The steam of the shower washes away the grime from a very exciting day. The Winter Wrap-up was another huge success, as it has been every year since Twilight took over as the manager. You remember how much of a fiasco it used to be, compared to how smoothly it's gone since.

As you finish drying off, you look at yourself in the full-length mirror. Your physique isn't quite as impressive as most earth ponies, though you do have a nice toned look to you. You don't have any facial hair (whenever you try to grow it you just end up with a patchy mess), and your face is a little on the softer side, compared with some of the more rugged stallions in town such as Big Macintosh. Still, Twilight likes it (she calls it bishie) and that's good enough for you.

Fortunately, though, you've got plenty in the lower department. Being an earth pony will do that for you. Twilight herself called them a "fine specimen of male pony genitalia" (of course, on that particular day, you made the mistake of asking what she was comparing it as. You learned quickly not to shoot your mouth off in the bedroom, as it quickly led to boner-killing awkwardness. Of course, it was already starting to get derailed as Twi went into lecture-mode; once she does she loses interest fairly quickly).

You are suddenly startled as the door opens. Twilight walks in, still in her work clothes. Even after her coronation, she still wants to do things the hands-on way. She smiles at you in an almost predatory manner, and one of your hands goes to cover your plothole as you remember the other night in her study. Not that you didn't enjoy it, but it was a bit extreme.

Twilight notices your actions and giggles. "What's wrong, not ready for another round with the Appendages?"

"Yeah, as much fun as that was, I would like to walk and sit down every now and then."

"Well, I think I have another... idea that we could try. But it's a bit different." She keeps staring at your stallionhood.

You look confused. "What, more different than the Appendage in my anus?" She whispers in your ear. "Well, that is different. Umm, it's fully reversible, right?"

She nods empathetically. "Of course it is! I would never do that to you otherwise. I like your current setup too much to risk harming it."

"Oh, yes, the one thing I can count on is your love of my-AAACK!" You recoil as Twilight shoots a magical beam into your junk. The sensation is quite bizarre as your cock and balls are enveloped in an aura of transmutation. As this occurs, Twilight lifts her skirt and takes off her panties. A beam of energy connects your crotch with hers, and an orb of light travels down it. With a flash, you see Twi flush as a full stallionhood appears on her crotch.

You look down to where your own used to be. Both your shaft and balls are gone, and in their place is a pair of smooth lips and a small little nub of flesh.

"Okay, that happened," you mutter. "I have a snatch." You have very mixed feelings about this. On one hand, your marefriend just took your junk. On the other, she did promise to give it back, and your new slit is looking very enticing right now. You notice one of your hands snaking down to it...

"Well, that didn't work quite as well as I'd hoped," Twi says, looking down. "I appear to be... somewhat flaccid." You do notice that she seems to have yet to pop a boner. You think you can fix that.

Leaning back against the bathroom wall, you say, "I think I have a fix for that. I'll give the... Aperture a test drive." You spread your legs a bit, and slide your fingers down between them. With the lightest touch, you trace the outline of your slit, going over first one lip, then the other, and ending with a brush against your clitoris (Because you have a clit now. A part of you's still wierding out about this). That part is quickly silenced as a sigh escapes your lips; the sensations you are experiencing are new and exciting.

Feeling a little bit more adventurous, you reach your other hand down. With one hand, you pinch your clit between your thumb and index finger and begin gently massaging it. This sends shivers up your spine, eliciting a quiet moan. With your other hand, you push a finger in between your lips, and begin gently probing the inside of your pussy. You stroke the inside of the lips, and then move further up into the tunnel, adding a second finger. Your breath shortens and your moans become more frequent, as moisture accumulates on your fingertips.

"Ahem," Twilight clears her throat. You break out of your deep concentration and look her over. Not only are her wings now flaring out in a positively vulgar display, but the Appendage is now popping a major, throbbing boner. "Remind me to give you a show next time. That is, when you've got your proper bits back."

"Take me," you breathe, and spread your legs some more.

Twilight moves up to you, and drapes her arms over your chest and shoulders. "You certainly are taking to this rather well," she whispers, and begins licking your ear. The tip of the Appendage brushes up against your snatch, and you feel light-headed. She moves her lips down your jawline, and french-kisses you for a while. Then she begins to nibble at your throat.

"Oh, Twi, just put it in already..." you moan, feeling exceptionally turned on at this point. Behind you, your tail shakes rapidly in building anticipation.

She looks down, and fumbles with her shaft, trying to line it up. "Come on, how do you work this dang thing?" she mutters, and you giggle. Finally, she lines it up, and slips the tip in. "Ready?" she asks, gently running a hand through your mane. You nod, and she pushes inward, penetrating you. You gasp at the sensation, as the thick, meaty member forces its way through your wet, inviting folds. You can feel the resistance as it stretches and stimulates your new inner passage, and you cannot focus on anything more than the feeling of having it inside you.

Twi begins humping you with a steady rhythm, and you thrust your hips forward in time with her, panting heavily. You run your hands up her back, taking ahold of the corded muscles at the base of her wings where they affix themselves to her spine. Gently, you caress the soft downy feathers, massaging the tender, erogenous flesh and encouraging her to push on harder. Her own breath deepens, and the two of you stare deep into each other's eyes, hers windows of compassion and love.

Her own hands have not been idle. With one hand she moves down the small of your back, down towards your butt. Given recent events, you are starting to seriously give credence to the idea that she only dated you for your ass. Or at least she has a great fondness for it. The other hand moves over your chest, massaging your pectoral muscles and fondling your nipples.

You continue to work her wings with one hand, while the other returns the favor, slipping down the small of her back, running through her tail and then grabbing ahold of her buttcheek. You massage the plump, supple flesh even as she squeezes your own butt, eliciting a moan out of you. Considering, you raise a finger to the hollow just beneath her tail dock, and start massaging there. This provokes an exceptional response from her.

"Keep that, unnfff, up, and I might cum, unff, too soon," she grunts at you.

"Then, nnnggh! finish me! Hump me harder, 'till I can't see straight!" you cry. She envelopes you in a magical aura, and lifts you up. As she pulls out, you notice firsthand just how wet you are.

"I seem to remember how to make you cum," she says, and positions you face down, ass up in front of her. She then grabs you by the flanks and impales your snatch on the Appendage. She begins pumping in and out of you at a rapid pace, and using her magic, pulls your tail to the side. A purple dildo of force appears, and begins lightly probing at your backdoor. She uses her fingers to massage and widen your plothole, until eventually the dildo can slide all the way inside.

Very quickly she establishes a consistent pattern of double-penetration, with one shaft going in at the same time the other shaft pulls out. Your eyes roll back, and your mouth is a sloppy grin with your tongue lolling limply out. You can feel your tender insides forced apart by hard, hot meat and magic with each thrust. It does not take long for you to fly over the edge.

"Oh princess, oh princess ohprincess ohprincessohprincessohprincess...I'm cumming!" You feel a tidal wave of liquid heat flow over and through your body, seeing colors swirl behind your eyes. For a moment, there is nothing more than the blissful state of satisfaction that you baste in.

When you become lucid again, you notice that there is a thick string of semen dripping out of your marehood. "I've been creampied," you say in a somewhat detached voice.

Twilight takes a damp hand towel, and begins to use it to wipe you down. "That was... certainly an experience for me. I trust you felt similarly?"

"Yeah," you say, laying on your back. Your hand gently reaches down to stroke your kitten. "I think I made a new friend..."

Author's Notes:

I think I'll hit one or two other fetishes before I get to the final part of this one. In the meantime, enjoy!
