After some time Twilight calmed down and they just lay there for a couple of minutes with Twilight gently nuzzling Rainbow's neck. After a few more minutes Twilight raised herself up, supporting her weight on her elbow. With her other hand she wiped her eyes to clear away the tears and smiled down at Rainbow. Rainbow returned her smile.

"Dashie, I love you so much. I can't believe you still want to be with me," Twilight said.

"Course I do, Twi. You're still the same amazing mare as ever, that hasn't changed," Rainbow said.

"I can't believe we're both lying here together, naked! This is the happiest day of my day life Dashie, you have no idea how good I feel right now," Twilight said with tears coming back to her eyes.

"I think this is probably the second happiest day of my life, the first was when you said yes to going out with me," Rainbow replied with a smile.

Twilight's smile got even bigger and some tears ran down her face as she giggled. "Oh Dashie stop it. If you get any sweeter I'm going to get a sugar rush just from being near you," she said giving Rainbow a squeeze.

Rainbow chuckled as well before responding. "You really are beautiful, Twilight," she said with gentle sincerity.

Twilight reached her hand up to Rainbows face and stroked her cheek gently. "Not as beautiful as you," she whispered before leaning down and kissing Rainbow. For the first time ever, the kiss lasted for more than two seconds, going on for twenty seconds or more. Twilight broke the kiss and looked down into Rainbow's eyes and shivered. "That felt amazing," she said quietly.

"Mmhmm," Rainbow agreed. "I take it from the pressure against my leg that you aren't worried about being aroused around me anymore." Rainbow added with a smile.

Twilight looked confused for half a second before realization dawned on her. "O-oh sorry!" she said sheepishly.

Rainbow chuckled. "It's okay, Twi, it's nothing to be embarrassed about. I'd be lying if I said I wasn't a little aroused myself right now."

"Really?" Twilight asked.

"Okay, more than a little aroused," Rainbow chuckled as Twilight blushed. They stayed there for a minute just looking into each others eyes. Rainbow felt completely at ease with Twilight, and if her expression was anything to go by, Twilight felt comfortable too. Then Twilight got an uneasy look on her face.

"Um, Dashie?"

"Hmm."

"A-as comfortable as I am right now. I-I don't think we should, um, a-advance our relationship any further tonight. Y-you know, s-sexually." Twilight said nervously. Rainbow smiled and brought her hand up to gently cup Twilight's face.

"I understand. You've had a rough day with all this worrying, I know it'd be a bad idea to go any further tonight. It's something we should wait at least a couple days before doing," Rainbow said. "B-but whenever you're ready is fine, no pressure," she hastily added.

Twilight smiled, "Thanks Dashie." Twilight pushed herself off of Dash and sat herself cross-legged on the bed, "but just because we aren't going to have sex tonight doesn't mean we can't prepare a little for it."

"What do you mean Twi?" Rainbow asked with a confused look.

"Well, I'm sure you have questions, and there are some things you should know beforehand," Twilight replied.

Rainbow sat up as well and sat cross-legged on the bed facing Twilight. "Yeah, I guess I'm curious about some things." She reached over and grasped both of Twilight's hands in hers giving them a gentle squeeze.

"Well, ask away!" Twilight said with a smile. "It's important that you have all the information you need and I'm happy to answer anything you want to know. Nothing is too private, not for you," she blushed a little.

"Well okay then, I guess the main thing I'm curious about is, um, does your cock work? Like fully I mean," Rainbow asked a little nervously.

"You mean sexually?" Twilight asked. Rainbow nodded. "Well, um, yes and no." Rainbow cocked her head to the side, Twilight smiled and continued. "You see, I can get erections obviously," she looked down at her semi-erect penis then back up to Rainbow's face. "That's why I was worried about getting aroused around you, but it's difficult to maintain an erection for very long. Also, I can have orgasms, but I don't ejaculate." Twilight said while blushing.

"Really? So, nothing comes out at all?" Rainbow asked.

