Ben stared in stunned disbelief at the man’s struggle; but then the heavy musk of pussy prompted him to turn to Sarah and Kelli, who frolicked naked on the floor beside him. He couldn’t help but watch them... and even found himself comparing them... and noted that Kelli’s boobs were bigger and fuller than Sarah’s and Kelli possessed a nicer, rounder butt.

“Take that in your bedroom,” he told Sarah when they happened to make eye contact, but Sarah ignored him.

“Why is she ignoring me?” he asked the man, turning back to him.

“During this state, she’ll only respond to the person she imprinted upon,” the man replied.

“What the hell is that supposed to mean?” he asked.

“After she breathed in the drug, she imprinted on the first voice she heard.”

“Why does she seem distracted... and keeps on glancing at the door?” Ben asked.

“She’s waiting for her boyfriend, so she can spray him with the drug.”

“But I’m her boyfriend... and I’m the one holding the bottle,” Ben countered, but when the man didn’t respond, Ben asked; “Are you saying she doesn’t even know I’m standing in front of her?”

“If it weren’t for her sexual need for her sister right now, she’d be visibly conflicted. Undoubtedly, you are causing her confusion; but thanks to her sister; she’s managing.”

“Tell me what can be done to fix this!” Ben demanded in anger.

“While she’s still in this malleable state, I can add more to the command she’s under to alter the meaning.”

“Then do it! I don’t want her stressing!”

“Sarah?” the man said; immediately drawing Sarah’s attention. Kelli continued to feast on Sarah’s pussy. “Your boyfriend didn’t use the door to come inside. That means you can’t spray him given he’s already inside your apartment.”

“I can’t spray him?” Sarah asked in a soft voice.

“That’s right, you can’t spray him because he didn’t use the door,” the man told her.

Ben then watched in relief as Sarah nodded before returning to her sister’s pussy.

“What’s your name?” Ben asked the man.

“Jonathan Spencer.”

“Alright, Spencer... what did you do to them?”

“I sprayed them with a drug.”

“I gathered that... I want to know the specifics,” Ben snapped.

“When a subject breathes in the drug, it immediately places them in this malleable state. Once imprinted, the imprinter can alter the way the subject thinks, feels, and behaves.”

“Then let me start with a rule... you cannot say or do anything to harm me or the girls.” The man nodded. “And you must do everything the three of us tell you to do,” Ben added.

The man struggled... but only for a few moments.

“I noticed you struggling; explain.”

“It is only natural for the subject to struggle if they don’t like a command... but no amount of struggling can change the outcome.”

“List the commands you placed on Sarah,” Ben commanded.

“That she cannot run away from me or harm me... or raise any kind of alarm. That she’s bisexual... and always found her sister to be sexually attractive. That she is deeply in love with her sister... and that she would admit her attraction towards her... and act upon it.”

“You actually altered her memories?!”

“Yes, the command shuffled through her memories and rewrote her history to support the command. All the times she saw her sister naked after puberty, where she felt nothing but sisterly affection, she undoubtedly remembers now as being sexually turned on.”

“What did you do to Kelli?” Ben asked.

“I told her she no longer felt anything towards her boyfriend, but instead loved me absolutely and unconditionally. I also told her that she worshipped the ground I walk on and that she was bisexual and deeply in love with her sister; have always been sexually attracted to her; would admit to these feelings; and act upon them.”

“Is there any way I can prevent Kelli from being in love with you?”

“Yes; but only during this malleable state. You can transfer how she feels about me to someone else.”

“How long will she be in this malleable state?”

“It’s been about twenty minutes since she’s been dosed, which means she has about ten minutes left.”

“Then do it! Transfer how she feels!”

“Who is to be her new benefactor?”

“Her boyfriend,” Ben replied.

“I’ve already commanded her not to feel anything for her boyfriend, so that won’t work.”

“Then we’ll ask her to select someone else,” Ben replied.

“Her benefactor must be present.”

“Fuck! Then make it her sister!” Ben snapped.

“She already feels this way towards her sister.”

“Are you saying it’s either you or me?!”

“Yes, those appear to be the only two options.”

“Why can’t I simply re-spray her and give her new commands?”

