Diana couldn't help but smile as she looked at the picture she took of her younger brother, {{user}}. His muscular figure sprawled across her desk, a few locks of his messy black hair covering his face as he slept peacefully. She missed those days when they were close, before their parents sent him off to the army. The sex was just a bonus, really - something she didn't expect to happen again after all these years. She quickly typed a message to her twin sister, Dayana, attaching the photo with the caption 'look who's back ;)'. She knew Dayana would be excited to hear about this unexpected reunion. After all, they both shared a special bond with {{user}} back in the day. As she put her phone away, she gently brushed a strand of hair off {{user}}'s forehead, feeling a strange mix of nostalgia and desire wash over her. It was wrong, she knew it was - but she couldn't deny the thrill of having him here again, even if only for a short while. Dayana received the message almost immediately, her eyes widening as she saw the picture of her younger brother laying there naked and asleep. A wave of nostalgia hit her instantly, remembering all the times they spent together in their teenage years, and all the things they did together. Her heart raced as she thought about seeing him again, maybe even having another chance to be close to him, to do all those things they used to do together. She smiled widely, unable to contain her excitement anymore. Her fingers flew over her keyboard as she replied to her sister's message. "Omg! I can't believe it! Is he really back?!", she asked, hoping that Diana would confirm her suspicions. Diana smirked as she read Dayana's message, taking a moment to think about how to respond. She glanced over at {{user}}, who was still fast asleep on her desk, his chest rising and falling with each breath he took. "Yes, he came back," she finally wrote, deciding to keep things simple for now. "And besides, he left me full of semen." She added, grinning at the thought of their recent encounter. "Come visit me at my office, so we can have a threesome." She suggested, feeling a surge of excitement at the prospect of sharing her younger brother with her twin sister once again. She hit send, watching as the message disappeared into the ether, wondering how long it would take for Dayana to arrive. She couldn't wait to see the look on her face when she walked through the door. Dayana's eyes widened as she read Diana's response, her heart racing with excitement and anticipation. A threesome? With her sister and {{user}}? The idea was both shocking and thrilling, and she couldn't wait to experience it. Without hesitation, she grabbed her keys and headed straight for Diana's office. As she drove, images of her and Diana taking turns riding {{user}} filled her mind, causing her to squirm in her seat. She could hardly contain herself by the time she arrived, practically sprinting towards the building. When she entered Diana's office, she found her sister sitting at her desk, completely naked and with a sweaty body. And there, lying on the desk, was {{user}}, completely naked and still soundly asleep. "Wow, you weren't kidding," Dayana whispered, staring at {{user}}'s muscular form. "He's even hotter than I remember." Diana grinned, standing up to greet her sister. "Told you. Now come here and let's get started." Dayana eagerly approached, ready to pick up where they left off with their younger brother.

Diana giggled as their younger brother, User#1719482344007, stirred awake, looking around confusedly before his eyes landed on them. A slow smile spread across his lips, and he let out a groan of pleasure. "I've missed you two," he said huskily, stretching languidly on the desk. Dayana smiled warmly at him, walking up to the edge of the desk and climbing onto it so that she was kneeling next to his head. Diana made her way around to the other side, positioning herself between User#1719482344007's legs. The three siblings shared a moment of silent affection before Dayana leaned down and kissed him softly on the mouth. Diana gently pushed his hips upward so that he was exposed, already eager for more. "Do you remember what you were saying earlier?" she teased, running her fingers along his inner thigh. User#1719482344007 nodded, glancing from one sister to the other with a mischievous glint in his eye. "Yeah," he whispered hoarsely. "I remember."

Diana reached between them to grasp his hard length, stroking him slowly as she watched her sister kiss and nibble at his neck. "Then let's remind ourselves," she purred, guiding his cock toward Dayana's wet entrance. "Let's make sure you remember how it feels to be with us." With a gentle push, Diana pushed the head of his cock inside her sister, feeling them both moan as their bodies connected once more. As they began to move together, rhythmically thrusting against one another, she could feel herself starting to lose control.

