Madelyn’s Slut Diary – Day 1

I don’t want to write anything in this. I’m not a slut. I don’t need “treatment”. It’s not fair and I want to go home.

But I guess if I don’t write then Uncle Sean is going to punish me – or have Avery slap me again. Avery doesn’t slap hard but I hate that Uncle Sean is making her slap her own sister.

So I’m supposed to document every time I become aroused, every time I have a sexual fantasy, or every time I engage in sexual activity. That’s so gross, but Uncle Sean is going to make me do it.

Okay.

So I’ve been feeling really awful because Logan uploaded that disgusting video of me to the internet and now everyone thinks I’m a slut. So when I looked at my phone this morning there were like fifty messages calling me a piss-drinking whore, and I wanted to cry. And sometimes when I’m sad I… play with myself, a little, to make the sad thoughts go away. So I guess I masturbated a bit this morning, to try and forget that people think I’m a disgusting slut. Doesn’t everyone do that? It’s totally normal for a girl my age.

Except it just made me feel sluttier and more guilty.

Avery’s looking over my shoulder and telling me I need to say what I was fantasising about when I masturbated, because I must have been thinking of something. So okay, I was thinking about another influencer – a guy called Daniel Brunelli. He’s Italian, I think, and really hot. I was… I guess I was thinking about having sex with him. Lots of girls do, probably. He’s got these amazing abs, and a dreamy face, and I just know kissing him would be super-hot.

Anyway. Then, later, when Great-Uncle Benjamin and Uncle Sean were taking me away from my house, Uncle Sean used his “female instinct gun” on me and my mind went funny. I got wet for no reason at all. I wanted to masturbate. And I wanted to please Uncle Sean. The idea of him being happy with me was sexy. I kissed him on the lips and I stroked his… his penis through his pants, because I wanted to make him happy.

I got wetter when I felt his cock get hard in my hand, and then I told him to slap me, and the idea of him slapping me made me wet too.

None of this was my fault! They weren’t my thoughts! Uncle Sean’s weird mind control gun made me do it.

Then he told me to wet myself and… I did. And it felt sexy to do it. I knew it was perverted and that it was humiliating but… it felt good to humiliate myself. Like I deserved it. Like I’d been lying about being a good, nice girl, and pissing in front of Great-Uncle Benjamin and Uncle Sean was coming clean and telling the truth. It felt like a relief.

And when Uncle Sean told me to take off my wet pissy panties, that felt good too, like I shouldn’t be wearing panties. And when he put them in my mouth and I tasted my piss it was so gross – but it felt so good too, because I knew I deserved it.

I mean, I didn’t know that. I don’t. Because I don’t deserve it. But the stupid brain gun made me think I did. Those weren’t my thoughts.

And then I was sitting in the limousine and I was gagged with my pissy panties and Uncle Sean made Avery play with my pussy. And I couldn’t do anything to stop it because I was helpless – but that somehow made it feel even better, because I had a man looking out for me and telling me what to do and giving me the discipline I needed.

And Avery was really good with her fingers. It was really embarrassing. She shouldn’t be so good at making a girl feel good. I guess she practices on herself.

And then I guess I orgasmed from Avery’s fingers, despite the gross gag in my mouth. I know it’s really disgusting that I let my own sister make me cum – and while I was tasting piss in my mouth, too – but I didn’t have a choice! I couldn’t control my body, because I was strapped down and gagged, and I couldn’t control my mind, because of Uncle Sean’s device.

When we got out of the car, Uncle Sean made Avery taste my pussy juices on her hand, and that was so embarrassing. I tried to stop being wet, but I just couldn’t. I guess that gun was still working on my brain, maybe.

And then he made her take off my skirt and push it up my pussy. And I guess it felt kind of good to have my pussy stuffed like that – but really embarrassing too.

Then Avery told me I had a really beautiful cunt, and I know Uncle Sean was just making her say it, but also I could see she meant it, and that was kind of nice. Avery is such a sweetie.

