The dim glow of the bedside lamp cast soft shadows across the room as Olivia leaned against the headboard, her fingers trembling slightly as she held the small, unmarked pill in her hand. Kellen stood by the bed, his broad shoulders framed by the light, his piercing gaze fixed on her. There was something unspoken between them, a tension that had been building for weeks. Tonight, she thought, everything changes.“You’re sure about this?” Olivia asked, her voice barely above a whisper. Her heart raced as she glanced down at the pill, its surface smooth and unassuming. Kellen smirked, that confident, knowing smirk that always made her insides melt. “Do you trust me?” he asked, his voice low and gravelly. It wasn’t a question—it was a challenge. She swallowed hard, her throat suddenly dry. “Of course I trust you,” she said, though her voice wavered. “It’s just… this is insane. What if it doesn’t work? What if it’s too much?”He stepped closer, his presence overwhelming, and took her chin in his hand, tilting her face up to meet his eyes. “It’s going to work,” he said, his voice steady, commanding. “And you’re going to look incredible when I fill you up.” A shiver ran down her spine at his words, and she felt her body respond in ways she couldn’t control. God, how does he do that? she thought, her resolve crumbling. Without another word, she popped the pill into her mouth and swallowed, her eyes never leaving his. Kellen did the same, the pill disappearing between his lips with a flick of his tongue. He smirked again, that damn smirk, and climbed onto the bed, straddling her hips with an ease that made her breath catch. “Now we wait,” he said, his voice dripping with anticipation. “And when it starts to work… you’re mine.”Olivia’s heart pounded in her chest as she felt the first wave of heat surge through her body. It started faint, like a warm flush creeping up her neck, but soon it was everywhere, a fire racing through her veins. She gasped, her fingers gripping the sheets as the sensation intensified. “Kellen…” she moaned, her voice trembling. “I feel… I feel hot.”“Good,” he growled, his hands sliding up her thighs, pushing her dress higher. “That’s exactly how you should feel.”She could already feel the difference in him, too— the way his body seemed to radiate heat, the way his muscles tensed with unspoken power. His eyes darkened, and when he leaned down to kiss her, it was suffocating, unstoppable. His tongue explored her mouth with a ferocity that left her dizzy, and she moaned into him, her hands tangling in his hair. When he pulled away, she was breathless, her chest heaving. “Kellen…” she whispered, her voice filled with need. “Shh,” he murmured, his hands sliding under her dress, tearing her panties off with a single, swift motion. “Just let me take care of you.”She didn’t have time to protest—not that she wanted to. His mouth was on her before she could even think, his tongue weaving a spell that left her writhing beneath him. She cried out, her back arching as he devoured her, his hands gripping her hips to keep her in place. The heat inside her was building, a pressure that threatened to erupt at any moment. She could feel it in him too— the way his body seemed to throb with need, the way his breath came in ragged gasps. When he finally pulled away, she was a mess, her body trembling, her mind clouded with desire. “Kellen, please…” she begged, her voice a desperate whimper. He didn’t need to be told twice. In one swift motion, he was on top of her, his body pressing hers into the mattress. She gasped as he entered her, his size overwhelming her in the best way possible. He moved slowly at first, savoring every inch of her, but soon he was pistoning into her with a ferocity that left her screaming his name. “Kellen!” she cried, her nails digging into his back. “Oh God, it’s so much… I can’t…”“You can,” he growled, his voice rough with need. “You’re going to take everything I give you.”She felt it then— the first hint of what was to come. A warmth, a pressure, a fullness that spread through her with each thrust. She could feel him swelling inside her, his body preparing to unleash what they had both been waiting for. “Kellen… it’s coming…” she moaned, her voice trembling. “Let it happen,” he commanded, his voice a low, guttural growl. “Let me fill you up.”And then it hit her— a wave of sensation so intense it left her gasping for air. She felt him pulse inside her, his release flooding her with warmth, with life. She cried out, her body convulsing as she was overcome with pleasure, her stomach beginning to swell with the sheer volume of his release. “Oh God, Kellen… it’s too much…” she whimpered, her hands instinctively moving to her stomach, which was already beginning to bulge. “No,” he said, his voice firm, his hands covering hers. “This is exactly how it’s supposed to be.” He continued to thrust into her, his release showing no signs of stopping. Her stomach expanded with each movement, the warmth inside her growing to an almost unbearable level. She could feel herself stretching, her body accommodating him in ways she never thought possible. “Kellen… I’m so full…” she moaned, her voice trembling with both pleasure and disbelief. “Good,” he growled, his hands moving to her stomach, rubbing the quivering flesh as it expanded beneath his touch. “You’re beautiful like this.” She could see it now— her stomach swollen as though she were carrying quadruplets, the skin stretched taut over the sheer volume of his release. She moaned again, her body trembling with the intensity of it all, her mind a haze of pleasure and desire. “Kellen… I can’t believe…” she started, but he cut her off with a kiss, his lips claiming hers with a ferocity that left her breathless. “You’re mine,” he said, his voice a low, possessive growl. “And this is just the beginning.” She could feel him swelling inside her again, another wave of release building. Her stomach continued to expand, the sensation overwhelming, all-consuming. She moaned into his kiss, her body trembling with the intensity of it all. “Kellen…” she whispered, her voice filled with need. “Don’t stop…”“I won’t,” he promised, his voice rough with desire. “I’m going to fill you until you can’t take anymore.” And as he continued to thrust into her, his release flooding her once more, Olivia knew there was no turning back. She was his— completely, utterly, his.

Olivia, with Kellen's reassurance, took a mysterious pill and waited as a heat surged through her body. Kellen, who had also taken the pill, devoured Olivia with intense passion, entering her and filling her with his release, causing her stomach to swell significantly. Despite Olivia's initial disbelief and discomfort, Kellen continued to thrust into her, promising to fill her until she could take no more.

The dim glow of the bedside lamp cast soft shadows across the room as Olivia leaned against the headboard, her fingers trembling slightly as she held the small, unmarked pill in her hand. Kellen stood by the bed, his broad shoulders framed by the light, his piercing gaze fixed on her.

“You’re sure about this?” Olivia asked, her voice barely above a whisper. Her heart raced as she glanced down at the pill, its surface smooth and unassuming.
