Stop 15: A Secret I Will Keep

You pulled the covers over your body and lifted the book to your head, getting engrossed instantly. Only a year ago had you been barely literate and then, suddenly, you were reading books by the cartful. It was a respite from it all.

Marine, your older sister, walked in nothing but a shirt and underwear, climbing onto the top bunk. Your now barely prepubescent body, just starting to truly appreciate the majesty of the female form, ogled as she slowly lifted herself up. She leaned over the side, her braless breasts dangling like heavy, jiggling sacks of meat.

“What are you doing?” she asked in her usual playful tone

“Reading.”

“For school?”

“For fun.”

“Is it weird stuff?”

“Weird stuff?”

“You know…” her voice became coy and seductive “like hentai.”

You rolled your eyes.

“You mean those nudy manga you have? No.”

“Boring~!”

“Whatever.”

The lights automatically dimmed, the only one left being the one on your nightstand. Marine shifted above you repeatedly, as though she were struggling to find a comfortable position to rest.

“Marine, can you quit with all the moving? I’m trying to read here.”

She simply huffed. After no more than thirty seconds, she hopped to the floor, going to your shared desk to retrieve one of the hentai mangas she’d recently smuggled in the door. If your parents found out she had it, they’d put her head on a pike. You and she had an unspoken agreement that if you kept the hentai a secret, she’d not tell about your recent curiosity in dolls for girls. An innocent hobby, but one your trad parents would reject all the same. Marine suddenly got a coy look.

“Scoot over.”

“What?”

“Scoot over. C’mon. I want to snuggle.”

“But why?”

“Because I told you too. Now move already.”

“Fine, fine.”

You pushed to the side and Marine got in with you, twice your size and able to fit you comfortably inside the opening between her breasts and knees. It was as though she were pregnant with you and she certainly gripped you in the tender manner with which a mother holds her child. It was oddly comforting, safe even. Marine was, if nothing else, an amazing cuddler.

“Let’s read a real book tonight. A big kid book.”

“What, you mean the hentai?”

“Yeah.”

You looked away. Part of you was certainly starting to develop a curiosity, but doing it with your sister was like taking a bath with your dad. It wasn’t hot, just gross.

“Sit up on my lap.”

You both shifted position, with Marine leaning against the backboard and you laying between her legs. She gripped your chest as though she were trying to locate boobs you didn’t have, tenderly searching for the slightest bit of fat to latch onto.

“Stop…”

Marine let out some giggles.

“Why, hm? Why?”

You swatted her hand away.

“Because it feels weird.”

“Comfortable?” she asked, wrapping her arms around you and pulling you deep into her breast

“I think? I dunno.”

“You’re just nervous. Let’s read.”

Marine flipped open the manga titled “A Secret I Will Keep.” On the cover it showed an orange haired woman with comically large breasts holding a young boy cradled in her arms like a baby. She flipped to the first page. It started simple enough, the two both wearing clothes and exchanging dialogue. The woman appeared to be fifteen to seventeen while the boy no older than seven.

Welcome home brother! the woman said

Thanks! he said I’m going to go take a shower. It’s been a long day.

Marine’s finger traced along each line to hold her place and she began to exhale hot breaths on your neck. Her hand rested on your belly, gently squeezing it.

The boy went upstairs into the shower, taking off all his clothes and exposing his hilariously large penis. Despite being so young, he was hung like a horse. It made you feel self conscious, something Marine quickly picked up on.

“Hey?” Marine whispered

“Yeah?”

“How big is yours?”

“Mine?”

“You know…” she moved her hand down to your crotched and gently tapped twice

You nearly jumped, feeling a large slap of sensation as she inadvertently tapped the head of your penis. Only recently had you been getting erections and had yet to get used to the strong stimulation, especially when it was done out of nowhere.

“H-hey!”

“Well?”

“Well… I’ve never measured…”

“C’mon. Just gimmie a guess.”

“Like… six and a half inches.” you lied

Both you and her knew it was a huge lie yet, all the same, the idea that you were well endowed got Marine into a tizzy.

