He never thought it would get this serious. Can he really keep it a secret? Or will it get too out of hoof for him to handle?

Shining never thought much about the effect his actions had on others. Everything was fine until he started to notice the looks other mares gave him. Giving into pure lust and desire was great at first, until some ponies started to fall for him.

He tried to ignore it all when he married Cadance, but there are some things you just can't run away from.

And sex between multiple ponies

Curiosity

Shining Armor just got home from a long day. He had been away training to be part of the royal guard and had returned for a short vacation. Having been tired and tense he trotted into the room he still shared with his little sister. His parents had just gone out for the night and she was already asleep. He hopped on to his bed pulling out a magazine of mares revealing themselves in scandalous ways. Using one hoof he gently started to stroke himself. His shaft grew until it was fully erect. Using his magic he opened a box hidden under his bed and took out a bottle. He squeezed out a clear gel and started stroking faster as he spread it over his cock.

Twilight shifted in her bed quietly. Blinking a few times from under her sheets. It was dark but she could tell it was her brother on the bed across from her. She was about to greet him when she saw his hoof moving. She had never seen him like this before he left. His breathing was hard, his horn was glowing bright and he was grunting as he stroked faster. All of a sudden the stroking stopped as he convulsed and a white substance came out.

Shining panted and cleaned the mess up. It was still too early for them to come home and he wasn't satisfied yet. He turned a few pages till he found a mare he liked and began the process again. Unaware of his sister watching he got more lube and started moaning louder as he stroked himself.

Still watching and confused Twilight stayed quiet as she felt a strange heat growing between her thighs. Subconsciously she started rubbing her legs together as she watched. The feelings increased and soon she was lightly panting along with him. This time when he came she had her own silent orgasm. The feeling was overwhelming and tired her out, so when he checked to make sure he hadn't woken her up she was passed out.

For the rest of his time home, every night that he would stroke himself Twilight couldn't help but watch and do the same. Eventually she got to doing it on her own. The last night he was there he went out with some friends and had a few drinks. When he got home he was still a bit buzzed from all the shots he took. He trotted quietly past his parents room to the bathroom, hoping a hot shower might do him some good.
After he got out he heard light whimpers coming from the room he shared with his sister. "Twily?" He peaked through the door to see her rubbing herself. Slowly he started to get an erection. He kept watching until he heard her moan.

Twilight whimpered as she drew close to her orgasm. "Big Brother." She moaned his name, unaware of his presence. She called his name out a final time as she reached her orgasm. Panting she started to relax until she heard the door open. "Shining!" She squeaked and tried to cover herself fast, embarrassed at her actions.

"Its okay Twily. Its just me." He looked down at her body. She was small and still had just begun to blossom, but he couldn't help staring at the juices flowing out of her. "Look, you made a mess. Here," he pulled her to the edge of the bed and brought is mouth between her legs.

Scared she protested at first. After feeling his hot breath on her lower region she settled down. "Brother?" Twilight questioned as he started to lap up her juices. "Brother... What are you...d-doing?"

Shining looked up at her as she moaned. "Want to feel really good Twily?" He stopped licking to look her in the eyes. She nodded nervously as he pushed her lightly on her back. He carefully positioned himself over her and placed his shaft at her entrance. Slowly he started rubbing his shift against her wet folds. "Oh Twily, you're so wet already." He panted as he continued to grind against her. "Want more?" He looked down, the lust over coming him.

Twilight stared up at her brother. She could barely speak through her moans. "Y-yes. P-please!" Her body wanted more, but she didn't know what exactly it needed. All of a sudden the grinding stopped making her pout. "Big Brother why-"

Leaning down he kissed her gently. He placed his cock at her entrance hesitantly prodding her. He kept this action up until she started bucking her hips instinctively. Only the head of his cock had entered her so it wasn't too late yet. "Twilight I-" He stifled a moan as she bucked her hips some more. The pressure was almost too much for him. He pulled back and started sliding his shaft through her folds once more. "Twilight, want to make your brother happy?"

Looking up at him she nodded through her panting. He had her open her mouth and start sucking his tip as he grinded his base against her. She opened wide and welcomed the intrusion. It was hard and soft at the same time. She began sucking and licking. Her moans were muffled by his thrusting into her mouth.

Once she orgasmed one final time Shining started to thrust more. At his peak he pulled out of her mouth and began stroking himself faster. "Twilight, want to taste your brother's cum?" He knew she would agree even though she didn't know what he meant. He moaned as he pumped faster. "Open wide." He instructed then blew a load all over her. Shining watched as she swallowed what got in her mouth.

He knew it was wrong. She was his little sister and yet... Her body was all he could think about on his way back to Canterlot. "No... It can't happen ever again. Not with her."

