The car was dead silent as they all drove out to the restaurant. Paul in the driver’s seat, gripping the steering wheel nervously, while Mary fumed in the passenger seat, no doubt constructing the righteous arguments she’d hurl at Paul later that night for putting them in such a terrible situation. And then there was Ruth in the back. She’d slid into the middle seat, so that every time Paul checked the rear view mirror he would see her toothy grin waiting there for him. It was a constant reminder of just how fucked he was. 
    When she caught him looking in the rear view, Ruth opened her mouth to speak and Paul’s chest went tight with worry. Instead of speaking, however, she went into an exaggerated yawn, but her eyes were shining with delight at seeing how terrified Paul was of her. Paul cursed his luck that he was being blackmailed by someone so sadistic.
    If Mary noticed anything about the exchange she said nothing. His girlfriend simply sat watching the night pass by the window. When Paul saw the sign for the restaurant he almost cried out with gratitude that the awful drive was over. At least when they were in the crowded restaurant Ruth would have to behave herself.
    It was just as he was pulling into a parking spot in the back of the lot that Ruth finally spoke up.
    “It really was great of you to invite me to dinner, Paul.”
    Without missing a beat, Mary glared at him and mimicked her sister’s excited voice perfectly. “Yeah, Paul, it was great of you.”
    Ruth giggled in the backseat, while Mary continued to train that death stare of hers at him. At this rate Paul was afraid Mary would actually make him combust into flames just from pure, concentrated anger.
    Suddenly Ruth popped her head in between the two of them. “Come on, sis, there’s no need to be upset.” She gave Mary’s shoulder a calming pat which, if anything, only made Mary more furious. “I really do want this to be a fun dinner for everyone. I’ll be on my best behavior, I promise.”
    Mary rolled her eyes stubbornly, and Paul waited for the stream of curses to spew out of her lips. Instead, Mary forced on a fake smile, still under the hypnotic command to be nice to her sister.
    “I’m sure we’re all going to have a great time,” Mary said with a cheery voice. At this point Paul was astonished that his hypnotic conditioning on Mary was holding up so well. He’d only known Ruth for an hour and couldn’t believe that Mary hadn’t broken out of the command to strangle her sister. There were definite cracks showing, though, because even with Mary flashing a bright smile there was a large vein pulsing angrily on her forehead.
    Ruth noticed the vein and chuckled to herself. She was in on the joke, after all, and was no doubt loving the fact that her sister had to be courteous to her.
    “That’s great, Mary, but before we go in I need a word in private with Paul here.” Ruth put her other hand on Paul’s shoulder, giving him a firm squeeze.
    Paul noticed Mary jerk, her nails clawing at her dress. Through gritted teeth, she hissed, “Why do you want to be alone with my boyfriend?”
    Ruth tilted her head coyly and gave an innocent laugh. “To talk about fucking with you, of course. And maybe to finish that handjob I’d started giving him back in the kitchen.”
    As for as Paul knew his heart actually stopped right then. In slow motion he watched as Mary whirled in her seat to face them. The fury on her face was obvious, his hypnotic command finally shattered.
    “What the fuck did you just say!?”
    Mary probably would have thrown a punch, but her attention kept flitting between Ruth and Paul, no doubt trying to judge who deserved to be hit first. Ruth barely seemed to care about the look of blood-lust on her sister’s face.
    “Paul, can you handle her?” she asked, sounding bored.
    At the mention of her boyfriend’s name, Mary cocked back her fist, finally seeming to settle on who to hit. Paul let out a strangled sound and threw his hand out first. Mary launched her fist at him, but Paul’s finger planted itself on her forehead and Mary’s body slowed, her fist creaking to a halt in mid-air.
    Mary’s eyes zoned out, then snapped back to attention angrily. She opened her mouth to speak, and Paul pushed his finger harder against her forehead, hoping it would amplify the trigger’s affect.
