Back Seat Baby: A Cheeky Novelette

Chapter 3

Just those two little words coming from the man who usually can’t stand being in my presence for more than thirty seconds rocks me to my core, which is drenched with need. I clench my eyes shut and try to get my heart rate under control as Samir stretches and drags the wide waistband of my leggings over my ass and down my thighs to my shaky knees.

We simultaneously gasp when I drop my weight back onto his lap. Since I chose to wear a thong today so I wouldn’t have any visible panty lines that would show through my leggings, there’s nothing but the soft cloth of his gray sweatpants and whatever he’s wearing underneath them as a barrier between him and the bare skin of my ass.

“Oh god,” I cry out when he digs his thumbs into the crease of my thighs harder and works them inward toward my pussy until they meet the edges of the front of my thong before stopping for a beat. Just when I think he’s going to push them under the fabric, he slides his hands down my thighs to massage my quads, then back up again. He creates a circuit, repeating the pattern several times as I unintentionally writhe over his lap.

His legs have been a solid slab of muscle beneath me the entire drive, but when he moans my name and grips my hips to grind my ass back and forth forcefully over his lap, I feel it. A bulge. A huge, rock-hard bulge buried under his sweatpants and between my ass cheeks. The sound Samir makes when I wiggle side to side, nestling his bulge between my cheeks as I arch my back, has my blood rushing hot in my veins.

I could just combust when he rumbles in a gravelly voice, “Such a good girl for me.” He helps me rock over his bulge, both of us breathing hard as his bulge swells and lengthens. “Fuck, Becca. This ass…” His hands drift down to palm and squeeze my ass cheeks as I take over, rocking and bouncing my hips, helped along by the Tahoe speeding over a few potholes on the road.

I’m so wet now that my thong isn’t the only thing that’s soaked—his sweatpants are, too. He makes a low, throaty groan, and I yelp with surprise when he flattens a hand between my shoulder blades and shoves me forward so that I nearly smack into the cardboard wall.

There’s the sound of shuffling and rustling of clothes behind me, and I’d be embarrassed about my ass being practically right in my step-brother’s face if I weren’t so worked up. Samir reaches between my thighs, hooks his fingers in the fabric of my thong, and wrenches it to the side, exposing my wet, bare pussy. I know he can see everything while I’m in this position, and for some reason, that makes me even hotter. So hot that I can barely catch my breath, dizzied by adrenaline and excitement.

“Fuuuuuuck,” Samir grits out, and I jolt when he swipes his fingers through my slit twice and unexpectedly drives two of his fingers into my pussy.

I drop my forehead against the cardboard wall and brace my hands against it as I bite my bottom lip to keep from screaming when I tilt my hips and push my bottom back to take his fingers deeper inside me. I can’t believe it. Can’t believe how we got to this point where I. Am. Fucking. My. Step-brother’s. Fingers!

“Becca. Oh, fuck me, you’re so goddamned wet,” he says with wonderment, which makes my eyelashes flutter and pussy even slicker.

And oh god, the wet noises my cunt makes as he thrusts his fingers in and out is obscene. Obscene and so unbelievably erotic. I swivel my hips, my toes curling right along with his fingers, lighting up every nerve ending in my body when he drags his fingers over a particular spot inside me that has my mouth dropping open to moan his name.

Just when I think I’m about to cum, Samir yanks his fingers out, then jerks my ass back down on his lap. I want to protest, but he immediately cuts it off when he lifts his hips sharply, and bare skin meets bare skin.

I look down between my inner thighs and cry out, “Holy shit!” My core pulses with feral need and desirewhen I see he’s shoved his sweatpants halfway down his warm brown, muscular thighs with their smattering of dark hair.

I bite my bottom lip so hard that I almost draw blood because holy shit, holy shit, holy shit, this is really happening. We’re really both naked from our hips to our thighs, and I gasp brokenly when I’m impaled on an impossibly large, steely hard cock. I might not be a virgin, but I’ve never been this full before, and there’s still more to go.

