Madison and I finally worked our way out of our hotel room. I had gone down on her twice after shaving her pussy almost bald. She put on the tight, white mesh bathing suit I had planted in the room, and was wearing a very thin, very small cotton top and a pair of micro shorts as we left the room and headed down to the beach.
I was wearing a tight pair of Speedo briefs underneath my bathing suit to prevent my bulge from becoming apparent. I had no doubt my dick would be hard all day.
"There's one more thing about wearing that bathing suit Madison," I said.
"No more rules daddy! I'm 18 years old!" she replied. By our banter, you would never be able to tell that we had just had an hour's worth of oral sex.
"If you're going to wear the clothes in that bag, you and I are going to have to be a 'couple' at least for the remainder of the trip. I'm not going to be fighting off a bunch of 18 year old boys," I said sternly.
"Don't worry daddy!" Madison replied. "You are the only man for me this week!"
We made our way down to a busy spot of the beach. Madison very lazily removed her top and bottom. Both men and women stared at her amazing body. I pulled out the sun tan lotion and rubbed it all over her back and ass, as she worked it into her arms and legs.
She began to rub lotion on my back. "Have you been working out?" she asked.
I had in fact been doing so for the last few months. I didn't want to look like a slob for our trip.
"A little," I replied.
We enjoyed the sun and eventually made our way down to rent a couple of jet skis. We were both pretty good on them, having spent almost two weeks at a lake a few years earlier, motoring around on them.
Later that afternoon we decided to go back to the suite to get a late lunch and rest a while before heading out that night.
The bellboy who brought our lunch could not keep his eyes off of Madison. At this point her Greek/Mexican heritage was a huge asset as after only one day in the sun, her skin was already a golden brown. Of course the fact that most of her tits and ass were hanging out was part of the equation too.
We both ate our cheeseburgers and decided to go out on the town that evening. I laid down to watch some TV. Madison put on her headset and dozed off under the air conditioning.
She looked amazing. I studied her body. She was still wearing the white bathing suit, and her breasts were barely covered. I felt my dick getting harder but thought better of jacking off. I wanted to have something left for that evening, even though I wasn't sure if anything else would transpire between us.
At about 5 p.m., I got up and decided to take a shower. The hot water felt good as I washed off the remaining sand, sun screen and salt water off my body. I heard the door open and I saw Madison approach the stand up shower. She was naked.
"Can I join you?" she asked.
"Do you think that I would say no?" I replied.
She laughed and got into the shower. We both showered as if this was all very normal. With the exception of my erection, nothing unusual was going on.
"Wash my hair dad," Madison asked. I got the shampoo and lathered it up for her.
As I rinsed the shampoo from her head, I felt Madison's hand grip my dick. "How big is this dad?" Madison asked.
"Not as big as you might think. I think that maybe you haven't seen too many. It's pretty average," I humbly replied.
Madison began to slowly stroke my dick. My breathing became shallow. I placed my hands over her soapy breasts and played with her nipples, closing my eyes.
"I've seen a few dad," she said, "and this one is the biggest. Well at least it's the fattest. I can barely get my fist around it."
I let her continue to stroke my dick for a few minutes. I finally grabbed her arm and stopped her.
"I don't know what's going on here, and I don't know what's going to happen, but I don't want to blow my wad here in the shower baby," I said.
Madison turned around and seductively kissed my neck and worked her way down to my left nipple. She gently sucked it for a minute and then gently bit it, before working her way back up to my neck.
"You can't be a pussy tease dad," she said. "I want you to fuck me tonight," she whispered in my ear.
With that she finished up her shower and again left me with an amazing hard on in the bathroom. I decided to leave my hard on alone and finished up too.
We both got ready for our second evening on the town. I wore a cabana shirt with silk shorts and sandals. Madison wore a black lace bra with a black lace g-string. She wore the white mesh top and black leather mini skirt with a pair of three-inch high heels. She looked incredible.
We went to a pretty swanky restaurant and each had a shot of very expensive tequila. We then made the rounds at the various clubs in Cancun. All eyes were on Madison everywhere we went. I'm sure people were wondering what this incredible young woman was doing with an old guy like me. If only they knew.
At our last stop of the evening, Madison and I were locked in a very sexy dance. She was grinding her ass into my crotch with no shame. People stared as it became obvious that I was getting hard.
"Let's go back to the room," she said. I made a stop at the little boys' room first. A young man approached me and offered me a variety of drugs.
"I also have Viagra senor," he said. "I saw you dancing. You're going to need it!"
I laughed off the last comment, and decided on buying a couple of joints and also bought a few condoms as well from the bathroom vending machine.
During the cab ride back, Madison could not keep her hands off of me. She was a little drunk.
"Babe, you have to cool down, we don't want this guy to crash into a palm tree because he's too interested in what we're doing," I said.
Madison laughed. "Hey taxi driver, do you speak English?" Madison asked.
"A little," he replied.
"Well this is my stepfather and tonight he is going to fuck me with his big, fat dick," Madison laughed.
The cabdriver laughed either not fully understanding or assuming she was kidding. "I hope he spanks your ass first," he said.
