Jake was still a bit offish with me next morning, giving me a wide berth in the house and keeping conversation to a minimum. After lunch we went to meet a couple of his mates and I thought he might be a dork by dissing me in front of them and taking the piss out of my Ozzy accent, but he wasn't like that at all. If he was still annoyed with me, he didn't show it to his friends and we all had a good time together, first playing 'Grand Theft Auto 5' on one friend's XBox and then out at a skateboard park where Jake could show off his spectacularly awful flips.

As a surfer back in Brissy my sense of balance is pretty sharp and, even though it's been years since I last got on a skateboard, I was back into it pretty quickly and was soon putting the other guys to shame. It was good fun, though - no-one was being particularly competitive - and by the time Jake and I headed back to Uncle Rob's house I felt we were starting to get back to where we had been.

He could just be a sooky git. I'd have to remember that.

While his dad was cooking tea, I went up to his room and he was lying on his bed.

I decided I'd try to raise the subject of sex again as he'd said he was keen to show me stuff and try to bolster my confidence. After my freak-out of two night's earlier, though, he hadn't seemed willing to broach the subject himself.

I sat down on his desk chair and said, "You know that photo your dad snapchatted you of his boner...?"

Jake glared over at me, his eyes hostile again. He snapped, "Let it go, dude. I told you it was an accident. What is it with you getting so hung-up about stuff?"

"I'm not mentioning it 'cause I'm hung-up about it," I calmly replied, determined that this wasn't going to turn into some big spat between us. "I just thought that if you want to send him a reply, we could both photo our two boners and snapchat them back to him..."

His eyes lost some of their belligerence but he still peered at me suspiciously.

"Why would we do that?" he asked.

"Our dicks are pretty similar, we could make him guess which one was which..."

Now he smiled. I knew from a couple of nights earlier that he liked taking sexy pics and movies with his phone.

"But how's my dad supposed to know your boned-up cock from mine? I mean he's seen mine a couple of times, but he's never seen yours..."

"He has," I told him, hoping this would swing things back in my favour. "After you'd gone to bed last night, we jerked off together."

"Really?" he asked, looking half-intrigued, half-incredulous.

"Yeah," I smiled. "I heard him whacking off on his bed when I couldn't sleep, so I went to take a look and he asked me to join him."

"Are you for real?" Jake said. He really was struggling to believe this.

"The really cool thing is," I went on, "he was pushing this cream-coloured rod thing in and out of his butt. He called it anal masturbation and he showed me how he does it."

"Wow!" Jake laughed, finally believing me. "That cream-coloured rod thing is the 'Happy Larry' dildo I bought him for Christmas! It was meant as a joke and I didn't know he was actually using it!"

"Well he sure is," I chuckled back. "He even got on all-fours so I could see it sliding in and out of his arsehole... that's when I pulled my boxers down and started wanking off!"

"Fucking hell!" Jake chortled, jumping up from his bed and coming across to just about hug me. "You really are loosening up, Shane!"

"I'm really trying to, mate! That's why I suggested we snapchat our boners to your dad!"

"Come on, then!" he urged me, grabbing his phone from his desk. "We'll stand against this wall with them poking from our flies."

He scrolled through his photo gallery and found the one of his dad. He passed it to me, grinning eagerly, and I realised I had the old Jake back who I'd had so much fun with the first few days of my stay. I wanted things to stay this way and vowed to keep the mood light and upbeat between us from now on. Flouncing off back to my room wasn't an option if things got too heavy; I'd have to explain my issues to him and hope he'd understand.

I looked at the picture of his dad's big hard-on and marvelled at how incredible it looked, standing thick and veiny and with the huge helmet a deep polished purple. His balls were massive too and hung plump and heavy as though packed full with his spooge.

"Your dad's got such an amazing dick!" I told my cousin.

"Did you wank it off for him?" Jake teased me. "Did you bob your head down to give his helmet a good sucking?"

"Did I fuck!" I chortled. I was loving that we were back having fun as we had been. "But I did grab the end of the dildo thing and push it in and out of his arsehole to make him cum."

"Jesus Christ!" Jake laughed. "I wish you'd told me that this morning!"

"Come on, are we gonna get these photos, then?" I asked, standing up and moving across the wall. "Let's take shots of ourselves like he did - with our jeans pulled down and our bollocks dangling down."