"Nope, not a thing," Twilight replied. "It's a side-effect of the hormone treatment, the male reproductive system just shuts down. You may have noticed that my testicles are smaller than the average male."

"I hadn't actually," Rainbow replied and then looked down into Twilight's lap. "Oh yeah, so they are." She looked back up to Twilight's blushing face. "So um, yeah, if you have trouble keeping it up, how do you, you know, cum?" Rainbow asked tentatively.

Twilight was blushing like mad, "W-with some difficulty actually. When I, er, masturbate, I don't always climax. In fact probably only about half the time. I-it still feels really good though so I don't mind if I don't get there."

"Oh, that kind of sucks." Rainbow said.

"It's not so bad really. Even when I don't climax, I still feel great after masturbating. I'm sure the same will be true for sex," Twilight said.

Rainbow smiled. "Well okay then, as long as you enjoy it that's all that really matters to me," she said giving Twilight's hands another gentle squeeze.

"So, anything else?" Twilight asked.

"Just one thing, you don't have any pubes, what's up with that?" Rainbow asked.

"Oh that," Twilight giggled. "My Doctor knew a permanent hair removal spell, he used it on my face to stop a beard from growing. Anyway, he offered to use it on, uh, that region in case I ever wanted to tape it down. In the end though I got him to do it everywhere from the neck down."

Rainbow winced a little, "yeah, tape in that area would suck if you had hair. Wait a second, you don't have to shave your legs or armpits or anything?"

Twilight giggled, "Nope, not at all."

"You lucky thing you! I'd love to not have to do that," Rainbow said.

"I'm sure it could be arranged, I bet someone at the Ponyville Hospital knows the spell," Twilight said.

"Yeah, maybe, might look into that," Rainbow replied.

"Anyway, any other questions?" Twilight asked.

"Nah, not right now anyway, might think of other stuff later though," Rainbow replied. "So, what do you want to do now?"

Twilight thought for a moment, then she gasped as her eyes lit up. "I have an idea!" she declared. "Follow me!" Twilight pulled her hands from Rainbow's and jumped off the bed and ran out of the room,

"Where you going, Twi?" Rainbow called after her as she jumped up to follow her.

"Down here!" Twilight called back.

Rainbow went down the stairs into the main room of the library. She saw that Twilight had closed all the curtains in the room. She saw Twilight in the middle of the room with her arms spread wide and spinning in circles while giggling. "What are you doing, Twi?" Rainbow asked with a small smile. Twilight stopped spinning and just as she was about to answer she stumbled, almost falling over. Rainbow quickly ran over to her and steadied her. "Whoa Twi, you alright?"

Twilight giggled some more. "Yeah, just got a bit dizzy there," she replied. "But isn't this great Dashie, I'm naked, in a Library! We're naked in a Library!" she giggled again. "Isn't it exciting! We're naked in a place where people come to get books. A public place! And here we are, naked! I feel so naughty, so free!" She giggled again.

With a huge smile on her face Rainbow hugged Twilight tightly. "Oh Twilight, you're so cute sometimes!" she said while nuzzling the side of Twilight's face. Twilight just giggled some more.

"I've always wanted to do this, be naked in a Library. Just me and the books, nothing else. It felt so wrong to even think about, but so exciting. But now, I have my very sexy marefriend naked with me too. This is so much better than my fantasy." She kissed Rainbow's neck.

"I'm glad you're enjoying yourself, Twi," Rainbow said. "Now that you mention it, it does feel kind of naughty being naked in a public Library. Even if the doors are locked and nobody can see us."

"I know!" Twilight giggled again. She then broke the embrace with Rainbow and darted over to a bookshelf. She grabbed a big old looking book from the shelf and hugged it to her chest. "I've always wanted to do this."

Rainbow looked puzzled "Hug a book?"

"No." Twilight replied. "Well, sort of, I mean hold a book against my naked body." She blushed like mad. "You know, while still being in the Library. Of course I could do this in private, but it's not the same."

"Oh," Rainbow said with a smirk. "So, how is it?"

