Rise and Shine

You awaken early the next morning eager to begin your first day of lessons at Hogwarts. Today is Muggle Monday, so you slip into some Muggle clothes, a pair of jeans, a faded Led Zeppelin t-shirt and a brown leather jacket. As you're lacing up your shoes you take a look around your dormitory in the fresh light of the morning sun, and notice something you didn't spot last night; a dark box on the wall, about the size of a phone booth, you have no idea what it could be. You finish tying your shoes just as the side of the cubicle swings open, and Justin emerges, looking slightly dishevelled. He spots you looking.
"Oh, hey, John. Good morning." He says cheerily.
"Morning. What's that?" You reply.
"Oh, this is the greatest feature of the Hufflepuff dormitories, and the reason you're lucky to be in Hufflepuff. Check it out." Justin said, cryptically, opening the door to the booth. It looks like an ordinary, windowless box, you don't see anything special about it.
"I don't get it, is it special in some way?" You ask.
"You might say that, for one, this whole booth is soundproof, which is good considering what goes on in here. You see that hole there, on the far wall, that's a magic gloryhole. You stick your dick in there, it appears somewhere else, and you'll almost always get a nice blowjob." Justin explains.
"Wait....what?" You exclaim. "A magic gloryhole? How does that even work? Is that what you were doing in here? Gross."
"Oh, it's not that bad. Everyone casts Scourgify when they're done, that's Rule #1. Otherwise, if it's open it's free, if the door is closed, it's occupied. Oh and the door locks automatically when it closes, so nobody will barge in on you. Why don't you try it out?"
"What? Now?"
"Why not? If you've got the morning wood, might as well use it for something." Justin says, matter-of-factly.
"Hang on a minute, before I use it, I have a few questions. Do you know how it works? Is it Vanishing my penis?" You ask.
"No, that would be dangerous, as far as I understand, it's more like your dick exists in two super-states at once, but you can feel what's happening to both of them." Justin explained.
"Okay, so you said this gloryhole appears somewhere else. Where does it appear?" You ask.
"Doesn't that kind of defeat the purpose of a gloryhole? Doesn't the thrill come from the fact that you don't know who's on the other side?" He pauses and looks at you, then continues. "Fine. We've managed to pin down a few locations. We know it goes to every girls' dormitory here in Hogwarts, as well as most of the girls' bathrooms. We suspect it sometimes also goes to the staff room. It also goes to several locations outside the school, we've identified the women's bathroom in The Three Broomsticks, the changing-rooms at the Holyhead Harpies Quidditch stadium and another location we're pretty sure is somewhere in the Ministry of Magic."
"That's a lot of places." You reply.
"Sure is." Justin says. "Go on, give it a try. I'll leave you to it."

You hesitantly shut the door to the cubicle and slowly drop your trousers. You've woken up with morning wood, so you're already erect.
"Here goes nothing." You mutter to yourself, and stick your erect dick through the glory hole. It feels warm, as if it's been immersed in warm gel or something. After about five seconds, you feel a tongue start teasing the tip of your penis. Your eyes roll back in your head as the tongue makes its way slowly along the length of your shaft. Whoever is responsible for this blowjob has a tongue-stud, and it feels heavenly on your dick. Whoever it is knows exactly what they're doing as they slowly increase the speed and begin to take your whole dick into their mouth. By this point you are moaning audibly, and glad for the soundproofing. You can feel yourself about to go off and you try to hang on, but to no avail. As your dick disappears once again into the eager mouth, you cum explosively.
What a way to start the morning. You think, as you cast the cleaning charm and put your pants back on.

You emerge from the cubicle feeling great, and slightly glassy-eyed as you can't quite believe what just happened. You head down to breakfast in the Great Hall with Ernie and another Hufflepuff boy who introduces himself as Zecharias Smith.
"But feel free to call me Zeke, everyone does." He says. You follow him into the Great Hall and sit down between Ernie and Zeke to a delicious breakfast. A great way to start your first day at Hogwarts.
