The Secret of Shining Armor

Twilight Velvet was siting at a table inside her home eating her breakfast. She wore a white plain t-shirt and blue jeans as she was wondering what to do today. Her meal was just simple cereal with coffee to help wake her up during the very early morning hours. During this time she would see he husband, Night Light, across the table with their son, Shining Armor, right between them eating their breakfast as well.

This morning was different though, as evidence by the absence of both of her usually family members that ate with her for breakfast. Her Husband had an excuse to be absent form the table as he was in a different city for about a week for his work. Her Son on the other hand did not have an excuse though.

The older mare knew what her Son was doing the previous night as he was home doing 'homework' with his marefriend, Cadance. They would do this 'study session' almost once a month on a Saturday near the end of the month but she knew that those sessions were just a cover to say that they were having sex. Velvet knew everything that would happen in her home and even with all the precautions that the two young adults would do to prevent her and his father from knowing what they during, but Velvet knew what they were doing. She used that same excuse when she was dating Night Light when she was in high school.

Of course, the thing that was different today was that it was Monday and not Saturday when their session would end and Cadance left at night and not in the morning like she would usually do. Shining had to go to his Royal Guard training in about an hour and she had not seen him since last night when he lead his marefriend upstairs for their monthly time together in private.

'Maybe their session tonight was one of those nights that they experimented with certain toys that lead to an early end' The lone mare thought to herself as she was starting to finish up her coffee. She looked towards the stairs in some concern thinking about checking in on her Son but decided not to. 'I'm thinking too much about this aren't I. I know there is no need for concern as I know he will come down in about thirty minutes because I know he will never want to miss his Guard training.'

'Okay, enough is enough, I'm going up there,' Velvet thought to herself as she looked at the clock that was nearby the couch she was siting on. She decide that Shining may had been a bit too worn out to come out after his session last night but that thought went away when she notice that he was about three hours late for his training. She should have come upstairs when it was time for him to leave but she thought that maybe he was still worn out from the intense sexual experiments with new moves/playthings and did not want to disturb him.

The older unicorn mare walked up the stairs and went directly towards her Son's door. The door had nothing special on it besides his Cutie Mark on the door which was a blue shield with a pink starburst in the center and three small blue stars at the top of the shield.

"Shining? Is everything alright in there? You're very late for you Guard training dear," Twilight Velvet said out loud as she knocked on the door. She waited for a response but nothing came and decide to ask again. "Shining? I'm very worried about you right now? Please, can you open the door?"

A minute went by with still no response and decide that she needed to enter his room. "Alright, Shining, I'm coming in." Velvet stated as she went for the doorknob and slowly started to turn it.

Velvet expected that the door would be locked from last night but it was not. She figured that Cadance must have forgot to lock it when she left early last night. She open the door slowly and put her head in between the the crack of the door. "Shining, I hope nothing bad has ha-" she stopped suddenly as she was in shock at she discovered in the room.

The room was very basic with a desk to the side of the room and a bookcase next to it. A closest was across the desk which was open to show the various clothes that Shining would wear and the royal guard uniform that he would wear for trianing. A few posters were around the walls of the Royal Guard and a single poster of the Wonderbolts. Near the window, was the four poster queen sized bed with a small desk next to that had a small lamp that was illuminating the room. On the bed was what caused Velvet to stop suddenly and take in on what she was seeing.

With both of his hands and feet tied to each corner of the bed was the young stallion that she was looking for. His snow white coat was matted from his continued struggles of trying to break free. He had a horn ring that she knew would negated his magic and a blindfold that blocked his vision. A ball gag was place in his mouth with drool coming out from the side from how long it had been placed there. And what appeared to be something like headphones that were on his ears making him only hear the sound that was coming out from them and nothing else.

While that would have shocked Velvet, it really did not bother her as she knew about some of the toys that her Son and Cadance would use. She discovered toys like the ball gag when cleaning his room and she knew about the horn ring when he accidently went downstairs one time with it still on him. She was expecting to see Shining in a situation like this, it did happen to her when Night Light did something similar to her. The only difference was that she wanted to stay in that state for a few hours while Shining may have not wanted to be stuck like this.

