Bonding over Games and Boobs

You sit there for a few moments, stunned at what just happened. You managed to time travel, break reality, and survived its reconstruction all in the span of a few moments. Was this what always happened when you wrote a Rule and you just don't remember it? No, because the book made a note of it. So this had to be new. Apparently, you have to be more careful about this stuff since it inked in that rule as to prevent further tampering with your birth. Alright, you had 4 twins sisters anyways so what the fuck did you need to muck about with it anyways?

You check your clock, 2 and a half hours till the curse due to the alterations. A million little ideas, course corrections, and others come pouring in your mind as your heart beats faster and faster. You hadn't really thought this one through. Sure, they would love you based on the Rules that you set in place but they would be strangers to you.

You look at your now expansive room, suspiciously clean outside of a new vanity covered with many different products. Four new beds line the same wall as your own. One is neatly made with a comforter with a flower motif. The others are slightly rumpled, looking barely presentable in their messiness. You guess that like your sisters (god that was odd for you to think about) resented having to make their beds and did the bare minimum to keep your parents off of your collective backs. One of the beds, it's comforter a solid color rather than anything special, had an open laptop on it. You walked over to investigate, finding it locked down but still powered. You guess that she (whoever she is) is still home and just went out to get something. Much to your surprise and approval, this was no ordinary laptop but a Xenosoft. Reaching through your (nerdy) memories you figure that this Xenosoft is only a model years off of the cutting edge, which makes it good enough to play modern titles really smoothly.

You could almost imagine it, a girl as nerdy as you scrimping and saving for this all summer. As you investigated further, you could see another user screen with your name on it. Maybe you worked together to get it? Now the image is just more vivid. Now it is you mowing the lawns, while your sister washes the cars. You would meet together after the work was done and discuss the time tables you two would set, what titles you wanted to play, how the memory allotment should go. A phantom taste of cherries goes through your senses as you imagine splurging on them despite yourselves. The time that you stuck your tongue out at Am-

Woah!

What the hell was that!?! Those weren't your memories! You never knew someone like that! That was someone else's life nostalgically flashing before your eyes! What the hell was that about?!?

You began to go through an existential crisis-

"Viiiince~ Quit drooling over our baby! It's still my turn you know~!"

When suddenly a girl's voice cut through your panic, both foreign and yet familiar adding to your confusion.

She was tall for a girl, about 5 feet and 8 inches. You were tall too, about 5'11'' boarding on 6' nothing, so with minor stooping you could meet her eye to eye. Her skin was clear but very pale, clearly not the outdoorsy type. Her hair was a dark brown but short, not even reaching her neck, but it was styled in a simple yet becoming way ("Wigs are easier to cosplay with, Vince" You hear in your mind). Her eyes were a light hazle and kind, if a little miffed. Her breasts were nice, either a lower end C-cup or an upper tiered B. She had long legs and a nice figure, not an hourglass but not at all ugly, and something told you her ass was even better. She was dressed in shorts and a tank-top, but you could see her bare shoulders not marred by those modern ****-traps called bras telling you that she was dressing comfy more than anything.

You wondered who this stranger was. What this cute girl was talking about when she was talking about 'our baby'. In that moment, all of your cultivated nerd-lore left you, your mind only working on trying to identify her. What was her name, you wondered.

'Amber', parts unknown supplied.

You push down the panic at suddenly knowing Amber's name, and put on your best innocent look. "Oh, I know it's still your turn Amber. But you can't stop a guy from drooling over a hot babe like Etna over here." Where did that name come from?

Amber's face scrunched up, playfully disgusted.

"No Vincent. We are not naming her Etna. I don't care how much we played the fuck out of Disgaea, no baby of mine is going to be called that! Felicity~ has such a better ring to it anyway." She crossed her arms and leaned down, playfully flirting and giving a good view of her cleavage. How you could tell that it was only playful when the only girl you knew that well was the President of the Manga club, you don't know.

"I don't know... " Despite your growing arousal, you managed to fire back. In motions that somehow felt familiar, you stretched backward showing off your newly toned abs. ".. Smoke is overrated anyway, don't ya think? There are better OTPs out there."

You two hold those positions for a second, staring each other down.

