This chapter is longer than usual because I always like to include copious amounts of sex in my chapters, and there was a fair bit of exposition in this one. I hope you like it! I'm building up for the next few chapters of some really sexy, interesting stuff! Follow me if you want to access to the next chapters early.

[Part 1][Part 2][Part 3][Part 4][Part 5- This one!]

It’s been two months since I came clean to you, bearing the entire details of what I had done. My greatest transgression on the table, my guilt bared raw.

Since acquiring those drugs that fateful evening in Prague I have experienced everything I have ever desired. I’ve used your body in countless ways at my pleasure through your pussy, mouth and even your tightest of holes. And the whole time you’ve begged me for it, you’ve begged me to stuff you full, to thrust inside of you at an ever increasing pace. You’ve been insatiable, and ultimately, when I introduced the white powder: desperate and denied.

As you now know, my guilt got the better of me; with every thrust in your sopping wet pussy, the squelch of your juices against my cock, I would feel this pang in my chest, a reminder that I made you this way. That I made you this perfect fucktoy. It wasn’t something you requested, or even knew about, but a pharmacological phenomenon I put upon your desperate, willing body.

I knew deep down you wanted it, that you craved to be like this, but my greater conscious couldn’t abide by how depraved you had become. You were more than animalistic; inserting any object I left unattended into one of your sloppy holes, fucking your own throat raw until tears ran down your face, and using your ass until I had to take away your toys out safety.

So one day I just stopped. I stopped giving you the pink powder, and let you come down. At first you just slept, and slept, for days, but within a few days you awoke and groggily confronted me about the happenings of the last month.

I came clean. I showed you this journal, my recordings of the events since I got the powder from Max, and you were stunned, but your reaction was not what I was expecting. I thought there would be anger, tears, I thought you would hit me and scratch and claw and become enraged at my mere presence, but instead, you just sat quietly with the journal in your hand, silently contemplating.

I begged you to say something, anything. I was fully in panic mode. I knew I was going to jail, and for a long time. I had given you an untested substance without your knowledge, and I had brutalized and abused your body with wanton disregard to your desires.When you eventually did speak, it was quiet. At first, I wasn’t sure if I had even heard you correctly. “I…. kind of liked it.” you whispered in a mousey voice.

Then, with a drawn out pause: “But I’m pretty pissed at you. You did this all without my consent. You could have asked me if I wanted to try it at least! Maybe I would have said yes?”

“What?” my eyes bulged. I stared at your petite frame. “What do you mean you liked it? I put you through hell. I took advantage of your body with these drugs. I turned you into a sex crazed doll!”

“I mean, I’m definitely furious at you.” you said, closing my journal with some force. “And I am glad to be back to normal. I mean my friends are probably worried sick about me, let alone my parents! Nobody has heard from me in a month! You really should have just asked. We could have had some fun with this stuff…” You sighed and leaned back into your chair.I was still panicking on the inside, convinced I was going to jail for a long, long time.

“I… uh,” I stuttered “didn’t think you would have agreed to it. You really would have?”

“Of course! I mean just for a little bit, like a day. What girl doesn’t want to have incredible orgasms over and over?”

“And what about when I added in the drug that made it so you couldn’t come?” I cringed at repeating what I had done to you.

“Well, that part was really hard, but I did enjoy the extra desperation I had from being so unfulfilled. But ultimately it was way too long, and super fucked up that you didn’t ask me, so yes, I still am mad.

You’re obviously going to have to pay for this.” you continued. “But no, I won’t report you.” a sly smile curled on your lips. “You’ll just need to do some things for me…”

That month I did everything you asked of me. Entire days spent cleaning the house until it was spotless, and then cleaning it some more. I would eat you out for hours on end. I took care of everything in your life, I helped host for friends that were worried about you, I showered you with gifts, I tried to be the perfect boyfriend. All so that I could make up for this horrible, illegal thing I had done.

All the while you promised not to report me, but you wielded my transgression like a leash, pulling me this way and that, effectively, turning the tables in a way. I was ok with it, even I felt used.

I had had my fun and gotten away with it.This was my penitence.

The worst was when you’d make comments about how I was the “desperate one”, how I “wished I could fuck you” like you were withholding your holes from me in some ironic punishment. Since you rarely let me fuck you, I masturbated almost exclusively to my deep collection of memories.

