Barb grabbed a carrot and, with one of her claws, peeled it expertly.

"Study time, come on grab your friends,"

She grabbed a knife off the rack and deftly cut the vegetable.

"We'll research very... distant lands."

Using the knife, she pushed the cut carrot into the pot and started stirring.

"With Barb the Drake and Dusk the Pony,"

She opened a can of tinned vegetables and tipped the contents into the pot.

"The fun will never end, it's-"

"Barb!" A stallion's voice called out. "Is dinner ready yet?"

"A few more minutes, Dusk!"

Dusk groused.

True to the dragon's sense of timing, Barb had the meal prepared in a matter of minutes. As she walked out one of the bowls was caught in a lavender aura and floated over to the stallion buried in books.

"Thanks Barb."

Barb took a seat on the other side of the table, swirling the contents of the bowl. "Dusk, do you remember what Prince Solaris keeps saying?"

"Uh huh."

"What is it then?"

"Uh huh."

Barb blinked, then grinned. "Are you physically attracted to Blitz?"

"Uh hu- Wait, no!"

Barb fell of her seat in a fit of laughter.

"Oh, you think that's funny, huh?" Dusk grinned evilly. "Well, I'm sure you wouldn't mind if I showed Elusive your personal diary, huh?"

Barb froze. "You wouldn't dare."

"Oh, I would. After all, I wouldn't do threaten to do so if I didn't know that you'd written poems on his looks and that one imaginative piece where he screws you."

Barb gasped. "You read my diary?!"

"Uh huh."

The dragon stammered. "You jerk! That contains all of my personal secrets!"

"Like how much you don't like Prince Artemis, and Prince Solaris's beard."

"I can explain the beard." Barb replied. "And Artemis is scary."

"I see. Well, just keep in mind that I don't like you insulting my sexuality, or else it's your diary in Elusive's hands."

"Fine..." Barb crossed her arms. "Uh... How much did you read?"

"I just skimmed over it."

"So you read the entire thing once."

"Noooooooyeah, I read it once, skipping the bits I didn't want to read, like you hypothesising how big Elusive's-"

"TMI! TMI!" Barb waved her arms about. "Owlowicious doesn't need to know!"

"Hoo."

"Oh very well." Dusk snapped the book in his hands shut and placed to his side before picking up his dinner.

"I might as well mention this, but I read your diary."

"Uh huh."

"Very... Vivid description on what Little Mac's vagina looks like."

Dusk blushed. "That was in my personal research journal?"

"Apparently."

"Anything else that shouldn't be there?"

"If you mean 'detailed descriptions of all the cute mare's parts' then no."

"Thank Solaris..."

"However, there was an interesting article on your hypothesis on how female ejaculation works."

"That's supposed to be there."

Barb blinked. "Seriously?"

"It's a hypothesis that relates to my personal interests, and therefore it goes in my personal research journal." Dusk replied matter-of-factly.

"Uh huh, sure." Barb wolfed down her food. "Hey, what do ya know on dragon reproduction?"

Dusk looked up from his food. "Why do you ask?"

"Just curious."

"Well, in terms of having offspring, I believe a male impregnates a female, who then lays eggs. When the temperature and time is right they hatch."

"Anything else?"

"Well, other than records of the possibility of young dragons being able to reproduce with a pony, which ends up with ponies with some dragon features, then nothing else."

"I already knew that bit."

"So I read. After all, you were describing your hypothesised offspring with Elusive, so you must know."

"Dude, shut up about my diary."

"At least they weren't all called Elusive or Barbara."

"I like the name Rarity, so I thought it'd be good-" She shook her head. "Wait a minute, I told you to stop talking about my diary!"

"Sorry."

Barb stood up. "Anything else you know about dragon mating?"

"I know their genitals are hidden under their scales." Dusk finished his dinner. "I had a good example."

"Who?"

Dusk looked at Barb.

It took a few moments for her to get it, but when she did she blushed brightly. "You watched me masturbate?! What kind of sick-!"

The door opened. Standing in the doorway was a sharply-dressed unicorn stallion with a purple mane. "Dusk, are you here?"

