Brandy and Michael had always been close. Too close. Identical twins, twenty-one years old, same dark wavy hair, same sharp blue eyes, same sharp tongues. They shared everything growing up—rooms, secrets, even a bed when they were little. Now they shared a college campus, and tonight they shared a drunk, reckless hunger that had been building for years.
It was the last night of spring break. A massive beach party roared along the private stretch of sand their friends had rented. Bonfires crackled. Music thumped. Red cups floated everywhere. The ocean crashed black and endless under a full moon.
Brandy looked like sin in a tiny black mini-skirt that barely covered her ass, a cropped white tank that left her midriff bare, and nothing underneath. Her long legs glowed under the firelight. Every time she bent over to grab a beer, the short skirt rode up and flashed the smooth, bare cheeks of her perfect twin ass. Michael had been staring all night.
He was just as fucked up—shirtless, board shorts hanging low on his hips, abs glistening with sweat and ocean spray. He’d been hard for hours watching his sister dance like a slut.
By midnight both of them were wasted. Brandy stumbled over to him near the dunes, away from the main crowd, a half-empty bottle of tequila swinging from her fingers. Her short skirt was twisted, one strap of her tank hanging off her shoulder, nipple almost free.
“Mikey…” she slurred, voice husky. “You’ve been staring at my ass all fucking night.”
Michael laughed, but it came out rough. “Hard not to. That short skirt is barely legal, Bran.”
She stepped closer, pressing her soft body against his bare chest. Her hand slid down and cupped the thick outline of his cock through his shorts. “Mmm. Someone’s already hard for his twin sister.”
“Fuck… Brandy…”
“We’re both drunk,” she whispered against his ear. “No one can see us back here. And I want you to fuck me hard. But first… I’m going to fuck you.”
Michael’s eyes widened. “What?”
Brandy’s smile was pure evil. She reached into the little beach bag she’d been carrying all night and pulled out a thick black strap-on harness and a realistic 8-inch dildo she’d packed “just in case.” Her eyes glittered with pure twin lust.
“I’ve been dying to peg my brother. Tonight we’re doing it. You’re going to get on your hands and knees like a good boy while your twin sister fucks your ass.”
Michael’s cock jerked hard. He was too drunk, too horny, too deep in the forbidden to say no. “Jesus Christ, Bran…”
“That’s right. Say yes. Tell your sister you want her to fuck you hard.”
He swallowed. “Yes. Fuck me hard, Brandy. Peg your twin brother.”
She kissed him deep and filthy right there in the sand, tongues battling, tequila-sweet. Then she shoved him down onto a thick beach blanket half-hidden by the dunes. Music still thumped in the distance. Laughter and waves covered every sound.
Brandy straddled his chest first, short skirt hiked all the way up, bare pussy already glistening. She ground her wet cunt against his mouth. “Lick me first. Get me nice and ready while I put this on.”
Michael’s tongue dove in like he was starving. He licked and sucked her clit while she buckled the harness around her hips. The thick black cock jutted proudly from between her thighs, shiny with lube she poured over it.
When she was ready she flipped him over. “On your hands and knees, twin. Ass up. Short skirt stays on me the whole time so you can feel it against your back while I rail you.”
Michael obeyed, heart hammering. Brandy knelt behind him, spit on his tight hole, then rubbed the thick head of the strap-on against him. “Relax for sister… I’m going to fuck you hard.”
She pushed in slow but steady. The stretch burned deliciously. Michael groaned into the sand as inch after thick inch of his twin sister’s cock sank into his virgin ass.
“Oh fuck… Brandy… it’s so big…”
“Good,” she snarled, voice pure drunk dominance. “Take every inch of your sister’s cock. You’re my bitch tonight, Mikey. My twin slut.”
Once she was fully buried she started thrusting—deep, hard, relentless. The wet slap of her hips against his ass mixed with the crash of waves. Her short skirt flipped up over her own ass as she pounded him, the fabric brushing his lower back with every stroke.
“Fuck me hard,” Michael gasped, pushing back. “Harder, Bran. Ruin your brother’s ass.”
Brandy laughed darkly and really let loose. She grabbed his hips and railed him like she was trying to leave bruises. One hand reached around and stroked his leaking cock in time with her thrusts.
“You like getting pegged by your twin sister? You like feeling my short skirt slap against you while I fuck your tight ass?”
“Yes! Fuck yes! Don’t stop!”
She fucked him for long minutes until he was a babbling mess, then pulled out, flipped him onto his back, and mounted him reverse cowgirl so he could watch the strap-on disappear into his own hole while her bare, dripping pussy hovered inches above his face.
“Lick your sister while she fucks you,” she ordered.
Michael’s tongue attacked her cunt as she bounced on the dildo buried in his ass. Brandy rode him hard, short skirt flipped completely up, tits bouncing free now that she’d yanked the tank off. Milk-white breasts swayed as she dominated him completely.
They came together the first time—Michael shooting thick ropes across his own stomach while Brandy ground her clit against his tongue and soaked his face. But she wasn’t done.
She made him suck the strap-on clean, then bent him over a cooler and fucked him doggy again, harder, dirtier. “Say it. Say ‘fuck me hard, sister.’”
“Fuck me hard, sister! Peg your twin brother’s ass!”
Brandy reached under and jerked him off while she pounded. He came a second time untouched, clenching around the thick cock, milking it with his ass.
They moved closer to the waterline where the waves could hide them better. Brandy made him lie on his back in the wet sand, legs pushed to his chest, and fucked him missionary so she could kiss him while she ruined him. Her short skirt was soaked with seawater and her own juices. Every thrust made wet, filthy sounds.
“I love fucking my twin,” she whispered against his mouth. “I’ve wanted this for years. Your ass is so tight for me, Mikey. You’re going to take my cock whenever I want from now on.”
Michael’s eyes rolled back. “Anything… anything you want, Brandy. Just keep fucking me hard.”
She did. She fucked him until his hole was loose and puffy and leaking lube, until he came a third time just from the intensity. Then she finally pulled out, unstrapped the harness, and sat on his face so he could clean her pussy with his tongue while she stroked his spent cock back to life.
When he was hard again she sank down onto his real cock, reverse cowgirl, and rode him while facing the ocean, short skirt still on, flipped up so the cool night air kissed her bare ass. Michael gripped her hips and thrust up, fucking his twin sister’s dripping cunt while the last waves of the party roared behind them.
“Harder,” she moaned. “Fuck me hard, twin. Fill your sister’s pussy.”
He did. He came deep inside her with a broken groan, pumping load after load into Brandy’s eager cunt while she came again, squirting over his cock and balls.
They collapsed together in the sand, panting, covered in sweat, seawater, cum, and sand. Brandy’s short skirt was ruined. Michael’s ass ached in the best way.
She kissed him soft and filthy. “Next party we do it again. And next time I bring the bigger one.”
Michael laughed weakly, still buried inside her. “You’re fucking crazy, Bran.”
“I’m your twin,” she whispered, nipping his lip. “And now I’m the sister who pegs her brother whenever she wants. Deal with it.”
They stayed like that until the first light of dawn started to creep over the horizon—drunk, fucked-out twins tangled together on a beach blanket, the party long over, their secret sealed with cum and seawater.
And neither of them would ever look at a short skirt—or each other—the same way again.
