You thought it was love. This guy wined and dined you then showed you the world. So when he proposes to you only three months into your relationship, you’re so smitten that you agree before he even finishes asking.
It must’ve been the honeymoon phase because a year later, you’re stuck at home while he galivants around the globe for his business. It’s not like you have a hard time, but you’re lonely, done begging for attention from a man who apparently just wanted someone to live in his empty house while he’s gone.
Then after months of stilted phone calls and cut short video chats, he drops by only to surprise you with a son from a previous marriage. Something you knew nothing about. After introducing Leon to you, he leaves him there—some flimsy excuse of letting you two get to know each other—and is off again once more.
Leon smiles at you as his dad leaves, “Sorry to drop in like this.”
Your frown smooths out as you take a deep breath, “Not your fault, sorry if I’m off kilter. He didn’t even tell me about you til now.”
You wince after saying the words out loud but Leon only laughs.
“It’s okay. I’ll stay out of your hair as much as possible.”
You wave your hand, “Don’t be silly, it’ll be nice to have company again.”
He smiles again but this one makes you feel a little more on edge, something about the way it doesn’t quite meet his eyes.
“Well then, I’m sure we’ll get on like a house on fire.”
You settle into a new routine, Leon fitting into your day to day pretty easily. He’s sarcastic and mouthy, but it beats only having yourself for company. Your husband dropped off his son in late January and it’s now early May; it’s like you blinked and realized you haven’t even had anyone else visit except for Leon’s actual mom. (She’s surprisingly a sweetheart and quite helpful even if she makes Leon all moody to have her in your shared space).
It’s after one such visit that left Leon in an irritable mood where you decide to have a little movie night in order to cheer him up. You’re unsure as to what started it this time, but the ex missus just gave you a quick smile and wave goodbye as Leon stormed off upstairs. Taking in a deep breath, you rap your knuckles on his closed door and listen for any movement.
Half a minute passes by before you hear him walk over and open the door. You take in his sweats and loose white tee. Good, it doesn’t look like he's headed out—you tilt your head before looking back up into his face.
“Yes?” He raises an eyebrow and crosses his arms, a corner of his lips ticking up into a half smile.
“Wanna watch some shitty horror movies and order pizza?” You smile, pleased with yourself when he drops his arms.
“Sure,” he shrugs, tossing his phone back onto his bedspread and pushing you away from his door, closing it behind him, “w’nna order a cheese pizza?”
“Sounds good,” you lead him back downstairs, flopping down on the couch and grabbing your phone.
Leon sits on the cushion next to you, leaning over to watch as you scroll through the app.
“Want any sides or anything?” You ask, attention still on your phone.
“Pizza’s plenty.”
You feel his breath ghost across your neck and it sends a chill down your spine. Scrunching your shoulders up, you laugh and bump against his side.
“That tickles, Leon,” you shift a little and you feel him move to face the television.
Once you place the order, you lock your phone and sink into the couch. Leon’s close enough you can feel his body heat, but you know if you move he’ll end up next to you again. It’s something you’ve noticed over the time that he’s stayed here; you’ve only brought it up once and he admitted he likes being close since he misses his mom.
You frown to yourself as Leon channel surfs, not wanting to start any movies only for it to be interrupted by the delivery guy. For him to miss his mom so much, he’s always pissy when she visits. Maybe he’s just salty that she let him end up living here with you? Glancing over at him, he notices you looking and shoots you a grin.
“Have any idea on what movie we start with?”
You return his grin and drum your fingers against your thigh, “Hmmm, you ever watch Spookies?”
He shakes his head, “I’m assuming it’s bad?”
“The worst but in the best way,” you laugh.
He studies you for a moment.
“Thanks for trying to cheer me up.”
Giddy warmth bubbles in your chest, “Of course, Leon. I know the situation probably isn’t ideal, but I’ll take care of you.”
He laughs low in his throat, “We’re nearly the same age.”
You wave him off, “Yeah, yeah, but I’m still older though.”
Lapsing into a companionable silence, you mindlessly watch as Leon zips through different shows until the doorbell rings. After stuffing your faces with pizza, you settle in comfortably on the couch, feet laying over Leon’s lap after he tugged your legs away from you.
“No reason to stay curled up like that,” he pats your calf.
Unsure how to feel, you eventually relax into him. If it doesn’t bother him, then why should it bother you? The heat from his lap must lull you to sleep because the next thing you know is blinking your eyes open to some random movie playing on the tv. Another beat and you groggily glance down your body at the new weight pressing you into the cushions.
Sandy blonde hair fills your vision as you feel Leon softly suck a nipple into his mouth. Without you noticing, he has pushed your flimsy shirt up and tugged your bra cups down. Squirming under him only leads to him sighing softly, eyes fluttering shut as he licks around your stiff peaks.
“Stop, stop,” you pant, feeling sluggish and out of sorts, arms and legs feeling wooden as sleep tries to cling to your senses.
Leon only laughs and goes back to softly sucking on your nipples, mouth drifting from one hard bud to the other with quick swipes of his tongue.
“But mommy, you said you’d take care of me,” his low voice raises the hair on your arms, “mmm, and what I really need is to suck your sexy tits.”
There’s no denying the rush of slick that fills the gusset of your panties.
“S’wrong, Leon,” you counter, weakly crying out when he gently bites your nipple.
“Maybe, but I think you need this, need me to take care of you. After all, my dad’s not going to,” he growls and roughly sucks the puckered skin around your stiff bud, “you need a husband who wants to stuff your hot little pussy.”
A loud keening moan leaves your mouth before you can clamp your lips shut.
His eyes are bright as a grin lights up his face, “See? C’mon, no one has to know that you let your stepson dick you down on the couch.”