“Oh fuck me, Becca, I knew you’d have a mind-blowing pussy.”

Oh god!I’ve never heard his voice as deep and primal as it is now, and my brain short-circuits, trying to commit it to memory for my spank bank in case I never hear it again.

There are still at least five more inches I have to take before my ass will meet Samir’s lap. His cock is longer and fatter than any dick or dildo I’ve played with, but it doesn’t matter. I’m so wet and turned on that when he pushes me up and pulls me back down at the same time as he thrusts his hips up to clap against my ass, my pussy stretches enough to accept all of him.

Samir slaps a hand over my mouth when I scream-moan his name. “Bad girl,” he growls and nips my earlobe when he forces my head back onto his shoulder.

I mewl as I try to rock my hips, and he bands an arm around my waist to hold me still. A whine works its way up my throat, and he presses his hand flat over my mouth, forcing me to breathe hard through my nose as I fight his hold so I can circle my hips and hopefully get him to thrust into me again. I need him to fuck me until I cum around the fattest, finest dick I’ve ever had.

Samir flexes his thighs, his shaft hot and pulsing inside me, but doesn’t make any other move. A tear of sexual frustration slips down my cheek and over his hand, and I try to peel it away from my mouth. He reaches under my T-shirt and thin sports bra to cup my breast and pinch my right nipple, making my belly cave in and flutter. I cry out into his palm, and he does it again.

“You’re being a very bad girl, Becca. If you want me to fuck you, then you need to shut up so Dad doesn’t hear you if he turns the music off. Can you do that for me?”

I nod as much as I can with my head pinned to his shoulder. My eyes roll in the back of my head when his fingers turn gentle on my nipple, circling the hardened bud with a soft caress, and my pussy contracts around him in response.

“If I remove my hand, will you be a good girl and be quiet for me?”

I hum my assent and clamp my bottom lip between my teeth. He slowly draws his hand away from my mouth, making sure I follow through on my promise to stay quiet, and then he’s fucking me with the same urgent need I feel.

His hands are back on my hips, gripping them hard while he holds me slightly above him as he pounds up into me, bottoming out each time, sending sharp zings of pleasure and pain up and down my spine. I swear I can feel the head of his cock behind my belly button with each powerful thrust.

Best. Dick. Ever.

I throw my hands up and back to claw at the headrest behind Samir’s head as my back bows, my stomach muscles going taut as he continues to thrust hard and fast. There’s a wet slap every time his hips clap against my ass, and that noise in and of itself is so filthy that I’m sure it will become another permanent fixture in my mental spank bank. I’ve never been fucked as hard or as good as I am now by my step-brother.

“Oh fuck, Becca. Fuck, fuck, fuck! Your pussy is so hot and tight,” he hisses as his dick swells impossibly larger, stretching me almost to the point of pain. He drops his voice and whispers with a dark, husky voice in my ear, “Such a good girl for me, being so quiet as you take your brother’s cock.”

“Jesus, Samir, don’t say shit like—” I bite my lip so hard that the taste of copper fills my mouth, and I cover my mouth with my own hand to keep from crying out when, without warning, my mind and body are blanketed by seemingly unending white-hot pleasure.

I don’t know how Samir can remain so quiet, even with his breathing as labored as it is, while I fight to keep my noises concealed as I fall apart with the most intense orgasm I’ve ever had. And he didn’t even touch my clit! I’ve never had an orgasm without any external stimulation, yet his long, stiff rod pistoning in and out of me gets the job done lightning quick.

“Becca…fuuuuuuck. Did you just cum? Your cunt is so tight, trying to milk my dick. So fucking sexy.”

I shiver at the awe in Samir’s voice as I ride the waves of ecstasy. Once they start to recede, I lose my grip on the headrest and sag against him with my back still arched uncomfortably because of my position as he starts slow-driving up into me, almost lazily.

