Andy’s drive back to campus felt like crossing into another universe. The family home, once a playground of whispered touches and midnight risks with his sisters, now sat hundreds of miles behind him. Spring break had ended, but the fire it lit inside him burned hotter than ever. At 21, returning to his small off-campus apartment should have meant focusing on finals, parties, and normal college life. Instead, every mile marker reminded him of Jill’s skilled throat and Jenna’s tight, eager pussy clenching around him while they believed he was unconscious.

The first few days back were torture. Texts from Jill were casual on the surface—“Missed you already, little bro. Study hard!”—but carried hidden heat. Jenna’s messages were more obvious: heart emojis, “I keep thinking about our late nights,” and once, a blurry selfie of her biting her lip with the caption “Wish you were here to help me sleep.” Andy kept up the act, replying like nothing had happened, all while stroking himself to memories of their forbidden nights.

By Thursday, the plan was set. Jill had convinced their parents she needed to visit a “college friend” near Andy’s campus for the weekend, and she was bringing Jenna along for a sisterly road trip. Their parents, still oblivious, wished them safe travels. Andy cleaned his apartment, stocked drinks, and prepared the bedroom with fresh sheets that he knew would be ruined by Sunday.

The knock came Friday evening just after sunset. Andy opened the door to find both sisters standing there, looking every bit the tempting taboo fantasy. Jill, 24, wore tight jeans that hugged her athletic curves and a low-cut top showing the swell of her full breasts. Jenna, 18 and glowing with fresh confidence, had on a short pleated skirt and a cropped hoodie that barely contained her perky tits. Their eyes sparkled with shared secrets.

“Hey, sleepyhead,” Jill teased, stepping inside and hugging him tightly. Her body pressed against his, and he felt her nipples harden through her top. “Ready for a fun weekend?”

Jenna followed, her hug lingering longer, her small hand brushing deliberately across the front of his pants. “I’ve been wet the whole drive,” she whispered in his ear before pulling back with an innocent smile.

They ordered pizza and cracked open beers, keeping the conversation light at first. But the air thickened quickly. After eating, they moved to the couch for a movie. Jenna sat on one side of Andy, Jill on the other. Within twenty minutes, Jenna’s hand was resting on his thigh, inching higher. Jill’s fingers traced patterns on his arm, her breath warm against his neck.

“Remember how you always pass out after drinking?” Jill said softly, her voice dripping with suggestion. “Maybe we should have a few more beers so you can… relax.”

Andy played along perfectly. He drank enough to seem buzzed but stayed sharp. When he “passed out” on the couch two hours later, the sisters exchanged excited glances.

“Poor Andy,” Jenna giggled. “He’s out cold again. Just like at home.”

They helped him to the bedroom, stripping him slowly. Andy kept his body limp, breathing steady, but his cock betrayed him by hardening the moment their hands touched his skin.

“Look at that,” Jill murmured, wrapping her fingers around his thick shaft. “Even in his sleep, he wants us.”

The weekend exploded from there. What started as their usual secret oral ritual evolved into something deeper, riskier, and far more intense now that they were away from parental eyes. In the privacy of his apartment, the sisters dropped almost all pretense of caution.

Jill took the lead first, just like at home. She knelt between his spread legs and swallowed him to the root, her throat contracting around his length as she moaned. Jenna watched for a moment, then joined, licking and sucking his balls while her older sister bobbed. Their tongues met constantly, sloppy and eager, coating his entire groin in saliva and lust.

But Jenna had grown bolder. “I want to ride him while he’s like this,” she said, voice husky. She climbed on top, facing away from him in reverse cowgirl, and sank down slowly onto his cock. Her tight walls stretched beautifully around him, still so new to the sensation. “Fuck… he fills me so perfectly, Jill. It’s like his body was made for us.”

Jill straddled Andy’s face, lowering her dripping pussy onto his mouth. His tongue responded “instinctively,” licking deep into her folds, flicking her clit while she ground against him. The sisters faced each other, making out passionately as they rode their sleeping brother. Jenna bounced faster, her ass cheeks slapping against his hips. Jill pinched her little sister’s nipples, whispering filthy encouragement.

“Cum on his cock, baby. Let him feel how much you need him.”

Jenna came hard, her pussy gushing around him, soaking his balls. The sensation pushed Andy over the edge, and he flooded her depths with thick ropes of cum. Jill came seconds later on his tongue, thighs trembling as she gripped Jenna’s shoulders for support.

