Chapter 3 - An Awkward Evening at Home

Twilight Velvet almost skipped over to her dining room table, carrying a plate of thick veggie sausages in her magical field. "Let me just say again what a wonderful surprise this is! I hardly see my kids once a year, then all of a sudden everyone is in Canterlot in the same week! Why, this my be the first family dinner we've had in years!" She set the plate down on the dining room table, slapping away Night Light's hoof with practiced ease as he reached to snag a sausage early. "And with Cadence here... it's just like old times!"

"Thank you for inviting me in to your lovely home as well, Mrs. Light." Starlight Glimmer smiled, as Twilight Velvet took her seat at the table.

"Of course, Starlight! It's so good to see my little Twilight making friends! She's gotten so much better at it over the last few years... now if only she could become as good at finding a solid coltfriend..."

"M-mom!" Twilight Sparkle moaned, her face a tomato red (though she had been in a constant state of blushing since learning her brother was also home).

"What? Can you blame a mare for wanting more grandfoals?" Twilight Velvet smirked, patting her daughter's hoof. "Speaking of which, how is that little angel, Flurry Heart, doing?"

Cadance smiled and responded, "Wonderfully! I just got a letter from the royal daycare and she's getting along great with the other foals on their weekend mini-camp... I know it's good for foals her age to get a little time away from their parents so they don't get too attached, but I have to admit... it's really hard on me to not worry about her every two minutes!" She let out an exasperated sigh.

"Well its the stallion's job to make sure his mare is distracted when the foals aren't around." Velvet slyly stated, waggling her eyebrows. As she did this, she used her magic to place a sausage in Night Light's plate... waggling it and jokingly stroking the length of the sausage with her magic before placing it down.

Now both Shining Armor and Twilight Sparkle shouted with the same breath: "M-MOM!" as Cadance, Starlight and Night Light chuckled behind their hooves.

"You two have always been too easy to tease." Night Light laughed, "Still, she isn't wrong son... make sure you take care of your beautiful wife."

"D-dad! You too?" Shining groaned.

"Don't worry Night Light, I can guarantee you your son has no problem in that department..." Cadance laughed while adopting bedroom eyes, floating the longest sausage with her magic from the serving tray to Shining's plate, drawing the magic field sensually up the length before flicking the tip and placing it in front of her husband who chuckled nervously with a gulp.

Twilight slapped a hoof to her face and looked at Starlight apologetically. "I am so sorry about my family, Starlight Glimmer... they weren't always this embarrassing..." Her discomfort caused everyone else around the table to laugh.

Dinner went along with less lewd jocularity, the conversation turning to life in Ponyville, the Crystal Empire, and Canterlot. Twilight found herself having a tough time eating her sausage, unable to separate the meaty cylinder in front of her with thoughts of the meaty cylinders under the table.

Unbeknownst to Twilight, when Cadance had done her little show with the sausage, she'd displayed her magical talents to her husband, mirroring the magic she'd been using on the sausage simultaneously with a magical field on her husband's shaft. She'd drawn the field up his sheath, finishing with a little flick to his flaccid head which caused him to gulp nervously.

Since Cadance had been playing non-stop magical 'footsies' with Shining. She was good at concealing her activity, hiding her stroking and grasping of Shining's cock by making sure she was manipulating something on the table at the same time. Shining did his best not to react - Cadance always tended to be a little kinky about anything sexual, and he knew from embarrassing experience that she would only take things to further extremes if he started to protest or try to shut her down.

Shining had no choice but to try to endure her deft magical touch, as she traced the contours of his veiny cock, her magical aura alternatively grasping and tickling his medial ring... dancing along the ridge of his cockhead, and lightly massaging his balls. Shining had quickly extended to a full, throbbing erection. He knew he was a very well-endowed stallion but this was a situation in which that was not to his advantage, as his penis quickly hit the underside of the table, and lengthened further - the top of half of his shaft was pressing against the cold wood. He half-suspected that if the table wasn't laden with plates and food right now, he might be able to lift its weight with the force of his erection.

Suddenly, Twilight Sparkle dropped her fork under the table. Shining froze, mortified as he wondered if his little sister would reach under the table with her magic or duck under personally to pick up the utensil. Seeing her start to duck under the table, he panicked... with his entire force of will he tried to force his stallionhood to deflate before she could go under and see him in his full glory. He was almost successful too, until Cadence realized what was going on and, with an impish smile, clasped her magic around the base of his shaft, locking the blood in his penis and preventing him from shrinking... if anything her pumping grip caused him to engorge to an even veinier fullness. He tried to squeak out a protest, but was cut-off prematurely as one of Cadence's magical tendrils slipped up his rosebud, tickling his prostrate from inside. At this point, Shining could only swallow with nervous fear as he watch his little sister duck her head under the tablecloth in search of her fork...

Twilight was chuckling absent-mindedly at one of her father's dry, terse jokes as she ducked under the table cloth so she could see where her fork had fallen and snatch it in her magical glow. As her eyes gained focus in the low lighting under the cloth, she noticed a strange faint glow coming from her left. Looking over in that direction, she immediately noticed the pink colored field of Cadence's magic stroking what looked like some kind of horrific growth coming out of her brother.

'No... wait', Twilight thought, blinking to focus her eyes, 'was that one of his legs? No it couldn't be, its ebony black and throbbing and... eep!'

Finally, it clicked in Twilight's head that the massive, veiny appendage was her brother's penis. Her eyes traced up the powerful and thick tube of flesh, following along as Cadance's magic slowly stroked from the wide base of his organ, up and over the terrifyingly prominent medial ridge, and finally tracing up to the fattening flare, which was weeping a thick liquid that invaded Twilight's nostrils with a sickly sweet musk that made Twilight... uncomfortable.

