Soldier Sister Stalker Spouse

Twilight and her brother lay wrapped in each other's warm, cozy hooves. They panted together, conversing through gentle squeezes, loving looks and breathy whispers. The siblings nuzzled and smiled and cuddled and giggled, like a pair of excited foals who had just discovered how great kissing could be. She rubbed her horn against his, a symbol of their trust and intimacy, while he gently stroked her mane. So long as they were together their troubles seemed far far away.

Cadence trotted gaily into the room, singing to herself. “Shining and Twilight sitting in a tree, do-ing what they shouldn't be~”

Shining Armor sat bolt upright and hugged Twilight like she was a stuffed animal. They each watched Cadence with the wide, fearful eyes of naughty children that have been caught in the act.

“~Starts with S, ends with X, oh dear Celestia it must be sex!~” Cadence stopped and winked at them. “Shining, you should have told me we were expecting guests. I would have hurried back.” Seeing their blank looks, she sighed and shook her head. “You've managed to make quite a mess without me.”

Shining followed her gaze down to his sister's crotch. Calling it a cream pie would be an understatement. He cleared his throat. “This is exactly what it looks like,” he said, leaning forwards slightly to put himself between Twilight and Cadence. “I talked her into it, it's all my—“

“Oh don't worry about that,” Cadence interrupted. “You can't keep your feelings hidden from me. Love is my special talent and it was the love you two share that attracted me to you in the first place, my dear Shining Armor. I can hardly be mad now can I?”

“Err...”

Twilight frowned. This wasn't exactly how she'd imagined things would go. “Were you watching us?”

Cadence nodded. “You were enjoying yourselves so much that I could hear you from the other side of the house. It sounded like you were having fun so I didn't want to interrupt.” She glanced disdainfully at where Twilight was leaking onto the bed. “Honestly Shining, if you want to do this sort of thing you need to rein in your... exuberance a little.”

Shining nodded wordlessly. This was all turning into a very surreal dream.

Twilight bristled, feeling embarrassed that Cadence had called her loud. “Hey, you can't just order my brother around like that!”

“Uh, Twilie, I think—“

“Quiet!” she snapped.

Cadence smiled and her tail swished back and forth as she approached the bed. “Twilight, I'm happy for the two of you to have fun together but...” To Twilight and Shining's astonishment, Cadence lowered her head and licked a sticky white glob off the covers. “You've got to learn to share.” She darted forward and kissed Twilight deeply. The young unicorn's eyes widened in surprise as Cadence demonstrated her point, but, gradually, Twilight's eyes slid shut and she became caught up in the moment.

Cadence certainly didn't seem to be in any hurry, and Shining Armor's jaw dropped lower and lower as each minute melted into the next. He could of watched them all day, but eventually the princess broke their kiss, leaving a single translucent strand connecting her to Twilight's outstretched tongue. “See,” said Cadence, “sharing is fun.”

Twilight swayed, her eyes half-open. “B-but Princess... why...”

Cadence laughed softly and kissed the tip of her horn, sending an electric thrill down the young mare's spine. “I told you before, Twilight, you're anything but a regular old unicorn, and I've watched you grow into a very beautiful pony.” She looked over at Shining Armor, who was losing the battle to hide his decency behind a pillow. “Your brother isn't too bad either.” Cadence nibbled Twilight's ear and whispered: “But now I have to clean up the mess he's made.”

Still feeling dazed, Twilight just nodded and watched with bemusement as Cadence followed the sticky white trail that led from the bed to between her legs. A nudge from the princess pushed her over, and she found herself lying on her back looking up at the ceiling. Cadence gently held one of Twilight's legs and kissed the tip of her hooves. Twilight giggled, she was quite ticklish there, and more giggles came as Cadence kissed all along her calves, her haunches, her thighs... all the way down to her—

Twilight gasped as the princess's lips reached her most intimate of places. She felt Cadence's tongue slipping inside, licking every inch of her supple pink marehood. Twilight had never felt the touch of a mare like this before and, although she loved her brother dearly, she had to admit that Cadence was far better at this than he was. She let out a groan as Cadence probed deeper, her pleasure growing with each passing second.

Shining Armor was mesmerized. The two mares he loved more than anything in the world were entwined on the bed. There was his little sister, her head thrown back in ecstasy and her eyes clenched shut, biting her lip to keep from screaming as his wife ate her out. It was enough to drive any stallion wild.

