The journey to Paul's Aunt and Uncle's place had been slightly tense. His parents had been chastising him for not having his life together since before they had left home.

Paul had finished college a few months before, but was undecided of his next steps. His Mother, Kate, had again asked him what he was doing about getting a job and, as usual this had led to some heated discussion.

"...and then you could afford to get your own place, or at least start contributing like your sister does." his Dad, John, added to underline the points already made.

Paul was fuming with anger, not helped when her looked across from his side of the car's back seat to see his 22 year old sister, Jenny, sneering at him. She had always been the golden child and seemed to get forgiven so easily for all of her indiscretions. There had never been any discussions about Jenny having to move out. Paul strongly suspected that this was because his Dad liked having the house filled with her hot friends.

Hopefully this would all be dispelled once they arrived. It was the first time in a while that the two sides of Paul's family had got together. He was looking forward to seeing his cousin, Tom, although apprehensive as they usually managed to get into trouble.

Tom and Paul had grown up together and were now both 19. He sometimes felt that they had allowed themselves to reveal rather too much to one another. From swapping porn to discussing girls they knew to admitting to fantasies involving members of their friendship circle and even family.

Paul followed his family into the house where they were warmly welcomed by his Dad's brother, Phil and his wife, Julia.

Julia was, as ever, effusive about seeing them, hugging them each in turn. She was a fairly short lady which only acted to accentuate her curves. Paul couldn't help but notice that her outfit was maybe just a little more revealing than usual, with slightly more cleavage and leg on show. It wasn't that out of the ordinary and Paul just enjoyed the view.

His Mum did drop a comment about liking Julia's new top, something that she responded to by sticking her chest out a little to show it off more. This movement made her nipples stand out a little through the fabric as she thanked Kate. Paul observed his Dad's gaze drawn to the prominent bumps.

Paul always got a mix of pleasure and discomfort when Aunt Julia pressed her large tits against him for a hug. As she squeezed him tightly, she made small talk with everyone about how wonderful it was to see them and that the twins, Tom's older brothers, would be joining them a little later.

She added that unfortunately, May, their oldest, had been drafted in for an extra shift at work last minute. This elicited a sigh from Jenny, who had been looking forward to spending some time with her cousin and regular partner in crime. Paul and his Dad also felt a sense of disappointment, although they were more subtle about it. May had a tendency to push the boundaries of what was acceptable to wear even further than Jenny did.

As soon as Aunt Julia released him, Tom was grabbed by his cousin who had appeared from upstairs. As he was pulled urgently away from the rest of the family, he heard his Mum make some comment about the boys clearly having some important catching up to do and his Aunt start offering them all drinks.

"We'll be back in a minute, Mum" shouted Tom as he dragged Paul upstairs to his bedroom and closed the door behind them. Tom was a little taller than Paul, skinny with a messy mop of light brown hair that almost covered his eyes.

He was excited, out of breath and spoke quickly and quietly to Paul, drawing his attention to a cardboard box he had just pulled out from under his bed. The box rattled as he lifted it onto the bed and Paul could see it contained a number of small plastic bottles.

"I found these in my Dad's office last week" Tom whispered to Paul, who was examining the bottles. Each was labelled with a letter and clearly contained some sort of pill.

"I guessed the dirty old fucker had bought some boner pills online or something," he chuckled. This seemed a believable suggestion to Paul. Both lads were very aware of Phil's darker, dirtier side, having checked through his browser history and 'hidden' hard drive together quite regularly. They'd also listened in on him and Julia having sex a few times, giggling and mimicking the sounds, but also ending up secretly quite aroused by the action.

Tom continued, "But then I found this..." He produced a small piece of paper and pushed it into Paul's hand. Paul read it through, thinking that it must have been some kind of joke.

"WARNING USE WITH CAUTION: PERSONALITY PILLS. Each pill will modify the behaviour of the subject for about 6 hours. Subsequently, subject will fall into a deep sleep awaking refreshed and unaware of what happened under the influence of the pills. Some residual effects may be observed. See menu below for details. A higher dose will have a stronger effect. Combinations of pills may produce unpredictable results. Pills are instantly soluble and tasteless. Non-toxic, but results may vary and we accept no responsibility for outcomes." Paul laughed out loud as he finished, only to be shushed by his cousin. Their eyes met and he could see that Tom wasn't joking.

