The weekend stretched before them like a promise whispered in the dark, Karen’s suitcase wheels clicking down the driveway as she left for her retreat. The house sighed into emptiness, doors locking with a finality that made Lila’s skin prickle. Ethan turned to her in the foyer, his eyes burning with that familiar hunger, the kind that stripped her bare without a touch. She wore a silk robe, loosely tied, the fabric whispering against her thighs as she stepped closer, her bare feet silent on the cool tile.
He didn’t speak. His hands found her waist, pulling her flush against him, the hard ridge of his cock pressing through his jeans like a demand. Lila’s breath caught, her nipples hardening under the silk, brushing his chest. His mouth claimed hers—rough, devouring, tongue thrusting deep as if to fuck her soul. She moaned into him, fingers clawing at his shirt, yanking it up to feel the heat of his skin, the ripple of muscles that tensed under her touch.
“Upstairs,” he growled, breaking the kiss just long enough to scoop her up, her legs wrapping around his waist. He carried her to the master bathroom, the one with the oversized tub and steam shower, kicking the door shut. The robe fell open, exposing her breasts, her shaved pussy already slick and aching. He set her on the counter, spreading her thighs wide, his gaze devouring her like fire on dry wood.
“Look at you,” he murmured, voice gravel and smoke. “Dripping for me already.” His fingers traced her inner thigh, teasing the edge of her folds, then plunged in—two thick digits, curling deep, stroking that spot that made her back arch, a gasp tearing from her throat. Water from the shower hissed on, steam filling the air, blurring the mirror like their boundaries.
Lila’s hands fisted his hair, pulling him down. “Eat me,” she begged, voice husky with need. He dropped to his knees, tongue lashing her clit—flat, broad strokes that sent lightning through her veins. He sucked, nipped, his fingers pumping relentlessly, the slick sounds echoing off the tiles. Her hips bucked, grinding against his face, chasing the edge. “Ethan—fuck—I’m coming—”
She shattered, pussy clenching around his fingers, juices flooding his mouth. He drank her down, growling his approval, then stood, stripping off his clothes in frantic pulls. His cock sprang free—thick, veined, the head purple and weeping. He pulled her into the shower, water pounding like rain on fevered skin.
Under the spray, he pressed her against the wall, lifting one leg over his hip. His fingers found her again, gentle now, circling her clit as water cascaded over them. “Remember the first time?” he whispered, lips on her neck, sucking bruises into her skin. “In the bath, when I told you no panties?”
She nodded, breathless, her hand stroking his cock—slow twists that made him hiss. “How could I forget? You own me.”
He thrust his fingers deeper, thumb on her clit, building her slow this time, loving the way she trembled. “And now? What if I want more? What if I want you forever?”
Her heart stuttered, but lust surged. “Take it. Take everything.”
He spun her, bending her forward, hands braced on the wall. Water sluiced down her back, over her ass as he spread her cheeks. His cock nudged her entrance, then slammed home—deep, claiming, balls-deep in one thrust. Lila cried out, the stretch burning sweet, her walls hugging him like velvet fire.
He fucked her hard, hips snapping, the slap of wet skin loud in the steam. One hand fisted her hair, pulling her head back for a bruising kiss; the other rubbed her clit furiously. “Come on my cock,” he commanded, thrusts turning savage, pounding her G-spot until stars burst behind her eyes.
She came with a scream, pussy spasming, milking him. He didn’t stop—pulled out, spun her again, lifting her against the wall. Legs around him, she sank down, impaling herself, riding him as water pounded their joined bodies. His mouth on her breasts—sucking, biting nipples until they throbbed. “Mine,” he grunted with every upward thrust. “All fucking mine.”
