Okay but like, I kinda want a little brother to bully rn..🖤🖤

[pinkiepawz]

big brother that gets me really really high so i cant push him off when he begins to grope me >_<

[tomis-problem]

I think Ashley should forcefem Andrew

I think she should dom the fuck out of him and make him wear her panties and her fem clothes, then take pictures of him and use them as blackmail to do it more. Rinse and repeat. I think she should peg him and call him a good girl.

And i think Andrew should let her bc she’s his cute little sister and he’d do anything for her <3

Oh no... We are retarted.

Guys, remember to create more incest fanarts!

And someone who can create meme and can't separate fiction from reality created something like this:

Little fix: Creator of this meme "probably" refers irl incest. I'm not sure. But who stupid ships real people? Especially incest? (I'm not into RPF, but I'm okay with that, but now, I'm referring to this meme and irl incest)

"You don't wanna hurt me But see how deep the bullet lies, Unaware, I'm tearing you asunder, Oh there is thunder in our hearts..."

"Tell me we both matter, don't we?"

Q: Where are prompts listed? A: They will be posted here on Tumblr with the tag #microcest prompt

Q: The day for the prompt has already passed. Can I still write a microfic? A: YES! You can still submit a microfic for any prompt that has passed, just note the original prompt date in your submission.

Q: Will you reblog my post? A: Yes, we will reblog every microfic that tags this account. Give us 72 hours to have it reblogged before reaching out to us about it. If we still have not reposted it in that time, then please feel free to DM or send us an ask about it.

Q: How should I incorporate the prompt into my microfic? A: Feel free to use the exact word/phrase in your work, or just use the prompt as a general idea. (Example: if the prompt is ‘not in the swimming pool!’ then you can use that as a quote from one of the characters, or simply write about a scene where something ensues that maybe shouldn’t be done in a swimming pool.) Q: What is the word count requirement? Does my microfic need to be a specific number? A: Microfics are generally anywhere between 50 and 500 words, but if you feel inspired to write something longer, then we encourage that as well!

A Morning

I love when my big brother wakes me up by eating me out. I’ll be almost there to waking up and my dream will turn sexy. The slow licks of his pierced tongue drives me crazy. It starts to get me hot and bothered. The feeling of his tongue piercing rubbing against my clit while start waking up fully. Oh god, the way he’ll stare until I open my eyes and look back at him with my legs hooked over his shoulders. The sounds are obscene from how fervently he’ll start lapping at my cunt once I’m fully conscious and looking at him.

“Princess” my big brother will purr at me. His voice is so deep and gravelly in the morning.

He won’t even give me a chance to respond before he starts sucking on my clit. It always pulls a whimper out of me. It feels so good. It feels good to have his warm, wet tongue eating at my soaking pussy. My big brother likes to surprise me. Sometimes he’ll insert a few fingers, other times it’s my dildo.

Yesterday, it was my dildo and it felt so good. I was so wet, we didn’t even need lube. He kept sucking on my clit and he thrusting my toy inside. It was everything. I felt like I was melting, I could feel my heart race and the hot coil inside me tighten impossibly tight. The pleasure is so overwhelming it always feels like I’m drowning in it. I have to pull his hair and it makes him groan every time. He thrusts the toy inside faster, being sure to brush against my g-spot until my legs are shaking. It’s impossible to keep myself from cumming as my body feels like it’s burning up completely. I’m a mess afterwards, always, but he kisses me. My big brother kisses me with my slick still on his lips.

Dreams

My big brother and I got to talking the other night in bed. He was petting my hair and rubbing my back. I was telling him about my therapy homework. So I told him what I wanted. I want a cottage in the woods far away from the taboo of being in love with him. I told him that I want a live somewhere snowy with a fireplace and a dog. He laid on top of me and enveloped me with his forearms on either side of me just like the very first time we had sex. He kissed me and hugged me close. And he told me that while we’ll never be able to marry, we won’t get in trouble in New Jersey. I told him we could get a handfasting. He whispered to me that once he finishes college and gets set up with a decent job he’ll buy me that cottage and let me be his stay at home bride. I didn’t mean to but I started crying. He really is my everything❣️
