***

I didn't expect I'd be having threeway sex with my mother and sister, after seeing my dad cheating on my mom with some rando.

OK, that's an overly specific denial. Sooo... I didn't expect, or plan, to fuck my mother. Didn't expect to fuck my sister, either. And really, REALLY didn't expect to wind up in bed in a puppy pile with them at my college apartment.

I can just hear my sister, Ciara, chime in that I don't anticipate stuff 'cause I'm super bad at planning. And thinking in general.

I put up with her frequent insolence because I kinda like my sexy little bratty sis. As you might have surmised by that 'Me And Her Fucking' thing.

Anyhow, I was sitting between mom and sis, on the couch in my apartment near my college in Dallas. Or as Ciara liked to call it, 'our apartment', since she kinda moved in with me after we started fucking on her eighteenth birthday. It seemed unwise to disabuse her of the notion.

We were all drinking berry daiquiris. This was several hours after the 'Need to Bleach My Eyeballs to Block Out the Memory' incident where we all caught my dad fucking yet another skinny skanky blond at our house in Austin.

My mom, Aleja, was sipping at her second daiquiri, apparently trying to forget about the de facto end of her marriage. She bit her lower lip, looking at me then Ciara, like she had something to get off her voluptuous chest.

"Mom," Ciara said.

"Hmm?"

"Just say it. I can almost hear the squeaking of the wheels as you hamster-wheel about whatever the fuck's on your mind."

"Umm... would it be OK if I crashed on your couch for a few nights until I found an apartment here? Don't want to be in the same city as Cody, knowing he'll almost certainly be fucking a plethora of skanks now that he's totally screwed the pooch, marriage-wise."

"Of course you can. Stay as long as you like."

"I don't want to interfere with the... relationship... you two have."

"I think we're close to Peak Surreal, mom. What's a teeny bit more?"

"Seriously. Maybe it's the daiquiris talking, but... I think you and Lucus have the same chemistry as your dad and I had. You even look like younger and better-looking versions of him and me. I get the attraction. I..."

The silence lingered.

Ciara said, "Just spit it out."

"Phrasing?" I said.

"Hush, pervert. The adults are talking."

I stuck my tongue out at her. "Pppthhbbb!"

Mom said, "If you two are quite done with that articulate repartee..."

"Yeesss?" Ciara said.

"What I was getting at was... I think you two make a great couple. Taboos be damned." She gave me a concerned look. "Don't you go fucking around on her and break her heart. If that's all this is to you, a bit of fun -- better say it now. Cause she's a beautiful person who's inexplicably been mistreated by men because of her luscious curves. God knows I dealt with enough of that bullshit myself."

Wow. She actually thinks I want to cheat on Ciara? After watching my dad, just hours ago, torch the remnants of his marriage by humping yet another slut? "First you told me, date other women. Now you say the complete opposite?"

"Answer the damn question," Ciara said. " Do. You. Want. To. Date. Other. Women?"

"I don't want other women. I love YOU!" I blurted out, not thinking.

Hunh. Maybe I mixed those daiquiris a bit too strong.

It got super silent and awkward.

Ciara looked like she was trying not to cry. "Awwww. I wuv you too," she finally said in this high-pitched little girl's voice.

I raised my eyebrows. Was that, like, understated sarcasm? Or deflection? Or... does she --

"I love you, too," she said, softly, back to her usual voice, a sultry sexy lioness' purr, if said lioness had a Southern drawl. "You have no fucking idea how much I've loved you, ever since I was a kid."

Wow. I'm really bad at mindreading. How'd I miss that?

Mom glanced at her, then stared at me. Raised her eyebrows expectantly, like my mindreading powers had suddenly gotten way better in the past five seconds.

The silence lingered. I turned my palms upward, and silently mouthed 'What?' at Aleja.

Mom pushed me against Ciara. "Hug her already, you idiot. Kiss her."

I gently wrapped my arms around my sister's waist. Kissed her.

Mmmm. Feels so good. God she smells wonderful.

My Wild Penis (as I've affectionately nicknamed that body part, since it ignores social conventions or appropriate demeanor), never one to read the room well, started rising to the occasion.

Mom quietly cleared her throat. "Umm, a private word, Lucus?"

I tried to break the hug, but Ciara was hanging on tight, like she didn't want the moment to end. So I put my hand on her chest -- fine, technically her right breast, and a wonderfully squishy one it is (for some weird reason, that thought about her breast popped into my head with an Irish lilt) -- and gently broke the hug. I scooted over to the other side of the couch by Aleja.