    “Just relax, Mary,” he said, panicking. Mary really seemed to be fighting now, and if he couldn’t put her into a trance then Ruth really will have exposed the fact that he’d been hypnotizing her. “Feel my finger on your forehead and let your thoughts slow to a crawl, nice and sleepy now.”
    Mary’s fist shook, halfway to his face by now, but Mary’s eyes were fluttering. She clenched her teeth tight and managed to growl the words, “Hand… job…”
    Paul threw a scared look at Ruth, but the sadistic twin sister was clearly going to be no help. She was enjoying the show with a gleefully childish look on her face. Either Paul would put her in trance or she’d watch Mary beat the crap out of him; no matter who won she’d have a good show. Paul focused back on Mary. Thinking fast, he spoke as quickly as he could.
    “Feel the seconds rolling back now, Mary. Time reversing, everything playing backwards. Pulled back now by a powerful force.”
    An uncertain look passed Mary’s face, her anger diminishing. Her fist trembled, then slowly started to move back away from him.
    “Time keeps playing back now, like it never happened. Hear what Ruth said now—”
    Her eyes narrowed angrily.
    “But playing backwards. Slipping out of your ears and back into her mouth. Out of your memory now, since she never spoke and you never heard it.”
    Mary blinked slowly, but then her shoulders slumped as she relaxed. Paul let out a sigh.
    “When my finger leaves your forehead time will go forwards again, and everything that was rewound will be gone forever. My finger on your forehead will go back to being just a normal trance trigger.”
    His girlfriend nodded, as obedient as ever. Paul pulled his hand back and watched as Mary blinked herself away. She glanced around uncertainly. “Sorry. I— I think I zoned out for a second.”
    “No problem, sis,” Ruth spoke up, a devilish look in her eyes. “I was just talking about—”
    This time Paul clapped a hand over Ruth’s mouth, and before Mary could question it he put the finger of his other hand against her forehead. Mary reflexively relaxed. Her breath hissed out of her as she went limp and compliant. Paul pushed back against her head and guided Mary to fall back safely into her seat.
    “Just let yourself go into a nice, deep trance now, Mary,” Paul commanded, squirming uncomfortably as Ruth started licking his palm, but he refused to pull his hand away until Mary was taken care of. “Just ignore everything you hear until I call your name again. Understand?”
    “Yes Master,” Mary replied softly, her eyes slipping closed.
    Paul finally snatched his hand off of Ruth’s face, wiping her spit off against his jeans. “What the fuck was that about?” he shouted, as Ruth continued to laugh and lick the air playfully. “Seriously, she almost found out about everything!”
    “Well you should have put her into trance sooner,” Ruth snapped, talking back at him like a bratty kid. “You could have just put her into a trance as soon as we got in the car. We could have just left her in the back seat like luggage while I got to sit up front.”
    “Sure, so you could try and be terrible to her while she’s unaware.”
    Ruth leaned in and put her face next to Paul’s, uncomfortably close. Paul could smell her perfume and wondered how a girl so evil could smell so sweet.
    “Please, I’d never do that. There wouldn’t be any fun in it if she couldn’t respond in any way.” She reached out and brushed Mary’s hair back, frowning a little when her sister remained completely entranced. “It’s always a kick getting a rise out of her. Maybe if she was frozen and could still think…”
    Ruth’s eyes lit up with an evil plan.
    “Hey, I saw a hypnotist on some show make someone think they were handcuffed, even though there was nothing there. Can you make her think she’s tied up and gagged?”
    Paul shifted uneasily in his seat. “It’s something I can look into.”
    Ruth huffed impatiently. “Hurry up and do it soon then. Because if you can snap your fingers and leave Mary tied up and helpless, we can leave her in the backseat while I show you how a girl is supposed to behave when she’s in the passenger seat.” Her tongue slid out to run along her red lips. “Giving you a nice, long blow job while you drove us wherever you wanted. And Mary would watch me treat her boyfriend right while she couldn’t scream or nothing.”
