Cindy was happy. Her stepbrother’s hand on her ass felt good as they walked through the mall. Her massive 34FF breasts bounced under her sweater; her short flouncy skirt swished against her tanned thighs.
She couldn’t help stealing glances at the impressive bulge in Tim’s tight jeans. Fuck, she thought, he’s hung like a donkey!
She and her stepbrother Tim were spending the afternoon in a town far from their own, where no one would recognize them. Here, they could openly be a couple—a gorgeous, voluptuous woman and her handsome companion—and no one would suspect they were actually stepsiblings who shared no blood. Sandy-haired Cindy had just turned twenty-one; Tim was twenty-three.
Everywhere they went, heads turned in their direction—or rather, toward Cindy. Because of her enormous breasts, of course. Cindy didn’t mind. She’d grown accustomed to the attention long ago. She loved having massive tits. They gave her power; they let her have any man she wanted. But right now, the only man she wanted was her big-dicked stepbrother.
“Babycakes?” asked Tim, his hand half on her hip and half on her ass.
“Hmmm?”
“Wanna buy some tops?” He openly ogled the vast expanse of flesh beneath her sweater.
Cindy smiled, revealing perfectly white teeth. “You mean,” she teased, “I should try on tops while you watch?”
“Well yes, my love,” Tim leered, squeezing her butt. “You know damn well what I mean.”
“While the salesgirls watch us, green with jealousy over my big tits?” pretty Cindy asked pointedly. “And you stare at me in my little skirt and tight top, taking forever to check me out in the dressing room mirror each time I try something on?”
“Oh yes,” murmured Tim, “that’s exactly what I had in mind.” He leaned forward and kissed his ravishing stepsister right on the lips.
“Ooo, Tim,” Cindy teased delightedly. “Are you sure you should kiss me like that? I am your stepsister, after all.”
Tim glanced quickly around to see if anyone had noticed. He couldn’t be certain, but a man standing nearby wore a stunned expression and stared right into their eyes. Upon reflection, Tim suspected the poor bastard might’ve just noticed Cindy’s stupendous tits for the first time.
Cindy herself didn’t seem worried about being overheard. She rubbed Tim’s muscular chest through his shirt. “Alright, Sock Buns,” she said brightly, “let’s go buy some tops.”
Sock Buns was one of her nicknames for him. Buns and hose. Cindy practically drooled every time she looked at her stepbrother’s tight, muscular little ass, and got wet just thinking about his big “sock.”
The shop they chose sold provocative clubwear and was called Minx. Two cute, impeccably dressed girls stood behind the counter. Their eyes widened when they saw big-breasted Cindy enter. Tim stifled a laugh—the sudden thought struck him that Cindy’s breasts were bigger than the girls’ heads.
“Can I help you?” asked the cute brunette.
Cindy smiled sweetly. “I’m looking for a top.” She slipped out of Tim’s arm and stepped toward them, her enormous breasts swaying slightly. “Something tight with lots of cleavage.”
Forty-five minutes and two thoroughly annoyed salesgirls later, Cindy and Tim left the mall entwined once more.
“Fuck me, Tim. I want you to fuck me,” Cindy whispered in his ear, her massive, firm breasts crushed against him. “It’s been weeks since we’ve had time alone.”
“We have to drive back in a few hours. We promised Mom we’d be home for dinner,” Tim answered, serious despite the desire swelling inside him. He thought for a moment, then asked: “Wanna get a room for a quickie? We passed motels on the way into town.”
Cindy rose onto her tiptoes and kissed him deeply. “Oh yes, lover. Let’s get a room.”
As soon as the motel door closed behind them, the stepsiblings grabbed at each other, desperate to undress and fuck. Time was short; foreplay was out of the question.
Cindy pushed away Tim’s groping, insistent hands and pulled off her sweater, revealing a truly massive bra straining to contain her mammoth breasts. “Quick, take off your pants,” she hissed.
She unbuttoned and dropped her little skirt, stepped out of her thong, and tossed both aside. Tim had gotten his jeans off but struggled a bit to free his giant erection from his briefs.
Famished, Cindy pushed him backward onto the bed and grabbed his nine-inch cock, guiding it into her tight, soaked pussy.
“Fuck me, Tim. Fuck me, stepbrother. Fuck your stepsister.” The filthy words tumbled from her mouth while the voluptuous twenty-one-year-old’s massive FF-cup breasts jiggled and swayed in her bra. She rode him hard, impaled on his shaft.
“My god, Tim, your cock is so fucking huge.”
Tim gripped her ass as she bounced on his thick pole. He raised a hand and seized one of her enormous breasts, savoring its weight, firmness, staggering size. Fuck me, he thought, they’re like basketballs.
He was tempted to flip her over and fuck her properly, but knew from experience she could cum fastest this way.
“Ooo, Tim,” Cindy panted, her Goliath tits—trapped in their bra—frantically bouncing above him. “I love your big cock. I love my stepbrother’s big cock in me. It’s so big…so goddamn huge.”
She bucked desperately up and down his enormous shaft.
“Cindy, baby,” Tim exhaled, loving how her tight cunt gripped him. He thrust upward, burying his long, thick dick inside her as she slid up and down.
The aroused stepsiblings fucked furiously like this for several minutes, their mounting ecstasy driving them wild. Some of the time Tim wriggled his way in to bury his face between her massive tits, and she grabbed the back of his head, mashing him into those soft, heavy mammary cushions.
They kept fucking. Tim felt his stepsister nearing the edge and timed his own climax to coincide with hers.
“Timmmyyyyy…I’m cummming!!!”
Tim let go, erupting inside his luscious stepsister, squeezing her mountainous mammaries as he shot thick geysers of cum deep into her convulsing pussy.
Cindy collapsed forward onto his chest, leaving soft, panting kisses on his neck and face.
Their privileged moment as lovers was over. It was time to return to that other world where everyone just knew them as stepsiblings.
Tim held her close, her immense breasts pressing against him, swelling between the two satisfied lovers.