"Yes." Dusk replied, looking up. "Hello Elusive."

"Hello Du-"

"HaiElusivewowthat'sanicesuityoulookreallygoodinit!" Barb blurted out, running up and looking over the unicorn.

"Hello Barb." Elusive smiled, nearly making Barb faint. "How are you?"

"Awesome~"

"That's wonderful to hear." Elusive playfully stroked one of Barb's spines, making the drake freeze with a growing blush. "Dusk, do you have a book on 9th century fashions? I feel like the style is going to be coming in and I want to be ready."

Dusk nodded, grabbing several books from the shelves and floating them over. "Get these back as soon as possible, ok?"

"I shall with the upmost haste." Elusive performed a courteous bow before he scooped the floating books up in a magic aura. "See you at a later time, Dusk." He leant over and planted a light kiss on Barb's forehead. "Adieu, Barbara."

Barb watched him as he left, waving pathetically. "Bye..." The door shut in an aura of lavender.

Dusk let out a low whistle. "You lucky girl."

"Dusk," Barb turned to face the unicorn. "I'm going to be in our room. If you so much as think about entering without my permission I will gut you where you stand."

"Barb, wash your forehead."

"Never!" Barb hissed, climbing up the wall.

"Barb."

Barb hissed.

"Barb, you're being disgusting."

"And you're being anal-retentive, so what?"

"Do you think Elusive would like to see you like that?"

Barb paused. "Maybe..."

"If you think I'm anal-retentive, Elusive is off the chart."

Barb sighed, leaping down off the bookshelf. "Do what you must."

Dusk wiped a cloth over her forehead, clearing it of the dirt and sweat that had accumulated over time. "There."

"I'm not happy about it, but I guess I can't wait for when I next shed my skin."

"When is that, anyway?"

"A few years."

Dusk facepalmed. "Really? You weren't going to clean your forehead for three years?"

"That was the plan, which only now do I realise how stupid it was." She blinked. "On an unrelated note, I found this near the door." She pulled out a piece of paper and handed it to Dusk. "It's yours."

Dusk scanned the document: A vivid and highly complicated description of Honeycomb's nether regions. "Can't be."

"Dude, you're the only pony I know to describe inner lips-"

"Labia minor."

"- In lengths up to seven decimal places. In millimetres."

"You still sure?"

"Nopony writes in millimetres unless it's a scientific report!" Barb countered, before sighing and dragging her claw down her face. "Dude, we need to get you a fillyfriend."

"We do?"

"Yeah, otherwise you'll spend half of your life writing scientific reports on the imaginative diameters of random girls' vaginas."

Dusk thought for a moment. "You make a compelling argument, but I can't find any girls that I like."

"Little Mac?"

"Ok, maybe one. But I need to get some confidence, or I could-"

"Tear the town in half in a panicked rage?"

"Exactly." Dusk took a seat. "How does one go about asking someone out?"

Barb swatted a book that was floating up to Dusk out of the air. "From some of my friend's experiences, you basically tell them you're going somewhere and ask if they want to come with. Helps a lot if you have a something to begin with."

Dusk tapped his chin. "That makes sense. I still need to work up the nerve, though."

Barb sat next to him. "That's something you have to do on your own." She crossed her arms. "I still need to get the confidence for asking Elusive out myself."

"How can I tell if Little Mac likes me or not, anyway?"

"Just be yourself, and you should be fine."

"Also," Dusk mused. "How can I be good in bed?"

Barb stammered. "Dude, don't think so far ahead!"

"I can't help it." Dusk adopted a serious, wide-eyed look. "I can't stop thinking."

"Look, if it's bothering you that much, I'll..." Barb took a deep breath. "I'll help you."

"How?"

Barb stood up in front of Dusk and crossed her arms. "Your options are either we fuck, or you sit in your room reading the Kama Sutra for weeks on end."

Dusk blushed. "Well, some first-hand experience would be good, but..."

"I'll let you take notes and use the Kama Sutra as a guide." Barb added with a lack of enthusiasm. She reached for a blank book and a well-worn copy of the Kama Sutra, and handed them to Dusk. She sat in his lap, wrapping her scaly arms around his back. "First and foremost, I'm a dragon and not a pony. And I don't think like Little Mac either, so what works for me might not for her."

