Card requests are CLOSED! I have enough new card ideas to do me for years, and that includes on FutaForks. Intro requests on existing cards are still fine, though.
UPDATES
Oct 7 '26: YTB remake is finally done! That will likely be the last big effort card this year. Also, due to the high volume of people asking "hey, when is thing gonna be done??!??!", I'm no longer comfortable saying what I'm going to be working on next. Those questions tend to slow progress rather than accelerate it, which I'm sure nobody wants. I'm working on something, and you'll see what it is when it's done.
Unfortunately, postimages shit the bed on my animated card and background images, which means I need to migrate them all to another host and update all the cards. You may have noticed I've already started doing this. Unfortunately, this means spamming your Timeline. Terribly sorry about this, but I don't wanna leave all those images broken and there's no option for silent updates on this site or I'd do that instead.
About Me
I primarily write NSFW, OC, slowburn, anypov, dramatic futanari incest cards with a good mix of romance, angst, and smut for high-powered models. I specialize in dual-character hurt/comfort cards that have significant narrative bite, but I typically don't do stuff like hard NTR, SA, torture, self-harm, or underage, although these may appear in backstories.
If you like my stuff, please follow me and rate/review my cards!
I don't have any set schedule for releases. New cards take a lot of time and effort (especially with gens and testing)—even the simplest card takes me about a week to make (roughly 16-24h spread out over a week). Also, I like going back to my older cards and updating them with new intros, plus there are still a bunch of cards that haven't been brought up to the current standard of quality. All in all, I wouldn't expect to see a new card any more frequently than once a month. Conversely, even if there are no new cards in two months, that doesn't mean I'm retired, just... slow. I'm also currently going through a major health issue that's slowing me down considerably. Be patient with me.

Rentry / Where I put my FAQ, a little more info about me, commentary on some of my cards, and links to my retired cards. If a card has gone missing, look here!
The Aubergine Emporium / Ask me questions, make requests, send hate mail (short form)... all anonymously, if you like!
FutaForks / My secondary account, dedicated to forks adding futa to cards and/or cleaning up futa card content.
arachnutron@proton.me / For stuff that won't fit in The Aubergine Emporium, or you would rather keep private.
BotBooru / Card backup account. This won't ever be a target site for exclusive content, but the backup is nice.
_wdcs (We Do Cool Stuff) Discord / Where I spend most of my online time yelling at clouds and/or telling the kids to get off my lawn
Like my cards enough to leave a tip? Please take whatever money you were going to give me, and give it to the charity of your choice instead. They need it more than I do. If you're having trouble choosing one, check out the Awesome Socks Club.
Active Straw Polls:
- Do you prefer narration with asterisks or without?
- Do you like the 'More Notes' section of the Creator's Notes?
- Do you care about futa pussy in bots?
- Do you like animated background images on cards?
- Do you want music in intros?
- Bulges in "SFW" intros?
PSA: I delete comments I don't like, whether you think they're 'constructive criticism' or not! Trans/homophobia, racism, violence against characters (including your persona), and personal gratification posts also tend to get nuked. Finally, I tag NTR according to this guide—if it's not cheating on a romantic partner, it's not NTR, don't at me. Don't like it? Block me!

**Update April 20 '25:** I'm going to retire this card soon! With all of my new intros going into the [College Edition](https://chub.ai/characters/arachnutron/futa-step-sis-moves-in-college-edition-f1045b25fc48), it doesn't make much sense to keep this one around as it's pretty redundant. It's just going to move to Unlisted (because of the delete bug), but if you don't want the hassle of navigating to an Unlisted card and really really want Sachiko in high school for some reason, grab this soon?

- Sachiko

The ongoing adventures of Sachiko, your futanari step-sister, continue! This time, it's the end of the school day, and it's your and Sachiko's turn to clean up the gym storage room. Because the doors for these things are ridiculously designed, you end up locked inside! What you don't know is that Sachiko has a strict wanking schedule to keep her sizable balls drained, and that she always goes straight home after school so she can empty her nutsack before homework, and now she's... uhh... a little uncomfortable. Will you be able to get out before it's too late, or will she be able to find some way to unleash her titanic load without you noticing? Or maybe... there's a third option?
