Spike awoke, feeling very well-rested. He’d spent pretty much the entire previous day just lazing on the bed with Rainbow Dash and eating snacks, as they had been told to take it easy for a few days. As he sprung to his legs, he felt his left foot sink into something soft and moist, and he looked down to see his foot sunken into a half-eaten slice of hay bacon pizza. He picked it up, brushed the lint off it and took a bite. It tasted rather dry, but it was better than nothing, and the thought of eating more potato chips almost made him ill.

Suddenly, a glance of something purple caught his attention at the edge of his vision. His heart leapt in his chest as he turned around to see Twilight sleeping peacefully at the edge of the bed. Rarely had he been so happy to see somepony. Forgetting about his hunger, he tossed the remainder of the pizza slice over his shoulders and made his way over to Twilight.

She was so cute and sexy where she lay sleeping peacefully that he just wanted to stroke her mane. He softly stroked her mane, savouring the feeling of her silky purple hair sliding between his claws. As he did so, she stirred and opened her eyes. Upon seeing Spike smiling down at her, she smiled back.

Without saying anything, Spike threw his arms around her neck and embraced her in a sloppy passionate kiss that lasted for a long time before they broke it off.

“Is that hay bacon pizza I taste?” wondered Twilight, raising an eyebrow at him.

“Yeah...” said Spike, blushing slightly and wishing he had a roll of breath mints handy.

“Got any left?” she asked, grinning sheepishly as her stomach rumbled loudly.

“Maybe... hang on a sec...” he said, walking over to the edge of the bed, reaching down over it and pulling out a cardboard pizza box from underneath it. Bingo! There were a few slices left.
Before he could grab one, Twilight had grasped one in her purple horn-light, levitated it over to her and started munching it down hungrily.

Rather than idly watching her eat, Spike picked up the slice he had discarded earlier, which had landed upside down on the pillow, leaving a moist triangular stain as he picked it back up, and resumed eating it. Dragons weren’t known for having weak stomachs, so he wasn’t really worried about the small amount of dust and pony hairs it had collected during its stay on the bed.

After they had finished off the remaining pizza slices, Twilight once again turned her attention to Spike.
“What have you been up to this week anyway?” she asked him, as her mind once again returned to the curious situation. “... and what happened to the wall?”
She glanced over to where there had once been a bookcase, but where there was now a large hole in the wall that had been inexpertly boarded up with what appeared to be pieces of the bookcase.

“Rainbow Dash crashed through the wall. As for what I’ve been up to... it’s kind of a long story. I’ll tell you later.” he explained.
“Your mane is a mess. Want me to brush it?” he suggested.

“Oh yes, please do.” she said, smiling sweetly at him.
“... and maybe you could start telling me about your week while you do?” she suggested.

Spike went over to Twilight’s dressing table and grabbed her brush from it, before returning to the bed. Twilight had laid down on her belly, making it easy for Spike to climb onto her back, from where he could easily reach her mane. Grabbing a lock of the purple hair in his left hand, he gently slid the brush through it with the other. He had to repeat the brushing a few times to get rid of all the tangles, and once it was straight, he moved on to a new part of her mane.

As he brushed her mane, he began to tell her about his experiences during the week. Of course, he left out a few details that he thought would be unethical to divulge on behalf of his friends - such as Fluttershy’s affair with Angel, Applejack and Big Macintosh’s barn adventures, and Rainbow Dash’s crush on Fluttershy. He could feel Twilight’s body quivering underneath him, as she occasionally giggled during the tale of his silly desperate hunt for someone to bang.

When her entire mane had been restored to its normal straight bookish-but-sexy style, Twilight prompted him to move on to her tail by flicking it playfully, brushing it softly against his back. He took the hint, and started brushing it it as he continued telling the riveting tale of his encounter with Rainbow Dash.

“Aerial intercourse?” Twilight interrupted, a mixture of worry and disbelief in her voice.
“What were you thinking?”

He shrugged. “I dunno. I was really bored. It seemed like a good idea at the time.” he said, continuing to brush her tail.

“Well, at least you weren’t seriously hurt.” she said, a tone of relief in her voice.

By the time he had finished telling her about his brief but steamy stay in the hospital, and how he and Rainbow Dash had spent most of the previous day relaxing in bed, eating snacks, Twilight’s tail was once again perfectly smooth.

