I looked over at Dad's naked body lying next to me in the king size bed, half covered by the sheet and as I ran my eyes over his broad muscular back and what I could see of his firm glutes, I thought how lucky I was.
For the last few weeks, I've been spending weekends with my Dad and we've been satisfying each other's needs in the bedroom, or anywhere else in the house for that matter, as the mood takes us.
It's not really enough though, after spending practically every moment together on holiday, sharing everything, which made it so intimate, it means this weekend thing doesn't really do it for either of us.
We can't seem to get enough of each other, both of us having the same high sex drive, like father like son I suppose, so it was inevitable how things would turn out.
Last night I moved in with him and rented out my flat to a friend. It was Dad's suggestion, which I had no hesitation in agreeing to, so here I was on Saturday morning, waking up with my Dad next to me.
I moved across the bed and snuggled up behind him, my arm across his body and my morning erection against his crack.
He pushed his behind back against me.
"Do you want to fuck me, Ben?"
Did I want to fuck him? Definitely. Although I was happy to have my Dad use my arse as often as he wanted, I did like it the other way round now and again. It was something which he seemed to love now as well, having his boy's cock inside him, filling him with cum.
As he turned onto his front, I got down between his legs and parted his muscled cheeks, exploring with my tongue.
"Nice Ben. Rim your Daddy's hole."
I probed his pucker with my tongue, till he opened up for me and I could get the tip of my tongue in, along with my saliva, licking and stretching him, ready for my cock.
Already dripping with precum, I entered him, till the length of my shaft was buried inside him.
He squeezed my cock with his arse muscles.
"Feels great Ben. Now fuck me."
I thrust against him, my groin hitting his firm glutes as I slammed into him.
Looking at him underneath me, I was always amazed that this strong, masculine man would lie down and let me penetrate his hole and fill him with my seed.
I turned my head towards the mirrored door and watched myself pounding Dad's arse, my cock sliding in and out between his cheeks, pinning him to the bed.
As I rammed him, Dad gave me some encouragement.
"That's it Ben, fuck my hole. Harder, harder. Use me. Give me your cum."
Dad was really getting into it and it turned me on to see how much he was enjoying getting fucked.
There was no way I was going to last much longer, as I felt the sap rising and my balls tighten, letting me know I was going to shoot.
The first wave was so intense that I cried out, as the cum gushed from my cock and filled Dad's hole. Two more spurts followed, then I collapsed on top of him.
"Great fuck as always. I can't believe how much I love you being inside me, Ben."
"Hey, one of my favourite things, Dad."
"And the others are?"
"Mmm, let's see. Your cock in my mouth, mine in yours, the taste of your cum, your big hard cock in my hole, the list goes on."
"Well it's only early morning, so I'm sure a few of those things will happen later."
Showering together to save time, which didn't really work, as there were too many distractions, we had a leisurely breakfast, then drove to the big out of town supermarket.
Halfway down the fruit and veg aisle, my eyes were drawn to the rear view of a stocky, fit man, bending over the butternut squash.
He was wearing a tight grey t-shirt and close fitting dark jeans, that displayed a very well shaped round bottom.
When he stood up, his t-shirt was stretched across a broad chest and you could see the shape of large nipples pushing against the fabric. His head was shaved and although he couldn't be called handsome, he had a friendly open face.
He turned as we passed and Dad broke into a smile.
"Neil, good to see you."
He smiled back and looked from Dad to me.
"Oh, Gary I didn't notice you there and you must be Ben."
We chatted for a few minutes, then moved on.
Dad reminded me that Neil was the new guy at rugby training that he'd told me about. Just divorced in his 40s, he'd come to training for some company and as most of the guys there were about his age and many of them had also got divorced, he fitted in well.
I turned my head back up the aisle and took another look at his arse.
"Seems like a nice guy, Dad."
"He's just a bit quiet so nobody really knows him very well yet."
We got on with the shopping and it wasn't till we were back home having coffee, that I mentioned Neil again.
"So, Neil must be a welcome addition to the team, Dad"
"You think so?"
"Well he's built for a game of rugby isn't he, stocky build, muscles, solid legs and that chunky rear end."
Dad started laughing.
"I wondered when you'd get round to his arse. You think he's hot don't you?"
I had to admit to him that I did. There was just something about his body that I found really sexy and his meaty arse was very tempting.
Dad just shook his head and changed the subject.
In afternoon, I went for a run, although my preference is first thing in the morning. I just wasn't sure how often that would happen, now that I was living with Dad and waking up next to his erect cock every morning.
When I came back, there was no immediate sign of Dad, but I found him lifting kettle bells in the back room, looking so sexy.
All he was wearing was a pair of tiny black shorts that barely contained his package, which was pushing against the fabric as he swung the kettle bells around.
There was a sheen of sweat on his chest as he flexed his muscles.
I walked towards him and licked at the sweat between his pecs, making him shiver.
He carefully lowered the kettle bells and put his hands on my arse, as I covered his mouth with mine and ground my cock against his.
His hands went up inside my shorts to massage my cheeks, kneading and squeezing, making me moan deep down in my throat as a finger probed my hole.
I could feel his erection throbbing against mine and put my hand over it and squeezed lightly.
It was his turn to make guttural noises.
