Pull out your cock

The pressure in your pants is too much. No one can see you from the hall, so you figure it's safe enough. You open your fly and fish out your hard pole. You moan at the release of pressure and immediately begin stroking it.

You study it, wondering if you were bigger than Mark. You'd measured your's at about 9.5", but you were having trouble remembering how big Mark was. You recall it bouncing in front of your face. He had dripped a bit of cum, it must have landed somewhere on your pants. His balls looked smaller than yours, but that might have been because you could see Lukas's huge balls swinging behind Mark's. You knew Lukas's cock was bigger than yours. You got a great view of it when Mark sucked it down right in front of you. It had been amazing that Mark had fit that thing in his mouth, let alone down his throat. And you had definitely seen it slip in. It looked so fucking sexy.

You'll eyes shot open with that thought, but then you feel the cum start to raise in your balls. Thinking about Lukas and Mark have pushed you to the edge of blowing.
