When my sister Abby inadvertently drank some of my test compound, it led to a whole range of soul searching questions on morality, and possible guilt trips. In the end we had talked it through and came to the only possible conclusion to keep Abby safe and unharmed.
I knew the compound would make her voraciously sexual, she simply wouldn't be able to control herself and would fall easy prey to any sexual predators. The idea of her having sex with any casual acquaintance because of my experimental drug, or being used and abused by multiple partners was too much to bear, both for her and for me. We came to the mutual decision to keep the whole weekend under wraps, or as we thought of it, 'in house.'
Yes, I knew it meant a reluctant incestuous relationship for the duration of the weekend, but with any luck the effects of the drug should be wearing off by late Sunday night, or early Monday morning. In the meantime, Abby was susceptible to and easily influenced by the slightest sexual thoughts or words, all of which she'd amply displayed since Friday night when she first took my, 'love potion.'
I'd even gone out early on Saturday morning, when she was sleeping between bouts of love making, to an Anne Summers sex shop, and bought her a vibrator. I knew I wouldn't be able to keep up with her demands, and the sex toy would help to keep her more urgent needs at bay while I was recovering in between having sex with her.
Perhaps I'm making it sound as if I'm just making excuses to justify having sex with my sister. As if it was some sort of onerous task to alleviate any stigma on my part of being a sister fucker, and I was just some poor hard done by brother. Nothing could be further from the truth. It was the only practical solution to the major, and very urgent problem facing us, but we couldn't deny that it became an amazingly beautiful and pleasurable experience for us both.
Our love for each other had always been strong, but now we'd been thrown together by circumstances in a way that neither of us had ever envisaged. Yes, it was awkward for us both to start with, but there was no other solution and we eventually embraced it, reluctantly to start with, then more enthusiastically as the undoubted pleasure and love led to a wholehearted commitment.
Our Saturday afternoon was spent in love making, and trying to find ways to satisfy Abby's sexual hunger. I briefly thought of calling in help in the shape of Eleanor Hepburn, my first test subject who had done the same as Abby, drank the compound unwittingly and spent an entire weekend voraciously sexual. I knew she'd be delighted to help, but something held me back. The need for absolute secrecy was imperative, always at the forefront of my mind, and I was reluctant to involve anyone else, even Eleanor, my most trusted sexual partner and confidante.
By late Saturday afternoon Abby and I we were both fucked to a frazzle. Completely exhausted, but boy, was it good. A nap seemed a good option, so we both retired to our own bedrooms to remove any temptation that sleeping together was sure to bring. I set the alarm clock for 6pm. That would give us time to get up, get showered so we weren't reeking of sex, and get out to the hotel where I had booked a table for two. I thought an evening out, may take her mind off sex even if just for a little while, plus it would be a good idea to give us both a break, get us out of the house for a change of scenery, and god knows we needed it.
Well, as the poet once said, 'the best laid plans of mice and men, etc.' It all went wrong when Abby sneaked into the shower behind me just as I was working up a lather. She ensured we worked up a different kind of lather, by running her soap filled hand along the length of my cock, and from there things went rapidly downhill. I ended up fucking her in the shower giving her a real classic, 'knee trembler,' against the wall of the shower while the warm water rained down on us both. She came quickly, then crouched in front of me to suck me to a mind blowing orgasm.
'Fuckin hell Abby,' I said in mock protest, 'we were supposed to be saving it for later, when we came home from being out.' She laughed, and slapped my wet bare arse as I turned the water off, and stepped out of the shower.
'Fuck that,' she laughed again. 'I saw your bare arse and your cock, and I couldn't help myself. I was determined not to touch you, and I fully intended to leave you to shower in peace, but somehow my pussy let me down, and I wanted you. Sorry, I just couldn't fight it, no matter how I tried.'
'Abby, it was lovely, you're lovely,' I told her. 'It will wear off soon enough, and then you'll be blaming me for taking advantage of you in your distress.' She shook her head violently, as she used a large bath towel to dry herself and me.
'That will never happen,' she declared earnestly. 'Okay, your, "fuck juice," has made me incredibly horny, so horny that it controls my mind in some ways, and I'm... no, we're doing things I never thought we'd do, but I'm having a wonderful weekend with someone I love. No regrets, I promise you, none whatsoever. How about you?' she finished. I shook my head.
'No regrets for me either,' I assured her. 'I was reluctant to take advantage of your "condition," but it became obvious that it was the only solution. Not only are you stunningly beautiful in every way, but you're a marvellous lover too. I've never made love to anyone who could compare to you in bed.' Then I wickedly added, 'or in the shower, or the kitchen, the living room, both bedrooms.' She laughed and playfully slapped my arm.