Then as if the bubble had popped, you both laughed. You walked up and wrapped an arm around her shoulders.

"Yeah yeah yeah, I think you win this round. There you go, Etna's all yours Amber. Try not to give her viruses from porn sites, kay?"

You feel a pillow strike your head.

"Shut uppp! That never happened! Girls don't watch porn, no matter what you think." Her tone was unconvincing.

You walked out of the room with a wave... Then proceeded to lock yourself in the connected bathroom.

What the fuck was that!?! The way you talked to Amber, it was like you knew her! You weren't even that flirty with Pres and she was a proven pervert!

You sit on the toilet, pondering Amber. As you think about her, more and more of these... memories keep popping up. Now that she mentioned it, you do remember playing Disgaea with someone else, taking turns. Yet, you also remember playing it alone after school. Yet you remember being annoyed at having to take turns, since Amber was so much better than you and it would take forever for her to die or finish a battle. Then R***** would barge in and-

Okay, now that you were outside Amber's cute girl passive effect, you could think straight. You left the Rulebook at your(?) desk in y(our) room, so you would have to figure this out without experimentation.

Okay, it was clear that the Rule that gave you Sisters worked really well. Problem is, now you are remembering it like that was always the case. Every other time you use the Rulebook, you could remember the difference. This was important, so if you wanted to change the Rule back all you would have to do was.. erase... oh. OH!

It seems that if you wrote a Rule in ink it would give you memories to match the new world, since if you wrote it in ink you wouldn't be able to change it in the first place. However, it seems as if you still got to keep your original memories too. That... made things easier for you, since now you could remember your shared past with the rest of your family. You didn't remember everything yet, like who the hell your other three sisters were and what they looked like, so you clearly needed a 'reminder' in order to recall everything. Meaning, of course, that you need to do some good ol' fashioned sibling bonding with your sisters before the nudism 'curse' you placed on your family kicks in. You know, so that you can know them a little better before you get to know their bodies.

A fair price for being born, you think.

You're not 100% sure that they will agree though.

You look around the bathroom, no outside your confused state you notice just how much of everything there is. You're not on the toilet, but one of three. There are a whopping 5 sinks! You can tell which one is 'yours' due to the... minimal makeup? Oh, what the hell. Now you remember your sisters dressing you in drag and teaching you the ways of makeup. So now you know more about skin tones, contours, and brands than any man normally does. You surprisingly don't mind. Apparently being surrounded by girls in this timeline makes being a manly man less of a priority to you, though you're not about to be going out in a dress anytime soon. In fact, now another memory bombards you, this one of Amber lamenting the lost chance to have all five of you looking like cute anime girls for a con since you started gaining masculine muscle tone and features.

Alright, you need to get off this track before you remember anything embarrassing.

You walk out to see Amber lying on her bed on her front, her boobs pressed on the bed and her feet swinging in the air, her ass as nice and tight as your instincts told you... crying?

For a second, a protective streak that you never knew was there took over... till you heard the background music.

Ah, she just watched episode two of Boku no Hero, all is right in the world....

A smirk forms on you as you creep up to your sister, your bare feet barely making a sound. You get up right behind her annnd....

"Stop crying! For I am here!"

Start the tickling.

It starts at her sides, and you slowly start making your way up.

"Ah aha, Vince, aha, oh come on, ha, you're ruining the AHAH! moment."

Knowledge of her weak points floods your mind, and your hands crawl up to her armpits.

At this point, she's flipped over and you change your attack. She clamped her arms shut, so you attack her ribs! Her laughter is a soft thing, more along the lines of a bell than anything human.

It was all fun and games... till you starting tickling her boobs somehow. Your hands were lightly motioning over her generous chest. Neither of you noticed... till she let out a moan. Both of you froze.

You looked into her eyes, and she into yours...

Then you two laughed again. Apparently, this had happened before and Amber never really seemed to mind.

"See, this is why I never let you tickle me. You're like a god-damn harem rom-com lead Vince! If I didn't know any better, I would think you were doing this on purpose!"

There is something in her eyes that you don't quite recognize... hope, maybe. Or was it worry? There is a temptation to stay, to see how far things could go... but you wanted to meet your other sisters too and you had a feeling that if you started this... it would take a while, if it worked at all.
