Dominating Sister

Big sis is the boss and Donny loves it that way

Erotic Fiction

Part-1

Our mother had gone off for the weekend, leaving my sister, Mandy, and me alone. But we weren't alone long, because she invited one of her boyfriends, Chad, to come over as soon as he got off work.

I was in my bedroom on my computer when I heard Mandy let him in and take him right to her bedroom, leaving her door open. They got right into it and didn't even try to be quiet. I heard her tell him to take her clothes off and suck her tits. After some moaning on her part, he told her to take out his cock and suck it. Moans, groans, and filthy talk escalated from there, and soon I heard her headboard knocking against our adjoining wall. Then it went quiet, and I knew what was coming next.

"Hey, Donny, come in here!" my sister called out.

I stepped into the doorway and saw them lying together, naked. His dick was soft and lying across his leg. Her legs were parted and her pussy was wet and not just with her own juices, but his spunk, as well.

"Come over here and clean us up," she told me.

I walked across the room and the smell of fresh sex grew stronger as I approached them. My dick had already been stiff in my pants from listening to them fucking, her command to come into her bedroom stiffened it even more, and now the sight and smell, plus my anticipation of what was coming had it drooling against my leg.

"Who first?" I asked in the meek, resigned tone that my sister was expecting.

"Chad," she said. "See if you can get his cock hard again while you're sucking our juices off it. Maybe, if you ask nice, he'll fuck your tight little ass while you clean up my pussy."

***

I should probably give you some background here. My sister is a year older than me, and even from an early age, she was bossy and domineering. I'm not sure if I let her boss me around because I was

born

submissive or if I

became

submissive because I grew up

being

bossed around. Either way, here I am in my mid-twenties and a willing sub to my sister.

Another thing you probably need to know is that we're both hypersexual. From puberty onward, neither of us could get enough sexual pleasure. We each started out masturbating on our own, of course, but then one day she caught me jerking off in the basement looking at our dad's girlie magazines. When I saw her, I tried to pull up my pants and hide my pecker, but it was way too late.

"Keep whacking off," she told me. "I've never seen a guy's boner squirt before!"

"No way!" I told her and got my pants up.

"If you don't, I'll tell Mom and Dad what you were doing," she threatened.

"You got no proof!" I said defiantly as I zipped up.

She thought for a moment and then said, "I'll let you watch me play with my pussy."

Well,

that

got my attention! A real live pussy? Holy shit! "We do it together?" I said. "Right here? Right now?"

"Mom won't be home for half an hour," she said as she unzipped her jeans.

"I ain't gonna last

that

long!" I said with a chuckle as I unzipped, too. As I pushed my pants back down to my ankles and my boner sprung straight out, she said, "Take off your shirt, too. I want to see you naked when you beat off."

I wouldn't understand exhibitionism until some time later, but that she wanted to watch me as I jerked off --naked--added a hot spark to the arousal I was already feeling as I anticipated seeing my first live pussy.

As I unbuttoned my shirt, I took a leap, and said, "Can I... can I see your boobs, too?"

"Say please," she said with a smirk.

"Oh, please, please!

Pretty

please!" I begged.

She laughed, and pulled her tank top off over her head as she said, "Well, since you asked so nicely."

At the time, her tits were still small enough that she rarely wore a bra at home, and I was suddenly staring at the young tits that I had been trying desperately for months to catch just a

glimpse

of.

They were pale white against her lightly tanned body, were the size and shape of the martini glasses that our parents used, and had lovely pink puffy nipples. I could have stood there and jerked off just staring at those gorgeous tits.

I let my eyes scan down her now-naked body, over her flat belly, and reattach their focus on the triangle of curly hair that sat in the middle of her bikini tan-line. My aching boner twitched all by itself, oozing a drop of pre-cum, and I wasn't even looking at her pussy-lips, yet!

She was staring at my dick and obviously noticed it jump and drool, because she said, "Well,

somebody

likes what they see."

"Oh, fuck, yeah!" I said. "We both do!"

She turned around and walked the few steps to our dad's workbench. My eyes were glued to her cute round, lily-white ass. She took a rag or towel or something and wiped a spot on the bench, causing her ass to wiggle back and forth as she wiped, and my boner drooled again. She turned back around, hopped up on the bench, and spread her legs.

