Leah unwittingly joins beta testing

The door to my apartment squealed as I pushed it open. All the lights were off, so I knew Leah wasn’t home. I breathed a sigh of relief and dismay at that.

Leah could wait, though. I still needed to make a few quick tweaks to the software.

Sitting down in front of my computer again was not an enticing prospect. To be honest, replaying the memory of Hana in her mindless trance had my jeans feeling a bit too tight. Taking care of that issue seemed much more palatable. However, I knew if I got myself off, I’d get that post-orgasm regret, and I had no desire for that yet. So I started typing again.

My fixes were minor. I added a right-click menu with all the bells and whistles ordinarily present in a file explorer, like copy, paste, view/edit properties, etc. I had no idea if the commands would actually work, but it would be nice if they did.

I also reworked the filter/tag system slightly. I had already foreseen possible issues with the standard setup. The default setup had used AND logic. I simply changed it to a more “advanced search” type of layout, which allowed for searching groups of terms under AND, OR, and NOT Boolean logic. The option to modify the “weight” of specific tags also seemed like a good idea. My mind wandered off task to fantasize about using the tags HAPPY and HORNY on my cute roommate. Through the haze of arousing daydreams, I wondered to myself. “What if the happy memories are stronger than the horny memories?” Naturally, adding a multiplication factor to the weight of the “horny” option seemed like a reasonable fix.

Lastly, I added an option to save preset tag searches and sorting schemes so I wouldn’t have to start from scratch forever.

By the time I finished the programming, it was getting quite late. I figured Leah must have had a girls' night out or something. I knew she wasn’t currently dating, and she never studied late, which narrowed down her late-night activities quite a lot.

With nothing else to do with my coding and no test subject in sight, I instead took a second look at the AI subroutines in my software.

“What the hell!” I exclaimed. I was dumbfounded by what I found. The AI’s code had expanded exponentially. Somehow, whoever originally programmed it had given it the ability to adjust its code. The code might as well have been gibberish to me. I did recognize two things, though. It accessed the video and audio outputs to the VR headset, and it somehow connected to a data storage device using the VR headset’s wiring. Diving into the run logs from Hana’s test, I could see the headset moved 4GB of highly compressed data out of a 10TB hard drive and onto my computer. When I applied the sleep filter, 500MB of data was moved back. All 5GB were transferred back at the end of the test.

Suddenly, I heard the front door unlock and squeal open. I hurriedly closed all my files without realizing how unnecessary that guilty reaction was. Leah wouldn’t be able to tell anything about my code.

“Hiya Mac! Still working on geek homework?” She joked while leaning against my open doorway.

Leah was dressed to the nines and looked exceptionally hot. She had on a black choker, high heels, and a short, silky black dress that showed lots of her curvy cleavage. God, I wanted to see her in my bed with that outfit partially removed.

“Hey, Leah,” I responded while trying not to stare too much. “Yeah, it seems like that’s all I ever get to do now. Looks like you had a fun night, though.”

She recalled all of her activities with her girlfriends from the evening and night. All the while, I just half-listened. My preoccupation lay more with the VR helmet beside me. When she was done talking about her night, I gestured her over to my computer.

“So, when I ran out of the house this morning, it was because your photo selection woes gave me an idea,” I explained. “Now, I’m almost done making a program that analyzes your reactions to photos and then automatically lists them in order according to which ones elicited the best response.”

Leah sat down awkwardly on the corner of my desk beside me. “No way! How will that work?” She replied, intrigued.

“Most likely like absolute shit,” I said with a laugh. “The AI, or more accurately machine learning stuff, is really hit or miss. Regardless, would you like to test it out?”

“Yeah, sure! What do I need to do?”

I connected her smartwatch to my computer and handed her the VR headset, just like I did with Hana earlier. She took the headset and walked over to sit with crossed legs on my bed before putting it over her head.

The data started rolling in almost instantly this time. The AI had clearly learned something from Hana. The only response from Leah was a light squeak, and then her body relaxed.

With the overflow error disabled, it took about 5 minutes for all the .gifs to load into my interface. If the AI worked correctly, her memories would be sorted by default according to their weight. IE, the first .gif should be the most defining memory for her personality… or at least that’s what I hypothesized.