What really shocked Velvet was what Shining Armor was wearing. At his feet, was high heel shoes and knee high pink socks. He wore bright pink panties which could barely contain his very hard and long cock and what looked like a dildo placed in his ass. He was also wearing a pink skirt with his tail coming out of the end, a pink bra that barely fit him and long fingerless pink gloves that went to his elbows. His royal blue mane with one stripe of teal and one stripe of a darker blue was put into a ponytail that was being held by a pink bow. She could also see that his nails were also painted with blue nail polish and could only speculate that his toenails were also covered in the same nail polish.

The door was fully opened now as she started to head towards the bed that her Son was tied down to. As she got closer, she could not believe what she discovered about Shining that he liked to dress up as a girl. Sure Velvet heard about stallions who would like to cross-dress as mares but she never expected her own Son to do stuff like this. She also guessed that Cadance knew about this little secret as well given the fact that she probably left him here like this when she left.

Velvet got to side of the bed and looked down at her Son with a look of bewilderment. "Hummmm!?" she heard her Son say something from his mouth which she guess was him asking who was there or asking if she was Cadance. Velvet slowly went for the blindfold and started to undo it. After it was untied, she lifted it off his head and discovered something else that was put on her Son. Light blue eye shadow was applied to his eyes to make him look more like a mare than ever before. And his bright blue eyes stared in shock and horror at who unblinded him.

"Mum?!" he said through his gag at the realization on who finally came to his aid after hours of torture tied to his bed. While he knew Cadance left to go grab something, he did not know that she left for a very long time for his Mother to eventually find him doing his monthly secret dress up sessions with his marefriend.

His Mother started to take off the headphones that were stuck on his ears for hours. Whatever was playing from the headphones was no longer playing as the batters for it died long ago. Right after the headphones was the ball gag which was easy to get rid of as she used to use similar types years ago. As soon as the gag was out of Shining's mouth, Velvet finally asked her Son what was on her mind when she saw him, "What in Celestia's name are you doing Shining Armor?!"

"Uh... Trying outfits for Cadance," Shining said with a sly smile.

Velvet put her hand on her face and let out a long sigh at his explanation. "I know that is bullshit Shining and I want the truth. NOW!"

Shining cowered at his Mother's yell. He knew his Mom would never yell unless she was extremely upset at something and the last time she yelled at someone was when she was denied access to visit Twilight at the Castle that one time. At least twenty guards were sent to the infamy for a month and before any more guards join them, she was stopped by Celestia when wondering what the racket was. After that incident, the Sparkle Family, especially Twilight Velvet, were allowed access to the Castle at all times.

"Well Mom, I will tell you everything if you can untie..." The tied-up unicorn started to say before he saw his Mother's stern face. Her face told him that she would not do anything until she discovered why her Son was tied-up and dressed up like a cheerleader for some sports team. "Okay Mom, I am dressed up like this because I like dressing up in girl clothes."

"What started out as curiosity about what is would be like to wear a skirt, lead to me wearing dresses and other such outfits like one-piece swimsuits or even a cheerleader's outfit which is what I'm wearing right now. Cadance discovered my liking of dressing up like this and started to help me discover what I like to wear. She provide all kinds of outfits that I would wear and we would even do some roleplay with the outfits once a month. I would dress up like a princess and Cadance would be my knight or we would both a wear a two-piece swimsuit and we would make out in the shower."

"Last night was the night were I would play a cheerleader and she would be my coach. I got dressed and we got way into more than usual and that was when I got tied down on my bed. She said that she was going to grab something in a different room but as you know Mom, she never came back," Shining stated as he let out a sigh at his explanation for the situation that he was in.

Velvet looked at her soon for a few seconds taking in everything that she saw and what Shining told her. She gave a sigh and looked at her Son with a soft smile. "I'm sorry for yelling at you but I was shocked that you would be into something like this. I know you would like to be release but I wanted an explanation about this before I let you go," She stated as she started to head towards the foot of the bed to untie his feet.

"Thanks Mom but uh... could you take out the huge dildo that is currently stuck in my ass because it's been stuck there for hours and it's starting to get uncomfortable," Shining said with a large blush to Velvet as she stopped what she was doing and looked towards his raging hard boner and dildo stuck in his ass that was being covered by the panties he was wearing.

