Still half asleep, I heard Dad's voice in my ear.
"Turn over, Ben."
I obediently flipped on to my stomach, opening my legs for Dad to do whatever he wanted with me.
He knelt between my legs and parted my cheeks, flicking his tongue over my hole. I could feel his morning stubble scratching my skin, as he pushed his way in, using his mouth and tongue to loosen me up.
First one finger, then two more entered me and I felt his saliva drop onto my crack, as he explored my arse hole, stretching me open ready for his cock.
With his first thrust, the entire length of his thick shaft slid easily inside me, filling my back passage with it's girth.
This was the way to waken up in the morning, a fuck from my Dad to start the day.
Unusually for him, he was taking it really slow, but every thrust was going deep up my insides and I almost cried out with the joy of it, having this huge cock penetrate me, especially as it belonged to my Dad.
But he couldn't last forever, much as I wanted it to and five minutes later, his thrusting became frantic, as he rammed into me at speed and with a loud roar, sent his seed shooting up my back passage, the hot liquid flooding my insides and making me so happy.
He lay down and I loved feeling the weight of his body on top of me, his cock still hard, embedded in my wet hole.
We stayed that way for a minute, then I turned my head round for a kiss and found him looking at me intently.
He leaned forward to give me a long slow kiss, cupping the back of my head in his hand.
"Last day today, Ben. What do you want to do?"
"Well we've just ticked one thing off my list. Great fuck, Dad."
He grinned at me.
"Thanks. Let's hit the shower and enjoy our last day."
Showering took some time as usual, but eventually we made it on to the balcony for breakfast, then organised ourselves for a day on the beach.
The gay end of the town beach was a bit tame after the nude beach yesterday, but it was great just me and Dad together. Although I loved the view of his naked cock, he was just as sexy in his tiny white trunks, lying there with an almost obscene bulge showing for all to see.
As the heat increased, we spent a fair bit of time in the sea to stay cool. Dad was particularly affectionate today, hugging me from behind in the water, kissing my neck, with his cock nudging into my crack.
We were waist deep in the water, when he suddenly pulled down my trunks at the back and shoved his erection between my cheeks.
I had a quick look around, but nobody was close enough to see what we were doing, so I pushed back and his cock entered me. That took Dad by surprise.
"You're a bad boy, Ben."
I had to laugh.
"Look who's talking, you started it."
We didn't fuck, just lounged around in the water with Dad holding me and nobody realising that I had his hot rod up my arse.
As we came closer to the beach, Dad took his cock out of my hole and tidied up my trunks.
We walked hand in hand back to our towels, both of us still hard and getting quite a few looks from the other men.