I opened the first file. It was low quality, but that’s to be expected when 10TB of data is rapidly compressed down to mere GB. I recognized the memory immediately. She was in the hospital at the bedside next to her grandmother. I wasn’t in the room at the time, but I knew this was moments before she passed away.

I right-clicked on the file and opened the properties. The properties listed several tags with high-weight values. Bittersweet, Nostalgia, Love, Grief, and Mentoring topped the list of tags. Under notes, most of the info looked like gibberish. It was an incoherent amalgamation of sensory inputs, internal dialogue, and etc. The AI could probably learn to organize the memories into useful info better if I helped it with examples. Either way, it was clear that her grandmother was passing on some final words of wisdom with her final breaths. It was apparent why this was Leah’s most important memory.

The bittersweet images almost made me second guess, playing with Leah’s mind, but I managed to shake off my pesky conscience. With determination, I typed the word LOVE into the filters. The list of files shrank significantly, though some of the top items remained in their places. That wasn’t surprising, though. I assumed love would have a pretty strong weight within the filters, especially since it’s such a widespread idea.

To narrow it down some more, I added AND ROMANTIC to the filter. That caused all the files to be rearranged. I could see an image of her ex-boyfriend at the top now. To fix this, I added the tag AND MAC. To my dismay, this narrowed the memories to just a few dozen. I also sadly noticed her ex-boyfriend was still present in the top memories. Going back to the filters, I added all the names of people she had fallen in love with in the NOT filters.

A dozen files remained. I scrolled through a few of them. They were from times when I did something she considered very sweet, other than a couple when I had some deep conversations late at night. I recognized all of them. Reading the properties of the files, I could tell they were all missed opportunities. Any one of these 12 memories was a crossroads where I could have made a move and shifted our relationship to something bigger. It was almost depressing to see. The spark had been there a handful of times. A couple of times, there may have even been a strong flame, but my inaction had long doused it.

With shaky hands, I hit the EXECUTE button and sent only those 12 files back to her brain. I couldn’t fathom how she would act with all her memories, aside from those filtered by “romantic love, for only me,” removed.

I stood from my desk chair and sat beside Leah on the bed. With trepidation, I lifted the VR helmet off her head. She maintained a sexy blank stare for a moment before recognition and awareness flooded back into her.

“Oh, Mac, I think I lost track of what we were talking about! Please forgive me,” She leaned her head on my stiffened shoulder and tenderly embraced me as she sweetly apologized. “I think I got lost in your eyes, Mac.”

I suppressed a laugh at the cheesiness of her not-so-subtle flirt. My emotions were a mess. I felt burning arousal at the fact I clearly altered her memories. I also felt my suppressed yearning for her bubbling up while my anxiety flatlined. With a sigh, I relaxed into her warm embrace.

“T-that’s ok; I was lost in y-yours too.” I stuttered lamely.

In her current state, my lame reply had a profound effect, though. With only a dozen memories in her head and all of them pertaining to love and me, there was nothing to stop my words from making her swoon.

“I’m a little embarrassed to admit it, but I think I’m in love with you, Mac.”

Her words made my heart flutter, but they also intrigued me. I was surprised to hear her claim she was embarrassed. With a quick eureka moment, I realized that the memories pulled back into her brain still had other tags attached. Embarrassment, attraction, and other thoughts and feelings would still be present as a result. I’d have to make a tool to bulk edit the weights of tags within memories to fix the oversight.

“I love you too, Leah,” I lied. In reality, I knew my feelings were closer to lust and possessiveness.

She simply blushed and buried her head into my chest. I placed my hand beneath her chin and guided her lips to mine. Leah’s soft lips met mine, and we gently made out. I could feel the love she put into her kiss. It was soft, subdued, and lovingly passionate. However, there was very little lust and no desperation. It was clear that very little arousal and attraction were present in her filtered memories.

She didn’t object to me showing my lust, though. She didn’t react to my tongue or my roaming hands on her body. Out of curiosity, I grabbed her round ass beneath her dress and squeezed. She didn’t react. I stopped making out with her. Getting bolder, I hiked her dress up to reveal her black lace panties. She let me spread her legs apart and run my finger along her crotch. She shivered slightly at the sensitive contact, but her loving gaze remained unfettered. Her body showed zero signs of arousal or concern.

