minutes a window opened and a beckoning finger appeared. I left the canteen and followed in his footsteps, entering the uniform store to find a makeshift mattress in the middle of the floor and a stark naked Ciaran. “I don't like to waste time,” he said with a wicked grin. I looked at the windows and he said, “Ah, I don't think we'll have any onlookers today as most of them have already gone home.” As he closed the door I looked at the paint-splattered dust sheet covering the makeshift bed, and it didn't look any too clean, but then neither did Ciaran. "Ah well", I thought, "In for a penny, in for a pound," and started to strip off. By the time I was naked Ciaran had worked himself up to erection and although his cock was now as stiff as a board, there were very few changes in dimensions from when he was soft.

“I may just be able to take that in my arse,” I said, “but my problem is I have a very small mouth, so I'm afraid a blow job's out of the question.” Ciaran laughed and sat on the mattress.

“That's OK,” he said, “With most guys I don't get much more than a hand job.”

As I lay next to him I realised there was going to be no tenderness between us. This was simply going to be sex for sex's sake. There were no tender kisses, no caressing or cuddling, just whip it out, stick it in, and get on with it. I took his cock in my hand and started a slow massage, which elicited a few moans, and I started to speed up a little. “Not too fast,” he said, “I'm halfway there already and I have another two hours before I can clock off.” I laughed and immediately slowed down again.

“Ah,” he said, “that feels grand.” He slipped his huge hand over my cock and rubbed his rough fingers over my exposed glans. I winced at the sensation, but when he apologised I told him that I had quite enjoyed it, even though I was not used to the roughness. He continued to rub for a little longer, then took my whole cock in his hand and started the time honoured, tried and tested pumping movement. I looked down and my cock was totally invisible inside his huge hand, but it felt wonderful.

“Oh my,” he said, “I'm starting to get excited now, could you speed up the action a little more?”

I ignored him and he bucked a couple of times. “Oh Please, please faster, faster”. Again I ignored him. He looked at me like a hurt little boy whose daddy wouldn't play with him.

“This is the speed I'm using and I'm not going to change it for anyone,” I said and continued my gentle pumping. The anticipation of his orgasm was sending him wild and he was like a bucking bronco. When he did eventually reach orgasm he made the loudest noises I have ever heard an ejaculating man make and his love juice shot up in the air and almost reached the fluorescent tubes above our heads. He must have shot almost half a pint of the stuff, and he was still having after-shocks almost a minute later.

“That was amazing,” he said, “I would never have believed that a slow wank
