Helping Big Sister Out
By ??
Michael Fisher (Mike to everyone but his 5’th grade school teacher) sneaked a peek into the partly opened door of his big sister’s bedroom. At 12, the boy was just starting to get interested in girls, and lately had developed a habit of spying on his big sister (Big sister being relative. Mike actually outweighed his older sister by 5 pounds. Julie was only 10 months older than Mike.) In spite of their differences, Mike loved his big sister, and would have done almost anything for her.
Today, the boy was in luck. Julie had just returned from the shower, and was laying naked on her bed, reading. For several long minutes, Mike looked at his sister’s developing body, taking her in, from her lightly rounded little ass, to the pert little bumps that were, at the moment, pressed into the furry bedspread. Each time the little girl shifted position, Mike would get a glimpse of another part of her delightful body.
Soon, the boy’s penis was tenting the front of his shorts. Mike was wearing shorts, and not much else, as it was mid-summer, and 85 degrees outside. For somewhat the same reasons, Julie was in no hurry to get dressed, and swelter in her clothes again.
After reading for about 15 minutes, during which time Mike was unable to draw himself away from the door, Julie started to get bored with the book she was reading and turned over. As she did so, Mike was treated to a full frontal view of the little girl’s pert young tits, and the light fuzz that topped her almost hairless little snatch. This unexpected delight, caused the boy to suck in his breath with a slight gasp.
Julie heard her brother’s intake of breath, but carefully acted as if she hadn’t noticed. Continuing her motion, the girl spread her legs, and lay on her back, giving the boy a complete view of her open little cunt, now starting to drool cream at the thought of turning on her little brother. Ever since the little girl had started having periods, she had been dreaming about putting on a show for a man, and possibly even getting fucked.
Her mother had explained to both the children when they were younger, about how babies were made, so Julie knew what happened. It was scary, thinking of having a baby, even though it was also exciting. So Julie mainly dreamed, not daring to actually try anything.
Now, knowing her little brother was sneaking peeks at her naked body, turned the little girl on. She had never thought of her little brother before as a possible sexual partner or boyfriend, but the kid shared her good looks, was bright and friendly, and in general, was all that a girl could ask for.
Julie decided to try and “make-out” with her brother. They couldn’t actually fuck, as she didn’t want to get pregnant, but there were lots of things two horny kids could do without actually fucking. Julie thought it over, all the time carefully turning her body to give her little brother fresher and even more tantalizing glimpses of different parts of her developing young body.
How could she get the little boy into her room, with both of them naked, without seeming like a slut? He was obviously interested, and from the shiny head of the oversized-for-a-12-year-old penis that was peeking out of the top of the little boy’s shorts, well equipped for the job.
A slight ache in her neck, as she tried to keep the boy in view, in the mirror, gave Julie the idea she had been searching for.
“OW!” said Julie. “Aughh! Oh that Hurts!” The little girl twisted as if in pain, and lay face-down on the bed, trying to reach her back as if she were in agony.
Mike had been enjoying the show, when he saw his older sister seemingly strain her back, and collapse onto the bed. Worry about his sister being hurt, overcame his fear of being caught peeping. “What’s the matter, Julie” he worriedly inquired.
“My back. It’s killing me. I think I got a cramp.” Julie hammed it up for all she was worth.
“Shall I go get Mom?”
Their mother was the last person Julie wanted to see at the door right now, maybe her handsome father but ….Julie shut that thought off with a snap. “No. It’ll relax in a minute,” she explained. “Maybe you could help by rubbing my back.” Julie carried on with her plan.
Tentatively, Mike approached his beautifully naked big sister. He was so excited, at the thought of actually touching the girl’s naked skin, he didn’t notice the her movements, that belied her “cramp.” “You mean like this?” he said, starting to massage the little girl’s shoulders.
“Yes, but farther down” directed Julie.
Dutifully, Mike started massaging “farther down,” until he was rubbing the middle of the girl’s back. “How’s that?” he inquired.
