The Only Chapter

A Bathroom Bond

“10 minutes into 3rd period, 3rd floor bathroom, in the stall.” You read the text message and felt yourself get a bit nervous. You had been talking with, then fooling around with her since the third or fourth week you’ve been here, mysteriously brought to this world where all of the kids have odd skin colors. They reminded you of this old cartoon you watched when you were little. But the kids seemed to accept you fine, even as a transfer student coming in midway through your senior year. You obviously didn’t look out of place in a high school, so there really wasn’t anything that made you stand out. Your modest 5’11”, athletic but not too muscular build, and your unassuming face with a dark brown mop of hair seemed par for the course at any school, even this one with magical students.

You meticulously check the clock in your class, watching the second hand spin, and the minute hand get closer to the moment you’ve been waiting for. Your pencil taps on your notebook, not even hearing what your teacher is talking about (and not caring for that matter). The 10 minute point hits, and your hand raises. You ask to go to the bathroom, and pack up your stuff, leaving your backpack at your desk.

You make your way up to the third floor, and wander by the bathroom. Since it’s the middle of the period, there’s not much traffic, just someone at the urinal, so you make your way into the small stall. You sit down on the toilet to not arise suspicion to the other person, and you wait. It was only 30 seconds more, and you hear the door hit the frame as it closes. “All Clear”, you text to Twilight as the door opens not 15 seconds later, the familiar sound of the boots come within earshot. She twists the deadbolt on the door, making sure no one can get in. You look under the stall and see the purple legwarmers, and you suddenly feel your heart go even quicker.

She knocks on the stall, and you turn the lock, with her entering. “Whew! I had trouble containing my excitement, I almost lost concentration and broke the spell. Good thing I made it here.” The sound of magic being used suddenly fades, and a bulge appears in the purple skirt, with something else purple appearing right under the hem. It’s a lighter shade than the skirt, and you immediately recognize the scent it gives off. She definitely was excited, very much so. “Now that I’m here, let’s get to what we’re both waiting for.” She slides her panties towards her ankles, and the lavender shaft falls out unceremoniously.

Your modest 6 inches pales in comparison to her 10 inch, 3 around, thick-as-your-wrist equine member, still soft. The orbs underneath it were a darker purple, about the size of a ripe avocado. The scent they gave off was aromatically dense, but a tad sweet. It was a scent you had grown to love, after experiencing it so many times. “Don’t just stare at it, get to it!” She grows impatient, and your mind breaks out of its trance. You grasp at the globes, one hand for each. They fit perfectly, alluding to the earlier comparison. You start to fondle the ball in your palm, which elicits a groan from your girlfriend, and a shudder following. You work on those for what seems to be a minute, rolling them in your palms and fingers, tenderizing the sensitive skin.

You move up to the shaft, as it bobs its way to a full 13 inches, 4 around. The tip is still of the same circumference, but not for long. You reach your lips out, and give the tip a peck, causing Twilight to shudder as you can see she’s getting a bit frazzled. You open up your mouth, and stick the tip inside, taking a moment to suck a bit on the head. You go down more on to it, your lips acting as a studfinder as they cross the veins snaking their way down the shaft, still bobbing with excitement. You make your way about 2/3rds to the base, only stopping as it reaches the entrance to your throat. You bring your head back, removing everything but the tip. You spend the next few minutes repeating the process, up and down you go on the cock, precum sliding its way down your throat as it hits your tastebuds. Not too salty, a little sweet, a perfect aphrodisiac. With one hand on the base, and the other on a ball, you make it even more pleasurable, stroking and fondling as you suck. You feel her testicle tighten slightly in your hand, and you feel everything suddenly coming to a halt. She has pulled out, a string of pre glistening off of the tip, just hanging there.

“Now comes the real fun. Get those pants off, turn around, and get ready. I’ve got something that can help.” She rummages in her skirt pocket, and pulls out a small vial, with a blue liquid swirling inside.

“Endurance,” she says, “it’s supposed to make it last a lot longer, and make it even better, with a huge finish. I picked it up from Zecora back home. I keep a stash of it on me for special occasions.” She uncorks it, and downs the whole thing in one gulp. You begin to undress, your modest boxers and jeans hitting the floor, your shoes and socks making a pile in the corner. You keep your shirt on, as you’d just feel awkward being completely naked in school.

Covered in your spit and a small amount of pre, Twilight has deemed it acceptable for entry, but not after preparing your entrance. You hear a slight “slurp” as she licks them, and probes your entrance, loosening it up a bit and making sure it’s ready. You place one hand on the bar, one on the back wall, and raise your backside in the air.

Her hands grip your hips, and the flat tip prods against your prepped hole.

“On ‘Three’”, she says, counting down.

“2”

“1”, and just like that, she enters you. You grimace as the head slides in, stretching you out. You both groan at the same time. Her from pleasure, you from a mix of pain and pleasure. She slides it in even more, going slow as to not cause too much agony in your backside. She pushes about halfway in before she pulls back out, and you feel absolutely empty for a quick moment before she places it back in. This time she goes quicker, and starts to thrust.

