This is a simple, one off story, written just for fun.
The spelling and grammar are UK standard. Some of the tenses jump a bit, and I'm sorry, but it was unavoidable.
All characters in both stories are over 18. (You'll understand about 'both stories' later)
Please don't judge me on the first 10 sentences. It gets better. I promise.

WRITER'S BLOCK
---
Her big round boobies jumped up and down like fat kangaroos as he pushed his big sausage meat stick into her small vagina hole.
"Oh, that feels so good inside my pussy! I love sexual intercourse so much! Especially with anonymous strangers like you!"
"Yeah!" He replied. "I love how big your breasts are. They are like balloons of fun. It is great you are only 18!"
"Now ejaculate inside me!" She instructed him, "It will feel so good when men put semen into my vagina!"
And he did. And they both felt so good. She felt a big orgasm.

"Daniel! What on earth are you writing on your laptop?"
It was my own fault, really. It was my brother's private laptop, left in his private bedroom. But he had left the door open with the writing app on screen. I just imagined he was writing some university stuff. I was curious. Maybe he'd need his big sister's help on some dry, boring essay. I never expected...this.
Daniel came rushing out the bathroom, shower water dripping on the floor, his towel being frantically pulled up as his hands reached out to close the laptop.
"Fuck you Sis! You can't just go barging into other people's rooms!"
"You left the door open and the laptop screen on. I was nosy. Sorry. But anyway, what is this shit are you writing?!"
"Nothing! Fuck off!" His clothes were fully back on now, and his hands were now on my arms, 'encouraging' me to get out his room.
"Because it looked..." I said more calmly, "...like badly written erotica."
"...it's not badly written.."
"It is." I said gravely, lowering my head. "VERY badly written."
"How would you know?"
"Three reasons. First - I'm an English Lit graduate. I'm writing my master's thesis on the overuse of 'the hero's journey' in twentieth century literature. I know bad writing when I see it."
"...Fine," He conceded.
"Reason number two - you compared her breasts to fat jumping kangaroos."
"And? Breasts jump. Kangaroos jump."
"Breasts don't jump like kangaroos jump. Breasts jump like..."
For a moment I had to think back to the last time I had a good hard fuck. A really good fuck. Sadly, too long ago. Not my most recent ex. He was a great boyfriend, terrible lover. Two minutes was an achievement for him. No, probably that tattoo'd guy I met at the club three months ago. I remembered how my breasts rose up and down when I was bouncing on his big dick, or how my boobs danced forwards and back when I was on my back on the kitchen table and he was slamming into me. The pleasure between my legs when he...
"Hello? Earth to Sis?"
"Breasts bounce like creme caramel. But, how come you don't already know that?"
My brother went bright red. I knew he was only 18, but he was handsome, sporty, and extroverted. He couldn't still be..a virgin?!
"Shut up. You said there was a third reason."
Now I was the one feeling embarrassed. I shouldn't have said there was a third reason. Two would have been enough.
"I'm waiting." he teased when I didn't say anything.
"Fine. I know, because I've written erotic stories too in the past. So I know good stories when I read them."
"You've written erotica?" he said with a mixture of both disgust and intrigue.
"I average 4.81 feedback. I even won a writing contest once. Where do you think the money for that new handbag came from?"
It was true. I wrote a story about a mother and daughter, alone on an abandoned spaceship. I won second prize for the sci-fi / incest category.
I expected Daniel to mock me at that point. I expected him to throw me out of the room and delete his story forever.
I did not expect my little brother's next words.
"...teach me how?"
I thought hard for a moment. Why not? We were both alone in the house. Mum wouldn't be back for a few hours. And he did need my help with this story. Sure, it would be a bit weird, talking sex with my brother, but nothing I couldn't handle. Might even be fun.
"FINE." I said with a 'huff'. "Let's start at the beginning. Tell me the story."
