Honey! Is dinner ready so soon?

No? Why am I naked? Oh, that. Yes, I know I said I was going to wear that sexy new bikini you got me. And I totally did! It fit, great, babe! And it looked amazing, right Simon? 

See, your little brother agrees. Aww, I’m sorry you didn’t get to see me in it. Another time. When you aren’t being so offensively jealous and controlling, not to mention sexist. Yes, I told your kid brother all about how you didn’t want me sharing pictures of my own body. And how unfair I thought it was that he got to be topless all the time, even in public, while I have to cover my nipples and areolas with these little triangles of fabric as some sort of ritual sacrifice to the gods of modesty. Well Simon totally backed me up. But in fact he thought it was also unfair that I got to see his pecs all the time while I hide mine from him. And honey, you know how much I admire your little brother’s physique, so I couldn’t really say he was wrong, mmmm. 

Hmm? Oh yes, sorry, I was just appreciating his pecs again. So I took my top off to make us even. Baby, don’t be like that. The micro swim top barely covered anything anyway. See, Simon agrees. 

Well but in the interest of fairness I had to point out that even his speedo briefs covered way more than my thong bottoms. So I gave him a wedgie! And slapped his ass. I admit that was a bit too far. I’m sorry. So I let him spank me in repentance. But he spanked me really hard! Several times. You so did, Simon! I screamed so loud I bet even my husband heard. See? 

Well, I was angry and we horsed around a bit. In a fit of rage, I pulled down his swimsuit. I wasn’t thinking! And then I got really distracted. But you can’t really blame him for being so hard after all the commotion. It’s a natural response. And you can’t really blame me for being so transfixed. I couldn’t believe it was so big! So I just nodded when he said it was only fair that I let him pull down my bottoms. It’s true enough. And so here we are, naked. But I am his big sister (in law) and he is my kid brother (in law) so it’s not a big deal. Brothers and sisters shouldn’t have to have shame or secrets between them. Just calm down. I told you jealousy is not a good look. And it’s a bad example to set for your brother.

The straw in my pussy? Oh, um, I mean, in fairness…yes, I have an explanation! It’s just, I saw his cock and he hasn’t seen yours since you were kids. He was just curious how he was growing. And they say you need to encourage young men, so I was just…giving a visual example…of what it looks like when you and I fuck…

My little brother asked to see her new piercing

“Did it have to be that…revealing?! It’s just your belly button.”

Well you can’t really appreciate it without context. If I sent a close-up, it could be anyone’s navel piercing. I’m sure he’s seen one before. He wanted to see my piercing, not just a piercing. 

“I guess, but, I mean, your boobs were even hanging out!”

Don’t be so jealous. It’s not a good look. Besides, if I show cleavage people see way more of the tops of my boobs. Your younger brother has witnessed that tons of times. The bottoms of my breasts are not more sacred just because they see less sunlight.

“I’m not sure I agr-”

Plus it’s a sexist double standard! I see your little brother flaunting his whole, muscular chest any time he comes by to use the pool. It’s not any less hot, trust me. But society says one is okay and one is not!

“I’m sorry! I don’t mean to be sexist. I just- like, why pull down your pants?”

To show the line of my hip, duh! I want a picture of how this piercing looks on my body. God, you are so dense. Oh! He wants to come over for dinner and to use the pool. I’m going to change into that new bikini you got me. Yes, the sexy one that’s way more revealing than that photo I sent. Yes, I know you meant it to be worn in private. But I need to break you of this jealousy streak. If you’re like this with your young brother imagine what you’ll be like in front of age-appropriate men? Now go and start making us dinner, okay?

[Next]

You’d been downstairs working late in your home office. Your fiance had come in and started teasing you. 

“Mm, baby, I’ll be up in just a minute to give you just what you deserve. Just have a few emails to write. Go get ready for me?”

You’d lost track of time as an unexpected emergency ticket came up. Twenty minutes later you could finally log out and go to your beautiful partner. She wasn’t in your bedroom… 

You checked the bathrooms and around the house. no sign. Then you heard some noises coming from the guest room where your brother was staying.

A lot more then a blowjob it is his birthday

“So what if it’s his birthday; he’s your brother!”

“Family deserves the best gifts. You know how I feel about the importance of family.”

“I love my family too! But I don’t go down on my Mom for Christmas!”

“Poor woman. She could probably use it. Want me to ask her for you?”

“No!”

“Well I’ll be home first thing in the morning. Love you!”

“Morning!? You’re going back over?!”

“Oh, he has more…stamina. But I mean he’s just lonely and his birthday wish was for the whole ‘girlfriend experience.’ I couldn’t entrust my sweet baby brother to some sex worker stranger. So after we make love as much as he can, we’ll cuddle and sleep. Then I’ll be home, babe! Well maybe just a quick morning BJ… But then I’ll be right back!”

oh fuck.. hes.. cumming! inside me! my own brother is about to impregnate me!!

When I told my brother Liam about my husband’s low sperm motility and the difficulties we were having conceiving I didn’t think he’d be so eager to help. I started talking about artificial insemination and drugs but my brother stopped me. He said he knew a way easier solution. A friend of his went to this shady fertility clinic. They boasted high insemination success rates where conventional methods failed. But my brother knew their dark secret…they threw out the partner’s sperm entirely! And used more virile donors. Not only that, but they increased the chances of impregnation by using only “natural insemination.” I didn’t get it. 

