The Slut Pill

My girlfriend Rachel came in from work later than me, as usual. While my job was pretty normal, boring, 9-5 routine, she had a really cool job as a scientist. Something to do with biology, it always went over my head, but she did some pretty cool experiments. She was wearing her lab coat, which I always found sexy. She really was stunning, even with her minimal work make up- beautiful, soft, feminine features, long blonde hair, petite with thick curves. She had a funny smile on her face today.

"We've got a new project, fertility drugs" she told me

"Oh yeah?"

"They're desperate to get those useless pandas to shag. You won't believe how many money they've spent. Anyway, there seems to have been a breakthrough. It's amazing, actually. The pair we have are suddenly going at it like crazy"

I laughed at the idea

"I'm serious. Anyway, the drug seems really safe..." she pulled two tiny bottles out her pocket.

"Are you allowed to take those?"

"Not strictly. But I couldn't resist."

There was a bit of an awkward silence. I think I knew what she was getting at. We'd been living together a year, and our sex life was getting pretty routine. We still did it most nights, but it felt like we were out of surprises, going through the motions.

"I just thought we could have a little try. It's two drugs- one we give to the female, making her submissive. The other we give to the male, sends him the other way".

"And it would work on humans?"

"I reckon so. It couldn't do any damage. Lets try it, join me in the bedroom in ten".

It was a bit of a strange idea, but I couldn't see much wrong with it. Might be just the thing we need. I waited downstairs, getting impatient. I loved the idea of Rachel lying on her back, desperate for me to fuck her. Finally, it was ten minutes, I went into our bedroom.

I had my first pleasant surprise, Rachel was wearing the sexiest outfit I'd ever seen her in. It was a black corset, with black matching panties. Her sexy curves looked incredible in it, huge round tits pressed tight against her body, her hips spreading wide, her round arse on display at the back.

"Did you take your stuff yet?" I asked. She smiled

"No, I thought we should do it together. It only takes a few seconds to kick in". She handed me one of the little bottles.

"Just take the tiniest sip" she advised, holding the other bottle to her mouth. We sipped together, and smiled nervously. We kissed, waiting for it to kick in. I felt a rush, it felt good, like the rise on one of the ectasy tablets I used to take occasionally. I reached down and grabbed her arse, and she... gripped me by the neck, pushing me onto the bed. I instinctively cowered. What was going on? One look at the wicked grin on her face made me realise.

"You didn't give me-" she slapped my face

"Did I tell you which bottle was which?"

"No, but-" she slapped me again. A little part of me wanted to shout at her, be furious... but a big part of me liked it.

"Take your fucking clothes off, fast"

I scrambled to obey, accidently chocking myself in my rush to remove my tie. As I lifted my legs to pull my trousers off, she smacked my arse hard

"Too slow!" she said, and kept spanking my arse as I undressed. I moaned with each hit. I lay, still, naked and submissive. She looked at me with an intensity I'd never seen before. I was scared, but hard as a rock.

"You can wear these" she said, slowly pulling down her black panties, then pulling them up my legs. "Now you're my little slave whore. What are you?" she asked, putting her hand back round my neck.

"Your little slave whore, mistress" I replied. Her smile grew wider at that. She knelt on my shoulders, and lowered her pussy onto my face.

"Then lick me, whore".

I immediately obeyed, concentrating hard on pleasuring mistress. She started grinding her pussy into my face, and growling with satisfacation as I licked carefully around her clit. She reached back, and grabbed my nipples tight between her finger nails. I sighed and licked harder. Rachel's cunt tasted incredible, I felt like I was on the verge of cumming myself, I couldn't believe how much I could enjoy giving head, enjoying every little surge of pain as mistress twisted my nipples.

Suddenly, when I thought she was done, she pushed herself up and pissed right in my face. It barely even fazed me, as if it was the obvious thing to do next. I opened my mouth wide and took the golden shower full on. Mistress clearly approved- she slammed her cunt back onto my face, and no sooner I put my tongue back onto her clit than she started to cum hard, moaning as she rubbed herself right into my face, covering my mouth and nose, suffocating me. I offered no resistance as I became more and more breathless, wondering calmly if she would let me up before I passed out. Entirely her choice.

Mistress let me breath just as my senses were starting to fade. She rolled off my and sat on the bed, breathing heavily, sighing with contentment. I felt alarmed, realising this might be over. I lifted and spread my legs.

"Mistress, please fuck me". Rachel looked down at me.

"You want me to pleasure you? You'll have to plead better than that. Like a real dirty little slave whore" I didn't miss a beat

"Please, my wonderful mistress, I'm nothing but a filthy little whore, I need to be fucked, I beg you, fuck my dirty whole".

Mistress slid two fingers into her wet cunt, then started rubbing the outside of my hole.

"Please mistress, please, I need to be fucked-"

"Shut up now, whore" mistress snapped, and clamped her other hand firmly around my mouth. I'd never had anything in my arse before, but there was nothing else I wanted at this moment.

Finally, a single, smooth finger slid up me. I moaned hard with the release of having my mistress enter me. Then two fingers went up me, stretching my virgin hole. Mistress started pumping her fingers in my harder, and I took it like a true slut. In my pleasure, I'd almost forgotten about my little dick, but Rachel hadn't. She gave it a few tugs, and I came up my body, onto my face. She slowly pulled out my arse as I licked up the cum on my face.

Mistress held me tight as I relaxed into her big, beautiful breasts. We cuddled for a while, and the drugs started to wear off. It was like a switch in my brain, suddenly I was back to normal, and I could hardly believe what had just happened. I pulled Rachel into a regular hug.

"Baby?" I asked

"Yeah?"

"Can we do that again?"

"Definitely". There was still a hint of that look I'd seen in her eye "But I'm getting some toys in for next time.
