first letter? God, her boobs were so sensitive... Her dildo was fucking her so nicely... First letter, come on now, Vicky. Vicky, Vicky, Vicky... What was the sound at the start of that? The ‘V’ sound? Was that it?

“V,” she mumbled at last, the effort of thinking making her brain crackle and pop. That, combined with the next squeeze of her boobs, shrank her intellect still further. She mewled - not only could she not think what the next letter was, she didn’t even remember what she was trying to spell any more.

Master was clearly finding her confusion hilarious. “That’s it, my silly little slave girl... It’s just too hard, isn’t it? Too much effort to think. All you can do is lie there and play with your tits.”

Tits. Something, some tiny flicker of memory, entered Vicky’s dim brain. A phrase - something she remembered, something buried deep. Something she felt the need to say.

“N-nuh-no thoughts,” she burbled, bubbles of drool popping out of her lips as she struggled to articulate her words. “Just tits...”

Master’s eyes widened with surprise, and flickered to Vicky’s tits.

“No thoughts, just tits,” Vicky said again. Something about that phrase was really exciting her, making her mouth work better even though her mind was almost completely gone. “No thoughts, just tits!”

“No thoughts, just tits,” Master echoed, her tone suddenly a lot less commanding. She sounded, and looked, very sleepy all of a sudden. And her gaze was fixed on Vicky’s chest. Master liked her tits too! The bimbo stroked around them, trying to show them off more, to make them more visible.

“No thoughts, just tits,” came out of her mouth again, without her really needing to make herself say it. She was glad the phrase seemed to be coming out of her automatically. She didn’t have the mental strength to form words now, so she’d just let her voice get on with saying that sentence while the rest of her gave up on thinking and gave in to the intense pleasure she felt.

“No thoughts, just tits,” Master droned.

“No thoughts, just tits.”

“No thoughts, just tits.”

“No thoughts, just tits.”

“No thoughts... jus... tiiitsss...” Succumbing to the titnosis, Master slumped over, burying her face in Vicky’s chest, and sank into the welcoming arms of hypnosis.

Her face, her warm breath, her soft hair on Vicky’s tits, and the trickle of drool that fell into her cleavage, utterly short-circuited Vicky’s brain. “Guh - uh,” she spluttered, her limbs going slack, as the last scattered fragments of her mind vanished, and she, too, fell into a dark abyss of blankness, her eyes rolling back in her empty head.

***

Twitching and groaning, Samantha finally managed to wrench herself out of trance, awakening to find her face still resting on Vicky’s chest, using her left tit as a pillow. Dazed and disoriented, she sat up and shook her head hard. She glanced at the clock on the wall, and let out a startled laugh.

Shuffling across the duvet, she knelt next to Victoria’s head. Her pet was still in a state of brainless, stupefied catatonia, her body limp, her head lolling, her mouth agape, dried drool around her mouth and on her cheek. “Come back up for me, Vicky, fully awake and alert,” Samantha said firmly, cradling her girlfriend’s head in her hands.

Victoria’s mouth closed, she swallowed, and her eyelids tightened, as she struggled to wake up. Samantha encouraged her with a stinging slap to the face. “Aah, ’m awake!” Victoria cried, raising and flapping her arms feebly in self-defence.

Samantha giggled, leaning down to kiss her nose. “Welcome back, my sweet little bimbo!”

Blushing, Victoria slid her hands under her back. “That was so mean,” she muttered. “I was doing such a good job of not touching myself, too, and you went and spoiled it...”

“If it’s any consolation, you got me back real good,” Samantha chortled. “I was completely unprepared for that - I was sure you were way too stupid to put up any resistance, let alone put me in trance!”

Victoria blinked, bewildered. “I did what?”

“Ohh, right, you wouldn’t remember...” Samantha frowned thoughtfully. “Maybe you didn’t even do it deliberately... Maybe it came out of your subconscious when everything else was shut down. But yeah, you used my trigger phrase, lulled me into trance. Caught me totally off guard!”

“So... we got each other?” Victoria laughed. “We put each other under... at the same time?”

“Two years of hypnokink, and that’s the first time that’s ever happened!”

Victoria sat up, wiping Samantha’s saliva off her chest. “How long were we lying here?”

Her Master blushed. “Forty minutes.”

They stared at each other for a long moment, and then dissolved into laughter.

“Now that,” Victoria spluttered, “that was dumb!”
