The Day He Matured

"Dear fucking God!" Jenny screamed, her voice a raw, guttural mix of ecstasy and agony as her stepdaddy's thick cock plunged in and out of her tight asshole.

She was splayed out before her daddy, Tim on her back, her slender legs hooked over his strong forearms, her body arching off the bed with every brutal thrust.

Tim's marital bed creaked under their weight, the same bed he fucked Jenny's mother in just last night. Tim knew that made what he and Jenny were doing even more wrong, but his fatherly concern wouldn't let him relent. His little girl needed him. He couldn't help but succumb to consoling her in hard times. He wondered if Lila, his wife and Jenny's mom, would see it that way if she knew of their… situation. Probably not.

Sweat glistened on Jenny's pale skin, her full breasts bouncing wildly as Tim sawed into her despite the guilt gnawing at him. His hips slammed against Jenny's ass cheeks with a rhythmic slap that filled the room while he thought of his wife. The two women's faces overlapped in his mind. They looked so damn alike. This was Lila's fault. She never let him fuck her ass.

"Oh, fuck, Daddy... yes, just like that," Jenny moaned and gasped, her blue eyes locked onto her daddy's, half-lidded with lust.

Her hands clutched at the sheets, knuckles white, as waves of pleasure rippled through her. She could feel every inch of his big dick stretching her ass, claiming her in the most forbidden way. It was wrong. They betrayed her mother over and over, but God, it felt so right. Her mother didn't deserve Tim.

Getting fucked by daddy had been her secret fantasy since Jenny met Tim when she was fifteen. At twenty-five, she got him to rail her ass every chance he gave her. It wasn't often enough for Jenny, because Tim would get suspicious about the story she had been feeding him for the last six years.

They started with fucking once a year. That turned into every six months and now it was every two to three months. She was wearing him down slowly, getting him used to fucking her behind her mother's back.

Tim groaned deeply, his breath coming in hot pants as he gripped her thighs tighter, pulling her closer with each stroke, desperate to sink deeper into her asshole.

It wasn't manipulation. It was love. Tim was having fun too.

"Fuck, baby girl, your ass is so goddamn tight," he muttered, his mind a whirlwind of guilt and bliss.

He'd known Jenny for ten years, stepping in as her daddy when he married her mother Lila. He loved Jenny like his own hell, more than that now. He'd never take advantage of her by fucking her outside of their deal. It was a source of comfort, nothing more.

Raw-dogging her ass after she had a break up was their dirty little tradition. A drunken night in her dorm room when I was nineteen started it all. Ever since, she would tell him when she needed him. He would step in and do his duty as her daddy.

"There you go, angel. Does that feel better?" Tim rasped, now fucking Jenny at a steady pace.

"Yes, God yes. This is why I can't keep a man, daddy," Jenny choked, her words half outcries and half moans of satisfaction.

She bit her lip, a sultry smile playing on i

my mouth, even as tears of overwhelming sensation pricked her eyes. Her pussy ached with neglect, dripping wet from the anal pounding her daddy was giving her. She loved how daddy filled her ass out completely, but her pussy needed a fuck too. Today, she was going to make it happen.

Tim chuckled from between his daughter's legs, his voice husky and strained as he panted, lost in heavenly bliss. "What do you mean, sweetheart? Why would daddy comforting his baby girl stop her from keeping a man?" he asked, though his mind flashed to fucking Lila last night.

His sweet, pure wife who would never dream of taking dick up the ass. Jenny's ass clenched around his dick like a vice, milking the shit out of his cock.

He groaned and thrusted deeper into her, savoring the heat coming off her ass. Enjoying the fucking was wrong, but fuck, it was a win-win. Lila got the vanilla sex she appreciated and he got this filthy release with his stepdaughter. No one got hurt. He convinced himself long ago that it wasn't a betrayal, since Lila didn't like anal anyway. He was very strict about never fucking Jenny's pussy. That was just for his wife.

Jenny giggled breathlessly, the sound turning into a sharp gasp as he fucked away at her ass, tearing it apart with his relentless rhythmic pounding.

"Ohhh, daddy. Nothing's wrong with them. They're great guys," she admitted, her body rocking back and forth on the bed, her toes curling in pleasure, legs flailing about in the air. "They just, no one stretches my ass like this. No one makes me feel like a filthy whore quite like daddy does."

Flattered and spurred on by her words, Tim's eyes darkened with possessive hunger.

"Daddy missed this ass so much, baby," he growled, fucking her even harder, his balls slapping against her asscheeks.

Guilt whacked him in the chest again, as he started longing for Jenny's break ups so he could have a reason to fuck her again.

"Sorry about the break up, baby," he added hastily.

The bedframe rattled, and Jenny squealed, her moans escalating into desperate pleas.

"His fucking loss. Daddy's gain. Rip my ass apart, Daddy! Fuck the shit out of me! Rail my cunt silly. God, yes!"

Tim's heart skipped a beat, hoping he'd misheard that last part. Fucking her pussy was too personal. They were never going there.

He groaned loudly, his voice rumbling like thunder.

"So fucking tight, Jenny. No matter how many times I fuck your ass, it's always like the first time." He slowed just enough to tease her, watching her squirm, then slammed back into her and started pounding her ass again. "Are you being good for daddy? Keeping other dicks out of this perfect ass?"

He knew he shouldn't have made this stipulation to their agreement, but Tim Peters was a possessive man. It was the only way he could 'let' Jenny date. Her boyfriends could have her slutty pussy… but her ass was his alone.

"Yes, Daddy. Only yours," she moaned, her hips bucking up to meet his.

Sensing that her daddy was at the height of ecstacy, Jenny decided that now was the perfect time to get what she wanted.

With a wicked glint in her eye, she purred, "But wouldn't you rather try railing my slutty pussy? Just this once? It's so wet for you, daddy."
