You got busted

"He has been in there for quite some time now." Mark said with a low-voice, so nobody could hear him. He was standing in the hallway of one of the student-dorms and a lot of students passed him.

After he hadn't really seen Alex the whole week, and after he had left so quickly, Mark had decided to follow him. Alex quickly walked over the campus straight to this building, and up to the second floor. Mark nearly had lost sight of his friend as he followed him upstairs, but then spotted him halfway down the hallway waiting before a room. Suddenly the door was opened and Alex entered it.

That was quite some time ago. Alex never came out, nor anybody else. Just what was he doing there? Wasn't that one of the student-dorms? Curious and sick of waiting, Mark slowly went over to the door. He put an ear on the door, perhaps he could hear a thing.

What he heard was quite disturbing. He heard a young woman moan loudly. Was Alex having sex with one of the students?

Slowly Mark opened the door and peeked into the room.

"Ohh, yeah! Alice! You have become good at sucking a cock." Mark heard a woman moan. He recognized her voice, and spotted her across the room. The straight black hair, the long face and the big hoop-earrings clearly belonged to Lexi, one of the students, who he and Alex had encountered two times already, each time ending up in her and himself sucking on Alex' cock.

Before Lexi knelt somebody, but it clearly wasn't Alex. The long, wavy brown hair and the outfit clearly belonged to a schoolgirl, not his friend.

Mark didn't see his friend in the room, so he closed the door. Either he must be at the wrong room, or he had seen wrong and Alex wasn't there.

The door was nearly closed, as Lexi spoke again. "Oh yeah, Alex! You make such a naughty girl! And for a boy you are really good at sucking cocks!"

...

You were surprised by Lexi's words. Did she just call you Alex? She didn't do so since Monday, except during class. Apart from that she either ignored you, or called you Alice, but last only when you were dressed up. But you had no time to think about it. You had to finish her fast, or you would have the nasty taste and smell of her cock in your mouth and nose for longer than necessary. You wrapped your lips stronger around her hard shaft and pressed your tongue stronger against its underside and the tip. Over the last few days you learned that she loved that, especially when you played with her balls at the same time. You felt her cum building up in her cock. So you prepared yourself and moments later she shot her load in your mouth. You tried to swallow her cum as fast as possible, but you had to burp a few times.

"Yeah, that's good, Alex. Now swallow every last drop of my cum."

You didn't understand why she commanded you to do so. The last two days you had swallowed her cum on your own, without her telling you. So she knew that you would do it, or else she would make you do so. You swallowed every drop of it and licked the leftovers of her cock.

At the same time you looked up and saw ... that Lexi wasn't looking at you. She was looking over your head to the other end of the room. And she ginned. What was there? Had somebody come in? Was somebody seeing you blowing her?

You finished cleaning Lexi's dick and regained control. You let go of it and turned around afraid of what you might see. You were shocked as you saw the door being opened and somebody standing in it. But it wasn't just somebody, it was Mark, your best friend. And he had just seen you dressed as a girl and blowing a cock.
