As I reach the library the air was just starting to chill. It is hard to believe that just three months ago I was debating if it would even work out between Twilight, Tavi and I; that just a few weeks ago, I found out I wouldn't be here forever, that my foals would grow up without me. Twilight and the princesses started their research to try and keep me here, but for now, I am to enjoy the time I have left.

Even the ponies that didn't like humans in general like Applejack have lightened up about me. I just hope that the princesses and Twilight succeed. If they don't, I don't know what I would do. My life, and family are here, and it hurts to think about losing them. For now though, it is time for Twilight and I to take care of something big.

Twilight went into heat yesterday. She needed a reason to get Spike out of the house, and setting him up on a blind date with Sweetie Belle was a stroke of genius. Though he also knows not to come back to the library should something happen. Twilight was just that prepared.

Knocking on the door, I prepare myself for an interesting night. It won't be our first, it will be our third. Tavi even got in on the act the second time, but this one is special. Tonight is Twilight's second day in heat, and my first time dealing with Twilight's fetish.

Twilight is a submissive partner, and has been interested in bondage since long before I met her. She asked me if tonight could be the night for this, and we spent last week talking about how it would go down and talking safety and all that good stuff. Thankfully, I talked her out of the old safe word. Sure, it was easy to realize it was a safety word, but saying 'hippopotomonstrosesquipedaliophobia' would take forever.

"-am. Sam? Are you okay?"

Brought back to the real world by Twilight, I realize I have been staring straight ahead for a time. The sight of Twilight in a robe almost pushes me back.

"Sorry Twi," I say, scratching my head all the while, "I kind of got myself...distracted for a moment."

"Oh it's no problem. Happens to me all the time when I'm reading a good book. Come on in though, I really want to get this started soon. This heat is a bad one since I actually have somepony this year."

To say she wasn't practically dragging me through the room with her magic would be a lie. By the time she's done talking, we're on the way to set up the main event. I admit I have never been into bondage before, but Twilight had plenty of well used books on the matter to get me caught up. Not to mention my previous experience as a sub during Tavi's heat.

As we enter her room I see that she has been busy setting up for tonight. There are straps and hooks from the ceiling, and some from the floor. Vibrators, dildos, mouth rings, restraints, and various outfits are set out in the room, as I turn around I see that Twilight has already picked out an outfit. More specifically, she was wearing it underneath her robe. It's a leather harness that hugs her curves very well.

It was probably custom made, as the back has room for her wings to be out, though they have some binds as well. Her breasts are forced to look perky from the straps that circle them, and a removable strap is all that hides her marehood from my eyes. Her tail, however, is conspicuously free, until I remember that subs like it free since it is easy to push out of the way. She then hands me proof that she trusts me: a black horn casing.

Most unicorns only need a small ring like the one I used on Vinyl a long time ago, but Twilight is too powerful for that. She's capable of shattering the rings with her power, and she wanted to trust that she wouldn't need her magic. Such a step for a unicorn, handing over an object capable of making them powerless, is a big sign of trust, one I dare not break.

"Twi, I will put this on you after we are completely comfortable with the set up. So I must ask-"

She silences me with a kiss. A simple, slow kiss, but one that tells me she wants to try this. As we separate, I can smell her in the air. It is becoming far harder for her to contain herself. She would if I wanted to stop, but I know that it would be hard on her. An image of Tavi from so long ago flashes in my mind. A gentle smile comes over me as I take Twilight's hand, and lead her to the suspension cables.

"I want this to be special Sam...we don't know how much time we have left, and I don't want you to leave without us having some special time together. The princesses and I are searching for a way to let you stay, but even if we do find something, we won't know if it will work until the day the portals close forever comes. I...I don't want to think about it anymore Sam. For now, I just want to enjoy being with you. I want this to last forever. So please, let's get started sooner rather than later."

I hold her against me tightly for a while, before taking her over to the suspension straps. A few clicks, and she's attached. I walk back over to her front, the straps still slack until I pull them taut and raise her into the air.

"Let me get ready real quick, then we can begin, if there is any discomfort, well, you know the signal." I hurriedly turn around, heading to the various outfits she has laid out I pick one that has a few straps and buckles. If I remember right, this is a basic male domination suit. There are straps to attach a female sub's head to the groin, and various containers and holsters for various toys. I quickly done the outfit after stripping, knowing that this will help Twilight get into the mood even more so then before. The leather feels weird on my skin, but the look on Twilight's face is worth it. A large grin she is barely able to contain floods her face as her blood follows.