Cadence lapped up the sticky cocktail between Twilight's legs, relishing how the little unicorn's own juices mixed with those of her brother. She left no nook untouched and no cranny unexplored but still she didn't get enough. Cadence clamped her mouth over Twilight's pussy and sucked as hard as she could.

On the bed, Twilight twisted and squirmed, arching her back as the fresh sensation flooded through her body. She gasped and cried and feebly clutched at the sheets, each pulse carrying her to greater and greater heights. She couldn't believe the princess was so good at this.

Cadence swallowed another mouthful and pulled away. She looked over Twilight's panting body and let her gaze linger on the pretty pink sliver of flesh between Twilight's hips which quivered with the mare's every breath. She'd cleaned up most of the mess but Twilight was moving around too much for her to do things properly. She needed some help.

Shining Armor's pillow flew out of his grasp and he looked down at his stallionhood in surprise, half believing that his passion had become so inflamed that it had managed to catapult its cushiony restraint across the room. Cadence rolled her eyes and motioned with her glowing horn. He quickly realized his mistake.

“Shining dear, please come here and lend your sister a hoof.”

Shining did as he was told and sat down behind Twilight. He lifted her into a sitting position and held her gently. Twilight melted in his lap and rubbed her cheek against his chest, basking in his comforting scent. She wriggled happily as she felt his hardness pressing into her back and turned to kiss him as he leaned over her shoulder. But the princess hadn't quite finished yet.

Cadence surrounded Twilight with her magic and floated her into the air just above her brother's lap. “I'll just be a minute dear,” she told Shining, and then disappeared beneath his sister.

Shining Armor couldn't see exactly what was going on, but by the sounds Twilight was making Cadence must have been doing something wonderful to her. He could smell his sister's arousal, the air was thick with it, and it only served to amplify his own throbbing desire. He didn't have to wait long.

Cadence sat up and licked her lips. “Hmm, I think you're ready now, Twilight. Just try to relax.” She let the young mare descend gently while guiding her husband's stallionhood with magic.

Twilight's decent came to a halt and her eyes flew open. She felt pressure against her asshole, which still tingled from Cadence's teasing a moment ago. “W-wait! I've never done this before!”

“You'll be fine, Twilight. You've always been a fast learner,” said Cadence, lowering Twilight slowly.

The pressure grew and grew until, with a sharp intake of breath, Twilight was impaled on her brother's erection. Just his tip was inside but her ass had already given up all pretense of resistance and swallowed the rest of his length hungrily. Her body went rigid as she concentrated on the weird sensation. Twilight felt as if she was being stuffed and she wasn't sure if she liked it. But Shining's warm breath tickled the back of her neck, he was right there with her, and somehow the very thought of what they were doing made it feel so much better. By the time her brother was buried to the hilt, Twilight was loving every minute.

Cadence chuckled. “My my, I think she likes it. How about you, dear? Are you having fun?”

Shining Armor nodded. Twilight's ass was hot and tight and she clenched and squeezed like she was trying to wring him dry. He rocked his hips gently, a slight motion in and out that wouldn't disturb her seat on his lap.

Grinning, Cadence spread Twilight's legs and leaned down to continue where she'd left off. Twilight squeaked but with her brother to keep her steady she didn't wriggle and fidget like she had before. Cadence was now free to thoroughly explore all of the young mare's hard to reach places and she was fully prepared to make the most of it. She spent long minutes caressing Twilight's soft sensitive marehood, running her tongue along the twitching silken interior and teasing Twilight's g-spot as she went. She heard a muffled, joyous sound and looked up to see the siblings kissing passionately over Twilight's shoulder. Cadence smiled, they looked so sweet together, and she turned her attention back to the little unicorn's sex to prepare for the grand finale.

Twilight tried to groan but her mouth was occupied. Cadence's lips teased her clitoris out of hiding and proceeded to kiss and lick and suck and flick until Twilight trembled all over. She went limp in Shining's hooves, only stirring to answer his tongue with her own. She could feel him deep inside of her, sending hot waves of pleasure racing up her spine.

Just one more push, Cadence thought to herself, before delicately taking Twilight's clitoris between her teeth. As if a button had been pressed, the little pony's legs quivered and shook. Cadence watched Twilight being consumed by ecstasy and the princess's wings unfurled all on their own. Shining was right, she did look adorable.