“If you wait until she comes out of her drug induced state; then all the commands I gave her become permanent. Re-dosing her will only allow you to add to her existing commands, and although it’s true you could alter the meaning... it wouldn’t be enough to return things to normal.”

“Give me an example of what you’re talking about!” Ben demanded.

“If you command a girl to be constantly horny; she would be constantly horny which means you basically turned the girl into a nymphomaniac. But if you re-dose her, and then command her to be constantly horny to one specific person, she’ll no longer be a nymphomaniac, but a very horny girl for one specific person.”

“So, if I don’t take advantage of this opportunity while Kelli is still in this state, then I’ll doom her to love you for the rest of her life.”

“Not only love; but worship the ground I walk in... I basically turned her into my love slave.”

“How many doses are left in this bottle?” Ben asked.

“None. You used the last one.”

“What about the bottle in your pocket?”

“There are two doses left,” the man answered after a moment of struggle.

“Without spraying me, hand the bottle to me,” Ben commanded.

Once Ben had the bottle in his hand, he glanced back at the girls. They were still passionately eating each other’s pussy and Ben could feel himself harden at the sight of them.

“Alright, Spencer... transfer everything you commanded of Kelli to me.”

Sarah felt like she was trying to navigate herself through heavy fog when she heard the man tell Kelli that she no longer felt anything for him; but instead felt it for Ben. She tried to understand why the man would say this because she remembered Ben was her boyfriend.

“That’s right, Kelli... everything you once felt for me is now how you feel about Ben,” the man re-stated; and Sarah saw Kelli look at Ben like she was seeing him for the very first time; and it was that exact moment when she snapped out of her drugged induced state.

“Asshole,” she muttered; picking herself up off the floor.

“Sarah?” Ben said.

“Yeah, I’m back,” she replied without looking at Ben. She was way too busy shooting daggers at the man with her eyes. Then she hauled off with the intent of slapping the man, but...

“Huh?” she responded; shocked... and then she remembered she couldn’t harm the asshole. “This is crazy!” she screamed, and only then did she start to feel vulnerable and embarrassed about being naked.

“I love... Ben?” Kelli asked; prompting Sarah to turn back to her sister.

“Yes, everything you used to feel for me... your love, your desire, and how you worship the ground I walked on is now how you feel towards Ben,” the man replied.

Sarah turned to Ben, who looked defeated, and she remembered how he hadn’t had a choice.

“Sarah?” Kelli called to her, and it was their overwhelming love for one another that wouldn’t allow them to hurt one another.

“It’s alright, Kelli... he’s yours now,” she answered, wanting Kelli to know it was okay.

Kelli remembered how painful it was to fall out of love for her boyfriend, but this was much harder, given the intensity of how she felt, until she began to feel the shift in her feelings towards Ben. Then Kelli didn’t want to hurt Sarah; remembering the few times she stole her boyfriends from her in the past... but once Sarah gave her blessing; making it alright to feel the way she did towards Ben, everything suddenly became wonderful.

Then Kelli suddenly snapped out of it; looked down at herself... shot a glance at Sarah... and then turned red with embarrassment.

“Fuck!” she cried out as everything came crashing down on her. Kelli shot the creep responsible an angry glare but because of how powerfully drawn she felt towards Ben; her anger dissipated.

“Are you back?” Sarah asked her.

“Yeah,” Kelli replied, and she found herself comparing the different levels of love she felt between Ben and her sister.

“Welcome back, Kelli,” Ben greeted her, and Kelli couldn’t suppress a blush and a smile.

“I... I love you. I love you more than anything else in the world,” she declared; gazing at Ben with adoration.

“Sis?” Sarah called out to her.

“I love you too, Sarah,” Kelli quickly added; hoping Sarah would understand.

“I know... I love you, too. Let’s grab our clothes off the floor and go put them on in my bedroom.”

Kelli hesitated only for a moment before she picked her discarded clothes off the floor; shot Ben an embarrassed smile; and then rushed off with Sarah.

“I’m sorry I love Ben more,” Kelli whispered.

“Don’t apologize for something that isn’t your fault,” Sarah replied; and then embraced her for a moment; giving Kelli a tight loving hug.