"How about this?" she said with a teasing grin. "Do the two of you like my pretty pussy?"

"Oh, fuck, sis!" I said as I stepped closer with my fist now wrapped tightly around my cock. I pulled on it a couple of times to get even more dick-juice to drool out, I caught it and wiped it down the length of my ready-to-burst boner.

I should point out here that this was in the days when you still had to pay for Internet porn, and the

men's-magazines

that my dad had--like

Playboy

--were still only showing pubic hair, so this was the first time I had ever seen what I had only been able to imagine while I masturbated: a flesh and blood pussy!

I wouldn't know for a long time how varied pussies could be, but hers was a clamshell, so when she reached down and pulled her pussy-lips apart, exposing the wet, obviously-soft, pink folds of her

cunt

, my knees nearly buckled.

She slipped her middle finger into those wet folds, and as she began sliding it slowly in and out, she said, "Let's cum at the same time."

"You better hurry up, then!" I said. "Because my balls are ready to frigging burst!"

"Go slow 'til I catch up!" she commanded and began jabbing her finger in her cunt faster.

The sight of my sister's naked--open!--pussy was nearly enough to give me a hands-free orgasm all by itself. Then, watching her finger-fuck her gash, hearing the wet squishing sounds it was generating, and then

smelling

her pussy made me have to strangle my cock around its root to keep it from blowing my pent-up load while she was

catching up

.

Apparently, this whole thing was damned near as arousing for her as it was for me because her hand was quickly flying as she slapped her pussy harder, faster, noisier, and smellier!"

"Now! Now!" she called out. "Jerk it off! Make it cum! My pussy's ready to squirt!"

I began hammering my cock faster and harder than I think I ever had in my life. We were each staring intently at one another's flying hands when she let out this high-pitched whine and her pussy gushed all over her hand like she was peeing.

"Fuck!" I growled as my balls tightened and my pent-up cum started up through my cock. Only there was a problem. Exposing myself to my sister, finally seeing her naked tits then her naked pussy, then watching her spread her cunt-lips and jab her finger up her cunt, made me forget all about the paper towels I was going to use to catch my cum while I was jerking off looking at mere

pictures

of naked women.

The thick rope of hot cum ripped up through my cock with that glorious first-shot burn, flew through the air, and landed on Mandy's leg, hitting her below the knee and running down her calf.

"Oh, fuck, sis! Sorry, sorry!" I blurted and tried to hold back the rest of my jism while I looked for a rag or something.

She would tell me later that when she fantasized about watching me jerk off it had never occurred to her to let me do it

on

her. But when she saw that thick, white squirt erupt from my pee-hole and then felt it smack her leg and felt its heat it sent a spike straight to her pussy that was like a splash of gasoline on the fire of her orgasm.

She stuck her leg out and I thought she was trying to kick me in the balls for squirting on her, but she told me, "Squirt on my foot! Jerk it off on my foot!"

Having momentarily stymied my orgasm, the second squirt I pumped from my cock felt almost as good as that first one and was damned near as thick and long. It landed on her foot and ran down between her toes.

"Holy shit!" she cried out and lifted her foot so my cock-head was squishing through my jism as I continued to jerk off while staring at her hand slapping her sopping wet pussy as she drove her finger over and over into her cunt-hole.

I didn't want it to ever end, but eventually, I couldn't coax any more sperm from my balls, and as I stepped back on wobbly legs, my sister--who had slowed her pussy-beating but still had her finger up her cunt--surprised me again by telling me, "Lick it off! Lick your messy cum off my foot and off my leg!"

I often tasted my own cum when I jerked off, but being

told

to do it by my bossy sister while she had her finger up her cunt was not something I could ever even have imagined. The combination of her assertive tone, our mutual nakedness, the smell of raw sex in the air, and my inexhaustible supply of young male hormones made me bend over and pull a big slurp of my jism into my mouth without the slightest hesitation.

My dick--which had softened only slightly after my orgasm--sprang right back to full

cock

status as I chased my splooge around her foot and then licked the first gooey rope from her calf. Then it was

my

turn to surprise

her

.

I stood up and moved between her still-spread legs, took her face between my hands, and pressed my cum-filled mouth against hers. She resisted for just a second, more out of surprise than revulsion, and then parted her lips and we went into a steaming, lip-sucking, tongue-dancing, cum-swapping kiss that seemed to go on forever.