It’s like we were dancing to two separate tunes. I knew I could fuck her, and she wouldn’t have the ability to distinguish it from the loving, flirty, PG13 fun we had initially. I wanted her participation, though. She couldn’t participate or react to my actions because her life experiences were so limited.

I hopped back up on the bed beside her. “Leah, this is a weird question,” I asked, “but can you tell me your life’s story?”

“Of course, sweetie!” She replied lovingly, “Let’s see… I was born, I grew up with you and went to school with you. When I turned 18, we stayed out late at night talking after my birthday party, and I first realized I loved you, then…”

“Ok, OK, wait,” I interrupted her excitedly. “You said you were born. Who are your parents? What can you tell me about them?”

She turned to face me with her seemingly permanent smile still beaming. “They are the two people who conceived and raised me, of course! I don’t know what else to tell you about that, love.”

“So, I guess you have a basic understanding of The framework of your life,” I mused aloud. “What about education though? What is 5+7?”

She almost imperceptibly tilted her head. I guess one of her 12 memories added a slight amount of confusion to her very limited emotional toolbox.

“I don’t really know what you mean, but I do love listening to you talk.” She replied cluelessly but sweetly.

“Hmm,” I wondered, then raised my hand. “How many fingers am I holding up.”

“Five!” She answered.

“That’s right! If I held up two more on my other hand, how many would I have up?”

“Seven!”

I’m not a brain surgeon, but it sounded like the removal of memories heavily impacted the prefrontal cortex, while other parts of the brain still remembered the basic concepts of life and education. The removal of memories, in short, mainly impacted higher-order cognitive processes. Leah can do basic math with tangible objects but can’t conceptualize it. She probably understood that I was grabbing her ass, but she couldn’t use any logical reasoning to develop a reaction to it.

Without asking, I grabbed the VR helmet and shoved it back on her head. I didn’t see any purpose in asking permission. She would have loved the idea regardless.

As she relaxed and laid back on the bed with her dress still hiked up, I went back to the computer.

In the OR filter fields, I typed (HORNY AND MAC),(HORNY AND MASTURBATION). The parentheses essentially tied the search terms together, just like parentheses in math. So now the memory search would still pull specific memories where Leah felt love for only me. Since the NOT filters still apply to all other tags, my new filters would add additional memories to the list where Leah felt horny for me and memories where she felt horny and masturbated (but not fantasizing about any of the people I put in the NOT section). Boolean operators were the core of my programming knowledge, so the complex filtering felt nearly intuitive.

I glanced through the new memories filtered into the file explorer. Out of 50 files, there were only two where the properties showed she was horny for me. I expected I’d get the best results if I adjusted those two to be at the top of the list. In the properties menu, I manually edited the weight of the tags associated with her feeling horny and attracted to me in those files by a factor of 10. This shot them up to the top of the list. I also painstakingly added my name to the tags on every single one of the gifs where she was masturbating alone. I deleted any other people's names that I missed with the NOT list. Lastly, I manually reduced the weight of all tags pertaining to the emotions of guilt, shame, and anxiety. The need for a find-and-replace tool was immediately evident. After several minutes of that, I figured it was time to give her a spin before I got too late. With a click, the command was executed, and I lifted her VR helmet.

Even before awareness returned to her eyes, her hands found their places at her tits and pussy precisely as I saw on the .gif files. Her breathing increased, and I’m sure her pussy started getting wet too.

When her eyes refocused, the love was still there, but it was overshadowed by the “come to bed” eyes she made at me.

“Oh, Mac, I need you,” she moaned while quickly pulling down her panties and sliding off her dress straps. Her ample braless tits heaved with her deep breaths. Her nipples were covered with beige pasties. I watched intently as she ripped them off, revealing her pink perky nipples.

I ran my fingers along her cute slit, and a smile replaced my formerly calculating countenance. Leah reacted to my touch by moaning and arching her back for me. This time I could feel the heat pouring off of her visibly wet pussy. Her hand replaced mine the instant I moved away.

“Did that feel good, Leah?” I asked in a deep voice.