"So, you're telling me your Dad has bought a box of 'magic sex pills'? What a mug! You don't think he's tried them do you?"

"Look in the box," Tom encouraged him.

Paul quickly noticed that the seal on the bottle labelled 'C' had been broken. Checking the menu on the paper, he read aloud "C: Slutty lady. Female only. Lowered inhibition, heightened libido. Subject will desire sex constantly and do all they can to get what they want." Paul again laughed.

"He must've tried these out while you and I were on that trip last month." Tom whispered excitedly. "I thought there was something odd about his behaviour before I left and after I returned. And surely you must've noticed Mum flashing the goods even more than usual?"

Paul thought back to their greeting and had to agree that although his Aunt was not averse to a well-fitting, revealing outfit, it wouldn't usually be for this kind of do.

"It's subsided a bit over the last couple of weeks," Tom continued, "but to start with she was very... um... hands-on and kept wandering around the place wearing very little and flirting outrageously with anyone she met. I thought she was having some kind of mid-life crisis and then I found these. I've been dying to show you."

Paul remained sceptical but could see that his cousin was deadly serious. "So have you checked where he might have got them?" he asked.

Tom replied "I've searched and searched online and found nothing listed anywhere. I'm wondering if they might have been something he got from work?" Uncle Phil worked for a big pharmaceutical company and the exact nature of his work was something he frequently told them he couldn't discuss. He usually dispelled their questions with some little joke about saving the world or having to kill them if they found out too much.

"Do you want to try them out?" Tom blurted out excitedly.

Paul was more reserved, actually a little nervous. "How and when are we gonna find ourselves in a situation where that was even possible?" he asked, realising as he spoke that his cousin meant they try them out right now.

"You've got to be fucking mad" Paul shouted, to a series of 'shushs' from Tom.

"I only meant the... um... less aggressive ones so we can see if they're for real" Tom responded.

"We can't, this is our fucking family! What if it all goes wrong?" Paul was trying to remain the voice of reason here. However he couldn't help but find himself curious and actually very aroused by the idea of fucking his family up. It would be a hot way to get revenge for the way they've treated him recently. "We can't." he said in such a weak, non-committed way that Tom realised he might be able to win this one over.

"Look, I know you'd just love seeing them all act a bit weird and uncomfortable, especially that bitch sister of yours." Tom laughed.

Paul couldn't deny his sister was such a pain. She was used to getting her way and used her looks as a means to achieve it. She regarded her brother with total contempt. As for his parents, well they deserved to be brought down a peg or two. So, much as he did love them all really, he couldn't deny that he liked the idea of messing with their heads for a few hours. He still had reservations about doing it alongside Tom, who had a tendency to push things too far.

"Look", Tom pleaded, "Pill F would be a great fun one for our Mums."

Looking down the list, Paul read "F: Party Girl. Female only. Fills subject with the desire for fun and makes them the life and soul of the party. Excitement, dancing and drinking become their main drives." He knew his Mum had been a big-time party girl in her youth, he'd been told stories of all night raves and clubbing and it was something he could hardly equate with his calm, professional mother. He had to admit it would be entertaining to see that side of her unlocked.

"And pill M for our dads" Tom continued. What Paul read reminded him of his first thought when he saw the box. "M: Big man. Male only. Gives subject peak sexual prowess. An almost unstoppable erection and ability to ejaculate repeatedly. Accompanied with a gentle desire for sex. May cause swelling."

"Sounds like it could be a little dangerous?" Paul questioned.

Tom was quick to respond, he'd clearly given this a lot of thought. "Oh come on, it'll just make them uncomfortably hard and make it more difficult for them to hide those cheeky looks they both grab of any women they see. They deserve it."

Paul had to admit that was a funny idea. They'd repeatedly laughed about both their pervy Dads trying to get sideways looks at any hot women they saw, including their Sisters and Mums. Paul realised It would be an entertaining thing to watch unfold, his own cock tingling slightly at the thought of it.

