The exclusive lingerie boutique was quiet and luxurious, with soft classical music playing in the background and racks of the finest lace, silk, and sheer fabrics displayed like art. Only a few other customers browsed the front of the store, giving Alex and Sophia plenty of privacy at the back where the large, private fitting rooms were located. Sophia's cheeks were already flushed from the morning sex they had shared in the hotel, and the tiny black thong she wore under her sundress was soaked again just from the anticipation.
Alex handed her another set — a sheer red babydoll with matching crotchless panties and a garter belt. "Try this one first, baby. I want to see how it looks on my new harem slut."
Sophia bit her lip, eyes sparkling with nervous excitement, and disappeared into the spacious fitting room. A few minutes later she called softly, "Ace… come in."
Alex stepped inside and locked the door behind him. The mirror reflected every angle. Sophia stood there in the red babydoll, the sheer fabric doing almost nothing to hide her heavy breasts or the dark nipples that were already hard. The crotchless panties framed her smooth, dripping pussy perfectly, and the garter belt made her thick thighs look even more delicious.
"Fuck…" Alex breathed, stepping close and running his hands over her body. "You look like pure sin."
He kissed her hard, tongues sliding together in a wet, hungry kiss while his fingers slipped between her legs and found her soaked folds. Sophia moaned into his mouth as he rubbed her clit in slow circles.
"We have to be quiet…" she whispered, even as she pushed her hips against his hand.
Alex smirked against her lips. "Then don't scream too loud when I fuck you in here."
He turned her toward the mirror, bent her forward slightly, and lifted the hem of the babydoll. His hard cock was already out, thick and throbbing. He rubbed the head up and down her slit, coating himself in her juices, then pushed in slowly, inch by inch, until he was buried deep.
"Ahhh… yes…" Sophia moaned, biting her lip hard to stay quiet as he started fucking her with long, deep strokes. The mirror showed everything — her heavy tits bouncing inside the sheer fabric, her face flushed with pleasure, Alex's cock disappearing into her pussy again and again.
"Watch yourself get fucked," Alex growled in her ear, one hand covering her mouth gently while the other rubbed her clit. "Watch how pretty you look taking my cock in the middle of a store."
Sophia's eyes stayed glued to the mirror, moaning into his palm as he fucked her harder. The wet sounds of his cock sliding in and out of her creamy pussy were barely masked by the soft music outside. They both froze for a second when they heard the saleswoman's footsteps nearby, but the thrill only made Sophia wetter.
Alex didn't stop. He kept thrusting, slow and deep, until Sophia came hard on his cock, her pussy clenching and milking him while she whimpered quietly into his hand.
They tried on three more sets after that.
The black lace teddy with open cups — Alex fucked her against the wall, her legs wrapped around his waist, sucking on her exposed nipples while she tried not to moan too loudly.
The white sheer babydoll with a tiny thong — he made her bend over the bench and took her from behind, pulling her hair gently so she could watch herself in the mirror.
The emerald green corset set — he sat on the bench, pulled her onto his lap in reverse cowgirl, and let her ride him slowly, her tits spilling out of the top while she bit her lip to stay silent.
Every time they almost got caught, the risk made Sophia cum harder. By the time they finally left the fitting room, her legs were shaky, her pussy was full of his cum again, and she had picked out over $4,000 worth of the sexiest lingerie pieces.
The saleswoman smiled knowingly as they paid. "You two look very happy together."
Alex just grinned. "She's mine now."
They drove straight back to Alex's new rented house — the beautiful modern villa-style home he had just moved into with the contract money. The moment the front door closed behind them, Alex pinned Sophia against it and kissed her like he owned her.
"Bedroom. Now," he growled.
They barely made it to the king-sized bed. Clothes flew off in seconds. Sophia was still wearing one of the new crotchless panties under her sundress. Alex pushed her onto her back, spread her legs wide, and buried his face between her thighs, licking and sucking her cum-filled pussy until she came again, screaming his name.
Then the real marathon began.
He fucked her in every position imaginable — slow and deep missionary while they kissed and talked about the future, hard doggy style while she begged for more, her on top riding him reverse cowgirl so he could watch her ass bounce, spooning while he played with her clit, even standing up against the wall like animals.
Every round ended with a creampie. Alex filled her again and again, pumping thick loads deep inside her until her pussy was overflowing and the sheets were soaked.
Between rounds they talked — really talked.
"I'm filing for divorce this week," Sophia whispered as she lay on top of him, his cock still buried inside her after the latest creampie. "I don't love him anymore. I want this life with you. I want the harem. I want you to take care of my son like he's yours. I want the villa. I want to be your good little sister with Emma."
Alex kissed her forehead, still slowly thrusting up into her. "It's already happening, baby. You're the second member of my harem now. Emma is your senior sister. We'll take care of you completely. You'll never have to worry about money or feeling unwanted again."
Emma joined them on video call again later, watching and touching herself while Alex fucked Sophia in slow, loving missionary. "You look so happy, little sister. Welcome to the family. We're going to share him and make every day feel like this."
The sex went on for hours — slow, intense, filthy, and deeply emotional. By the time they finally collapsed together, exhausted and satisfied, Sophia was a cum-drenched, glowing mess, smiling peacefully in Alex's arms.
"I'm yours forever," she whispered, kissing his chest. "Thank you for giving me this new life."
