Cotton Crush has been trying and failing to suppress, or at least hide, his crush on his older sister Smitten Sweets. Worse still, he's moved across Equestria to live with her, his parent's attempt at making him clean up his act and get him on his feet as an adult. So when he finds himself home alone one afternoon, he can't help but indulge himself...

Written for my friend Flipside as a companion piece for her Subscribestar. Why not check her out as well?

Cotton Crush was not very good at appearing casual. No matter how much he tried to stroll around the house as if just wandering, he couldn't control the nervous flutter of his wings, or the way his eyes shifted nervously around every room. A small bead of sweat rolled down his brow as he went from the kitchen to the living room to the bathroom, but thankfully found no one else around. Not that he expected anyone - his sister, Smitten Sweets, had already told him she would be going shopping this afternoon, and wouldn't be back until dinner. But better safe than busted. Satisfied with his temporary solitude, Cotton made his way back down the hall, passing his own room up in favor of his older sister's, her naturally sweet scent still lingering in the air as he stepped in.

Smitten's room was a lot like its owner. Tidy and well kept, with plants in every available patch of sunlight against the walls. Fairy lights glowed softly in the afternoon light, strung up between posters of the romance novels she'd published and cascading over the pin board that hung over her desk. Even with the lights off, the room had a comfortable, almost magical glow to it, and a homey feel of controlled disarray. Her canopy bed took up the far corner of the room, blankets and sheets and pillows cascading off the edge from when she'd woken up this morning, as warm and inviting as the pegasus who slept in it. For a moment, he simply stood and basked in his sister's lingering aura, her room always one he felt comfortable being in even as a colt. It made what he'd come to do just a bit more embarrassing, though he'd long since pushed aside that feeling. He pushed the door until it was almost closed, then made his practiced way across the room to her dresser, eyes set on the bottom drawer. He'd learned long ago that this was where she kept her more intimate things, and had become well-acquainted with just how his sister might dress for a lover or even for herself. He nosed around in the drawer for a moment before pulling out a silky pair of panties, a pastel pink that would have fit nicely with her own coloring and was just sheer enough to drive his imagination wild.

Satisfied with his treasure, Cotton started to turn towards his sister's bed when his eyes fell once again on the pinboard over her desk. Dozens of happy faces looked back out from their captured images, his sister's friends from both Cloverly and from their hometown. One photo in particular had his attention though, a selfie she'd snapped of the two of them when he'd first come to live with her. They were sitting on the couch in the living room, and she had her hoof around his shoulders as they both smiled for the camera. Normally, Cotton was trying too hard to be cool to smile for anything, but Smitten had always been good at coaxing out his gentler side. He hesitated a moment before carefully pulling the picture from her pinboard.

Now satisfied, Cotton climbed into his sister's massive canopy bed, her familiar scent strongest as he snuggled down into the sheets. He lay there for a long moment, savoring the faux embrace with a long inhale. Buried amid the scents of fabric softener and his sister's usual scents, he could smell the sharp spice of her arousal, still fresh in the air. Warmth bloomed on his cheeks as he moved to better smell where she'd soaked the sheets this morning, that warmth slowly blossoming through his body as his desire for her swelled. He knew deep down how wrong it was to want his sister in this way, a perverse sort of love that his sneaking and snooping only dulled the edge of, but he couldn't help it. Without thinking, he let his tongue drag over the spot where her scent was strongest, wishing for all the world he could taste it from the source, that he was the one she was lusting after in the early morning hours. He rolled over onto his back as he lost himself in the fantasy, setting the photo of the two of them on a pillow near his head while his other hoof reached down to rub Smitten's pilfered panties over his swelling length.

He let out a long, shuddering sigh as he got into it, slowly gliding the soft fabric up and down his cock as he looked longingly at his beloved sister, imagining it were her grinding her way up and down his length. Her lips slowly kissing from his lips and down his neck as she murmured sweet nothings to him, teasing her panty-clad nethers against him until they were both soaked in her need. Of course, Smitten was too kind to leave him wanting long, though he knew she'd make him work for it. Giving him butterfly kisses as she got up to adjust her position over him, grinding her soaked crotch down into his muzzle while she put hoof and lip and tongue to work on his throbbing shaft. Cotton would pull those panties aside with his teeth, just like in her novels, dragging his tongue over her forbidden treasure at long last and drinking deep of her nectar. Their moans would fill the room as they took their time learning each other's bodies - that would make her the happiest, right?