Twilight frowned. "Not as good as I thought it would be. Certainly not as good as hugging you," she said. She put the book back on the shelf and walked back over to Rainbow and hugged her. "Mmmm, much better."

Rainbow laughed a little. "Well it's good to know I'm more hug-able than a book." Twilight lightly slapped her arm.

"Quiet you," she said playfully. "Of course you're more hug-able than a book, and a lot more desirable too," she added, nuzzling Rainbow's neck. Rainbow gave her a light squeeze.

"Hey, do you think we should get something to eat?" Rainbow asked.

"Hmm?" Twilight looked up the clock on the wall. "Yeah I guess we should, not sure I'm that hungry though."

"Me neither, how about we just make up some sandwiches?" Rainbow suggested.

"Sounds good to me," Twilight smiled.

They entered the kitchen and Twilight set about making daffodil sandwiches and Rainbow sat at the small round table in the middle of the room. Twilight sat a plate with a sandwich on it in front of Rainbow before sitting across from her with a plate of her own. They ate their food in silence occasionally looking into each other eyes before looking back to their sandwiches. When they were done, Twilight levitated the plates over to the sink. She looked at Rainbow and smiled nervously.

"Um, Dashie, I actually have a question of my own," Twilight said quietly.

"Oh, sure thing, shoot!" Rainbow smiled.

"Um, w-what's it feel like?" Twilight asked almost too quietly for Rainbow to hear.

"What? Sex?" Rainbow asked.

"N-no, well yes, kind of," Twilight stuttered. "I-I meant, what does a vagina feel like?" Twilight looked down into her lap and frowning.

Rainbow's eyes widened and her jaw dropped. Oh my gosh, I didn't even think of that! She's never been with a mare and she doesn't have one herself! By Celestia! She's a mare and she doesn't even know what a pussy is like! That's terrible! Rainbow thought.

"That's so not fair," Rainbow said quietly, then she smiled. "Luckily we can fix this little problem."

"Huh?" Twilight looked up at Rainbow.

Rainbow got up and walked around the table, sitting her butt down on the table in front of Twilight. She threw her leg over Twilight's lap so that she had a leg either side of her. She then leaned back resting on her elbows, lifted her legs up and rested her heels on the edge of the table and spreading her knees as far apart as was comfortable. All of this had the effect of putting her vagina on full display to Twilight. Twilight's eyes widened and she gasped, slapping a hand over her mouth.

"R-Rainbow! What are you doing!?" Twilight said through her hand.

Rainbow smirked. "Well, you wanted to see one, there you go."

"I-I know what a vagina looks like! I've seen diagrams! I-I've just never felt one before," Twilight said.

"Oh, right, that makes sense. Well, you can touch it too if you want," Rainbow said.

"W-what!?"

"Well sure, why not?" Rainbow said. "I trust you, and I know you keep your fingernails short so I'm not worried about you accidentally hurting me or anything like that."

"B-but, really?" Twilight asked uncertainly.

"Yeah sure, I get you might be a bit nervous about it though. How about you start by touching around it?" Rainbow asked.

"W-well, okay, I guess." Twilight reached out a shaky hand and slowly approached Rainbows pubic mound. She looked up to Rainbow's face, Rainbow just smiled at her and giving a small nod. Twilight looked down and gently brought her fingers into contact with Rainbow's pubic hair in the area her vagina. She gently brushed the soft hairs with her fingertips. "I-I can't believe your pubic hair is also rainbow colored."

Rainbow laughed. "Yeah, the carpet matches the curtains."

Twilight looked puzzled a moment but then got it. "Oh, so that's what that phrase means. I had wondered."

"Yeah," Rainbow giggled.

Twilight ran her fingers down the side of Rainbow's pubic mound just inside the area of the pubic hair lightly brushing the outer skin of Rainbow's vagina. Getting a bit more brave, she moved her fingers over a little and started rubbing up and down the side of the labia. "I-it's a bit moist," she observed.

"Mmhmm," Rainbow replied. "Keep going, it's okay."

