Soldier Sister Stalker Spouse

Shining Armor began to doze. His visit to Canterlot had been full of long boring meetings, and now the warm night air was making it hard to sleep. He'd thrown open the windows and replaced the duvet with a thin, airy sheet but peaceful slumber still eluded him. The empty space in the bed beside him didn't help either. Cadence was having her own meetings with the royal sisters and had said she'd be back very late that night.

He was wondering whether he should try counting sheep again when he became aware of a mound crawling under the covers beside him. Shining was impressed; he hadn't even noticed his wife coming in. Cadence must have gotten off early and was being extra quiet to surprise him. Shining kept his eyes closed so he wouldn't spoil her game.

Her warm breath tickled his crotch and he realized what she was actually planning to do down there. Shining Armor raised his eyes in a silent prayer, thanking Celestia for what he was about to receive. A blow job was just what he needed after such a long day, and, beneath the covers, Cadence seemed almost hungry to provide.

Shining grunted; she'd gotten better. Cadence was no where near as standoffish as she had been the last few times. Her tongue massaged his member while she sucked him firmly with each rhythmic bob of her head. It felt great, just like when— he stopped himself there. A suspicion had taken root in his mind. The way she let go only to suck him in again. The way she held the head of his stallionhood between her lips and swirled her tongue around the tip. It was all too familiar... and wasn't the mound a bit small?

He lifted the sheets and stared for a moment before putting them back. Shining looked around the room to make sure that nopony else had materialized in his bedchamber and then threw back the covers. It hadn't been his imagination.

“Twilie? What are you doing here?” But what she was doing was plain to see so he tried a different question. “Why are you here?”

Twilight looked up at him with her big purple eyes and slowly released her prize. It was rude to talk with your mouth full after all. “I heard you were in Canterlot for a few days and that put you within my reach. I'm here to see you of course. I missed this. I missed you.”

“But it's been so long since we... I mean, I can't,” he said, trying to ignore the little voice that told him to let her finish. “I'm married now.”

“I don't care,” said Twilight and she gave him a kiss so vigorous that Shining didn't care either. “And I remember you promising to marry me years ago.”

“Oh come on we were just kids! It's not like we meant it.”

“Didn't mean it?” She leaned in close until their muzzles were almost touching. “You said you loved me. Did you mean that?”

“Well of course I love you—“

“It's just that now you have a princess I'm not good enough for you anymore.” She held his gaze briefly then turned away.

“Don't be like that.” He lifted her chin gently so he could look into her eyes. “You're the most brilliant, most beautiful, and most talented sister I could ever ask for. I couldn't love you more if I tried.” He leaned in to give her a quick kiss on the cheek but Twilight wrapped her hooves around his neck and found his mouth with her own.

It was several minutes before Twilight lessened her grip and allowed her brother to go free. She really did miss me, he thought to himself. Shining saw his sister's hopeful expression and his resistance melted away. He was falling into a trap with a sexy lure and he couldn't stop. He didn't want to stop. He wanted her to be happy. “I never could say no to you, Twilie,” he said, smiling. “I missed this too.”

Twilight grinned and kissed him again but she still sensed some hesitation on his part. “What's wrong?”

“I'm worried about Cadence,” said Shining Armor, although in present company he was reluctant to admit it.

“Don't be. Cadence always used to go on about sharing... and besides,” Twilight said, her smile widening as she stroked his chest. “You were mine first.” Her brother simply nodded, knowing his place.

“Lie back and relax. I've been looking forward to this.” Twilight straddled her brother's hips and shifted forward, sandwiching his erection beneath her pussy and leaving him slick with her excitement. With her forehooves resting on his chest for support, Twilight sat upright and slid down his length slowly, scratching an itch that nothing else could satisfy. “Do you remember how we used to play in the bath together?”

He chuckled. “I miss those days of innocence. You would get so upset if I didn't let you get in with me.”

Twilight pouted and started to grind herself on his member. “I was just worried that you'd be sucked down the drain when you took the plug out.”

Shining Armor grunted. Twilight's activities were making it hard to concentrate. “Sure you were. What about the time in college when you messed up your potion mix and accidentally put yourself into heat?”

“I didn't mess up that potion,” she said matter-of-factly. “I just made it a bit too strong, that's all.” Twilight leaned forward and give him a long, lingering kiss. “Luckily my knight in Shining Armor came to the rescue.”

“You could have told me what it was before you made me drink it too." Shining tried to look cross but his sister's smoldering eyes made it impossible. "I swear I didn't walk right for a week, and I'm still not convinced what you got me to do actually helped.”

“No...” Twilight said coyly, “But it was a lot of fun.”

“You've got a perverted mind, you know that?”

She leaned in close and nibbled his ear. “Says the captain of the guard who wants to screw his own sister.” Twilight lowered her body and angled herself so she could rub her clitoris on the head of his penis. “I can feel it... the strength of your desire. You're holding yourself back. You don't have to. Just let yourself go.”

“Heh, I guess we're both messed up then. I'm enjoying this too much.”

Twilight closed her eyes and bit her lip, grinding herself against him even harder. “I know you want to do it. Go on. Sweep me off my hooves. Fuck me until I squeal. Fuck me until I squirm.”

“The way you're going I won't be able to stop until you beg for mercy.”

She giggled, feeling in control. “I'd like to see you try. I'm on top, Big Brother.”

With a twist of his body and a flurry of hooves, their position was reversed. It was a simple movement for such a trained fighter. “As captain of the guard I have a trick or two up my sleeve,” he said, enjoying the mixture of surprise, admiration and embarrassment in his sister's eyes.