His strokes grew faster as he imagined instead if Smitten would want him to take charge. If she were laying instead on the bed, doe-eyed and inviting, one hoof teasing herself as she beckoned him closer. She'd turn and offer herself to him, flank raised high to meet him as he took his place over her, mewling sweetly for him to claim her at last. Just like the prince and princess in her last novel, she'd sing his praises as he sank into her for the first time. They;d start slow at first, but quickly lose themselves to the passion, shaking the bed until its legs threatened to buckle as she cried out for more and more. The sound of his hoof quickly stroking up and down his drooling cock filled out the sounds of his fantasy just enough, sticky pre soaking his sister's stolen panties as well as his belly as he sank into the pleasure. His eyes fluttered open to look again at their picture, and something else caught his eye, haphazardly tucked under one of the pillows around him. It couldn't be...?

He reached out with his free hoof to push the pillow aside, revealing a vibrating wand. Smitten must have been using it this morning, and forgotten to put it away. Cotton reached out and brought the head of it to his muzzle, his sister's lust hitting him like a truck as he eagerly licked the toy for any hint of her nectar left behind. Another of her novels crossed his mind as he hesitantly turned the toy on, the sound of its buzzing quickly filling the room. He pressed the head of it just under the flared head of his cock, shuddering as the new sensation almost overwhelmed him with pleasure. Maybe Smitten would use her toys on him like this as well. Perhaps her sweet countenance didn't extend to the bedroom, and she'd rather tease and torment him before he'd be allowed to take her. Keeping him prone on the bed, legs spread wide as she slowly worked her favorite wand up and down his aching length, watching with fascination as pre oozed like a river from his overstimulated body. He moved the wand in time with his fantasized sister's desires, low moans escaping his muzzle as she imagined what else she might have in her toybox, what else she might do with him helpless under her control. Unbidden, an image of her wearing a strap-on came to mind, a faux cock of her own hanging lubed and ready between her legs. She'd give him no chance to protest as she mounted him like the good little brother he was, slowly pushing the molded shaft into his waiting rump. A blush spread across his face as the thought drove him over the edge, and he held the wand tight against his cock as the first ropes of spunk hit his chin, another shot arcing over his shoulder to land squarely in the sheets. His other hoof stroked frenziedly, trying to prolong the heady climax when-

"Cotton? I'm home!"

Fuck.

The horny pegasus scrambled as he heard his sister from down the hall, cock still spurting mess all over the sheets as he tried to compose himself. He swore under his breath, unable to do anything but try and pull the sheets off the bed, trying to at least contain his mess to the bundle of soiled cloth.

"H-hey! I'll be right there, I'm just grabbing your sheets for the wash!" He hoped his voice didn't sound too shaky as he scrambled to turn the wand off and return it to its hiding spot, straining to hear if his sister were coming down the hall to check on him. Holding the bundled mess against his crotch to try and preserve his modesty, he scrambled out the door and towards the laundry room at the end of the hall, just as he heard the sound of hooves coming up behind him.

Once again, Cotton tried and failed to look casual as he loaded the soiled sheets into the wash, following them up with whatever dirty laundry he could find in the baskets. Thank Celestia that he'd all but slipped back into his sheathe before Smitten popped her head in the door to greet him properly, though he could still feel himself sweating bullets.

"Oh, there you are! Thanks for that, I was meaning to start a load myself." She trotted in and gave his forehead a quick kiss. "You're always so helpful around the house, Cotton. Do you think I could bother you to help me bring the groceries in when you're done?"

"Oh, uh. Yeah, sure thing!" She'd hardly left the room again before he slumped down over the washing machine, sighing with relief that he'd gotten away more or less cleanly. He took a moment to compose himself before starting the laundry machine and making his way back down the hall to help as Smitten had asked. He gave no thought to what had become of the panties he'd cum all over, figuring he'd managed to bundle them up with the sheets. And certainly Smitten wouldn't say later that she'd found them, laying discarded near the photo he'd left in her bed. Absolutely scot free, for sure.

Right?