She leaned over and whispered in my ear, "I think you should try this, 'cause you know Ciara's a bit insecure about her figure, even though she's a beautiful and sexy woman: Kiss every part of her body you find sexy -- but don't fucking lie, skip over anything you're not as enamored with -- starting with her hair and down to her feet."

"Might get distracted midway down," I whispered back.

"Keep it moving, Bucky, all the way to her feet."

" 'K."

Mom nudged-shoved me back toward her.

"Hey, Ciara..."

She raised her eyebrows. "Hmmm?" She tilted her head up and parted her lips, inviting another kiss.

I kissed her curly black hair instead, feeling it tickle my lips, then forayed inward, pressing my lips against waves of heat from the top of her head. Like her massively smart brain was working overtime here, overheating as she thunk smart thoughts. Or deviously plotted her seduction of me, even though she had me at, 'I've loved you, ever since I was a kid.'

She's a hard one to read sometimes (My internal Irish accent resurfaced, randomly.) "I love your gorgeous hair. Like, lots of women must suffer Hair Envy."

"Thank you, kind sir," she said in a squeaky little girls voice. Deflection. Again.

I kissed her forehead. "And, despite your frequent insolence to your long-suffering brother, I love that wicked smart brain under all that lovely hair."

She wrapped her arms around my neck and gazed up at me with this adoring look. "Go on..."

I kissed one of her eyelids, then the other, her eyes closing just in time. "Ohhh, and those perfectly symmetrical beautiful brown eyes of yours... I could look into them all day long."

I kissed her adorable wide but little nose. "Such a cute nose."

Then her lips, softly. "And those beautiful large pillowy lips you can just sink into all day long... mmmm."

"Keep that up, sir," she whispered, "and I might kinda sorta start liking you."

I couldn't resist making the joke, risks be damned -- the words just heedlessly flew outta my mouth: "Specially when I sink my cock into thos--"

Mom made this warning throat clearing noise. Ciara gave me a symbolic warning slap to the cheek, then a bunch of semi-apologetic quick kisses.

"Ow," I said, though she hadn't hurt me at all.

"Don't be a baby. Moving briskly along..." my sister said.

I figured she expected me to go next to her breasts. But, rule number four of seduction: keep 'em off balance. So: a flurry of light kisses on her cheeks, the indent on her chin, her earlobes... "You have a gorgeous face. So beautiful."

And so on... I kissed damn near everything on her body -- shoulders, neck, arms, hands, breasts and nipples. Lavished extra attention on her belly, 'cause I knew my little sister was weird about that, and needed reassuring that I found every fucking part of her body hot and sexy.

Rule number four again: detoured around her pussy, kinda nibbling around it on her inner thighs, even though her wet cunt smelled sooo goood.

I wound up sitting on the floor between her parted thighs, noticing signs of her arousal -- hard nipples, wide open pupils, her already large breasts swollen from extra blood flow, a musky perfume wafting off her wet pubic hair. I gave Ciara leisurely kisses on her pale coral pink painted toenails, which looked surprisingly sexy next to the surrounding dark skin. Maybe I was surprised by the novelty because my gaze rarely gets that far south on a woman's body, what with all the distracting curves along the way? Dunno.

She had this curious look on her face, both aroused and insecure. The detour of her pussy? Yeah, had to be bugging her.

And then I cashed in on the delayed gratification gambit -- put my tongue on the inside of her left kneecap and quickly gave one looong slow lick up her inner thigh, all the way to her tropically hot and soaking wet and oh so wonderfully musky aroused pussy, thinly covered by matching coral pink silk panties.

I buried my face in her delicious mound and yanked down her panties, mumbling into her curly dark and dank public hair, "This is the greatest pussy EVER" -- though it sounded more like,"Mmph'st da grtst puh-y 'VER," what with my tongue and lips exploring her soaking wet mound.

Ciara moaned and thrust her hips at me. She grabbed my head with both hands, forcing my tongue even deeper inside her slick tunnel. Opened her legs wider apart, inviting me inside her.

Even though my dick was rock hard by then, I wanted to keep tasting her and teasing her. I wanted to hear and feel her cum, so I licked and sucked and tongue-fucked her heavenly tasting and smelling pussy.

I heard some lustful animal noises coming from mom's general direction, so I took a sideways peek at her while continuing to bring Ciara to the brink of an orgasm.

