<div style="background:rgba(90,240,150,0.7);margin: 5px auto;width:80%;padding:1em;border: 2px solid rgb(90,240,150);"> &#8634;&#xfe0f; <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>