"And I had something special in mind for little-miss-perfect Jenny. You know how she wraps our Dads around her finger? I thought pill V would be fun for her." Paul turned the paper over to find V in the back. "V:" he read, "Family fun. Subject will become sexually aroused around family members and fantasise about a whole range of inappropriate family games".

"Fuck no!" Paul interjected, it just sounded wrong to do that, despite his sister being a massive pain in the ass.

"But, think about it" Tom responded, with another prepared answer, "it only makes her think about these things, it'll give her some much needed conflict and take away from that over-confidence and power she wields. Plus remember how mercilessly she's scolded us for checking her out in her slutty outfits, it would be great payback."

Paul's uncertainty persisted, despite Tom's reassurances and watertight arguments. He thought again about how his cousin tended not to know when to stop. Plus he didn't dare ask how he thought his Dad wouldn't notice that the other bottles were open afterwards.

"Lets face it, they probably don't actually do anything anyway..." Tom went on, "and at most, we'll get a good laugh. Plus I'm doing it, even if you aren't in, so you're gonna be along for the ride. My house, my rules!"

Shit, thought Paul, how dare he invoke that agreement that they'd used since they were kids. It was only supposed to be for deciding what computer game to play or what movie to watch. Paul sighed deeply, "I know you're gonna do it anyway, so lets get it over and done with!" Secretly he was already throbbing at the idea of fooling about with the family.

Tom grinned broadly, he knew all about his cousins perverted mind control fantasies, something they'd discussed at length in the past, so he knew Paul wouldn't need much persuasion. "Go downstairs and just check where everyone is." Tom instructed Paul, "I'll sneak the box down into the utility room so we can easily access the pills as we need them."

This made Paul realise that Tom had no intention of stopping with the plan he'd already stated, but he was now resigned to going along with him and trying to do his usual job of bringing a voice of reason to Tom's schemes.

Paul sneaked quietly downstairs. The kitchen was now clear and the family had moved into the lounge area. His sister was lolled in an arm chair browsing her phone, his Mum on a separate armchair and his Dad and Uncle Phil sharing the large sofa. Aunt Julia was stood in the middle of them all gabbling on about some family gossip.

He took a moment to regard his Aunt following what he'd learned from his brother. She wore a figure hugging skirt that just grazed below her large round arse and her top squeezed her large tits together forming a decent amount of cleavage in the plunging neckline. Clearly aware of the attention this was getting from the two men in the room, she shifted from foot to foot, making her tits sway and jiggle.

Was this the after-effect of some weird new drug, or was this just how Jenny was feeling today? She looked great to Paul and seemed so self-assured.

Paul also noted that each family member had a half-finished drink and that this could be their perfect opportunity. He signalled to Tom who quickly, but carefully dashed across the kitchen into the side utility room with the box of pills. Before Paul could sneak back out of the room to join Tom, Aunt Julia spotted him. She smiled and used her arms to push her tits forward a little before saying "Oh, hi love, are you boys coming back? Is Tom there?"

"Um.... Yes, Aunt Julia, he's.... um... just in the toilet, he'll be here soon." Paul replied.

"Do help yourself to the juice and could you bring the jugs through and top us all up please." she requested, scanning him up and down as she spoke, the vaguest hint of a lascivious look passing across her face.

"Yeah, sure." Paul replied, heading to the table and looking for his cousin.

Tom emerged from the side room with five pills in his hand. He passed two red ones to Paul saying, "You sort out our Mums. I'll deal with the others". He showed him the two blue pills, clearly for their Dads and a kind-of purple, sparkling pill for his sister.

"So what have you boys been up to?" Paul's Mum asked as they entered the room.

"Oh, you know, just checking out a new game I got." lied Tom with absolute confidence.

"Probably perving at something, knowing you two." Jenny sneered as they started to pass around the room, the rest of the family chuckling at this comment. This further convinced Paul that they all deserved the pills that were coming their way.

Paul headed over to his Mum and was easily able to slip one of the red pills into her glass unnoticed as he topped it up. It vanished on contact with the liquid. She thanked him, lifted the glass and took a large sip.

As she did this, Paul went to his Aunt's glass, which he thought would be difficult to drug without getting caught. But with his Mum drinking, his sister fixated on her phone and his Dad and Uncle focused on Aunt Julia's tits, it was actually really easy.