With a breathless gasp, Twilight shot back up in her seat, her wayward fork long forgotten. She did everything she could to avoid making eye contact with either Cadence or her brother... and from what she could see out of her peripheral vision, they were doing the same. Red faced Twilight did everything she could to focus on her food, trying desparately (and failing miserably) to avoid thinking about what was taking place under the table mere inches from her.

Shining Armor was fit to explode in more ways than one. His adventurous wife was taking things way too far yet again. He knew she was bold and initiated most of their sexcapades, but this was over the line. His little sister had surely just seen what she was up to under the table. No amount of coughing, subtle elbows, or hasty glares seemed to be communicating the message to the pink alicorn princess of love, however... she continued to chat obliviously with Twilight Velvet as if nothing was happening even as her magic slid under his egg-smooth testicles to knead his taint. OK, that was far enough. Deciding that he could only salvage the most awkward ending to a family dinner by taking command of the situation, Shining picked up his wine glass, his horn shimmering with blue magic as he levitated the glass haphazardly. 'Perfect' he thought, 'now that I've got the cover for why my horn is glowing...' he bit his lip in focus as he directed a magical energy field under the table, tracing along his wife's left hoof, up her leg and into her nether region.

Immediately, he could feel the moist heat through his magical sensory field. She was really worked up! Shining traced around the outside of the puffy, swollen pubic mound, squeezing and teasing with a warm massage that assaulted from all angles at once. It was only a few moments of this treatment before he felt her clitoris slide out of its hiding spot, pushing open the folds of her labia with an small squelch.

"So how are you finding the teething process to be going, Cadence?" Twilight Velvet asked as she rose from the table, beginning to clear some of the assorted plates.

Shining knew that he should stop immediately lest Cadence's response give away the game with a moan or throaty groan to his mother... and Cadence had stopped stroking his shaft - a sure sign of a deescalation in their sexual scuffle - but he was feeling vengeful. On the next throbbing wink, he slipped his magic field into the first half-inch of the soaked pussy, delicately stroking the clitoral bulb from inside its moist cavity.

"Oh, not so bad! At first my teats felt like chewed hay, but she quickly learned not to nip!" Cadence chuckled, her voice completely devoid of any reaction or indication that Shining's ministrations were having any effect on her.

'What?' Shining wondered, somewhat annoyed. Usually Cadence ran pretty hot: she would not hesitate to wake the dead with her vocal screams of pleasure. He didn't think she had it in her to maintain such composure and, being the macho stallion he was, this was taken as a challenge to his masculinity.

Renewing his efforts, Shining slipped the magical field deep into the wet vagina it was playing with, forcing apart tight fleshy petals that churned and gripped at his field. 'Damn,' Shining grimaced while focusing, 'Cadence is tight today, she's been doing those exercises again!' his thoughts served to arouse him further as he imagined his wife clenching and unclenching her marehood to strengthen her pelvic floor muscles for him. 'Still,' Shining nearly grunted aloud as he mused, 'this is a bit ridiculous! I can barely squeeze deeper then a few inches deep!' he struggled to explore deeper into the hot, twisting cavern. The throbbing clitoris had a mind of its own, now. It fired off in random but continuous struggles, clearly orgasming from his attention as his magical field sensed the slight splashing of fluids seeping from the parted, sticky lips.

"I do have to say Velvet, this dinner was absolutely delicious! Did you really cook it on such short notice?" Cadence chuckled as she stood to walk to the kitchen, having stacked some of the plates in her own magical field. Shining was aghast as he watched his wife walking to the kitchen without a care in the world, totally nonplussed by his hard work! Frustrated, he used his field to grip the clitoris and vibrate it furiously, triggering a clenching, squirting orgasm that splattered outwards... it was finally at that exact moment that he realised. His wife was walking away... there was none of his field around her... then where?

He froze.

He felt his stomach plummet through the floor. No, through the crust of Equestria, and deep into it's molten core.

He ever so slowly turned his head, toward his right. Scanning across the table to where Starlight Glimmer was sitting. Maybe he'd gotten her by accident? It would be bad, yes... but still better than the alternative.

But no, Starlight Glimmer merely looked back at him with an arched eyebrow, as if to say 'What the heck are you staring at?' Then her face suddenly changed to one of concern as she looked to Shining's right and asked aloud, "Twilight!? What's wrong?"

'Oh Celestia, please no!' Thought Shining as he looked to his right.

"Honey? Are you OK?" Shining barely registered his father's worried tone as he looked at his little sister, two places down from him, her head slumped on the table, sweating profusely, her tongue hanging partly out of her mouth with bits of drool coating the underside of her muzzle, her eyes shut tightly as she let out a soft, pained moan. Her hooves were beneath the table, obviously down in her stomach area.

"Do you have a stomache-ache sweetie? Was the food not to your liking?" Twilight Velvet asked from the kitchen with concern.

"Unnnngggghhhh... n-no," Twilight groaned out as she lifted her head lazily from the table.

Shining was doing his best impression of Discord, pre-escape from the statue garden. His natural defense mechanism had kicked in. Perhaps, if he didn't move, he would eventually just die in this exact spot, resolving all of his problems.

"I-I need to g-get some rest." Twilight shivered as she regained control of her muscles, shakily stepping off the dinner chair and walking toward the stairs. She had to use some magic to hold her tail down as it involuntarily tried to flag up in the air to reveal her arousal. Shining's last hope, that he had perhaps been rubbing one out on a mare somewhere else in Canterlot, or that his magic field was feeding him entirely false signals was crushed as he noticed the silvery strand of marejuice trailing from under Twilight's tail to her chair. Looking down slowly, he saw the puddle of marecum where Twilight's butt had just been, confirming his worst horror.

He had just fingered his little sister to orgasm.