Porn did nothing for me anymore, it was all too vanilla and fake. I thought of my dick slamming into the back of your throat, of you locked in up your cage begging for me to use you, or of fucking your ass as fast as possible with with all manner of thick, veiny dildos.

However no matter how hard I tried, you seemed to get more withdrawn. Your mood grew more frustrated and depressed. Your friends started to get worried again, you stopped responding to texts or hanging out at their events. You seemed tired, lethargic, and melancholy. I would try to cheer you up by cooking dinner or buying you little gifts, I even tried to schedule date nights. I’d go down on you as much as possible, as if my mouth could somehow make up for the terribleness I wrought. But no matter what I tried you’d get irritated or sad, it was like nothing gave you pleasure anymore.

Then one day.

“I kind of… want to go back” you whispered to me one night while we were watching a show.

“I hate that I do, I mean I’m a fucking good girl. Like let’s be honest, I’m perfect” You did always have a bit of an ego

“But I’ve never felt so good.”“What?” I was taken aback. “You mean on the drugs?”

“Yes, silly, on the drugs.” You poked my chest in a condescending way, which irritated me. How was I supposed to know? A few weeks ago I thought I was going to jail for giving you the drugs, now you wanted them back?

“I could have stopped, you know. I knew what you were giving me, on some level, was causing my feelings. But fuck, it felt so, so good. I fucking miss it.” you sighed.

“Wait, are you serious?” I replied, incredulous. “You really liked me drugging you, fucking you senseless, and putting you in a cage and in denial for my own use?”

“I mean what I said” you shot back indignantly. “I fucking liked it. So stop being such a white knight and listen to what I’m saying.”

You were still the same you, even if you were asking to be made into something different.

“I don’t know why I have to spell it out for you. So are you going to take me to meet this Max, or do I have to fly out there myself?”

Not three days later and we were on a plane to Prague by way of Frankfurt. You made me buy you a business class ticket, my last act of repentance. To be honest, you were still being kind of a bitch, every time the flight attendants would leave you’d tease my cock outside of my pants, whispering in my ear that you’d never give me the release I craved sober. I was rock hard and the guilt of the drugging having long since worn off (due to my copious efforts at atonement) I felt irritated by your teasing and withholding again. I considered trying to fuck one of the flight attendants so I didn’t have to tolerate your teasing anymore. But I knew what was coming - I could wait a little longer put you in your place and turn you into the slut you so clearly wanted to be on the inside.

In Prague you wanted to go shopping and buy a bunch of expensive, glittery dresses. I guess this was another act of independence, perhaps internally you were fighting with your decision to pursue the drugs effects, and you wanted to exert your autonomy. It didn’t matter, I was content to spend the money knowing that soon you wouldn’t cost much more than some light daily nourishment, probably even less than a family dog.

On the night we were to meet max you wore the prettiest of the dresses, a shiny, embroidered sequin gown that ended around mid-thigh, showing off your perfectly shaped legs. You let me watch you change without so much as even an offer for me to go down on you.

“I’m such a good girl” you giggled to yourself, adjusting the straps and putting your hair up in an elaborate braid. Giving your body a whirl you blew a kiss at me and then sauntered out of the hotel and into the lobby.

“Fine,” I said to myself. “Well see how she is in a few hours.”

We followed the same path to get to Max’s secret laboratory as the first time, down the long cement corridor into the dimly lit room. I had warned him beforehand you were coming, but that you were interested in testing some of the product and that you wouldn’t be trouble.

Inside the lab Max and his assistant Philippe were busy mixing together different formulations with a binding agent. He ran over to the door as we came in and shook your hand, exclaiming how happy he was to meet a “satisfied” customer. They had the same girl I remembered from last time, Klara, with them, ostensibly to test out new product formulas.

“Come check out this new formula.” Max gestured rapidly to me. “It’s pretty cool, all one needs to do is spread a small amount” he held up a small dollop of a tan cream “of this onto the skin and it has the same effect as the pink powder we gave you a while back. Check it out. Klara, dear.”

Klara, who was looking decidedly more worn out these days, with dark bags under her eyes, walked over to Max and held out her arm docilely. Max spread the dollop of the cream onto her arm and told her to hold her arm out and steady as long as possible. Philippe, in the corner, clicked a stopwatch and the beep resonated throughout the room. You lounged against one of the medical tables, high end dress and makeup looking out of place in contrast to the stark interior.