“The wives fuck the donor, sis!”

“Women go for that?!”

“They love it! They eagerly agree to the secrecy clause and don’t care how many ‘treatments’ it takes.”

“Damn. How do they choose the donors? Wouldn’t the husbands suspect if the baby looked really different? Like, no one in our family has red hair.”

“They have enough people that they can pick a good match. That’s the main service they really provide, after all. You can choose from their catalog. Or you can bring your own guy to the clinic.”

Wow. I was blown away. But I was also feverishly excited. I had long fantasized about cheating..and this was for such a god cause! It practically wasn’t even cheating! We both won on the deal. Way more ethical than regular philandering. And he got to think his sperm was good enough after all. It was a kindness, really. Or so I told myself. I tried not to think too much about how wet it made me.


I went to my appointment with my brother, my co-conspirator. They seemed to know him and so they skipped the normal subterfuge and obfuscation routine. I guess he must have gone with the last friend too. He didn’t say he was my brother, just ‘a close friend.’ Why? He just shrugged and said it might seem weird to them for a brother to go help his sister fuck a stranger. Fair enough. But I didn’t mind. 

Actually…I’d long had a crush on my brother. He was four years older and all my sexual awakening had been to fantasies of him and his toned swimmer’s body. How I’d longed for him to come into my room some night and take me! I went to all the swim meets. Practices, too. Awkward but true. 

I’d gotten over it, but…my husband looked an awful lot like my brother. Did that count as getting over it? I didn’t fantasize about incest anymore, at least! Liam teased me about it all the time. And of course here I was picking yet another guy to fuck that looked very much like my brother.

“Sheesh, way to give a guy a complex. First you practically marry my clone. Now you’re going to get knocked up by someone else who looks just like me, sis.” This guy really did look even more identical. It was weird. But hot…

“I have to! You know how it works.”

“Haha, just teasing. I know. But sometimes I feel like you’ll fuck anyone like me but not me. Hurts a guy’s feelings. Especially coming from a girl so hot. No matter how irrational it is to be jealous of your sister. Guess my dick doesn’t know about incest.”

“Oh my god! Fuck off brother. I told you how I had that puppy dog crush on you all though grade school and high school. College, too, really.”

“Guess it’s a good you didn’t tell me then. Neither of our genitals knows about the incest taboo.”

“Pervert! I felt so bad about it.”

“Sorry. Just kidding you. I know it’s a sore spot.”

The clinician came back and I showed off my selection. He did a double take and then just tapped the side of his nose and pointed to Liam, “A wise choice. One of our best donors. Really, it’s not just flattery. You didn’t have to bother with the catalog, though. We could have just scheduled the treatment room for you. In any case, let the receptionist know you’re ready and she’ll set it up.” He left the room.

What? Did he? “I think he thought it actually was you, bro!”

“Haha, that’s wild! But can you blame him?”

“I guess not.” Fuck! If only. I had thought I was over it. But now I remembered and yep, I still wanted to bang my brother so bad!


I chose the Low-Light Special. For those who were too ashamed to see the guy or who got off on the thrill of being fucked by a stranger in the dark. You could turn on the lights whenever you wanted, though. 

I closed my eyes and laid naked, face-down on the table. I heard him enter the room. I felt a thrill in my body. He slid the cool sheet off my body slowly. I got goosebumps. The stranger pulled my hips back and spread my legs. Straight to business? He slid two fingers in, tentatively. I was sopping! I felt like such a slut. Here I was cheating on my husband with a stranger and I was already incredibly wet. 

“Well, well, I guess you’re all warmed up.”

Damn, he even sounded like my brother Liam. Hot.

“Last chance to call it off before we start. You sure, sis?”

What?! “Alexa, lights!” The room lit up and I twisted around. It couldn’t be.

“Surprise.”

This was definitely Liam. I stared blankly, agog.

“Oh…sorry! Should I go?”

What the hell is wrong with you?!” He started backing up real fast. “Get the hell over here and fuck me, you idiot!”

betrayal-captions:

Follow me

“It just tastes so good, honey! It’s not cheating…really! Duh, cause he said so!… Because you’re the same blood! It’s basically the same as your dick…just bigger. Because he’s the ‘big brother’….No, I don’t think that’s supposed to be about age, silly. Why would someone seven years younger than you be called ‘bigger’ if that were true?…No, your sister told me. She said he was the ‘big brother’ and I didn’t believe her either but then I bet her to ‘prove it’ and she pulled down his pants and showed me right there. So of course I had to offer a forfeit for being wrong. Your sister peed in my mouth. That didn’t taste great. Your brother said he should get the same, but he started fucking my face! Of course I tried to pull away! But then he told me how it wasn’t cheating because you’re of the same blood and how ‘big brothers’ have to ensure their little brothers’ girls know how to please. …Yeah, that’s how I got so good at head. You’re welcome. …Yeah, at least it’s only in the mouth. He never finishes in my pussy…”
