Super potent drug helps me use up my gf

With things weird at home(read previous parts) I decided to blow off some steam, and got my hands on a wonder drug.

Soon after that fucked confrontation with mom everything felt heavy at home. New month coming, rent due, bills stacking. Sisters Ana, Aish, and Ameya weren’t kicking in much, just their college shit and part time pocket money. Me and mom were the main ones carrying it, but we weren’t even talking proper. She avoided me like I was poison, eyes down at dinner, quick to leave any room I entered. Sisters noticed the cold vibe but I brushed it off.
I got back to hustling hard. Odd jobs, deals, finding shit for people. That’s when my gf Sim came into the picture more. We’ve been together a couple years. She’s short, thick, pale smooth skin, big tits and fat ass. Met her when she bought some stuff from me back then—weed, pills, whatever. Turned into us fucking soon after.
Things were very frustrating at home, so I definitely needed to blow off some steam. We had guests visiting at house, so privacy was at a premium. Not that I am complaining, because my normal, sexy, little sister, my aunt Elizabeth and her two petite sexy daughters, my cousins Mia and nish were visiting. They were both a little bit younger than me, mia being 18 and nish being 19. Both were not as thick as my sisters or mom, all three in fact were tall, and petite, but hella sexy.
Anyways I texted my girlfriend, "let's hang out. Our usual spot" on headache to a local club, a place I was very well aware of and we knew everybody around. Soon I press her down at the corner table and order myself a drink, my sexy girlfriend walked in. She is short, thick and pale and hela nasty.

We sat down, flirted and drank nice drinks.

"So, what's got you in a bad mood?" She asked me
"Well my moms being a pain, after the whole wedding thing, her sister and daughters are here, not to mention i need money to pay the bills and shit."
"OH yeah? Your cousins also came? " she asked, her voice insinuating
"Yeah, and they're staying for a couple weeks I think"
"They're staying, and you invited me? When your cousins are in town, you spend all day ogglin9g them."
"Well its not my fault theyre hotter than you" I joked, but she didnt enjoy it very much haha.

She pouted, but we both laughed and continued our conversations. We were both very horny by this point so we knew what was bout to happen. Drinks flowed. We slipped out to a dark alley nearby. People walking past could see if they looked. I pushed her against the wall, yanked her top down so her big pale tits spilled out. “On your knees. Let's see if you're better than my cousins.” She dropped, pulled my cock out and sucked hungry, gagging loud while cars passed. I facefucked her rough, spit dripping, then bent her over and pounded her tight pussy raw. She moaned loud People definitely watched, but we didn't care, or should i say i didn't, i also didn't care if she was worried. I came deep inside her then we fixed up laughing, and left the bar. The night ended soon after, and I got back home.
I was super annoyed still because I still had to deal with guests, and also sharing a room with my cousin Mia.
The next day, I got a text from a friend. Not the good kinda friend, the kinda friend that called me to give me shit. He asked me to meet at a local park, public place, but quiet.
He told me about some new product in the market. Now I don't really do drugs. I sometimes source them for people and make a quick buck, but not super stuck into that sort of stuff. But I was Intrigued, because he didn't call me often, only for very certain stuff.
When I got there, he told me about some new shit floating in the market. He knew I didn't take any drugs myself, but I did occasionally get some other types of stuff. He told me he had a nice pill for men, increasing stamina and shit. Sounded intriguing and I wasn't one to shy away from some fun. But it was the second item, that was going to be much more important i ever realized.
Basically he had this new liquid, made with some sort of surgical anesthetic or something, and basically this small vial of glass, filled with a colorless smellless, and tasteless liquid was a drug used for sleep aid and some other things.
We bought you exactly what this truck could be used for but I also did not know how potent and how strong this drug was, not to mention, it really wasn't very safe to just use it without testing it first. I talked the pill and a few vials off the drug at a discounted price. He wanted me to test, or whatever and see what could be done with it. And if it worked how I thought it can, shit was about to get serious.
Now I could test it on anyone in the world, but it was risky. What if the person wakes up, or what if they remember or feel what was happening or happened. So it was quite risky. And only one person in my life I could take the risk with. My sexy fuckmeat of a gf. But I couldn't tell her about it, cuz then I wont get the real response.
I went to her place, and after dinner put the liquid in a drink, and waited. Not to be overly weird but this was an experiment. I felt like a scientist in a lab testing it on a human specimen. I needed to know its limits. On paper he told me it was so potent that for 6 to 8 hours, the person was down, out and all their senses were shut. But I didn't know how much of let's say action I could get away with. And thats what I needed to test.

Now I waited an hour after the supposed "sleep" began. I shook her around to start, but no response. But I still didn't believe it would actually work as strong as he said. This drug sounded like a fake drug in the movies.
I got a little bit rougher on her. Heavier shoves, slaps, pinches etc. Just to see the limit. Seeing her like that, so peaceful and clueless, I began touching her. I slapped her around, groped her pale white tits, slapped her face, punched her tummy.
Soon, I was undressing her. She didn't move. No reaction. A few really tight slaps that would break normal sleeps, her cheeks red and bruising and she still didn't show a reaction.
I knew I could push it, and how couldn't I. As her naked unconscious body laid under me, I went straight for her throat. A throat with no resistance feels like heaven. And so it did. Slobbering throat, no resistance and no reaction from her side.
Then soon I was using her ass. If she didn't wake from that, I could be sure of this drug works as advertised. Atleast in the moment. And her ass also showed no resistance. It was almost like she couldn't feel nothing, in that sleep. And it was so fun. A living, breathing sex doll, with no brattiness of a real whore whining in my ear about what I can and can't do.

A couple hours of fucking every hole, I knew the stamina pill worked pretty well too. And I was close to finish up. I came all over her, and left her as is. And went to sleep.

The next morning my girlfriend woke me up whining. Asking me what happened. "Did we have sex yesterday, why dont I remember anything?" She asked me.
I told her what was going on, and what I did. The violated look she gave me was priceless, but she knew who was in charge. Plus she was pretty intrigued by this drug too. I showed her some videos I took at night, and my fucked up gf looked at it with some serious intrigue.

With 3 more vials in my possession, I knew I could use these up well, but more importantly I needed more of them. And if they always worked like this, then we might be in for a crazy ride.