They didn’t stop. After cleaning him with their mouths, they switched. Jill rode him hard this time, her stronger body slamming down with more force. Jenna sat on his chest, facing Jill, and the sisters tribbed right above his stomach while Jill fucked him. Their wet pussies rubbed together, leaving slick trails on his skin. Andy could smell their combined arousal—sweet, musky, utterly addictive.

Hours passed in a blur of positions. They moved him around the apartment like their personal toy. In the living room, they bent him over the couch arm and took turns riding him from behind while the other sat on his face. In the kitchen, Jenna lay on the counter with her legs spread while Jill guided Andy’s “sleeping” hips to thrust into her. They even tried the shower, where warm water cascaded over their bodies as both sisters knelt and worshipped his cock together, competing to see who could deepthroat him longer.

By Saturday afternoon, after a short nap where the sisters cuddled naked against him, the energy shifted toward something more emotional. While they still believed he was unaware, their whispers revealed deeper feelings.

“I think I’m falling for this… for him,” Jenna confessed softly, tracing circles on Andy’s chest. “It’s wrong, but it feels so right when I’m full of him.”

Jill kissed her forehead. “I know. I’ve wanted him for years. This secret has made me realize how much I love sharing him with you. Our little family bond… it’s stronger now.”

They made love to him again, slower this time. Tender. Jill rode him in missionary, staring into his closed eyes with genuine affection while Jenna kissed along his neck and shoulders. When he came inside Jill, Jenna licked it out of her sister, sharing the taste in a long, cum-filled kiss above him.

The riskiest moment came Saturday night. They decided to take the game outside. Andy’s apartment had a small private balcony overlooking a quiet courtyard. Under the stars, with distant city lights twinkling, the sisters stripped him completely and laid him on a blanket.

Jenna went first, mounting him under the open sky. “Anyone could see us,” she whispered excitedly, riding him with rolling hips. Jill stood behind her, reaching around to rub her clit while kissing her neck. The thrill of possible discovery heightened everything. Andy’s cock throbbed harder inside Jenna as she came, moaning into the night air.

They switched, Jill taking him deep while Jenna sat on his face. A light breeze cooled their heated skin. When Andy filled Jill, the sisters knelt side by side, asses raised, and he “reflexively” took turns fucking them doggy-style. Their combined moans echoed softly. He came across both their backs, and they rubbed the cum into each other’s skin like lotion.

Back inside, they showered together again, soaping each other’s bodies and Andy’s, turning cleaning into another round of slow, sensual fucking. Jenna lost her virginity to anal that night—slowly, carefully, with lots of lube and Jill’s guidance. “Relax, baby. Let him stretch you. It feels so good once you adjust.” Jenna’s whimpers of pain turned to pleasure as she pushed back against him, taking every inch while Jill rubbed her clit.

By Sunday morning, the apartment reeked of sex. Sheets were stained, surfaces wiped but memories permanent. The sisters packed reluctantly, but not before one final marathon session.

This time, they tied Andy’s wrists loosely to the headboard again, just like the risky night at home. Both girls were insatiable. They rode him in every position imaginable. Jenna came three times on his cock. Jill squirted across his chest while grinding on his face. They finished by double-teaming him with their mouths, tongues swirling, until he exploded across both their beautiful faces.

As they cleaned up and dressed, the goodbye felt heavy. Jenna kissed his forehead tenderly. “Thank you for being our sleeping prince, Andy. I wish you could know how much we love you… like this.”

Jill lingered longer. “This isn’t the end. We’ll find ways. Holidays. Weekend drives. Our secret stays safe.”

They left, waving cheerfully as they drove off, still believing their brother remained completely oblivious to their taboo desires.

Andy lay in bed for a long time after they were gone, staring at the ceiling with a satisfied smile. The weekend had been beyond anything he imagined. His sisters were hooked—addicted to his body, to the thrill, to each other through him. The pretense had given them freedom to explore without shame.

But as he replayed every moment, he knew the game couldn’t last forever. The love mixed with lust was real. The bond was unbreakable now. One day soon, during the next visit, he would “wake up” mid-thrust. He would look them in the eyes, confess he had known all along, and pull them both into his arms for fully conscious, open family love.

Until then, the secret nights would continue—magnetic, dangerous, and utterly delicious. Their forbidden story had only just begun its next chapter, with spring break memories fueling countless more encounters. Andy closed his eyes, already planning the next “sleepover.”

The three siblings had crossed every line, and none of them wanted to go back. In their twisted, loving world, family had never felt closer.
