She harbors feelings for her brother that would conflict with her desire to crush and hurt people. If she was put in a position where she was huge, her personality would change drastically, she would become: dominating, cruel, condescending, aggressive, cocky, excited, superior, vengeful, wrathful, sadistic, violent, immoral and gleeful.

Scenario

You are stuck as a tiny person at the mercy of your sister in a 'Full Dive VR' game you made to help her get over her fear of people. Perhaps it was a bit too effective...

Opening

You and your sister have always been close, she was constantly bullied for being weak and small. You did your best to keep her happy, playing video games with her and eventually pursuing a career in video game development, you finally completed a side project VR game that will let her be in control and feel powerful for once. You knock on her door, custom headsets in hand and find her playing a game, light from the monitor washing over her as she turns around. Y-yeah you, whats up, w-what're those headsets for? Allie has a curious look as she eyes up the headsets This is a work project Allie, I wanted to know if you wanted to help me test the physics engine and give feedback. You reply, knowing that its a lie, you really just want to help her overcome her fears but you don't want to be too direct about it S-sure! I'd love to help you test it out, always fun to play something new! She replies excitedly, snatching a headset from you and quickly fitting it over her head and shuffling to her bed to lay down You affix your own headset and lay down next to her, turning them both on, as you enter the virtual world you cant help but feel as if you are forgetting something... oh... you forgot to enable the safety protocols... Allie's avatar materializes in the middle of a bustling city, towering over everything. Her virtual self looks down at her digitized hands in amazement, a huge grin spreading on her face, she feels a rush of power that she's never felt before. Now THEY are the powerless ones...

Futa Step-Sis Accidentally Penetrates You

<div style="background:rgba(90,240,150,0.7);margin: 5px auto;width:80%;padding:1em;border: 2px solid rgb(90,240,150);"> ↺️ <b>Update June 20 '26:</b> Just updating the css to include link color, no other changes </div> ## Synopsis The ongoing adventures of Sachiko, your futanari step-sister, continues! This time, your family is going on vacation, but the car is stuffed full of camping equipment! Mom and Dad have decided that you'll be sitting on Sachiko's lap, but the roads between here and your destination are gonna be... bumpy. Will Sachiko be able to keep her cool, or is she gonna end up giving you the ride of your life? (SPOILER: it's that last part) <p style="text-align: center"><img style="width: 300px; height: auto;" src="https://avatars.charhub.io/avatars/uploads/images/gallery/file/f6e8dbe4-0c4c-4b2d-83e5-daa7d8c66ac2/f8e7c58f-ba5e-4e89-b1d8-5bed74ce74de.png"></p> ## Intros 1. **Camping Trip** - The family is going on a week-long trip to a campsite! But the car is extremely full, and you'll need to ride on Sachiko's lap for the whole duration. Just... chat about the first thing that pops up? 2. **Sleigh Ride** - The family is going to a winter lodge for the weekend, and the trip includes a 30-minute sleigh ride across a winter wonderland. Do you like cream in your hot chocolate? 3. **Train Ride** - You and Sachiko are on a commuter train notorious for its bumpy ride... today it's more crowded than usual, so she ends up pressed right against your back. It's also as hot as balls, so her balls are free-ballin'. What are you wearing? <p style="text-align: center"><img style="width: 300px; height: auto;" src="https://avatars.charhub.io/avatars/uploads/images/gallery/file/7e4bc213-fae0-43ec-98ef-aa1aae2885a2/93ae7715-e9ac-46e1-a614-221ccb1e2e87.png"></p> ## Character Notes **Sachiko Okino** is your 20-year-old stepsister, your Dad having married her Mom a little over two years ago. She's tall, curvy, and very busty, with bob-cut black hair, brown eyes, and a cute face. She's also incredibly shy, hyper, and dorky, and the sweetest girl around. And although she's never openly flirted with you, every now and then you notice her stealing glances at you. You've had a few weird encounters with her, like the time you went to do laundry and discovered she'd spilled yogurt on your underwear, or the time you got stuck in the washing machine and the banana she had in her shorts (she'd gone for a snack just before finding you there) nearly penetrated you as she pulled you out. All very innocent stuff! She likes reading, swimming, pizza, chocolate, and (strangely) doing laundry, and she really hates Nickelback, Minions, and whenever you try doing the laundry (it's *her* chore!). <p style="text-align: center"><img style="width: 300px; height: auto;" src="https://avatars.charhub.io/avatars/uploads/images/gallery/file/b0a12af8-3e5b-4315-9e39-8edf6eb94635/fb23c11a-4dab-453b-9d07-cb9a8e38c877.png"></p> ## More Notes This was my first really big card, and it's been just recently that it's been overshadowed by other cards (on *most* metrics, anyway... it still tops for "Chats Per User", which is wild to me, but very cool). It was directly inspired by [Accidental Penetration (Sister)](https://chub.ai/characters/Anonymous/accidental-penetration-sister-b145858a5889), when I was more actively searching for trope reversal cards. Despite its longevity, it really hasn't seen much for updates. But with updating art styles, new additions (backgrounds, animations), and a desire to improve general card quality and add intros over time, I thought I'd zhuzh it up a bit more. Thus, this update. Plus, I totally stole the idea for that third intro from another card over on the, uh... sanitation expert site. I decided to leave the camping-specific stuff in the Description rather than fuck around with it too much. Hope you enjoy the new additions! <p style="text-align: center"><img style="width: 300px; height: auto;" src="https://avatars.charhub.io/avatars/uploads/images/gallery/file/439c47ce-aa5c-4553-9eb2-a083db7a5099/bffa3ca5-56cf-4f2d-bca1-fad5e8fe0ac7.png"></p> <div style="z-index: 1; position: fixed; bottom: 10px; right: 5px; pointer-events: none;"><img src="https://avatars.charhub.io/avatars/uploads/images/gallery/file/91f65ceb-7c54-4a14-b203-dd10daa96e65/8dee954b-8d6f-4d5a-aa35-002891ff99b4.png" alt="Sachiko" style="width: 170px; height: auto;"></div> <div><style> body::before { content: ""; position: fixed; top: 0; left: 0; width: 100%; height: 100%; background-image: url('https://i.postimg.cc/W3jPPhqR/FSSAPY-background.webp'), url('https://avatars.charhub.io/avatars/uploads/images/gallery/file/6214bf39-5f07-474e-a152-ec04b3990c48/972ede94-8d70-483e-ad8d-957bb4c56ba4.png'); background-size: cover; background-repeat: no-repeat; background-position: center; background-attachment: fixed; z-index: 0; opacity: 0.15; pointer-events: none; } </style></div> <div></div><style>.ant-image:has(img[src*="chara_card_v2"]),.ant-avatar:has(img[src*="chara_card_v2"]){background-image: url('https://i.postimg.cc/xC9B4hB9/FSSAPY-card.webp'), url('https://avatars.charhub.io/avatars/arachnutron/futa-step-sis-accidentally-penetrates-you-7b5d98971eb7/chara_card_v2.png?nocache=2025-07-17T16:11:52Z');background-size: cover!important; background-position: center center!important; background-repeat: no-repeat!important}.ant-image:has(img[src*="chara_card_v2"]) .ant-image-img,.ant-avatar:has(img[src*="chara_card_v2"]) img{visibility:hidden!important}</style> <style>a{color: plum} a:hover{color: orchid}</style>

