	I was just sitting in my room, just after the dinner; with nothing special on my mind.  I know I would come up with something to spend the time on, but that is not quite yet.

As I sit in my chair, turning my back towards the wooden desk; I hear the sound of knocking on my door.  Of course, it is my sister who wanted to ask me something; she is the only one knocking on my door at this time of the day.

I had been looking at the simple green wallpaper, behind my bed as she was knocking.  There is a double window I could open outwards opposing the door.  Of course; I have a door to my wardrobe between the desk, and the wall.  Her room is basically mirroring mine.



I opened the door; only to see that it truly was the sister, I had expected it to be.  Having nothing better to do, I bid her to enter, and listened to what she had to say.

In the end; I had agreed to follow her into her room, and explore the possibility she was offering me. I had found it sounding exciting enough, for one.

Naturally; I had closed her door after myself as I entered the room, after her.  What she had asked of me was clearly requiring it; and I had no interest in being distracted, or interrupted by anything from outside the room now.



Once alone with her on her room, it is no longer possible to ignore to pick up on the details.  She is clearly wearing the tube she had mentioned before, and it is responsible for her excitement; I assume it is a positive reaction.

Then I had found myself increasingly excited myself, even when it is my very own sister that is the object of the excitement.  I don’t want to ignore it, and I found no reason to resist what I feel; not even when I still did know that it is my sister.



The excitement had started to creep onto her voice, in the form of giggles.  It may be just a slight hint; but I could clearly feel the hints growing stronger, and stronger; guessing that it is the tube, and my close proximity behind it.

As she mentioned how exciting it had been to her, to wear the tube; I had to agree with her on that point.  I could both see and feel the effects it was already having upon her.  Maybe I should agree on trying one of these tubes out for myself; I couldn’t see any harm in it, and she did not give any reason to expect that any such reasons could have been hidden from me right now.

I had applied a slight hint of gel to the inside of the tube, before I pushed the head of my penis into it.  Only then I started to feel the first effect of wearing the tube as I was rapidly growing stiff and firm as I slipped into the tube.  From what I can see, it is merely made out of clear rubber.  It was looking almost as if it had been a condom, and nothing more.

If it is my excitement that keeps me filling it out, and standing firm; or if there is something in the gel or the tube itself, responsible for the effect is well beyond me; I have no experience of these things.  Maybe this is the way it should be, after all.



To my surprise, I could feel the hint of a chuckle on my voice; right after I had slipped the tube on, with the gel to lubricate it, just to make sure it wouldn’t rip.  Enjoyable, or not; I did not like the idea of ruining the item, just out of carelessness.

Then I touched myself, stroking the head in order to explore how it would feel.  Of course it felt good, and almost as if it had been my very own bare flesh.  The tube wouldn’t just come off, but this wasn’t bothering me, right now.  I enjoyed how it felt and wanted to see more of where this was going.

Casually, I picked up what was passing for a rear tube; lubricating it with the same gel as I had applied to the other tube and inserted it with unexpected ease.  Of course, the tube did not slip out as I pulled back my hoof; but what had I been expecting, what fun would it have been if it would slip right out again.



I could feel her pushing me up against the wall in a playful move; which I couldn’t help, but finding exciting in my current state.

While in a bipedal stanch, she spread my legs open; only to find my knees all the way up against the wall before she had actually realized how easy it had been, and that I made no resistance or protest; towards what she was doing.  Maybe I should have protested; if I had had the time to realize it and reflect on what she was doing, but since I never felt any actual discomfort in the imposed pose as such; I never felt the need to protest.  The entire situation merely excited me even further.



She picked up a third tube, clearly intended for my muzzle, which should be making it slip into my mouth, and possibly down my throat.  She picked up the same gel I had used, and lubricated it; before she slipped the tube into my mouth.  I could feel the slippery rubber slide in between my lips, into my mouth and an inch down my throat, before I had really realized what she had been doing.  Now I feel how the tube is covering my entire muzzle, the inside of my mouth and an inch down my throat.

The tube had made my lips contract instinctively and took away my control on the instant of contact.  The effect of contraction flowed down as it slipped into my mouth as well.  Now I feel the rubber pressing outwards on my lips, my mouth and down the throat, just as it is pressing in on my tongue, while I contract firmly and unconditionally around it.

Despite myself, I find it exciting; like nothing before it.  To have the undivided attention of a filly my own age is good, and now it is one I find quite exciting, so I can’t complain here.  Not even if there is a chance that the tube is affecting me to react the way I do.

The next moment; I could feel her carrying me to her bed, where she carefully placed me quietly.  She was intent, not to let on that she isn’t alone in her room; as much as the intent she had on her mind right now.

By the time she had placed me on the bed; I had felt the effect of the rubber spreading out over my entire body, thus holding me firmly in its grip.  She had apparently turned me into a toy for her to play with; the effects had been increasing with the time I had been exposed to the tubes, but even more to the number of tubes I had been exposed to.  The first only made me excited, and directed my excitement towards my sister; who just happened to be the nearest object of my excitement.  The second tube left me fully poseable, as if I had been a doll for her to play with.  Naturally, it is the third and final tube that made the actual effect.  I fear it is part of what it had been for in the first place, yet I can’t make myself regretting my situation.



I see the excitement in her eyes as she bend down over me, cupping her hooves; before she tease me by stroking the head of my penis.

After a moment, she let go of me; before she placed her muzzle on the tip of the head and licked it for a moment.  Only to slip her lips down over me.  Had I not been wearing the muzzle tube, I know I would have moaned; and thus alerted our parents as to what we were doing.



She had made it certain; I knew exactly where the rim of each and every one of the tubes I had inserted into myself, as well as the one I had inserted my now fully erect penis into.
