Twilight angrily groaned as she snapped, yet another, book shut. This was the fourth one she had read this afternoon, but still no results. Every day for the past week she had spent a minimum of six hours studying up on counterspells, trying to see if it had the secret to reversing the spell she had cast on herself and her friends, resulting in them growing cocks. But, no. None of them seemed to have anything that worked on this particular piece of magic. Whoever had designed this spell had meant for it to be permanent. That, or they had never figured out how to reverse it, themselves, and had irresponsibly published it.

There was a knock on her bedroom door, and she straightened herself up, and made sure her cock wasn't visible in the slightest. "Yes?" she called out. There was a twist of the doorknob, and Spike stuck his scaly head inside.

"Hey, Twilight, I was just wondering if it would be okay if I went camping with the Crusaders, tonight."

Twilight smiled at the young drake. "Yeah, that seems okay, just as long as you don't go too close to the Everfree Forest."

"Awesome!" the baby dragon cheered, pumping a fist into the air. "I'll be back sometime tomorrow afternoon. Oh, and don't forget; you have your book club with Cheerilee, tonight."

"Thanks, Spike," she replied, warmly. "But, it's not like you have to remind me about my book club. How could I forget about... my... book club..." she trailed off. She had forgotten about her bimonthly book club. The past week had just been so stressful, what with growing a magically made member. She hadn't even finished reading the book, Chained by Lust, she had been so preoccupied with finding a cure for her cock. That, and she had been masturbating. Like, a lot. So much so, that Spike had grown concerned about why she was being so secretive, and constantly covering her lap, and what that strange smell in her bedroom was.

"Well, I'll be off then. See ya tomorrow!" Spike said, cheerfully waving good bye, as he exited the room.

Twilight checked the clock sitting on her desk. She had about an hour until she had to be at Cheerilee's, which wasn't nearly enough time to quickly read the novel. "Well, I'm sure Cheerilee will understand that I was busy," she sighed. "She should be able to fill me in on the details."

...

An hour later, Twilight was knocking on Cheerilee's front door, her copy of Chained by Lust held in one hand, her other adjusting her pleated skirt so that it couldn't possibly hint at the bulge hidden underneath.

The door swung open to reveal the smiling, fuchsia face of Ponyville's resident schoolteacher, Cheerilee. "Twilight!" she exclaimed. "You're right on time for our little book club. Come on in!"

To call it a "book club" would have been a bit of an exaggeration. Twilight and Cheerilee were the only members, and it was less of a time spent discussing books, and more so a few minutes spent talking about whatever book they read, drinking a little bit too much wine, talking about whatever was going on in their lives, and then picking another book to read over the next two weeks. And, to be honest, Twilight had developed a little, itty-bitty, teeny-tiny crush on the other mare. In fact, the reason why she had suggested something as trashy, vulgar, and pornographic as Chained by Lust by Midnight Silk was an excuse to try and steer the topic of discussion that night into sex and relationships, and maybe lead into... something else.

The two mares were seated on Cheerilee's couch, each clutching a glass of red wine. "So, what did you think of the book?" Cheerilee asked, taking a sip of her drink.

Twilight blushed. "To be honest, I didn't get an opportunity to finish it," she said, sheepishly. "I've been busy the past week with... some research I needed to do that I can't discuss at the moment."

"Oh, that's a shame," Cheerilee said with a frown, taking another sip. "Though, to be quite frank, the book wasn't that great. How far did you get?"

"I had just gotten to the part where Pen Scribe was beginning to question her sexuality," Twilight said, with a blush. Sort of like what's been happening to me, since I started spending time with you, she thought.

"Ooh," Cheerilee squealed. "That's probably the only good part in it. The sex scenes between her and Prince Silver Lining were so drab and lacked passion, but when things got going between her and Feather Duster, that's when things really got exciting." She took another sip of her wine. "And, to be honest, despite the fact that in the "About the Author" section it says Midnight Silk is happily married to her husband, I can't help but feel that she has a preference for the fairer sex."

Oh, I know how that feels, Twilight thought. "So, how were the actual sex scenes between Pen Scribe and Feather Duster?"

"Oh, they were just so passionate! At one point, things got so rough that Feather Duster's wings got pulled a little too hard, causing her feathers to get thrown into disarray, and Pen Scribe tenderly preened her. It was so erotic, yet so romantic!" At the point, Twilight noticed that Cheerilee had been running her fingers through her her own feathers. Cheerilee also noticed this, and quickly yanked her hand back with a blush. "Sorry," she apologized. "I may have had a glass of wine, or two, before you arrived."

"It's quite all right," Twilight said with a reassuring smile. "In fact, it felt pretty nice. I wouldn't mind if you continued. That is, if you wanted to." Twilight felt her face burning up.