    She watched him closely to see his reaction, and Paul did his best to keep a straight face. He didn’t want Ruth knowing that there was already a trigger to freeze Mary in place. It usually froze her mind too, but he knew that the trigger could be easily modified the way that Ruth was talking about. A way of trapping Mary in her head so she could watch, but be unable to do anything about it.
    “Wouldn’t that be nice, Paul? I’m sure my sister’s real stingy about going down on your cock.” Ruth grinned, but then all at once her seductive act vanished as she laughed. “Actually, I bet that’s the first thing you changed with your brainwashing.”
    The guilt on his face only made Ruth cackle with delight. 
    “You naughty boy! I bet you made her love it, didn’t you?”
    “I helped her not to feel anxious about it,” Paul said, shyly. “She had this big mental block from a past boyfriend, and I just talked her through it. She enjoys it enough on her own.”
    Ruth studied her sister, looking skeptical. “I’ve known Mary our whole lives, and she’s never liked blowing any guy before. You really expect me to believe she’s secretly liked it all along?”
    Paul shook his head. “You’ve only seen how she’s acted. I’ve been into her head. Seen the code in her mind firsthand. The way Mary talks, her likes and dislikes, that’s all just a side effect of her thoughts.”
    She gave him an incredulous look. “You think you know my sister better than her own twin does? That’s a pretty bold claim, Mr. Kinky Hypnotist.” She looked at Mary out of the corner of her eyes. “Then again, I suppose getting into Mary’s head is a pretty good cheat code. How’d you learn to do this kind of stuff to her anyway?”
    “It’s… a hobby of mine.”
    “One hell of a hobby.” She gripped the side of his seat and suddenly pulled herself into the front of the car with them, turning around to face them. Her skirt swished and Paul had a brief flash of her bare pussy before Ruth sat back against the dashboard. She was grinning at him, and he had no doubt that she’d wanted him to see her cunt.
    “We should be getting into the restaurant,” Paul said, but Ruth ignored him.
    “In a minute. I may not be able to get a rise out of Mary like this but it is kind of fun to see her so out of it.” Ruth cupped Mary’s chin, opening and closing her limp mouth like a kid playing with a doll. There was something wrong about seeing Mary being handled like that by her sister. As if she really were nothing but a doll, subject to whatever terrible ideas Ruth could come up with for her. A dark part of Paul’s heart was excited by the fear. There was no telling what Ruth could do to them, and as a fantasy it was strangely compelling. Except this was real, and he had to do something to save them.
    “I could teach you,” Paul blurted, and Ruth’s head whipped around as fast as a cobra striking. Her dark eyes studied him carefully while she closed Mary’s mouth.
    “You’d teach me how to hypnotize someone?” She tried to keep the same impassive poker face on, but Paul saw the hunger in her. He was terrified thinking of what a girl like Ruth could do with the same hypnotic skills he had, but it might be the only way.
    “Only if you promise to leave Mary and me out of it. You don’t need to mess with your sister when you can mess with anyone else. You could hypnotize all your other boyfriends. Or girlfriends,” Paul added for good measure. “Or anyone you want. Wouldn’t that kind of power be better than just toying with us?”
    Ruth leaned back against the dashboard and crossed her arms. She actually looked like she was considering it, and how could she not? Ruth was power hungry and manipulative, and he was offering her the greatest talent to accomplish any dark desire she wanted. Paul was already running the lessons through his head, trying to determine the least harmful things to teach her, when Ruth suddenly laughed, her lips twisting back wickedly.
    “It’s a very nice offer, Paul, but there’s just one problem. I want to play with Mary. I want to play with you, too. The hypnosis is an amazing spice I never expected, but it wouldn’t be the same without the both of you. Besides, the fact that I’m going to be fucking with my sister is hot precisely because of how wrong it is.”
    To prove her point, Ruth reached out and cupped one of Mary’s tits. Paul tensed up as Mary stirred slightly, but other than that remained deep in trance. Ruth squeezed her sister’s breast, slowly, enjoying it.
