Grocery time, probably

With her head now running a bit calmer Cathrin figured it might be a good moment to do the grocery. She could only do it right after she came, as otherwise she run into the risk of getting too horny before she came back, and that might lead to her begging strangers for dick again. At least the last guy was kinda nice, even though he did make her feel like a slut sucking him off in the parking lot. Cathrine checked her fridge for what was missing, and once again got reminded how thorough these changes were. She could no longer gain weight, and the constant arousal and orgasms had driven her daily calories usage up to around 3400. She had been counting before she had the unfortunate event of meeting Sven to get rid of extra weight, now she was counting to not starve to ****. While her boobs were literally full of fat, her body refused to touch that, those apparently just had to stay at their ridiculous size. As he had however given her the "perfect" body otherwise, with not an ounce of fat too much, she was **** to make sure food was always readily available.

Cathrin got rid of her panties and grabbed her coat. She just had to go naked underneath since he had decided for her to be a nudist. She still remembered the moment he had done it in one of his creative moments very vividly. Sometimes he didn't just simply program her brain to do what he wanted, but instead **** her through punishment to make her involuntarily obedient. Probably he just loved to see her fight his commandments and fail. He had urged her to leave naked, yet of course she refused. But when she had her clothes put back on, she hadn't even managed to make it to his door. Suddenly all those clothes had felt like razorblades on her skin, and every step felt like being flayed alive. Under screams she got rid of them while he was laughing, just to realize it was once again all in her mind. She later experimented, and learned that the more she put on, the worse it became, especially if she tried to cover her tits. However as he apparently had written "clothes" her boots didn't count, and neither did the cloak. However the latter still felt uncomfortable, as it was hiding her tits. Or at least it tried to, as confirmed by the gigantic bulges in it in the reflection in the mirror. They left little to the imagination.

She always felt like pervert walking around the outside all naked underneath. Always afraid her cloak would accidentally open, revealing her nudity. Her long boots were perfectly hiding the fact that she wore no pants, but should those front buttons ever give up on her, her massive rack would just flood into the world for everyone to see. Yet she was standing in the store, pretending nothing was out of the ordinary as she had to, trying to decide which cookies to get. The people around her secretly glanced at her, especially males, but she could hardly blame them. They must take her for a porn star, and she definitely had the looks. She felt her arousal slowly returning and figured she had probably like an hour left before it would overwhelm her again. And the rubbing of the fabric on her big, relentlessly erect nipples certainly wasn't helping. She probably should just grab whatever to not waste too much time, she decided. When she got lost in the heat the last time, it was because she got stuck at the checkout for over 30 minutes, till she was desperately trying not to rub her clit under the jacket. She finally lost it when that hot guy flirted with her before she could get into her car. He did have a nice cock though, she remembered, and immediately regretted that thought.

A jolt of pleasure hit her pussy, as programmed whenever she thought of servicing big hard dicks. She immediately tried to focus on her mantra, but the loop was already heating her up. Pleasure lead to thinking about cocks, thinking about cocks lead to more pleasure. She knew she could escape this loop, if she would just focus on something boring, meaningless, unsexy, and especially not...
Sven's...
big...

It felt like a wildfire spreading through her body, setting everything aflame in an instant. Just a second of that image of Sven's 20 inch boner ignited every erogenous zone in her. Her eyes rolled back as she desperately tried to not moan aloud, and even harder to not think of his... cock... again. Her knees buckles while she desperately tried to keep that image from flashing into her mind, how she sucked on it, pleasured it. Losing the battle she sunk to the ground, her pussy dripping already, getting ready to take it in even though it wasn't around. She was just about to go wild on herself right there in the store, when suddenly a voice ripped her out of her arousal loop.

