The Dream Invader (Female POV, Brother-Sister )

I selected the "****" prompt from the Kinktober 2025 prompt list, hence this is my first time ever writing an **** story.

It began innocently enough. Stacey complimented her brother for finally getting in shape. If her eyes lingered a little too long on his chest, it was probably from surprise rather than arousal. That night, however, the first of October, she saw him in her dreams. The scene played out again but this time his shirt had been unbuttoned and her eyes had lingered longer. She brushed it off the following day.

'I just need to get laid,' she muttered to herself. She went out drinking that night, let some guy take her back to his apartment. The sex was good, not great but enough to clear her head. In the morning, though, she was visited by an even stranger dream. She'd woken up, only to find herself in her brother's bed and herself in his loving embrace. Her heart beat faster and she thought she might scream but she was jolted awake, realising that it was just a dream. The guy she'd actually slept with didn't want anything to do with her and kicked her out quite rudely. All the rest of the day, she'd contrasted that with how gentle her brother had been in the dream.

Drew seemed more confident over the following weeks. He'd always been a dork - some unfortunate mix of goth and nerd - but now he was managing to make her smile, even laugh. Sometimes, she had trouble distinguishing between the Drew in her dreams and the one in real life. After about three weeks, she cracked. Startled awake by a particularly erotic dream, she slipped her hand beneath her panties and pleasured herself.

'Drew,' she dared only whisper, as her head tossed and turned and her body writhed. She enveloped two fingers and tried to imagine him on top of her, thrusting into her. Her climax embarrassed her as much as it relieved her and she began trying to avoid her brother from then on.

She and her friends always wore slutty costumes for Halloween. There was always some party or other they were invited to. This year, however, she couldn't help but wonder what Drew would think of it. She'd never given it a second thought before but, now, she imagined his gaze falling on her generous cleavage. Part of her hoped his mind was filled with thoughts as impure as hers. Not because it made it more likely that they'd cross that uncrossable line, she assured herself, but because he deserved to experience the hell he'd been putting her through.

When the night finally came, she made sure to ask for his opinion on her costume, which was basically just a black leotard, cat ears and a painted nose and whiskers. Any other year, he'd have been awkward and wouldn't have even opened his bedroom door all the way. Tonight, however, he welcomed her in. His room, which had once been filled with junk, centring entirely on his computer, had been transformed over some unknown period. Strange old books lined the walls and the room felt unnaturally warm. When he looked at her, from his desk chair, with his legs spread wide and his shirt unbuttoned - as if he were lounging by the pool on a summer afternoon - she felt naked.

'You look great,' he said and she smiled reflexively, melting beneath the compliment. She made herself scarce after that but the words played in her mind all through the night. Her rational side insisted that it was a generic compliment, something he'd likely said to her before, but something deep inside her was **** to believed he'd meant it in the fullest sense. When she tried to recall the emotion on his face or behind his eyes, however, she realised that she'd spent the time in his room staring at his crotch.

More than a few guys tried to get in her pants that night and, one by one, her friends found places to crash for the night and get dicked down. She blew all of her suitors off, however. None of them could compare to the man she had waiting at home. She told herself she was being responsible but, as the party dragged on, she realised that she wanted, more than anything, to get back to him. She'd have it out with him, she reasoned, explain her feelings, no matter how difficult it would be. They'd have a mature conversation and figure everything out. Or maybe, just maybe ... he'd fuck her.

She drove home. The last time she'd been home so early was back when they were both in high school. 'Hey, sis,' he said, easily, as he settled down onto the living room couch, 'just about to watch a movie, if you want to join me.' Somehow, he'd known that she didn't have company. He also didn't seem curious about why she was home so early. A brief flicker of panic shot through, as she considered the possibility that he was aware of the thoughts and dreams she'd been having. Had she said his name a little too loudly once, in the shower or in her bedroom, whilst fingering herself?

'Sure,' she replied, hoping to mask her fear. She regretted her answer twenty minutes later. She'd always hated scary movies and she was **** to get close to her brother. He put his arm around her and the touch drove her crazy. She looked away from the screen as often as not and buried her face in his chest. He didn't comment on it but gently squeezed her a little from time to time.