Cheerilee smirked. "My, my," she said with half-lidded eyes. "Perhaps Midnight Silk and Pen Scribe aren't the only ones coming to terms with their sexualities." She moved closer, resuming her gentle caress of Twilight's feathers. "Tell me, Twilight; was there perhaps an ulterior motive behind your selection of this meeting's book? Did you, maybe, wish to confess something? I know I'm a few years older than you, and my age is starting to show, but I'm not that much older that it would be weird."

"I-I don't know what you're talking about," Twilight lied, her face glowing a bright scarlet. She turned away and drained the rest of her wine glass.

Cheerilee persisted. "Oh, come on," she said. Her hands were now moving from Twilight's wings, and around to her front, gently brushing her breasts through her sweater vest. "It can't be a coincidence that of all the erotic novels in Equestria, you pick one with steamy, mare-on-mare action." She leaned in closer, her breath tickling the nape of Twilight's neck. "I certainly learned a thing, or two, from this book. Things I wouldn't mind trying with a beautiful, slightly younger alicorn," she said, nibbling Twilight's neck.

Twilight felt something stirring. Oh, no! she thought. Her cock was beginning to harden, slowly pitching a tent in her skirt.

Cheerilee also took notice of Twilight's awkward arousal. "Oh, my," she gasped. "Twilight! I would never have guessed that you were..." she cleared her throat. "Well, I guess it is certainly a good thing that I would never have guessed."

What exactly is Cheerilee implying, here? Twilight wondered. Then, it hit her like a certain mailmare losing focus during her deliveries. Oooohhh. She thinks that I'm- If Twilight's blush could have gotten any darker, it would have. "Oh, no!" she exclaimed. "No no no no! I was born a mare!" she explained. "You see, there's this certain spell that causes a mare to grow a penis, and last week my friends and I sort of decided it might be fun to try it out, and by the time we realized there wasn't a counterspell, it was too late! That's why I didn't finish the book!"

"Oh," Cheerilee sighed in relief. "For a second there, I thought that you were... well, that certainly would have been an awkward conversation to have." Then her expression changed. Twilight thought that Cheerilee looked hurt. "When you said "my friends and I", does that mean you all... had sex? Was I reading your signals wrong?"

"Cheerilee," Twilight said, taking the other mare's hand in her own. "What happened with my friends and I was something that just happened in the heat of the moment. It was just... casual sex, I guess. It meant nothing. As for you "reading my signals"," Twilight steeled herself for what she was about to do, before lunging forward and meeting Cheerilee in a kiss. She wrapped her arms and wings around the older mare, and Cheerilee reciprocated the affection, running her fingers through Twilight's mane. After what must have been several minutes of passionate kissing (both mares had lost track of time), the two pulled themselves apart, panting, a string of spit connecting the two. "Does that answer your question?"

Cheerilee giggled. "My, how forward of you," she said, planting another brief kiss on Twilight's lips. She reached down and grasped Twilight's dick through her skirt, stroking it through the fabric. "Would it be all right if I took a look?" she whispered. Twilight nodded. With a smile, Cheerilee grabbed the waistband of Twilight's skirt and pulled it down, revealing her plain panties.

"I'm sorry my underwear isn't, you know, sexier." The alicorn said, sheepishly.

"Don't worry about that. I think they're quite cute," the older mare said, nuzzling the bulge trapped within the white, cotton confines. "Besides, I'm more interested in what's inside," she continued, pulling the undergarment down, joining the skirt on the floor. Twilight's boner bounced as it was freed from its prison, a drop of pre already oozing from the tip. Cheerilee leaned forward, and planted a kiss on the head, licking up the salty slime.

"L-lee," Twilight moaned as the schoolteacher licked up and down her length, slurping up the pre that dribbled out. She moved her mouth away from the purple pecker, and softly stroked it, planting the occasional kiss along the shaft.

She moved downward, smothering Twilight's balls in kisses. She pressed her muzzle into the scrotum and inhaled, deeply. "These smell lovely, Twilight," Cheerilee said, rubbing the heavy sack in your face. "They smell of the most arousing musk and, oh, what type of soap do you use? Is that vanilla?" Twilight nodded, her eyes shut tight in bliss. Cheerilee sucked one of the large testicles into her mouth, slathering it in saliva, and rolling it around with her tongue.

Cheerilee pulled away. With one single motion, she pulled off her white t-shirt and threw it across the room, her bra following soon after. She grabbed her B-cup breasts in each hand, and brought them to Twilight's dick. She wrapped her soft tits around Twilight's hard cock, lightly massaging the prick. "How do you like this, Twilight?" she asked, lightly breathing on Twilight's cock, earning another throb and glob of precum. "How do you like my tits? Do like to feel them smooshed around this beautiful cock of yours?"

"Oh, Lee," Twilight moaned, thrusting into the mulberry mammaries. "I love your boobs and I love fucking them!" She let out another moan and the rate of her thrusting increased. "I'm gonna cum!" But, before the purple princess could achieve her orgasm, Cheerilee pulled away. Twilight groaned, humping into the air. Her release had been denied. "W-why?" Twilight groaned. "Why did you stop?"