“So big~ must make all the boys in the locker room jealous.”

“Does that ever happen to you?”

“What do you mean?”

“Girls in middle school change in locker rooms, right?”

“Yeah.”

“Do you ever get boners?”

Marine put her hand over her mouth to keep in a laugh.

“No. Girls don’t have dicks.”

Something about her saying “dicks” instead of “penis” shocked you. It was like hearing your mother casually say “fuck.”

“You don’t?”

“No. I wish I did sometimes. They’re so weird.”

“What do you have?”

“Let’s read and you’ll see.”

Marine flipped to the next page, feeling her vaginal walls began to open and moisturize. You kept your eyes focused on the protagonist's penis, envying such a sizable hog. The door to the bathroom flew open as the sister absentmindedly came in to drop off new clothes for her brother. Her eyes bugged out, seeing him completely nude. The shot then closed into her mid face as she licked her lips and smiled.

Why don’t you let me help you out? Remember how we used to bathe as kids?

That was when we were kids though!

It’s only weird if you make it weird.

While the sister stripped, the protagonist reacted in typical over the top anime fashion, complete with nose bleed and overly exaggerated slapstick body language. Marine turned the page and your eyes became glued to it, observing every detail only to find yourself disappointed with the mosaic censorship so common in Japanese smut manga. Marine licked her lips in similar fashion as the sister in the story, enjoying your displeasure at being denied an uncensored view of 2D pussy.

On the next page, the sister sat behind the protagonist, pushing her boobs into his back with a juicy squeeze. It was here that you finally began to poke out through your pants, your more modest sized hog becoming hard as stone as you felt your own sister’s soft, pillowy breasts on your back. Marine pulled you in slightly tighter, giving you the full sensation of her breasts pressing on your back. You felt her eyes wander onto your crotch and you hunched slightly.

“Awww~ don’t hide it. It’s not small.” she chuckled

“Shut up…”

She flipped to the next page and the sister began to wash the protagonist’s back, gently and thoroughly getting every part of his body.

“What a good sister she is. You know, I could do the same thing. I’m a good sister, just like here.” she gently put her lips to your ear and whispered “would you like that? Would you?”

Marine chuckled softly and you felt butterflies course through your entire body in a grand eruption. It was brief, but for a moment you imagined it: your sister, naked and wet, rubbing every inch of your body, getting lower and lower until…

You cleared your throat and looked off to the side, your face growing hotter and redder by the moment. Marine pretended to switch positions, secretly using it as an opportunity to hump you a few times.

The story continued in the usual hentai fashion. No stop followed by th-this doesn’t feel that bad… and ending with an eruption of sperm more akin to a flood of mayonnaise than an orgasm. Both you and Marine were visibly hot and bothered. Your sweat mixed and Marine’s hot, steamy breath, nearly in a pant, slammed into your ear.

“You know,” she breathed seductively “I can show you the uncensored version…”

“Really?”

“Yeah. If you show me yours, I’ll show you mine. It’s only fair.”

“But… that’s weird…”

“It’s only weird if you make it,” she said, repeating the line from the novel “Now c’mon.”

You pulled away from one another and Marine, with surprisingly little hesitancy, began to undress, pulling off her pants to show you the grand prize. It looked so alien. All you wanted to do was touch it. Inspect it. Why were the lips redder than the skin around them? Why did it look so… sticky? And why was that stickiness somehow enticing…

Marine’s chest began to rise and fall heavily, getting more horny the more you checked her out. She loved it. Her brother’s eyes looking at every square centimeter of her pussy, wanting nothing more than to dive head first into her opening. She felt a slight tremor at the thought.

Just as you began to put your face into that beautiful organ, your rational mind hit you over the head with reality. This was your sister. You were lusting after your sister. You felt overwhelmed with disgust and pulled back, getting up out of bed and leaving the room.

Marine sat there dejected, yet still horny. Too horny to even think of the disappointment that accompanied your sudden coldness. As you closed the door, she sat on your pillow, turning her dime and leaving a large gift all over the pillowcase as retaliation.
