Straight student’s glory hole-3

He let me go and I slipped my glistening, wet cock back through the hole. I squatted down again, ready to reciprocate, keen to give him the same treatment. He stood up. I licked my lips to get them moist and waited to receive his young tool. But he just stood there, his cock hanging semi-lip, a dribble of cum hanging from its head. It was a gorgeous, smooth piece of meat that I had tasted only briefly and now may never taste again. It was too late. He had cum while blowing me. He was showing me the effect my cock had had on him.
I put a finger through, beckoned him closer and, when he did put his flaccid cock up against the hole I just took it in my mouth and held it there for a while. And then I let him go. Heard him do up his combat trousers and leave the cubicle. I dried myself off and did the same.
When I stepped back into the enforced silence of the library I saw him walking away. He stopped at the door, turned around and looked at me. I sat at a table, pretending to glance over a newspaper. After a few seconds he came back and stood in front of me. He lent down.