It was the first time that she and I had ever kissed, but like all of the other firsts that happened that afternoon, it was not going to be the last!

***

So, where was I? Oh, yes; Chad and his messy, wilted pecker.

He rolled onto his back on the bed and spread his legs so I could crawl between them on my knees. Before I bent down, Mandy--always in command--told me, "Take your dick out, little brother. Your balls, too. I like to watch how your boner drools when you're cleaning up one of my boyfriends' cocks."

Another note of explanation: Boyfriend is probably not the right word to use for Chad.

Fuck-friend

would be much more accurate, and he was one of many that Mandy has. She had me service many of them, and I have to say that Chad was one of my favorites. But more on that later.

Dutifully, I unzipped my fly and maneuvered my boner and my balls out into view. Then I bent down and using just my lips and tongue pulled Chad's deflated dick into my mouth. I love the feel of a soft, squishy penis in my mouth, especially when it's soaked with the combined tastes of boy and girl cum. With my lips pushed right into his wiry pubic hair, my cheeks bulged with his curled-up dick. But it didn't stay curled for long.

As it re-inflated and began to straighten out, I pulled back and began bobbing up and down on what was quickly becoming an erection once again. I stopped bobbing with just his knob in my mouth and my lips locked around his fire-helmet-ridge, and swirled my tongue all over it. I pressed against its squishiness, I tongue-stroked the wide cleft underneath, and I wiggled the tip of my tongue into his pee-hole. His fat, mushroom cock-head is one of the things I like about Chad.

Suddenly, I felt my sister's hand on the back of my head and I knew just what was coming. And I was looking forward to it... so was Chad.

She pushed hard and drove my head down until my lips were pressed into his pubes again, but this time his limp penis didn't fill my cheeks, his stiff cock filled my throat.

"Oh, fuck, yeah!" Chad groaned and pulled Mandy over to give her a big kiss. "Shit, baby!" he said when their lips parted, "You've trained him to swallow cock almost as good as you do!"

"He's always been a very willing trainee," she replied. She closed her fist, grabbing a handful of my hair, and pulled my head up, extracting his cock from my throat and all the way out of my mouth. I knelt there with my mouth open catching my breath with a web of throat-slime connecting my lips to his glistening knob. My own cock-head was wet, too, but with my own pre-cum. It was amazing how much being

forced

to do something that I loved anyway made it so much more arousing. I was--and am!--a sub through and through.

"Stand up and take your clothes off!" she told me. When I had stripped and was standing there with my raging hard-on sticking straight out, she told me, "Lie down on the bed! On your back with your head over the edge. Chad's going to need some lube if he's going to fuck you up the ass, and there's nothing better than thick, slippery, organic throat-slime."

A few moments later, Chad was standing beside the bed, I was lying on it, and I was looking, upside-down, at his cock and balls. Mandy leaned down close to my face, and taunted, "Open up, little brother. Chad has a present for you!"

He stepped forward and put his cock-head into my mouth, I clamped my lips around it, and he began fucking my mouth while I pushed my tongue against his plunging knob. The combined taste of Mandy's pussy and his spunk was gone, but I was clearly tasting his pre-cum.

From the very first time that Mandy "made" me give one of her fuck-friends a blowjob (I had actually begged her to set it up) I was hooked on cock. I love everything about it: The feel of the engorged flesh between my lips; its heat against my cheeks when I suck; the squishy knob against my tongue as I swirl it around; and oh! the taste! Or, I should say

tastes

, plural.

The first taste I had just enjoyed that first time was a

clean-up

, as the guy had just gotten done fucking my sister. I knew what her pussy tasted like, of course, but it was so different sucking it off a cock mixed with the dregs of his cum. Then, the first time I got to taste cum fresh from the cock, she had

forced

me to kneel in front of another of her fuck-friends while he beat off into my mouth. The taste of his jism and the feel of his hot splooge hitting my tongue caused my own rock-hard dick to shoot a hands-free orgasm that landed on the guy's leg and foot. In a replay from that first time with Mandy, she made me clean him up with my mouth.

Sorry if I keep wandering from my story; my mind is like that when it comes to sex. But maybe this is a good time to tell you why I like Chad. Aside from having a great cock--which is probably seven inches long, an inch and a quarter thick, and capped by that even fatter mushroom cock-head--he's a respectful and open-minded fuck-friend.