Twilight turned her head around to face him.
“Would you mind brushing my coat as well?” she asked, smiling at him.

“Sure.” he replied, returning her smile. Hopping off her back and onto the sheets, he placed the brush against her side and began to brush her softly.

Twilight closed her eyes, letting out a sigh of satisfaction as the rough bristles of the brush slid through her smooth fur, pleasantly scratching her skin below, and taking with it any unwanted particles that had gotten stuck on her. She normally brushed herself using her horn, and was surprised at how good it felt to be brushed by somepony - or in this case, dragon - else.

As she lay there, enjoying the pleasant feeling of the brush against her flank, another feeling began to creep over her - one she hadn’t previously associated with being brushed. She felt heat spreading through her body, her breath getting heavier, and a tingling sensation in her loins. She could feel moisture beginning to form between her haunches. She was extremely aroused.

A soft gasp escaped her as the brush slid against her cutie-mark.
The brushing stopped.

“Hey, Twi... You alright?” Spike asked, snapping her out of her thoughts.

“What?” Twilight burst out, opening her eyes again. “Oh, yeah. I’m fine.” she said.
“More than fine, in fact. That felt... very good...” she said, giving Spike a sexy look.

She rolled over on her back, producing a crunching noise as her purple body landed on a few unfortunate potato crisps, crushing them under its weight. On the other side of the bed, Rainbow Dash shifted in her sleep, apparently stimulated by the sudden noise. Twilight giggled, unable to suppress her amusement at the ridiculousness of the situation. She stretched her hooves outward to give Spike full access to her belly.
“Please continue...” she begged, in such a sweet and seductive voice that it almost made Spike jizz his scales.

“Whoa, you sure have been enjoying this, haven’t you...” said Spike slyly, immediately spotting the dampness between her haunches. Twilight merely grinned back at him, blushing slightly.

Without hesitation, Spike went back to work with the brush, starting with her chest. He could feel her soft belly rising and sinking with her breath, as he steadily worked his way down towards her hind legs. Twilight let out a moan of pleasure as the brush grazed her teats, sliding in between her haunches and caressing her thighs, making her hind legs twitch slightly as the bristles tickled her sensitive places.

A gasp escaped her, as she felt a tiny claw sliding playfully through her slit, and she opened her eyes to see Spike licking his finger.

“You really want it, don’t you?” he said teasingly. “It’s overflowing down here.”

Twilight couldn’t deny this. She wanted him to fuck her. Badly. But there was one thing that was bothering her.

“I do... but what if she wakes up?”
Her eyes turned to Rainbow Dash, as she turned, mumbling in her sleep.

“Don’t worry about her. She already knows about us. She won’t tell anyone.” Spike reassured her.

Twilight smiled, relieved at this news.

“Is your body ready, master?” Spike said teasingly, a wide grin on his face.
He’d been looking forward to this moment all week.

“For you? Always! You are, after all my number one assistant.” Twilight replied, smiling back at him.

Twilight felt all giddy, her entire body tingling as she fixed her gaze on Spike who was now standing in front of her with a grin on his face. Even though they hadn’t been together all that long, she could hardly remember the last time she had been this horny. She stretched her hooves outward, parting her hind legs, fully exposing her moist nethers to her number one assistant.

Unable to restrain himself from his lust any longer, Spike dove in between her haunches, parting her mound with his snout, and plunging his forked tongue into her moist marely cavern. Her body gave a twitch of excitement, as he began to probe her interior, tickling her slick sensitive walls as his tongue darted around inside her love tunnel, pleasuring her to the best of his ability. Soft gasps escaped her muzzle as he continued his oral ravaging of her marehood, nibbling teasingly at her clit while his tongue worked her insides.

Spike could feel her breath quickening rapidly, and her body quiver underneath him as he worked her, and knew that she was nearing an orgasm. As he concentrated all his attention on her love button, it didn’t take long before she came hard, her entire body shaking with pleasure, her inner walls clenching down on Spike’s tongue. A loud moan escaped her as she started gushing out her juices, drenching both his face and the sheets below in marecum, prompting Rainbow Dash to stir once more, moaning softly in her sleep as she apparently entered a wet dream.