On her back, Twilight's face burned red. She'd landed with her legs spread eagle, presenting herself a little more than she'd intended. Her pulse quickened as Shining stood over her, ready to accept the invitation. She felt his erection pressing against her marehood and had to bite her lip even harder than before as he increased the pressure, stopping just on the cusp of penetration.

“Twilie, have you already cast that spell of yours?”

“Yes,” she replied, more hastily than she'd meant to. “I'm safe... and you won't hurt me even if you wanted to.” Her body quivered with anticipation and he nudged her in response, parting her moistened lips ever so slightly. “Please don't tease me like this, I can't bear it.”

“Your wish is my command,” said Shining Armor, and he thrust himself into her with so much force that for a moment she was lifted off the bed. Twilight gave a stifled cry, as caught off guard by his suddenness and savagery as the burst of pleasure it had caused. Her voice broke into a low moan as he withdrew slowly, inch by inch, his glans hitting her in all the right spots.

Twilight clenched tightly as he was about to leave, her body not wanting to let go. But Shining had never intended to simply abandon his sister, and he kissed her gently to assuage her fear. He waited until she relaxed before thrusting again.

Twilight shook with the impact and buried her face in her brother's neck to try and muffle her own embarrassing squeaks. She could feel him deep inside, filling her perfectly, like they were made for each other. This was the feeling she remembered. The feeling she had yearned for.

“Ohhh, yesss... just like that...”

Shining Armor smiled as they made love, and soon his sister's prophesy came true and she arched her back and squirmed beneath him, trembling on the point of orgasm. But the release she craved was denied to her as Shining pulled out even more slowly than before, being careful not to tip her over the edge. He planted little kisses on her chest and stomach, happy to take his time.

“Don't leave me like this. P-please,” she whimpered.

After what Twilight felt was an eternity, her brother slammed home. A shock wave of pleasure exploded inside her. She wrapped her legs around his thighs, dug her hooves into his back and raised her head to the sky to cry out in triumph. But this last was cut short as Shining kissed her hard on the lips, bearing her back down onto the pillows.

They kissed ravenously, like two starving ponies fighting over a cherry. Neither paused for breath, their bodies pressed so close together that Shining Armor could feel every twitch and shudder of his beloved sister's orgasm. He kept his hips moving gently, prolonging Twilight's ecstasy until the young mare felt like she was melting away.

Twilight relaxed on the bed, basking in post-coital bliss. She was dripping with sweat and her mane was a mess but it had been so worth it. Her most base and primal urges had been satisfied and it left her whole body tingling wonderfully. She closed her eyes to better enjoy the moment and sighed with happiness, unable remember the last time she had felt so utterly content.

Shining Armor nuzzled his sister tenderly. “You make the most adorable face when you come.”

“Sh-shut up!” said Twilight, her cheeks glowing red. “You're not supposed to say things like that, it's embarrassing.”

“I can't help it if you look that cute.” Shining leaned down and kissed her on the nose. “I hope you're ready to show me again.”

She kissed him back and wriggled her hind quarters in anticipation. “And again and again... until I beg you to stop. Isn't that what you promised?”

Shining gave her a sheepish grin. “Well, I might have been boasting a little there,” he admitted, “but I'll see what I can do.”

Twilight all but purred as her brother slipped back inside. Her previous rapture had left her sensitive and his every move sent a jolt of pleasure running up her spine. She hugged his neck tightly, but as she gazed over his shoulder, a flickering shadow made her whole body freeze.

Shining Armor paused as his lover tensed up. “Is there something wrong?”

Twilight could have sworn she'd seen movement, but no matter how hard she stared at the doorway she saw only darkness. “I thought... no, it's nothing. Don't stop.” Her brother shrugged and resumed his slow deliberate rhythm, much to Twilight's delight.

The prospect of being caught gave Twilight goose bumps and her mind quickly turned to mischief. What if they were being watched? What if it was Cadence? Twilight imagined the look on the princess's face as she watched her husband making love to his sister. She liked Cadence, but this was her brother. She felt a thrill of excitement and the thought only served to amplify her pleasure. Twilight groaned out loud, she couldn't stop herself, and this too gained a new significance in her fantasy. Cadence would hear it and turn green with envy. She'd make herself known and demand that they stop, but Shining would ignore his wife's protests and, at Twilight's instance, pound his little sister even harder. And then they would run away together and...

“Ah! Yes, yes!” Twilight cried out, making no attempt to hide her pleasure.

The second climax swept through her much like the first but this time Shining Armor didn't stop, or even slow. He kept going, causing his sister to squeak and squeal as she was allowed no respite from the sensation. Twilight's bewitching moans wore away at her brother's self control and he began to pump his hips faster and harder, seeking his own gratification.

She wasn't ready. Twilight hadn't even begun to recover before she exploded again. It was too much too soon. The pulses of her third orgasm shook her body and left her speechless. Twilight found it hard to think, the sheer force of it clouded her mind. She acted on instinct.

Shining Armor was moments away himself, but as he tried to pull out his sister wrapped her legs around him tightly and refused to let go. “Twilie? What are you doing, I'm about to—“

Twilight relaxed her grip just enough to let him thrust his hips as he pumped her full of his seed. Thick and warm, her brother's love filled her to bursting and Twilight felt closer to him than ever before. She kissed his neck and wished that this moment would never end.

With his hot, tired breath tickling her horn, Twilight smiled and nuzzled her brother's cheek. “You make the most adorable face when you come,” she whispered.

From the shadows of the corridor, Cadence watched the two lovers tenderly. Best give them another few minutes, she decided.