The Mare Before Cadance

"Oh this place is just gorgeous! Its too bad I didn't get to see it with a nice stallion." A white unicorn mare trotted gracefully around the halls where the gala had been held just a few nights before. She was there partly to see it for what it was and partly for business. While looking at the tapestries she bumped into somepony. "Oh my! I'm terribly sorry!"

The stallion was one of the royal guards. He used his magic to take his helmet off and bowed before her. "Excuse me Mrs?" He looked at her confused. "I'm sorry, but what is your name?" He couldn't help but stare into her beautiful blue eyes.

The mare blushed and offered a hoof. "The name is Rarity, darling... And I'm not married." She batted her eyes at him making him flustered. "What about you?" She inquired almost seductively.

The stallion almost fell for her completely right then and there. He straightened himself out and cleared his throat. "I'm Shining Armor of the royal guard. I'm also... You know... Not seeing anyone..." He took her soft hoof into his and placed a light kiss on it. Seeing the smile on her face when he did that gave him some relief. "So, Rarity, if you're not too busy after would you like to go out? I could maybe show you around Canterlot if you like?"

"I think I would like that a lot, Shining. I'll see you in the gardens at seven." She blushed and curtsied him before trotting along.

It didn't take long before the two started dating. They wanted to take things slow at first, but eventually the tension got to them. It had been several months now and he had started staying at her place when her friends and family weren't around.

Rarity woke up, her hair a mess and entangled in sheets. Using her magic she fixed both as she moved quietly in her room, not wanting to wake her guest. As she walked over to her tub, filling it with water, she felt hooves starting to wrap around her waste. The weight pushed her just a bit over the edge, but instead of her usual gasp she moaned at the sensation between her legs. "Well somepony is rather... Excited this morning." She giggled and moaned as the feeling continued.

Shining Armor kissed her neck as he rubbed his shaft between her folds and against her clit. "I can't help it if the first thing I see when I wake up is your sexy rump." He groaned quietly in her ear as he pulled back and positioned himself at her entrance.

Rarity moaned as he prodded her, sliding his tip up and down her folds then circling her clit. "Wait what about... The c-condom... Ahh... So... G-good..." She couldn't help but moan and pant as he teased her. The longer he teased the more she wanted him in her. "Sh-shining! I'm gonna-!" She clung to the rim of the tub as he rubbed her clit, sending her over the edge.

Feeling her orgasm on his shaft he couldn't take it any longer either. He slid back to her entrance and slipped the head in easily. He started slowly taking it out and thrusting in just a little more each time until he was almost half way in. Out of nowhere she backed into him, forcing him all the way in. He chuckled as he started thrusting deeper and faster into her. "Somepony's needy. You're so tight you just keep sucking me back in."

She blushed hard trying to ignore his comment. "I'm not doing a thing! You're the one slamming into me and... Ahhh... Throbbing with need deep inside me... Mmm..." Rarity could feel herself getting close and used her magic to massage his sack as he thrusted.

Tilting his head back a little he began thrusting harder. "Rarity! If you don't stop I'm gonna-" Shining didn't finish his sentence as he felt her walls wrap around his shaft tightly in a powerful orgasm. He tried to pull out, but she stumbled back sending him deeper into her. That's all he needed to lose control. He came hard deep inside of her. He slouched over her a bit panting hard. "That felt great." He Nuzzled her, still buried deep inside. "I love you."

Things didn't stay great for long. Their jobs made it hard to see each other so they eventually agreed to split and go their separate ways. It was easier without anypony else knowing about them. There was no drama and nopony to put in their opinions about being better off this way. They knew they would move on, but until they did it was going to hurt a lot for them.

The Knight's Dreamy Rebound

It had been three weeks since their break up and Shining was stuck in a slum. His work was lacking and his attitude had changed immensely. Everypony had noticed, including Celestia and Luna. Being their most prized guard they felt it their responsibility to do something about it. After talking it over they decided on how to go about things.

After his shift was over Shining trotted off to his quarters where he found a note left for him. "What's this?" He used his magic to bring it closer and began to read it.

Dear Shining Armor,

Please come to the back of the castle after your shift. You will find a fountain surrounded by rose bushes.
There will be a gift for you waiting there with more instructions. Make sure you're alone. What is there is
for your eyes only and the gift is yours to use only as well.

With care,
Anonymous

Shining was baffled by this and questioned whether or not to go. Ultimately he made the choice to at least check it out. He couldn't recall there being such a fountain before, but after a bit of a walk there it was. Just as the letter had said, there was a fountain surrounded by rose bushes. Carefully he trotted over to investigate. "Hello? Is anypony here?" He looked around only to find he was alone.

