Background: [The older part of the university grounds were fairly unused. The old toilet block (still cleaned, though) and the old garage sheds were isolated these days. Only used by academic sports-persons on their way to the fields beyond. Things were quiet here, except when someone needed some 'alone' time.
I followed Jill's brother down to the old toilet block that warm afternoon. He didn't notice me, but I saw him alright.
I climbed up just under the old roof. Was easy to get up there and I had an unhindered view of the whole room.
Jill, his sister, wanted to know what he was up to as he wandered about the campus.
That night I called her, and let her in on what I had seen.]
Hey, Jill, today at uni I was peering over the top of the old toilet wall at your brother. Yeah, it was randy Tuesday, you were right!
I'd seen him earlier perving on those Jones sisters. You know them. Alison and Gwenda, putting on their running shorts and playing around.
You know how sexy those bitches can be.
Anyhow, when they moved on he was so stiff he could hardly walk, so he went into the toilets and up to the wash basin, dropped his pants, grabbed his naked cock and began to jerk.
Guess who came in while he was stroking his cock?
It was David, that skinny boy from Anita's geology lecture class.
Never took much notice of him, till now.
Well, that David kid got in a position where he could see your brother pumping his cock. He let his pants fall down as he looked on and pulled his shirt up under his armpits.
I watched as his cock grew. It started sticking straight out, was firm yet filling with fluid. The cock-head emerged from its foreskin as the shaft became more rigid. Gradually it stood erect and bumped on his flat tummy. I could sense it throbbing.
It looked like it enjoyed being out of his pants.
His balls were pulling up and tightening with excitement and lust.
(Fuck Jill, we gotta call a party with this guy.)
Your brother took no notice and started to pump his cock steadily, fondling his balls until the shaft became hard and rigid.
He got it erect and really stiff.
Then David started to pump too.
He steadied himself by grabbing his bum cheek.
He was watching your brother, who threw back his shirt so you could see his naked body from his knees up to his neck.
Neither of them wanted clothes to get in the way. They needed unrestricted access to pump their swollen cocks.
They both thrust their hips slightly forward so their hands could stroke the whole of the shaft.
Your brother noticed this other massive cock being stroked so he turned slightly to give the kid a better view of his own shaft pumping.