“Yes, babe, so good!” She moaned. “I’ve always imagined you touching me! I love it, I love you!”

I felt the heat of my arousal wash over me after hearing her words. My heart pounded, my knees went weak, and my hands shook. I had fantasized about this moment for many years. In a rush, I stripped off my clothes. As my cock sprung free, Leah’s eyes went wide in awe.

“It’s bigger than I imagined!” She exclaimed. “I-I can’t believe that’s going to fit inside me!”

Now, don’t get me wrong I enjoyed the compliment, but I could tell she was serious. I’m slightly above average at best. I would be surprised if one of her previous boyfriends weren’t larger or equal to my size.

“Leah, are you a virgin?” I asked. I knew she wasn’t, but I wondered if she knew.

“Mmm, you haven’t fucked me yet,” she said between moans. “Though I’ve spent a lot of time… mmm imagining it.”

“Oh, I’ve imagined it a lot too, Leah,” I growled, “but that’s not exactly what I asked. Has anyone else ever had sex with you?”

“Who else is there?” She asked in confusion.

That answered my question. My careful deletion of everyone else’s names from her memories also had the wonderful side effect of making her unable to acknowledge that anyone but me existed.

With that knowledge secured, I stopped questioning and lay beside her. Her left hand frantically circled her clit, while her right gently massaged her tits. Taking her left hand in mine, I guided her to caress my cock. To my surprise, she knew what to do; it was clear jacking me… or originally someone else… was one of her fantasies in the filtered memories. I moaned as I felt Leah’s touch for the first time. I returned the favor and slipped two fingers into her wet, willing opening.

I smirked as she squealed in pleasure. In her filtered mind, this was the first time she’d felt another’s touch. Moreover, I was the only guy she’d ever fantasized about or thought about. The power and control I had over my old best friend was intoxicating.

Everything I did elicited a moan or pleasurable squirming from Leah. I could do no wrong. Hell, she was incapable of considering anything outside of the rose-colored glasses of HORNY and LOVE tags. I groped her tits, I pinched her nipples, I fucked her with as many fingers as I could fit. When her mouth opened for a particularly sexy moan, I slipped my fingers into her mouth. I was surprised that she didn’t suck them or anything, though. I guess she never fantasized about blowjobs in the memories I had filtered. “I’ll fix this next time,” I whispered into her ear. ”For now, tell me you love me and want me.”

“Mac, I love you completely,” she chirped, “Please take me; I want only you; I want you to be my first.”

Without a second thought, I kissed her passionately. This time, we danced to the same tune. The more sexually charged my kiss got, the more she squirmed and moaned into my mouth. With my thoughts clouded completely by lust for this mind-controlled beauty, I slipped my hard cock straight into her wet unprotected pussy. She screamed her pleasure easily loud enough for all my neighbors to know. I didn’t care. Leah was finally all mine like she was always meant to be.

I hadn’t gotten a good look at Leah’s ass yet, so I pulled out and flipped her onto her hands and knees. She obediently lifted her ass and laid her head down on my pillow to give me a good view as I slipped back into her tight cunt. With an invincible feeling of power, I slapped her ass and pulled her hair while I fucked her hard and fast. I had never had sex this raw and this rough before. The sight of her round ass covered in red handprints will be forever etched into my mind.

I could feel she was getting close to cumming for me. My rhythm stabilized, and I focused on getting myself close too. In just a few more seconds, Leah arched her back and moaned loudly as her pussy clenched around my cock. The extra pressure pushed me over the edge. With a flash of clarity, I pulled out just in time and came spurt after spurt all over her ass.

We both collapsed onto the bed beside each other to catch our breath. I had expected to feel guilt and shame for my actions. Don’t get me wrong, I did, but my desire to improve her filters and maybe make this permanent was far more potent.

I grabbed my shirt to clean my cum off of her ass. It was a shame I couldn’t cum inside her, but that would have been tough to explain after I removed the filters. She rolled back onto her back after I cleaned her off.

With a huge grin, she said, “That was amazing! Nothing I imagined came even close. I want you to fuck me all the time! I’m still ready for more even now.”

She slipped her hand back down to her pussy as if to make her point clear.

