Ashley shifted restlessly in her bed, the sheets twisted around her legs. She was 18 now, but still lived with her grandparents while her parents were stationed overseas. It had been a lonely summer so far, stuck in the house with nothing to do. But things were about to get a lot more interesting. She heard the bedroom door creak open and tensed, eyes flying wide. Her grandfather stood in the doorway, a silhouette against the hall light. He was wearing nothing but a thin robe, the outline of his impressive cock clearly visible through the thin fabric. “Grandpa?” Ashley squeaked, pulling the covers up to her chin. “What are you doing?” “Shhh,” he soothed, stepping into the room and closing the door behind him. “Just me, sweetheart. I couldn’t sleep, so I thought I’d check on you.” He sat down on the edge of her bed, the mattress dipping under his weight. Ashley could smell the whiskey on his breath, see the glint of lust in his eyes as he gazed down at her. A slow, sinking feeling settled in the pit of her stomach. “Grandpa, I don’t think-” she started, but he cut her off with a finger to her lips. “Hush now,” he said softly. “Grandpa just wants to make you feel good, baby girl. I know it’s been a long, lonely summer for you.” His hand slid down to cup her breast through the thin nightshirt she wore, thumb rubbing over her nipple until it pebbled against his touch. Ashley shivered, a confusing mix of shame and desire churning inside her. “I-I shouldn’t,” she whimpered, even as her body arched into his caress. “It’s not right.” “Shhh,” he murmured again, leaning down to capture her lips in a searing kiss. His tongue delved into her mouth, plundering her with an intensity that left her breathless. “Let grandpa take care of you, sweetheart. I promise it will feel so good.” As if to prove his point, his hand slipped beneath the covers and into her panties, fingers finding her slick folds. Ashley gasped into his mouth as he rubbed circles over her clit, stoking the heat growing between her thighs. “That’s it, baby,” he crooned as he broke the kiss, his lips trailing down her neck. “Grandpa’s gonna make you feel all better.” He pushed a thick finger inside her tight channel, pumping slowly as his thumb kept up its relentless assault on her sensitive nub. Ashley bit her lip to stifle a moan, hips twitching as the coil of pleasure wound tighter and tighter in her core. “Grandpa…” she whined, eyes fluttering shut. “I’m…I’m gonna…” “Come for me, sweetheart,” he growled against her skin, adding another finger and curling them just right. “Let go for grandpa.” The dam burst and Ashley cried out, back bowing off the bed as an intense orgasm crashed over her. Her pussy clenched around his fingers as wave after wave of ecstasy flooded through her. Grandpa chuckled darkly as he worked her through it, not letting up until she collapsed back against the mattress, chest heaving. Then he drew his hand from her panties and brought his slick fingers to his mouth, licking them clean with a groan. “Fuck, you taste good,” he said hoarsely. “Now it’s my turn, baby girl.” He stood and shrugged out of his robe, letting it pool on the floor as his thick, hard cock sprang free. Ashley’s eyes went wide at the sight of it – long and girthy, the swollen head an angry red. It curved slightly upwards towards his toned belly, pulsing with each beat of his heart. Grandpa climbed onto the bed, crawling over her until he hovered above, his weight braced on his elbows. “I’m going to fuck this sweet little pussy now,” he promised, voice rough with need. “Gonna make you mine.” He hooked his fingers in her panties and yanked them down her legs, tossing them aside carelessly. Then he notched the broad head of his cock against her dripping slit, teasing her entrance. Ashley knew she should stop this, that it was wrong on so many levels. But the taboo thrill of it only served to heighten her arousal. She needed this – needed him – with a desperation that consumed all rational thought. “Please,” she whispered, voice quavering with want. “Please fuck me, grandpa.” With a groan of triumph, he surged forward, spearing into her tight heat with one powerful thrust. They both cried out at the intense sensation – grandpa grunting as her virgin walls stretched to accommodate him, Ashley keening as a sharp spike of pain mingled with the pleasure of being so thoroughly filled. He held still for a moment, letting her adjust to his size. Then he began to move, setting a deep, steady rhythm that had Ashley seeing stars. The obscene sound of flesh slapping against flesh filled the room as he fucked her with abandon, each thrust driving him deeper into her willing body. “Yes, yes!” Ashley chanted, nails raking down his back. “Fuck me harder, grandpa! I want to feel you for days!” Grandpa obliged, pounding into her with increased fervor. The headboard slammed against the wall with each powerful drive of his hips, the ancient wood creaking under the strain. He leaned down and captured her lips again, kissing her roughly as he fucked her into the mattress. Ashley could taste herself on his tongue – musky and sweet – and it only served to drive her higher. They moved together like animals in heat, lost to the desperate need building between them. Grandpa’s thick cock pummeled her sweet spot with ruthless accuracy, stoking the fire in her core until she was consumed by it. “Gonna come,” he rasped against her mouth. “Gonna fill this tight little cunt with my seed. Make you mine forever.” “Yes!” Ashley sobbed. “Do it! Come inside me!” With a hoarse shout, grandpa obeyed, hips slamming into hers one last time as he erupted deep in her clutching sheath. Ashley felt the hot splash of his cum painting her insides, triggering her own explosive climax. They clung to each other as they rode out the waves of pleasure, their moans and gasps the only sound in the dark room. Finally, grandpa rolled off of her and flopped onto his back, chest heaving. “That was…incredible,” he panted, reaching over to stroke her hair. “You’re such a good girl for grandpa.” Ashley hummed contentedly, nuzzling into his touch. Her body ached in the most delicious way, filled with the sticky evidence of their sinful deed. This was only the beginning, she realized hazily. She and grandpa had many more secrets to keep together…