She was staring at us, biting her lower lip then parting her sexy plump brown lips, an aroused look in her eyes. She caught my glance. "Should I... uh... give you two some privacy?"

Ciara said, "Stay and watch, mom. If you wa---aaaaah-nt!", a bit distracted by a couple of my fingers sliding deep inside her, finger-fucking her.

" 'K." Mom slid a hand into her shorts, rubbing her pussy while her other hand fumbled to unbutton her shirt and free her large brown breasts.

My tongue flicked rapidly on my sister's black umber colored clitoris while my fingers deep inside her did the same thing to her G-spot.

Ciara's orgasm went off like a firecracker, her hips bucking up at me while she came - loudly. Wave after wave of orgasms, a slutty unquenchable lust I had become acquainted with the night of her eighteenth birthday party, when she happily gave me her virginity, and then we fucked some more, every day since. Demanding I keep her orgasms rolling off her in waves, again and again, like an insatiable sex addict demanding her pusher -- me -- keep inventing ways to make her body create the delicious sea of endorphins and phermones and every other lovely chemical our bodies manufacture. Delightfully coercing us hapless mammals into procreating, heedless of the consequences in the electric storming moments of orgasm.

I glanced and noticed Aleja furiously rubbing her clit and an erect nipple, trying so hard to get off. But, her orgasm seemed to be inhibited by Ciara loudly and in close proximity receiving my cunnilingus and finger-fucking.

My little sister must have noticed that too, because she grabbed my hair and yanked me towards Aleja. "Lick. Her. Pussy. NOW!"

I resisted, whispering, "I'm not gonna cheat on you!"

She whispered back, "Not cheating. You've got your girlfriend's consent to have sex with mom. Anyone else on the planet, I'll dump your sorry ass."

"Mmmm. So you're my girlfriend?"

"On a probationary basis. Try not to fuck it up. Now... lick mom's cunt!"

"Sir, yes sir!" I whisper-barked, sarcastically imitating a private in boot camp obeying orders from an officer. Letting her know she ain't the boss of me.

She shut up all my insolent backtalk by yanking my hair, way harder than necessary, and shoving my face into mom's pussy.

Ohhh, she smells amazing too.

I started licking.

And Aleja, apparently pretty pent up from all her edging, held my head firmly in place with both hands and began cumming. Loudly. Over and over.

Holy fuck, I thought as she thrashed and moaned and bucked her hips into my tongue and lips, rubbing her pussy juices all over my face. So THAT'S where Aleja inherited her multi-orgasmi--

My little sister slid under my legs and, facing upwards, took my cockhead in her hot welcoming mouth, inviting me to facefuck her.

I cautiously slid just an inch or so of my shaft between her plump dark lips, not wanting to gag her.

She gripped my ass cheeks and shoved me inside her mouth, deepthroating me until I was balls deep inside her. Tears welled in her eyes -- from the discomfort? or emotions? -- but her face had this shiny adoring look, like she was happy to do anything to please me.

"You're the best girlfriend ever!," I said, though mom's pussy, still fucking into my face as she kept cumming over and over, made it sound more like, "Y'r um b'ss g-fuh uhv!"

I belatedly realized that ranking girlfriends while having sex with two of them simultaneously was a perilously suboptimal choice. Fortunately, either mom couldn't understand what I'd muttered, or was enjoying cumming like a string of firecrackers too much to take umbrage.

This threeway relationship with my sister and mom is gonna be tricky, I thought hazily as Ciara withdrew almost all the way from my mouth, then did magical things with her lips and tongue to my cockhead.

I'm gonna have to try thinking for a change. 'Stead of just saying whatever the fuck pops into my mi--

Ciara's tongue began flicking rapidly against the underside of my mushroom head, sending jolts of pleasure through my head, and thinking was suddenly not really a thing I could --

Fuuuuuuuck!

"Don't stop!" I said.

Which of course caused my sister to stop and withdraw her lips to say, a faux innocent look in her dancing lovely brown eyes, "Does this feel sorta good?"

I growled this deep animal noise and rolled my eyes up into my head, momentarily incapable of words, and gently pushed my hips down until my little head was enveloped again by her soft lips.

My mom resumed facefucking me with her pussy, rubbing her stiff little dark clit against my lips and making a lot of growly erotic noises.

She had apparently gotten over her sorrow over the breakup of her marriage, at least momentarily.

