A Week In

The weeks after that explosive night turn Erin into something feral. She’s no longer just sneaking around—she’s craving the risk, the humiliation, the way your massive cock ruins her for anything smaller. Nick, bless his clueless 6’6” heart, still thinks he’s satisfying her. He has no idea his petite blonde fiancée is now your personal cum-dumpster, texting you timestamps of when she’s “taking a nap” so you can slip in and breed her while he’s downstairs gaming.

This particular Saturday afternoon the house is yours. Tawny is visiting family for the weekend. Nick is in the living room, sprawled on the couch in nothing but basketball shorts, his sad little package barely making a dent. You’re in the kitchen, shirtless, gym shorts slung low enough that the heavy root of your 8.125-inch monster peeks out. Erin saunters in wearing one of your old t-shirts—nothing underneath. The hem barely covers her plump ass, and those legendary head-sized tits sway hypnotically with every step, nipples stiff and obvious.

She glances toward the living room, then presses herself against you from behind, small hands sliding down to cup the thick weight of your cock through the fabric. “He’s right there,” she whispers, voice already husky with need. “And I’m dripping just from feeling this monster twitch. Nick’s clitty got hard when I kissed him good morning… but it’s so tiny I had to fake being impressed again.”

You turn, pinning her against the counter. Your heavy shaft grinds against her bare pussy, the fat flared head already smearing pre-cum across her clit. “Then show him what a real cock does to his future wife.”

Erin’s eyes sparkle with wicked delight. She drops to her knees right there in the kitchen doorway—visible if Nick just turns his head—and yanks your shorts down. Your monster springs free, slapping her flushed cheek with a meaty thwack. She moans loud enough for the sound to carry.

“Fuck… look at this thing,” she purrs, loud on purpose. “So much thicker than my fiancé’s pathetic baby dick. I can barely wrap both hands around it.” She demonstrates, her small fingers not even close to touching as she strokes your 6-inch girth. Nick’s head turns slightly on the couch, but he stays put, probably assuming she’s just grabbing a snack.

She makes out with your glans like a desperate lover—tongue swirling around the oversized head, sucking on the leaking slit, moaning filthily. “Mmmph—Nick’s whole cock is shorter than just this fat plum. I feel so bad for him… but it makes me so wet knowing I’m cheating with something real.”

You fist her blonde hair and feed her more. Erin gags happily, mascara already running as she forces more of your thickness past her stretched lips. Gluck-gluck-gluck. Drool cascades down her chin and onto those massive jiggling tits. She pops off with a gasp, strings of spit connecting her swollen lips to your throbbing meat.

“Baby?” she calls sweetly toward the living room, still stroking you with both hands. “Come here a second? I want to show you something.”

Nick wanders in, rubbing his eyes. He freezes when he sees his fiancée on her knees, face messy with spit, worshipping your superior cock. His shorts tent pathetically—barely a couple inches.

“Wha—Erin?!”

She giggles, nuzzling your heavy balls. “Look, babe. This is what a real man packs. Your little clit-dick is cute and all… but I need this now. Watch me take it. Watch how a proper cock stretches your slutty fiancée.”

Nick’s face burns crimson, but his tiny prick twitches visibly in his shorts. He doesn’t stop her. He just stands there, hand unconsciously palming his sad little bulge as Erin turns around, bends over the kitchen counter, and spreads her ass for you.

You rub the fat head up and down her soaked slit, teasing her until she’s whimpering. “Please Daddy… wreck me in front of him. Show him why I’m yours.”

You thrust in—pop—that massive glans stretching her open. Erin screams in ecstasy, her tight walls fluttering wildly around your girth. “Fuuuuck yes! It’s splitting me so good! Nick, baby, look how deep it goes—your little prick never reaches here!”

You start the grind—slow, deliberate circles that make her belly bulge obscenely with every rotation. Her massive tits swing and slap the countertop. Nick watches, mesmerized and humiliated, his hand inside his shorts jerking his 3.5-inch clit furiously.

Erin taunts him between moans. “See? This is what I sound like when I’m actually getting fucked. Not those fake little whimpers I give your baby dick. God, I’m such a size queen for stepdad cock now…”

You pick up speed, pounding her harder. The wet slap of your heavy balls against her clit fills the kitchen. Erin squirts violently—once, twice—flooding the floor while staring right at Nick. “I’m cumming so hard on a real cock! Your clitty could never make me do this!”

