What Difference Does It Make?

Now I withdrew my finger and, as Michael opened his legs as far as he could, pushed my face right into his arse cleft. My tongue found his hole and slid in easily.

He grunted something like, "Oh fuck! Yeah!" and I tongued his rectum as deeply as I could manage. His arse tasted strong and rough, but I found that my cock was almost bursting from my trousers at the pleasure I was getting from being so intimate with him.

I'd never even done this to his sister!

I pulled away from him and, both of us gasping, said to his disappointed face, "I need to fuck you."

His eyes widened with surprise.

He muttered, "Yeah... yeah..."

I grabbed my wallet from my trousers and pulled out a condom. I unzipped my fly, disentangled my throbbing cock from my briefs with some difficulty, and then rolled the condom quickly down its length.

I said, "On your back. Legs up."

He moved to lie along the length of the mattress, his head on the pillow, but I stopped him. "Not like that. Your arse on the edge of the mattress, so I can fuck you from here."

He struggled to get into the right position and chuckled, "You've done this before..."

"Yeah. Your sister's pretty good at it..."

He got into position, holding his legs up near his shoulders and opening his arse as wide as it would go. I could tell from the size of his dilated hole that this would not be the first time he'd ever been fucked.

He'd clearly been having a little fun in Sheffield.

He said, "Will it work? I mean, my arse is a bit different to... er... what Kaz has got..."

I liked the way he couldn't bring himself to give a name to his sister's genitals. Even though he had quite easily brought himself to seduce her boyfriend.

I smiled. "Like you said, Michael. The fun will be in the finding out..."

With that I plunged my cock into him. My saliva had lubricated him nicely and I slid in quite effortlessly.

He gasped, "That feels so good."

I threw him a smirk. "That's what she always says..."

He smiled back.

I grabbed his legs and held them as I began fucking him gently. He groaned in appreciation.

His hand went to his cock and he began masturbating himself to the same rhythm as I was fucking him. His large balls bobbed around like a pair of ripened apples on a tree.

We were soon both panting and sweating.

I briefly paused once to pull my balls out from my fly. "They're trapped in the zip... they might not as big as yours, mate, but it's still painful..."

Now they hung over the front of my trousers, slapping against Michael's buttocks as I fucked his arse.

I must have fucked him for about five minutes before he came. I think he'd have lasted longer - I was deliberately controlling my rhythm whenever he looked like he was close - but for the fact that I started teasing his nipples between my finger and thumb.

He shot what seemed like a gallon of semen. Big balls produce big loads, apparently.

I quickly finished myself off inside his arse and then, with the condom pulled off, over his crotch, and added my own drizzle to the puddle on his stomach.

Almost as soon as he'd climaxed, I heard his mum shouting up the stairs, "Are you alright, Sebastian?"

I called back, trying to keep my voice steady despite being so out of breath. "Yeah... I've just sorted him out... I'll be down in a sec..."

She called up, "Do you need a bucket for him?"

I looked down at the pool of cum on his stomach and Michael smiled up at me.

"Er... no... I don't think so..."

She called up, "Okay. Well hurry down... I've got some of Katherine's baby pictures to show you..."

Michael grinned. "Ooh lovely..."

Before I left the room to return to them, Michael said, "We'll do this again, yeah?"

I nodded. "Yeah. If you like."

"Yeah."

And then, as I was closing the door, "I bet I can suck your cock better than Kaz can..."

I smiled and whispered back into the room, "Well there's only one way to find out..."

He chuckled and I closed the door.

The rest of my visit was difficult: I found myself performing a kind of balancing act between Kaz and Michael while trying not to arouse any suspicion.

I wasn't sure which of them I preferred.

Kaz was great fun to be with, she understood me well and I'd grown to love her enormously in just the three or four months we'd be seeing each other.

But Michael... well, Michael could fuck like a rabbit and suck cock like a pro. And there's a lot to be said for that too.

I met him on and off throughout the time I dated Kaz. Once we went on a camping holiday - Kaz and I, with Michael and a mate - and I found, again, that Michael and I were getting together every opportunity we had.

The more I got to know about Kaz's body, the more questions it posed about Michael's and, whenever the two of us guys met up, I just had to have them answered.

I'd say something like, "She's really moody at different times of the month. I know you don't get a period, but do you get like that?"

And he'd think about it and reply, "Well maybe it's because she's got big ovaries or something. They're producing more hormones, maybe. I mean, I've got big balls so it'd stand to reason that she'd have big ovaries..."

And I'd nod. "Yeah. I guess..."

It became a developing fascination of mine to find out how some of Kaz's sexual preferences and foibles would be expressed in a male. Most of what Kaz enjoyed having done to her vagina, Michael found very gratifying when applied to his arse. Apart from that, his erogenous areas seemed to match hers and his preferred positions were clearly the male equivalents of hers.

One of the things that saddened me most about the break up of my relationship with Kaz was that I never got to see Michael again. I guess he took her side in the argument we had; he's her brother so you can't really blame him, can you?

I find myself wishing sometimes that my wife Melissa had a brother.

It would be interesting to get to know him.