Shining held his sister close as she came. She shuddered with the orgasm and, deep inside of her, Shining acutely felt her every movement. With the fresh sensation pulsing through her body, Twilight's muscles squeezed and relaxed and clenched and released in rapid succession until Shining Armor was so close that he couldn't hold himself back any longer. He thrust his hips, bouncing Twilight up and down in his lap as he vigorously pounded her ass. He came a few moments later, pumping into her several more times before relaxing, satisfied, on the bed. Twilight lay panting on his chest, still experiencing twinges of pleasure and a delightful hot sticky fullness from her behind.

Cadence reclined on the bed next to them and Shining rolled onto his side, dropping Twilight between himself and his wife. The two mares curled up together and kissed while Shining pulled out of his sister with a 'pop'. He watched for a minute or two then sat up and stretched. “I'm going to take a shower. Play nice you two.”

Shining Armor smiled to himself beneath a cascade of hot water. This night had turned out much better than he expected. Ever since his marriage he'd been worried about Twilight feeling jealous but now she and Cadence were getting along very well indeed. Shining chuckled; knowing Cadence she might have planned this from the start.

He shook out his mane and looked around, thinking back to his first post in the royal guard. A shower this size would have used by a whole squad at once and there'd only be five minutes of hot water between all the recruits before it ran cold as ice. Shining had never known a better incentive for getting up early in the morning. Now he could have all the hot water he'd ever wished for and a shower so big that he could barely see the other side through the steam. And this was just their house in Canterlot. Being married to a princess certainly had its benefits.

He finished rubbing himself down with soap and sponge just in time to hear the sound of somepony joining him. Shining turned around and smiled at his sister. “I can use the bathroom by myself you know.”

Twilight kissed his cheek. “Somepony has to make sure you don't get lost down the drain.”

Shining Armor made a show of putting his hoof over the drain cover. “Look, I don't fit.”

She seemed unimpressed. “Did you wash behind your ears?”

He nodded.

“What about your hard to reach bits?”

“Clean as a whistle.”

“In that case,” said Twilight, kissing her way down his neck. “You deserve a reward... Sit down.” Her brother did as she asked and sat down on a rubber shower mat that covered part of the floor. Twilight leaned forward and nuzzled his crotch, coaxing and goading until she could seize him between her lips. She was keen to continue what she'd starting earlier that night.

Shining sighed as his sister's tongue worked its magic and he watched her head bob up and down. Her long wet mane looked more beautiful than ever and she was making him feel so good that he, too, was filled with the desire to share.

To Twilight's surprise, Shining lifted her with his magic and rotated her into a better position. He held up her hindquarters with his forehooves while the rest of her dangled upside down. Now he would have no problem returning the favor.

Twilight's cheeks flushed red. Despite everything they'd done together and the fact that she was currently sucking him off, she still felt embarrassed to be seen like this. She was completely exposed, a fact Shining made abundantly clear by licking her rear end from top to bottom. Her asshole, still sensitive from before, quivered under his touch. It gave him an idea.

With a small nudge of telekinesis, Shining directed the shower at his sister, causing Twilight to wriggle and squirm as the warm torrent of water tickled her backside. He felt Twilight groan, her whole mouth vibrating around his stallionhood.

Twilight tried to focus on what she was doing but her mind was scattered and fuzzy. Although her brother lacked Cadence's technique he made up for it with enthusiasm. He flicked his tongue over her clitoris before sliding deep into her pussy. Her back legs, hanging limp, spasmed once or twice before he slid out again, giving a moment's reprieve before he started over. And all the while she could feel the shower's spray on her ass; a weird, wonderful sensation that underlined the pleasure welling up inside her. Too distracted to do anything fancy she simply sucked him as hard as she could.

Shining let out a grunt, surprised by his sister's forcefulness. Her usual subtle teasing had vanished... not that he was complaining. Shining focused on the delectable banquet in front of him. He licked her like he was licking cream off a sundae, paying extra attention to the cherry on top, although from his perspective her cherry was actually lower down... and much more delicious.

Twilight came first, succumbing to her brother's affection and the relentless sensation of falling water. The two combined into a pulse of pleasure that pounded through her body. Her rear legs kicked the air feebly and she groaned long and low, which Shining Armor felt most intimately from inside her mouth. It was enough to tip him over the edge as well. Twilight had to swallow several mouthfuls so she wouldn't spill. She found it the perfect accompaniment to the ecstasy she experienced and she massaged him with her tongue until she was sure she had gotten every last drop.

In the hot, steam-filled bathroom Twilight Sparkle and Shining Armor lay together on a pile of fluffy white towels. Twilight nuzzled his neck. “I love you Big Brother.”

He kissed her on the nose. “I love you too, Twilight.”