She moved towards his crotch now instead of his tied feet and started to slowly take off the panties and notice how much bigger her Son's dick was compared to any stallion his age. His flat tip was spewing pre all over and it covered his dick and balls and made a large wet spot where the underwear was holding it in. His balls were massive, about the size of apples and they like they were holding a huge load of his sperm inside which has not be released for a long time. She stared at it in for awhile as she noticed that he probably did not cum for almost a couple of hours. She knew that what she was thinking would go against everything that she has grown up on but she knew that having this long of blue balls was very hurtful, especial for a young stallion his age.

She sighed and mumbled to herself, "I can't believe I'm about to do this," as she started to give light kisses to his dick. "Mom?! what are you doing?!" explained Shining when he felt his Mom start to give pleasure to his raging dick that was hard for hours. He then let out a loud moan soon after as his dick hasn't been touched for hours and was very sensitive.

Velvet gave a few more kisses before she started to give long slow licks while starting at her Son directly in the eyes. Shining looked down at his Mother and gave another moan as he realized how sexy his Mother looked when giving him a blowjob. He knew it was wrong to think about his Mother in such a way but even he knew how hot his Twilight Velvet was. Her perfect D-sized breast and heart shaped ass was nothing to complain about as even his best friends at school were jealous that his Mother had the body of a super model.

The crossdressing stallion let out another loud moan at the thought of seeing his Mother naked when giving him this blowjob and the intensity that his Mother was giving the blowjob. The slow methodic licks that would end at the tip of his dick was some of the best pleasure he has ever felt in his entire life.

Twilight Velvet on the other hand, was starting to get more into it as she went to the stage and placed her mouth over her Son's cock. The reaction was immediate as she felt a sudden increase in pre coming from the tip and with that increase, she started to slowly take more of her Son inside of her.

Velvet knew this was wrong but at the same time, she knew that if she left him like this for any longer, he could get some sort of health problem that might affect him for the rest of his life. The only thing that was keeping her going was thinking that this was Night Light's cock she was sucking instead of her Son's cock but she could only hold that illusion for so long.

She increased her speed and started to take more of his cock inside of her mouth before all of it disappeared behind her mouth. Deep-throating was one of her speciates that she developed when dating Night Light and she knew that this 'special talent' would always give out the biggest load of cum no matter what. She closed her eyes in concentration and continued for a good five minutes before she heard her Son yell, "I'm close Mom!"

The illusion that this cock was Night Light broke when she heard his words and before she could pull away, she heard "I'M CUMMING!"

Velvet felt a sudden large stream of cum start to come out and quickly stayed in place and swallowed as fast at it was coming out. She knew that any other sudden movement would make her choke as she started to taste the very familiar salty and tangy form of cum.

Shining came for almost a whole minute while his Mother stayed in place swallowing everything he had to offer. As the last spurt of cum ended, Shining let out a huge sigh of relief while his Mother swallowed the last drop. He looked directly into his Mother's eyes and gave a sheepish smile, "I'm sorry Mom, I just couldn't hold it in and I really needed to cum really badly and" but he was cut off when Velvet shushed him.

"It's ok my lovely little daughter," stated the grey unicorn mare as she licked her lips in satisfaction, "I think it's time that we head to the Main Course." Shining looked at his Mother in shock that his own Mom was willing to do it with him when he noticed strange little hearts inside of her eyes.

"Are you alright Mom?" asked a worried Shining Armor as his Mother started to undress in front of him. She took off her t-shirt and jeans which left her only in her black underwear. "Mom! Please you got to" said Shining before he felt something was thrown on his face that blinded him which was soft and wet. He soon realized that it was his Mom's Panties and he could not help himself but give a deep breath in through his nose and smelt how wonderful it was. It was the greatest smell that Shining Armor has ever smelt in his entire life and before he could think of anything else, he soon felt his Mother's arms on his chest.

"How's my little Cheerleader doing?" asked Velvet as she was starting to line herself up with her Son's still hard dick. "Well..?" she asked again as her dripping marehood was hovering over his dick.

"... I'm doing fine Mommy, your little cheerleader is ready for you," said Shining as he was starting to get into the roleplay that his Mother was making him do. He knew that he should stop her before she would impale herself on his dick but for some reason, he just could not bring himself to stop her and the heat of her pussy was making him want to have sex with his very sexy Mother.