He

even gave

me

a blowjob one time just to see what he might be missing out on. He didn't let me cum in his mouth (few guys do the first time) and later said that it was okay but that he wouldn't give up pussy over it. (Shit! Neither would I, but I love being able to swing from both sides of the plate when either opportunity presents itself!) He also gets the relationship that Mandy and I have, which is not easy for many guys to comprehend. He understands that we truly love each other and that the sub/dom thing is more role-playing between us than actual one-sided domination.

Anyway, back to Chad's stiff cock in my mouth...

He stood there fucking my mouth as I sucked and worked his plunging boner with my tongue. (If I have to say so myself, I give a good mouth-fuck!) After a dozen or more fucks, Mandy put her hand on my throat, and told him, "All the way, this time! I want to feel your fat cock bulge his throat!"

He pushed forward until his big balls were squashed against my inverted face, and Mandy said gleefully, "Oh, yeah!

That's

going to pull out some slime!" as she caressed the bulge in my throat almost as if jerking it off.

"Again!" she told him. "A few more times." To me, she said, "Suck your slime off his dick while he pulls it out and hold it in your mouth, little brother. Your tight little asshole is going to need all the lube it can get to take his fat cock!"

He pulled out for a moment, let me catch my breath, and then pushed his boner back down my throat. He repeated that two more times. All the while, my own boner was standing straight up and drooling pre-cum down its length. If I had grabbed it and pumped just three or four times I'm sure I could have shot a geyser of cum into the air. But dutiful sub that I am, I knew I needed to wait until my sister told me I could jerk off. Which was actually fine with me anyway, because the load that was building in my balls just kept getting bigger and bigger.

When Chad extracted his dick from my mouth the next time, Mandy commanded me, "Roll over and get up on your knees! And don't swallow that slime!" A few moments later, I was on my knees and elbows, and Chad was crawling up between my legs. Mandy put her hand in front of my face, and told me, "Spit it out!"

I drooled the mixture of collected slime and spit into her palm and then she turned and wiped some of it over Chad's cock-head and down his shaft. But she kept a good glob of the goo for my ass.

I felt her fingers press into my ass-crack and then swirl around my sphincter as she spread the all-natural lube. She could have pushed her finger--or fingers--up my ass to loosen me up, but she knew that I liked the feel of the tip-stretch as much as she liked watching my pucker swallow a fat knob.

My first anal experience--aside from Mandy's fingers--was with a fuck-friend of hers that I ended up calling

pencil-dick Pete

. His pecker was probably seven inches long, but barely as big around as my thumb. As it turned out, that was a great size to open up my asshole to the glories of anal sex.

Sorry. Back to Chad and my asshole.

So, I felt Chad's knob press against my pucker at the same time he took hold of my hips. Mandy was on her knees beside me with her face near my ass, and she was spreading my ass-cheeks with her hands. I felt four hands on me, so I knew Chad was lining up on my rosebud hands-free.

Little by little the pressure on my sphincter increased and I forced it to stay relaxed against the foreign invasion. As my pucker stretched to accommodate Chad's cock-head, the feeling went from simple pressure to slight discomfort, to mild pain, to searing burn, and I loved every incremental step of it! Finally, his knob popped inside me and my sphincter snapped back a bit, gripping his cock-neck and locking us together.

"Oh, fuck!" I groaned into the pillow under my face.

"Does little brother like getting his asshole stuffed with fat cock?" Mandy taunted me.

"Oh, fuck yes!" I answered. "Can he... can he do that again? Please?" I asked in meek, sub-fashion.

"Well, since you asked nicely," Mandy replied and eased him back, extracting his knob from my ass as slowly as it had gone in.

I let out another "Oh, fuck!" as the sphincter-burn disappeared, but then, "Oh, yes!" as she pulled him forward and his cock-head popped inside me again, a little faster, this time.

I wasn't counting how many times Mandy had him tip-fuck my ever-loosening asshole, and I was torn between wanting him to continue that in-out, burn-relax sequence, and wanting to feel his fat cock stuffed into my guts and poking my prostate. The paradoxical pain/pleasure of having my asshole stretched was a great part of anal sex, but the kicker was getting my prostate rubbed by a stiff cock.
