A family plays a game from a truck stop

"Are we there yet?"

"No, we need more gas. We won't be there for a few more hours."

As the old van pulled into a pumping station, Alex turned to his wife, Maria. "Could you get me some chips? I'm gonna fill us up."

"I want a candy bar," their youngest child, Joey, called from the back row.

"Yeah, well I want to go back to college," their oldest, Rosa, said, not looking up from her phone.

Rosa was 20, and had been protesting the trip the whole time. She'd gone off to college in another state two years ago, and had to be dragged back home by her mother for this trip.

Every summer, they had taken this drive up to a cabin in the woods for a week. It used to be something everyone looked forward to, and a great bonding opportunity.

Maria sighed. Where did it all go wrong?

As she went inside to get the snacks, her eyes were drawn to a shelf near the wall with a bright blue box on it.

"Alternate Lives- a great game for growing closer to each other! 50% off."

Well, why not? The game would've been cheap no matter what, but the current sale price was a steal. And it sounded like just the thing to kick the week off. Picking up the chips and chocolate for everyone else, Maria went back to the car, where Alex had just finished filling up.

Once they had both gotten back in their seats, Alex wordlessly took the chips from Maria, and she passed the chocolate back to Joey. She had also bought a second bar for their middle child, John.

Looking again at the plain blue box, she wondered why she had bought it for a second, before a ripple passed through her.

She was so glad she had bought that game! It was going to be so fun to play, and she knew that everyone would enjoy the week a lot more.

Back at the truck stop, the clerk looked over at the shelf where she had put it, only to see that it was missing. As she remembered the woman she sold the box to, she swore under her breath. Despite what she tried, the game always found it's way into someone else's possession, and then back into hers.

As she stepped out to remove the sign she didn't remember putting there, her cock and balls swayed as she walked, dripping slightly on the floor.

A few hours later, the van pulled into the dirt driveway in front of the old cabin.

"Okay, everyone out," Alex said. "John, Rosa; help me get the trunks. Joey, get your backpack and put it in your room."

Despite Rosa's groans, she went to grab the trunks of food and clothes they had brought for the week, grabbing one end as John got the other.

After everything from the van had been moved into the cabin, Maria pulled out the game again.

"Everyone, could you come to the living room?"

As people slowly arrived, Joey first and Rosa last, Maria opened the box and took out the rulesheet.

"What's this about, Mom?" Rosa said, dispassionately.

"I know you're… not thrilled about this vacation, so I got this game! The advertisement said it was a 'great game for growing closer to each other', and… well, I feel like we need that! It's going to be a fun way to kick off the week."

"Well, have fun," Rosa said, turning away. "I'm going to bed."

"You sit down right now, young lady! We are going to play this game, we are going to enjoy it, and we are going to have a fun family vacation!"

"Jeez, okay," Rosa said, sitting down. "Whatever I have to do to get you to let me go to my room."

"How does this game work, Mom?"

"Let me see…"

"'“Pretend with your friends and acquaintances with this wacky game that you are completely new people, living whole other lives of and amazing variety! Explore these other worlds together as you grow closer to one another than you could have ever otherwise!”

All changes are unaware, unless otherwise stated by a card.

Each player has 3 cards in their hand, on their turn they pick a player and use a card on them, rolling if necessary for certain effects as directed by the specific card. draw on your turn to get back to 3 if necessary.

Game ends when one player manages to have 10 effects on them. The deck is already shuffled.' Sounds simple enough." While the term 'unaware' sounded off, the box's magic made sure nobody questioned things.

"So, I'll go first," Maria said, taking three cards; Mental:Command, Wild:Physical Choice, and Special: Hyper Hottie. Having no clue what Hyper Hottie meant, she focused on the first two. Reading through their effects, Command immediately stuck out. While it was just a game, and these cards couldn't actually change people, she still played it in front of Rosa. "Rosa, you really enjoy being here, and love your family."

Once she finished talking, the magic took hold, rewriting reality to fit Maria's command. Of course, being the kind of game it was, it obeyed the letter of the command, if not the spirit.

Ever since she had hit puberty, Rosa had been cursed with incestuous feelings for her whole family. That was part of why she had left for college; ashamed of these feelings, she had tried to get away from her family. But now that she was back among them, she was deeply aroused, and loving it. Drawing three cards, she looked over them.

