OH YES stepsister finally takes large fat cock of stepbrother

Oh, where to begin? This is going to be one wild ride, folks. So, picture the scene: there you are, minding your own business, when you hear a defiant “No!” Then some giggling. Suspicious, you creep down the hall to see what’s going on. And that’s when you spot them- your stepbrother and sister, going at it like rabbits.

Your sister, the little vixen, is on her knees, mouth agape as she takes in the sheer size of her stepbrother’s fat cock. He’s giving her a rundown of the anatomy of his dick, and she’s taking it all in, eyes wide.

“See, width matters too,” stepbro explains patiently, as he jabs a finger into the side of his shaft. “Feel that girth?”

“My god, it’s so thick,” she breathes, wrapping her hand around the base and giving it a squeeze. “And so warm and heavy…”

Stepbro groans, eyes fluttering shut. “Forget the banana. That’s nothing compared to this monster cock.”

Sister nods eagerly, continuing to stroke stepbro’s impressive manhood. “I’m so glad you showed me this, step. My BF’s dick is puny compared to yours. I don’t know why I wasted so much time on his little peewee.”

“Forget about him now,” stepbro growls, gripping her hair. “His name iswww!*uck!” His head falls back as she takes him into her mouth. She bobs her head eagerly, taking him deeper each time, until that cock is lodged down her throat.

Oh, the look on stepbro’s face – pure ecstasy. Back arched, mouth open in a silent scream, he lets her work that thick dick in and out of her wet mouth. She pulls back, gasping, and he takes over, grabbing her head and pumping into her face. Skin slaps against skin as he fucks her mouth hard and deep.

And then she’s getting up, climbing onto the bed. He joins her, shoving her flat on her stomach, plumping up her ass with pillows. “Don’t want to punish this fine rear too much,” he leers.

“What are you waiting for, step?” she teases from beneath him. “Quit fucking around and put it in me.”

“Fuck yes. No more ‘teases’,” he snarls. “From now on, you take my cock whenever I want.”

He grabs her hip, lining up his monster cock with her dripping cunt. Then he’s pushing in, inch by thick inch, forcing that sweet pussy open. “Take it, take it, take it,” he chants like a mantra, driving in deeper with each thrust.

She grasps the sheets, arching back, a thick cock studding her taut belly. “Fffuuuuck,” she whimpers. “I can’t – too fullll.”

But he’s not stopping until his balls are slapping her ass and she’s crying out her surrender. He pounds into her, the wet, obscene sound of flesh meeting flesh filling the air along with her whimpers and his grunts.

“How’s that fucking pussy, sis?” He flips her over, hammering into her harder, his heavy balls slapping rhythmically against her ass. “Getting dicked down by that fat cock of your stepbro’s?”

Sweat glistens on their intertwined bodies as he rails her into the mattress, her pussy blissfully stretched and stippled around that girthy cock. “Oh god, I’m gonna cum!” she shrieks, teens spasming as her pussy clamps down on him.

“Me too, sis…fuck!” With a roar, he slams in one last time, balls tightening, spurting hot ropes of cum into that eager cunt.

They collapse together, panting, boneless with sated lust. “You were right, step,” she sighs, nuzzling his neck. “That was the hardest I’ve ever come in my life.”

“Grew up, sis,” he murmurs, tucking a strand of hair behind her ear. “In more ways than one.”

She laughs breathlessly, giving his soft dick a parting lick. “I think it’s best if we make a regular thing of these ‘lessons’.”

“I like the way you think, sis,” he grins. “Expect a daily agenda with a different subject each day.”

Their eyes meet and they burst into giggles – the stepbrother with the monster cock and his horny stepsis, after one wild Windsor knot. Just the beginning of their sibling dirty school days.