Dusk jotted down in the journal. "You're not a pony or Little Mac. Got it."

Barb planted a kiss on his lips, pulling herself closer to Dusk's body. The two continued their kiss, which rapidly became a tongue kiss, before Barb broke off, sliding down his body so that she was kneeling in front of him. "Now, if a girl offers to suck or jack you off, let her unless you have a valid medical reason." She ran her hand along the bulge in Dusk's trousers before gripping the edge and pulling down. The member flicked out, striking her nose.

"Are you alright?"

"Fine." She looked at the object in front of her. "Alright, here goes." She licked the tip a few times before placing it in her mouth, wrapping her long tongue around it. As she pushed herself down her tongue writhed around it, lathering it in her saliva and smoothing the path down to the base. Her nose hit Dusk and she pulled back up, building a strong rhythm.

"B-Barb, I'm..." He grunted, holding her head down, as he reached climax. Hot seed poured out of his member and down her throat, and after a moment he fell limp.

Barb pulled his cock out and coughed. "Gotta be a bit more careful, but otherwise not bad. Now, it's your turn." She pulled herself up and spread her legs, rubbing her claw over her crotch, her breathing heavy. "Just gotta..." A gap in the scales opened up, revealing an oddly-shaped slit. It was sort-of sideways, but the notable features from his various books were in their normal places. At the same time, the scales opened on her breasts and revealed a pair of nipples.

Dusk leant closer, studying it like a book. "So... This is your vaginal entrance..." He prodded the opening. "Your urethra..." Poke.

"Hey, careful."

"This nub here is your clitoris, I believe." He poked her clit, sending a jolt of pleasure up her body.

"Yeah..."

He prodded his fingers at her entrance again before sticking his middle one in. Barb sighed with pleasure as he pulled it out and pushed it back in, starting a rhythm. "Are you enjoying this?"

"Mmhmm..." One of her claws worked their way down to her clit and started circling it. Her breathing picked up and she closed her eyes. "Oh Solaris..." After a minute Barb grabbed Dusk's hand and pulled it out.

"You alright, Barb?"

"Don't wanna come yet." She stood up, still stroking her clit and one of her breasts. She leant over the table, her rear in the air, slit dripping. "Now here comes the fun part."

Dusk stood up and positioned himself behind her, prodding his member at her entrance. "Let me know if I'm being too rough."

"Got it."

He placed his hands on her hips and pushed himself in slowly, the two of them gasping. Dusk quickly established a rhythm, and each thrust was accompanied by a noise from the dragon. Dusk let go of her hips and continued his pace, using his free hands to continue his writing.

After some time, though, his pace dropped. Barb looked behind her in confusion. "Something wrong?"

"Just... Tired..."

"Alright, let's swap." Barb stood up and pulled Dusk out, guiding him to lie on the couch. Once he was settled she sat on top of him and slid his member back inside, starting a rhythm. "Just enjoy yourself."

Dusk nodded, leaning back. "Show me what you've got."

Barb grinned, quickening her pace. As she slammed her hips against his she threw her head back, moaning and panting. She pulled herself forwards, opening her eyes to look straight into Dusk's.

Dusk, however, was solving a rubix cube.

Barb froze, sitting up. "Dusk, what the fuck?" She slapped the rubix cube out of his hands. "Dude, we're having sex! Why the heck are you solving a rubix cube?"

"I-I'm trying to keep my mind sharp."

"The whole point of sex is not to have a sharp mind! You're supposed to let your mind step back and let your body have fun!" Barb crossed her arms. "If you did that to someone else they might think you don't care for them, and in this situation that's the worst possible thing."

"Oh." Dusk grinned sheepishly

"'Oh' is right, jerk." She picked up her pace. "I'll forgive you this time, but if I catch you solving it again I'll break it in half, capice?"

"Understood."

Barb continued her rhythm, her natural dragon constitution doing wonders. After a few moments her breathing got deeper and her moans became louder as she felt climax approaching. "D-Dusk... I'm nearly there..."

"S-same..." Dusk panted. "In or out?"