At a second glance he noticed something was off. In the fountain was a tiny bottle. Using his magic he took it out. Inside he could see a paper and a pill. Uncapping the bottle a puff of smoke came out and spread over the water. He watched as it changed color before making the fountain drain and open up into a spiraling staircase. He then read the letter that told him to go down the steps, so he did. Halfway down he started to smell something sweet. "Hm? This smells like..." He breathed in deeper before the sleeping powder knocked him out.

"Sooo gooood...." A mare moaned waking up her sleeping guest.

Taking a few moments, Shining started getting his senses back. He blinked his eyes a couple times, the blue blur becoming clearer. His sense of feeling was also coming back. He could feel his erection throbbing inside of the mare's hot, wet folds as her walls clenched tighter around him. "Aaahhh~"

The mare looked down at him and giggled. "That feels good, doesn't it?" It was Luna. She had been bouncing herself gently up and down on his member, tightening her inner walls around his erection each time she came up.

"Careful Sister, we don't want him to cum just yet." Another voice came from behind the two. "Besides there's still more I have to teach you about this." Celestia came into full view. She brushed some of her little sister's hair out of the way before kissing her affectionately. "Now as for you," She turned to Shining Armor who was in pure bliss and lowered her head to him.

Before he could protest to anything else Celestia had started licking and sucking on his horn. Against his will he could feel himself getting closer and closer to his release. "M-more... Aaahhhh..." He couldn't stop himself. He was woozy and confused, but at the same time he felt so good like it was a dream come true. As he was nearing his climax, Celestia had them stop, making him pout in reply.

Luna looked at her sister curiously as her horn started glowing. "Sister what is it?" Luna was baffled as she was pushed down so that she was pressed to his chest with his cock still buried deep inside her pussy. "Tia?!" She gasped as she felt something long, wet and cold rub against her other hole.

"Just relax Lulu." Celestia strapped on a replica of another stallion's cock to herself and started to rub against her sister's tight hole. After adding more lube she was able to slip it in and started rocking in unison with Shining. "See? Doesn't this feel good? Now do as I taught you."

It didn't take long for him to figure out what she meant as Luna leaned forward. He moaned out loudly as she copied Celestia in sucking on his horn. He began to thrust faster and harder. From Luna's tight marehood, to her hot mouth sucking him off and Celestia's strap on's balls slapping against his at the same time he couldn't take it. To make it worse Luna used her magic and started thrusting in her with a double dildo they had intended to use earlier.

Both sisters moaned in pleasure. Climaxing together and then helping him to receive the same release. They got off of him and cleaned him up. Celestia kept him steady as Luna put him in a sort of trance. They made sure to make him think it was all just a dream. If anypony else were to hear of it, they would be in trouble.

A thought passed through Luna's mind and she used her magic to make him open up to her. "Tell us. What is it that bothers you so?" She inquired, hoping that it was just stress and that their time together could happen again.

"I lost the love of my life." Shining started to open up and also wake up from his daze. Thoughts of Rarity started filling his mind again. He regretted 'dreaming' of such acts and with his Princesses none the less. His 'dream' was quickly turning into a nightmare that he wanted very badly to wake up from.

Celestia seeing his pain used her magic to bring the bottle over. She walked the three of them back up. Making sure the coast was clear, she then dipped the bottle into the fountain that had filled itself back up. "Shining Armor, drink this." She handed him the bottle and the pill from before.

He looked at it confused. "What is this?"

"It will make your pain go away. It will take away all thoughts of what ails you. But it will also cause you to forget about the time you had with her. The choice is yours to make." Celestia looked to her sister as she spread her wings. "Decide now while you have the chance."

Shining couldn't stand the thought of forgetting Rarity. However he also had to help guard them and couldn't do his best if he was distracted. He looked over at Luna who shape shifted into Rarity. "Rare! What are you doing here?"

Luna felt bad about what she was about to do, but knew it had to be done. She used her magic to trick him into thinking she was her. "What are you talking about? Leave me alone. Its over, I don't want to see you anymore." She felt awful, but if they were to keep him as their guard it had to be done.

That was it, he broke. Not thinking any further on the matter he took the pill and downed it along with every last drop of the water. Slowly he became drowsy which he found odd seeing how he was supposedly dreaming. As he slept for real all the moments he shared with the white mare, her feelings for him and his for her, all of them disappeared.

When he awoke again he was in his room. He looked around hazily. Everything seemed normal except for picture on his nightstand. He was sitting down with a white mare and they were smiling. Entranced he stared at her a while. "Who is she?" He mumbled to himself before accidentally bumping the picture into the trash as the alarm rang. "Oh no! I'm gonna be late! Their niece is here today!"