    “It’s hot for me that I can feel up your girlfriend and you can’t do anything about it. Even the fact that I’m blackmailing you is turning me on too.” Ruth reached up with her other hand and began playing with one of her own boobs, matching the same rhythm as she played with Mary’s tit. Paul gulped, needing to remind himself that watching this happening was wrong. No matter how hot it seemed.
    Ruth’s eyes darted down to his crotch, as if she’d been waiting. “From the looks of it, it’s turning you on too.”
    Paul tried to cross his legs in a lame attempt to hide his erection, which only made Ruth laugh.
    “You two are going to be such fun playthings,” she purred. “Don’t worry though, I’m gonna keep my promise. I won’t do anything to hurt Mary.” As she said that her fingers suddenly pinched Mary’s nipple through her dress, and her sister let out a sharp gasp of pleasure. “I promise I’m going to make her feel really good. And you too, of course.”
    Ruth let go of her own breast and reached out for Paul’s crotch. He caught her wrist, but Ruth glared at him meaningfully, reminding him of their current situation. Her threat still loomed over his head, after all. Paul cast a guilty look over to his hypnotized girlfriend, and then had no choice but to let go. Ruth smiled as she reached down and cupped his crotch, her fingers quickly finding the outline of his cock.
    “There we go. Do you like watching me feel up your girlfriend this much?” Ruth squeezed his dick, coaxing a groan out of him. “Or are you this hard because you’re watching two sisters get it on?”
    Paul’s cock twitched against his will and Ruth giggled.
    “God, what is the fascination that guys have with twins?” She kept a firm grip on his cock as she leaned closer to Mary, staring into her sister’s blank face. “Although I must say, I’m starting to see the appeal myself.” 
    Ruth watched Mary closely as she pulled her hand away from her chest and instead brought it lower, sliding it under her sister’s dress. Though Paul couldn’t see what she did next, it wasn’t hard to guess when he saw Mary jerk suddenly, eyes fluttering as she let out a happy moan.
    Ruth sat backwards between them, resting her back on the dashboard as she began to get them both off. Her eyes kept shooting between Paul’s guilty face as he tried to hide how much he liked it, and then over to Mary’s hypnotized face, which couldn’t do anything to conceal the delight she felt at the fingers inside of her. Mary started to grind her hips, smiling happily with no idea that the fingers belonged to her twin sister. In the driver’s seat Paul squirmed, feeling his cock betraying him as Ruth’s hand continued to stroke him.
    “Come on, Paul. You can’t expect me to believe this isn’t fun for you too.” She gripped his member through his pants. “Don’t you want to see me make my sister cum?”
    Paul nervously glanced out the window, and past the rows of cars he could see people going in and out of the restaurant, oblivious to what Ruth was doing to them in the car. “I’m just glad nobody can see us back here.
    That made Ruth’s fingers pause, but only for a moment. “We are a bit… exposed, aren’t we?” She tilted her head, thinking. “I guess if we’re busted it’ll spoil our fun. The smart thing to do would be to stop now.”
    Paul let himself relax, only to notice that Ruth’s hand stayed firmly on his cock. In fact, she was stroking it again, faster than before.
    He grunted. “I thought you were going to stop?”
    “I said I SHOULD stop. And I really should,” she enthused, her hand jerking him off with even more vigor. Mary was rocking in her seat now, an empty smile on her face as she panted happily from the pleasure. “Only, I really like the fun I’m having right now with you both. I suppose that means you have to be the responsible one and give me what I want.”
    Paul stared at her in surprise. “You’ve already got my cock.”
    Ruth burst into laughter. “Oh honey, you’re cock’s not that great.” Then she smiled, licking her lips. “Although, it is pretty nice from what I’m feeling, but that’s just a bonus. What I really want is for you to order Mary to respond to me the same way she does with you. That all of your fun hypnotic commands will work for me as well.