Wild: Normal, Mental: Wardrobe Malfunction, and another Normal.Taking a closer look at the text of Normal, she realized just what she could use it for. Despite nobody realizing what Maria's card had done, or that she had even played it, Rosa subconsciously believed the cards would do as they said. 'Whatever the target is currently doing is completely normal'. However, as nobody was currently engaged in any sort of sexy activity for her to normalize, she decided to save the two cards for later. For now, she used her other card.

"You dress sluttier and show a lot of skin," she said, playing 'Wardrobe Malfunction' in front of Maria.

"Rosa! Why wou-" before Maria's indignation could fully register, her clothes shifted. A long-sleeved shirt and jeans shifted into a crop top and booty-shorts, as Maria began to show a lot of skin indeed. All of her clothes in the trunks changed too, into thongs and bikinis and similar slutty ensembles.

Alex was next to draw three cards: he wasn't too into this game either, but he figured that, since Maria was so invested in it, he might as well play along. Drawing "Hyper Hottie", "Redistribution", and "Add Another," he wasn't really sure what to do with them. All three of them needed him to choose a 'body part', for some reason, but he was deeply lacking in ideas. Luckily, 'Hyper Hottie' had the option of letting him roll a dice to decide instead. He wasn't sure about the name, but whatever. Turning to his youngest son, Joey, he lay down the card. "Okay, now I roll… are there any dice?"

"In the box, Dad," John said.

"Thanks, sport." Rolling the dice, he saw a 2 on the top face. "Okay, so now…"

Since the 2 corresponded to Joey's butt, it began to grow to a ridiculous size. As his pants strained, then tore, his ass reached the size of a beanbag chair, and he shifted onto the floor.

It was both impressive and unusual that Joey's pants had held out as long as they had. Hell, it was unusual he even managed to fit some pants on at all.

For as long as the whole family has remembered, Joey's rear had been incredibly large- enough that he rarely sat in chairs, or wore anything more than his specially-elastic underwear, the only thing he could stretch over his amazing ass. It wasn't anything unusual, just how he was.

"Your turn, John… I think," Joey said, resting on his rump.

"Got it." John drew his hand- 'Command', 'Discard', and 'Wild: Multiplier'. Unsure what to do with anything, he played 'Discard', shuffling his entire hand back into the deck. Drawing 'Dommy Mommy', 'Furry Fun', and another 'Multiplier', he just gave up and decided to play 'Furry Fun' on his father, rolling for the effect.

The 2, representing 'Feline Form', quickly took effect- a pair of black cat ears burst from his graying hair, and a long, similarly black tail, from his pants. Unbeknownst to them all (save for Maria, who now remembered it), his penis also changed to a feline one, with barbs near the tip that made it hard to pull out.

His children, or at least John and Rosa, also changed a little, with John inheriting the tail and Rosa the ears.

"Whose turn is it meow?" Alex asked, the card also affecting his manner of speech.

"My turn, Dad," Joey said.

As he looked at his hand of 'Hyper Hottie', 'Breasts', and 'Free-Use Friend', he wasn't sure what to do. Having no real exposure to porn or the 'mature' side of the internet, despite his massive ass, and having forgotten when his dad played 'Hyper Hottie' on him, he just chose one at random. "Uhhh… John," he chose, remembering that John hadn't had any effects yet, despite not remembering what any of the effects were.

In a moment, the world shifted. Before the shift, everyone was sitting in chairs in a circle (except Joey, who was on the floor). Now, however, John had moved over to where Rosa was sitting, and was in the process of fucking her.

This, like everything else, was normal. John was available to fuck and be fucked by anyone who needed it. He felt no attraction to his sister, but she needed it, and the cosmos basically required it of him. It was just how it was.

Rosa, meanwhile, was questioning why she ever moved away when she could get her brother to fuck her whenever she wanted. All she knew was that she'd be making good use of him for the rest of the week.

"Should we have dinner meow? We can continue when we get back."

"Good idea. Rosa, come help set up the table."

"But Mom, John's fucking me right now!" Rosa protested.

"You can pick up right where you left off once we start dinner."