You pull out suddenly, spin her around, and lift her petite frame onto the counter. Legs over your shoulders, you spear back in, folding her in half. Those head-sized tits bounce wildly in Nick’s face as you rail her. Erin reaches out, grabs his hand, and makes him feel the bulge in her lower belly.

“Feel that, babe? That’s his fat glans rearranging my guts. Your whole dick is shorter than just the head. I love you… but I’m addicted to this monster now.”

Nick whimpers, stroking faster. You lock eyes with him and smirk. “She’s mine now, son. Watch a real man breed her.”

You bury deep and unload—thick, powerful ropes painting her womb white. So much cum it backflows immediately, dripping down her ass onto the counter in creamy rivers. Erin cums again just from the sensation, tongue hanging out, eyes rolled back in total cock-drunk bliss.

When you pull out, her pussy gapes obscenely, winking and pushing out thick globs of your seed. She scoops some up and feeds it to herself, moaning. “Mmm… tastes so much better than your watery little loads, babe.”

Nick explodes pathetically into his own hand, humiliated but unable to look away.

From that day, Erin’s descent accelerates into pure depravity. She starts “cuckolding” Nick more openly. Morning blowjobs for him turn into teasing sessions where she compares his tiny prick out loud while edging him. “Aww, look how cute it is—barely fills my palm. Meanwhile your stepdad’s cock stretches my jaw just from the head.” Then she sends you videos of her riding Nick reverse cowgirl, moaning exaggeratedly… only to sneak into your room right after, still leaking his weak load, and beg you to “fix” her with a proper fucking.

One evening you take it further. The three of you are on the couch watching a movie. Erin is between you, wearing a tiny skirt with no panties. She starts stroking you openly under a blanket while Nick is distracted. Your monster hardens in her grip. She leans over, whispers something to Nick, then climbs into your lap right there.

“Shhh babe, just watch,” she tells him as she sinks down onto your thick cock with a long, satisfied groan. “Fuck… so full. This is what I need every night now.”

She rides you slowly at first, massive tits bouncing under her shirt, while Nick watches from inches away. You reach around and rub her clit, making her squirt onto the couch. “Tell him, slut.”

“I’m sorry Nick… your baby dick is fun for playing with, like a little toy clit… but this monster cock owns me. I cum harder in five minutes with him than I have in our entire relationship.”

Nick’s hand is in his shorts again, jerking frantically. Erin laughs breathlessly and leans back against your chest, spreading her legs wider so he has the perfect view of your thick shaft stretching her. You bounce her harder, that fat glans battering her cervix until she’s screaming and shaking.

When you flood her again, she makes Nick clean her up with his tongue—licking your superior cum out of her wrecked pussy while she praises your cock and mocks his. “Good boy… taste what a real man leaves behind.”

The ultimate humiliation comes during a “date night” they planned. Erin cancels the fancy dinner and instead brings Nick to you. She strips him down first, giggling as his little 3.5-incher springs free—already leaking. Then she strips for you, dropping to all fours and crawling across the room like an eager pet.

“Watch this, babe,” she says, presenting her ass to you. You mount her like a bitch in heat—long, powerful strokes that make her massive tits drag on the carpet. Erin looks back at Nick the entire time.

“See how he owns me? Your clitty could never make me shake like this. I’m going to marry you… but I’m going to be his cock slut forever. Every time you fuck me with your tiny prick, I’ll be thinking about this fat, veiny monster stretching me open.”

You rail her through orgasm after orgasm until she’s a drooling, squirting mess. Then you pull out and paint her entire back and ass with rope after thick rope. Erin makes Nick lick every drop off her skin while she sucks you clean, moaning around your still-hard cock.

Later that night, after Nick has been sent to bed with blue balls and a ruined ego, Erin curls up in your arms, cum still leaking down her thighs.

“I’m completely yours,” she whispers, kissing the fat head of your cock reverently. “My body, my orgasms, my future… all for this big juicy cock. Nick’s little baby dick is just for teasing now. I love embarrassing him for you, Daddy.”

You reward her with another deep, grinding fuck—rotating those powerful hips, stirring her cum-filled pussy until she squirts again and passes out in cock-drunk bliss, whispering your name.

collapses back in my chair, fingers buried to the knuckles, panting like the desperate size-queen I am… Fuck, Daddy.