"Remember, the safety word is 'Palindrome'. Please say it to show me you remember."

"Palindrome."

"Good." I grab a ball gag from a nearby table and walk on over.

"Remember, we begin after I secure you in the air. While gagged, your safety action is to...wait, we never talked about this. Well, can you whip your tail?"

She concentrates for a moment and before long, I hear the whipping of her tail.

"Good, that is the signal to use when you are unable to speak. Now to get you in the air."

I walk over to the place Twilight installed the anchor for her suspension system. Taking the rope ends, I pull them and lift Twilight up into the air. Since becoming an Alicorn, her overall weight dropped significantly to aid in the ability to fly. Her weight before was ninety-ish pounds, but now it is barely in the forties. I soon have her suspended and secured in the air, the hooks on the ends making it rather easy to do.

As I turn around, I adopt the character we have planned. What I do from this point on is my discretion, but at least Twilight gave me a book on this. I make my way over to her, and place the cap on her horn. She is at my complete mercy.

"Now, before I get down to having some fun, let me lay down some ground rules."

I can visibly see her tremble for a moment in excitement before settling down. She really wants this.

"You will not move or speak without my permission, otherwise you will be punished, is that clear?" A nod is all I need to continue with my act. "Well then, seeing as you can't really move, I wonder what will happen when I do this?"

A small, excited whimper is all I hear as I approach Twilight. As I put out my hand, I decide to see if Twilight's wing is as sensitive as Luna's. As my fingers gingerly begins to trace the edges of her wings, I can hear her breathing become more labored as she began to moisten.

I spend a long time teasing her wings, feeling her soft feathers against my fingers, and enjoying her whimpers and moans as her body begs for more stimulation. After a while, I finally decide to answer her call. I move and bend down in front off her, leaving my erection in her face, though covered by my leather gear.

I use my new position to taste her wings, using my tongue to stimulate her. All the while, my hands drop down and massage her breasts. She's moaning, but I can tell that if that ball gag wasn't in her mouth, she would be doing everything she could to get at my erection.

Not that it stops her from trying. I can feel her sniffing and rubbing at me, either trying to inhale more of the scent, or remove the obstacles preventing her from devouring me. It isn't hard to imagine her succeeding either. The fluids may not have an escape from her outfit, but her scent certainly can. The smell alone tells me that if she got free, I would be sore for a while. I continue my ministrations, slow and precise, just like her book said.

After some time I pull away. Twilight's face is covered with a large blush, the gag caked in her drool. She wants me, badly. I look at a clock, and notice it has been about thirty minutes since we started. I seem to be taking my time. A flash in the clock's glass face holds my attention for a bit longer, but that was quickly pushed to the back of my mind as I remember the next step.

"Now my dear Twilight, I think it's time we remove that lovely ball gag for a time. It seems to me that I have a problem that requires nice holes to use, and I think your mouth might just be that fit. So what do you say we experiment and see if it holds true, hmm?"

Twilight nods her head as much as the contraption allows, and a smile crosses my face as I undo the clasps holding up the flap concealing me from her view. When it drops, her eyes widen in eagerness, my dirty talk getting her well into the mood of the submissive partner. As soon as I remove her gag, her mouth attempts to engulf my member, her progress hampered by the straps suspending her in the air. She still manages to take my head into her mouth, her tongue immediately getting to work on me. I pull away to protest, but then she makes a mistake and speaks.

"Please give me your cock to suck master." A stern look is all it takes to remind her of her temporary place, not that I was stopping there.

"Well, there you go: you broke the rule, you talked without permission. I'm still going to put my cock in your mouth, but just for that, I will be taking your throat too, you little whore."

I can tell how excited she is getting: her smile, her twitches, her shaking as she stares down my cock. It almost makes me think she does it on purpose. As I walk forward she fights the temptation to simply rock towards me, knowing I would simply tease her some more or make her punishment worse. As I get back fully into range, I give her the series of commands that she was waiting for.

"Open your mouth." She did so without any hesitation. As I slid myself in, I let the head of my dick rest on her tongue.

"Close your lips, leaving your teeth out off reach. As a side note, if you feel the chocking is a bit much, just placing your teeth on me will force me out, no need to get drastic. This is, of course, if you can't whip your tail. That is all."

