Advanced Anatomy, by Twilight Sparkle

“I can’t believe that!” Twilight buried her face in one of the couch cushions, wishing she could put her shame in there with it. “See muff miiite mare!”

“It’s okay… right?” Sonata patted her head. “I mean, I think it is. I can’t tell what you’re saying.”

“See muff-aaah~!” Twilight raised her head with a gasp, face flushed beet-red as she clutched the pillow to her chest. “-right there! Sunset! Watching! What do I do?”

Sonata looked back at the empty doorway and cocked her head in confusion. “Well, she’s not here now. What’s it matter?”

“What’s it matter?! She saw us and now… and now... Oh my-” Twilight rambled until she was cut off by a kiss.

Sonata broke away and rubbed Twilight's thigh lightly. “It’s okay. Sunset won’t judge you, why would she? I mean, it was Adagio’s idea which practically makes Sunset responsible.”

Twilight shook her head rapidly to clear her thoughts, looking down and placed her hand over Sonata's, resting on her thigh. “Thank you. I’m... sorry we didn’t finish, I know you were close too,” she said, hiding her blush with the cushion.

“We can always try again, if you’d like to. Head to the bedroom, and lock the door if you feel up to it? I mean, that was cray-zee!” Sonata prattled on a little herself, looking anywhere but at Twilight. It was oddly calming.

“Yes,” Twilight said, “we can.”

“W-what?” Sonata squeaked. “Like, now, really?”

Twilight nodded and got up, brushing her fingers across Sonata’s chest as she went.

She took a few steps away, then looked back and blushed as she beckoned. “Come with me? We... we should finish this in the bedroom.”

Sonata watched as Twilight vanished down the hall, realizing with a start she was being left behind. She made off to the bedroom just in time to see Twilight carefully smooth the bedsheets and climb on top.

“L-lock the door, this time.”

The bolt slid home with a loud “click,” echoing slightly in the silent house.

Sonata licked her lips in anticipation as she watched Twilight with hungry eyes, her hips swaying with each step she took. She leaned forward, giving Twilight a beautiful view of her breasts as she rested her hands on either side of Twilight’s legs, face to face but not quite touching.

“And what are we gonna do on the bed, Miss Sexy Librarian?”

That was just a bit too much for Twilight at that moment, as she was still preoccupied with the novelty of having a gorgeous girl right there.

“I-I…” She squeaked, her heartbeat hammering in her chest, “oh yes… uh...well I think...we should help you reach your...uh… orgasm.”

Twilight struggled not to cave under the pressure and lay back, Sonata climbing up over her. Sonata was in charge now. Sonata was towering over her.

She didn’t really expect Sonata to blush and look away. “No seriously, what now?”

“Well it’s your turn so…” Twilight blushed, and ran her fingertips over Sonata’s hardened nipples, earning her a gasp.

Sonata watched carefully, biting her lip to cover her grin.

Twilight's hand shook slightly as she moved her fingers up and down Sonata’s body. Her hand becoming more confident at each reaction she got as she traced light shapes into the warm skin above her.

Low moans and gasps began as she moved back up to her nipples and pinched them between her thumb and and pointer finger.

Sonata gripped the sheets underneath her hands and she dipped her head into Twilight's neck, biting down hard as she moaned. Steadying herself, she placed a hand over Twilight’s lower lips, about to enter the girl beneath her when Twilight stopped.

That was unacceptable. She was the one in charge.

Twilight lifted her arm, knocking Sonata’s support out from underneath her and pulling her close at the same time she slid her other hand up between Sonata’s legs with a light slap.

Sonata yelped at the shock. “W-woah, there!”

“You.” Twilight growled, rolling them over so she was on top. “Are… are not.” She kissed her aggressively, punctuating each word with a peck. “Allowed. To. Do. That. Yet. I’m teaching you.”

She finished the lecture with a light nibble to Sonata’s lip, working her palm in quick circles along her crotch the whole time. Sonata just clung to her, breath becoming ragged. Her smooth legs slid up Twilight’s until they were wrapped loosely as Sonata melted from her ministrations.

Twilight leaned in, pressing harder as she breathed in Sonata’s ear. “Are your ready?”