"Well.." he said slowly, not quite believing he was talking about it, "It's about a man, who walks into a young woman's bedroom accidently. She's naked. She sees him, and thinks he's hot. So they have sex."
"That's.....terrible." I told him honestly. "Why is this random guy in her bedroom? Why isn't she surprised? Why is sex the first thing on her mind, instead of ' Who the fuck is this stranger'?!"
"OK" he said, annoyed at my criticism already. "What would you write?"
"Well", I said slowly, thinking of the situation in my mind. Imagining as if I was both the man and the woman. Trying to think of a legitimate reason for the sexual meeting.
"Maybe he's not a stranger. Maybe he's someone she knows well, but has never had sex with her before. Like a housemate?"
"But she's only 18." Daniel said, defending what little remained of his original idea. "Why would she move out of her parents' home?"
"Fine. She's still in her family home. So the man is her step-brother or step-father or something."
"Why step?"
"Well, some websites don't like incest. So it gets around that block. Plus, the taboo of incestuous attaction is usually too strong. People don't normally wake up and think 'oh, I want to fuck my brother'."
There was silence between us for far too long. I shouldn't have said brother! I should have said uncle or something.
"Oh" he replied slowly, breaking the tension. "That kinda makes sense. OK. So it's a step-father and step-daughter. But why do they have sex?"
Now he was asking ME for the story!
I thought deeper, imagining the situation. Imagining I was the girl on the bed. Sleeping naked. My father..I mean stepfather..walks into the room.
I felt a twitch between my legs. A tiny spark telling my brain what my body was already doing. I was getting turned on by the imagination of it all.
"How's this? The daughter, she's fantasized about her father..step-father..for as long as she's understood sexual feelings. But she was too young before. But now she's 18. And her mum is away for the weekend. She's alone with her father for the first time, and she wants to seduce him."
"That sounds good!" Daniel said, rushing to sit down on his computer chair, his towel still wrapped around himself after the shower. And..was he trying to hide an erection?
I watched his hands typing the backstory quickly, only speaking to suggest a synonym or grammar change. I felt the room getting warmer, and took off my jumper.
"OK, so now she's in bed, sleeping naked, but her step-father isn't coming into the room. What next?"
"Let's write as 'father' and we will put the 'step' part in later. To save time." I told him. "Plus pure incest stories get more readers. Trust me. Anyway...maybe she called out to him, saying she had a bad dream? Or a medical problem?"
"Yes! That's great!" He said excitedly. "She calls out, saying she has a pain in her chest."
He wrote the next few lines. He read them out loud for me.
"Her father rushed into the room, worried about his little girl, and the heart attack she was feeling. He burst open the door, almost pushing it off its hinges.
His daughter was looking healthy in the bed, her bed sheets covering her below the waist. But he could see her exposed breasts. Her beautiful breasts, like..."
Daniel stared at me. At my t-shirt. At the bra-less breasts beneath it. Then finished typing the sentence.
Her beautiful breasts, like large marshmallows.
"My breasts DO NOT look like large marshmallows!" I said angrily.
"I...um...I mean.." he said flustered, his face going red. He reached over and closed the lid on his laptop. "This was a stupid idea. I'm sorry."
I felt bad for him. He was trying so hard! And I'd upset him.
I turned around, shutting the door of the bedroom. I knew we were alone in the house, but I wanted to be double sure we were alone.
I carefully took my t-shirt off. My boobs bouncing as the last part of the fabric released them. He just stared.
"Well..? Get back to writing!"
He re-opened the laptop, writing again about the girl's breasts. Somehow his words made me feel proud of my own breasts, the inspiration for his description.
Her perfect breasts mesmerised her father. He couldn't look away. Their soft curves, the way the bedroom light reflected off the top, but created sexual shadows beneath. The way they seemed to rise and fall slightly with every breath she took.
"Daddy, I've got a pain in my chest. Can you feel my heart? See if I'm OK?"