Hips jumping, you mewl as he goes back to lapping at your nipples, hands coming up to grope the soft fat of your breasts.
“Been waiting for this,” he murmurs into your sternum, mouth leaving a trail of hot kisses across your skin, “fuck, I’ve wanted you so bad, mommy.”
The condescension in that one word makes you drip, pussy throbbing for more than just words.
“W-we shouldn’t though,” you try to get a grip on yourself, hands hovering over his hair, “god, I’m married to your father.”
“Is he here? Is he ever here?” He raises up and sneers at you, “never around when you need’em huh?”
Raising up onto his haunches he gives you a nasty smirk, “But that’s why you have me now. I’m gonna pound your hot little pussy day and night. Maybe it’ll even make you a real mommy.”
“Leon!” You gasp, nipples tightening at the thought, hands digging into the couch.
But he’s telling the truth. Your husband is never home— hasn’t called you back and barely replies to texts. You’ve been lonely and neglected even before Leon got here; so what if it’s wrong? It won’t kill anyone just to go along with him this one time. So that’s what you decide to tell him.
“This one time,” you whisper, biting your lip as you give in to him, “just once.”
He laughs, “Sure, I can work with that.”
Once turns into twice.
“It’s still just the one time,” you pant as he fucks into your squelching pussy, face mashed against the armrest of the couch, “it’s still the same round.”
“Sure, mommy,” he murmurs in your ear and you clamp down on him tighter, “whatever you say.”
Which turns into three and four and then five…
By the next afternoon, you're bouncing on your stepson’s fat cock in your own marriage bed.
“Fuck, fuck, I need it, please, I wanna cum,” you whimper, grinding down onto Leon’s dick, “please.”
“Take it then, mommy, take your son’s cock deep in that little pussy,” he growls, thumb rubbing your clit in tight rough circles.
“Yes, yes, yes,” you chant, eyes rolling back as Leon’s fat tip kisses your cervix, “god, it’s so good.”
“Yeah? Better than dad’s?” Leon asks, flashing you a smug little smile.
“Uh huh,” you whine, hands pressing on his broad chest so you can ride him harder, “you’re the best fuck I’ve ever had.”
“Goddamn,” he growls, grabbing your waist and flipping you onto your back.
Pulling halfway out, he bullies his cock back into your sopping wet hole, pace fast and hard making you wail as he rams against your g-spot.
“Tell me mommy, tell me who’s making this fat pussy feel so good,” he pinches your nipples, “c’mon mommy, say it.”
“You,” you whimper, tears clumping your lashes, “you’re making mommy’s pussy feel so good.”
“Who?”
“My son,” you cry out as he tugs your nipples roughly, “my son’s filling my pussy and making me cum.”
“Good girl, mommy,” he coos mockingly and you squeeze his cock, pussy walls snug and wet around his thick length.
“I’ve given you so many creampies,” he sighs, “fuck, I hope one of them takes. Wanna drink your milk.”
You shudder, hips stilling, “That’s so—”
“Hot?” He slaps your thigh and you start grinding on his cock again, “these tits leaking milk for me would be a dream come true. Let me breed you, mommy.”
“I can’t,” you mewl, clit throbbing as you rock your hips into his thrusts, “can’t get knocked up by my stepson.”
Leon groans, “It’ll just be the one time. Besides, I’ve been dumping load after load into this tight little cunt. We both know you want it, mommy. Making that pussy crave to have me stuffing her to the brim.”
You lean forward, face pressing against his neck as you moan brokenly.
“I shouldn’t,” you hiccup, hips writhing as Leon reaches underneath you to grip your ass.
“It’ll be our little secret,” he humps your pussy, cock knocking against your cervix and making you squeal, “let me breed you, mommy. Let your son breed your fat pussy.”
“I’m gonna cum,” you slur, mouth panting and drooling against his skin, “oh god, you’re gonna make me cum.”
“Next time, I want you to fight me,” he whispers in your ear and you moan, “fight me so when I pin you down, I’ll be raping your hot wet pussy until you cream all over my cock, mommy.”
Your nails dig into his back and you scream, orgasm wiping out your thoughts as your body thrashes under Leon.
“I’m cumming, fuck, mommy, gonna fill you up again,” he rambles, hips pistoning his cock in and out of your pussy as you continue to orgasm.
The last thing you see is Leon’s blue eyes staring down at you as your pussy milks his cock while he spurts rope after rope of thick cum inside your clenching hole.
You wake up sometime later with Leon running his fingers along your arm and shoulder.
“You okay?”
You hum and nod, stretching out along the bed, feeling a slight twinge in your hips.
“May’ve over done it,” you mumble, rubbing your eyes with the palms of your hands.
Leon laughs and drops a kiss to your head.
“Yeah I got that after you passed out.”
Giggling, you turn on your side to face him.
“Need to drink more water I guess.”
He nods, a funny sort of smile overtaking his features.
“You’re not gonna tell anyone right?”
You scoff and roll your eyes, “Why would I? Even if we’re both adults, I don’t think anyone’s gonna be happy it happened.”
Sighing, you push up until you can swing your legs over the side of the bed.
“I’m gonna take a shower.”
Standing up, your thighs shake but you’re able to walk over to the en-suite bathroom. At the doorway, you turn back to see Leon staring at you, a hungry look in his eyes. You bite your lip knowing what you’re about to say isn’t a good idea, but what the hell. You’re already in it this far.
“If you wash my back, I’ll wash yours,” tone flirty as you smile at him.
Not waiting for an answer, you walk into the bathroom, listening as the sheets ruffle from Leon climbing out of bed to follow you.