“Fine, but harder,” requested his sister.
Mike was already rubbing as hard as he could, the little girl kept being pushed away, when he tried to do it harder. He explained this to his sister.
“Why don’t you get on top of me, and do it.” Julie almost snickered, as she realized how well her plan was working.
“Uh Julie,” warned Mike, “you’re naked, and I. . .” How could he tell his innocent sister that he was sporting a hard-on for her.
“That’s OK. I don’t mind. Why don’t you take your shorts off too, if that’s what’s bothering you?” Julie was so proud of herself for thinking up that line, she almost burst out laughing.
“But Julie, I’ve got. . . ” He couldn’t say it.
“So you’ve got a hard-on. Big deal! Just don’t try to stick it in me. OK?” Julie hid her face in the pillow, so her little brother couldn’t see her expression and spoil everything.
Mike couldn’t believe his luck. His big sister didn’t mind. Now he could get on top of her, and feel her body all over, under the pretense of giving her a back-rub. It was almost too good to be true. Hurriedly slipping out of his shorts, Mike climbed on top of his sister, and started to rub her back.
Julie was pleasantly surprised. The little boy was good! He pressed into the small of her back with his fingers, and began giving her a massage that threatened to put the little girl to sleep. After working a while on her back, the boy began running his hands up and down her sides, and then he began rubbing her shoulders like an expert masseuse.
Presently, Mike had somewhat of a “big” problem. His hard penis was banging against his sister’s cute little butt, and leaking clear slippery fluid down into the crack of the little girl’s ass.
Julie enjoyed the feel of her brother’s penis sliding against her rounded little ass.
“Julie. My thing is getting in the way,” said Mike. “Can I put it down between your legs for a minute?” Mike held his breath, waiting for his sister to answer.
“Well, OK. Just for a minute. Just don’t get any of your cum in me,” agreed Julie.
Mike continued rubbing her back, while he started sliding his penis down between his sister’s legs. The boy kept on sliding his dick past the clenched lips of his sister’s vagina. Each time the tip of the boy’s penis slipped by the entrance to her vagina, he would push the head in a little, and let a bubble of slippery liquid lubricate the girl’s little hole.
Julie felt her brother pressing the head of his prick into her now slippery hole. “Stop it!” she said. “You almost went inside me that time.”
Mike resumed sliding his penis past the lips of his sister’s vagina. “Don’t you like it?” he inquired.
“Yes, but we shouldn’t,” she replied. Still, Julie began working her hips in time with the sliding of her little brother’s prick. She enjoyed the slip-sliding feel of his penis rubbing against her pussy lips.
After waiting a bit, Mike once again pushed the head of his engorged penis against the opening to his big sister’s vagina.
This time, Julie didn’t stop him, as Mike let several big drops of pre-cum lubricate his sister’s hole.
“You aren’t cumming inside me, are you?” inquired Julie, worriedly.
“Just making it easier for my dick to slide, while I rub your back,” reassured Mike.
The next time that Mike felt the tip of his penis reach his sister’s hole, he pushed in a little harder. There was a popping sensation, and the little boy felt a ring of muscles slip over the head of his prick.
“You little bastard. You slipped your cock inside me, didn’t you.” There was no heat in the little girl’s accusation, and she didn’t pull away.
“I’ve just got the tip in,” lied Mike.
“It feels like more than just the tip,” grumbled Julie, but she said no more, as she relaxed into her brother’s continuing back-rub.
Mike continued to rub his sister’s back. Only now, he was sliding the tip of his cock in and out of the lips of his big sister’s hole, enjoying the sensations, each time the muscles of the girl’s vagina snapped around the head of his prick.
Julie knew what her brother was doing, but was enjoying herself too much to object. After a short while, she started to push back at her brother. More and more of the little boy’s penis slid into his sister’s belly, until the head of the boy’s prick rested against his big sister’s unbroken hymen.