"Because," Cheerilee said, smirking. She lightly rubbed a teasing finger along the royal scepter. "I want this to last," she continued, planting a small kiss along the shaft. "And, it will feel so much better when I finally do let you cum. Now, let's get these off." She pulled off Twilight's sweater vest, and then unbuttoned her blouse, revealing a plain bra that matched her panties. She drew Twilight in for another kiss, happily playing with the alicorn's tongue, as she nimbly unhooked her bra, letting Twilight's C-cup boobs breathe.

Cheerilee pulled away, before lunging forward, burying her face into Twilight's cleavage. She kissed and licked every inch that her muzzle could reach. She moved towards a dark, purple areola, and gently nibbled it. Twilight screamed in bliss. Cheerilee's teasing was driving her wild, her cock throbbed, dribbling slick, slimy pre, staining the sofa she was seated on.

"Cheerilee! Please!" the princess gasped. "Stop teasing me!"

Cheerilee laughed. "Well, because you asked so nicely," she said, moving her mouth to suckle Twilight's other nipple, one hand squeezing the breast her moist mouth had just abandoned, her other hand dropping down, jerking Twilight's well lubricated dick. Twilight eagerly thrust her hips in time with Cheerilee's handjob.

Cheerilee pulled herself away from Twilight's bust, giving each boob one last kiss and nibble, before moving downwards, peppering Twilight's tummy with smooches, before returning to the alicorn's glorious dong. She planted a quick peck on the glans, then began to lick up and down the shaft, collecting the tasty treat that coated the cock. Once she had collected all of the pre in her mouth, she looked up at her lover, giving her a wide, open mouthed smile, showing off what had she had earned. It was easily a mouthful, slightly bigger than what the average stallion produced in a single ejaculation, and Twilight hadn't even properly came, yet! She let out a short giggle, and gargled the salty slime, before she lowered her mouth back down to Twilight's extensive erection, and drooled the preejaculate back where it had been. Opening her jaw, wide, she slurped Twilight's cock into her mouth, resuming her blowjob from earlier.

Cheerilee heard the familiar tingle of magic, and felt her lower body being lifted from the floor, her rump rotating so that they were now in a seated sixty-nine position. There was another flash of magic, and a cool breeze on her nethers told Cheerilee that her pants had been removed, and, sure enough, from the corner of her eye she could see her jeans and panties neatly folded on the coffee table.

"Oh my!" Cheerille gasped, the cock she had been servicing sliding from her throat, as Twilight's talented tongue lapped at Cheerilee's labia. Her pussy had been wet, earlier, but now she was leaking under Twilight's stimulation. She resumed her blowjob, but under the additional attention she was receiving, her sucking and slurping became sloppier, less focused.

With a scream, Cheerilee came, cock still lodged in her throat, showering Twilight with her juices. The tightening and vibrations of the earth pony's throat muscles sent Twilight over the edge, as well, her cock throbbing and erupting right into Cheerilee's esophagus. Twilight continued to lick, kiss, and suck Cheerilee's cunt, drawing out the older mare's orgasm, while Cheerilee did her best to swallow all of the creamy cum being pumped into her stomach, but to no avail. She ended up coughing up most of Twilight's spunk, the goo dripping down her forehead. When their euphorias finally subsided, Twilight's upper body was drenched in Cheerilee's marecum, while Cheerilee's entire face and most of her mane were painted white.

"Twilight," Ceerilee panted, wiping cum from her eyes, which she had thankfully closed in time, as to not be blind by sperm. "Could you please put me down? I'm starting to get a headache." Twilight complied, using her magic to flip the schoolteacher right side up, sitting her down on the princess' lap. Cheerilee grabbed Twilight by the back of her head, drawing her into another fierce makeout session. The two mares could taste their cum in their partners' mouths, savoring the way their flavors mixed.

"Nopony has ever made me cum like that," Cheerilee gasped, pulling away from the kiss, before diving in for more. "Here's what's going to happen, now," she continued, wiping some of the cum from her face and licking some of it up, before sticking her fingers in Twilight's mouth for her to taste the rest of what she had gathered. "You and I are going to put your clothes in the wash, quickly take a bath to clean ourselves up- and only to clean ourselves up!- then, we will get dressed, and go have a nice, candlelit dinner at Nous crachons dans votre nourriture, maybe get some ice cream, afterwards, then we will come back here, watch a movie, and then go to bed."

"And what are we going to do on the bed?" Twilight asked, coyly, licking up the last of her cum from Cheerilee's fingers.

Cheerilee only laughed, before pulling Twilight in for another kiss.

Author's Note

Really surprised at how fast I'm pumping these chapters out. Usually, I get writer's block shortly after publishing something, but I am riding this creative high.