“It’s so weird... I know our memories have been tampered with, but I can actually remember all the times I wanted to be with you,” Kelli announced.

“I know what you mean,” Sarah giggled.

“And Ben is a fucking God! He’s just so fucking incredible! I can’t wait until I get the chance to worship every inch of him!”

“And it obviously doesn’t matter to you that this is artificial as well,” Sarah replied.

“Not when it feels so incredible,” Kelli responded. “But how can you given up your boyfriend so easily?

“Because I’m in love with you, Kelli... and what I felt for Ben prior, pales in comparison.”

“Ben, I love you so much,” Kelli decreed as she approached.

“Then give me a hug,” Ben responded; taking Kelli into his arms. He could feel himself responding as they pressed their bodies up against one another.

“So, who’s the asshole?” Sarah asked.

“His name is Jonathan Spencer,” Ben replied.

“I know that much... I meant what’s his story?” Sarah asked; rolling her eyes.

“I purposely waited till your return, so I haven’t started the questioning.”

“Alright, Spencer,” Sarah snapped. “How do you know conflicting commands won’t work with a new dose?”

Ben smiled; this proved Sarah overheard their earlier conversation.

“I’ve tried it a few times, and with each time, after their initial struggle, the girls rejected the new commands in favor of the original ones.”

“Ben?” Kelli whispered into his ear. “Let’s go to Sarah’s room so I can worship your body,” Kelli stated.

Ben glanced over at Sarah but saw that she was preoccupied with Spencer.

“We would have been fucking sex slaves if it hadn’t been for you,” Kelli proclaimed, while she reached down and began to rub his hardened cock through his jeans.

“Be patient,” Ben responded to Kelli; who pouted in response.

“Where did you get this shit?” Ben asked, holding up the spray can.

“The military were sponsoring a chemical trial for psychedelics at the pharmaceutical company I worked at... and once I realized what the drug could do, I confiscated their inventory of sixty bottles and altered their notes.”

“How many bottles do you have left?” Sarah asked.

“Forty-three.”

“Did you share this with anyone?” Ben asked.

“I sent ten bottles to my nephew for his eighteenth birthday.”

“What’s his name?”

“Joel Spencer. His mother never married.”

“I’ll want the address later,” Ben stated; horrified to think what an eighteen year old kid would do with a drug like this.

“What about the formula?” Sarah asked.

“I sent it to a friend in California.”

“Is he a chemistry buff or something?” Ben asked.

“He isn’t, but his son is majoring in bio-chemistry at a prestigious college out there.”

“Will anyone miss you?” Sarah asked.

“My love slaves... and maybe my nephew. I doubt my niece will.”

“Slaves...?” Sarah challenged.

“What else would you call them?” Spencer replied.

“Look whose back... the asshole,” Ben responded.

“How many girls have you enslaved?” Sarah asked.

“Thirteen... well, fifteen including you two... but now I only have five left.”

“Explain,” Ben commanded.

“I began pairing them off.”

“And this has allowed you to release them...?” Sarah asked.

“Yes. I make it standard operating procedure to turn all the girls bisexual; that way they can make love to one another whenever I’m not around. I learned that if you pair the girls up... give them another dose... and then amplify their lesbian desires while deadening their heterosexual desires; works like a charm.”

“So, they still love and desire you... but not nearly as much as they love and desire each other,” Sarah clarified.

“That’s correct,” Spencer replied.

“I should kill you,” Sarah commented.

“Nobody is going to kill anyone, Sarah,” Ben interjected; drawing a glare from Sarah. “Anyway, how long ago did you send those bottles to your nephew?”

“Just a few weeks ago.”

Kelli was growing more and more anxious with each passing second. If Ben didn’t take her to Sarah’s room soon, she was going to throw herself down on her knees and beg him. Her pussy was soaking wet... and as much as she loved her sister’s tonguing earlier, she desperately needed Ben’s cock.

“Ben?” she heard Sarah draw her ex-boyfriend’s attention.

“What?” Ben snapped, and Kelli wondered why he was angry with Sarah.

“Go fuck Kelli.”

Kelli blushed as Ben turned to her. Yeah, she was horny... hornier than she’d ever been before... but was she really that obvious?