"That's a good Girl," replied Velvet as she impaled herself onto Shining's dick in one fell swoop. They both moan at the pleasure that they immediately felt and stood still taking it all in. After a about a minute of staying still, Velvet slowly started to lift herself up from her 'Daughter' and right before his dick was completely out of her pussy, she went back all the way down.

Velvet was using Shining as support as she was moving rapidly on top of him and was moaning in pleasure at every bit of movement that she would make. Shining could not see anything thanks to the panties on his face but every time he would take a deep breath, he would get high on the intense smell that was coming from them which would cause him to moan in pleasure along with his Mother moving up and down on him.

They continued for what felt like forever for the pair as Velvet started to get more intense in her motions and Shining started to push upwards whenever his mother would move away from him. Their moans of pleasure was the only sound that they could hear that was until Velvet Yell, "I'M SO CLOSE!"

"ME TOO!" also yelled Shining.

And as soon as Velvet slammed herself onto his dick one last time, she finally came. Both moan in pleasure as they both came at the same time.

Velvet felt her 'daughter's' cum go deep inside of her as she rolled her eyes back at how intense it was. She never felt anything like this before and this was the most intense she ever felt when she came. Shining meanwhile was having the best orgasm in his entire life. Both could not take it much longer before they suddenly pasted out with Velvet landing onto of her Daughter in a loving embrace.

Five minutes later, Velvet slowly opened her eyes and then opened them wide as she got up and saw what she had done. She had no clue what had come over her but she had the sudden urge to have sex with her Son and call him his daughter. "Shining, Shining wake up please." she said in a worried tone.

She heard her Son give a moan and slowly shook his head to wake himself up and with the shaking, Velvet's panties were flung to somewhere in the room. "Mom?" he finally said "What happened?"

"Shining, please know that I don't know what came over me but please don't hate me for taking advantage of you." said Velvet with tears starting to form in her eyes.

"Mom, it's ok, I... I know that I should have protested more about you doing that to me but I also gave into the same lust that you were feeling" Shining said in a tone that was trying to comfort his Mother. Velvet gave a smile at his words as she started to untie her Son.

"So... what now Mom?" asked the now untied pony as he rotated his wrist to try and get rid of the numbness from being stuck in that position for hours.

"I don't know Shining, but I do know that I have to send a letter to your Instructor at the academy for why you did not come today." explained Velvet as she was picking up her underwear and clothes.

"What are you talking about Mom?" asked Shining as he started to undress from the rest of his attire. "It's Sunday today so I don't have training today."

"Shining, it is Monday and whoever told you that is a liar" explained Velvet as she started to put on her clothes. Shining started at his Mother as he realized who put them up to this. "So.. who told you the wrong date today Shining?"

"Cadance"

"That was so hot!" explained a naked pink Alicorn as she was just finished with her third orgasm. She looked at the crystal that was in front of her that recorded the whole scene that happened in her boyfriend's room.

She kept telling him that he should come out to his parents about his fetish for crossdressing but he would always respond with no and how he would be shammed by his Mother. Cadance decided that it was time for him to reveal his secret to his parents that she came up with the idea to tie him up in his room fully dressed in his favorite outfit on a day she knew that one of them would come to his room in concern for why he did not come out.

She told Shining that it was Saturday instead of Sunday so that his Mother could find him when he did not come down early for his guard training.

She never expected Twilight Velvet to start sucking off her own Son's dick a few minutes after her discovery but she knew that the older mare would only just suck his cock. The Alicorn decided to use her talents to 'influence' them to have sex with each other. While she just wanted to see them bang, she also kind of used it as a means to get back at Shining as she was also stuck in a similar situation by the same stallion. He had some sort of emergency at the academy that he forgot to untie Cadance when he left. She was tied up for hours until he came back and was thinking up a scheme to get back at him for the stunt he pulled on her after that day.

She gave a soft sigh of relief at how much everything worked out. "So... Is Shining going to start to be open with his crossdressing?" said the naked purple unicorn that sat right next to Cadance.

"I think so Twilight. I just can't wait for him to be everywhere in his cute dresses and then we can finally have that threesome that we always wanted to have with him."

"Yes, I can't wait to fuck the brains out of my Brother" explained an enthusiastic Twilight as she gave a kiss on the lips to the pink Alicorn, "I can't wait"

"Me neither Twilight."