'Okay, okay, enough,' she said laughing. 'When I want it, I want it... I need it, and you know that well enough. What's wrong old fella?' she teased in a condescending voice, 'can't you keep up with your much younger sister?' I pointed to the bed and said just one word.
'Doggy,' she stopped laughing, and came into my arms, kissing me lovingly, and then quickly breaking away took up our preferred position on the edge of the bed. Arse up, head down resting on her forearms, bringing her already wet pussy into the premium position for fucking.
I stepped up behind her, lined my cock up with her stunning cunt, fingering it for a few seconds to check if it was ready for me. I needn't have worried, she'd been perpetually wet all weekend and was still wet, so I threaded my cock between those generous pouty lips of hers and on into the glorious wet, warmth that I'd become more familiar with than I should ever have been, or had any right to be.
'Oh fuck yes,' she gasped, 'nobody fucks me as good as you... oh holy fuck, use me... make me come... again... I want... it.'
'Yeah, yeah, I know you want it,' I said in a mock disrespectful tone. 'You're a hot arsed, cock loving slut that needs fucked none-stop to keep her happy.' My seemingly harsh words sank into her brain spurring her on even more.
'Oh fuck yes...' she agreed, 'I'm your slut... your sister slut... oh fuck... oh my gawd yesss... fuck me... fuck me... harder please... oh fuck... fuck... your dirty slutty sister... fuck meeee,' and my wonderfully dirty slutty sister came again, loud and proud.
It was just too soon for me come again, right after she'd sucked my balls dry in the shower just a short time earlier. So, I was happy to withdraw, still hard, and leave it as unfinished business. I knew I'd be dipping my cock into her wet pussy sooner or later, and given her voracious appetite, I figure it would be sooner. I just hoped she'd be able to manage the excursion to the hotel and hold out all the way through the meal without needing more. Somehow, I doubted it, but we'd cross that bridge when we came to it.
With Abby's unbridled lust temporarily satisfied we managed to get dressed and out of the house without further incident. Talking about, 'dressed,' when Abby came out of her bedroom looking like a million dollars, I just looked at her, almost speechless.
'Well, she asked, 'do I scrub up okay, what do you think?' She was wearing the proverbial, 'little black dress,' which hugged her stunning figure. Not too short, just above the knee, sleeveless, with a high neck line. It looked very demure, but it had class, and so did Abby. She had put her hair up in a very formal style, her only jewellery being a double strand pearl necklace, a gold watch on her left wrist, a gold bracelet on her right which matched the dangling gold earrings. The whole outfit was completed by the black patent leather shoes. High stiletto heels, not too high, about two inches, because she was tall anyway, and they made her legs look absolutely to die for.
'Oh my god Abby, you look so hot. I can hardly believe that this is my little sister. You wouldn't look out of place in any company in the world. You're simply stunning.' I didn't run out of superlatives, I could have gone on and on, but Abby called a halt.
'Enough,' she commanded, 'you'll be making me feel horny again, cease and desist, and let's go... now!' she added emphatically, and we left the house, into the car and off to the hotel.
The hotel was very busy with it being a Saturday night, plus it was the main wedding venue in the city. It had three function rooms and tonight they all seemed to be in use, the reception area was busy and we had to thread our way through the crowd of guests just standing about, drinks in hand talking to each other. I noticed Abby was getting loads of attention when we made our entrance, and I enjoyed seeing the envious looks I was getting. I was so proud of my little sister, and of course nobody knew she was my sister, which made it all the better.
The restaurant was busy, but quieter than the foyer we had just walked through, and we were quickly shown to our table. A table I had carefully chosen to give us a little privacy if it was called for. I'd been to this restaurant a few times before and knew the layout of the tables and booths, and the one I had requested was slightly off to one side with not a lot of passing traffic, and by that I mean there were no people heading past our table to reach the toilets, or the exit, and no staff passing by to reach the kitchens. Once we were seated we were pretty much on our own. I had a sneaking suspicion that Abby wouldn't make it through the night without being relieved in some way.
'This is nice,' she said looking round the room. 'Thank you for bringing me,' and she reached over and kissed my cheek, all very prim and proper. I smiled.
'On the contrary, thank you for being my partner for the evening. It does my ego a world of good to be seen with the most beautiful, not to mention the classiest looking woman in the room.' She laughed, then said something that got my immediate attention.