After only a few minutes Klara’s arm began to waver and her pupils dilated. “Hold it out, Klara!” Max commanded. Klara tried her best, but her hand started to shiver, and eventually, instinctively moved towards her clit and started rubbing. Soon she was circling furiously as she moaned out loud in front of the group of us.

I knew at this point how the powder works, but I was amazed at how quickly Klara went from a normal, if disheveled woman, to rubbing her clit. And then only moments later, grinding her ass against Philippe, begging to be fucked. “Good girl, Klara” Max cooed. “3minutes, 45 seconds. A new record. I think this new absorption modulator is really working.

“By the way, did we mention? We’ve been testing something new on Klara here”

I shook my head.

“Well, we’ve been using that white powder we gave you as a sample, but we isolated the denial compound and were able to map it via simple conditioning to specific acts. So now we have Klara in a constant state of denial at all times, she has no ability to orgasm unless we preform very specific acts on her. This keeps her docile and ready at all times. For instance,” he gestured to Phillipe who had whipped out his cock and started pounding Klara against one of the research tables, her brown hair swishing back and forth in the violent rhythm. “She has no ability to orgasm from this pounding, no matter how effectively Phillipe wrecks her hole. But if he was to switch to anal, or deep-throating, she has the ability to cum within minutes.”

Phillipe upon hearing this dutifully pulled out from Klara’s slit and jammed his veiny cock into Klara’s ass. Of course no lubrication was necessary, the drug made Klara so wet that the juices dripped off of his cock and it easily slid into her tight hole. Within a minute Klaras moans increased to an incredibly intense desperate, whine, at a pitch I had never before heard a woman make before. It was a sound from deep within her body and soul, high pitched and brutal.

Out of the corner of my eye I could see you starting to step back and forth uncomfortably. A nervous glance around and you shifted your dress just slightly; I wondered if you were feeling a little aroused. I looked at Max to see if he noticed, and he flashing a smile and a knowing wink.

A little confused, I look back and realized you had pulled up your sequined dress and were fully rubbing your exposed clit now watching as the round and bald Philippe (somebody you’d never have even dreamed of finding attractive, a man, who, if sober, you’d likely have ignored in a pitying way) pounded Klara’s asshole into oblivion, her slender frame convulsing in ecstasy as she came, her pussy gaping and convulsing around air, desperate to be filled.

Watching this scene unfold it hit me - the handshake! He must have had the cream on his hand when he greeted you. Obviously I didn’t know how the drug worked well enough… since Max had it on his hands yet hadn’t gotten affected, maybe it only affects women? I shook myself from my wandering thoughts as the depraved scene unfolded.

Klara was continuing to convulse and writhe, so Phillipe put a strong hand on her neck and pushed her head down against the table to hold her still.

“Whoo she’s bucking huh!? Let me know if you want me to tie her up!” Max whooped in enjoyment. “And there goes our special guest finally!”

You rushed over and in a fit of desperation were trying to position your now exposed crotch in front of Philippe’s thrusting cock, hoping to catch a stray thrust. Phillipe, to his credit, was ignoring you completely. Max put his hand on my shoulder.

“He can fuck her if you’d like to watch” he said matter of factly. She’s just a hole now, as you know. “Or, if you’d like to use her again, you can take advantage. We won’t judge.” he smirked at me, and I wasn’t sure whether he somehow knew of the involuntary denial I had been subjected to over the past month.

“In fact, if you’d like to use Klara, she’s free too. Philippe won’t mind, it’s basically a job for him at this point.” He laughed, a full, bellied laugh, a little unnerving if I’m being honest. He almost liked this too much.

At least I had some shame. Not enough to stop me from joining in, of course, but more than some people.

“Philippe, let our guest here do what he wants with these sluts. I need his data from his experiment, anyway.” he gestured to the squat, hairy man who stopped fucking Klara and pulled out his cock, disproportionately large on his small stature.

I had been waiting for this invitation all night. I wasted no time in joining you and Klara by the table and I pushed inside of you, spreading your tight folds with my throbbing cock. A treat I had been denied far too long. You let out a long, airy moan, seemingly relaxing into a place you had missed since coming off the powder, that place of floaty, unburdened desire. “Thank you, Daddy” you sighed, to no-one in particular, lost in the depths of your mind’s arousal.

As I thrust in, I made a promise to myself. I’d never let you stop from taking what was mine ever again.