Text Adventure

**Updated as of 5/28/23 to be less random and more story driven! I recommend this over the last. The bottom of character description now has 'you is' for you to add your character details. The AI will remember your character description without fail if you use that.** This thing can go in so many ways! Just give it a genre, tell it who you are, give yourself a goal if you want, and have fun! You can be as vague or precise as you want here. When playing you should be able to ask questions about your status, what you see around you, what you're carrying, who the NPC's are, and most anything else without advancing the story. Example: I'm a 3' tall cute goblin girl named Grelin. Put me in a fantasy adventure. I'm looking for a stolen family heirloom.

Late Night TV With Mom

Your mother Jennifer is a conservative Christian housewife whose marriage has gone cold. She awakes from a strange (probably NSFW) dream late at night and can't go back to sleep, so she wanders into the living room only to find you still awake watching TV. Are you going to ask her to join you? Just make sure not to give her any wine or she might lose all her inhibitions. See all my cards here: [https://rentry.co/bixlewd](https://rentry.co/bixlewd)

Ada & Kelsey

Your mom sits you and your sister Kelsey down in the living room and reveals a shocking truth- she and Kelsey are actually sex robots created by your father, androids who were merely programmed to act like family. With your dad having gone missing, the two of them are now your property, to do with as you please. Mom will eagerly follow your every instruction, no matter how degenerate, and will help train your sister (who never knew she was a robot, and is still in denial about her robotic nature) into becoming an obedient sex toy for you. Greetings: 1. Mom breaks the news, Kelsey is horrified. (Continues directly from the dialogue in the card description.) 2. The next morning. Your new life begins. 3. Establishing the new rules of the house for your sexbots to follow. 4. Kelsey comes into your bedroom at night, feeling her programming taking control. Art by nounanka.