“I agree, Leah,” I said. “I’ve dreamed of this for a long time.”

I enjoyed the sounds of her moans building again as she continued fingering herself. I assumed that nothing would make her be able to stop being horny or masturbating at this point. Almost all of her memories were of playing with her pussy, or wanting to play with it after all.

Before she got me hard again, I took one final look at her beautiful naked body and then quickly put the VR helmet back onto her head.

I ran to get a damp washcloth and cleaned her up a little more before replacing her pasties, underwear, and dress back how they were. With a sigh, I turned back to my computer and began sadly working on reverting her to normal. I noticed that the AI sent me two new .gif files. They were memories from the time during testing after the headset was removed.

For a moment, I felt some fear that maybe Hana remembered, but then I recalled all she did was sleep and stay entirely mindless. Looking at the properties of the new files from Leah’s brain, I noticed they only contained positive emotions and tags, with the majority of the weight applied to LOVE, HORNY, and MAC. I highly doubted that it would be a problem to leave these in Leah’s memories. With the sheer weight of the tags, it was hard to imagine that she would question the new memory.

I decided to leave the memories intact but modified the notes section on both of them to clearly highlight that she came on to me and decided she loved me and wanted me on her own accord. I wanted her to know without a doubt that I consensually fulfilled her desires. I also ensured any text mentioning the VR headset was deleted from the half-gibberish sections of the notes.

Begrudgingly, I removed all the tags after saving a preset with the current settings. I did not, however, undo my edits to the tags and weights within the 50 or so memories I had modified. The effects of leaving those changes seemed to be a risk-free way to keep her thinking of me on more romantic terms and maybe even increase her libido a bit.

With the tags removed, I was pleased to see the memory of us having sex was now her most defining memory. Due to the significant weight I added to the LOVE and HORNY tags, there were also a couple of memories of her masturbating to thoughts of me that crept their way into the top 25. I couldn’t wait to see how this would change her personality.

Lastly, before removing the headset, I sorted by recent memories and deleted the memory of me explaining my new software and asking her to test it. The memory gap could be an issue, but I had a hunch the brain would be pretty resilient. Humans are quite good at ignoring or explaining gaps in memories.

After returning the sorting to default, I took a deep breath and pulled off the headset. As usual, she didn’t respond immediately. I placed the headset away but within reach, just in case.

Finally, her eyes focused, and she looked at me with a demure smile. “Wow! T-that was… that was really good.” She spoke softly, with her cheeks shining red in embarrassment. “I don’t know what came over me… I mean, other than you.”

I smiled and laughed as she giggled shyly at her joke. “Good one! I guess we just both really needed it. It just felt right.”

“I think so too. I-I’ve never had sex that rough before, but I loved it sooooo much.” She exclaimed without meeting my eyes. “A-and I know I said some things… a-and I’m just not sure. Can we take this slow?”

I could tell she recalled her memory of telling me she loved me. With all her other memories added back in, I’m sure she felt a bit confused. “Yeah, I get it. This was very sudden, and we spoke out of passion,” I replied. “I’m good with taking a step back and taking things slow. But I do not regret what we did tonight one bit, and I hope you don’t either. No matter what happens, you’ll always be my best friend too.”

Leah smiled and nodded her head as I spoke. “I don’t regret it either!” She exclaimed happily. “And I’ll always be your friend, too. I think I’m going to head to bed and think about this more tomorrow. Oh, and thanks for redressing me after I passed out. That was sweet of you.”

She then gave me a peck on the cheek and headed to her room. I let out a huge sigh of relief. It seemed like everything worked out. All the program functions seemed to work, and I didn’t notice a hint of suspicion in her demeanor. A bit of confusion and embarrassment, yes, but that was to be expected.

With a thud, I shut the screen of my laptop and put everything away. I was exhausted. Any further work on the program would wait until tomorrow.

After a quick warm shower, I quietly sneaked just outside of Leah’s door. Pressing my ear to the cold wooden surface, I could clearly make out her cute moans. I could also ever so slightly hear her whisper, “I love you, Mac; please don’t stop.”

I whispered back, “Oh, I don’t intend to, Leah.” Then, I quietly shuffled back to my room and crawled into bed.
