Dripping with sweat, I took the lift up to our apartment, dying to get in the shower.
I'd missed my morning run for the last two days and was determined to get out today, so had done the length of the prom four times, on what had turned out to be an exceptionally hot morning, hence me being drenched in sweat.
There was the obvious attraction of sex if I'd stayed in bed, but Dad hadn't tried to stop me, knowing that my running was important to me.
He was up and about when I went in, wearing just his underwear, organising breakfast in the kitchen area.
"Good run?"
"Yep, but far too hot. Just going to hit the shower."
He was busy at the sink, so just raised a hand as I passed, to let me know that he'd heard.
I stripped off, dropping my sweaty clothes on the bathroom floor and stepped under the shower, letting the water run over my head and lathering my chest with shower gel.
I didn't hear him coming, but suddenly his hands on my arse.
"Thought I'd come and help."
He soaped up his hands and began washing my back, his touch giving me a little tingle, like always.
He worked his way down my body, his strong hands rubbing the soapy lather over my skin.
When he reached my behind, he lingered for a long time, massaging my arse cheeks, before inserting a finger into my hole, followed by two more, as he probed and stretched my fuck chute.
I felt his erection brush my thigh and that was what I wanted, his big cock penetrating my hole.
I didn't have to wait long.
A little nudge and then his thick shaft was inside me, filling me completely, as he slid his arms round my body.
Knowing that I was about to be well and truly fucked, I braced myself against the tiles and pushed my bottom out, to let him get further up my back passage.
"Good boy, Ben."
I tightened my arse muscles round his cock.
"Come on Dad, slam that cock into me."
He pulled almost all the way out, then rammed back in to the hilt, shoving me forwards and pumping his hips at speed, giving my hole a good hammering.
I couldn't believe how much I loved having this man's cock inside me.
Although I'm quite adventurous in the bedroom, I don't bottom for every man I'm with, but I would let my Dad have my arse anytime, day or night.
He was really going for it, desperate to come, like always.
"You're going to get my cream any time now."
His low sexy voice in my ear, combined with what he was doing to my arse, made me ejaculate, without even touching my cock and I saw a big gob of semen hit the wall in front of me, slide down the tiles and get lost in the water.
Almost at the same time, Dad groaned loudly as he filled me with his hot cream, just like he'd promised.
Still holding me round the chest, Dad rested his head on my back. We stayed that way for a minute, still joined together, before finishing the shower, that I'd started some time ago.
As we dried each other, Dad kissed me and looked straight into my eyes.
"That's a great way to start the day, Ben."
I had to agree and I'd fitted my run in as well, so it was all good.
We didn't dress, but by the time we'd finished breakfast, we felt hot again. We tried taking our coffee on to the balcony, but the intense heat hit us as soon as we went out.
Now the problem was, what to do with our day. There was no breeze, so the beach would be far too hot and even walking around would be draining.
I remembered a large shopping and leisure centre I'd been in once, further along the coast which was fully air-conditioned. I suggested we go have a look and maybe stay for some lunch.
Dressed in chinos and polo shirts, because it was an upmarket place, we boarded the bus, also air-conditioned, thank goodness, for the half hour ride to the centre.
It was like I remembered, full of designer shops and smart restaurants, but, most important, it was wonderfully cool.
We wandered slowly round, looking in windows, but many of the shops were way out of our price range.
One shop caught Dad's eye. A small menswear place, selling colourful short sleeved shirts and chino shorts.
"How about we buy some smart shorts. They'll be cooler for eating out later."
Inside, two salesmen were standing chatting, but the older of the two immediately came forward.
"Buenos Dias, my name is Eduardo, how can I help."
Eduardo was about 40, carrying a bit of weight, but still handsome in his pink shirt and designer jeans, as he eyed up my Dad.
As soon as we explained what we were after, he whipped out his tape measure to get our size.
He did me in two seconds and called out to the younger guy to bring stock, for me to try on.
Dad seemed to take a lot longer to measure, as he spent ages checking the tape, even crouching down for a closer look, his face about six inches away from the bulge in Dad's chinos.
The younger salesman, helped me choose a couple of pairs to try on, while Eduardo picked some options for Dad.
I chose the second pair that I tried, but came out wearing them for Dad's approval.
"What do you think of these, Gary?"
He made me turn round.
"They look good, Ben. Fit really well across the rear. Don't you think so, guys?"
They both agreed that I looked very smart. Then it was Dad's turn.
He came out wearing a pale blue pair, quite slim cut, that gripped his thighs and accentuated the bulge of his cock, which was looking suspiciously perky.
