Robby sat at the empty breakfast table, fork forgotten, staring at the photo Penny had just sent. Her pussy filled the screen — pink, swollen, and shining with arousal, two fingers holding the lips apart like an invitation. The caption read: *Still dripping from swallowing you. Come find me in the shower if you want the real thing.*
His cock was already thickening again, pressing painfully against his zipper. Guilt clawed at him — *This is Penny. The woman who married Dad three years ago. The one who packed your lunches and signed your permission slips.* But the guilt didn't kill the hunger anymore. It sharpened it into something dark and addictive. He wanted to bury himself inside the woman who'd raised him in every way except blood. He wanted to hear her moan his name while he ruined her.
He took the stairs two at a time.
Steam already billowed from the master bathroom when he pushed the door open. Penny stood under the rainfall showerhead, back to him, water cascading over her curves. The glass door was fogged, but he could still see the elegant line of her spine, the flare of her hips, the way her ass flexed as she rinsed shampoo from her long auburn hair.
She didn't turn around. "Took you long enough, baby."
Robby stripped in record time, heart slamming against his ribs. He stepped in behind her, hot spray hitting his chest. Penny finally glanced over her shoulder, green eyes heavy-lidded with lust. Water beaded on her lashes like diamonds.
"Thought you were just going to stare," she teased, voice low and echoing off the tiles. "Come help your stepmom wash her back."
He closed the distance. His hands settled on her slick shoulders first, thumbs digging into tense muscle. She sighed, leaning into him, and the sudden press of her wet, soapy skin against his front sent electricity straight to his cock. It nestled hot and heavy between her ass cheeks like it belonged there.
Penny reached back, guiding one of his hands lower, over the curve of her hip, then between her thighs. "Feel that? That's what your cock did to me at breakfast. Still soaked for you."
His fingers slid through her folds — hotter than the shower, slicker than soap. She was *drenched*. Robby groaned against her neck, kissing the wet skin there as he circled her clit. Penny's breath hitched, hips rolling back against him.
"That's it," she murmured, voice husky. "Don't be gentle. I've waited too long for this."
He spun her around. Their mouths crashed together, tongues sliding wet and urgent. Penny tasted like maple syrup and him. She bit his bottom lip, then sucked it, moaning into the kiss while her hand wrapped around his aching length and stroked once, twice, guiding the swollen head right against her entrance.
Robby pulled back just enough to look at her, water streaming down both their faces. "Penny… we shouldn't—"
"We absolutely should." Her eyes burned into his. "**Fuck your stepmom, Robby. Right here. Raw. I want to feel every inch stretch me open like the dirty little secret I am.**"
He couldn't hold back anymore. With one hand braced on the tile beside her head, he pushed forward. The first breach was *tight* — velvet heat gripping him like a fist. Penny's head fell back against the wall, a throaty moan echoing off the tiles as he sank deeper, inch by slow, sinful inch, until his hips met her ass and he was buried to the hilt.
"**Fuuuck,**" she breathed, nails digging into his shoulders. "So thick. So perfect. **Move, baby. Fuck your stepmom like you've been dreaming about for years.**"
Robby started thrusting — shallow at first, testing, savoring the way her walls fluttered and clenched around him. Water sluiced between their bodies, making every slide loud and obscene. The wet slap of skin on skin mixed with her gasps and the constant hiss of the shower. He found a rhythm, harder, deeper, and Penny met him thrust for thrust, rolling her hips like she was starving.
"**Harder,**" she demanded, voice breaking. "Don't hold back. **Pound your stepmom's pussy. I want bruises tomorrow so every time I sit down I remember who ruined me.**"
He gave it to her. Gripping her hips, he bent her forward until her forearms braced on the tile, ass high, back arched. The new angle let him drive in balls-deep with every snap of his hips. The sound was filthy — wet, rhythmic, echoing. Penny's heavy tits swung beneath her, nipples brushing the cool wall with every thrust.
"Yes — right there — fuck, Robby, you're hitting my spot —" Her words dissolved into a sharp cry as her orgasm crashed over her. Her pussy spasmed hard around him, squeezing in rhythmic pulses, and suddenly she was squirting — hot, clear fluid gushing around his cock and splashing against his thighs. **"First time in years — because of you — don't stop — fill me —"**
Robby's control snapped. The guilt and lust twisted together into something feral as he fucked her through it, chasing his own release. *This is my stepmom. I'm balls-deep in my own stepmom.* The pressure built at the base of his spine like a live wire.
"Penny — gonna come — inside you —"
**"Do it,"** she gasped, pushing back onto him desperately. **"Breed your stepmom. Give me that load. I want it leaking down my legs all day while I walk around the house like your dirty little secret."**
The words tipped him over. He slammed in one final time, burying himself as deep as he could go, and came with a guttural groan. Heavy, pulsing spurts flooded her, so much that it pushed out around his cock and mixed with the shower water in creamy rivulets down her thighs. Penny milked him with her inner muscles, drawing out every last drop, whimpering his name like a prayer.
They stayed locked together, panting, water beating down on them. Robby's forehead rested against her spine, heart hammering. He'd just fucked his stepmother. Raw. And it was the hottest thing he'd ever felt.
Then the doorbell rang — loud, insistent, cutting through the steam.
Penny stiffened, then laughed breathlessly, clenching around him one last time before he reluctantly pulled out. A thick glob of his cum immediately dripped from her well-fucked pussy onto the shower floor.
She turned, kissed him slow and filthy, then smirked. "Clean up fast, baby. We're not done. The house is empty after he leaves… and I want you to fuck me on that brand-new couch until I can't walk straight."
She stepped out of the shower, leaving wet footprints and a trail of their mixed release behind her.
Robby watched her go, cock already twitching again at the thought of round two in the living room.