"Well you'll have to pull your boxers right down so they're not in shot - if my dad sees our underwear he'll guess rightaway who they belong to. The number of times he's loaded mine into the washing machine..."

I chuckled at that and pulled my jeans and boxers down. My cock was still mostly floppy but I was aroused enough from our conversation for it to rise upwards from my balls with an outward, drooping curve.

"You're gonna have it get it hard, dude," Jake informed me. "My dad's was rock fucking solid when he photo'd it so we've gotta make ours just as horny to give him a proper reply."

I jerked my foreskin back and forth a bit, trying to coax more life into it, and Jake grinned at me, enjoying watching me wank my big cock off in front of him. I grinned back at him cheekily, pleased that we were being sexy together again.

"I reckon it's gonna need a bit a help, mate," I told him.

"I'll load up the porn drive," he chuckled, heading across to his computer. "You wanna see some rimming stuff... dudes stinkfacing each other?"

"I'd rather do the real thing," I suggested, "if you'd be up for it, Jake."

"You wanna lick my butt again?" he grinned. "D'you think that'll get you hard?"

"It worked pretty well the other night," I laughed. "You have no idea how hard I was in my jeans!"

He laughed back and swung round, pulling his jeans and undies down to show off his bare arse. "Stinkface away, Shaney boy... it's all yours for the taking!"

I smiled and walked over to where he was sticking his butt out. "With your arse, I wouldn't call it stinkfacing, bud. If it was stinky, I wouldn't like it. Your butthole's got a really nice smell... sorta sexy and laddish."

I patted it tenderly, enjoying the twin curves of his two muscular buttocks, before carressing the crease between them and easing them apart by pressing my fingers into his hot, furry valley.

Jake grinned at me before seizing on my admission: "So you now accept laddish stuff can be sexy, then, do you? The other night when I said dude sex could be hot you were all like, 'Ooh, Jake, that's too gay for a pure-bred Ozzy boy like me!'"

I guffawed at his silliness. "I didn't say anything like that! I was just thrown a bit because the guys I know are so into girls... I guess I hadn't realised how much fun it can be for the guys to play around on their own."

"Well now you do know, kneel down and do whatever it takes to get that dick of yours ready for the photo."

"You don't mind if I go a bit further than I did the other night...?"

"Like I said," he chuckled, "just do what it takes..."

I squatted down behind him and pressed my face between his big, supple arse-cheeks. Just like before, his thick, heavy smell lurking among the bristling moistness of his crack made my senses reel from how deliciously sexy it was.

How had I not realised how hot guys' odours could be from all the times in the locker-room I'd felt intrigued by the masculine muskiness of their sweaty bodies and underwear? Why had it never occurred to me all the times I'd been clumsy and awkward with girls that maybe I could feel more open and uninhibited with other dudes like myself?

I pushed my nose into my cousin's tight, pungent arse-crack, snorting deep to get the full impact of its earthy flavours and breathing in through my mouth so I could taste it too. I quickly found his rosebud opening with the tip of my tongue and licked at him hungrily, revelling in his rank rich redolence.

"I'm probably a bit ripe back there," I heard him chuckle down. "All those flips I did on the skateboard got me a bit sticky."

My own cheeks creased into a smile, pushing upwards against the insides of his buttocks. Don't flatter yourself, I thought. The only bits of you that got sticky were your knees and elbows from the all the times you grazed them.

Jake leaned further forwards, grabbing his arse-cheeks with his hands to pull them apart. I pushed my tongue against his pucker, squeezing through it so I could taste the meatier mustiness behind it, and he called out, "Oh yeah! Fuck!" Then he grabbed the back of my head to push my face more firmly between his round, chunky peaches, and I licked at his insides like I was feeding from him, driving my tongue in and out as if I was fucking him with it.

It suddenly occurred to me that soon - perhaps, very soon - I'd really be fucking him like this but not with my tongue: with my actual cock. He'd be bent over in front me, lower than he was now, and I'd be slamming my cock through the wonderful hole I was now feasting on, the two of us gasping and grunting at how incredible it would feel.

I pulled off him and stood up. "Jesus fuckin' Christ, Jake - my boner's ready to bust!"

He laughed like he always did when we were getting sexy - it was a one of many cute habits I came to realise he had - and grabbed his phone from the desk so he could photograph my hard-on.

"You sure like my arse in your face!" he chortled, and I stood up in front of the wall, my big pumped-up cock head pounding and dribbling I was so turned-on from his arse.