    He went pale, though it was hard to tell if it was from the shock of what Ruth wanted or the blood rushing to his throbbing cock.
    “No,” he said flat out. He couldn’t fight Ruth, but at least if the commands went through him there was still a chance he could lessen Mary’s humiliation.
    “You do what you want,” Ruth replied with a shrug. “I’m happy with what I’m doing now.” Her hand sped up and it took everything Paul had to restrain himself. Mary couldn’t be self-conscious in trance, though, and so she moaning louder, inarticulate sounds of pure need. Her breath started to hitch, which was her early warning sign that she was about to cum soon. Paul’s heart raced when he saw that. Mary was a screamer, and in trance she’d have no way of knowing to try and control herself.
    “If you don’t stop Mary’s going to cum!” He tried to check the parking lot around them but Mary’s hand stayed forcefully on his dick, stopping him from sitting up. It was hard to tell, but it looked like there would be at least half a dozen people who might hear Mary’s violently orgasmic shrieking. “You don’t understand, she- nggghhn!”
    Ruth’s hand clamped down hard on his dick, the pressure only making him realize how close he was to cumming himself. He could feel his pulse pressing urgently against Mary’s hand, like his cock was trying to use Morse code to beg her for more. 
    “Don’t worry, I know exactly how vocal my sister is when she cums. I shared the room next to her growing up and she put on quite a concert whenever she went at herself.” Ruth gazed over at Mary, working her fingers faster. Ruth herself was panting now too, like she was about to get herself off just by making them both cum. “It’s been years since I’ve heard my little slut of a sister cum. Now I really want to hear it again.”
    From under the dress Ruth’s hand must have done something new because Mary suddenly sat up from the seat, her back arching and her body going rigid as she shook and grunted noiselessly. A soft whine was hissing through her lips, growing louder every second.
    Paul felt his own hips rocking, grinding his cock into Ruth’s hand as he watched. Then he remembered that he was supposed to be stopping this, not enjoying it.
    “Please, don’t do this.”
    “Unless you want to start our date with everyone in the restaurant knowing what Mary sounds like when she cums, I suggest you give me what I want.”
    Paul clenched his fists, watching Mary’s face contorting with ecstasy while his own cock cried out with need, the pressure building up and about to spillover.
    “Fine!” he shouted, and just like that Ruth pulled her hands away. She put them up on the roof of the car, like she was trying to signal that she was innocent. Paul found himself shaking from the fear and anxiety, and the fact that he was still on the edge of cumming. He checked on Mary and found that the whine had caught in her throat, her hips still pumping into the air and making her dress swish back and forth. She frowned, her empty mind not knowing where the pleasure went. After a few seconds she let her breath out and her body relaxed, sinking back into the passenger seat. Paul relaxed himself as he watched Mary’s face melt back to a blank stare.
    He suddenly heard a wet pop and looked up to see Ruth licking the fingers on her left hand clean, humming happily to herself at the taste of her sister’s pussy. She was trembling herself, her breath hitching when she tried to talk.
    “Weirdest thing. Her cunt tastes just like mine.” She flashed a flirtatious smile at Paul. “If you’re good maybe I’ll let you compare how our pussies taste for yourself.”
    The image flashed unwanted through his head. The identical twins, naked and laying beside each other on the bed, their legs spread for him and their dripping pussies on display.
    Paul let out a heaving sigh as his cock went rigid again. “You really are a bitch,” Paul muttered.
    “You’re finally catching on,” she replied, hardly looking offended. “Now, I think you have some work to do.”
    Paul thought about trying to resist as he turned towards his hypnotized girlfriend. He could order her to ignore Ruth, to ignore any commands from him as well. Except that would still leave Ruth knowing the truth. He could try locking Ruth up in the basement where no one could hear her, but Paul wasn’t some supervillain capable of anything like kidnapping.
    Resigned to his fate, Paul reached out and ran his hand through Mary’s hair, sliding it back behind her ear. “Can you hear me, Mary?”