He continued working his tongue inside Twilight’s convulsing hole and playing with her clit until her climax subsided, and her body stopped twitching. She lay still on the bed, her face flushed and her eyes closed, heaving for breath.

Having regained her breath somewhat, Twilight opened her eyes looking up at Spike. An idea suddenly struck her, as she realized she hadn’t yet had her morning pee. Placing front hooves at her opening and parting her lips, she relaxed her bladder, releasing a thin stream of piss onto the dragon, aiming it directly at his balls.

As the hot yellow stream hit Spike’s sensitive crotch, a wave of pleasure shot through his body, and he instantly felt his member growing even harder. Wild with lust, as her warm urine splashing against the underside of his shaft and balls, running down his legs and forming a dark yellow pool around his feet, he grabbed his rock-hard cock and shoved it hard into her still-pissing cunt, blocking the flow as he began to pump into her, making wet squishy noises and causing her to gasp loudly.

Rainbow Dash began to twitch in her sleep, and was abruptly awakened by an involuntary moan coming out of her own muzzle, and the feeling of wetness forming between her hind legs as she rode out the remainder of a dream-induced orgasm, her eyes clenched tightly shut.

She was feeling rather embarrassed at herself, when another loud moan from Twilight snapped her out of it and drew her attention to the action taking place on the other side of the bed. Quickly pushing opening her eyes and pushing herself into a sitting position, she looked over to see Twilight lying on her back, moaning and gasping, kicking her hind legs involuntarily in the air as Spike drove his scaly glistening stake into her nethers over and over again. With each of Spike’s thrusts into his purple marefriend, faint crunching sounds erupted from underneath Twilight’s body, as the remaining artifacts of last night’s snacking were ground to dust under her weight.

Almost the entire length of the bed’s sheets were damp, and a few soggy potato crisps were in the process of dissolving on top of the damp spots. Rainbow Dash picked one up and ate it. Mmm. Extra salty!

Watching her two friends going at it, apparently oblivious to her presence, was making her horny again, sending her loins into overdrive. She looked down between her hind legs, and stuck one of her front hooves down there to feel the moisture. Fuck, I’m horny... she thought. Then, as she looked up again, her eyes fell on Spike’s pointy ribbed tail, bouncing up and down as he fucked Twilight, and a smile spread across her face as an idea struck her.

* POMF *

Spike was lost in pleasure as he slammed his cock repeatedly into Twilight’s wet cunt, his balls slapping wetly against her furry crotch, when suddenly he felt something brushing against his tail.

“So, you guys think you can have all the fun without me, huh?” said Rainbow Dash behind him, a tone of faux disappointment in her voice.

Spike felt his tail being grabbed by hooves and tilted upwards, shortly followed by something wet and fuzzy brushing against it. If his cock wasn’t already about as hard as it could possibly get, it probably would have gotten even harder. He heard a sigh of pleasure from behind him, as something warm and slippery began to envelope his tail, slowly lowering itself onto him until he could feel moist fur pressing against the base of his tail, dribbling liquid down to his butthole.

Having taken Spike’s entire tail inside her, Rainbow Dash began to ride it, slowly at first, getting used to the sensation of his hard scales massaging her insides, and gradually increasing her speed as her arousal increased. She was surprised to find that the sight of Twilight’s flushed face, dripping with sweat as her assistant fucked her, was an extreme turn-on to her. For a moment, she wished she could bend over Spike’s shoulders and kiss the sexy purple mare. Aroused even more by these dirty thoughts, she began to fuck Spike’s tail even harder, grinding her chest against his spiny back.

Spike was almost breathless, partially because of pleasure, and partially because he was now being pressed down into Twilight’s chest by Rainbow Dash grinding her body against him. At this point he could barely move anymore, but it didn’t even seem to matter anymore, as Rainbow Dash’s lustful humping against his back was slamming him into Twilight even harder than before. He could feel her warm chest fuzz brushing against his back as she rode his tail, moaning loudly, her eyes rolled back, and her tongue lolling out of her mouth, dripping sticky warm saliva onto him.