When the film was over, he finally addressed it. 'Sorry, I didn't know you'd be back so early. Are you going to have trouble sleeping?'

'Yeah,' she said. Of course, the trouble sleeping wouldn't be on account of the scary move but the dreams she was likely to be plagued with.

'You could sleep in my bed, if you like,' he replied, as if it were the most normal thing in the world. He didn't even seem to wait for her to respond, instead wandering through to the kitchen to rinse a beer bottle.

This was her chance, she realised. The idea struck her hard and she felt herself getting wet, as she imagined grinding against him. Men had needs, needs she'd always been able to play on. If his dick got hard and she said as little as possible, maybe he'd let her satisfy them. 'I'd like that,' she said, 'yeah,' and she noticed a smile briefly spread across his face. In the minutes that followed, she grew giddy. It was almost impossible to hide her excitement from him as she entered his room, still strangely hot. She wore her favourite set of pyjamas but he wore only his boxers. They were tight and his bulge was unmistakable.

When she slipped under the covers, she couldn't help herself and she pressed her ass flush against his crotch. If he reacted negatively, she could brush it off but he gave no indication that he'd even noticed. Then, he draped his arm over her and pressed his chest against her back. 'Is this too weird?' he asked, making her feel guilty.

'No,' she lied, 'it's fine.' She dared not continue with her plan for the next few minutes. Eventually, however, she convinced herself that it would be much worse to try it whilst he was sleeping, so she started to move her ass up and down his crotch, as subtly as she could. He grunted but otherwise voiced no complaint and, then, it happened. She felt his member grow. Within seconds it was hard and erect and pressed between her cheeks. Her cunt grew wet and hot in response, as she began to grind her backside against him more confidently. When there was still no complaint from her brother, she knew that she had him. 'Do you like that?' she asked, feeling an urge to erase all doubt.

'Yeah,' he said, his voice strained, 'fuck yeah.' That was when he began to move in response, gripping her hip and grinding. She turned to face him and saw a ravenous hunger in his dark blue eyes. Then, they kissed and it was everything she'd ever wanted. She moaned into his mouth and reached for his cock, pulling it free from his boxers. That earned a gasp from him and he broke the kiss. Wasting no time, she crawled down and took him into her mouth. 'God,' he groaned as her lips brushed along his shaft. She sucked his cock long enough to earn a few more heavy groans but she didn't want him to come in her mouth. He protested when she removed herself, 'please, Stace,' but she rolled him onto his back and wriggled out of her bottoms.

'I want you,' she said, as she straddled him and slid herself onto his cock. She squealed in delight as all six inches slowly pushed their way inside. He groaned in response too and she tried to quicken her pace as soon as she could. From slow and steady sliding, to eager and wild bouncing in just a minute. With one hand on his washboard abs and another on his thigh, she rocked herself against him. Then, as the clock struck midnight, she came to her senses. 'Oh God,' she said, her voice uneven and shaky, as she stared at her brother in shock and disgust. As if she'd spent the past month in a daze, she realised all at once what she'd done.

'Stace,' he groaned, 'please, don't stop.'

Horror shot through her then. What had she done? She felt sick and tears began to roll down her cheeks. In her perverted lust, she'd betrayed her brother, seduced him in the cruellest way imaginable. Men had needs, she repeated her rationalisation to herself. 'I'm so sorry,' she said, sobbing, as she began to pull herself off. He stopped her, gripping her thigh firmly.

'I need this,' he pleaded. He needed to come. So did she, she knew, **** and sputtering when the realisation hit her. She'd already taken things too far, she reasoned. Would it make any real difference if they went all the way? In the end, he decided for her, thrusting himself into her. She let him but tried to look away as the pleasure surged through her body but when he placed one tender hand on her belly, slipping it beneath her top, she had to turn back. His touch was so warm and so gentle. As she cried, yelping in sick satisfaction with each buck of his hips, she drew herself down and cupped his face, kissing him despite herself. 'I love you,' he said and it almost broke her, 'I've been in love with you for years.

'They came hard, in perfect unison, and she slumped down, laying awkwardly on top of him as he held her. 'What've we done?' she asked, with a snotty nose.