“This is fantastic, the potion really seems to be working!” She says, “I feel like I’m going to cum but the urge just keeps growing!” You feel it along with her, her cock pistoning in and out of your tight ass, hitting your prostate in the process. The heavy purple balls slap against yours every time, making the both of you even more aroused. You feel yourself get closer every time.

The routine of in, out, in out, and the slapping of testicles goes on for minutes. You can barely hang on to the bar, and your hand is slipping off of the wall from the sweat created by the act. Her thrusts got even easier once her precum continued to flow into you, so much so that there’s a small bulge in your stomach from all of it.

“I’m about to…“ You reached your breaking point, and you grimace, groan, and almost cry out when you cum. Your dick spasms, and she slows down for just a second to let your seed fly right into the toilet, after 15 seconds of spurts, she continues picking up the pace, but her strokes get shorter. You start to lose some feeling in your arms and legs. Your legs start to feel weaker, like they almost aren’t there anymore. You gasp as your feet start to rise up, your lower leg merging with everything above the knee, as they take on a familiar purple hue.

“Wh-What’s happening to me?” you stammer out, as your backside seems to have merged with her crotch, that deep purple spreading from where her dick was.

“I don’t know, but it feels too good to stop!” She squeaks, as the potion takes its true effect on her, now also your body, which is reshaping with every second, every thrust. You look down to see your legs have merged with her balls, now growing them to the size of volleyballs, and the dark purple has stopped at a ridge, your hips up now the only unaffected part, but not for long. Your arms weaken now, and they start to dangle at your side as she pumps her hips back and forth. Every time a part of them hits your side, it feels like they are stuck there. You see your fingers, then your palms, all the way up to your shoulder, seemingly deflate and recede into your torso.

“Am I-“

“You’re becoming my cock!” She cries in a hushed tone.

“Your…cock?”

“I think it may be a side effect of the potion! Don’t worry, I’ll find a cure, but you’ll have to wait for it to be completely done first!”

Now your torso reshapes, the sides bulging out to create a cylindrical shape, the lighter purple of her shaft creating a border with her sheath as your now limp dick loses all shape, merging with your stomach. You feel momentarily queasy as your organs shift, reshape, and ultimately dissolve. You seem to be getting along just fine without them, though. As you look down to examine the changes, you see your t-shirt fall to the base of your dick body now that your torso is nothing but a large, veiny tube. Suddenly, your neck whips itself up, locking your head in place, looking straight ahead.

You feel a cool breeze on your head and face (or what’s left of it), as the hair falls from your body. Your mouth begins to reshape, turning 90 degrees and flattening, your lips removing all your speech ability. You feel both tubes you used to have replaced with one, which starts to leak a familiar substance. The viscous, salty, but sweet essence powers the rest of your transformation. Your eyes close for the last time as your head flattens out, and your neck puffing out just a bit to match the girth of the rest of the shaft.

You try to speak your last words in a while, but the only thing that comes out is a bubble of pre. Still in her erotic trance, Twilight pumps her shaft with both hands locked, now that it’s grown too big for just one. It’s now reached a length of almost 30 inches long, with a circumference of about half that. The erect equine shaft is even more sensitive, and she feels just about ready to burst. She pulls it up towards her face, and you feel her lips touch what used to be yours. She probes her tongue into her urethra, in a French kiss of sorts. You already feel that she has released, and a rush comes through your body. The salty, yogurt-thick sperm shoots out of your mouth, some of it going in to her own mouth, her mouth in a vacuum seal around the opening. She swallows as much as she can before aiming it back into the toilet, as rope after rope of creamy, gooey cum gushes forth into the bowl. She places one hand on the back wall and aims her now monstrous dick into the toilet. For what feels to be an eternity, but more likely a minute, she came. She had to flush twice during to make sure she wouldn’t spill too much on the floor.

In the afterglow, she yanks your shirt off of you, now musky and slightly damp from being up against her now enormous testicles, and cleans as much spunk as she can off of the head and shaft. You feel the cum get wiped clean, and your body starts to shrink, flopping down. Now flaccid, it still hangs past her knees, a good foot and a half past her skirt hem. You feel yourself slap against her legs as she surveys the situation of both your transformation, and the mess you both made.

“Well, THAT’S going to be hard to explain…” she mutters as the new you-shaft starts to recede back into her sheath. You still can feel a little moisture from the afterglow as you settle into your new temporary residence. She snaps her fingers, and the bulge visible from the outside is no more as it flattens out, and Twilight is just a regular 18 year old purple skinned girl again. “Don’t worry, I’ll see what I can do, but you may have to stay like this for a while. Don’t worry about your homework, I’ll see to that it’s covered.” She gets out of the stall, grabs your clothes and shoes, and shoves them in her backpack, her cum and musk still stinking on your now-soaked t-shirt. She washes her hands, opens the lock, and heads out of the bathroom as the bell rings for 4th period to start. You don’t know just how long you’ll have to wait before you’re human again. But after that experience, you don’t really care right now.
