No, you're interrupted.

His tip, about to slide between your open lips. You want to taste him, to have his cum fill your belly. The door knocks.

You look up at Alex, his straining dick needing release. "Quick," he hisses, "under the desk,"

You scoop up your clothes and rush behind the desk, ducking into the tight space. Alex hurriedly sits down, not having had time to pull his pants up, his rock hard tip next to your face. You hear him clattering at his keyboard. "Come in,"

The door opens. You hear a male voice. It sounds like one of Alex's tutorial students. From where you are, you can't hear what they're saying clearly, but it sounds like they're talking about a medieval history assignment.

Alex's dick, rock hard, bobs in front of you with his every movement. It's swollen and red, straining. You see a drop of pre-cum forming. You grin evilly.