Before she can complain that I should have thought about this before, I grab the back of her head, and force my shaft fully into her, easily making it into her throat. It...is...heavenly. Her throat tries to fight my intrusion while she's resisting the urge to fight me. She actually tries to get even more of me into her mouth. It was then I realize something is different than I expected: Twilight isn't gagging or choking, she's completely used to having something in her throat. I want to ask, but that would have to wait. For now, I'm going to get a bit more stimulation.

I pull back, almost leaving her warm, welcoming mouth, before plunging all the way into her throat again. She gives me a throaty moan as I begin to gently pump into her throat. She simply lets me do what I want as she fully relaxes her throat, and all I hear is *gluck, gluck, gluck*. It seems she meant it when she said she really got off on bondage. I'm going to have to ask her how often she practiced to reach a higher climax.

Soon, I am easily sliding in her throat, when I hear a tail whip. I stop, pulling out completely, as Twilight coughs hard, her body deciding oxygen is more important. After a while, she speaks.

"Alright, I think I'm good, though I don't think my throat can keep going. A real phallus is just too much for me right now." I am certain she would blush harder if she could, but for now, it seems she is good enough to continue. I will give her a little more time.

"Well then, before I ravage you some more, why don't you tell me about these,' experimentations'." Again, her blush that wanted to disappear instead returns full force.

"Well, when I would...masturbate, I would make a...fake magical dildo, to practice on. It just made it better." Her eyes avoid me, but after that, I am going to make this her night.

"Is that so?"

I grab her chin with one hand and force her to face me. As she tries to say something, I kneel down and lock my lips with hers, reassuring her I am not judging her, and reaffirming my love. She returns the kiss, our tongues twirling in each others mouths, until I finally break contact, ending the kiss with a kind smile. Then I return to my performance.

"Well, my little pet, how about we get going and I find out just how loud I can make you scream through a gag."

A smile returns to her as she realizes the fun has not yet stopped. I put the ball gag back on after making sure it's clean enough, having discarded it rather haphazardly when I took it off. Noticing it could use a small cleaning I excuse myself and wash it off in the bathroom before returning it to its duty, trying to silence Twilight.

As it gets fitted into place, I slowly glide my hand down her wing from tip to base, before slowly gliding towards my target. As I get closer to her favored place, I have to remember what she wants me to do next. There are a lot of possibilities after all. In an instant, the answer hits me.

I will start her off lightly; a little touch, a little licking, before I take a vibrator to her and prepare her for penetration. Not that she needs the attention, I just want her to get as much out of our time together as we can. As I pop one of the buttons that holds up the flap, I can see her body tense, she's definitely ready. Then the smell, oh that smell. She reeks of desire, of want, of sex. It's absolutely beautiful. I then undo the other button, and get to see the results of my efforts. She's not just soaked, there's an actual puddle forming from her juices.

"My goodness, somepony just could not contain themselves I see. Why, I dare say there is a leak here." I can tell she is eager to see just how I will treat her, and thanks to her book, I know a few methods to take care of this.

" Let me see if I can plug it up with this!"

I quickly plunge my pointer finger into her and hear her moan loudly as a response. Her walls clench hard, both in pain and pleasure. I listen for the distinct sound of a whip, but fail to hear it. Instead, all I hear is her pleading grunts as she tries to feel even more pleasure.

"Now now, no need to beg that much for me to continue."

I begin to pump my fingers into her slit, constantly changing my speed and depth. It drives her crazy, one moment I am doing too much, the next, not enough. She thrashes around and soon I am definitely seeing the appeal of this. Her pleasure is mine to command, and only I can give her what she wants. At that moment a flash catches my eye. Turning to face it I see Twilight's mirror, but what it reflects is not Twilight and I, but Mariana.

In an instant I am completely overcome with fear. The instinct to run nearly overpowers me, yet my fear stops me. Somehow, I manage to pull the quick escape, sending Twilight roughly to the ground before I lose the ability to stand. My breathing increases, my body grows cold, and time seems to come to a stop as I merely gaze at Mariana in the mirror, smiling widely at the scene before her.

"What the hell Sam, why did you- Sam, are you okay?"

I feel Twilight embrace me, shielding me with her wings, and finally blocking the mirror from my sight. In an instant, I feel the tears fall down my face as relief flows through me. It takes a few minutes, but when I finally calm down Twilight has a question for me.

"What happened?"

"I was...I was getting into it, really starting to enjoy the feeling of power when I saw a flash in your mirror. I looked and saw Mariana standing in it in place of us. Twi, I felt like I was becoming Mariana. I'm sorry, but, I-I don't think I can do this."