This not-quite-69 went on for what seemed like hours, though perhaps it was just ten minutes. Ciara was edging me by fondling my balls, and putting them in her mouth and humming, and lavishing attention to my purple-ish mushroom with her lips and tongue. She brought me to the precipice of orgasm over and over, only to pull off and make wry commentaries such as asking if I was still on the fence about fucking other, far less sexually talented women. So I would shove my cock back into her face to shut up her sassy impudence.

Meanwhile, I was doing similar things to Aleja's cunt and clit, sans the edging, instead provoking her into profane writhing as she rode waves of orgasms.

Eventually, my lips abraded by all the friction from her tightly curled pubic hair, I pulled away.

"What?" mom said, putting her hand on the back of my neck and pushing, trying to pull my face back into action.

"My lips are rubbed raw. Need a break from th -- mmmgggghhh", I said, growling in a strangled voice at the end, my thoughts short-circuited by my sister wickedly flicking her tongue on the underside of my little head.

She once again took her mouth off as I teetered on the brink. Grinned at my distress and then leaned her head back to look at mom upside-down and ask, "Perhaps we should take this to... OUR... bedroom?"

Hey! I thought. 'Our?' Shouldn't I be consul--

A look passed between my sister and mom. Aleja nodded, and Ciara slid out from under me. She and Aleja stood up.

I realized that a silent vote had just been taken about where this... group... relationship was headed. I reckoned the tally was about two billion 'ayes' to one 'excused from voting'.

I stood up and offered a hand to each of my two benevolent overlords -- I am nothing if not gracious in defeat. We walked towards a Cal king bed, with a white comforter with teeny little black hearts scattered in a random pattern.

One guess as to whether mom or I picked that design when she was helping me furnish my apartment.

We were still silently holding hands as we approached the bed, and exchanging loving -- almost shy -- glances. Like kissing, holding their hands was an oddly intimate thing, arguably more so than the recent oral gratification we had shared.

When we got to the bed, my mom and sister loaded up the Absolutely Requisite And So We're Not Gonna Argue About You Having One bedroom chair, with all the extraneous pillows that had mysteriously appeared one day when I was out of the apartment. It was as if the Pillow Fairies had shown up and decided that having only two functional pillows on a bed was just Not Done By The Quality. And promptly remedied that omission with a wretched excess of uncomfortable or downright unusable... but pretty... pillowage.

Then they took off their remaining clothing.

I'd been hoping to undress them -- slowly and sensually -- but it's poor objection management to encourage naked women you want to have sex with to cover up their bodies again, unless you have this CFNM (Clothed Female Nude Male) fetish.

So I took off my remaining clothing while the newly appointed Executive Committee in Charge of Thinkage, aka 'my sister and mom', whispered a bit. Then Ciara said, "What position?"

"Hunh?"

"Missionary... doggystyle... cowgirl... reverse cow--"

"Doggystyle."

They climbed up on the edge of the bed on their hands and knees, their hips and shoulders touching -- whispered something else -- then they both turned their heads to look at me.

Mom said, "So... who first?"

I suppose I should have been grateful that they had deigned to give me * some * decision-making authority, but my mind went on high alert to the danger of picking one over the other. I realized this was gonna be an ongoing peril.

Fuuuck, I thought.

I bought some time by stepping forward and literally kissing both their asses, lightly tickling them with kisses all over while kneading their sexy buns and thick thighs, first mom then Ciara. Then making them gasp by burying my face deep in the cleft of their buns, and giving each of their dark pussy lips a lingering kiss followed by a slow sensual lick, reveling in the sweet musky scent, and the soft dark flesh hugging my face.

Their asses were incredibly sexy and enticing. Mom's butt was the color of coffee mixed liberally with cream, much lighter than her skin exposed to the sun, reflecting her tropical Cuban heritage. Muscular and big, in the best possible sense of 'big', curvy and padded and oh so feminine. The kind of booty that rebuked the fashion model template of skinny pale boyish butts -- with the dirty little secret that a lot of models on magazine covers were in fact transsexual women whose bodies were literally impossible for non-trans women to attain.

My sister's buns were darker than mom's, closer to the color of coffee with just a dab of cream. Her figure had doubled down on mom's voluptuous curves, a magnificent huge ass that suggested that the Cuban part of her heritage included a lot of West African ancestors who had been captured by neighboring tribes and, as the euphemisms of the time might have put it, 'involuntarily relocated to jobs in the agricultural sector' to work the sugar and tobacco plantations.