    “Yes Master,” Mary said in her blank voice. Then a bare smile appeared on her lips. “Master, may I please cum? I was so close and it felt so good.”
    Ruth grinned. “What do you think she’d do if she knew it was me getting her off?”
    Paul ignored her. He leaned over Ruth’s legs to hold Mary’s head, massaging her temples. “Not yet, Mary. Right now I need you to listen to me. About your sister Ruth.”
    Her face visibly darkened for half a second, but then Mary relaxed again.
    “I want you to regard Ruth the same way you regard me. Ruth can use all of the triggers I can use on you. You can show Ruth every hypnotic reaction that you are fine showing me. You’ll…” He sighed. “You’ll obey any hypnotic commands Ruth gives you just like you’d obey me. Do you understand?”
    Mary seemed to hesitate. “Do I have to?”
    Ruth grinned, nudging Paul in the ribs with her knee. “Do it. Or I’ll tell her everything.”
    “Yes, Mary. You have to obey your sister.”
    With that, Mary nodded. “Yes Master, I understand.”
    Paul considered what else to tell her, when Ruth suddenly spoke.
    “Can you hear me, Mary?”
    “Yes,” she answered quietly.
    “In your mind, you have to obey me the same way you obey Paul, right?”
    “Yes,” she answered again, barely a whisper.
    “Well, Paul’s your Master. What does that make me?”
    Mary stared ahead blankly, thinking. Finally, she said, “Mistress.”
    “That’s right. Say who I am.” Ruth was grinning with unabashed delight.
    “You’re my Mistress, Ruth,” Mary said in that quiet voice.
    “Louder.”
    “You’re my Mistress, Ruth,” she said clearly.
    “Good slut. You like it when your Master makes you cum, don’t you?”
    Paul turned and glared at her. “What are you doing?”
    She just grinned. “I’m just taking advantage of the transitive property.” Then to Mary she spoke in a firm voice. “Tell me if you like it when your Master makes you cum.”
    “Yes, I love it,” Mary replied with a smile.
    “Then you love it when your Mistress makes you cum.”
    Mary’s head shook lightly, as she frowned. “But… you’re my sister… I don’t—”
    “Confirm if everything I say is true or not,” Ruth commanded, cutting her off. “You love it when Master makes you cum.”
    “Yes,” she replied automatically.
    “You regard me the same way you regard your Master.”
    “… yes.”
    “Your Mistress is the same as your Master.”
    “… Yes.
    “You love it when your Mistress makes you cum.”
    This time, there was no resistance. “Yes.”
    “And your Mistress is your sister,” Ruth pressed on.
    “Yes.”
    “You love it when your sister makes you cum.”
    “Yes.”
    “Say that to your Master.”
    Mary suddenly turned to Paul, smiling emptily. “I love it when my sister makes me cum.”
    Paul shook, realizing the monster he’d just created. With her manipulative personality, Ruth took to controlling someone like a fish to water. He stared at Ruth, who crossed her arms smugly.
    “Not bad, right? I’ve already got her begging to fuck me.”
    That’s when Paul realized that she was wrong, though.
    “Mary,” he said, “Would you ever have sex with your sister?”
    “Of course not,” she answered, and the stunned look on Ruth’s face was priceless.
    “But, I’m your Mistress,” Ruth said lamely. “You’d sleep with me if I commanded you.”
    “No,” Mary said.
    Ruth growled and grabbed Paul’s shirt, pulling him close to glare at him. “I said to give me control of Mary.”
    “I did,” Paul snapped, knocking her hands away. “You can control her, but she still has her own limits. Everyone does. Except maybe you.” Ruth scowled, but he pressed on. “There might be some things that Mary is willing to do, but most people have a problem with incest. So if you try to command her to go through with it, she’ll refuse. I probably couldn’t get her to do it.”
