Learning the Rules
The following story has yiff in it, which you probably expected since I don't know how else you got to it other than a naughty website unless someone stole this story and posted it elsewhere (in that case fuck you stealing people). If you are under the age of 18 (or whatever the legal age of reading porn is where you are) then you should not read it because you'll get in trouble if you do. I know this won't stop anyone but at least i won't be held accountable (Yay)

Learning the Rules
1.Your new step sister is your mistress now.
What the hell was this list she gave you? The first official day of your new family all being together and you get handed some sick joke on a piece of paper. After glimpsing through the first couple of rules you stop and toss it to the side. Hopefully if you don't acknowledge it she won't try to use the joke anymore.
- Mistress gets to kiss her property whenever she wants.
The second rule you read on that list popped into your head while you were walking with your sister to school that morning. She had attempted... and succeeded in kissing you three times before you were able to get to the school building and rush to class.
- Whenever possible you will eat all meals in the company of your mistress.
Your sister managed to get an empty seat at the same lunch table as you and your friends. Luckily she didn't kiss you in front of them and that gave you some hope she might be giving up on weirding you the hell out.
- You shall not openly show romantic interest in another without mistress's permission.
During one of the afternoon breaks between classes you were chatting it up with your girlfriend when suddenly your sister goes all psycho having appeared out of nowhere. Yelling and threatening she chases your girlfriend off before turning to you and scolding you for breaking one of the rules. Maybe this was more than just some prank, and if so you wish you had read the list more carefully.
- If mistress commands you will show romantic or sexual interest in another.
The fifth rule was one that you remembered a little better and when school was let out she cashed in on it. On her word you went to your girlfriend to clear up the misunderstanding (without saying anything about your sister's position over you or the rules) and invite her back home as a show of good faith.
- Do not tell others about the rules, without permission or unless mistress tells them first.
It was so hard to keep your mouth shut about all this. What if it was a trap? Your maniac sister could do anything when you both arrive there. What's worse is the thought of what she'd do if you got on her bad side.
- When in the house obey mistress's every command unless it has potential to harm someone.
At this point even if you read the rules this far you had forgotten them. It takes a little bit of arguing and some glaring from her before you leave the room and let your sister talk alone to your girlfriend. Right as the door is closing you hear your sister say something about making a copy of the paper from this morning for you to study.
- When in presence of mistress and another, mistress has power to give co-rights to you.
You were a little surprised, but not that surprised hearing about this rule. More shocking was the fact that now your girlfriend was embracing the situation fully now that she was let in on things. You followed orders as you were told to start giving her some oral attention. Your sister had a paw down her pants as she explained she would allow you (via the 4thand 5th rule) to keep going out with this girl because she was fully willing to let your sister run the show as top mistress, and there would be a little re-writing of the rules with your girlfriend as secondary mistress.
- Mistress(both of them now) have full rights over sex with you in private.
You knew your girl wasn't a prude like plenty of girls out there but with this new found power she was showing you just how perverted she could be. Stuffing used panties in your mouth, making you rim both of them and finger fuck them to orgasm, using her footpaw roughly against your shaft and balls until you came all over. She even made out with your sister and told you to spank your cock against both their asses while you waited for the kissing to stop.
- Your cum may be stored in any way desired by mistress(both) for future use.
When they were done making out your sister whispered something to your girlfriend and got out some condoms. They both kept putting condoms on you, started pawing and grinding against you speaking dirty things, and praising you for being a good slut pet whenever you came before replacing the condom and starting again. After more times than you thought possible you finally stopped being able to fill them but the two girls just did it to you some more forcing a few dry orgasms to make sure.
- If you don't refer to mistress(both) by (their) title in private then you may be punished.
As you lay in your bed exhausted from the sex you say something to them about maybe being able to adjust to this strange new setup and relationship with them. They shared an evil smile as you had apparently used their actual names instead of the title mistress. That allowed them to punish you as they see fit.
You wake up in your bed, naked and sore from the afternoon.... evening.... and night before. The two girls aren't there but you see a list on your desk. It was multiple pages paper clipped together obviously having been thought up the entire time you were asleep.
New Rules
- Your step sister and girlfriend are both your mistresses now.
Considering how much happened to you because of the first list which was a single page you were scared and excited what the new rules would bring. This time you knew it was real though, this time you would learn the rules by heart like a good boy.