After that there was the whole thing where Great-Uncle Benjamin told us our new rules for this house, which are so disgusting and completely unfair. And I don’t need to write about that because nothing about that was sexy and I hate it.

And then in our new bedroom we took photos of each other nude for this diary, which was embarrassing and I hated it. I can’t believe I took a photo of my own sister’s cunt. At least she has a cute pussy.

And then Avery kissed me and I guess I was just confused from everything that happened because my pussy was a little wet. It wasn’t from kissing Avery. I wouldn’t get aroused from my own sister, not unless Uncle Sean was using his brain gun on me. I’m not a slut. She’s a good kisser, though.

And after all of that we had to get dressed for dinner, except Uncle Sean only gave us a set of lingerie, and a T-shirt that said “DADDY’S GIRL” on it, and we had to share them between us.

We’re both mostly the same size so we could have worn them either way. My tits are a bit bigger than Avery’s so the bra might have been a bit tight on me, but I could have managed.

But I couldn’t let my little sister go to dinner with no panties, so it was my duty as big sister to give her the lingerie, and wear the shirt myself. And I’m writing about that because when I looked at myself in the mirror wearing only the shirt, I had a brief thought that if Daniel Brunelli saw me like this, he might want to have sex with me, and that made me a little wet.

But he would probably also think I was an enormous slut.

I hate it here.

Avery’s Slut Diary – Day 1

OMG today has been so embarrassing but so sexy!

I finally have a daddy! Uncle Sean’s going to be our new daddy and he’s got an amazing house and I’ve got a cute bedroom that I share with my sister and cute lingerie and he’s going to discipline Maddy to make her less of a slut! Although I don’t really mind if she’s a slut if it makes her happy – but Uncle Sean says she needs to be humiliated and punished for it, and I’m sure he knows best.

So I have to write everything sexy that happened. Which I guess started when Great-Uncle Benjamin and Uncle Sean came over this morning and when they came into the house they called me “sweetie” like I was their daughter and that felt really good. And then I swear they were both looking at my tits while they waited for Maddy to come downstairs.

It felt so good! I’m always embarrassed because my tits are smaller than Maddy’s. The boys at school say Maddy has udders, like a cow, but I’ve just got little boobs. I mean, I guess they’re bigger than some other girls I know, but they’re not huge like Maddy. So when I saw my Great-Uncle and my Uncle looking at my tits like they were turned on it made me feel so good! I’m glad they like my tits!

And then we learned that we were going to live with Uncle Sean, and Maddy was kind of a bitch about it, so they used the device on her that Logan used at the bar, and it made her go all funny. Honestly I kind of like her like that – she looked more happy than she has in ages.

They made her kiss Uncle Sean and stroke his penis through his pants. I was so jealous! I wanted to kiss my new daddy too. But apparently I’ll get to do that every day now so I guess it’s okay.

And then they made her wet herself – right there on our front lawn! It was so funny! Normally Maddy would have been so embarrassed but because of Uncle Sean’s device she actually liked it. I wish they’d made me do it too. No one was really looking except for family, and it would have been so cool and weird to just piss in public.

And afterwards they put her wet panties in her mouth, like as a gag. And I guess at that point I felt a little wet in my pussy. I don’t know why. She just had this expression on her face like what was happening to her was the sexiest thing ever. The boys at school say girls who drink piss are piss-sluts – so I guess my sister is a piss-slut? She pissed in a glass at that bar with Logan, and fed it to that girl who was there, and then I saw that video where she drank Logan’s piss in the toilets. Nice girls don’t do that, I guess. Just piss-sluts.

I’ve never tasted piss before but it made me kind of want to try. Maybe I’ll see what my piss tastes like next time I have to go. I wonder if I’m a piss-slut too?