    There was something dangerous in Ruth’s expression. Clearly she had been expecting to get her way, and took the obstacle in her path as a personal offense. Paul was afraid of what she’d do out of spite, but then Ruth smiled placidly and shrugged. Somehow, that seemed even more dangerous.
    “Fine, I guess I should have expected that.” Ruth adjusted herself, then looked at Mary. “Slave, fantasize about yourself having sex with me. See us really going at it, hot and heavy, cumming over and over.”
    “I already told you—”
    Ruth held up her hand, cutting Paul off.
    “Mary, do you see it?”
    “Yes,” Mary replied, an odd look on her face.
    “Do you like the fantasy of hooking up with your sister?”
    “It’s wrong,” Mary answered after a moment.
    “It sure is. But do you like it.”
    “… I do,” Mary replied meekly. “I love it when my sister makes me cum. But… I’d never really do it.”
    “I’m not ordering you to,” Ruth said with a sinister grin. “I’m just telling you to fantasize about it. In fact, every minute I want you to suddenly have a fantasy in your head of fucking me. Serving me. You can be disgusted at it or you can let it turn you on. Your choice. But for the rest of the date, you won’t be able to stop picturing yourself as you either fuck me or serve me like a submissive slut.”
    Ruth’s eyes snaked over to Paul.
    “And fantasies of me fucking your boyfriend.”
    Mary’s head snapped around, her eyes opening. Paul and Ruth both tensed up.
    “I’m not really fucking him,” Ruth quickly said, and Mary seemed to relax. “But I want you to imagine it happening in your head. I’m sure you already have ideas about what I’d do with Paul alone.”
    Mary’s eyes lowered slightly, but she remained staring up at Ruth. “Yes, Mistress.”
    “Then let’s add in fantasies of all three of us having a wild time, too. Picture a crazy, kinky orgy with every hot fetish you like thrown in. Now, run that back for me slave. What kind of fantasies will you be having all night?”
    “Fantasies about fucking my sister,” she recited, her voice empty as she spoke openly about incest. Paul watched amazed. “Fantasies about serving you, Mistress. Fantasies of you having sex with Master.” Mary twitched at that one, but relaxed as she said, “And all of us having sex together, me submissive to you both.”
    Ruth gave a quiet golf clap. “Well done. What do you think, Paul? Any sexy fantasies you want to throw into my sister’s head too?”
    Ideas came to mind, things that Paul had considered but turned down for being too much. Paul would have liked to think that he would have scoffed at the temptation, except it was a struggle not to say anything. Ruth was determined on forcing them into some strange arrangement to satisfy her fetishes, and if she was getting what she wanted then why couldn’t Paul? If they were being forced into it anyway. Still, he kept his mouth shut. Mary was the one without a say, after all, and he didn’t want to make things any worse for her.
    “Suit yourself,” Ruth said, clearly disappointed. She finally slid out from between the front seats, but reached down and gave Paul’s crotch an affectionate pet before sliding into the back seat. “Maybe once we get Mary salivating at the idea of a threesome you can finally get to stick that cock of yours in me. I’ll even be a nice Mistress and let you pick the hole.”
    “How gracious,” Paul muttered.
    Something in his tone must have pissed her off, because Ruth suddenly wrapped her arm around the seat, grabbing Paul’s chin hard. He instinctively went to pull her away, but she made a tutting sound and Paul begrudgingly put his hands down.
    “Even if you’re not hypnotized like Mary, don’t forget that I own you now. I can still tell her everything. I’m your Mistress now too, Paul.” Her fingers tightened on his jaw, and in the rear view mirror all Paul could see was the cruelty in her eyes. “In fact,” she said, chuckling, “You still need to thank me properly. Thank your Mistress for a lovely hand job.”
    Paul felt heat rising up in his face. His first impulse was to curse her out, but she was right. Ruth had all the leverage now. Besides, no matter how embarrassing it was to say that, it was nothing compared to what she had already done to Mary. He squeezed his fists and forced down his pride.
    “Thank you for the hand job.”
