It was a rare night alone for Rick and Twilight. Twyla was off for her first year at the magic academy and Sterling was currently sleeping over at a friend's house for the evening which meant the two adults were alone.
Rick had made a sumptuous dinner for the two of them, they were working on their second bottle of wine and were currently in the midst of a make out session on the couch in the living room.
Twilight sighed as her husband nuzzled at her naked breasts. She stroked his head and occasionally gasped when his tongue tickled one of her nipples. "You sure do love my girls, don't you?" she teased.
"You kidding? They're the primal root of a woman's charms they are. Besides, you don't have these as a pony, " Rick said coming up for air before kissing her fiercely.
She returned the kiss with equal passion. Her desire for this man was just as strong, if not stronger, than it was when they had first admitted their love for each other. There were times she couldn't wait for the end of the day just to be able to see him again and to feel his strong arms surround her. She loved how much attention he paid to her and not simply because she was his wife. No, he saw her as a woman regardless of which form she wore.
"So which you do you prefer? Human Twilight or Pony Twilight?" she asked when they finally separated.
"That all depends on which one is in front of me at the moment, " he replied with a wink. "The only thing that I do miss sometimes is me as a human and you as a pony."
"Really?"
"Yeah. I mean that's how you looked when I first met you and that was a good year of our time together," Rick said running his fingers through her hair. "There are times I miss those days when we were both younger, falling in love for the first time with each other and just spending every spare moment together."
Twilight smiled before saying, "would you like to give it a try?"
"How? Babe, we're human here and ponies there. Unless you've got a way that I don't change on traversing the portal, I think we'll just have to stay the way we are. Not that I mind as you're still my Twilight no matter which form you're in." Rick leaned over and kissed his wife one more time while she melted into his arms.
"Actually there might be a temporary way to fix that."
"What, seriously? So we'd go to Equestria and I'd stay human while you turned into a pony?" Rick smiled and in his aroused state was pretty eager to give it a shot. "Provided there's no danger or this change isn't permanent or anything."
"No, just a temporary spell like the one I used to cast on myself when I wanted to go human for a bit. C'mon!" she took hold of his hand and led him to the portal. They opened the door and the library was closed. This of course meant that Spike had gone home for the night so they were guaranteed not to be interrupted.
She cast her spell on Rick who felt a slight tingle run over his body. "We now have 1 hour so let's make the most of it!" Twilight said as they both walked over the portal and into Equestria.
"Twi? I think something happened, " Rick in his pony form said while looking up at his wife who was still human. They walked back to Earth and remained exactly the same. "Okay, this is definitely weird."
Twilight went over the spell in her mind but couldn't see what could have gone wrong. Her mistake of course was trying to cast a spell when drunk and she had reversed the integral. Their only hope was to wait it out until the spell ran its course which left them with an hour to kill.
"I guess this kinda kills the mood, " Rick said with just a hint of disappointment in his voice.
"Why do you say that? You're still a sexy beast whether you're in your human body or this one, " Twilight said running her fingers through Rick's mane. He snorted a moment and almost stamped on the floor. "Did somepony like that?" Twilight teased as she ran her fingers through his mane again.
"Babe, that is awesome, I never realised how good that felt to be on the receiving end of this." A moment later she was squatting down in front of him, completely naked as she was before but she drew herself to his muzzle and kissed him. It didn't take much coaxing for Rick to kiss her back. The problem was in this form he was a lot stronger than she was and had to maintain a modicum of control.
This felt so different kissing her when he was a pony and she was human. It must feel really strange for her as well. They broke the kiss and stared into each other's eyes. A naked hunger for each other burned deeply within them both and they were more than ready to continue. Without saying a word, Twilight led him up to the living quarters of the library and to her old bedroom. The bed was still there, although rarely used nowadays it brought up such nostalgic feelings that neither one could let it go.
Twilight sat down on the bed and Rick sat down next to her. They started kissing again, Twilight running her fingers through his mane sending little electric shocks down his spine as she did. While one hand worked its way through his mane the other one traced its way down his belly until it rested on his sheath and the penis that lay protected within. Rick nickered slightly as she gently massaged his balls and ran her fingers over his rapidly growing member.