His aunt also thanked him, leaning over as he poured the drink, giving him a full view down her top. She picked up the glass, downed the whole thing, then bounced on the spot in a playful celebration, making her tits bounce for the everyone watching her. He saw his Mum roll her eyes slightly, but she maintained a smile, taking another big drink from her glass.

As Paul turned to return the jug to the kitchen, he realised Tom was already ahead of him, just leaving the room. "I hope he didn't bottle it", Paul thought to himself, but he could see Tom's gigantic, mirthful grin, so he knew the plan was going ahead.

Back in the kitchen, Paul grabbed Tom and quietly asked "How long do you think they will take to work?"

"No idea." Paul replied, "But I think it's time we got ourselves in a prime viewing position."

They headed into the lounge again, with their own drinks and pulled up two chairs from the dining table, behind Julia. From there the whole family were visible, as were Julia's sizeable butt cheeks, quivering in the tight confines of her skirt.

Over the next few minutes, each of them finished their drinks off and Tom was again sent to get the jug for a refill.

Twenty minutes of so passed and Julia continued chatting away, mainly to Kate, about nothing in particular. The boys' Dads began their own discussion and Jenny continued to be absorbed by her phone.

Jenny looked up at one point and checked out the two men siting opposite her. Her Dad was looking particularly hansom today. His dark hair had slight flecks of grey in it, but he was in excellent shape for a man in his mid-40s, still kept fit. Uncle Phil was also kind-of hot in his way, she thought, chubbier and with slightly thinning hair, but he had the same masculine jawline as his brother and dressed well.

A little thrill shot through her as her gaze moved over them and she was reminded of a few inappropriate fantasies she'd had in the past. None of these seemed quite as shameful as she'd thought at the time. She smiled lazily across and was delighted when the both men noticed her and returned the smile.

That was the moment that John felt the first gentle spasm through his dick as it started to rise to attention. He shifted in his seat slightly so that his growing erection was out of sight and tried to ignore it. He was always unsettled by his daughter's ability to do that kind of thing, and felt embarrassed that this was by no means the first time this had happened.

Across from him, his brother was managing the same situation. The number of times he'd jerked off to fantasies about Jenny was quite disgraceful. Maybe he should have taken his wife's offer of some more sex this morning instead of heading off to complete some work before the family arrived. But he'd still felt exhausted from fulfilling her post-pills level of need. This drain on his reserves had now completely melted away and he was feeling somewhat invigorated, particularly in his pants.

All of this had completely passed the expectant lads by. They tried to amuse themselves, chatting quietly and giggling, all the while scanning the room for changes. A further five minutes passed before Paul noticed his Mum increasingly reacting to the gentle background music that was playing on the stereo.

Initially her feet were tapping along to the beat but soon she was starting to jig her whole body. This was mirrored by Julia who continued talking at her Sister-in-law, but was now bouncing rhythmically on the spot. Eventually, Kate blurted out to Julia. "We need to get more of a party vibe going on in here!" and laughed.

Julia just let out a whoop of agreement pushing her arms into the air. Looking down at herself, Kate was somewhat disappointed in the jeans and floral blouse she had on. "I don't feel party-ready in this though!" she stated. Julia grabbed her, clearly agreeing, saying "we could always borrow some of May's going-out outfits, I'm sure she won't mind" and started to drag her sister-in-law towards the stairs up to her daughter's bedroom.

"Care to join?" Kate asked, looking across to Jenny who was watching the two older women closely.

"Its OK Mum, you two knock yourselves out." She laughed, unable to comprehend what had gotten into them. However, she couldn't help but look forward to seeing their milfy bodies crammed into some of May's outfits. Her Mum had a reasonably athletic figure, topped off with a sizable pair of tits that she always cursed when she was working out. The idea of seeing that on show was further amplifying the tingle Jenny was having difficulty ignoring.

Her eyes followed the two ladies as Kate was dragged across the room. "Hold on." Her mum interjected before they left, "I need a proper drink to get me in the mood." She picked up a large, almost untapped, bottle of vodka from the drinks cabinet by the door and then followed Julia up the stairs, both whooping, giggling and chanting "Party! Party!"