    “A lovely hand job,” Ruth said in a sing song voice.
    “Thank you for the lovely hand job… Mistress.”
    She let go of his chin and patted him on the cheek. “That’ll do for now. I’ll have to do a better job training you once I’ve got Mary to my liking.” Ruth sat back and put her hands behind her head. “Go ahead and wake my sister up now. I don’t want us missing our reservation.”
    It was a quick matter to bring Mary back up to consciousness, though she seemed a little fuzzy from being under for so long. “Sorry, must have dozed off,” she muttered, yawning. “Hope we’re not late.”
    “Don’t worry, Sis,” Ruth said. She leaned in and put a hand on Paul’s shoulder. “We should be right on time for our dinner.”
    Mary’s eyes instantly locked onto the hand, her jealousy rising up as easily as it always did. Paul was getting ready to say something and defuse her, but then something strange happened. Mary kept staring at them, but the hard edge to her gaze softened. Her cheeks reddened and she let a shaky breath.
    And then Paul realized that Mary was stuck in a daydream of him and Ruth having sex together, just like she’d been instructed. It was a weird sensation, knowing that your girlfriend was fantasizing about you sleeping with someone else. Sleeping with their twin sister, at that.
    It only lasted two or three seconds, and when Mary snapped out of it she didn’t yell or curse or give a snide remark. Instead, she blushed and turned away, getting out of the car as quickly as possible.
    Ruth let out a sharp laugh, jostling his shoulder “Did you see the look on her face? This hypnosis stuff is amazing.”
    “Yeah, it sure is,” Paul whispered, wondering what he’d just unleashed.
    She leaned closer, grinning. “What position do you think she was picturing us in?”
    Paul got out of the car instead of answering. Ruth followed right after, but luckily with all three of them standing in the parking lot even she wouldn’t dare try anything else. Once they were around people they should be safe, but Paul would have to think of some way out of this before Ruth had them both trapped alone at home.
    “Thanks again for inviting me, Mary,” Ruth said loudly, relentless. Paul saw Mary scowling but she kept her eyes forward, not taking the bait. “It gives me a chance to show off this new dress. Don’t I look great in it?”
    Mary gave her the barest of glances. “Yeah, you sure look—”
    She suddenly trailed off and did a double take. Mary stared back at her sister, her eyes widening slightly. Her face had a look of shock on it, but her cheeks were burning bright red.
    “What’s wrong, sweetie?” Paul asked. When he got a good look at her, though, Paul recognized the look. The same one she had in the car when she was lost in the fantasy. Mary’s stunned expression was because she was day dreaming about fucking her sister.
    Mary came back to herself and spun around, quickly marching off. “It’s… it’s cold out. I’ll meet you in there.” She hurried off before Paul could stop her.
    Ruth was laughing as she caught up with him. “Must have been a hot fantasy to run off like that. She even left me alone with you.”
    “Well, it’s just a guess, but I don’t think she’s used to thinking about fucking her sister. Not everyone’s into incest.”
    “That’s just because it’s not the mainstream kinky thing to be into,” Ruth said dismissively. “It’s hot when you give it a chance. And Mary. Well, let’s see how she stands on incest after she’s fantasized about it all night.”
    Right then, Paul knew he’d made a mistake giving Ruth that kind of power. She’d seemed impulsive, reckless, but what she said now was insidious, because it could really work. Make someone obsessed on an idea long enough and they’ll open themselves up to it. Mary had a limit on incest, but it wasn’t strong enough to stop her from thinking about it. There were cracks in the limit, and if Ruth hammered at them all night then she might really be able to order Mary to fuck her. To make things worse, Paul felt himself getting more turned on too by the thought of watching the sisters fucking. If it wasn’t for Ruth’s evil plans, he probably would have been all for the incestuous threesome she wanted.
    Ruth took his hand and Paul shivered, realizing he was getting hard again. “Come on, lover boy. I think this is going to be a date we’ll never forget.”