Twilight brought her thumb to the other side of Rainbow's labial lip and lightly pinched it between her thumb and fingers and rubbing her thumb up and down.

"Mmm," Rainbow moaned lightly. Twilight jumped, looking to Rainbow with a panicked look. "It's okay Twi, you're doing good, didn't mean to startle you," Rainbow quickly assured her.

"O-okay," Twilight said. She moved her fingers across to the middle of Rainbows vagina and started rubbing her fingers up and down the middle part of her labia. "Wow, so smooth, so slick," she observed. As she was rubbing her middle finger slid up and accidentally hit Rainbow's clitoris making Rainbow gasp. "Eeep!" Twilight exclaimed, pulling her hand away.

"I-it's alright Twi, you just hit my clit and surprised me, that's very sensitive. Might want to avoid that 'til I'm more turned on." Rainbow smiled.

"O-okay, sorry," Twilight said quietly.

"It's okay Twi, it didn't hurt. It was just a surprise is all," Rainbow said. "Why don't you try going lower," she suggested.

Twilight returned her fingers to the middle of Rainbow's labia and slowly slid them down. Twilight gasped slightly as her middle finger rubbed over the entrance to Rainbow's orifice. "T-that's the entrance isn't it?" she asked.

"Mmhmm," Rainbow replied. Twilight rubbed her middle finger around the outside of the opening, her index and ring fingers rubbing the sides, as she stared almost transfixed. "Mmm, you can put a finger in if you want," Rainbow gently suggested.

Twilight looked up with wide eyes. "Really?"

"Yeah, go for it," Rainbow encouraged.

Twilight gently applied pressure with her middle finger, the entrance yielded easily to such a small intruder. Her finger slipped in up to the first knuckle. Rainbow's muscles clenched lightly grabbing Twilight's finger. "Mmm," Rainbow quietly moaned.

"Oh wow, I didn't know it could grab like that," Twilight said quietly. "I mean, I had read about it but feeling it is amazing."

"Yeah, just imagine how that will feel on your cock," Rainbow said with a smirk.

Twilight blushed heavily and smiled. "Wow," she whispered.

"Mmhmm, keep going Twi, you can get in a lot deeper than that," Rainbow said encouragingly.

"O-okay," Twilight said. She pushed her finger into the second knuckle and again felt the clenching of Rainbow's muscles. "Wow," she said again.

"Mmhmm, hold on a sec, my elbows are getting a bit sore here," Rainbow pulled herself up a bit, brought her arms forward, spread her wings out and then lay flat on the table. She rested her arms on top of her wings. A bit uncomfortable laying on a hard table like this. Oh well, that's what I get for jumping into this so quickly, she thought. "Okay, you can continue now," she said.

"Okay," Twilight replied. She slowly pushed her finger in as deep as it would go, her index and ring fingers lay flat against the sides of Rainbow's vagina.

"Mmm, t-try putting your pointer finger and middle finger in at the same time, and curl up your other fingers out of the way. You should be able to get in a bit deeper that way," Rainbow suggested.

Twilight nodded even though Rainbow couldn't see it as she was staring up at the ceiling. Rainbow gasped a little as Twilight pulled her finger out. She then positioned her hand like Rainbow suggested, then reinserted her middle finger until her index finger touched the outside of the entrance. She then slowly pushed in to her index finger's first knuckle stretching Rainbow's vagina open a bit more.

"Mmm yeah, go deeper," Rainbow encouraged. Twilight pushed in to the second knuckle and Rainbow's muscles clenched again. "Oh yeah, that feels nice, Twi," Rainbow said her breathing getting a bit heavier. Twilight pushed slowly in as far as she could, until the base of her curled up ring finger and little finger were pressed against the side of Rainbow's vagina. Rainbow arched her back a little. "Mmm, yeah."

Twilight got a curious expression on her face. "Hold on, what's this?" she asked. She turned her hand over, twisting her fingers around inside Rainbow so they were facing upward.

"Mmmm," Rainbow moaned in response.

