Ha! It finally happened this afternoon!
I'm working from home today and was on my laptop in the living-room "working" (watching some pretty good old perve/twink porn) with my cock in my hand when he barges through the front door (which leads straight in to the living-room.
He'd written his shifts wrong on the callendar (I had thought I had the flat to myself) and so... basically caught me wanking off to hardcore gay porn.
He said he'd "leave me to it" and went in to his room, pretty minimal reaction (he's seen it before anyway)... then 20/25 minutes later he comes out, sits down (the porn is off at this stage and I'm kinda embarassed) and he says "i used to be in to that sort of stuff"... and explained that he used to like watching older guys with younger guys on the internet
Turns out that, whilst never having any man-on-man experience (other than our wank-sessions) himself, he used to watch it a lot online and get really turned on
So I pulled up the site I'd been looking at and we both start fiddling with ourselves...
Which leads to fiddling with each other...
Which leads to sucking each other...
Which lead to me fucking his brains out...
...and pissing all over him in the shower!
For about 3 hours we were RAMPANT - it was fucking awesome!
He's gone out for drinks with some of his mates now (I've got work to catch up on) but my God it was amazing
I want more!
We'll have to see what happens