“R-ready… for… wh-HAAAAAA~!” Sonata gasped as Twilight shifted her grip down below, bringing her fingertips to bear as she moved as fast as she could.

“Oh! OOOOH! Oh that’s… what is… am I…? Ah… AAAAAAH!”

“You’re cumming,” Twilight explained, sighing in her ear, “and I haven’t even gone in yet~”

Which was when Twilight slid her middle finger down and right into Sonata’s sensitive insides.

Sonata’s back arched as she stopped moving, arms and legs holding Twilight as tight as she could. Her eyes rolled back, mouth open in a soundless cry as Twilight watched, keeping only slight pressure as she took in the view, half-concerned and entirely aroused.

“You okay?” Twilight asked as Sonata finally drew a deep breath.

“Y-yeah. Wow. Do that…. Do that again!” Sonata said between breaths, pulling at the skin on Twilight’s back with her fingertips.

Twilight raised an eyebrow, choosing to take that statement very literally. “Ok.”

She slid her index finger in as well. Then she spread them.

Sonata wailed, letting go of Twilight to claw at the bedsheets. She was cuming again, but this time Twilight wasn’t done. She twisted her hand, putting her thumb over Sonata’s clitoris as she worked her fingers along the slick walls. Sonata seized around her again and again as Twilight sat up to watch, pulsing her hand in and out, still held tight by Sonata’s legs. She could see her abs tense in perfect definition every time she came, and the delicate muscles in her neck and arms writhed as Sonata alternately cried and gasped.

She gave her a break when Sonata’s voice cracked and she squeezed so tight it hurt Twilight’s fingers. Twilight pulled them out and went back to rubbing her whole crotch, gently this time.

“There…” Twilight whispered, laying back down with her and disentangling herself from Sonata’s legs, sliding her own in-between to rub their thighs together. “How was that?”

Sonata’s chest heaved as she tried to catch her breath, blinking away stars. Every muscle in her body was strained and quivering. She wanted to tell Twilight how amazing that was. She had to. Twilight had to know what she had just done.

She couldn't even speak. Not right then.

First the room had to stop spinning.

“I... think I pulled something,” Sonata croaked weakly after a while. Not what she had meant to say. Twilight giggled before immediately becoming concerned.

“Wait really? Are you… are you ok? Do I need to take you-” Twilight was silenced by Sonata’s fingers on her lips.

“Sssssshush…” Sonata soothed, eyes closed. She slid her hand down to Twilight’s neck, and Twilight could smell herself soaked into them. “You next,” Sonata said arily, still dazed.

“L-let me get you some help for that then.” Twilight pushed herself away, lunging for the stand on the far side of the bed.

“What are you getting?” Sonata asked, lifting her head barely enough to see Twilight holding a slim black bag with a purple star.

“Something to help, I promise,” Twilight purred, climbing onto the bed and opening the bag, “are your muscles ok to sit up?”

Sonata shifted slightly and nods, sliding slowly into a sitting position, back against the headboard, groaning softly from her slightly sore muscles. “Alright, what now?” she asked.

Twilight crawled over Sonata’s left leg, settling her rear flush against Sonata’s crotch and leaned back. She smiled as she grabbed the siren’s hand in hers and brought it towards the open bag.

“Here,” she purred as she let Sonata’s hand go so she could reach into it.

Sonata hummed in confusion as she felt into the bag and pulled out a remote along with a rather graphically detailed rod. “W-what’s this do? And why do you have a dick in a bag?” she asked as she took out a small purple dildo.

“It’s a vibrator, the remote control’s it’s speed,” Twilight giggled, wrapping Sonata’s fingers around it, “and you’re going to use it on me.”

She smiled and layed her head back on Sonata’s shoulder as she spread her labia with one hand and stroked her soaking clit. Twilight purred softly as she guided the vibrator in Sonata’s hand down to her crotch and her breathing became heavier as it entered her. “Touch the top button once, that’ll-mmm~ turn it on the lowest speed. It goes to five and then turns off.”

Sonata looked at the remote in her hand unsurely, but decided to give it a try and pressed her thumb lightly onto the button as she was told, earning her a low moan. She looked over and watched as Twilight’s eyes closed and her hand loosened from Sonata’s as the vibrator pumped in and out of her nethers slowly. Her confidence grew and she turned the speed up on the vibrator, thrusting it faster.