It wasn't long before he was fully erect and stood at an impressive twelve inches. Rather small for an earth horse, but about average for a pony. Twilight grasped it with both hands and slowly jacked him a couple times. "I'm guessing you like this?" she teased.
"Keep that up and you'll see how much I like it. But I can think of better things to do with it however, " Rick said as he pushed her hands away. The last thing he wanted was to come outside of her.
"What do you suggest?" Twilight asked playfully.
"There are certain things we've never done simply because our forms were wrong. We've been presented with an opportunity to do something we might never be able to do again. Think of it as... fucking for science. Something that is purely in the realm of discovery with no reason other than that."
"Yeah, there's the sexy talk that I like. Now talk physics to me baby!" Twilight joked.
Rick gently pushed Twilight down on the bed then positioned his face directly over her vulva. He was intimately familiar with his wife's genitals, but he lacked the fingers he usually used when Twilight was human. On the other hand, his tongue was longer and stronger in this form so maybe it could make up the difference.
While he was looking at her pussy and deciding what to do, Twilight took the incentive to take his stallionhood in her mouth for the first time. Or at least she tried to take him in her mouth. She had faced the same problem in her younger pony days when experimenting with a cute stallion she knew. Even back then, pony dicks were just too big for her to take orally and now that she was human with a smaller mouth it was simply impossible short of dislocating her jaw. She was however able to suck on the tip while she stroked him with both hands.
Rick let out an explosive breath when he felt her lips close around his penis. The warm wetness of her mouth bathing the head of his dick felt incredible. Her soft tongue gently caressed him while her hands stroked the shaft and tickled his balls. He only paused for a moment before leaning down and sticking his muzzle into her sex.
Her scent drove him wild with desire as he brought his nose in close. He had to taste her, to spread her lips with his tongue and lap up her juices like never before. It was messy since he didn't have the fingers necessary to spread her lips apart before attacking her pink insides. But his muzzle more than made up for his lack of digits. With a little work he was able to drive his muzzle right between her folds which left her wide open and ready for his tongue.
Licking gently around her lips he heard her muffled gasps around his cockhead as he licked and probed at her. Sticking his tongue in a little deeper, he probed her depths a lot further than he could have as a human. Twilight shuddered underneath him as his tongue reached places she never would have imagined before. He swept his tongue around until Twilight yelped when he touched one spot.
"You okay?" he asked with concern as he pulled away. "I didn't hurt you did I?"
Twilight shook her head and said, "you touched something in there that just sent an shock through my system. It was as if you had touched my clit but on the inside."
"Do you want me to try again?"
"If you don't mind."
So once again Rick placed his muzzle against her dripping pussy and worked his tongue in and around until he found the right spot. Twilight once again yelped but this position was very awkward for him to reach it so he rather reluctantly moved around so he was now facing her. It meant he wasn't getting any more head, but if it meant that Twilight could enjoy this session more he was willing to put up with a little discomfort for the time being.
Again, he brought his muzzle to her sex and licked her juices before driving his tongue into her and massaging her inner walls. It was a lot easier to reach it now and his sensitive tongue proved adept at manipulating whatever it was. He attacked it with abandon while Twilight thrashed about and lost herself in the sensations.
What happened next surprised both of them. Twilight felt her orgasm approaching rapidly but also felt a strange sensation and a need to bear down on it. Her moans and cries of pleasure turned to shrieks as her climax approached, Rick continued to work his tongue and finally she came in a way she never had before. Usually, there was a rush of juice, this time there was a flood of it that blasted into Rick's mouth, he pulled away in surprise as Twilight continued to squirt over and over again before collapsing on the bed, totally spent.
She was breathing heavily but had a dreamy expression on her face, totally oblivious to the mess she had just made and the weird look on Rick's face.
"Uhmmm... babe?" Rick asked.
"Mmmmm?" she purred while gazing at him through half-lidded eyes.
"I think we just found your g-spot."
"Sorry? What was that?"
"I think we just found your g-spot. It's a part of the female reproductive system that when stimulated creates what's called 'female ejaculation' and causes a big mess to be made."
Twilight looked down and noticed the quilt had been soaked through as well as Rick's muzzle practically dripping with her ejaculate. "Wow. That was incredible. I've never felt something so strong in my life, it was like having sex for the first time."
