Hazy morning light filtered through the thin curtains of Sarah’s bedroom, painting the rumpled sheets in soft gold. Sometime in the night they had migrated from the couch—half-asleep and still tangled, his arm heavy around her waist—until the narrow space gave way to the wider comfort of her bed. Sarah woke first, her head resting on Alex’s chest, the steady rise and fall of his breathing warm against her cheek. One of her legs had draped over his hip during the night, the bare skin of her inner thigh pressed to the hard length of him through his boxers. The unmistakable ridge of his morning erection nudged against her belly, hot and insistent.
A rush of shy heat flooded her cheeks. This is really happening. The thought looped through her mind, half disbelief, half wonder. She had fallen asleep listening to the quiet rhythm of his heart after the slow, teasing exploration on the couch, his hand curved possessively along the generous curve of her thigh. Now, in the gentle daylight, every detail felt sharper: the faint scent of last night’s wine still clinging to her skin, the subtle musk of arousal that had settled between them, the distant city hum filtering through the window like a reminder that the world outside still existed.
She didn’t pull away. Instead she shifted slightly, letting her hand drift down his chest, over the lean ridges of his abdomen, until her fingers brushed the waistband of his boxers. Alex stirred, a low rumble vibrating through his ribs. His eyes opened, sleepy and dark, a slow grin spreading across his face as he registered her touch.
“Morning,” he murmured, voice gravel-rough from sleep.
Sarah’s pulse quickened. She stroked him lightly over the fabric, feeling him thicken further under her palm. “Morning,” she whispered back, the word catching as his hips rolled once, chasing her hand.
He pulled her higher, mouth finding hers in a kiss that started deep and lazy, tongues sliding slow. His hands roamed freely now, no hesitation from the night before. He peeled the inside-out sleep shirt over her head, tossing it aside, and cupped the soft weight of her breasts, thumbs rolling her nipples until they tightened into aching peaks. Sarah arched into him, a quiet gasp escaping as she rocked against the hard line of his cock. She reached between them, freeing him from his boxers at last, and wrapped her fingers around his length skin-to-skin for the first time. He was thick and hot, velvet over steel, and she marveled at the way he pulsed in her grip.
Alex’s breath hitched. For a brief moment his thoughts flickered—She feels even better than the sounds I imagined—but then Sarah guided him, and the moment dissolved into sensation.
They rolled so he was above her, the mattress dipping under his weight. He kissed down her body with unhurried reverence: the hollow of her throat, the valley between her breasts, the soft swell of her belly. When he settled between her thighs there was no teasing this time. His mouth closed over her, tongue sweeping long and thorough from entrance to clit, two fingers curling inside her with perfect pressure. Sarah’s back bowed off the bed, a broken moan spilling free as pleasure coiled tight and fast. The morning light made every detail vivid—the way her thighs trembled around his shoulders, the flush spreading across her chest, the slick sounds of his mouth working her. He sucked her clit gently, fingers stroking that sensitive spot inside until her first orgasm crashed through her, sharp and bright. She clenched around his fingers, hips jerking, a cry caught in her throat as waves of heat rolled outward.
Alex stayed with her through it, gentling his touch until she softened, then crawled back up her body. Their eyes locked as he settled between her spread legs. Sarah wrapped her thighs high around his waist, ankles crossing behind his back, drawing him closer. The head of his cock nudged her entrance, slick and ready.
He sank into her in one slow, deliberate glide.
