I (19M) was joining my dad on a short vacation at a resort during spring break. My dad had just finished a work trip in the area and so we decided he would extend his time there a few more days and I would join him. My Mom and sister couldn't join us.
As we got undressed for the beach the first day I arrived, I started to see how much more jacked my dad had gotten since I last saw him. He's always been fit as a former college athlete but having both kids out of the house really seemed to have made a big difference. But he has always had good genetics. He's got a full head of hair in his late 40s. Muscle memory is real y'all and his body is looking like those pictures he showed me from his 20s He's still looking a good 5-8 years younger.
My dad remarked on how much more lean and broader I've gotten as well. Credit my coaches for whipping my ass into shape. But we play different sports and even at the same height, where I look lean and athletic, my dad looks strong and powerful. He's looking like those MensHealth models highlighting "Fit at Any Age". If he wasn't my dad I think I'd hate him.
He got lots of compliments those few days from many guests. I can remember a good one - a very sophisticated older woman from Florida said my dad looked like a cross of Gregory Peck and Harrison Ford. She was also a classic film fan I guess. With all these interactions I did notice that this resort had a great mix of guests. Of course being a college aged dude, I noticed lots of the girls with the big tits and ass that this country is known for. The scenery and people watching was top notch.
On the last day of the trip, I got to go scuba diving. That was the day my dad and I went on separate activities as he wanted to go biking.
Scuba diving was an absolute blast for the short while that we were there. Unfortunately about half way through we got a warning about rough waters and so the diving had to be cut short. It was a major bummer and we returned back to the resort early.
Arriving back to the resort I headed for our room to take a shower and figure out what to do for the rest of the day. It would be hours before my dad got back.
But once I arrived close to our room, I could hear noise coming out of it. Music was playing and it sounded like multiple people were in there. I thought it was the cleaners but then I saw a do not disturb hanger on the door.
I had the good sense not to knock in case a potentially dangerous situation was at play. But I knew I could sneak a look through our balcony as there was a large tree directly outside which would camouflage me as I snuck a peek or listen through the window.
Once I quietly got to the window I saw that a lot of the blinds were closed but through some gaps I could now very clearly see what was going on. My dad naked and having sex... with another woman. He's laying back on his bed and this woman with long almost black hair and a really juicy ass is riding him. Eventually she turns around and begins riding him reverse cowboy. Then I can fully see her fully - long black hair, tan/olive skin, big bouncy tits, juicy ass, thin waist and slim everywhere else. She's gotta be in her mid 20s. âĻâĻI can hear their moans even with the music. They're really into each other.
I'm frozen in shock. There are so many conflicted feelings swirling in my head. Including hurt and betrayal but the most prominent one is that i'm so turned on I can't stop watching.
Eventually they decide to switch positions and they make out for a bit. I see my dad's rock hard cock twitching with excitement. She lays on her back on my bed and my dad slides back in and starts pumping in and out of her. I switch to another opening through the windows and curtains for a better view. My dad fucks her hard and deep as she begs for it. She looks so happy to be having sex with my dad. Eventually she moans
"I'm cumming again," In a Spanish accent
And I see her full body orgasm, eyes rolling back, as my dad is deep inside her. I'm rock hard watching.
"Fuck that was the second time...You're so wet" my dad says
"Yes you fuck me so good"
They switch positions again and my dad slides back in and slides into her doggy style. He grabs her hair and continues fucking her deep. I can see his expression through the mirror and he's in heaven. He slaps her ass as he claps his cheeks making them red. I see him wiping a bit of sweat off his face and flexing for him. Growling, animalistic.