"Glad I could be of help and as I believe you're ready, how do you want it?"
Twilight took a moment to understand what her husband was referring to when she caught sight of his member currently peeking from out of its sheath. "Oh, you poor dear. Waiting on me like that. Let me help you get that ready. Lie down here, " she patted the bed next to her and Rick lay down as requested.
Kissing him passionately on the lips before doing anything else, Twilight tasted her residue before kissing her way down and starting to lick her husband's dick. She grasped it with both hands and ran her tongue over the slowly growing shaft and placed gentle, wet, sucking kisses all over its length. Occasionally she'd tickle his balls or suck a bit on the tip to keep it from getting boring and once he was fully hard she squatted over the head and slowly lowered herself onto it.
There was a moment of resistance as the flat head touched her lips and Rick had to hold himself back from trying to thrust his hips forward but finally, with a gasp, the head penetrated Twilight and she sank down on it. The occasional gasp or grunt escaped her lips as she impaled herself on his massive cock until finally, with a gasp that was halfway between pleasure and pain her hips came to rest on his.
She leaned forward, his hooves went around her neck and they kissed deeply while savouring the feeling of being joined like this for the first time.
"Damn, you're tight, " Rick gasped.
"Damn, you're big, " Twilight replied.
"Finally! We've got to find a way to make this change permanent, " Rick said with a self satisfied smile.
"Don't get your hopes up pony boy. And you're still a good size when you're human, this monster is almost too big for me."
"I'm not hurting you am I?"
"No. Just give me a few moments to get used to this thing before we do anything else."
"Take your time. The way this feels, I don't think I'm going to last long."
"Good because I don't think I could last long like this either. Okay, I'm going to start. Please, if you do start to move, be gentle." With those words Twilight started to slowly rock her hips back and forth, slowly fucking herself on her husband's horse cock.
"Mmmmmm, " she moaned as her face screwed up in what Rick hoped was pleasure. He wanted her to enjoy this as much as he was but that didn't mean a thing if she was hurting herself in the process. "Ohhh, that's good."
Placing her hands on his barrel of a chest, Twilight started to rise and fall on his dick. Her eyes were closed in concentration, it wasn't easy but she had to take this slowly. If she attempted to move too quickly she might get hurt. Rick was breathing hard and it was a struggle for him to ignore his instincts and just rut her like there was no tomorrow. So he lay there, his hooves lovingly caressing his wife as she worked her magic on him.
Twilight's breath was coming in short gasps, her head thrown back and one hand busy playing with her breasts as her other hand supported herself. Her movements started to get erratic, she leaned back and with her free hand tickled her clit which sent her over the top and she orgasmed loudly.
The look on her face as she came and her vaginal walls putting the squeeze on him like never before, Rick had no choice but to cum as well and yelled while he blasted copious amounts of his seed into his wife. There was so much that it spurted out of her pussy and landed on the already soggy sheets over and over again.
Twilight collapsed forward onto Rick's chest and just groaned happily while Rick's hooves continued to caress her.
After a few moments of this, he had shrunk and fallen out of his wife and most of the sperm he had pumped into her flowed rather messily out of her.
"That was incredible, " Rick said as he nuzzled Twilight.
She smiled dreamily at him and lightly kissed him on his muzzle.
"Does anypony use this room anymore?" Rick asked.
"Not really why?"
"Well, it's just that we might have ruined the quilt, the sheets and the mattress and if somepony else is going to be using it we'll need to clean it up before they do so."
"Mmmm, you're right. But we're not doing it now, " Twilight said before pulling herself to her feet with a tired groan. "Right now, we're getting cleaned up. Then I'm going to sleep. But just in case, " Twilight glanced at the window and opened it letting the fresh air in and hopefully it would help to air the room out a bit.
"That'll work." Rick said as he hauled himself to his hooves. "Sorry about all that."
"What are you talking about? The sex was wonderful, " Twilight said.
"I was just commenting on how you were walking. You look a little sore, and you're still dripping."
"It's okay. I'll be fine tomorrow. And it was worth it, " she said as she reached down and ruffled her husband's mane. They made their way downstairs and back through the portal where they remained the same as they were before. A quick shower and they went straight to bed, falling asleep almost as soon as they lay down.
