The next weekend

Twilight sighed contently as she basked in the moonlight glow in her study, a book on the desk before her and a glass of water by her side. She was wearing a blue skirt and a button-up shirt, as well as a pair of glasses one would easily associate with a nerdy librarian.

Twilight took a sip of her water and turned the page of the book she was reading, the pages cast in a dull glow from the few candles she had spread nearby. Tonight she was feeling really good, and would probably sleep very good too.

A light knock came to the door of her study and she called out “come in” and the door slowly creaked open, her assistant and pseudo-son Spike stepping in; he had his hands clasped behind his back and was staring at the floor.

He made it a few steps past the door and stopped.

“Spike? What is it dear?” Twilight said, closing the book and leaning back.

“Mommy...I did something really bad...” Spike whimpered in his sweet little voice, his eyes never leaving the floor.

“Oh? Why don’t you come over here and we’ll talk about it. It’s OK” Twilight said soothingly, offering her lap up.

Spike slowly came over and sat in her lap, making sure to keep his eyes from Twilight’s, who was trying to do the opposite.

“Tell me what happened, sweetie.”

Spike sniffled and wiped his eyes before beginning. “Ah- ah was just downstairs in the foyer, readin’ one of your books, an’ I sneezed an accidentally set it on fire I'M SO SORRY I didn’t mean to it was just an accident!” he cried, looking really guilty.

“Oh that’s OK, Spike, I’ll just get a new copy” Twilight smiled, comforting her sweet little son.

“Y-you’re not mad?” Spike asked.

“Of course not. What book was it?” the Unicorn inquired; she was a little upset but it wouldn’t do any good to let Spike know that.

Spike sniffled and said “i-it was that really special one that Princess Cels-Celestia got you for your birthday.” He stumbled over the Princess’s name like he always did.

Twilight blinked a few times and said “you mean...that book?!”

“Y-yes.”

Twilight was floored; that book was very special to her, it was the best book she had ever gotten. Full of amazing details on astronomy and the universe that had been created for them by the Princess. And Spike incinerated it.

Twilight sighed in disappointment. “Spike...please get up and bend over my lap” the Unicorn gently ordered.

“No! Please, mommy! I didn’t mean to do it! Please, don’t!” Spike yelled, upset.

“Now, Spike” Twilight commanded.

Spike wiped his eyes and slowly got off Twilight’s lap, turning and beginning to bend over her knee; he was shaking as he did so. When he was in place over the Unicorn’s lap he lifted his tail to allow unobstructed view of his naked butt.

Twilight’s horn took on its purple aura as she opened a box under her desk and retrieved a wood paddle, one that had holes strategically drilled in it to move through the air faster. Spike took one look at it and began to cry, though he stifled his sobs so they wouldn’t be too loud.

“This will be good for you” Twilight told him, gripping the paddle tightly with her magic and swinging it through the air, smacking the item against Spike’s backside, a strike that made him yelp out.

Again and again and again Twilight spanked Spike, bringing the paddle against his butt close to twenty times and not showing any sign of slowing down. By now Spike had calmed down and was silently taking the paddles, though the tears were still coming out of his eyes.

Twilight cocked the paddle back far above her head and swung it, the device soaring through the air straight and true and slamming extra hard against Spike’s butt.

“Ah, pineapple!” Spike screamed, and Twilight immediately stopped.

“Are you OK?!” the Unicorn asked, lowering the paddle and looking down at her drake.

“Y-yeah, just that one hit really hard. It’s like you were actually spanking me for burning one of your books!” the dragon explained.

“Want me to ease up?”

“Yes, please.”

“OK... Now, where were we? Ah yes” Twilight said, bringing the paddle back up as the two of them got into character once again. Twilight spanked Spike for another twenty times before dumping the paddle to the side. She kept a hoof on his back to keep him in place.

“There. Did you learn your lesson?” Twilight sternly stated, looking down at Spike who still had tears coming out of his eyes.

“Y-yes, mommy” the dragon answered with a sniffle, nodding as well.

“Good. Now get up and go to your room” the Unicorn ordered, about to release her hold on Spike when she looked back at his rear end; his penis was out and fully erect, and even quivering a little as the head brushed against her leg.

Twilight smiled and knew that Spike knew she was looking back there, but kept in character when she spoke again. “Actually, stay here and bend over the desk. Don’t move” Twilight said, letting Spike get up and do as told as she reached into the box under her desk once again, pulling out the strap-on dildo and lubricant Rarity had provided her.

She applied the lube to the strap-on and put it on, applying a little to her hoof and rubbing over the entrance to Spike’s butt which made him perk up and look over his shoulder at her.

“W-what are you doing, mommy?” the dragon inquired, forced to look ahead when Twilight climbed over on top of him, something cold and wet pressing against his little butt hole.

“Shh, I’m not mommy anymore, I’m Mistress” Twilight said, forcing a ball-gag into Spike’s mouth and securing it in place as she prodded the head of the dildo against Spike’s anus.

