"So what are you thinking of right now, Jake?" I asked him, watching his hand whacking away at his big dick just like mine was sliding up and down my own similarly large hard-on. "Maybe a girl fingerin' out her pussy and gettin' it all hot and wet, ready for you to eat it...?"
My cousin grinned at me, checking out my chopper getting jerked, as the fattened plum-head of his massive cock swelled more shiny and took on a darker shade of purple. "Sounds pretty good, Shane, but what else you got?"
"Okay... how about some fit dude bendin' over and spreadin' his arse-cheeks open... so you can see his juicy little pucker, lookin' moist and hairy?"
The huge girth of Jake's cock chubbed up still further and became as hard as steel in his frantically pumping hand. The veins webbed across its surface rose upwards in bulbous knots and a sudden gush of precum oozed out from the gaping slit and spread out in an oily sheen across the surface.
"Oh yeah!" he chortled. "That sounds totally fucking hot!"
He flogged himself even faster and I wondered how long he was going to last. His heaving ball-sack strained with the weight of his massive over-filled knackers. I'd always thought that I had a big pair of cods - I used to get embarrassed at school about the way they stood out in two egg-sized mounds on either side of my trouser zipper - but Jake's were a step up even from that!
"I'd kneel down behind him," he grinned, "and shove my face right in there. Have a good lick of his tight little tush!"
"You so wouldn't!" I laughed, surprised how horny I felt to hear him talk like that.
"I fucking would!" he beamed at me, and I knew he really would.
"So let me get this straight," I smirked back. "You'd stick your tongue up some guy's festy brown hole over a girl's hot pussy?"
"Only if I got to fuck him!" he replied, staring at my thick rod as my fist kept slamming up and down it.
"No shit, mate?" I asked. I was getting close myself. "You'd really wanna butt-fuck another dude?"
Jake chortled and nodded but I still couldn't believe it.
"Strewth, like actually do him up his clacker?" I queried, pounding at my dick. "For real, with your dick chockers up his arse?"
"Of course I would," Jake laughed. "I've done it loads of times!"
"What... you mean, with other guys?"
"With guys who are up for it, yeah, why not?! It's just as good as any other sex!"
I couldn't believe what I was hearing - but, God, it was cranking my bone! My cousin rooting other lads' arses while he had a girlfriend he was at it with too!
"And you actually get them to bend over... the two of you goin' at it... one behind the other like a couple of gays?"
Jake laughed again. "There's nothing gay about it! You should try it, Shane! It's the best, man!"
"Better than fuckin' a girl?"
His hand was now pumping his massive prick so fast that the bed was shaking. The headboard right behind where I was squatting was hammering against the wall so loud that his dad in the next room would probably think his son and his nephew were actually doing the thing they were just talking about.
"I dunno about that," he chuckled. "But it's pretty fucking tops!"
"What's so good about it?" I panted, feeling my nuts starting to tingle as the endless thumping of my fist up and down my big shaft right above them made them jiggle about between my legs. "What's so great about shagging another guy's arse?"
"You have no idea 'til you've done it!" Jake gasped. "It's so intense when it's two dudes... the two of you so horny... so sweaty and so up for it... both with rock hard cocks and both desperate to nut off!"
"And you shag them like that? On your bed at uni?"
"Or they shag me!" he grinned. "Or we take it in turns!"
"Fuck!" I called out, my hand a blur on my throbbing bone. The head of it was so bloated and the purple skin was stretched taut and shiny with my goo. "You let other lads stick their woodies up your chuff?"
"I fucking love it!" he beamed at me. "I love having huge knobs splitting my arse in two! Big thick boners with fat bell-ends to really work my boy-cunt and get me gasping!"
He leered at my cock and I knew he was imagining it banging away at his 'boy-cunt' as he'd called it. I cried out, breathless, as my jizz started firing off in long strings from my gaping slit and while I was still cumming, Jake grabbed my left hand and thrust it between his legs, under his giant nuts.
"Feel my arsehole!" he gasped as my sprog kept flinging. "Feel how wide and stretched it is from all the big cocks that have been up it!"
I raised my fingers upwards and groped at how puffy and swollen his huge anal ring felt. It was wet from his sweat and slimy from his bum and the sensation of it, while on one level disgusting, was on another hugely exciting from the knowledge of what had cleaved it open and inflamed its clamped muscle to such an outrageous size.
My cock started spurting with renewed vigour just as Jake's began a much more powerful eruption. I ran my finger around his spasming entrance as he cried out, "Ah yeah! Feel my big fuck-hole!"
Thick ribbons of his cum were spraying from his big pole and he grinned at me, revelling in having me see him enjoy his climax. We both kept wanking frantically, milking our cocks for all they were worth, and as his orgasm subsided I worked the end of my finger up his hot wet hole and grinned into his surprised face when it made him start creaming off more powerfully again.
When our jizz had finally abated and we'd clambered off his bed, we laughed at how covered in spunk we were and how the tip of my finger had a moist brown smear on it.
"All that stuff about bum sex?" I asked him as we cleaned up in his bathroom. "Was it just... you know... wank-off talk?"
"What do you mean?" he asked, wiping his chest off with toilet roll. "Are you asking if I have actually done stuff with other dudes? If we've screwed each other's butts?"