"In~" Barb moaned, her pace tripling. Her breathing became fast and deep, and she threw her head back. "I-I... I'm... Oh Solaris, I'm coming!" She screamed, her hips slamming against his, as a splash of girl-cum pooled over Dusk. She pulled her hips up and slammed them down, followed by another squirt, and then again, just as Dusk hit his climax and seed spurted into her, splashing out and mixing with the dragon's cum.

Barb fell limp on top of Dusk, the two of them breathing heavily. Barb pulled Dusk into a sloppy kiss for a second before continuing to lie on top of him.

"By Artemis..." Dusk mumbled.

"That was awesome..." Barb cooed, curling up closer. "Except for the rubix cube."

Both of their ears twitched at the sound of the door opening. "Dusk? It's me, Elusive!"

Barb looked back to see Elusive looking around. Unfortunately for her, his eyes quickly locked onto them.

Elusive blinked. "Am... I interrupting something?"

Barb blushed, tears forming. In a second she dashed off, running on all fours to the safety of the basement before Dusk or Elusive could stop her.

"Mind explaining what that was all about?" Elusive asked with curiosity.

"Long story short," Dusk started, refitting his clothing. "She was trying to help me with some sexual experience for when I eventually get a girlfriend."

"I see." Elusive stroked his chin. "I can understand why the poor girl's distressed. The pony she has fallen in love with has walked in on her having intercourse with her best friend of the same gender as her love interest. If I were in her position I'd do much the same."

"Likewise." He turned to face Elusive. "So, what brings you here?"

"Two reasons. One, I'm here to return the books I borrowed. Two, I..." He looked around nervously. "I was going to ask Barb out to see a movie this weekend."

"You... What?" Dusk raised an eyebrow.

"It took me a while to figure out, but Barbara is a pretty charming girl." He blushed a little. "That and her body is very well-proportioned." He struck a dramatic pose. "But alas, it will never work out due to this completely unprecedented circumstance!"

"Dude, relax. This is Barb we're talking about. If you just go up, apologise, and ask her out, you'll be in the green."

"I... I guess you're right." Elusive started walking towards where Barb had dashed off.

"Barb?" Elusive's voice carried through the basement. "Barbara, are you here?"

The sound of crying answered him. He continued down the stairs slowly, one ear tracking the sobbing.

"Barb?" Elusive reached the floor, and saw the dragon curled up in the corner. He approached slowly. "Barb, are you alright?"

Barb curled up more.

"Dusk explained the situation to me, so you have nothing to worry about." He placed a hand on one of the dragon's.

Barb looked up, eyes bloodshot and wet. "R-really?"

"I give you my word, I hold nothing against you."

In one quick move Barb had her arms wrapped around Elusive, sobbing thank-yous and dampening his suit. The smell of sex hit Elusive's nose, no doubt from before.

"Barb..."

The dragon pulled herself back to look Elusive in the eyes. "Yeah...?"

"Would you... do me the honour of accompanying me on a date?"

Barb blinked. Then blinked again. "I have to be dreaming. There's no way you just asked me that."

Elusive chuckled. "I assure you, I'm very real. Feel free to check."

Barb blushed, then leant closer to kiss him. After a moment she pulled back, face as bright as the sun.

Elusive was also blushing. "I guess that's one way of checking."

Barb fainted.

Author's Note

I was writing this story late at night, so the quality may be lacking.

I should have also been doing homework while writing this and the last three... Heh heh... Heh...

The title of this one references Adventure Time (Full title: Adventure Time with Finn and Jake). The (first) genderswap episode of Adventure Time is titled 'Adventure Time with Fionna and Cake', and I decided to play with that name for this Genderswapped story, hence 'Sexy Time with Dusk and Barb'.

There's more: In 'Fionna and Cake', Finn's genderswapped self, Fionna, is shown to be older than Finn actually is. This is similar to how Barb, the genderswapped Spike, in 'Sexy Time with Dusk and Barb' is older than Spike actually is.

Lastly, Barb sings a version of the Adventure Time theme at the start, while she is cooking.

If it wasn't obvious, I'm a huge fan of Adventure Time.