“You’d better not knock me up, you little bastard,” said Julie, pushing back at her little brother.
Mike pushed his hard penis in and out of his big sister, until he knew he was close to cumming. “Stop Julie!” he said. “I’m almost ready to cum.”
“Don’t cum in me!” the girl cried. “I don’t want to get pregnant!”
“Just wait,” he continued. “No don’t pull off. Just hold on. If you pull off, I might cum inside you before you get all the way off. Just hold still. Don’t move!” Mike gritted his teeth, and fought down the sensations that almost had him squirting his seed all over the inside of his own sister’s tight little vagina. Shortly, the boy felt a slight releasing sensation in his cock. He didn’t know if what he released inside his sister was cum, or just more lubricating fluid, but his prick was still hard, and the boy no longer felt like he was going to ejaculate sticky white baby-juice all over the inside of his big sister’s tight little belly.
“Ooooh. OK,” he said. “We can continue now.” With this, Mike started fucking his sister, sliding his cock all the way up to her unbroken cherry, and all the way back out. Back and forth. Back and forth. Mike was really fucking his sister now.
After a while, it got to be too much for Julie. “Stop,” she said.
“Huh?” Mike asked.
“I want to turn over, so that we can do it right,” she explained.
“Are you sure?” Mike wanted to know.
“Uhuh. If your gonna fuck me, let’s do it right.” With this, the little girl turned over, and placed her brother’s hard prick against the opening to her vagina. “Now push,” she commanded.
Mike pushed, and his penis slid all the way up inside his sister’s belly with a rush. There was a snapping sensation, and Julie felt her hymen break. Then the little girl started to climax, knowing that she had her own handsome little brother’s big baby-making cock stuck all the way up inside her tight little belly, where it belonged.
“Horny little bastard. You wanted to fuck me. Well fuck away!” she cried. “You’d better not cum inside me though. I don’t want to get pregnant.”
Mike felt like he was in heaven. He slipped his cock in and out of his sister’s belly, enjoying the feeling of her vagina squeezing on his engorged penis.
Julie loved it too. The girl hadn’t realized how good it would feel to be fucked. Soon, she found herself in the throes of a another even mightier climax. “Cum. Cum. Cum. I’m going to cum!” she panted.
“Julie don’t,” warned Mike. ” You’re going to make me cum inside you.”
Julie was too far gone to stop. The climaxing young girl wrapped her arms and legs around her brother in a death-grip, and worked even harder. “Unh. Unh. Do it,” she encouraged, not letting him go. “Squirt your cum in me. Knock me up.” Julie couldn’t believe the words she heard coming out of her own mouth.
Mike couldn’t help himself. The boy began ejaculating big greasy ropes of thick white baby-making sperm right up inside his own sister’s tightly squeezing little belly. Rope after thick sticky rope of incestuous sperm squirted into the spasming belly of the little 13 year old girl, until both siblings were panting with exhaustion, and Mike had emptied his balls into his sexy big sister’s receptive young womb.
After that they wanted to try something else. Julie told him to close his eyes and lay down on his back. He did it and closed his eyes. Julie positioned her mouth over his cum and cunt juice covered cock she then started sucking it. Mike opened his eyes, very surprised as he was he didn’t tell her to stop. Mike asked, “Why are you doing this?”
“I just wanted to taste it and I saw Mom and dad doing it once and they looked like they were enjoying it!” replied Julie.
“Well it feels great! I think I’m about to cum pretty soon.” said Mike. Knowing this Julie began sucking even harder. Taking the young boy’s cock deep into her mouth and licking every inch. Then Mike started tensing up, and a second later Julie’s mouth was full of cum. She swallowed it eagerly. Then told Mike about the wonderful taste.
The children, tired from their new experience, lay there snuggled together, and in a dreamy state they drifted of to sleep. And thats exactly how there parents found them two hours later. Mike with his penis laying almost on top of naked little Julie!!