With a little gentle prodding and some force, Twilight finally entered Spike’s butt with a light pop, slowly pushing the dildo into his butt and loosening it up. Spike whimpered but looked alright.

Twilight bottomed out against Spike’s rump and began to pull back, the lube greasing up his little hole well enough for her to easily retreat. After a couple more slow thrusts Spike’s anus loosened and greased up enough for the Unicorn to increase speed, steadily thrusting the dildo in and out of Spike’s butt.

“Do you like that, you little slut?” Twilight whispered into Spike’s ear, earning a muffled moan in response. She licked his little ear barb and continued pumping into his ass, which was now greased up enough for her to start pumping rhythmically at a decent pace.

Spike’s moans and whimpers were muffled by the ballgag, but Twilight could tell his naughty little ass was enjoying it. Twilight stole a glance around his body and saw his cock fully erect and throbbing with blood, the slender and long appendage quivering and leaking pre-cum on the mare’s desk.

Twilight smacked the drake’s tender rump with a hoof and he winced and whimpered, looking back in confusion as Twilight pressed her face against his cheek. “Your little cock is dribbling cum all over my desk, you naughty little boy. Do I have to punish you more?” Twilight said, pulling the ball part of the gag out of Spike’s mouth and letting him speak.

“No, Mistress. I’m sorry but I can’t help it” the dragon whispered pathetically, earning another smack on his ass from the Unicorn.

“No excuses, mister” Twilight replied, shoving the ballgag back into his mouth and resuming her thrusting, pumping in deep enough for the head of the dildo to brush against his prostate, making him whimper and moan more and assuredly making his cock dribble more pre-cum out onto the desk.

A quick check confirmed this.

Twilight smiled as she looked over at Spike’s face, his eyes were closed and the ballgag was quickly becoming coated in saliva leaking out from his lips. Each thrust into his butt ended in the head of the dildo rubbing against his prostate and a moan from the drake.

Twilight undid the ballgag completely and let it fall to the desk, pressing her face once again to Spike’s cheek and whispering into his ear. “You want me to stroke your cock, don’t you? I bet you’re so desperately pining for attention down there from all the stimulation you’ve been receiving in your tight little ass. Say it. Tell me you want your little cock stroked” Twilight demanded.

Spike was silent for a few moments as he resisted, but finally caved in and yelled “oh yes! Yes, please! Please Mistress, stroke my little cock! Ooooohh it aches so bad! Please stroke it!”

“Beg for it!”

“Pleaaaasee, Mistress! Pleaaase stroke my little dick! I need it, please! Oh sweet Celestia plea-OOHH!” Spike yelled and nearly collapsed as Twilight began magically stroking along his shaft, the aural field taking the shape of a ring and lightly rubbing back and forth down it. Spike practically screamed to the high heavens in pleasure as Twilight worked her literal magic.

“Oohh yes, thank you!”

Twilight continued to pump away into Spike’s little ass while jerking him with her magic, the internal and external stimulation quickly rose up to too much for Spike to bear and he came. Hard. His semen shot out across the desk and even a little onto the floor beyond it. Spike squeezed his eyes shut and opened his mouth to yell but couldn't make a sound except for an odd stutter at the end. The dragon’s orgasm lasted for close to 40 seconds before finally subsiding; Twilight pulled out of him and he collapsed into the chair, his head against the desk and his chest heaving.

Twilight lowered her head and licked up all of his cum off the table and the excess off his cock, making him buck a little. She made sure to get all of it that she could find before grabbing Spike’s jaw with her hoof and slipping her tongue into his mouth, snowballing most of his own cum into it before she pulled back. A few strands of semen/saliva mix connected them before being broken, and both of them swallowed the semen in their mouths. Twilight smiled at Spike’s glossy eyes and his content face.

“Thank you, mistress” the drake breathed, still breathing heavy.

“Just Twilight now, thank you” the Unicorn replied, taking the strap-on off and putting it back in the box, along with the lube and paddle.

“So, how was it?” Twilight asked, sitting down in Spike’s lap.

“...Can I be on bottom permanently, now?” the dragon said, earning a little giggle from Twilight.

“That wouldn’t be fair to me, then!” the mare joked.

“Yeah, I guess so. Anyway, let’s say we go to bed, yeah?”

“Sure.”

The two wobbly got to their hooves and feet and went upstairs to the bed, where they climbed in and snuggled together, exchanging a kiss.

“I love you, Spike.”

“I love you too, Twilight.”

-=-=-=-

....

“Drinking my own cum doesn’t make me gay, right?”

“Go to sleep, Spike!

Author's Note

I was shaking while writing the opening scene with Baby Spike and Momma Sparkle spanking him; that kind of scenario is a big fetish/fantasy of mine. When/if I ever get a lover into that kind of stuff we'll even use the same script.