The tears flow as Twilight holds me close, burying my face in the crook of her neck. It takes another few minutes for me to calm down, and then Twilight speaks again.

"It's okay, I don't want to push you. It may have been fun, but I don't want you to be this way. I enjoyed our other sessions, so maybe tomorrow we can just try it without any such kinks. Tonight, let's get some sleep. We can try and do something in the morning."

I cling tightly to Twilight as we go back to her bed. She gets into some underwear and we fall asleep, cuddling in the bed.

****The second night after****

Once again, only Twilight and I remain in the library. Spike is staying over at the Apple's before going on a camping trip with the Crusaders, Applejack, and Big Mac. This leaves Twilight and I alone for round two. All day she was giving me hints that she was going to rock my world, and she certainly proves it the moment the library closes. She sound-proofs the room before quickly jumping on me, locking our lips together on top of the central desk.

Her tongue quickly invades my mouth, tasting every corner before I even have time to recognize what's happening. The sensations hit me at once as she rapidly teleports us to her room. The feeling of being everywhere is far less intense than before, and thankfully I'm not nauseous when we land, but the trip made certain I'm not able to match her enthusiasm.

She uses her magic to tear her clothes off of herself as she retreats. Thankfully she was kinder to me, leaving it at 'quickly removing' my clothes. I'm not even close to fully erect, but her somewhat skillful hand and the smells now permeating the room quickly remedy that issue. As our tongues continue to dance, I begin to lose myself in the moment, groping at her flanks and rubbing her cutie mark. I even went as far as to lick at her horn, a very intimate gesture, before Twilight pushes me down, her eyes shining like a cat's.

"No time for foreplay. I have been a very good filly, and I want my reward."

In an instant I feel her warm, velvety walls encircle my member. In the next, her warm tongue invades my mouth again. In the third instant, I felt her soft, full breasts meet the palms of my hand. I squeeze, and finally, time flows normally as she rides me for all I am worth. Not once in her motion does she pop me out, not once does the pleasant feeling stop. She even uses her magic to massage my shaft and balls, and rub her clit.

I begin to vigorously massage her breasts as my senses catch up, followed by my tongue beginning to duel hers. Finally, my hips start to rise, wanting to remain in her warm depths as much as possible. This is not just making love, I realize, this is far more primal. We are fucking, fucking like wild animals. All that matters is reaching climax, and placing my seed as deep inside her as possible. Soon, I feel the sensations rise as her walls begin to pummel me with sensations. More and more I get closer and then...release.

Twilight cries out as her body responds in absolute joy to the seed flowing into her. Her body, already on the verge of climax, basically received the sensations twice. Her walls clench so hard, it actually hurts on occasion. Eventually the sensations start to subside, and I hear Twilight finally release a primal cry of pleasure. I wonder if I also did such a noise at my peak. The memory of the previous motions slowly sink in, some lost forever, as we come down off of our first release. Twilight falls on top of me as I continue to massage her breasts, her tunnel keeping me more than ready.

A few minutes pass, and Twilight begins to moan again as she uses her arms to raise herself above me. She smiles deeply, my hands still massaging her breasts as she begins to slowly move on my shaft again. I rise myself to suckle on her right breast and begin to take in the textures. Her breast is indeed soft, her fur coat here thin and silky. Her tunnel, still warm and very wet, grips me tightly, loosening only while I push in, and growing tighter as I pull out. I hear her begin to pant as she begins to try and bounce on me a little faster.

I answer by moving my hips a little harder and deeper. Thanks to our slower start, this time the sensations are clear, and certainly more fun. I feel her walls contract, Twilight seems to be getting close, but I still haven't reached a warning sign. I at first think of slowing down, but soon realize that Twilight is not getting any closer to her release. It seems her body still succumbs to the same problem: early climax.

Even in our previous sessions her body quickly reaches climax, more or less ready for a stallion, notorious for their quick shots during a mare's heat, to fill her. As much as it pains me, the only way to get her to reach a full climax again during her heat, is to come inside of her again, bringing her through even more partial climaxes. To me this also represents the reason Twilight was scared of sex at first: most mares can't have simultaneous orgasms. She can.

The pain of being stuck on two orgasms, as well as feeling those orgasms release, can be excruciating, but she has said how painful it can be to be in heat and unable to fully climax without a real partner. Soon I feel another sensation on my shaft and balls. Twilight has cast a spell and is now beginning to lose it. I finally leave her breast, and take her horn into my mouth. Her motions stop, so mine increase to compensate. She begins to moan loudly, and I finally get my warning sign. A strong feeling soon overpowers any thoughts, I'm quickly reaching my climax as the sensations in my shaft increase.