Rainbow Dash was almost in heaven, grinding her clitoris roughly against Spike’s scaly tail, and enjoying the sight of Twilight’s body squirming with pleasure in front of her. No longer able to restrain herself, she bent over Spike, grabbing Twilight’s neck and locking her muzzle onto Twilight’s in a wet sloppy kiss. Twilight opened her eyes, clearly surprised at this forward act, but didn’t resist - on the contrary, Rainbow Dash thought she looked happy. Twilight returned the kiss, wrapping her hooves around the blue mare’s neck and pulling her even closer, pushing her wet tongue into her mouth. Rainbow Dash could taste the remnants of yesterday’s hay bacon pizza in Twilight’s mouth, as they began to make out sloppily.

Spike was both surprised and aroused by the action taking place around him, and combined with the sensation of the two mares’ bodies squeezing him between them like the hay in a hay sandwich, this new flood of arousal caused him to erupt into an explosive orgasm. With a loud grunt of pleasure, he began to blow his load inside Twilight’s hot wet pony pussy, filling her up with his hot magical dragon cum. The feeling of his warm juices flowing inside her was too much for Twilight, and she almost instantly came as well, drenching both Spike and Rainbow Dash’s hooves in marecum, while simultaneously releasing her bladder, squirting out a hot yellow stream of piss around Spike’s cock.

The feeling of Twilight’s warm urine and marecum splashing against her legs and pooling up around her hooves, quickly brought Rainbow Dash into orgasm as well, and after firing her first few gushes of cum, she too let go, squirting her hot amber morning piss down Spike’s tail and butt, and onto the sheets below where it mixed with Twilight’s. Her muzzle locked with Twilight’s, she continued their exhilarated makeout session, her outstretched wings twitching and flapping erratically in correspondence with the orgasmic pleasure rocking her body, while letting their pee and marejuices flow around the dragon writhing and spasming between them as he shot his loads in Twilight’s pissing cunt.

Spike had never experienced anything quite so intense before. A pungent smell of urine, cum and wet pony fur wafted up around him as the two mares bumped him between them as though he was a double-sided dildo. The feeling of Twilight’s warm piss caressing his balls while Rainbow Dash’s piss simultaneously flowed down his tail over his butthole sent him into another explosive orgasm before the last one had even ended.

For what seemed like several minutes, they lay in a steaming heap on the urine-soaked bed grinding their bodies together, and grunting and moaning as they repeatedly set each other off in a seemingly neverending chain of orgasms.

When they finally came down from their orgasms, Spike crawled out from between the two sweat and piss-drenched mares to catch his breath. Rainbow Dash broke off her make-out session with Twilight, and rolled off her. For at least several minutes, they just lay still on the bed, heaving and panting, staring into the ceiling.

“Wow. That was intense.” said Twilight, breaking the silence.
“Where did you learn to kiss like that, Rainbow Dash?” she asked.

Rainbow Dash chuckled beside her. “A certain pink party pony taught me.” she said, and then added, grinning and winking at Twilight “... and you sure seemed to enjoy it!”.

“Yeah... I did enjoy it.” said Twilight thoughtfully, staring into the ceiling. I never thought I’d do anything like that with another mare. Much less like it. she thought.
She’d read something about this in a book. Bisexuality... that’s what it was called, if her memory served her right.
Was that what it was?

“So... you and Pinkie are together?” she asked, turning to Rainbow Dash again.

“Nah. We’re just friends.” Rainbow replied. “She’s fun to be around and all, but I don’t really feel that way about her.”
“She sure does know how to have a good time though.” she added, grinning.

“But you... you know... like mares?” Twilight asked.

“Not exclusively. But yeah, I generally prefer mares.” Rainbow replied.
“Your little assistant here,” she indicated Spike with her hoof “really knows how to please a mare.” she complimented, prompting a satisfied smile from the sticky worn-out dragon.

“He certainly does.” Twilight giggled. “Thanks to a certain pink party pony.”

As Twilight finally mustered the strength to push herself into a sitting position, and allowing her a glimpse of the mess they had made on the bed, a single popcorn floated silently across the puddle on the sheets. Unable to contain herself, she broke into uncontrollable laughter, hammering her hooves into the pillow. Spike and Rainbow Dash weren’t sure what she was laughing about, but pretty soon they too broke into laughter too, and then they all laughed, pounding the bed with their hooves and claws, until their chests hurt and they could laugh no more. Completely exhausted, they soon drifted off to sleep.
