No, you decide you can control yourself

Looking over at Amber, you see that she's returned to looking down in shame. You're certain that she would do anything you ask of her but you decide you want to try to stick to being the person you in this reality were (or are).

You look over the professor and say, "It's no distraction sir. I'm fine, please continue."

Your cock continues to strain your pants but you focus your eyes entirely on the professor and not the sucking sounds you can now clearly hear. The professor shakes his head and goes on. "Well, you do have quite unusual beliefs. You'd probably enjoy talking about it with Professor King in the philosophy department about them. Anyways, Mr. Johnson, I normally assign seating based on the first class but I'll make an exception this year. Please pick the right row for you next week and that will be your place for the rest of the term. We do not need another incident like today. Are we good?"

You want to lean forward and shake the professor's hand but your cock remains hard. You simply nod and take your hand to move your cock inside your straining pants so you can stand up. The professor shakes his head again but stands up and shakes your hand. You can now visibly see the sucking girl underneath him but you nod towards Amber who jumps up and follows you as you two leave.