The next morning Rick had returned to normal. Twilight had already gotten up and had left for the day. Rick got up, had a quick cup of coffee before clearing the dirty dishes from last night and cleaning up the kitchen. He decided to check up on Twilight to see how she was holding up and made his way to Equestria.
He found her at her desk, she took one look at him when he came in then blushed furiously while writing something down in her book. Trotting over to her he kissed her and asked, "something wrong babe?"
"Spike is upstairs dismantling the bed. He wants to turn the room into a storage room because the one in the basement is full."
"The bedroom?"
Twilight nodded.
"The same bedroom we made a mess of last night?"
Twilight hung her head in shame and nodded weakly.
"You want me to talk to him?"
If it was possible for Twilight to act any more like Fluttershy she would have done so by now and she gave the barest hint of a nod. Rick gave her a quick hug before going upstairs to see Spike.
"Hey Bro, I popped by and Twi said you might need some help?"
"Oh hi Rick, yeah I figured it was about time to move this old thing. Nopony uses it anymore so it's just taking up space. Besides I think some foals broke in last night to use it."
"Really? What makes you say that?" Rick said evasively.
"The window up there was open this morning and they made a mess of the quilt, the floor, the sheets and the mattress. It's probably for the best that I just bring these outside and burn them all.
"Damn kids, " Rick muttered with as much conviction as he could muster.
"You can say that again. What would their parents think?"
"I don't know, but let me give you a hand with carrying that stuff, " Rick said as he got part of the mattress balanced on his back. Spike held onto the other end and they marched it downstairs to behind the library where Spike incinerated it until nothing was left but some fine ashes.
"It's a shame really, " Rick said as they cleaned up the ashes. "If that mattress could speak, it would have quite a story to tell. Lots of memories of good times." He smiled remembering the times sleeping with Twilight on that mattress as well as the fact that the evidence of last night's escapade had been dealt with once and for all.
"You can say that again. You two sure left some memories on it last night, " Spike said casually.
Rick whipped his head around to look at his younger brother. Spike was currently trying desperately not to bust out laughing having known all along what had happened. "How did you know?"
"Bro, I'm a dragon. This nose, " he said bringing a claw to his snout, "can smell a gem at 100 paces. I can track ponies that have passed through a busy square days before. Catching your scent up there was foal's play. I'd recognise it anywhere. Twilight's however was different. It was almost the same but not quite so I figured she cast a spell to turn herself human and you two went at it."
Rick started to laugh having been caught out and it wasn't long before Spike joined in. "You didn't mention this to Twi did you?"
"No, I didn't want to embarrass her."
"Good choice. Well, I hope you'll keep our secret?"
"I think I can do that for a price, " Spike said with a predatory grin.
"Seriously? You're going to blackmail me?"
"Blackmail is such an unsavoury word. I prefer the term extortion. The "x" makes it sound cool."
"You've been watching too much Futurama. Okay, what's it going to be?"
"Well, first how about a sapphire cupcake down at Sugarcube Corner? Then a free massage every month for Rarity and I get the pick of the best gems she gives you."
"So long as Twilight doesn't find out, I guess I have no choice. Let me get some bits first as I didn't bring any with me. Just come in the library with me, " Rick said. Spike followed him in, finally happy to get one up on his big brother. He really didn't want to do this, but it was all in fun. After the cupcake, he'd say that Rick suffered enough and that he'd drop the rest of the terms. After all, they were practically brothers and Rick didn't deserve to be dragged over the coals for something small like that.
"Hey Twi, got some bits on you?" Rick asked upon entering the library.
"Sure, why do you ask?"
"Well, I figured that since Spike did such a great job on helping get rid of that mattress I'd treat him to a sapphire cupcake down at Sugarcube corner."
"Okay, " she said while giving him some bits. "You two have fun."
"Oh we will, and by the way, Spike knows what happened upstairs last night."
Twilight let out a startled "eep", Spike's face dropped as he lost his only bargaining chip and Rick just smiled at his brother, said "gotcha!" and made his way to Sugarcube corner to get that sapphire cupcake. After all, a deal is a deal.