What he said earlier comes back to me…“Such a good girl for me, being so quiet as you take your brother’s cock.” It’s dirty and sick, and I should be repulsed. Our parents are married to each other, and we share half-siblings, for crying out loud. We might not be blood-related, but we’ve been treated as if we were for the last four years, even if he hates me because of it. Yet his words alone have my cum-soaked pussy clamping my battered inner walls around him again.

I turn my head to the side and impulsively sink my teeth into Samir’s neck to cut off a scream when he slides a hand from my hip to my front and pinches and releases my clit between his index finger and thumb. Pinch and release, pinch and release. The pleasure from the external stimulation while he slowly thrusts into me with his oversized cock is so intense after cumming that it’s borderline painful.

I can’t keep them contained anymore, the moans that are forcing their way out of my mouth as he increases the pressure on my clit. And then I feel it—the surprisingly quick snap and release as my belly caves in with my second orgasm in less than ten minutes. I open my mouth to scream, no doubt having left a wicked bite mark on Samir’s neck that I don’t know how we’re going to hide from our parents. He captures my sob of pleasure with his mouth, twisting his head to the side to slant his plush lips over mine. The stubble on his chin scrapes deliciously against my skin, making my heart beat impossibly faster.

Samir. Is. Kissing. Me!

Why that shocks me more than the fact that he’s been fucking my brains out, I have no idea. He slips his tongue between my lips that I gladly part for him, and I slide a hand to the back of his head, weaving my fingers through his thick hair. All I can see, smell, taste, and feel is him.

Samir. Samir. Samir.

He owns every part of my body right now, and I can’t get enough of it. Of him. I’m practically mauling him as I deepen the kiss, tasting the faint cinnamon and mint lacing his tongue, letting him steal my air so I can’t scream and alert Dad to what we’re doing.

He breaks the kiss as his dick pulses and jerks. “Becca, Becca, fuck! I’m going to cum.”

I moan and clench around Samir’s firm shaft, but something…something I’m supposed to remember…breaks through the fog of lust. My blood runs cold, and my heart drops into my stomach when it finally hits me…

I lurch forward to sit up on my knees to lift off his cock. “Pull out. Pull out!”

Samir grips my hips to hold me still and pumps the fat head of his dick in and out of me shallowly. “Why?”

“I let my birth control lapse after I broke up with Matt,” I say with increasing panic.

His fingers flex. “Oh fuck, Becca, yes,” he growls and yanks me hard back down on his length, then loops a muscled arm around my stomach while he grips my throat, pressing my head back against his shoulder so I can’t move.

My mouth drops open, and my eyes roll back in my head as Samir braces his feet on the floor and savagely thrusts into me relentlessly from below. I’m right on the cusp of a third orgasm when my step-brother grips my jaw and forces me to tilt my head, then shoves his tongue in my mouth and cums inside me with a feral growl.

He slips his hand between my thighs to massage my overly sensitive clit aggressively and commands, “Cum with me, Becca. Be a good girl and fucking suck my cum deep inside you and say my name. Now!”

I cry out Samir’s name into his mouth as I fly over the peak of my blistering hot climax. I jerk and slap at his hand to get away from his unrelenting fingers on my clit, drawing out my orgasm for so long that I think I’m going to pass out from the sheer intensity of it. It’s only when I’m full-on crying from the strength and force of my release that Samir stops playing with my clit and pulls his hand away.

I sob and shake in Samir’s arms as I come down, my fingers and toes numb and twitching. I have no control over my body. Samir does.

“Good girl. Such a good girl for me,” he croons with an awed whisper as he kisses me so sweetly, tenderly caressing my belly. It’s a dizzying one-eighty from the dominance he exerted over my body just a few minutes ago.

My eyes drift closed as Samir circles my belly button, then splays his large, warm hand over my lower belly pooch. I can just make out his barely audible voice when he says, “My good girl. You’re mine now, Becca,” before I slip out of consciousness.