Twilight's fingers started rubbing back and forth on something within Rainbow's vagina. "Oh my gosh, that's your cervix! I'm touching your cervix!" Twilight put her free hand over her mouth, her eyes bulging wide.

"Mmmmm, yeah, so?" Rainbow asked.

"W-well, it's the entrance to your uterus, the part of you that makes new life. I-I just think that's really special," Twilight said, her voice getting quieter near the end.

Rainbow cringed. "I-I'm sorry Twi, I d-didn't mean to make you feel bad." Idiot Dash, she's a mare who can't have foals and you ask her what the big deal is about my uterus. Good one moron.

Twilight shook her head. "N-no no, it's okay, it's not your fault." She gave a small smile. "I just think it's amazing that I'm actually feeling this," she said. Rainbow craned her neck down to look at Twilight and give a small smile in return. "A-anyway, I think I'm done exploring," she added.

Rainbow nodded still smiling a little. Yeah that was a bit of a mood killer, and just when I was starting to enjoy it too. Oh well, she thought.

Twilight removed her fingers from Rainbow's vagina. Rainbow let her feet fall from the table and sat up in front of Twilight. Twilight brought her fingers close to her face and sniffed lightly. "Interesting aroma, kind of musky," she observed. She rubbed her pointer finger and middle finger together, then pulled them apart into a V shape, some of the fluid remained stretched between the two fingers like a slimy bridge. "Seems to contain a mixture of two fluids. A slick low viscosity fluid mixed with a thicker, stickier, higher viscosity fluid that's more like a mucus. Fascinating," she observed. Rainbow watched on in mild amusement and then a bit of shock as Twilight carefully poked out her tongue and licked her middle finger. "Hmm," Twilight said. She took a longer harder lick, being sure to get some of the strands between her fingers. "Interesting flavor, strong but difficult to describe. Not unpleasant though," Twilight noted to herself. She looked up, Rainbow had her eyes open wide, jaw hanging low and her wings spread to full attention. "What?" Twilight asked.

"That... Was... Hot!" Rainbow said.

"Heh heh," Twilight said blushing furiously. She got up and went over to the sink to wash her hand off properly. When she was done drying her hands on the dish towel she turned back to Rainbow. "I-I was just studying your vaginal fluids. F-for science!" Twilight explained.

Rainbow chuckled. "Pretty sure science has already studied that kind of stuff Twi," she said with a smirk.

Twilight blushed again and looked down. "O-okay, it was for personal study," she said looking almost ashamed.

Rainbow quickly got up and went over to her, hugging her. "Hey, you've nothing to be ashamed of, like I said I thought it was hot," Rainbow assured her.

Twilight snuggled into the hug. "I-I know, I-I'm just embarrassed I guess," she said uncertainly.

Rainbow cocked her head to the side. "Why? I think it's great that you're curious about such things. I think it's sexy when you get science-y."

Twilight giggled and snuggled against Rainbow some more. With her face pressed against her collarbone Rainbow could feel that Twilight was smiling. "I love you, Dashie," she said quietly.

Rainbow stroked Twilight's mane. "I love you too, Twi," she replied. "Hey, you know what? We should get away from all this sex stuff and just do what we always do on a Saturday, read! Except this time we can cuddle together naked under a blanket. What do you think?" Rainbow asked.

Twilight looked up at Rainbow and smiled. "That sounds wonderful, Dashie," she replied. She then leaned forward and kissed Rainbow. They went to the main room of the Library where there was a couch, and true to Rainbow's idea, curled up together under a blanket to read the next few chapters of the latest Daring Do.

Author's Note

This took a bit longer than I had hoped, sorry about that. Anyway, not sure if the next chapter should be Twilight and Rainbow having sex for the first time or Twilight revealling the truth to her other friends (with Rainbow's encouragement). I want to do both, just not sure which I should do next. Also, if you have any suggestions on what else might happen in this story I'd like to hear them. Apart from the two ideas above, the only other thing I have is Twilight getting more... intimate with her other friends. Not sure if that is a good idea though.