I can feel every fold in her walls, every inch of her tunnel. I can feel the slight differences in texture from her more sensitive spots and the less. I can feel her contractions coming closer. Suddenly, I can feel what she feels, and I have the feeling she can feel what I feel as well. I can feel my inside of her from both our points of view, the feeling of having a shaft deep inside myself, rubbing against folds I do not have. I can feel her breasts, the sensation of my hands that found their way there, rubbing them and generating so much pleasure.

Finally, I can feel her love. I know how much she wants this, how much she wants me and Tavi. I can understand exactly what she wants from me. The thoughts and feelings flash through me, and I release my biggest load deep inside of her. I keep cumming for what feels like minutes. When I finally stop releasing myself, my shaft softens and exits her body. Twilight shortly afterwards collapses onto me, and I feel my fluids and hers drip from her body. I guess she used some spell to release my full seed into her at once. I can feel her literally shake with pleasure, joy, and fulfillment as she begins to claw onto me. We share a deep, intimate kiss as we slowly fall asleep.

"Hey Twily! We came to...visit...you."

Twilight and I lock our eyes on the intruders who had just burst in, ruining the romantic moment of falling asleep in our embrace.

"Shiny, this is why I tell us to not just barge in. Things like this can happen and it won't be a four way anytime soon with her in heat."

"Sorry Twily, we will give you two a moment to get dressed and join us down stairs, we have big news to share!" With that, Cadance and Shining leave the room, leaving Twilight and I confused as to what this could mean. Excited at the possibilities, we quickly get dressed before heading down to find Cadance and Shining sitting at the table in the middle of the library.

"So then guys, what's the big news?"

"Yeah BBBFF, what's the big news?"

"Well Cadey and I just thought you would like to know we found a way to keep your coltfriend here in Equestria, kind of."

"Cadance, could you please repeat that again so I can make certain I am not hearing things?"

"Yes Sam, we think we know of a way to keep you here in Equestria after the worlds merge. Such wonderful news, I know. It will require Octavia, Vinyl, Twily and all your other friends here, but it is possible. We will bind you here with the love and memories you possess with your friends and new found family."

Joy, overwhelming joy. It will take a while to prepare everything, but we have time. We know when the portals will close, and understand the ramifications better. Oddly enough it would happen on December 21st, 2012. A day thought to be the 'end of the world'. If the spell happens to fail, I'll go to Earth again, but due to the way things have to be, information will be lost. Memories will be altered to the point where the memory of the two universes colliding will disappear.

I will have to forget about my friends and new family here. It honestly scares me. Some memories might be retained, but the only sure fire way for me to remember Equestria, is to remain here.

The only problem is that, should it fail, my memories will be ripped from me instead of being rewritten. My mind damaged, though the implications of being with Mariana again might make that far fairer fate.

We talk long into the night before settling in for sleep. Plans were made, thoughts buzz around my head, and everything seems to be going my way. Fate, on the other hand, has a different plan for me.

Tavi and I are taking a nice stroll through the park. Such a wonderful time. We have been so excited in our preparations now that I should be able to stay here in Equestria. Our belief in the princesses gives us the knowledge that they will succeed, and as such we have celebrated to some extent. Everything is perfect.

"Lucky me, my prey isolates itself."

Before I can react from my blissful dream, darkness overcomes me. The familiar voice haunts me as consciousness itself fades from me. If what I hear is real, I can only hope Tavi will be safe.

If only I knew what was to come.

Author's Notes:

For those wondering, The Threesome may be a special chapter in the future, I make no promises though.
hippopotomonstrosesquipedaliophobia is the 'fear of big words'. Ironic, isn't it?
(note: Irony is something that goes against what is expected)

I originally planned a longer domination scene, making Sam get the the verge of orgasm before a VERY quick reduction, but felt this was more like the character.

After a first orgasm if you plan to continue so your lady gets a second one, massaging her breasts or another erogenous zone can help her become ready, without the soreness of her now VERY sensitive vagina. The more you know!

There are two possibilities for the evil doer, who do you think it will be?

Finally, I am myself a dom., I haven't any, experience, in the sexual arts (I.E. virgin) but I can say this, nothing makes me softer then claustrophobia.

The best laid plans of mice and men... Also, if you want a Cadence scene, that can be arranged... not sure how yet, but it can happen...