Twilight gasped in surprise at the sudden change in sensation and the quickening pace, her moans growing ever more noticeable. She let her hands drift away from Sonata’s and she gripped the hips underneath hers.

Sonata gasped herself as she felt nails digging into her hips and she dipped her head, biting into Twilight’s neck, hard.

“mmMMM~! Gah! You’re getting good at this a-already,” Twilight moaned, her chest heaving with every thrust. “You can go h-harder.”

Sonata kissed the bite mark lightly, and purred softly into the nape of her neck. “Mmm... alrighty.”

Twilight’s moans became louder as her hips bucked with the hard thrusts, Sonata adding variety with some twisting motion, dropping the remote to get a better grip. Twilight reached her limit far sooner than she had been ready for.

“oooOOOH~ fuck! I-I’m c-cumm-MMM~!” she cried out, turning to muffle her scream in Sonata's neck. “I-I get why this looked like.... oooh wrestling~!”

“I know, right?” Sonata giggled, wrapping her free arm up under Twilight’s, digging her fingers into Twilight’s hair in a pseudo-half-Nelson to pull her back further onto the bed. Twilight melted in her grip as Sonata slid the vibrator as far as it would go.

“Wait a second…” Sonata let go, letting Twilight fall off of her with a groan, leaving the toy buried inside her. Twilight raised her head weakly, just in time to see Sonata recover the remote from the folds in the sheets. “That’s two. Didn’t you say this goes to five?”

Twilight wailed as the vibrator leapt to maximum speed, clenching her legs together and curling into a ball on the bed as her insides writhed in pleasure. Sonata purred with delight, tossing aside the remote as she pounced on her, reaching down to hold the wildly pulsing toy in.

Gasping and bucking as her body fought between trying to escape and wanting more, Twilight reached around behind her and sought out Sonata’s vagaina, still slick from her last attempt. She didn’t have any fine control as she scrabbled for purchase, shuddering as Sonata stroked and squeezed everything she could reach. She found her grip as her middle two fingers slid blindly in.

Sonata squeezed Twilight’s breast tighter, groaning along with her as Twilight curled her hand inside her in response. She tugged at the vibrator, barely able to hold on as Twilight’s thick juices made it slick. She adjusted her grip so her finger could reach Twilight’s clit, letting it channel the vibrations as Twilight’s fingering became faster, rougher, and more desperate.

Twilight cried out as the trembling hit just the right spot, and she arched her back. Her body ached from every bit of pleasure Sonata gave her, and she scrambled to bring Sonata closer to her own orgasm.

Sonata moaned lowly as Twilight’s fingers constantly rubbed against her upper inner wall.

“Oh, you are amazing, this is a-amazing!” Sonata shouted as the feelings of pleasure rose in her body, her eyes screwed shut. “mmmmMMM~! O-ooooooh~! I-I’m right theraaaaaaaaaAAAAH~!”

She cried out as Twilight added a third finger, pushing in as deep as her hand would go. Sonata stiffened, grip slipping and pushing hard on the vibrator as both girls saw stars and the world dissolved around them.

Twilight gasped for breath as she looked back at Sonata, noticing her eyes were hazed over from her own climax. Once they had settled she leaned back into Sonata, panting softly.

“Wow,” she panted out airily, resting her head back against the soft chest behind her.

“That good huh?” Sonata asked, kissing the bite marks she had left as she slowed down her thrusts, letting Twilight recover. “We might have to do this again then, maybe?”

“Oh yes we are doing this again,” Twilight panted, a hand over her chest as she steadied her breathing.

“Make it a date then?” Sonata chuckled, her arms moving to around Twilight’s waist and clasping her hands together over her stomach.

Twilight nodded slightly, leaning into Sonata. “Oh, definitely a yes.”

“Yay!” Sonata sighed with a bright smile.

"You at least owe me dinner for this," Twilight chuckled as she reached back and caressed Sonata’s backside softly.

"Oh? Sure, we can-" Sonata started before she was interrupted.

"Not... tacos."

Sonata pouted, and nuzzled into Twilight’s neck. "Damnit."