"Miss? Are you ok?" A hand touched her shoulder, and she opened her eyes. A young guy, probably doing a colleague side-job at the store, stared at her worried.
"I... think I fainted." she lied. Her programming would have forbidden her to speak the truth anyway though. He tried to help her up, but with her rack the required way was to get on her knees first, get her torso up straight, and then lift her assets with her legs.
He probably has a nice cock... inevitably went through her mind when she was at eye level with his crotch.
"Do you want me to call an ambulance?" the guy named Marc according to his tag asked as he tried to assist her to get up. The damage was done though, and the only thing a doctor could do now to get her back on track was to shove something big into her pussy, till the explosive reset calmed down her libido again. His eyes lingered on her concealed rack for long enough to let her know that he definitely liked what he saw. A much better and quicker solution...
"D-do you have a bathroom I could use?" Cathrin tried her best to not let her arousal be too audible in her voice. She knew the answer already, she had been buying here for years.
"Uh..." Marc stammered "Only for employees... but I think I can make an exception." Marc looked around but apparently no manager was in sight, so he decided to show some initiative. "You sure you are ok?" he asked once more as he lead her to the back.
"Yes just... bad night." her excuses were incoherent, as was her mind, desperately trying to evade thinking about sucking that guy's cock dry just yet. He however was apparently too charmed by her... personality to put too much thought into it. And when they finally arrived at the single person bathroom, she looked into his eyes, bit her lip, and with convincing amounts of sex oozing from her voice she asked:
"Could you come in with me? Just in case?" He got the hint.

Not even a second after the door was closed she jumped him, pressed him against the wall, and planted a seductive kiss on his lips. She could see his dick raising fast when her coat fell to the ground, and two almost basketball-sized tits jumped into reality. He certainly had never seen some this big, and was more than willing to let her take the lead and sink his hands into them. She could have probably just let him squeeze them and send herself over the edge with her trigger, but it had been a week since she had a real cock inside her, and her body was programmed with a burning desire for them now. So she shoved him onto the toilet seat and both equally eager to get ready, they together pulled out his swelling cock. There was probably no reason to warm him up anymore, but then Cathrin got these blowjob-lips, so she put them to good use. A nice 7 inches were masterfully teased by her very skilled tongue, turning his dick into a bar of steel, and switching his brain off in the process under groans of pleasure. Once he was sufficiently throbbing, Cathrin moved up and climbed into his lap.

"D-don't we need... p-protection?" he stammered, breathing heavily.
"Don't worry, I am on the pill." she lied. In reality Sven had made her unable to get pregnant as he just loved to cum inside her. "You can fill me up to the brim, stud. It's fine." He didn't decline the offer. Feeling his dick slowly sink into her pussy filled her with a bliss she had not been able to feel before Sven had changed her. And yes she knew it was all artificial, a programmed reaction to condition her, but it still felt incredible every single time. She grabbed his head and buried his face between her massive knockers, then started riding him. Having a cock inside her again felt like an addict getting a shot after being denied for days, and with his greedy hands exploring every inch of her vast tit-flesh, she was surfing on the waves of pleasure that rocked her body and fried her brain. He didn't last long. When she felt him shoot his load into her slit barely three minutes after they started, one thought of sucking off Sven made her explode with him. Losing all control of her body she fell forward, twitching, moaning, trying to muffle as much as she could in her own tits, and conveniently he tried his best to hold her when he felt her slipping downwards.

When she came back to reality, she was between his legs, her face resting on his smeared still semi-erect dick. She felt cum running from her pussy down her legs onto the floor, and the strong odor of what they had just done was unmistakably in air. Although she hated what her libido did to her, she felt like she had handled it much better than last time. At least no one saw her uncontrollably fucking a random guy.
"Damn, you cum like crazy." he eventually broke the silence. Cathrin, now once again in control of her brain just put on a fake smile. "Can I have your number?" he asked.
She pondered for a moment while she got up and cleaned her face and clit with some toilet paper. Usually she wouldn't, but considering her state, it might actually be good to have a fuck-buddy she could call if she needed to.
"Give me yours, maybe I call you when I am in the mood." she said with a smirk "Chances increase if you don't tell anyone what happened here." He nodded frantically and had it on paper in record time. "Oh and wait a minute after I leave. Don't want anyone to ask question." She slipped her coat back on, and moved back into the store carefully. No one seemed to have noticed. She decided for the white chocolate cookies with nuts, got the rest on her list, and headed back home before any further accident would happen.