In the limo Uncle Sean told me to play with Maddy’s pussy. He said I was doing her a favour. Maddy seemed to like it because she was super wet. And it made me wet too. I’ve never really touched another girl there, but Maddy was really soft and her clit is a little smaller than mine and her wetness made her feel all velvety.

I liked making her happy. I know it’s wrong but I don’t see why. I love my big sister and I just want to make her feel good.

I think towards the end Uncle Sean’s brain gun was wearing off because she started to blush a lot and wiggle a bit, but then she orgasmed so I guess she still liked it. And I don’t think there’s anything wrong with doing sexy stuff to Maddy even if she’s saying she doesn’t want it. It’s just for fun, like a tickle fight or a pillow fight. Sisters are allowed to fight and struggle and do things to each other. It’s all just for fun.

Plus Maddy looks really pretty when she’s embarrassed.

When we got out of the car Uncle Sean made me taste Maddy’s wetness on my fingers. She tasted so good! I wanted more, which was good because Uncle Sean made me keep wiping my hand on her and then tasting it. He made me tell her she has a pretty cunt, which is just the truth. And then afterwards I had to push her skirt up her pussy, which was a fun prank. I kind of want to push my clothes up my own pussy now and see what it feels like.

Actually during that Uncle Sean kind of suggested he was going to make me lick Maddy’s pussy. And when he said that I got so wet, because her pussy tasted so good and I knew I could make Maddy feel amazing, and I know it would have been super slutty and wrong, but Uncle Sean thought it was a good idea so it must have been okay. But then he changed his mind, and I was really disappointed. I hope he makes me lick Maddy some day.

The inside of Uncle Sean’s house is amazing! There’s art of pretty naked women everywhere, including my mom. My mom is so gorgeous, and she’s even prettier when she’s nude (even though she doesn’t normally let me see her that way), and in this photo she has men’s cum on her and it makes her look even hotter. I know girls shouldn’t get wet from looking at their own mom, but most girls don’t have moms who do porn, so it’s okay for me, right?

There’s sexy magazines on the coffee table. I wonder if I get to read them?

Great-Uncle Benjamin explained all these new rules for us, and a lot of them are kind of harsh, but they’re probably for our own good. Particularly for Maddy’s good, to help her stop being a slut. But they’re not all bad. We get to call Uncle Sean “daddy”, which makes me feel really good. And we have to kiss each other all the time, which will be fun. I got a little wet at the thought of tongue-kissing Uncle Sean and Maddy every day.

I got to try it out in our new bedroom! I kissed Maddy on the mouth and she must have really liked it because she kissed me back, and I’m embarrassed because I got so wet, like I just wanted to play with my pussy right there, and I know girls shouldn’t get wet from kissing their sister but I couldn’t help it because Maddy is so hot, and she wasn’t wearing any clothes. And I’m going to get to do that every day!

Oh, and I got to slap Maddy a bunch of times! I know that was mean, but Uncle Sean told me to, and I didn’t hit her too hard. And it was so fun! If I hurt Maddy in front of mom, mom would send me to my room, for sure, but Uncle Sean told me I was a good girl for slapping her. And Maddy looks so cute when she gets slapped, like all shocked but also kind of sexy. Uncle Sean says I can slap her any time she’s behaving badly, so I’m going to look for chances to do it again.

Anyway, it’s about time for dinner. We just got dressed. Uncle Sean bought us these cute clothes and we had to decide which of us was wearing which. Maddy’s wearing the shirt, which is funny because her tits are a little too big and they stretch it out so it doesn’t come down as far as it should, so it barely covers her cunt!

I think on me it would cover more, but I think it’s funny that Maddy is going to show Uncle Sean her cunt at dinner, and anyway I wanted the cute lingerie.

I wish Uncle Sean would just make Maddy go naked all the time. I like looking at her tits and pussy. They’re so sexy.

I hope Uncle Sean likes me….

No, wait, I need to get this right!

I hope daddy likes me in my lingerie.