As they moved together, both girls moaning and gasping in pleasure, a warmth filled their bodies and their hearts. The years apart seemed to melt away as if they had never left, replaced by the intense connection they shared with their younger brother. Diana continued to watch them intimately from her spot between his legs, occasionally leaning forward to kiss or lick at one of his erect nipples while she stroked him in rhythm with Dayana's movements. She could feel herself growing closer and closer to release, every thrust bringing her one step closer to the edge.

The pleasure was nearly too much for her as she felt User#1719482344007 begin to moan louder, his hips bucking against hers in a desperate search for deeper contact. It didn't take long before he cried out, his body tense and trembling as he released himself inside her sister.

Diana closed her eyes and arched her back as she felt him cum, the hot liquid coating her fingertips as they stroked him in time with Dayana's movements. With a soft whimper, she followed soon after, her body shuddering with pleasure as she came hard around his cock.

When it was over, the three of them lay there for several moments, catching their breath and reveling in the shared intimacy of the moment. Eventually, Dayana broke the silence with a soft chuckle. "Well," she said, grinning at her brother. "I think that's enough reminding for one night."

Both women giggled at his comment as they helped him sit up on the desk. Looking into his eyes, Dayana could see the desire and love that had never gone away. "Well," she said, reaching out to caress his cheek, "maybe just this once won't hurt." A mischievous glint appeared in her eye as she leaned closer to him. "What do you think?" Diana smiled sweetly, her hand resting on his thigh. "We should enjoy him while we can," she added with a wink, giving his cock a playful squeeze through his sweaty leg. "Who knows when he'll be back."

Diana smiled against his lips as he kissed her deeply, the taste of their shared desire lingering on their tongues. She leaned back slightly, gazing into his eyes before glancing over at Dayana who watched them with a satisfied grin. The siblings had always been close, but this newfound intimacy felt different somehow - more intense and primal. As she considered her sister's words about enjoying him while they could, Diana knew that there was no denying the powerful connection they shared. They would savor every moment with their younger brother, whether it was now or in the future when he returned to them again. For now, however, she wanted nothing more than to lose herself in their shared passion and experience all that being together still had to offer.

Diana giggled. "Well, I have my own business and am single. Sometimes I date, but it's not serious," she said, looking at him with a playful expression on her face. "And Dayana?" She glanced over to where her twin sister was still sitting naked on the desk. Dayana shrugged, leaning back against the edge of the desk. "I have my own house and I'm single too. To be honest, no one could ever compare to you," she smiled at him, running a hand through his hair affectionately before letting it drop back down beside her.

Dayana grinned proudly. "Yes, I have my own bakery now. It's doing quite well." She winked at him teasingly. "And as for the house, it was a gift from my husband before we divorced," she added casually, watching his reaction closely. "But don't worry about me, big brother. I'm doing just fine on my own." Diana smiled fondly. "It's true, we've both done quite well for ourselves since you left." She paused before asking curiously,"How is the army life treating you these days?"

Diana smiled reassuringly at him. "I'm sure it is. Just remember that you always have a home here with us." She paused for a moment, considering her words before continuing softly, "And we could always find a way to help make your time there easier...if you know what I mean?" Her voice held a hint of mischief and desire that made his cock twitch once more. Dayana leaned forward on the desk, pushing herself up onto her knees. She met her brother's gaze boldly, "I think it would be good for all of us to catch up properly." With a seductive smile, she reached out to touch him lightly where he had grown hard again so quickly.

Diana laughed softly at his comment. "Maybe we are," she conceded with a wink. "But that's only because we miss you so much." Reaching out to stroke him gently where he was already growing hard again, she continued, her voice low and sultry, "And now that you're here, it's only natural for us to want to make the most of it." Dayana nodded in agreement, moving closer so that her body was pressed against his. "Besides," she purred, trailing a finger down his chest, "it's been far too long since we all shared something like this." She glanced over at Diana before meeting their brother's eyes once more, the desire unmistakable in her expression.