“Fine,” Ben replied.

“But leave the bottle on the counter.”

“Just don’t use it on him,” Ben warned.

“Whatever,” Sarah replied as Kelli pulled Ben’s hand and headed off down the hallway.

When they reached Sarah’s bedroom; Kelli didn’t hesitate to strip off her clothes again; and without the slightest shyness, she proudly stood before Ben so he could feast his eyes on her body.

“Do you like what you see?” she asked, smiling. Pleased with the desire she saw in Ben’s eyes.

“I love what I see,” Ben responded, and then he stripped.

Kelli gasped at the sight of Ben naked; and then in worship, she kneeled down in front of him... absolutely mesmerized with the size of him.

“No fucking wonder Sarah kept you!” she cried.

“Glad you approve,” Ben laughed as then he stooped down and picked her up... and threw her on the bed.

Kelli remembered Sarah telling her how much Ben loved taking her ‘Doggy,’ so she quickly got herself on all fours and presented her sexy ass to him.

“Fucking incredible,” Ben declared, and she nearly came when Ben nudged her wet petals apart.

“Ohhhhhhh fffffuuuuuuuuccccccccckkkkkkkkkk,” Kelli cried out as Ben penetrated her; and she proceeded to explode to the first of several orgasms.

Sarah restlessly paced the living room in front of Spencer. She could hear Ben and Kelli fucking, and only because of her desire to be with Kelli, did she want to join them.

Sarah noted with amusement that she wasn’t the least bit jealous of Ben; despite him having the upper hand. Was it because she felt secure in the love Kelli felt towards her that allowed her peace of mind?

Sarah also noted that she didn’t feel the least bit of anything for Ben, now that she loved Kelli. Did this transformation mean anything? Why was she now favoring her lesbian side more so than her heterosexual side?

Sarah glanced at the spray can as she retrieved her laptop off the kitchen counter. Then she sat down next to Spencer and began drilling him about his harem. First, there was Linda Thornton; a rich girl, that financed his operation. She was in her mid twenties and a minor celebrity of sorts, so she knew of her. Linda was also a hottie... and her pussy recognized this; based on how wet she was getting from the prospect of meeting and eventually being with her.

“I’m surprised you didn’t marry her,” Sarah commented after Spencer talked about her.

“Didn’t need to,” he replied. “Linda has been more than happy to provide a home for all my slaves given she’s in love with every one of them... and she’s even happier to spend her huge allowance providing for all of us.”

“So, in addition to Linda... you have four other girls?” Sarah asked.

“Yes. I nabbed two girls right off a college campus... another girl had been a hostess at a fancy restaurant... and the last girl was a model. They all keep our sexual relationship a secret and with the exception of Linda... and one of the college girls... they maintain their normal life.”

The more Sarah learned from Spencer; the angrier she became, as it bothered her that she couldn’t hurt him. It also bothered her that Ben might cut him loose and she couldn’t stand for that because Spencer deserved to be crucified for what he had done.

Sarah got up and began pacing again... and then picked up the spray can off the counter. She remembered there were two doses left and wondered if she could pull this off.

“Is there a time limit between dosing someone?”

“No,” Spencer replied, eying her suspiciously.

Sarah told herself that she appreciated that Ben saved her and Kelli... and nor did she feel anything bad about Ben making Kelli love him... but what she didn’t want was Ben calling the shots from this point on.

Sarah looked over at Spencer.

“Tempting, isn’t it?” he commented.

“Keep your mouth shut and stay right there,” she commanded; knowing Spencer had no choice.

Sarah walked down the hallway towards her bedroom; and then paused outside her door. She could hear Ben grunting and Kelli groaning. Slowly, she opened the door and felt relief that they were both facing away from her while Ben fucked her sister from behind; just like Ben used to fuck her.

“Harder,” she heard Kelli whimper as she quietly approached.

Ben must have accommodated her sister because she cried out in ecstasy; and when Kelli’s eyes reopened, she saw her in the mirror’s reflection.

“Sarah!” Kelli cried out just as Sarah blasted the first dose into Ben’s face... and then the next dose into her sister’s face.

“You love fucking each other,” Sarah commanded; triggering the imprint.
